Levofloxacin bioequivalence

Chirality provided by biomolecules Asymmetric photoreactions induced by nucleosides and DNA have been reported for the photoisomerization of Z-cyclooctene [2]. It was proven that the supramolecular complex formed in the ground state between DNA and Z-cyclooctene is an important factor to achieve high enantiomeric excess. Albumins are also biomolecules of interest because of their ability to bind substrates in their hydrophobic pockets. The differences between the binding affinities of R ; - and S ; - ketoprofen KP ; and binaphthols to bovine serum albumin BSA ; have been exploited to achieve the photoresolution of racemic mixtures [3]. Very low photoenrichment has been observed with KP, while efficient photoresolution of binaphthols has been performed. More recently, supramolecular photochirogenesis using BSA and the prochiral 2-anthracenecarboxylate as substrate has been reported [4]. It has been shown that irradiation in the presence of the protein inverts the regioselectivity of the photocyclodimers formation and gives good enantiomeric excess. Asymmetric photosensitization of biomolecules Asymmetric photosensitization of biomolecules can help to improve the benefit-to-risk ratio of drugs. Nowadays, an increasing trend consists in introducing the enantiomerically pure form of drugs to minimize the toxic effect mediated by the less active enantiomer. Among the adverse effects, drug photosensitivity is described with increasing frequence. So, a possible stereoselective photoprocess during biomolecule sensitization would inform about the most photoactive stereoisomer, providing additional data to consider in the switching toward pure enantiomeric drugs. In this aim, models mimicking interactions between photoactive drugs, namely, nonsteroidal antiinflammatory drugs NSAIDs ; , and biomolecules have been synthesized. The ability of KP to realize lipid peroxidation has been modelized by a bichromophoric compound, including a KP unit and a derivative of cyclohexadiene in the role of the fatty acid [5]. Stereoselective intramolecular hydrogen abstraction by the benzophenone part of KP has been observed, the S, R ; -enantiomer being more efficient than the S, S ; . Another interesting example consists in the reproduction of the drug-protein preassociation by the bichromophores tiaprofenic acid-tryptophan and suprofen-tryptophan [6]. These two antiinflammatory agents are regioisomers as they contain the same benzoylthiophene moiety substituted either at the thiophene part or at the benzoyl part. The intramolecular electron transfer was shown to occur regioselectively as well as stereoselectively. Similar results have been obtained with tiaprofenic acid-tyrosine and suprofen-tyrosine bichromophores [7]. OBJECTIVES The objectives of this work were to look for a possible differentiation in the photosensitization of biomolecules by chiral drugs. Until now, investigation of stereoselective photoprocess has never been carried out in the case of whole biomolecules. The fluoroquinolones, such as ofloxacin the racemic mixture ; and its commercially available S ; -stereoisomer known as levofloxacin ; , are antibiotic drugs effective against a broad spectrum of bacteria. They have been reported for their ability to induce phototoxicity, photoallergy, and photocarcinogenicity [8]. Mechanistic DNA photosensitization by racemic ofloxacin has been described to proceed mainly via a type II singlet oxygen ; mechanism. Studies of isolated and cellular DNA showed a mixed type I type II mechanism as alkali-labile sites, 8-oxo-7, 8-dihydro-2'-deoxyguanosine 8-oxodGuo ; , and oxidized pyrimidines have been revealed [9]. The second drug is the NSAID carprofen CP ; . NSAIDs are largely used in the treatment of pain. One of their adverse effects is their potential to induce gastrointestinal disorders. Nevertheless, their ability to produce skin photosensitivity should not be neglected, as severe cases of phototoxicity and.

Table 1: Probable Reasons for Continuing High Mortality in Neonatal Sepsis5 Poor Host Defences in the Newborn. Our inability to diagnose sepsis early. Imprecise understanding of pathophysiology of sepsis. Hence poorly directed therapy. Total reliance on killing the pathogens with inadequate attention to correcting the consequences of the inflammatory process. Newborn babies have fragile skin which is broken frequently by care givers offering pathogens a route of entry into the body. Added to this, newborn babies in particular the preterm have reduced phagocytic, chemotactic and opsonic activity thus reducing their capacity to engulf and destroy the pathogens. Newborn babies also lack the ability to initiate the alternate complement pathway or mount a good antibody response due to lack or reduced levels of antibodies IgG ; which are transmitted through the placenta from around 30 week of gestation Table 1 ; . Host defence deficiencies have already been discussed most elegantly in an earlier issue of this journal12 and will not be further discussed. Nevertheless to make evidence-based recommendations for acute management of sepsis in the newborn, it is important to appreciate the cascade the process ; of sepsis and the immunological imbalance this process creates. Further, genetic make up has a major influence on our ability to deal with infection. This issue will not be addressed except to make the point that it is not the pathogenic organism that is responsible for the outcome, but it is how we respond to the pathogenic organism that is responsible for the outcome good or bad.
B. Johnson, S. Bouchillon, T. Stevens, J. Johnson, D. Hoban, M. Dowzicky Schaumburg, Collegeville, US ; Background: Tigecycline TIG ; , a member of a new class of antimicrobials glycylcyclines ; , has been shown to have potent broad spectrum activity against most commonly encountered species responsible for hospital acquired infections. Crossresistance to several classes of antimicrobials is often seen in nosocomial pathogens. The T.E.S.T. program determined the in vitro activity of tigecycline against strains of Enterobacteriaceae cross-resistant to two or more drug classes that included the following antimicrobials: amoxicillin-clavulanic acid AC ; , piperacillin-tazobactam PT ; , levofloxacin LV ; , ceftriaxone CX ; , cefepime CP ; , ampicillin AMP ; , amikacin AK ; , minocycline MN ; , ceftazidime CZ ; and imipenem IMP ; . The isolates were collected from 77 investigational sties in the United States during 20042006. Methods: A total of 5760 clinical isolates were identified to the species level at each site and confirmed by the central laboratory. Minimum Inhibitory Concentrations MICs ; were determined by the local laboratory using broth microdilution panels. Antimicrobial resistance was interpreted according to CLSI breakpoints with TIG's FDA approved susceptible and resistant breakpoints defined as 2 mcg ml and 8 mcg ml, respectively. Results: 392 5760 Enterobacteriaceae were multi-resistant to two or more drug classes. Of these resistant strains, 4.3% were resistant to TIG MIC 8 ; compared to AMP 99%, AC 54%, CZ 37%, LV 72%, MN 44%, CX 23%, PT 23%, CP 13%, IMP 4.8% and AK 0.3%. the 2, 239 Enterobacter spp. and S. marcescens collected, 106 presented resistance against CX and CZ but susceptible to CP suggestive of AmpC phenotype. 85 106 80% ; of these isolates demonstrated MICs 2 mcg ml against TIG. TIG showed excellent inhibitory activity against members of Enterobacteriaceae that were resistant to AK n 630 ; , and IMP n 59 ; inhibiting 100%, 90.8%, 93.2% of isolates, respectively, at 2 mcg ml. Conclusion: The presented data suggest that TIG is little affected by cross-resistance mechanisms present in these selected strains of Enterobacteriaceae. TIG may be an effective therapeutic option against Enterobacteriaceae regardless of the resistance patterns to commonly used antimicrobial agents.

It was the result of Sir David's international standing and personal relationships with the UK's Royal Colleges that from 1985, the MRCP UK ; examination began to be held entirely in Hong Kong. This was a milestone in the development of medicine in the territory, which set the direction for postgraduate education and training up to the present time. Another of his great perhaps the most enduring achievements was his chairmanship of a working group, which led in 1986 ; to the formation of the Hong Kong College of Physicians. With Sir David as Founding President, the HKCP has been instrumental in ensuring the continued development of medical training and practice to the highest international standards. A sibling organization, The Hong Kong Academy of Medicine, was inaugurated by statutory ordinance 1993, once again with Sir David as Founding President and lexapro.

Answer: A Explanation: Communication error is the most common type of error in the outpatient setting. It is then followed by discontinuity of care, and then by abnormal lab result follow up. The next four errors, although not as common, are well suited to the EMR as heralding alerts. These include missing values and poor charting, prescribing errors of dosage choice, allergy or interaction, clinical mistakes of knowledge or skills, which would include improper diagnosis, and the ubiquitous "other". "Other" is actually quite high. This would include lost charts, improper filing, and violation of confidentiality to name a few. At 8%, or 8 out of 100 charts, applying to the typical daily practice seeing 100 patients a day, this category "other" is actually a very high and unacceptable number. The EMR will assist in reducing this number. Source: Hans C. Hansen, MD 31.

Gonorrhea bacterium under a microscope. This works better for men than for women. Gonorrhea could be treated and health care providers usually prescribe a single dose of antibiotics. The most common antibiotics used to treat gonorrhea include: Cefixime, ceftriaxone, ciprofloxacin, ofloxacin, and levofloxacin. Pregnant women, or people younger than 18 years old should not take ciprofloxacin or ofloxacin, but health care providers will provide the safest and best antibiotic for each individual patient. If left untreated, gonorrhea could cause complications, such as pelvic inflammatory disease and infertility. In untreated infections the bacterium could spread into the reproductive tract and very rarely can spread into the blood stream and infect the joints, heart valves, or the brain. Inflammation of the joints could occur when spread through the blood stream into the joints, which is very serious. When gonorrhea is left untreated in men it can cause epididymitis, which is a painful condition of the testicles that can lead to infertility, and it also affects the prostate gland and causes scarring in the urinary canal. The most common complication from gonorrhea left untreated is pelvic inflammatory disease PID ; , which is a serious infection of the female reproductive tract. PID causes scar tissue to form on the fallopian tubes and if the tubes are even partially scarred, the fertilized egg may not be able to pass to the uterus. When this does happen the embryo may implant in the tube causing a tubal or ectopic pregnancy, which may result in a miscarriage and could cause death of the mother.

Vaccines: Demand for vaccines used in animal health applications will see the fastest growth, increasing 4.9 percent per year to $780 million in 2006. Continuing advances in biotechnology e.g., transgenic expression of viral antigens ; , which greatly enhance the quality, effectiveness and range of available veterinary vaccines, will drive growth. New product introductions such as feline AIDS vaccines and West Nile virus vaccines will contribute positively to product demand in the next decade. Other Animal Health Chemicals: Demand for these products will increase 3.5 percent per year through 2006 to $2.6 billion. The diagnostic chemicals sub-segment will see the strongest growth through 2006, benefitting from advances in biotechnology, increasing availability of pet insurance and an aging pet population, among other factors. Therapeutic antibiotics will see the slowest growth as their use in food animals will continue to be called into question due to concerns over increased antimicrobial resistance in humans and nabumetone. 11 22 2005 TOS 1 Proc Cd J0289 J0290 J0295 J0300 J0330 J0340 J0350 J1270 J0286 J2310 J2210 J2240 J2250 J2260 J2270 J2271 J2275 J2353 J2300 J2175 J2320 J2321 J2322 J2324 J2330 J2350 J1890 J2280 J1980 J1250 J1930 J1931 J1940 J1950 J1955 J1956 J2185 J1970 J2180 J1990 J2000 J2001 J2010 J2020 J2060 J2150 J2354 J1960 J2680 Description INJECTION, AMPHOTERICIN B LIPOSO INJECTION, AMPICILLIN, UP TO 500 INJECTION, AMPICILLIN SODIUM SUL INJECTION, AMOBARBITAL, UP TO 12 INJECTION, SUCCINYLCHOLINE CHLOR INJECTION, NANDROLONE PHENPROPIO INJECTION, ANISTREPLASE, PER 30 INJECTION, DOXERCALCIFEROL, 1 MC INJECTION, AMPHOTERICIN B, ANY L INJECTION, NALOXONE HCL, PER 1 M INJECTION, METHYLERGONOVINE MALE INJECTION, METOCURINE IODIDE, UP INJECTION, MIDAZOLAM HCL, PER 1 INJECTION, MILRINONE LACTATE, 5 INJECTION, MORPHINE SULFATE, UP INJECTION, MORPHINE SULFATE, 100 INJECTION, MORPHINE SULFATE PRE INJECTION, OCTREOTIDE, DEPOT FOR INJECTION, NALBUPHINE HCL, PER 1 INJECTION, MEPERIDINE HCL, PER 1 INJECTION, NANDROLONE DECANOATE, INJECTION, NANDROLONE DECANOATE, INJECTION, NANDROLONE DECANOATE, INJECTION, NESIRITIDE, 0.25 MG INJECTION, THIOTHIXENE, UP TO 4 INJECTION, NIACINAMIDE, NIACIN, INJECTION, CEPHALOTHIN SODIUM, U INJECTION, MOXIFLOXACIN, 100 MG INJECTION, HYOSCYAMINE SULFATE, INJECTION, DOBUTAMINE HCL, PER 2 INJECTION, PROPIOMAZINE, UP TO 2 INJECTION, LARONIDASE, 0.1 MG A INJECTION, FUROSEMIDE, UP TO 20 INJECTION, LEUPROLIDE ACETATE F INJECTION, LEVOCARNITINE, PER 1 INJECTION, LEVOFLOXACIN, 250 MG INJECTION, MEROPENEM, 100 MG INJECTION, METHOTRIMEPRAZINE, UP INJECTION, MEPERIDINE AND PROMET INJECTION, CHLORDIAZEPOXIDE HCL, INJECTION, LIDOCAINE HCL, 50 CC INJECTION, LIDOCAINE HCL FOR INT INJECTION, LINCOMYCIN HCL, UP TO INJECTION, LINEZOLID, 200 MG ZY INJECTION, LORAZEPAM, 2 MG ATIV INJECTION, MANNITOL, 25% IN 50 M INJECTION, OCTREOTIDE, NON-DEPOT INJECTION, LEVORPHANOL TARTRATE, INJECTION, FLUPHENAZINE DECANOAT Eff Dt 01 2003 Price $39.25 $4.37 $8.54 $3.06 $2.00 INVALID NC $6.03 INVALID $10.59 $5.18 INVALID $0.71 $49.40 $5.26 $9.44 $12.01 $208.59 $3.59 $3.46 $4.04 $8.07 $17.00 NC INVALID INVALID $0.01 $10.94 $11.05 $12.00 INVALID $28.15 $2.89 $614.09 $40.00 $22.83 $6.56 INVALID $0.01 $26.31 INVALID $0.78 $5.48 $42.74 $9.70 $1.21 $6.21 $3.96 $5.00 PAC 3.

However, the shortcomings of the trials make this conclusion provisional. Particularly having regard to the rather marked differences between levofloxacin and ofloxacin found in one case series see below ; it is unfortunate that the dose of levofloxacin used in the trial comparing it to ofloxacin was very low. The Cochrane reviewers did conclude that ciprofloxacin cannot be recommended in the treatment of tuberculosis. However, the clearly higher rate of relapse and treatment failure with ciprofloxacin was seen in only one trial, and is accounted for by only a small number of patients. Some useful information can be gathered from case series. The results are shown in Table 2. The case series selected for presentation here are those that are large, carefully studied, and offer information about the efficacy of fluoroquinolones as a class or one fluoroquinolone compared to another. Case series with follow-up too short to provide data on cure as an outcome eg, reference 8 ; have been excluded. It should be noted that all of these reports concern previously treated patients, rather than those with newly acquired MDR-TB, and that probably ; all the patients were HIV negative. In two series3, 5 patients were given a month's supply of treatment at a time and not supervised at all, and in another6 they were supervised only while they were in hospital usually as long as they were receiving parenteral aminoglycosides ; , and this compromises the applicability of the results to standard treatment conditions. The study of Yew and others has been widely quoted as demonstrating the superiority of levofloxacin over ofloxacin, and in its choice of drug doses, systematic use of DOT, and careful follow-up it is certainly the most relevant of the case series to optimal practice. However, the data covered many years, and there was a secular trend to increasing use of levofloxacin in later years, so that other factors may have been the cause of the apparent advantage associated with levofloxacin therapy and orlistat. One checklist is for community pharmacists to provide information to hospital pharmacists when such patients are admitted to hospital and another is for hospital pharmacists to provide information to community pharmacists when the patient is discharged. see appendix 7.

A knowledge of which countries prohibit or restrict travel by HIVinfected individuals is a necessary part of pre-travel preparations. Many countries either do not allow HIV-infected persons to enter or require some form of registration upon entry. Some require HIVantibody status to be tested within their country There is a relatively good correlation between CD4 counts and the risks of certain infections, as well as the risks for certain vaccines. The HIV-infected traveler should know his her CD4 status prior to making travel plans and be aware of the risks involved. Some live vaccines are absolutely contraindicated, while others are relatively contraindicated. see below ; Personal Protective Equipment Personal protective measures to reduce arthropod borne infections include insect repellents DEET ; , insecticides permethrin ; and wearing clothing that covers arms and legs. Sunscreens and broad-brimmed hats will protect against sun exposure. Frequent Travel - Related Infections The most frequent travel-related infections are enteric pathogens. Various types of enteric-pathogenic Escherichia coli are the most common. Others: Salmonella, Shigella, Campylobacter, Cyclospora, Cryptosporidium, Isospora species, Giardia intestinalis and Entamoeba histolytica. Except for the E. coli types, the HIV-infected traveler is at greater risk than the general population for severe infection and or serious complications, including extra-intestinal manifestations.

Background: Streptococcus pneumoniae is the leading cause of community-acquired pneumonia CAP ; . High global incidence of macrolide and penicillin resistance has been reported, whereas fluoroquinolone resistance is uncommon. Current guidelines for suspected CAP in patients with co-morbidity factors and recent antibiotic therapy recommend initial empiric therapy using one fluoroquinolone or one macrolide associated to other drugs amoxicillin, amoxicillin clavulanate, broad-spectrum cephalosporins ; . Resistance to fluoroquinolones is determined by efflux mechanisms and or mutations in the parC and parE genes coding for topoisomerase IV and or gyrA and gyrB genes coding for DNA gyrase. No clinical cases due to fluoroquinolone-resistant S. pneumoniae strains have been yet reported from Italy. Case presentation: A 72-year-old patient with long history of chronic obstructive pulmonary disease and multiple fluoroquinolone treatments for recurrent lower respiratory tract infections developed fever, increased sputum production, and dyspnea. He was treated with oral levofloxacin 500 mg bid ; . Three days later, because of acute respiratory insufficiency, the patient was hospitalized. Levoflxoacin treatment was supplemented with piperacillin tazobactam. Microbiological tests detected a S. pneumoniae strain intermediate to penicillin MIC, 1 mg L ; and resistant to macrolides MIC 256 mg L ; and fluoroquinolones MIC 32 mg L ; . Point mutations were detected in gyrA Ser81-Phe ; , parE Ile460-Val ; , and parC gene Ser79-Phe; Lys137-Asn ; . Complete clinical response followed treatment with piperacillin tazobactam. Conclusion: This is the first Italian case of community-acquired pneumonia due to a fluoroquinolone-resistant S. pneumoniae isolate where treatment failure of levofloxacin was documented. Molecular analysis showed a group of mutations that have not yet been reported from Italy and has been detected only twice in Europe. Treatment with piperacillin tazobactam appears an effective means to inhibit fluoroquinolone-resistant strains of S. pneumoniae causing community-acquired pneumonia in seriously ill patients.

The Optometric Practice and Licensure Act authorizes optometrists, who have been certified by the Board, to administer and prescribe legend and nonlegend drugs approved by the Secretary of Health. On October 10, 1998, the Pennsylvania Department of Health promulgated a regulation listing the drugs that could be used by optometrists. In October 2000, Secretary of the Commonwealth Kim Pizzingrilli, on behalf of the State Board of Optometry, requested that the Secretary of Health approve additional drugs for use by optometrists. In February 2001, Secretary of Health Zimmerman indicated that he would support an amendment to the Department of Health regulation that would add some of the drugs requested to the list of drugs that may be used by optometrists. The Department of Health is drafting the amendment. The proposed amendment must go through the rulemaking process. When the rulemaking becomes final, the following drugs will be available for use by optometrists: Quixin levofloxacin ; , Alamast pemirolast potassium ; , Emadine emedastine difumarate ; , Optivar azelastine hydrochloride ; , Zaditor ketotifen fumerate ; and Ultram tramadol ; . The Board will notify those licensees holding therapeutics certification when the rulemaking becomes final and those licensees may then begin using the new drugs. Bactericidal in a concentration-dependent manner though inhibition of bacterial DNA synthesis repair by interfering with DNA gyrase topoisomerase II ; and topoisomerase IV. Quinolones have excellent tissue and tissue fluid penetration so that they are suitable for infections in a wide range of organ systems. More Gram negative coverage: ciprofloxacin good Pseudomonas coverage ; and norfloxacin. These are often termed "urinary quinolones" as they do not have Streptococcus Pneumoniae coverage. Gram negative coverage with improved gram positive coverage: levofloxacin, moxifloxacin and gatifloxacin often termed "respiratory quinolones" ; . These agents are also effective against "atypical" pneumonia agents such as Mycoplasma, Chlamydia, and Legionella. Anaerobic coverage: moxifloxacin and to a lesser extent gatifloxacin neither agent covers C. difficile.

MRP inhibitor probenecid did not affect transcellular transport of grepafloxacin or levofloxacin Tables 2 and 3 ; . The organic cation cimetidine and organic anion p-aminohippurate had no influence on the transcellular transport or cellular accumulation of grepafloxacin or levofloxacin. In addition, the basolateral-to-apical transcellular transport of levofloxacin in the presence of cyclosporin A was decreased by unlabeled levofloxacin, grepafloxacin, and enoxacin, accompanied by increases in cellular accumulation Table 3 ; . Therefore, we considered that the transport of levofloxacin in Caco-2 cells was mediated by another transport system in addition to P-glycoprotein, distinct from organic cation and organic anion transporters and MRP. We reported that quinolones are specifically transported from the basolateral to the apical side in the kidney epithelial cell line LLC-PK1 by a specific mechanism and have higher affinity for the transport system on the apical membrane, a system distinct from the H organic cation antiport system and P-glycoprotein Matsuo et al., 1998 ; . In the present study, levofloxacin had higher affinity for the apical membrane in Caco-2 cells, because 1 mM levofloxacin inhibited the basolateral-to-apical transport, accompanied by increased accumulation Table 3 ; . The apparent Km value for saturable basolateral-to-apical transport of levofloxacin in the presence of cyclosporin A was 5.6 mM Fig. 5B ; , which was larger than the apparent Km of the saturable transcellular transport of levofloxacin reported using LLC-PK1 cells 0.6 mM ; Matsuo et al., 1998 ; . Therefore, it is likely that levofloxacin has lower affinity to the transport system in Caco-2 cells than in LLC-PK1 cells. It remains to be clarified whether the transport systems in these two cell lines are the same. Although the absorptive mechanisms were not fully evaluated in the present study, uptake of grepafloxacin from the apical membrane was greater than that from the basolateral membrane Fig. 3 ; . In contrast, uptake of levofloxacin from the basolateral membrane was greater than that from the apical membrane at time points before 5 min Fig. 3 ; . These results suggested that a specific transport system may contribute to the uptake of grepafloxacin from the apical membrane in Caco-2 cells. The precise mechanisms involved in uptake of quinolones remain to be clarified. In conclusion, our results suggest that gastrointestinal secretion of quinolone antibacterial drugs is mediated by P-glycoprotein and a specific transport system, which is distinct from organic cation and organic anion transporters and MRP. M. Mentasti, P. Morelli, G. Manno Genoa, IT ; Stenotrophomonas maltophilia Sm ; is an emerging pathogen in immunocompromised patients pts ; and frequently isolated from airway samples of cystic fibrosis cf ; pts. Often multiresistant, Sm is intrinsically resistant to carbapenems and virtually resistant to all b-lactams, but at present only CLSI breakpoints for levofloxacin L ; , minocycline M ; and trimethoprim sulfametoxazole TS ; are available. Agar dilution is the method recommended by CLSI to determine Sm antibiotic susceptibility pattern and E-Test AB BioDisk ; is described as a reliable alternative method. Objectives: This work is aimed to assess the reliability of discdiffusion with semi-automatic analysis by BioMIC Vision Giles Scientific Inc. ; and automated Phoenix System BD ; in Sm antibiotic susceptibility pattern determination, compared to ETest results. Methods: 70 non-repetitive Sm strains 38 from cf pts, 23 from nosocomial pts and 9 from nosocomial environment ; identified by API Z0NE and confirmed by species-specific amplification of 23S rRNA gene Whitby PW, 2000 ; , were tested by E-test and disc-diffusion on Mueller Hinton Agar 24 hours at 35C ; for L, M, TS, ceftazidime C ; , gentamicin G ; and ticarcillin clavulanate TC ; , and tested by Phoenix with NMIC ID-4 card containing C, G, L and TS. Sm ATCC 13637 and Escherichia coli ATCC 25922 were used as quality control strains. Discrepancies were classified as Very Major Error VME ; , Major Error ME ; and minor Error mE ; as described in NCCLS M23-A2 2000 ; . Results: MIN resulted active on all strains tested by E-test, followed by TS, L, TC, G and C. No discrepancy was detected between results of disc-diffusion with BioMIC Vision reading and E-Test for M and TS; for C, G and L 21 total mEs were detected, while for TC there were 6 VMEs. Phoenix generated 1 VME for L and 43 total MEs for C, G, L and TS.
