An efficient workflow to screen for and confirm the presence of carbapenemase-producing Gram-negative bacilli was developed by evaluating five chromogenic screening agar media and two confirmatory assays, the Rapid Carb screen test (Rosco Diagnostica A/S, Taastrup, Denmark) and the modified Hodge test. A panel of 150 isolates was used, including 49 carbapenemase-producing isolates representing ...

Coagulase-negative staphylococci (CoNS) represent an important etiology of nosocomial bloodstream infections (2, 4, 6). The introduction of empirical treatment has been a crucial step in reducing morbidity and mortality caused by such infections and in controlling the spread of resistant strains (1, 6). It has been advocated that the cefoxitin disk would be more sensitive than the 1g oxacillin ...

Background: Vancomycin has been widely used in the treatment of infections caused by Methicillin-Resistant Staphylococcus Aureus (MRSA). The emergence of VancomycinIntermediate and -Resistant Staphylococcus Aureus (VISA and VRSA, respectively) in various parts of the world has been of great concern in clinical settings. Objective: This study was performed to evaluate the possible presence of VI...

This study was conducted to determine antibiotic susceptibility of Flavobacterium psychrophilum isolated in diseased rainbow trout (Oncorhynchus mykiss) from two hatcheries the Mediterranean region Turkey. The samples were taken kidney and spleen for bacteriology juveniles (weight 0.7-1 g) April isolates obtained on tryptone yeast extract salts (TYES) agar medium at 15°C 72 hours. Fourteen iden...

INTRODUCTION S. aureus is one of the main agents of nosocomial infection and is sometimes difficult to treat with currently available active antimicrobials. PURPOSE To analyze the prevalence of methicillin-susceptible S.aureus (MSSA) and methicillin-resistant S. aureus (MRSA) as well as the MRSA antimicrobial susceptibility profile isolated in the saliva of health professionals at a large pub...

BACKGROUND Selective chromogenic media allowing one-step meticillin-resistant Staphylococcus aureus (MRSA) isolation and identification are widely used. However, the changing epidemiology of MRSA means that the suitability of these chromogenic media requires investigation. AIM To evaluate the following chromogenic media - Colorex MRSA, MRSA Select II, ChromID MRSA, and MRSA Brilliance 2 - for...

AZD2563, a novel oxazolidinone, and a selection of comparator drugs that included linezolid, erythromycin, clindamycin, quinolones, and gentamicin were tested against 384 Staphylococcus aureus (176 oxacillin-resistant S. aureus [ORSA]) and 219 coagulase-negative staphylococci (CoNS; 162 oxacillin resistant) by reference microdilution (all strains) and agar dilution (30 strains) methods. The fol...

BACKGROUND Staphylococcus aureus has a notable ability to acquire resistance to antibiotics, and methicillin resistance represents a growing public health problem. Methicillin-resistant S. aureus (MRSA) has also become important outside the hospital environment, particularly in the United States. In Brazil, since 2005, cases of community skin infections caused by MRSA have been reported, but re...
