Anaerobic bacteria have pivotal roles in the microbiota of humans and they are significant infectious agents involved in many pathological processes, both in immunocompetent and immunocompromised individuals. Their isolation, cultivation and correct identification differs significantly from the workup of aerobic species, although the use of new technologies (e.g., matrix-assisted laser desorpti...

BACKGROUND Difficult-to-treat infections caused by rapidly growing mycobacteria (RGM) are increasingly observed in clinical settings. However, studies on antimicrobial susceptibilities and effective treatments against RGM in Japan are limited. METHODS We conducted susceptibility testing of potential antimicrobial agents, including tigecycline and tebipenem, against RGM. Clinical RGM isolates ...

The disc diffusion, Etest and agar dilution techniques were compared to evaluate the antimicrobial susceptibility profile of 70 Stenotrophomonas maltophilia isolates to seven antimicrobial agents. The S. maltophilia isolates were consecutively collected from May 2000 to May 2002 from individual patients, who were hospitalized in a private Brazilian hospital. The antimicrobial susceptibility tes...

background enterococci have emerged as more virulent and multidrug-resistant in community and hospital settings. the emergence of vancomycin resistant enterococci (vre) in hospitals has posed a serious threat to public health. the widespread use of antibiotics to treat vre infections has resulted in the development of resistant forms of these organisms. conclusions among the nanoparticles, zno ...

BACKGROUND & OBJECTIVES Reliable methods of detection of antimicrobial resistance are of paramount importance in the treatment and management of infections caused by Haemophilus influenzae. The objective of the present study was to compare and evaluate the performance of disc diffusion and E test (Epsilometer test) with agar dilution method for antimicrobial susceptibility testing of H. influen...

INTRODUCTION The Clinical and Laboratory Standards Institute (CLSI) updated its antimicrobial susceptibility testing interpretation criteria for Enterobacteriaceae. This study assessed the effects of clinical breakpoint changes in the CLSI 2009 to 2012 guidelines on antibiotic susceptibility testing reports. METHODOLOGY In total, 2,076 non-duplicate clinical isolates of Enterobacteriaceae wer...

abstract       background and objective: due to the continuous increase of multidrug-resistant acinetobacter baumannii strains around the world, decision making for an effective treatment of infections caused by this organism depends on the results of antimicrobial susceptibility tests. in this study, the validity of disk diffusion and e-test methods was assessed by their comparison with the re...

BACKGROUND Urinary tract infections (UTIs) are common in dogs. The responsible bacterial populations have evolved with increasing resistance to many antimicrobials. OBJECTIVE To characterize the antimicrobial susceptibility patterns of canine urinary tract isolates over a 51-month period. ANIMALS One thousand six hundred and thirty-six bacterial isolates from 1,028 dogs. METHODS Aerobic b...
