OBJECTIVE To determine the frequency of capsular serotypes and the antimicrobial susceptibility of strains of Streptococcus pneumoniae, as well as to provide recommendations on the use of available vaccines and antimicrobial drugs. METHODS In this retrospective study, standard procedures were followed to identify, serotype, and determine bacterial susceptibility to penicillin, cefotaxime, and...

In the last years an increase in the anaerobes resistance has een worldwide reported1,2; however, most studies only refer to acteroides fragilis group and antibiotic susceptibility data of other enus are limited. Although reasons that may lead to failure of herapy include lack of surgical drainage or poor source control, as ell as patient’s comorbidities and poor penetration and low levls of an...

staphylococcus aureus is a major bacterial pathogen that causes different community- and hospital-acquired infections. over time, strains of s. aureus have become resistant to different antibiotics including penicillinase-resistant penicillins. having data on the local antimicrobial susceptibility pattern of this pathogen is necessary for selection of appropriate antibiotics for empirical treat...

Resistance of Streptococcus pneumoniae to antimicrobial drugs is increasing. To investigate the relationship between antimicrobial use and susceptibility of S. pneumoniae isolates at 24 U.S. medical centers, we obtained data on outpatient antimicrobial-drug use for the regions surrounding 23 of these centers. We found an association between decreased penicillin susceptibility and use of beta-la...

The aim of this study was to isolate, identify and determine the antimicrobial susceptibility of (CP) isolates from acute necrotic enteritis of broiler chickens. All carcasses diagnosed as necrotic enteritis (NE) were sampled, subjected to microbial tests and 40 isolates were identified according to standard procedures. The antimicrobial susceptibility of CP isolates to 20 antibacterial agents ...

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 Bloodstream infections (BSIs) are the major cause of mortality in cancer patients. Molecular techniques are used for rapid diagnosis of BSI, allowing early therapy and improving survival. We aimed to establish whether real-time quantitative polymerase chain reaction (qPCR) could improve early diagnosis and therapy in paediatric cancer patients, and describe the predominant pathogens ...
