Two cases of documented osteoarticular infections caused by Kingella kingae in children are reported. The main bacteriological characteristics and antibiotic susceptibilities of these two isolates are described. The pathology of K. kingae, particularly in bones and joints, is reviewed.

In vitro antibiotic susceptibilities were determined for 101 strains of salmonellae. Resistance to chloramphenicol and ampicillin was low. Cefamandole was active against the majority of strains and deserves further evaluation.

The objective of this study was to evaluate collateral sensitivity and cross-resistance antibiotic-induced resistant Salmonella Typhimurium various antibiotics. S. ATCC 19585 (STWT) exposed ciprofloxacin, gentamicin, kanamycin, tetracycline induce antibiotic resistance, respectively, assigned as STCIP, STGEN, STKAN, STTET. susceptibilities the mutants cefotaxime, chloramphenicol, polymyxin B, s...

INTRODUCTION This retrospective study was performed to evaluate the frequency of anaerobic bacteraemia over a 10-year period, and to provide updated antibiotic susceptibilities for the more clinically relevant anaerobes causing blood stream infection. MATERIALS AND METHODS Data were retrieved from the laboratory information system for the period 2003 to 2012. During this time, blood cultures ...

Pharmacodynamic analyses were proposed to determine optimal empirical antibiotic therapy against Gram-negative bacteria isolated in a Brazilian ICU. Due to high resistance rates, standard regimens of cefepime, ciprofloxacin, meropenem, and piperacillin/tazobactam were not able to attain significant bactericidal CFR. Prolonged infusion of meropenem achieved 88% CFR, making it a possible empirica...

We describe a rare case of anterior paramediastnial abscess due to Nocardia cyriacigeorgica in an immunocompetent patient without pre-existing lung disease. High suspicious should be taken in those patients that failed to improve after first course of antibiotic therapy. Similarly, when suspected, isolation is crucial because of the variation in antibiotic susceptibilities among Nocardia spp. i...
