background: infectious by pseudomonas aeruginosa has spread worldwide and metallo-beta-lactamases (mbl) are being reported with increasing frequency. the aim of this study was to investigate the antibiotic susceptibility and distribution of blavim and blaimp genes in p. aeruginosa isolates from zanjan province of iran. methods: a total of 70 p. aeruginosa isolates were identified from patients ...

Methicillin-resistant coagulase-negative staphylococci were isolated from the nares and skin of 1- to 8-week-old healthy chickens in three flocks from a farm. Isolation of methicillin-resistant coagulase-negative staphylococci was positive for 72 (25.7%) of the 280 chickens tested, with the frequency varying from 2.2 to 100% according to flock. A total of 45 appropriate isolates were selected a...

Of a total of 1043 macrolide-resistant Streptococcus pneumoniae isolates collected from 24 countries as part of PROTEKT 1999-2000, 71 isolates tested positive for both the mef(A) and erm(B) genes. Of 69 isolates subjected to further molecular investigations, all were resistant to tetracycline, 63 (91.3%) were resistant to penicillin, and 57 (82.6%) were resistant to trimethoprim-sulfamethoxazol...

INTRODUCTION Due to the emergence of drug-resistant pneumococcal isolates, new fluoroquinolones have been recommended for the treatment of pneumococcal infections. The purpose of this study was to establish surveillance, and to conduct molecular characterization, of fluoroquinolone-resistant Streptococcus pneumoniae in Seville. METHOD Norfloxacin-resistant S. pneumoniae isolates were characte...

Campylobacter jejuni is one of the most common bacterial causes of human gastroenteritis, and recent findings suggest that turkeys are an important reservoir for this organism. In this study, 80 C. jejuni isolates from eastern North Carolina were characterized for resistance to nine antimicrobials, and strain types were determined by fla typing, pulsed-field gel electrophoresis (PFGE) with SmaI...

conclusions all the bacterial isolates were associated with a high resistance to various antibiotics and this resistant pattern could be confirmed by detection of a particular gene for each bacterium. objectives this study examined bacteremia in cancer patients from two medical centers regarding isolates and spectrum of antibiotic resistance pattern. patients and methods this was a prospective ...

This report presents the prevalence of Palestinian isolates of methicillin-resistant Staphylococcus aureus (MRSA) in nosocomial infections and their antibiotic resistant pattern. A total of 321 clinical isolates of S. aureus were identified from different patients. The prevalence of methicillin resistance among S. aureus isolates was 8.7% (28 isolates). Resistance rates of MRSA to other antibio...

background: metronidazole is drug of choice recommended by who for treatment of trichomoniasis, however, some reports claims drug resistance in trichomonas vaginalis isolates recently. the objective of this study was to determine the minimum lethal concentration (mlc) of metronidazole in resistant and sensitive strains, as well as genetic patterns of these stains by pcr method. methods : from f...
