BACKGROUND: Pseudomonas aeruginosa is an opportunistic and Gram-negative pathogen that is used as the most important factor in burn wound infections, and due to the rapid acquisition of multidrug resistance (MDR), it causes high mortality rates in these sectors. Thus, diagnosis and assessment of antibiotic resistance patterns are very important in these patients. The aim of this study was to evaluate antibiotic resistance pattern and determining P. aeruginosa MDR. MATERIALS AND METHODS: In this study, phenotypic, biochemical, and polymerase chain reaction tests were used to identify P...

The formation of metal chelates with various ligands may lead to the production of fluorescent chelates or enhance the fluorescence of the chelating agent. This paper describes two sensitive, selective and computer-solved methods, namely, zero order (SF) and second-derivative synchronous spectrofluorimetry (SDSFS) for nano-quantitation of two carbapenems; meropenem (MP) and ertapenem (EP). The methods are based on the chelation of MP with Tb(3+) and EP with Zr(4+) in buffered organic medium at pH 4.0 to produce fluorescent chelates...

Bacillus anthracis is considered a likely agent to be used as a bioweapon and use of a strain resistance to the first-line antimicrobial treatments is a concern. We determined treatment efficacy against a ciprofloxacin-resistant (C(r)) strain of B. anthracis (C(r) Ames) in a murine inhalational anthrax model. Ten groups of 46 BALB/c mice were exposed by inhalation to 7-35 LD50 of B. anthracis C(r) Ames spores. Commencing at 36 hours (h) post-exposure, groups were administered intraperitoneal doses of sterile water for injections (SWI) and ciprofloxacinalone (control groups), or ciprofloxacin combined with two antimicrobials including meropenem/linezolid, meropenem/clindamycin, meropenem/rifampin, meropenem/doxycycline, penicillin/linezolid, penicillin/doxycycline, rifampin/linezolid, or rifampin/clindamycin at appropriate dosing intervals(6 or 12 hours) for the respective antibiotics...

INTRODUCTION: Members of family Enterobacteriaceae are the most common Gram-negative bacteria isolated from clinical samples. Those Enterobacteriaceae which have acquired resistance to all β-lactams antibiotics including the carbapenems are considered as Carbapenem Resistant Enterobacteriaceae (CRE). These CRE isolates are often resistant to most other classes of antimicrobials as well, making their treatment a great challenge. Tigecycline is one of the last resort antimicrobials against such multidrug resistant bacteria...

BACKGROUND AND OBJECTIVE: Human in vitro and dog in vitro/in vivo researches indicate that the drug-drug interaction (DDI) of decreased plasma valproic acid (VPA) concentration by co-administration of carbapenem antibiotics is caused by inhibition of acylpeptide hydrolase (APEH)-mediated VPA acylglucuronide (VPA-G) hydrolysis by carbapenems. In this study, we investigated VPA disposition and APEH activities in TK-NOG chimeric mice, whose livers were highly replaced with human hepatocytes, to evaluate the utility of this animal model and the clinical relevance of the DDI mechanism...
