OBJECTIVE A bloodstream infection (BSI) is a life-threatening condition. We studied the causative agents of BSIs and antimicrobial susceptibility patterns of bacterial isolates at Muhimbili National Hospital (MNH) in Dar es Salaam, Tanzania. METHODS A retrospective analysis of blood culture results obtained at MNH from January 2005 to December 2009 was done. Blood culture isolates judged to b...

A four-center study in which a total of 1,082 recent clinical isolates of members of the family Enterobacteriaceae and Pseudomonas aeruginosa were examined versus 11 antimicrobial agents with the bioMérieux Vitek susceptibility test system (Hazelwood, Mo.) and the GNS-F6 card was conducted. In addition, a challenge set consisting of the same 200 organisms was examined in each of the four partic...

background and objectives: there is increasing emergence of multidrug resistant pseudomonas aeruginosa (mdrpa) strains and drug resistance is positively-correlated with biofilm-forming ability. since about 10% of p. aeruginosa genome is controlled by quorum sensing (qs), alteration in its antibiotic susceptibility by targeting qs was the focus of the present study. materials and methods : one d...

conclusions: it can be concluded that most of a. baumannii isolates can form biofilm in microtiter plate and tube. the results also verified that most of these isolates were resistant to ciprofloxacin and imipenem. results: results showed that in tube method under shaking, 22% of clinical isolates were strong biofilm producers while 23% of them were not able to form biofilms. in this experiment...

The aim of this retrospective study was to create guidelines for therapy of severe sepsis in surgical intensive care unit (ICU) for unknown causative agent based on antimicrobial susceptibility of causative bacteria. Seventy-four patients with severe sepsis from surgical ICU in 2003.-2005. were included in study. Their clinical and microbiological data were analyzed from the medical records. An...

introduction: escherichia coli (e.coli) as a main cause of both nosocomial and community-acquired infections in humans have a relative potential to develop resistance. nowadays, most infections caused by esbl-producing e.coli (esblec) had mostly been described as nosocomial acquired or nursing home related. in this study, we employed e-test assay to detect antibiotic resistance of e.coli strain...

background: anopheles mosquitoes are an important group of arthropods due to their role in transmission of ma­laria. the present study was conducted for determination of susceptibility status of anopheles stephensi to different imagicides collected from malarious area in chabahar city, iran. methods: in the present study seven insecticides including: ddt 4%, lambdacyhalothrin 0.05%, deltamethri...

background and objectives: blood stream infections cause significant morbidity and mortality in the world. in this study, we aimed at describing the organisms responsible for septicemia in 2006-2007 and their antimicrobial susceptibility that might lead to proper selection of antimicrobial agents in hospitalized patients with suspected sepsis. materials and methods: microbiology reports of 1753...

In recent years, the high frequency of fungal infections originating from Candida and dermatophyte strains has accelerated treatment attempts. Antimicrobial susceptibility test for poly (AN-co-VP) / copolymer, which we think could be an ideal drug in interventions was evaluated with disk diffusion method minimum inhibitor concentration. antimicrobial measurement data, it determined that coolyme...

The fully automated microbial system, RAISUS (Nissui Pharmaceutical, Tokyo, Japan) can provide antimicrobial susceptibility test results for the isolates of Haemophilus influenzae. It is known that viable cell concentrations (colony forming unit/ml) of H. influenzae significantly vary depending on the incubation period. For the rapid reporting of antimicrobial susceptibility test results, we ev...
