INTRODUCTION Pseudomonas aeruginosa and Acinetobcter spp. are important nosocomial pathogens and carbapenem resistance is an emerging threat. Therapeutic options for infections with these isolates include colistin. This study was conducted to determine the prevalence of carbapenem resistance in P. aeruginosa and Acinetobacter spp. bloodstream isolates, phenotypically characterize the resistance...

Background Acinetobacter are gram negative, catalase positive, oxidase negative, nonmotile, non fermenting cocobacilli. The emergence of Acinetobacter infection is uncommon in organ systems that have a high fluid content. The nosocomial infections including, respiratory tract, CSF, peritoneal fluid, urinary tract, and endotracheal aspirtes (ET) are the place where they have the capabilities to ...

OBJECTIVES The goal of this study was to investigate the epidemiological characteristics and the surrounding genetic structure of bla(NDM-1) in non-baumannii Acinetobacter spp. in China. METHODS Non-baumannii Acinetobacter spp. were collected from 28 provinces in China and were screened for the presence of bla(NDM-1) using PCR. The following four methods were used to classify the Acinetobacte...

Carbapenem-resistant Pseudomonas aeruginosa, Acinetobacter spp., and Enterobacteriaceae pose urgent public health threats. The differential burden, relative risks, associations with antimicrobial consumption, and temporal trends of those taxa in large, geographically diverse U.S. health systems remain under reported. Electronic records of all patients in a geographically dispersed 280-hospital ...

Acinetobacter spp. occur naturally in many different habitats, including food, soil, and surface waters. In clinical settings, Acinetobacter poses an increasing health problem, causing infections with limited to no antibiotic therapeutic options left. The presence of human generated multidrug resistant strains is well documented but the extent to how widely they are distributed within the Acine...

BACKGROUND AND PURPOSE To detect and characterize class 1 integrons among carbapenem-resistant strains of Acinetobacter spp. at University Malaya Medical Centre (UMMC), Kuala Lumpur, Malaysia. METHODS Thirty nine carbapenem-resistant Acinetobacter strains were obtained from UMMC from August 2003 to March 2004 and analyzed for the presence of bla(IMP) genes and class 1 integrons. RESULTS Cla...

The rising incidence of Acinetobacter infection in the intensive care unit (ICU) causes a great concern to all clinicians and intensivists worldwide due to their extraordinary ability to develop resistance to multiple classes of antibiotics. Acinetobacter can infect virtually any body site, particularly the lower respiratory tract, the bloodstream, and the urinary tract. Infection is mainly rel...

background: acinetobacter spp., as important opportunistic pathogens, have been found to be responsible for an increas­ing number of nosocomial infections. this study was undertaken to investigate the antimicrobial susceptibility and molecular typing of iranian isolates of a. baumannii . methods: the study was conducted over a period of 19 months in three hospitals in tehran, iran. acinetobacte...

Acinetobacter spp. are gram-negative aerobic coccobacilli that are ubiquitous in nature, persistent in the hospital environment, and cause a variety of opportunistic nosocomial infections (Bergogne-Berezin et al, 1996). They cause various types of human infections. Of the currently known 31 Acinetobacter species, Acinetobacter baumannii is the most prevalent in clinical specimens. A number of s...
