A total of 2582 non-duplicate clinical Acinetobacter spp. isolates were collected to evaluate the performance of four identification methods because it is important to identify Acinetobacter spp. accurately and survey the species distribution to determine the appropriate antimicrobial treatment. Phenotyping (VITEK 2 and VITEK MS) and genotyping (16S rRNA and rpoB gene sequencing) methods were a...

OBJECTIVES The purpose of this study is to compare the antimicrobial activity of linezolid and tigecycline with other commonly used antibiotics against a variety of clinical isolates at Royal Hospital, Muscat. METHODS Clinically-significant bacterial isolates in Royal hospital during the period from 1st of March to 30th of June 2007 were collected, stored and finally tested to determine their...

INTRODUCTION Acinetobacter spp. have emerged as notorious pathogens involved in healthcare-associated infections. Carbapenems are important antimicrobial agents for treating infections due to multidrug resistant Acinetobacter spp. Different mechanisms may confer resistance to these drugs in the genus, particularly production of class D carbapenemases. OXA-23-like family has been pointed out as ...

Endophytic and plant-associated bacteria were isolated from plants and rhizoplane soil of naturally grown Brachiaria grasses at International Livestock Research Institute in Nairobi, Kenya. Eighty-four bacterial strains were isolated from leaf tissues, root tissues, and rhizoplane soil on nutrient agar and 869 media. All bacterial strains were identified to the lowest possible taxonomic unit us...

A surveillance study was performed in four Singapore public hospitals from 2006 to 2008 to determine the correlation between antibiotic prescription and Gram-negative bacterial antimicrobial resistance. Targeted organisms included ceftriaxone- and ciprofloxacin-resistant Escherichia coli and Klebsiella pneumoniae, as well as imipenem-resistant Pseudomonas aeruginosa and Acinetobacter spp. Antib...

aims: the internal unit and icu of hospitals are a suitable environment for growing of bacteria such as staphylococcus epidermidis and pseudomonas, acinetobacter. the aim of our study was to evaluate the effect of different disinfectants on bacteria isolated from the surface of hospitals in isfahan. instrument & methods: in this study, 200 samples were randomly selected from different parts of ...

Rods of the Acinetobacter genus are present mainly in the external environment (e.g. water, soil) and in animals, while in humans they may comprise physiological flora. The main pathogenic species is Acinetobacter baumannii complex, which constitutes a common cause of nosocomial infections, particularly in patients with underlying diseases and risk factors (e.g. prior broad-spectrum antibiotic ...

War wound infection and osteomyelitis caused by multidrug-resistant (MDR) Acinetobacter species have been prevalent during the 2003-2005 military operations in Iraq. Twenty-three soldiers wounded in Iraq and subsequently admitted to our facility from March 2003 to May 2004 had wound cultures positive for Acinetobacter calcoaceticus-baumannii complex. Eighteen had osteomyelitis, 2 burn infection...

The in-vitro activity of colistin sulphomethate sodium was compared with that of other commonly used antimicrobial agents against 377 recent clinical isolates of Gram-negative bacteria (including 94 strains of Pseudomonas aeruginosa from patients with cystic fibrosis) and 16 organisms with defined resistance patterns. Colistin was active against most strains of P. aeruginosa (MIC90 4 mg/L), Shi...

We determined the occurrence of acquired metallo-b-lactamase (MBL)-producing bacteria in Korean hospitals. Among the isolates nonsusceptible to imipenem that were collected from 28 hospitals from 2000 to 2001, 44 (11.4%) of 387 Pseudomonas spp. and 38 (14.2%) of 267 Acinetobacter spp. produced MBL and had alleles of blaVIM-2 or blaIMP-1. MBL-producing isolates were detected in 60.7% of the hosp...
