Fifty-four clinical isolates of "Acinetobacter anitratus" separated cleanly into gentamicin-susceptible (16 strains) and gentamicin-resistant (38 strains) subpopulations. When tested with a 10(4)-CFU inoculum, gentamicin resistance was associated with a greater than fourfold increase in the MICs of norfloxacin, ciprofloxacin, A-56620, tobramycin, and amikacin for 50% of the strains. Antimicrobi...

In this study, the serogroup and susceptibility patterns of Shigella and Salmonella spp. isolated from stool cultures were determined using standard laboratory procedures. Among the 76 Shigella isolates serogroup B (Sh. flexeneri) was the most prevalent species (54.0%) and among the 37 Salmonella strains serogroup B was also the most prevalent (81.1%). Antibiograms of Shigella and Salmonella sp...

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 ...

Present study investigated the antibiotic resistance profile of bacterial strains isolated from soil, sediment and waters of Eloor-Edayar Industrial belt of Kerala, South India. A total of 165 bacterial strains were isolated and tested for their sensitivity to 11 common antibiotics (Ampicillin, Erythromycin, Gentamycin, Nalidixic acid, Penicillin, Vancomycin, Novobiocin, Amikacin, Kanamycin, St...

Antibiotic resistance in Enterococcus species causing clinical disease was examined in a point-prevalence study in 2005. Twenty-two sites around Australia collected up to 100 consecutive isolates and tested them for susceptibility to ampicillin, vancomycin, high-level gentamicin and/or high-level streptomycin using standardised methods. Results were compared to similar surveys conducted in 1995...

BACKGROUND Wound infections have been a problem in the field of surgery for a long time. Advances in control of infections have not completely eradicated this problem because of development of drug resistance. Antimicrobial resistance can increase complications and costs associated with procedures and treatment. OBJECTIVE A study was carried out on drug sensitivity patterns of bacterial isola...

pseudomonas aeruginosa is one of the most important pathogens that causes nosocomial infections and shows high level of antibiotic resistance. integrons are one of the transposable elements in bacteria and their role in antibiotic resistance has been well demonstrated. the aim of this study was a molecular characterization of the integron genes and the determination of the resistance or sensiti...

BACKGROUND & OBJECTIVES This study was carried out to evaluate the association between the antibiotic susceptibility patterns and the antibiotic resistance genes in staphylococcal isolates obtained from various clinical samples of patients attending a teaching hospital in Hatay, Turkey. METHODS A total of 298 staphylococci clinical isolates were subjected to antimicrobial susceptibility testi...

Since the early 1970s, the synergistic activity of an aminoglycoside with a cell wall-active agent has been predicted by determining the ability of an enterococcus to grow in the presence of high levels of the aminoglycoside (usually > or = 2,000 micrograms/ml). However, a variety of media and concentrations of aminoglycosides has been used for this screening procedure. In the present study, we...

This study aimed to compare the antibiogram phenotype and carriage of antimicrobial resistance genes (ARGs) of 97 porcine multidrug-resistant (MDR) enterotoxigenic Escherichia coli (ETEC) isolates obtained from Vietnam and 117 porcine MDR-ETEC obtained from Australia, two countries with different antimicrobial regulation systems. An antimicrobial resistance index (ARI) was calculated to quantif...
