BACKGROUND Nowadays, the treatment of burned patients is difficult because of the high frequency of infection with antibiotic resistance bacteria. OBJECTIVES This study was conducted to evaluate the level of antibiotic resistance in Gram-negative bacteria and its relation with the existence of plasmid. MATERIALS AND METHODS The samples were collected from two hundred twenty hospitalized bur...

Outer surface protein C (OspC) is the most studied major virulence factor of Borrelia burgdorferi, the causative agent of Lyme disease. The level of OspC varies dramatically among B. burgdorferi strains when cultured in vitro, but little is known about what causes such variation. It has been proposed that the difference in endogenous plasmid contents among strains contribute to variation in Osp...

The aim of the study was to investigate the characteristics of Salmonella serotype Enteritidis strains isolated from outbreaks and sporadic cases in Turkey by plasmid profiles and randomly amplified polymorphic DNA (RAPD) patterns. A total of 64 S. Enteritidis clinical strains were selected from the culture collection of the Enterobacteria Laboratory of Ankara University Medical School Departme...

A number of amino acid requiring auxotrophic strains of Salmonella Typhimurium were produced by chemical mutagenesis. One of them, strain 81, was cured of the virulence plasmid and attenuated for mice. This strain had an auxotrophic requirement for serine, which could be used as a marker for the differentiation of the vaccine strain from other isolates in the field. The strain still contained t...

The aim of the present study was to analyze and compare Borrelia strains isolated from two different specimens obtained simultaneously from individual patients with Lyme borreliosis. Fifty such patients and 50 corresponding pairs of Borrelia isolates (100 low-propagated strains) were subjected to genotypic and phenotypic analysis, including pulsed-field gel electrophoresis for species identific...

Pseudomonas aeruginosa GW-1 was isolated in 2000 in South Africa from blood cultures of a 38-year-old female who developed nosocomial pneumonia. This isolate harbored a self-transferable ca. 100-kb plasmid that conferred an expanded-spectrum cephalosporin resistance profile associated with an intermediate susceptibility to imipenem. A beta-lactamase gene, bla(GES-2), was cloned from whole-cell ...

This study was carried out to evaluate the plasmid mediated drugs resistance among wound bacteria isolates obtained from (352 swabs specimens) patients attending some hospitals in Kano State (National Orthopaedic Hospital Dala, Aminu Teaching Hospital, Infectious Diseases Bichi General and Wudil Hospital). Swab specimens were aseptically using randomized sampling method cultured on Blood MacCon...

Electrophoretic techniques were employed to study variation in chromosomal genes encoding enzymes and in the distribution of cryptic plasmids in the E. coli population of a human host over an 11-month period. Thirteen of the 15 enzymes studied were polymorphic, and mean genetic diversity per locus was 0.39. Among 550 clones isolated from fecal samples, protein electrophoresis revealed 53 distin...

the present study aimed to evaluate the antibiotic resistance pattern of escherichia coli strains isolatedfrom animals to ascertain the levels of antibiotic resistance pervasiveness. a total of 28 e. coli strains wereisolated from faecal samples and the antibiotic resistance pattern of e. coli strains was determined by meansof disc diffusion assay. the resistance pattern determined for all stra...
