Colistin resistance in Acinetobacter spp. is increasing, resulting potentially untreatable nosocomial infections. Plasmid-mediated colistin of particular concern due to its low fitness cost and potential transferability other bacterial strains species. This study investigated the mechanism a clinical nosocomialis isolate from Cape Town, South Africa. A colistin-resistant A. was identified blood...

During the years 1994 to 1998, 10 strains of Salmonella enterica serovar Enteritidis phage type 11 (PT11) and 6 PT9a strains were isolated from Danish hedgehogs, together with 7 strains that did not yield phage susceptibility patterns conforming with any known phage type (routine dilution no conformity [RDNC]). From 1995 to 1998, five Danish patients were reported infected with serovar Enteriti...

Molecular characterization (e.g., DNA-based typing methods) of Salmonella isolates is frequently employed to compare and distinguish clinical isolates recovered from animals and from patients with food-borne disease and nosocomial infections. In this study, we compared the abilities of different phenotyping and genotyping methods to distinguish isolates of Salmonella enterica serovar Typhimuriu...

Salmonella enterica serovar Rissen has been recognised as a common serovar in humans and pigs around the world. This study investigated S. Rissen prevalence in pigs slaughtered in Northern Ireland additionally looking at antibiotic susceptibility profiles, genetic profiles and plasmid profiles to provide information on an emerging non-typhoid Salmonella serotype with the potential to cause dise...

Forty-seven Salmonella Typhimurium (33 zoonotic, 14 clinical) strains were tested for antimicrobial resistance using the standard disk diffusion method. Presence of relevant resistance genes and class 1 integrons were investigated by using PCR. Pulsed-field gel electrophoresis (PFGE) and plasmid profiling were carried out to determine the genomic diversity of Salmonella Typhimurium. Approximate...

the biodegradation of secondary amines is particularly important due to their propensity for conversion either chemically or microbiologically to n-nitrosamines which are potent carcinogens. in this research, a weak gram-positive organism was isolated from river and identified as mycobacterium. this mycobacterium grows slowly and effectively utilizes piperazine as the sole source of organic, ca...

The widespread use in urological practice of biological and artificial materials, on the surface which bacterial biofilms form, increases risk pathogen persistence human body. Nowaday, there is an acute problem catheter-associated urinary tract infections (САUTI), are most commonly caused by uropathogenic Escherichia coli (UPEC) strains, either monoculture as part polymicrobial associations wit...

In order to evaluate the genetic variability of the causative agent of cold water disease (CWD), plasmid profiling was used to characterize Flavobacterium (F.) psychrophilum isolates (n = 169). Size analysis of plasmids in F. psychrophilum isolates (n = 128) from several fish species demonstrated that six kinds of plasmids were harbored, and ayu isolates had different profiles compared to other...
