background uropathogenic escherichia coli (upec) is a causative agent of most of urinary tract infections (utis), which expresses a multitude of virulence factors. objectives the aim of this study was to investigate virulence associated characteristics characteristics in upec isolates derived from urine specimens, and to investigate the distribution of the pathogenicity islands virulence marker...

conclusions antibiotic resistance gene cassettes may be carried on integron or other genetic elements. the purpose of this study was to detect integron or genomic islands involved in antibiotic resistance profile of the isolates of h. influenzae collected in this study. results of the twenty isolates, all (100%) were resistant to clindamycin, chloramphenicol and tetracycline, 95% to amoxicillin...

UNLABELLED IGIPT is a web-based integrated platform for the identification of genomic islands (GIs). It incorporates thirteen parametric measures based on anomalous nucleotide composition on a single platform, thus improving the predictive power of a horizontally acquired region, since it is known that no single measure can absolutely predict a horizontally transferred region. The tool filters ...

The prevalence of different antimicrobial resistance profiles and variants of the Salmonella genomic island 1 (SGI1) was reported for Salmonella enterica serovar Typhimurium DT104 strains isolated from patients in Denmark. Variation in antimicrobial resistance and corresponding changes of SGI1 were shown among isolates from a foodborne outbreak.

Six out of the 64 studied Proteus mirabilis isolates from 11 poultry farms in China contained Salmonella genomic island 1 (SGI1). PCR mapping showed that the complete nucleotide sequences of SGI1s ranged from 33.2 to 42.5 kb. Three novel variants, SGI1-W, SGI1-X, and SGI1-Y, have been characterized. Resistance genes lnuF, dfrA25, and qnrB2 were identified in SGI1 for the first time.

Submit Manuscript | http://medcraveonline.com B .pseudomalleus is capable of infecting almost anything because of the spectacular genetic structure, by possessing certain genomic island (GIs) that gives the ability to alteration and to adapt. The genes of this GIs play an important role in pathogenesis ability. Trains which cause disease in humans differ from those causing disease in other anim...

Pseudomonas extremaustralis 14-3b presents genes involved in the synthesis of different polyhydroxyalkanoates, in tolerance and degradation of pollutants, and in microaerobic metabolism. Several genomic islands were detected. Genetic machinery could contribute to the adaptability to stressful conditions. This is the first genome sequence reported from a Pseudomonas isolated from cold environments.

To investigate the presence and structure of AbaR-type genomic islands (GIs) in non-Acinetobacter baumannii isolates, a total of 155 non-baumannii Acinetobacter isolates from a South Korean hospital were analyzed. GIs were found in three Acinetobacter nosocomialis and two Acinetobacter seifertii isolates. Their structures were similar to those in A. baumannii isolates from Asian countries, incl...

UNLABELLED A Genomic Islands (GI) is a chunk of DNA sequence in a genome whose origin can be traced back to other organisms or viruses. The detection of GIs plays an indispensable role in biomedical research, due to the fact that GIs are highly related to special functionalities such as disease-causing GIs - pathogenicity islands. It is also very important to visualize genomic islands, as well ...
