The aim of this study was to determine the frequency and allele associations of locus of enterocyte effacement encoded esp and tir genes among 181 enteropathogenic Escherichia coli (EPEC) strains (90 diarrhoea-associated ...

The present study evaluated the presence of 10 genes encoding various virulence factors of biological importance in 100 Salmonella Typhimurium isolates, where 90 isolates came from sick guinea pigs and 10 from apparently ...

The biogenesis of the plant mitochondrial respiratory chain needs the coordinated synthesis and assembly of the products of more than 100 genes located in the nucleus and within the organelle. One of the factors that ...

The present report is the original description of blaTEM-176. The mechanisms of resistance to antimicrobial agents were determined in an enterotoxigenic Escherichia coli, determining the susceptibility to 22 antimicrobials ...

A recently described clinical isolate, “Candidatus Bartonella ancashi,” was obtained from a blood sample of a patient presenting with verruga peruana in the Ancash region of Peru. This sample and a second isolate obtained ...

There are increasing evidences that horizontal gene transfer (HGT) is a critical mechanism of bacterial evolution, while its complete impact remains unclear. A main constraint of HGT effects on microbial evolution seems ...

Diarrhoeagenic Escherichia coli (DEC) are an important cause of diarrhoea in children and are associated with high antibiotic resistance. However, there are few studies on the molecular mechanisms of resistance in this ...

In the postgenome era many efforts have been dedicated to systematically elucidate the complex web of interacting genes and proteins. These efforts include experimental and computational methods. Microarray technology ...
