Abstract Staphylococcus aureus is a prevalent bacterial causative agent of bovine mastitis and human food illness by secreting enterotoxins. This study aims to identify the seven classic enterotoxin genes (SEA SEH) isolated from humans animals. A total 173 isolates 14 (goat cow) were amplified with 23S rRNA genes. The presence classical enterotoxins (sea-seh) was using multiplex polymerase chai...

background and objectives: brucella, causative of brucellosis, has some potential virulence factors involved in brucella replication and its strategies to circumvent the immune response. one of them is the virb gene that encodes the type іv secretion system proteins (t4ss) involved in intracellular replication of organism. brucella virulence factor a ( bvf a), and urease ( ure ) has also been d...

conclusions the trat gene and pai markers were highly prevalent among upec strains isolated from patients in kashan, iran; therefore these determinants could be used as targets for prophylactic interventions. also there was a high level of resistance against the antibiotics commonly used for urinary tract infection treatment. to reach better therapeutic outcomes, treatment regimens have to be m...

Calcineurin, which functions in calcium signaling, is expressed in skeletal and cardiac muscle and has been linked to sensitivity to muscle strength training. It is also proposed to contribute to individual aerobic endurance. To investigate the relationship between calcineurin-encoding genes and aerobic endurance traits, 126 young-adult Han Chinese males were enrolled in an aerobic exercise tra...

conclusions our study demonstrated that the b1 gene, more so than the re gene, showed positive samples and can be used to detect toxoplasmosis, although the b1 gene, in comparison to the re gene, did not show any superiority of molecular diagnosing capability. results also showed that toxoplasma molecular detection methods can be used instead of routine serological detection methods in a clinic...

The aim of this study was to determine the occurrence of enterotoxigenic and enteroaggregative Escherichia coli strains and antibiotic resistance of the isolates in raw milk and unpasteurized cheese. Out of 200 samples of raw milk and 50 samples of unpasteurized cheeses, 96 and 24 strains of E. coli were isolated, respectively. Polymerase chain reaction (PCR) was used to detec...

Members of the 14-3-3 protein family are involved in many important cellular events, including stress response, survival and apoptosis. Genes of the 14-3-3 family are conserved from plants to humans, and some members are responsive to UV radiation. Despite the high rate of pollution generated by nano-pollutants, up to now is totally obscure their toxic effect on development. Embryos treated wit...

Salmonella is one of the most important zoonotic pathogens with many virulence factors playing a major role in its pathogenesis. The aims of this study were to detect spvA, int2 and invC virulence genes of different Salmonella serotypes isolated from various clinical animal and human sources, and to investigate antibiotic resistance patterns among these serotypes. Using a PCR assay, a total of ...

Background: Several virulence factors have been described in pathogenesis of Staphylococcus aureus strains. Staphylococcal Enterotoxins(SEs) that is one of the most factors, are belonging to important members of bacterial superantigens. Superantigens are defined by their ability to stimulate cytokine release from both T cells and macrophages. 13 different SEs are known that their function is no...
