The aims of this study were to develop multiplex PCR for simultaneous detection of five superantigenic toxin genes (sea, seb, sec, sed and tst-1) in Staphylococcus aureus isolated from 149 clinical samples and nasal swabs from 201 healthy subjects in Thailand, and to compare prevalence and expression of those genes between methicillin-resistant S. aureus (MRSA) and methicillin-sensitive S. aure...

This study was aimed to investigate diverse stress treatments on Imipenem susceptible A. baumannii for persister cells formation. Isolates were assessed presence by colony forming unit counting (CFU/ml) after exposure (10 µg/ml) in and absence of acid treatment (pH 6) 0-7 hr. In- vitro activity curcumin synergize kill investigated. The frequency hicAB relEB type II toxin- antitoxin (TA) loci ev...

the present work was conducted to compare the occurrence of escherichia coli possessing virulence and esbl genes in backyard and farmed poultry. three hundred and sixty samples from the poultry kept in backyard system and 120 samples from the farmed birds were collected from west bengal, india. among the e. coli isolates of backyard poultry (o2, o10, o25, o55, o60, o106, ut), none of them posse...

HC-toxin is a cyclic tetrapeptide of structure cyclo(D-Pro-L-Ala-D-Ala-L-Aeo), where Aeo stands for 2-amino-9,10-epoxi-8-oxodecanoic acid. It is a determinant of specificity and virulence in the interaction between the producing fungus, Cochliobolus carbonum, and its host, maize. HC-toxin qualifies as one of the few microbial secondary metabolites whose ecological function in nature is understo...

the aim of this study was to determine the presence of toxin genes in clostridium perfringens isolated from 200minced meat samples using molecular typing. for this purpose, after isolation of clostridium perfringens using conventional culture method and confirmation by specific 16srd na gene pcr, alpha (cpa), beta (cpb), beta 2 (cpb2),epsilon (etx), iota (ia) and enterotoxin (cpe) genes were in...

The aim of this study was to determine the frequency of enterotoxigenic and enteroaggregative strains ofEscherichia coli in chicken carcasses by polymerase chain reaction (PCR). In this study 63 strains of E. coliwere isolated from 110 samples of chicken carcasses during processing after chilling in the poultry slaughterhouse of Shahrekord. Polymerase chain reaction assays were used to detect t...
