Background: Lactococcus garvieae causes lactococcosis in rainbow trout in many parts of the world. Aims: This study was conducted for the existence of the virulent factors and differentiation of the two serotypes in L. garvieae. Methods: Twenty-two strains of L. garvieae isolated from diseased rainbow trout from farms...

Background and Aims: Acinetobacter baumannii is mostly a cause of septicaemia, pneumonia and urinary tract infections following hospitalization of patients with more severe illnesses. The aim of this study was to determine the prevalence and detection of the most prevalent virulence genes in A. baumannii isolated from hospital infections of two largest hospitals of Tehran, Iran. Materials and ...

conclusions our results show the presence of clonal groups of enterotoxin-producing mrsa strains in this hospital in tehran. the presence of bacteriophage encoded virulence factors and resistance to oxacillin enable bacteria to produce a broad spectrum range of diseases. results out of the 279 s. aureus isolates, 91 (32.6%) strains were confirmed as mrsa. totally, 6 enterotoxin and 2 virulence ...

Introduction: Toxigenic Clostridium difficile is the major cause of antibiotic-associated diarrhea, colitis, and pseudomembranous colitis. The pathogenicity of C. difficile is related to toxins A&B. Children with cancer are at risk of developing C. difficile infection (CDI) due to increased exposure to antibiotics, immunosuppression, and longer hospital stays. Recently, due to higher sensitivity...

conclusions these results indicate that the pcr method is a powerful genotypic assay for the detection of adhesin-encoding operons. thus, this assay can be recommended for clinical use to detect virulent urinary e. coli strains, as well as epidemiological studies. materials and methods a total of 100 upec isolates were obtained from urine samples of patients with uti. the prevalence of 5 virule...

Powdery mildew is a common, economically important disease in the wheat growing area of Serbia. A large-scale virulence survey its causal agent Blumeria graminis f. sp. tritici population was performed period 1995–2013. total 1013 isolates were recovered from collected chasmothecial samples. Among them, 862 unique pathotypes identified using differential set 20 lines with known powdery (Pm) res...

Objective(s): The enteroaggregative Escherichia coli (EAEC) has been one of the most intriguing emerging bacterial pathogens in children that occur both in developing countries and the industrial world. Although various phenotypic and genotypic based protocols have been suggested for diagnosis of EAEC, they are not conclusive or practical to be used in most clinical la...
