Streptococcosis has been defined as a hemorrhagic septicemia in many fish species especially rainbow trout. This disease causes serious economic losses due to high mortality in fish and the bacteria responsible is also considered as a zoonotic pathogen. The aim of this study was identification of different causative agents of warm water streptococcosis and evaluation of the capsule gene in Lact...

The reproduction of single egg-mass isolates of Meloidogyne javanica from Crete that differed in virulence were compared on tomato (Lycopersicon esculentum) genotypes homozygous or heterozygous for the Mi gene. The reproduction of three isolates with partial virulence was much greater on tomato genotypes heterozygous for the Mi gene (cultivars Scala, Bermuda, and 7353) than on two homozygous ge...

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...

The aim of this research is to estimate the virulence factor L. major exosome by real time gene expression. higher expression in footpad tissue was (29.34), day seven culture (20.37), twelve (12.25), highest line control (8.33). current work revealed that elevated comparison cultures media. levels were passage three and lowest one, level declined with progress time.

A one hundred and twenty specimens (frozen chickens) were gathered from various companies sources at sites in Iraq. the aim of this study to detect virulence gene isolated Ecoli frozen chicken meat shops Iraq investigate distribution antibiotics resistance against papC E coli. The result shows that( n,%) 15, 45 ,33,100, 2,6 , 20, 60.6 26,78.7 % out 33 isolate positive for pap C gene, jutA neuC ...

Bacterial fruit blotch (BFB) caused by Acidovorax citrulli is a worldwide threat to watermelon and melon production. The type III secretion system (T3SS) plays an important role in the virulence of A. its host plants induce hypersensitive response (HR) non-host plants. Little known, however, about contribution T3SS biofilm formation . We mutated two T3SS-related genes hrcJ hrpE , respectively, ...

Abstract The current study included the investigation of E. coli bacteria in random samples ground meat, detection virulence genes isolates, and isolates resistance to some widely used antibiotics. Twenty-four minced meat were collected isolate identify by phenotypic, microscopic characteristics traditional biochemical tests done. Antibiotic susceptibility tests, genomes extracted, factors Stx1...

The occurrence and distribution of clinically relevant bacterial virulence genes across natural (non-human) environments is not well understood. We aimed to investigate the occurrence of homologs to bacterial human virulence genes in a variety of ecological niches to better understand the role of natural environments in the evolution of bacterial virulence. Twenty four bacterial virulence genes...
