Bacterial human virulence genes across diverse habitats as assessed by in silico analysis of environmental metagenomes

Frontiers in Microbiology, 2016
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 homologues to bacterial human virulence genes in a variety of ...

Comparative genome analysis of 24 bovine-associated Staphylococcus isolates with special focus on the putative virulence genes [PDF]

PeerJ, 2018
Non-aureus staphylococci (NAS) are most commonly isolated from subclinical mastitis. Different NAS species may, however, have diverse effects on the inflammatory response in the udder. We determined the genome sequences of 20 staphylococcal isolates from

BSA-Seq Discovery and Functional Analysis of Candidate Hessian Fly (Mayetiola destructor) Avirulence Genes

Frontiers in Plant Science, 2020
The Hessian fly (HF, Mayetiola destructor) is a plant-galling parasite of wheat (Triticum spp.). Seven percent of its genome is composed of highly diversified signal-peptide-encoding genes that are transcribed in HF larval salivary glands.

Distribution of Virulence Factors in Vancomycin-Resistant Enterococci Isolated from Clinical and Intestinal Samples

Microorganisms
Virulence factors in enterococci play an important role in the pathogenesis of enterococcal infection and colonization. The aim was to determine the prevalence of genes encoding virulence factors in VRE from clinical and intestinal samples.

Occurrence of virulence genes in multidrug-resistant Escherichia coli isolates from humans, animals, and the environment: One health perspective.

PLoS ONE
Escherichia coli is one of the critical One Health pathogens due to its vast array of virulence and antimicrobial resistance genes. This study used multiplex PCR to determine the occurrence of virulence genes bfp, ompA, traT, eaeA, and stx1 among 50 ...

MOLECULAR IDENTIFICATION OF Aeromonas hydrophila STRAINS RECOVERED FROM KAFRELSHEIKH FISH FARMS

Slovenian Veterinary Research, 2019
The aim of this study was to recover Aeromonas hydrophila from Kafrelsheikh tilapia (Oreochromis niloticus) farms and to study its virulence. Adult fish (n = 100) exhibiting the onset of clinical signs were bacteriologically examined using aeromonas ...
