Abstract Purpose Staphylococcus aureus ( S. ) is the most important pathogen involved in bovine mastitis dairy production. produces a spectrum of extracellular protein toxins and virulence factors which are thought to contribute pathogenicity organism. The aim this work was isolate molecular characterize associated with subclinical central part Ethiopia. Methods A total 265 lactating cows from ...

Lactic acid bacteria (LAB) are a diverse group of microorganisms that can be found in natural habitats and used wide range industries, especially the food sector. They regarded "Generally Recognized as Safe" commonly starter culture, probiotics, biopreservative. However, some LAB genera excluded from "Qualified Presumption Safety" (QPS) list due to possibility they have virulence antibiotic res...

Objective: Considering the emergence of biofilm-associated pathogens with multidrug resistance, the objective(s) of the present study was to evaluate the anti-virulence property of Syzygium aromaticum extracts/fractions against 2 multidrug-resistant catheter isolates. Materials and Methods: Pulverized clove buds were subjected to bioactivity-guided isolation to identify the bioactive extract/fr...

background and objectives: streptococcus pneumoniae, a major human pathogen, is closely related to the commensal species s. mitis and s. oralis. s. pneumoniae surface proteins are implicated in virulence and host interaction of this species, but many of them have recently been detected in s. mitis b6 in silico. we tested for the presence of such genes usinga set of eight s. mitis and eleven s. ...

background: colibacillosis is one of the most prevalentdiseases in the world that causes multimillion-dollar annuallosses. objectives: in order to evaluate molecular epidemiologyof some virulence associated factors in escherichia coli,isolated from poultry, the presence of iut a, iss, hly f, omp t, iron, afa, sfa (s)and pap g (ii) were investigated by multiplex pcrassay. methods: two hundred th...

conclusions these findings illustrated the presence and persistence of clonal groups of mrsa strains, in chicken meat in isfahan, iran, that serve as reservoirs to disseminate bacteriophage encoded enterotoxin and virulence agents. results all 116 isolated mrsa strains were discriminated into seven php types consisting of seven common types (cts) and were positive for meca gene. all isolates ha...

The identification of virulence genes in plant pathogenic fungi is important for understanding the infection process, host range and for developing control strategies. The analysis of already verified virulence genes in phytopathogenic fungi in the context of integrated functional networks can give clues about the underlying mechanisms and pathways directly or indirectly linked to fungal pathog...
