Introduction: Shiga toxin-producing Escherichia coli (STEC) strains are one of the main causes of food poisoning and diseases such as hemorrhagic colitis and hemolytic uremic syndrome.  Food contamination mainly occurs through food of animal origin such as meat and dairy products. The aim of this study was to investigate prevalence and distribution of virulence genes in Escherichia coli isolate...

Due to the genetic similarity of pathogenic Escherichia coli isolated from birds and pathotypes human origin, it is suggested that they have a common ancestor may exchange virulence-associated genes. This study aimed detect genes in E. strains Red-browed Amazon parrot (Amazona rhodocorytha) kept at conservation institute Brazil. High variability virulence was observed, since 12 profiles were fo...

Comprising a major clade of Anura, toads produce and secrete numerous toxins from both the parotoid glands behind their eyes dorsal skin. These toxins, made various proteins compounds, possess pharmacological potential to be repurposed benefit human health. However, detailed genetic regulation toad toxin production is still poorly understood. A recent publication uncovering genome representativ...

Clostridium difficile is a nosocomial pathogen that causes a serious toxin-mediated enteric disease in humans. Reducing C. difficile toxin production could significantly minimize its pathogenicity and improve disease outcomes in humans. This study investigated the efficacy of two, food-grade, plant-derived compounds, namely trans-cinnamaldehyde (TC) and carvacrol (CR) in reducing C. difficile t...

Fusarium head blight (FHB), mainly caused by graminearum, is one of the most devastating diseases wheat globally. FHB causes an extensive reduction in yield and reduces grain quality through its contamination with toxins such as deoxynivalenol (DON), T2 toxin, HT-2 nivalenol, zearalenone. This review provides overview updated progress genetic studies on resistance to FHB, emphasis sources gene/...

Cochliobolus heterostrophus race T, causal agent of southern corn leaf blight, requires T-toxin (a family of C35 to C49 polyketides) for high virulence on T-cytoplasm maize. Production of T-toxin is controlled by two unlinked loci, Tox1A and Tox1B, carried on 1.2 Mb of DNA not found in race O, a mildly virulent form of the fungus that does not produce T-toxin, or in any other Cochliobolus spp. ...
