Enterotoxin-producing Clostridium perfringens type A isolates are an important cause of food poisoning and non-food-borne human gastrointestinal diseases, e.g., sporadic diarrhea (SPOR) and antibiotic-associated diarrhea (AAD). The enterotoxin gene (cpe) is usually chromosomal in food poisoning isolates but plasmid-borne in AAD/SPOR isolates. Previous studies determined that type A SPOR isolate...

background in recent decades, bacterial antibiotic resistance (especially in enterococci) has become a significant problem for human and veterinary medicine. one of the most important antibiotic resistances in enterococci, vancomycin resistance, is encoded by van gene family. objectives the aim of this study was to investigate antibiotic resistance to vancomycin in enterococci and the genes res...

The aim of the current study is to determine virulence genes E. faecalis and polymorphism in these bacteria. A total 300 females who visited outpatient clinics Maternity Pediatrics Teaching Hospital Al-Diwaniya city, Iraq were enrolled. For twenty isolates that showed dense growth when cultured on specified culture media, then sensitivity antibiotics was tested, determined for each isolate, whe...

Listeria monocytogenes is a gram-positive, intracellular, food-borne pathogen capable of causing severe infections in immunocompromised or pregnant individuals, as well as numerous animal species. Genetic analysis of Listeria pathogenesis has identified several genes which are crucial for virulence. The transcription of most of these genes has been shown to be induced upon entry of Listeria int...

Background: Escherichia coli (E. coli) remains one of the leading agents of urinary tract infection (UTIs), it has become resistant to many drugs. Current work aimed to evaluate some chemical substances as antibacterial agents and molecular study of virulence factors associated with UTIs. Methods: This work involved 133 urine specimens obtained from females’ patients suffering from UTIs, Met...

European grapevine, Vitis vinifera , carries no major resistances against Plasmopara viticola the causal agent of grapevine downy mildew. The introgression quantitative trait loci conferring resistance to P. ( Rpv ) from American and Asian donor species has resulted in a range resistant cultivars. In light perennial nature high evolutionary potential durability this is an important challenge. D...

Aspergilloses are fungal diseases in humans and animals that is caused by members of the genus Aspergillus. Aspergillus flavus is an important opportunistic pathogen, second only to A. fumigatus as a cause of human aspergillosis. Differences in virulence among A. flavus isolates from clinical and other substrates and mating types are not well known. The fruit fly Drosophila melanogaster has bec...
