Colonization of the human and animal intestinal tract with potential pathogenic bacteria is correlated with the risk of contamination of food products. The current study analyzed the prevalence of Enterococcus faecalis and Escherichia coli O157H7 in ground meat in Ilam, Iran. Both index organisms were identified following standard food microbiological methods. For E. faecalis, the susceptibilit...

This study was conducted at Karbala governorate through the months of November 2021 until March 2022. Total number 240 sampling carried out from street vender and local store (milk, yogurts cheese) cow buffalo. These samples were collected different locations in Iraqi province. Escherichia coli O157H7 serotype prevalence rate buffalo major focus this research conducted. 120 products with region...

Cytotoxic and antimicrobial effects of Montivipera xanthina venom against LNCaP, MCF-7, HT-29, Saos-2, Hep3B, Vero cells and antimicrobial activity against selected bacterial and fungal species: Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, E. coli O157H7, Enterococcus faecalis 29212, Enterococcus faecium DSM 13590, Staphylococcus epidermidis ATCC 12228, S. typhimirium CCM 5445...

conclusions etec and eaggec were the most detected e. coli among stool and uti samples, emphasizing the need to dedicate more health care attention to this group. in addition, our phylogenetic study may be helpful in figuring out the infection origin and for epidemiological studies. nonetheless, more research studies with larger sample sizes are suggested for confirming our results. results ove...

enterohemorrhagic escherichia coli (ehec) of the o157:h7 serotype is a worldwide zoonotic pathogen responsible for the majority of severe cases of human ehec disease. the aim of the present study was to investigate the prevalence of e. coli o157: h7/nm in raw meat samples from two provinces of iran. during a period from march 2010 to march 2011. two hundred and ninety five raw meat samples were...

background: extended spectrum beta lactamases (esbls) are an important cause of transferable multidrug resistance (mdr) in gram-negative bacteria. the most described esbl genes are generally found within integron-like structures as mobile genetic elements. the aim of this study was to identify the accompanying of class 1 integrons and esbls in the mdr e. coli isolates. methods: susceptibility t...

background and objectives: diarrheagenic escherichia coli (dec) is an emerging agent among pathogens that causes diarrhea. studies showed that diarrheagenic e. coli such as enterohaemorrhagic e. coli (ehec), enteroaggregative e. coli (eaec), enteropathogenic e. coli (epec), enteroinvasive e. coli (eiec), enterotoxigenic e. coli (etec), diffusely adhering e. coli (daec) and shiga toxin producing...

background: leukemia inhibitor factor (lif) is a very important pleiotropic cytokine which belongs to interleukin-6 (il-6) family. lif exerts multiple effects on different types of cells and tissues with numerous regulatory effects in vivo and in vitro. it is a lymphoid factor, which performs a number of activities including cholinergic neuron differentia­tion, control of stem cell pluripotency...

conclusions: e. coli herb-resistance plasmid can replicate and be expressed in s. aureus. results: the identified 45 kb herb-resistance plasmid could be transferred from e. coli cp9 isolates to e. coli dh5α. as a consequence e. coli dh5α transconjugant mic increased from 0.0125 g/ml to 0.25 g/ml. the plasmid was easily transferred from e. coli cp9 strain to s. aureus rn450rf with a mean transfe...
