objective: escherichia coli (e.coli) o157:h7 is one of the most important pathogenic causes of hemorrhagic colitis in humans. cattle are the main reservoirs of this bacteria and vaccination is a key mechanism for its control. the intimin, translocated intimin receptor (tir), and espa proteins are virulence factors expressed by the lee locus of enterohemorrhagic e. coli. espa protein is a member...

Echium amoenum Fisch. and C.A. Mey. (Boraginaceae) is a very popular medicinal plant which is used as a tonic, tranquillizer, diaphoretic, cough remedy, sore throat and pneumonia in Iran’s traditional medicine. Callus culture of medicinal plants is one of the ways for production of secondary metabolites. In this study, callus culture of E. amoenum and its major secondary metabolite were investi...

Phaseolus vulgaris represents a great source of nutrit io n fo r millions of people, and is the second most important legume crop, after soybean. Assessment of environmental contamination on e cology (plant) at molecular and population levels is important in risk quantification and remediation s tud y . Heavy metal toxicity in plants is to induce o xidative s tress linked to oxidation of protei...

BACKGROUND Recent malaria vector control measures have considerably reduced indoor biting mosquito populations. However, reducing the outdoor biting populations remains a challenge because of the unavailability of appropriate lures to achieve this. This study sought to test the efficacy of plant-based synthetic odor baits in trapping outdoor populations of malaria vectors. METHODOLOGY AND PRI...

The currently available anthrax vaccines are limited by being incompletely characterized, potentially reactogenic and have an expanded dosage schedule. Plant based vaccines offer safe alternative for vaccine production. In the present study, we expressed domain IV of Bacillus anthracis protective antigen gene [PA(dIV)] in planta (by nuclear agrobacterium and chloroplast transformation) and E. c...

For two large beef processing plants, one located in the southern United States (plant A) and one located in the northern United States (plant B), prevalence of Escherichia coli O157:H7, Listeria spp., Listeria monocytogenes, and Salmonella was determined for hide, carcass, and facility environmental samples over the course of 5 months. The prevalence of E. coli O157:H7 (68.1 versus 55.9%) and ...
