Precisely knowing the stoichiometry of their components is critical for investigating structure, assembly, and function of macromolecular machines. This has remained a technical challenge in particular for large, hydrophobic membrane-spanning protein complexes. Here, we determined the stoichiometry of a type III secretion system of Salmonella enterica serovar Typhimurium using two complementary...
There is conflicting data regarding whether commercial chilling has any effect on persistence of Salmonella serovars, including antibiotic resistant variants, on chicken carcasses. A total of 309 Salmonella Typhimurium and Salmonella Kentucky isolates recovered from pre- and post-chill whole broiler carcasses were characterized for genetic relatedness using Pulsed Field Gel Electrophoresis (PFG...
The microbial quality of water that comes into the edible portion of produce is believed to directly relate to the safety of produce, and metrics describing indicator organisms are commonly used to ensure safety. The US FDA Produce Safety Rule (PSR) sets very specific microbiological water quality metrics for agricultural water that contacts the harvestable portion of produce. Validation of the...
زمینه و اهداف: سالمونلوزیس یکی از بیماریهای مهم عفونی و بهعنوان یک بیماری مشترک در انسان و حیوانات میباشد که اهمیت شناخت و کنترل اینگونه را ضروریتر میکند. ژنهای خانهدار، ژنهایی هستند که بهطورمعمول برای حفظ و بقای عملکرد سلولها ضروری میباشند و میتوانند بهعنوان ژنهای تشخیصی در غربالگری عوامل باکتریایی مدنظر قرار گیرند. هدف از این مطالعه بررسی ژنهای خانهدار fliC sdf1, و fljB برای...
Salmonella spp. are zoonotic enteric bacteria able to infect humans, livestock and wildlife. The aim of this study was to investigate the prevalence of Salmonella (spp.) and to determine antibiotic susceptibility, serogrouping and presence of invA gene (Salmonella Invasion Gene A) in the detected strains in wild captive herbivores in Iran. The fecal samples of 103 animals from 8 different speci...
