To better understand the global epidemiology of salmonellosis and the national surveillance programmes used for salmonella infections in humans, we conducted a global survey of the 191 WHO Member States. We gathered information on the total number of salmonella isolates serotyped, and the 15 most commonly isolated serotypes from humans in 1990 and 1995. Of the 104 countries that responded, 76 (...
فعالیت ضدباکتریایی (حداقل غلظت مهارکنندگی و کشندگی) عصاره آبی گزنه و مرزنگوش در مقابل 3 باکتری بیماریزا و عامل فساد مواد غذایی Escherichia coli, Salmonella typhi و Pseudomonasaeruginosa با استفاده از روش رقتلولهای(Macro Dilution Method) ارزیابی شد. مقدار حداقل غلظت بازدارندگی عصاره آبی مرزنگوش بر Salmonella typhi mg/ml 25/1 و در مورد Pseudomonas aeruginosaو Escherichia coli برابر با mg/ml 5 ...
A water snake (Natrix natrix) was referred to the Small Animal Teaching Hospital, Faculty of Veterinary Medicine, University of Tehran. It had two subcutaneous masses. Radiographic and ultrasonographic images revealed the presence of two subcutaneous abscesses. The abscesses were removed surgically and specimens were examined by conventional microbial culture and multiplex PCR. Inv-A universal ...
Salmonella enterica is a facultative intracellular pathogen that survives and proliferates in the Salmonella-containing vacuole (SCV), yet how these vacuolar bacteria acquire nutrition remains to be determined. Intracellular Salmonella convert the host endosomal system into an extensive network of interconnected tubular vesicles, of which Salmonella-induced filaments (SIFs) are the most promine...
Salmonella enterica serovar Typhimurium (Salmonella) is one of the most significant food-borne pathogens affecting both humans and agriculture. We have determined that Salmonella encodes an uptake and utilization pathway specific for a novel nutrient, fructose-asparagine (F-Asn), which is essential for Salmonella fitness in the inflamed intestine (modeled using germ-free, streptomycin-treated, ...
Salmonella is a facultative intracellular pathogen that causes a variety of infectious diseases. The most common of such diseases is gastroenteritis, with bacterial multiplication in intestinal submucosae and diarrhea, caused by the inflammatory response and perhaps also by toxins. In specific hosts, adapted salmonellae produce systemic diseases such as typhoid and paratyphoid fevers in humans....
The genus Salmonella was named after Daniel E. Salmon who first reported the isolation of Salmonella from a pig in 1885 and named the organism Bacterium choleraesuis (currently known as Salmonella enterica serovar Choleraesuis) [1,2]. Salmonella causes gastroenteritis and typhoid fever and is one of the major foodborne pathogens of significant public health concern [3]. Salmonella is considered...
Background and Objective: Salmonella typhi is one of the major challenges for the human and animal health. Salmonella with high pathogenicity can be harmful factor for human health. The control of this pathogen is a big challenge as it can cause serious infectious diseases such as gastroenteritis, septicemia and typhoid fever. On the other side, there are many factors such as toxin-antitoxin (T...
Salmonella spp. are important food borne pathogens worldwide that frequently infect poultry flocks. This cross-sectional study was conducted to determine the prevalence of Salmonella spp. colonization in broiler flocks in Shiraz (southern Iran) and to find the possible association of infection status with some potential risk factors including vaccination program and use of ant...
Background: Salmonella belongs to the family of Enterobacteriaceae, an intestinal, gram negative, and anaerobic bacterium. Salmonella affects a wide range of vertebrates, mainly through direct and indirect contact with the infected source. Salmonellosis is a dangerous infectious disease and a common human-animal disease. The integron (int) gene is effective in drug resistance and bacterial prol...
