Two molecular biology methods were used to differentiate Salmonella enterica 1,4,[5],12:i:- strains: "Salmonella Check&Trace microarray" (CT) and multiplex PCR (mPCR). For 92 strains in CT result "Salmonella 1,4,[5],12:i:-" were obtained. Those strains were confirmed in mPCR as monophasic fljB-lack Salmonella Typhimurium. For 17 strains, which in CT assay were recognized as Salmonella Typhimuri...

background :    salmonellosis is an infectious and a food-borne disease of humans and animals. the initial source of the infection is the intestinal tracts of birds and other animals. apparently healthy animals can become subclinical carriers and persistently shed salmonella in their feces which can act as a reservoir for the pathogen. the aim of this study is to detect the carriers of salmonel...

background and objective : salmonellosis can be acquired through consumption of infected raw or undercooked eggs. the aim of this study was isolation and identification of salmonella spp from the eggshells and the egg contents samples of tabriz retails. methods : a total number of 150 samples of eggs were analyzed for the presence of salmonella spp. using conventional culture method and multipl...

Background: Salmonella is the most important source of food-borne infections around the world. Human salmonellosis is also found in fresh fruit and vegetable salads. Objective: to investigate detection of Salmonella spp.,  in Hamburger, Vegetable salads and Cream-filled pastries from factories, supermarkets, restaurants and local confectionery, Mazandaran, Iran, as well as, to assess their pat...

Background: Salmonella, a bacterial genus of more than 2500 serotypes is considered as the most significant foodborne pathogen causing infections in humans and animals. Increased antimicrobial resistance and persistence of antimicrobial residues in food matrices warrants the need for alternative infection management strategies. Aims: The present study aimed to isolate and evaluate the lytic act...

cockroaches were collected from hospitals, houses and poultry sheds in various parts of isfahan (iran) and identified to species. in total, seven species of cockroaches in seven genera were identified: blatta lateralis, polyphaga aegyptiaca, arenivaga roseni and parcoblatta spp. three species periplaneta americana, blattella germanica and supella longipalpa (blattidae and blattellidae) were mor...

The effects of antibiotic, probiotic, and prebiotic as dietary feed additives on carcass composition as well as Salmonella counts and its serotypes in droppings and intestine of broiler chickens on days 1, 28, and 56 of experiment were investigated. Dietary treatments were control diet (basal diet without additives), OXYT diet (basal diet with 600 ppm of the antibiotic oxytetracycline), GRO-UP ...

Background and Objective: Salmonellosis is an important infectious zoonotic disease that makes it even more significant to identify and control the causative strains. Molecular methods, especially polymerase chain reaction (PCR), for virulence genes can help to quickly and accurately identify Salmonella strains. Accordingly, the purpose of this study was molecular identification based on sivH, ...

Dry heat was used to inactivate Salmonella newington, Salmonella typhimurium, Salmonella anatum, Salmonella kentucky, Salmonella cubana, Salmonella seftenberg, Salmonella thompson, and Salmonella tennessee in corn flour at 10 and 15% moisture. The flour was spray inoculated at 10(5) Salmonella cells per g and then stored at 49 degrees C (120 degrees F); viable Salmonella cells were counted on T...
