AIM This work was conducted to study the phenotypic and genotypic characterization of locally isolated Salmonella strains (Salmonella Pullorum, Salmonella Enteritidis, and Salmonella Typhimurium) from poultry used in the preparation of Salmonella antigens in Egypt. MATERIALS AND METHODS The phenotypic characterization of Salmonella strains was done using standard microbiological, biochemical,...

background: salmonella is one of the causes of food-borne illnesses worldwide resulting in a wide range of human diseases. the aim of this research was to study molecular epidemiology and antimicrobial resistance of salmonella spp. isolated from resident patients in mazandaran province, northern iran. methods: totally, 51 stool samples were collected from patients in 20 outbreaks recorded in he...

conclusions our results indicate that acetylation genes have an important role in aminoglycoside resistance of the enterococcus isolates from clinical samples. moreover, salmonella strains indicate very low level of aminoglycoside resistance, and aminoglycoside resistance genes were not found in salmonella isolates. these results indicate that other resistance mechanisms, including efflux pumps...

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...
