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...

The purpose of this study was to survey infections with Salmonella spp. in poultry flocks in the vicinity of Tehran and to determine the most frequent serogroups and serotypes implicated. Twenty-eight samples of pullet, layer, and broiler flocks were randomly collected (n=1463), including freshly dropped feces from live birds or visceral organs from dead birds. In most flocks, 60 samples were t...

  Background: and Objectives: Salmonella infections are endemic in many developing countries with poor sanitary conditions, but emerge sporadically as a serious public health threat in developed countries. Infections with multidrug resistant (MDR) strains of Salmonella have been associated with treatment failures. Salmonella spp. resistant to extended spectrum cephal...

Background: Salmonella spp. is one of the most common pathogens associated with fresh produce related foodborne illness. This study aimed to determine Salmonella spp. contamination level in betel leaf, internalization potential and possible decontamination process. Results: A total of 77% betel leaf sample collected from local market was found to be contaminated with Salmonella spp. Of all the ...

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...

The Wellcolex Colour Salmonella Test was evaluated for detection of Salmonella spp. in enrichment broths of 1,010 stool samples. In 39 specimens, Salmonella spp. could be isolated from the selenite F broth (SF). Wellcolex agglutination indicative of the presence of Salmonella spp. was noted with the SF in 36 cases, 34 of which were in agreement with the subculture results. Therefore, relative 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 antibiotics. during o...

PCR DNA amplification of a region of the himA gene of Salmonella typhimurium specifically detected Salmonella spp. In oysters, 1 to 10 cells of Salmonella spp. were rapidly detected by the PCR following a pre-enrichment step to increase sensitivity and to ensure that detection was based on the presence of viable Salmonella spp.

background: salmonella enterica serovar typhi, as causative agent of typhoid fever, is one of the most important endemic pathogens. non-typhoidal salmonella serovars, including typhimurium , infantis , and enteritidis are amongst the most prevalent serotypes worldwide and in developing areas such as iran. the aim of this study was to apply a uniplex pcr for rapid detection of salmonella spp., a...

Aim: Salmonellosis is one of the most common zoonotic diseases, and the presence of antimicrobial resistant Salmonella in wild birds is global public health threat. Throughout the last decades, multidrug resistance of Salmonella spp. has increased, particularly in developing countries. Therefore, a cross-sectional study was conducted to investigate the prevalence of Salmonella spp. and antimicr...
