Background and Objectives: Salmonella spp. are one of the most important zoonotic agents with a worldwide distribution. Asymptomatic cats which may excrete Salmonella. spp for weeks can play important role in environmental contamination. The aim of this study was to access the role of rural cats in dissemination of Salmonella. spp. Methods: Salmonella excretion was evaluated in 170 samples (...
Poultry meat has been identified as one of the principal foodborne sources of Salmonella. In this preliminary study the prevalence of Salmonella spp. and its typhimurium serovar contamination of broiler carcasses, were determined. Using the rinse test method, numbers of 60 samples, representing 20 broiler flocks, were collected from poultry carcasses after the chilling stage in the processing l...
Sampling techniques to detect airborne Salmonella species (spp.) in two pilot scale broiler houses were compared. Broilers were inoculated at seven days of age with a marked strain of Salmonella enteritidis. The rearing cycle lasted 42 days during the summer. Airborne Salmonella spp. were sampled weekly using impaction, gravitational settling, and impingement techniques. Additionally, Salmonell...
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 cephalosporins are increasing in pre...
OBJECTIVE To estimate prevalence of fecal shedding of Salmonella spp among horses in the US horse population and prevalence of Salmonella spp in grain or other concentrate used as horse feed on equine operations in the United States. DESIGN Cross-sectional survey. SAMPLE POPULATION Horses on 972 operations in 28 states. PROCEDURE Fecal samples were collected from horses resident at each o...

Captive reptiles are routinely identified as reservoirs of Salmonella spp. and reports of reptile-associated salmonellosis are increasing. Unfortunately, little is known about the epidemiology of Salmonella spp. and green iguanas. We did a limited survey of a green-iguana farm in El Salvador to identify sources of Salmonella spp. in green iguanas and their environment. A limited number of sampl...
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...
plant essential oils are natural products extracted from plants and because of their antimicrobial properties can be used as natural additives in foods. they are also useful for decontamination of food-borne pathogens and can be a safe additive in foods. the antimicrobial activities of essential oils belonging to saturiea hortensis, thymus vulgaris, mentha polegium, cuminum cyminum, lavandula o...
The survival of Salmonella spp. as pathogen indicator in composting was studied. The inoculums technique was used to gives the known amounts of Salmonella spp. involved in composting. The inoculums of Salmonella spp. solution was added directly into the compost material. The direct inoculum was compared with inoculums in vial technique. The Salmonella spp. solution placed into a vial and insert...
