Salmonella enterica subsp. enterica serovar Typhimurium var. Copenhagen isolates from a heifer-raising operation and from 11 dairy herds that had their calves contracted to the heifer-raising operation were examined for their phenotypic and genotypic characteristics. Results of the study showed that the heifer-raising operation could serve as a clearinghouse for Salmonella serovar Typhimurium v...
Salmonella enterica subsp. enterica serovar 1,4,[5],12:i:- is a monophasic variant of Salmonella Typhimurium, which has recently been recognized as an emerging cause of infection worldwide. This bacterium has also ranked among the four most frequent serovars causing human salmonellosis in China. However, there are no reports on its contamination in Chinese food. Serotyping, polymerase chain rea...
AIM The aim was to clone and sequence hfq gene of Salmonella Typhimurium strain PM-45 and compare its sequence with hfq gene of other serovar of Salmonella. MATERIALS AND METHODS Salmonella Typhimurium strain PM-45 was procured from the G. B. Pant University of Agriculture and Technology, Pantnagar, India. The genomic DNA was isolated from Salmonella Typhimurium. Hfq gene was polymerase chain...
Salmonella Typhimurium has been reported to contaminate egg production across the world, but where Salmonella Enteritidis is endemic it is this latter serovar that dominates egg-borne salmonellosis. However, Salmonella Typhimurium is a major food-borne pathogen so it is important to understand how it can impact the microbiological safety of eggs and what serovar-specific control strategies may ...
The prevalence, among human clinical cases, of Salmonella enterica serotype 4,5,12:i:-, a serotype antigenically similar to Salmonella enterica serotype Typhimurium but lacking second-phase flagellar antigens, has increased considerably over the last 10 years. To probe the evolution and ecology of this emerging serotype, we characterized 190 Salmonella isolates initially classified as Salmonell...
Since the early 1970’s a number of large Salmonella outbreaks have been associated with low aw food products, including chocolate, cereal, peanut butter, spices, and powdered infant formula. This research is design to help the food industry to determine Salmonella survival in the production environment and thus understand the potential risk of cross contamination to the product. The studies sou...
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 (S.) Typhimurium and S. Enteritidis are the major causative agents of food-borne illnesses worldwide. Currently, a rapid detection system using multiplex real-time polymerase chain reaction (PCR) has been applied for other food-borne pathogens such as Escherichia coli, Staphylococcus aureus and Streptococcus spp. A multiplex real-time PCR was developed for the simultaneous detection ...
Salmonella infections continue to cause gastrointestinal and systemic disease throughout the world. Salmonella typhimurium DT104 further poses a major health concern due to its acquisition of resistance to multiple antibiotics. The rapid detection of multiresistant S. typhimurium DT104 would facilitate strategies aimed at controlling this pathogen. We developed a specific and sensitive polymera...
