Intracellular bacterial pathogens like Salmonella enterica use secretion systems, such as the Type III Secretion System, to deliver virulence factors into host cells in order to invade and colonize these cells. Salmonella virulence factors include a suite of effector proteins that remodel the host cell to facilitate bacterial internalization, replication, and evasion of host immune surveillance...

BACKGROUND Feeding raw meat-based diets (RMBD) to companion animals raises public health concerns for both animals and humans. While considerable attention has been paid to bacterial contamination of commercial pet food, few literature studies have investigated foodborne disease in companion animals. Salmonellosis is reported to be infrequent in cats but no known data or studies estimating feli...

Globally, there has been an increase in squamates (particularly lizards and snakes) being kept as pets. Additionally, urban spread has resulted in greater human encroachment and interaction with the natural habitat of wild squamates. A potential consequence of increasing human interaction with squamates is the increased potential for disease transfer. This review collates the literature describ...

Salmonella enterica serovar Weltevreden is not a commonly isolated serotype in India. We report isolation of Salmonella Weltevreden, from an unusual site--an ulcer on the gluteal region of a patient who had undergone coronary artery bypass surgery. To our knowledge, Salmonellae have never been reported to cause isolated ulcerative lesions on the skin. This is the first report of an isolated ulc...

Salmonella enterica subspecies 1 serovar Typhimurium is a common cause of gastrointestinal infections. The host's innate immune system and a complex set of Salmonella virulence factors are thought to contribute to enteric disease. The serovar Typhimurium virulence factors have been studied extensively by using tissue culture assays, and bovine infection models have been used to verify the role ...

THE ANTIBACTERIAL ECTIVITY OF COPPER NANOPARTICLES AND COMBINATION WITH COTRIMOXAZOLE AGAINST SALMONELLA TYPHI IN VITRO ANIMAL MODEL

Genetic resistance to Salmonella infection in experimental animal models is well described. However, genetic resistance in domestic animals, which has potentially great value in terms of controlling Salmonella in the food chain, has been relatively poorly described. Recent advances in genetics and immunology have identified several factors that influence resistance in chickens and pigs in parti...

Salmonellosis remains an important cause of human disease worldwide. While there are several licensed vaccines for Salmonella enterica serovar Typhi, these vaccines are generally ineffective against other Salmonella serovars. Vaccines that target paratyphoid and nontyphoidal Salmonella serovars are very much in need. Preclinical evaluation of candidate vaccines is highly dependent on the availa...

Poultry meat is an important food product and the broiler chicken-related industry is an economically important component of the agro-industry in the European Union (EU). The industry however is under pressure and faces many challenges. Most importantly, there is a demand for meat of high nutritional value and free of microbiological and chemical hazards. Unfortunately poultry meat is one of th...

Animal feed is at the beginning of the food safety chain in the "farm-to-fork" model. The emergence of variant Creutzfeldt-Jakob disease has raised awareness of the importance of contaminated animal feed, but less attention has been paid to the role of bacterial contamination of animal feed in human foodborne illness. In the United States, animal feed is frequently contaminated with non-Typhi s...
