introduction: in iran, invasive nontyphoidal salmonella (ints) disease causes severe bacteremic illness among children <5 years old. the global yearly incidence of ints disease in children was reported to be in the 3.4 (range  2.1-6.5) million cases,  (overall incidence 49 cases (range 30-94) per 100,000 population), the ints case-fatality ratio (cfr) of 20% yielded 681,316  deaths annually. me...

BACKGROUND Salmonella contaminated animal feed is a major source for introducing Salmonella into the animal derived food chain. Because soybeans frequently are contaminated with Salmonella, soybean meal used as animal feed material, a by-product of a "crushing plant" which produces oil from soybeans, can be important source of Salmonella in the animal feed. RESULTS During the 19-year period, ...

BACKGROUND Food borne infections caused by Salmonella enterica species are increasing globally and pregnancy poses a significant threat in developing countries, where sanitation facilities are inadequate. Thus, the present study was designed to delineate the effect of Salmonella infection during pregnancy. METHOD Pregnant, BALB/c mice were challenged orally with Salmonella enterica serovar Ty...

The dissemination of Salmonella into various lymphoid-like organs in young broiler chicks after oral and intracloacal inoculation was studied. A three-strain cocktail of Salmonella Typhimurium, Salmonella Montevideo, and Salmonella Enteritidis was administered either orally or intracloacally to day-old chicks. After 1 h, 1 day, or 1 week, the ceca, thymus, liver and gallbladder, spleen, and bur...

Salmonella accounts for approximately 50% of produce-associated outbreaks in the United States, several of which have been traced back to contamination in the produce production environment. To quantify Salmonella diversity and aid in identification of Salmonella contamination sources, we characterized Salmonella isolates from two geographically diverse produce-growing regions in the United Sta...

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...

Salmonella is a facultative intracellular Gram-negative bacterium, responsible for a wide range of food- and water-borne diseases ranging from gastroenteritis to typhoid fever depending on hosts and serotypes. Salmonella thus represents a major threat to public health. A key step in Salmonella pathogenesis is the invasion of phagocytic and non-phagocytic host cells. To trigger its own internali...

Salmonella is an important pathogen for both humans and animals. Although the organism has been intensively studied during the last century, much remains to be learned about this pathogen. The complicated nomenclature system of Salmonella has long been a subject of discussion. In 2005, "Salmonella enterica" finally gained official approval as the type species of the genus Salmonella. The genus ...

Salmonella is the most important human pathogen associated with shell eggs. Salmonella Enteritidis is the serotype most often implicated in outbreaks, although other serotypes have been recovered from eggs and from the commercial shell egg washing environment. Many sample methods are used to recover microorganisms from eggshells and membranes. A shell rinse and modified shell-and-membrane crush...

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., and ...
