During 2000-2012, U.S. Air Force Public Health Offices reported 3,429 cases of gastrointestinal infection (GI) diagnosed at Air Force medical treatment facilities. The four most commonly reported specific etiologies of GIs accounted for 86.7% of all GI cases (n=2,972). Salmonellosis accounted for 41.4% (n=1,420) of all cases. The next most commonly reported events were associated with Campyloba...

Various features of salmonellosis were examined in a burned-mouse model. In this model, which uses an outbred mouse strain, a challenge dose of ca. 100 CFU with any of several strains of Salmonella typhimurium caused a fatal infection. A variety of mutated strains attenuated for virulence in Salmonella-susceptible parenterally infected mice were also attenuated in the burned-mouse model. When a...

Salmonella spp. colonise a wide range of hosts and all the major livestock species (poultry, cattle, and pigs) can become colonised, frequently asymptomatically, eventually producing contaminated meat and other food products. Food-borne outbreaks of salmonellosis are routinely observed and frequently reported. This is a reflection of a low infectious dose in humans, especially when delivered in...

The incidence of invasive salmonellosis has increased among children and HIV-infected adults in Malawi. This has been associated with the emergence of drug resistance in the non-typhoidal Salmonella serovars Enteritidis and Typhimurium. In contrast, S. Typhi isolates have remained fully sensitive to commonly used antibiotics and the estimated incidence of typhoid fever, although still present, ...

BACKGROUND Salmonella enterica Typhimurium (S. Typhimurium) is the most common cause of bovine salmonellosis in Japan and where it is also cause of salmonellosis in wild birds. In 2008, a postpartum cow at a dairy farm developed diarrhea caused by S. Typhimurium. The herd was extensively surveilled for Salmonella sp. and we characterized bacterial isolates from this and other cows to determine ...

Abstract Introduction Salmonellosis is an important public health problem throughout the world. Salmonella meningitis is an unusual manifestation of salmonellosis and remains a threat to children below 2 years of age. Young children especially infants and immunocompromised adults are particularly at higher risk of acquiring this bacteria. The disease has a poor prognosis and is associated with ...

Sporadic salmonellosis has been reported in mature lactating dairy cattle in the southwestern United States and is an intriguing problem in that Salmonella can be cultured from faecal samples of these cattle throughout the year. However, it is pathogenic only during late summer/early autumn and in certain years. We sampled apparently healthy (n=10) and diarrhoeic (n=10) cattle during an outbrea...

the clinical features of salmonellosis and prevalence of salmonella serogroups in calves were studied on one hundred and thirty two suspected calves in dairy farms around tehran. clinical examinations were carried out and the faecal or tissue (if calve was euthanized or dead) samples were collected for bacterial culture. the results were analyzed with chi-square statistical test. salmonella spp...

Salmonellosis occurs worldwide in dogs and cats and is of clinical and public-health importance. Infections in these animals are usually asymptomatic, with intermittent excretion of Salmonella in faeces. Clinical syndromes, which are comparatively uncommon, are often most severe in young or debilitated animals. These syndromes include enterocolitis, septicaemia and, rarely, abortions. Conjuncti...

BACKGROUND Salmonella spp. have been isolated from a wide range of wild animals. Opportunistic wild carnivores such as red foxes (Vulpes vulpes) and badgers (Meles meles) may act as environmental indicators or as potential sources of salmonellosis in humans. The present study characterizes Salmonella spp. isolated from the intestinal contents of hunted or dead red foxes (n = 509) and badgers (n...
