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...

The objective of this study was to determine if there is an impact of heat stress of broiler chickens on number and survival of two types of Salmonella shed in the chicken's feces after an oral challenge. The data from this study indicate that heat stress did not result in higher levels or longer survival of Salmonella spp. shed in feces. It is possible that the duration or intensity of the hea...

During their colonization of plants, human enteric pathogens, such as Salmonella enterica, are known to benefit from interactions with phytopathogens. At least in part, benefits derived by Salmonella from the association with a soft rot caused by Pectobacterium carotovorum were shown to be dependent on Salmonella KdgR, a regulator of genes involved in the uptake and utilization of carbon source...

This study was conducted to analyze the prevalence and quantitative loads of Salmonella spp. on pig farms in Chiang Mai, Lamphun, Thailand to assess loading levels before slaughtering. The serotype diversity, antimicrobial-resistance pattern and pulse-field type of Salmonella spp. were also characterized to assess the dynamic propagation of the pathogen. The Salmonella-positive prevalence was 2...

Trianthema decandra L. root and root callus extracts of different solvents viz., petroleum ether, chloroform, ethyl acetate and ethanol were tested against both Gram positive and Gram negative bacteria and also against Fusarium spp. Root callus extract of chloroform and ethanol showed significant activity against Bacillus subtilis, B. cereus. Staphylococcus aureus, Staph. epidermis and also aga...

This study was performed to investigate the prevalence of Salmonella spp. in 100 free freshwater common carp samples using the classic culture technique. For the confirmation of the isolates at molecular levels, the invA gene was detected. Serotyping of the isolates was also detected. The presence of invA, class 1 (Cls1) integrons, and integrase (Int1) genes was demonstrated by PCR assay; and th...

We reviewed timeline information for a sample of Salmonella spp., Shigella spp., Campylobacter spp., and Escherichia coli O157:H7 cases and all confirmed foodborne outbreaks reported in 6 states during 2002. Increasing the timeliness of case follow-up, molecular subtyping, and linkage of results are critical to reducing delays in the investigation of foodborne outbreaks.

It has been shown that induced molting by complete feed withdrawal increases Salmonella horizontal transfer in laying hens and contamination in eggs. Zinc-containing diets have been used as an alternative means to induce molt in laying as a management while avoiding feed withdrawal. It is not known if the zinc in these molt diets would inhibit Salmonella spp. growth and therefore potentially mi...

BACKGROUND Human infections caused by pathogens transmitted from fish are quite common. The aim of this study was to isolate enteric pathogenic bacteria from fish that might be transmitted to humans after the handling or consumption of such fish. METHODOLOGY One hundred and twenty Nile tilapia fish harvested using various fishing methods were collected from fishermen in five fish landing beac...

Salmonella spp. are enteropathogenic gram-negative bacteria that use a large array of virulence factors to colonize the host, manipulate host cells, and resist the host's defense mechanisms. Even closely related Salmonella strains have different repertoires of virulence factors. Bacteriophages contribute substantially to this diversity. There is increasing evidence that the reassortment of viru...
