In-herd prevalence of Salmonella in 25 selected Minnesota swine farms
نویسنده
چکیده
Materials and methods: 25 Minnesota swine herds were selected for the study. None of the participating farms identified clinical Salmonella as a problem in their operations. Ileocecal lymph nodes of swine from the 25 farms were collected repeatedly at slaughter by bluntly dissecting lymph nodes from the caudal mesentery. These nodes were macerated and cultured for Salmonella. inapparent infections in pigs, are prevalent in swine herds, and are of concern to the food industry. The pattern of Salmonella serovars on a farm tends to be specific but variable. Prevalence of Salmonella varies greatly not only among farms, but also within farms, from one production site to another, and from shipment to shipment.

Quantitative Microbiological Evaluation of Salmonella Typhimurium Shed in Diarrhea, Loose, and Normal Stools of Infected Pigs
Control of within-herd transmission of Salmonella is important for reducing the prevalence of this organism on pig farms and for preventing Salmonella-contamination of pork. At the farm level, understanding the within-herd transmission of Salmonella can lead to more effective control. Salmonella infection is dependent on the inoculation dose; hence, quantitative evaluation of Salmonella shed in...

BACKGROUND African swine fever (ASF) is one of the major setbacks to development of the pig industry in Nigeria. It is enzootic in southwest Nigeria. We determined the sero-prevalence and factors associated with ASF among-herd seropositivity in 144 pig farms in six States from southwest Nigeria during the dry and rainy seasons using indirect Enzyme Linked Immunosorbent Assay (ELISA) for ASF IgG...
