| detection of lawsonia intracellularis in swine using polymerase chain reaction methodology. | the polymerase chain reaction (pcr) was evaluated for its usefulness as a diagnostic tool to detect lawsonia (ileal symbiont) intracellularis. porcine ilea were collected from swine cases submitted to the iowa state university veterinary diagnostic laboratory between december 1, 1994, and june 30, 1995. sampling was random, with no regard to health status. there were 621 ileum scrapings evaluated using the pcr technique. thirty-five of the samples were positive, either by pcr or conventional dia ... | 1999 | 9925211 |
| prevalence of campylobacter spp. relative to other enteric pathogens in grow-finish pigs with diarrhea. | salmonella spp., lawsonia intracellularis, and brachyspira spp. are pathogens commonly associated with diarrhea in growing and finishing pigs. brachyspira spp. infection has recently reemerged as a significant concern due to an increase in the incidence of swine dysentery; however, the mechanisms underlying this increase in dysentery remain largely unknown. pigs are also well-recognized as potential carriers of campylobacter spp., particularly campylobacter coli, yet enteric disease in swine ass ... | 2013 | 23792232 |
