Experimental inoculation of Treponema pedis T A4 failed to induce ear necrosis in pigs
Ear necrosis is a syndrome affecting pigs shortly after weaning and is regarded as an animal welfare issue. The etiology is unknown but Treponema spp., predominantly Treponema pedis, are commonly detected in the lesions. Oral treponemes have been suggested as source of infection, transferred by biting and licking behavior. In this study, five pigs were intradermally inoculated with Treponema pe...
متن کاملEar necrosis syndrome in weaning pigs associated with PCV2 infection: A case report
Porcine necrotic ear syndrome (PNES) in pigs has been reported as an increasing health problem in many countries with intensive pig farming. The etiology of this disease is complex and the presumed triggering factors can be divided into infectious and non-infectious agents. The present report describes a case of Porcine Circovirus type 2 (PCV2), infection associated with lesions of PNES at the ...
متن کاملTreponema spp. in Porcine Skin Ulcers
The hypothesis tested in this work is that bacteria of genus Treponema play a main role when shoulder ulcers and ear necrosis occur in an infectious or severe form, and perhaps also in other skin conditions in the pig. Samples were collected from pigs in 19 Swedish herds 2010-2011. The sampled skin lesions included 52 shoulder ulcers, 57 ear necroses, 4 facial necroses and 5 other skin ulcers. ...
متن کاملGenome-Wide Relatedness of Treponema pedis, from Gingiva and Necrotic Skin Lesions of Pigs, with the Human Oral Pathogen Treponema denticola
Treponema pedis and T. denticola are two genetically related species with different origins of isolation. Treponema denticola is part of the human oral microbiota and is associated with periodontitis while T. pedis has been isolated from skin lesions in animals, e.g., digital dermatitis in cattle and necrotic ulcers in pigs. Although multiple Treponema phylotypes may exist in ulcerative lesions...
متن کاملExperimental infection with Treponema hyodysenteriae in guinea pigs.
Outbred and inbred (Hartley strain) guinea pigs (GP) were inoculated intragastrically with pathogenic and nonpathogenic Treponema hyodysenteriae. GP 3 to 16 weeks old received T. hyodysenteriae after a fasting period of 36 to 72 h. Infected GP with pathogenic T. hyodysenteriae developed a diarrheal and/or depressive condition, with mucus but not blood in the feces. Of 88 GP, 40 had gross lesion...
