School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research
Within the last decade a new etiologic agent has been identified as a possible cause of diarrhea in humans and domestic animals—that being the protozoan parasite Cryptosporidium. The purpose of this study was to determine the incidence and distribution of Cryptosporidium in the state of Nebraska, to determine if Cryptosporidium occurs more frequently in association with other enteropathogens and to determine about the relation of scouring in the calves to infection with Cryptosporidium. A total of 620 fecal samples from 334 dairy calves from 71 herds in Nebraska were examined for cyptosporidial oocysts using the Sheather’s sugar flotation …
Atrophic Rhinitis In Pigs, A R. Mercy
Atrophic Rhinitis In Pigs, A R. Mercy
Journal of the Department of Agriculture, Western Australia, Series 4
Severe atrophic rhinitis in pigs recurred recently in Australia after an apparent absence of some 20 years. The first of these recent cases occurred in a Westerm Australian herd in late 1984 and since then six other local herds have reported the disease. Severe atrophic rhinitis has also been seen recently in South Australia.
Atrophic rhinitis is a complex disease which causes degeneration of the nasal cavity, twisting of the snout and sometimes occasional bleeding from the nose.
It occurs only in pigs and severely affected animals may have a slower growth rate.
