Abstract

Cattle (Bos taurus) are intermediate hosts for three named species of Sarcocystis, S. cruzi, S. hirsuta, and S. hominis. Recently, a fourth species was identified and named S. sinensis. However, S. sinensis originally named a species of Sarcocystis in water buffalo (Bubalus bubalis) in China. Based ...

Neospora caninum is protozoan parasite with domestic and wild dogs, coyotes and grey wolves as the definitive hosts and many warm-blooded animals as intermediate hosts. It was cultivated and named in 1988. Neosporosis is a major disease of cattle and has no public health significance. Since 1990's ...

Abstract

Cattle (Bos taurus) are intermediate hosts for four species of Sarcocystis, namely Sarcocystis cruzi, Sarcocystis hirsuta, Sarcocystis hominis, and Sarcocystis rommeli. Of these four species, mature sarcocysts of S. cruzi are thin-walled (<1 µm), whereas S. hirsuta, S. hominis, and S. rommeli have thick walls (4...

Abstract

Neospora caninum is a protozoan parasite of animals. Until 1988, it was misdiagnosed as Toxoplasma gondii. Since its first recognition in 1984 in dogs and the description of a new genus and species Neospora caninum in 1988, neosporosis has emerged as a serious disease of cattle and dogs worldwide....

Abstract

Little is known of the epidemiology of toxoplasmosis in Minnesota. Here, we evaluated Toxoplasma gondii infection in 50 wild bobcats (Lynx rufus) and 75 other animals on/near 10 cattle farms. Antibodies to T. gondii were assayed in serum samples or tissue fluids by the modified agglutination test...
