“…Theilerial parasites infect a broad range of wild and domestic artiodactyls throughout the world with highest prevalence in tropical and subtropical climates of Africa, Europe, Australia, and Asia. 4,13 East Coast fever, caused by T. parva, is the most severe theilerial disease of domestic cattle. The life cycle of Theileria spp.…”

Theileriosis in a Missouri Beef Herd Caused by Theileria buffeli

Abstract.A 6-year-old Simmental cow infected with Theileria buffeli had a clinical disease characterized by theilerial parasitemia, macrocytic normochromic anemia with acanthocytosis and spherocytosis, lymphoid hyperplasia (lymphocytosis, edematous lymphadenomegaly), dysproteinemia, evidence of liver disease, and a low serum antibody titer against T. buffeli. The cow was in a herd in which all cattle originated in Missouri; 22/75 (29%) of cattle had a theilerial parasitemia and 26/75 (35%) had titers to T. buffeli of Ն1 : 160. Classification of the Missouri bovine organism as T. buffeli was based on DNA sequencing and comparison to sequences for T. buffeli and Theileria sp. type A obtained from GenBank. Intraerythrocytic veils and piroplasms were seen during transmission electron microscopy. The organism was successfully transmitted to two splenectomized calves, which developed mild anemias while parasitemic. Blood from the second calf was used as the source of T. buffeli antigen for an indirect immunofluorescence antibody test. Theilerial isolates from a Missouri white-tailed deer were also sequenced and resembled Theileria sp. types F and G and were not consistent with the bovine organism.

Throughout four successive seasons (winter, spring, summer and autumn), one hundred and ninety five camels (Camelus dromedarius) from slaughtered houses in different regions at Assiut governorate were examined for protozoa parasites in blood and muscles. These parasites were Trypanosoma evansi, Trypanosoma type 1. (n.sp.) Babesia sp, Theileria cameli in blood and Sarcosystis sp. in muscles.The prevalence of infection for the different parasites in both blood and muscles was also studied through the different seasons.Generally Sarcosystis sp. was represented the highest incidence of infection (55.38%) in the present study especially in spring (81.08%). The lowest incidence of infection was represented in Trypanosoma evansi (2.5%). At the same time the lowest incidence through different seasons was represented in Theileria cameli and Trypanosoma evansi (4.83%) in autumn.

“…As already stated in this paper the disease in the Southern and Central provinces was originally diagnosed as CD, but one wonders the validity of this term. All the Zambian isolates were put in group B of T. parva together with Theileria stocks from other countries which did not react with MAbs 2, 3, 15 and 20 [11,12]. In the advent of this change in character there may be need of testing the MAb profiles of T. parva parasites in the other countries especially in those countries where foreign stocks were used in the immunization programs.…”

ABSTRACT. Theileria parva parasites have been isolated from different locations in Zambia where malignant theileriosis has been recorded. A total of 16 bovine lymphocytic cell lines infected with T. parva schizonts were characterized using a panel of anti-schizont monoclonal antibodies (MAbs). Comparison of the Theileria stocks isolated before (old) and after (new) the Muguga cocktail of T. parva from Kenya was used to vaccinate cattle against theileriosis in Zambia revealed differences in their reactivity against MAbs. The new isolates are showing MAb profiles similar to that exhibited by the Muguga cocktail which was used to vaccinate cattle in these areas between 1983 and 1989. These results suggest that the use of the Muguga cocktail to vaccinate animals against theileriosis in Zambia may have introduced Theileria stocks of different antigenic properties. -KEY WORDS: immunization, monoclonal antibody, Muguga cocktail, Theileria parva.
