Theileriosis is a major tick haemoprotozoan disease in cattle, buffalo, sheep, goat and horses as well as wild ruminant animals However, indigenous cattle (Boss indicus) are less affected by Theileriosis than crossbred cattle. Among the various tick born haemoprotozoan disease, bovine tropical Theileriosis caused by Theileria annulata and transmitted by Hyalomma anatolicum anatolicum ticks species, results in lethal infections and considerable high mortality in crossbred cattle then the Zebu cattle. Once infected the animals remain carrier for life time, since the organisms hide in macrophage and lymphoid tissue. The compromises the immune system and the animal are prone to a number of super infections. 5 clinical cases of Theileriosis in calves recorded at Veterinary Clinical Complex, Post Graduate Institute of Veterinary Education & Research, Jaipur (Raj.) during October, 2018 to November, 2018. Clinically, fever, tachycardia, polypnea, reduced appetite, dullness or emaciated body...
Diagnosis and therapeutic management of bovine theileriosis
2019
Bovine Theileriosis is a haemoprotozoan disease caused by Theileria spp in cattle lead to huge depreciation in terms of economy of farmer and mainly transmitted by Hyalomma and Rhipicephalus ticks. In the present study a total of ten cases suspected for theileriosis with the clinical signs such as elevated body temperature, enlarged superficial lymphodes, anaemia, tachycardia and presence of ticks over the body were studied. Further they were subjected to haematological examination, thin blood smear examination and further confirmed by PCR assay. The results revealed that, haematological examinations implicated severe anaemia whereas thin blood smear examination showed presence of pleomorphic theilerial organisms in the RBC’s and amplification of expected PCR product of 1098-bp by targeting theileria genus specific primers for the SSU rRNA gene confirming theileriosis in cattle. The affected animals were treated with Inj Buparvaquone @ 3.5 mg/Kg given deep intramuscularly once as an...

Bovine theileriosis listed one of the tick-borne diseases of crucial concern worldwide.. The objectives of this study were to investigate the occurrence of tropical theileriosis in a farm of cattle demonstrating acute manifestations by Giemsa stained blood smears and Tams1gene based polymerase chain reaction (Tams-1 PCR). Moreover, to follow up the treatment with buparvaquone and long-acting oxytetracycline on the clinical, parasitological and hematological profile of infected cattle. Blood samples were collected from cattle (n=25) suspecting Theileria annulata (T. annulata) infection and healthy ones (n = 10; clinically and parasitologically free) in Sharkia Governorate Egypt, during July-August 2019. Fever (40-41°C), superficial lymph nodes enlargement, corneal opacity, and cases of non-specific abortion were the most manifestations recognized. The microscopic examination of blood smears (n=25) showed intracellular signet ring piroplasms which, confirmed using Tams1gene based PCR that identified Theileria parasites as T. annulata. Haemogram revealed normocytic normochromic anemia, meanwhile, the total leukocyte count (TLC) and lymphocytes significantly increased (P ≤0. 05) compared to the control ones using T-test. The cure rate in all treated cattle was (88%; 22 / 25) two weeks after the treatment. A rapid decrease in parasitemia in adults and young cattle to 0.5%, and 7%, respectively one week after treatment, and a significant increase in hematocrit percent and erythrocyte count, as well as macrocytic hypochromic anemia, was recorded two weeks from the beginning of the therapy. In conclusion, the response of Infection with T. annulata plays a vital role in occurrence of anemia and in changing blood parameters. Buparvaquone and oxytetracycline are indicated in the treatment of acute theileriosis together with iron supplements.
Control and therapeutic management of bovine tropical theileriosis in crossbred cattle
Journal of Parasitic Diseases, 2014
Bovine tropical theileriosis (BTT) is a disease of worldwide economic importance in cattle, caused by Theileria annulata, a protozoan parasite, and transmitted cyclically by ticks. The disease is one of the serious constraints to dairy industry in endemic areas like India, leading to fatal infections in exotic cattle and significant mortality in cross-bred cattle and zebu cattle. The present report demonstrates the clinical manifestation, haematological alteration and therapeutic management of theileriosis cases in a cross-bred cattle dairy farm at district Bijnor, Uttar Pradesh. Clinical examination of affected animals revealed high rectal temperature (104-106°F), generalized enlargement of superficial lymph nodes, pallor mucous, apathy and watery blood. The affected animals were severely infested with Hyalomma anatolicum ticks. The blood smears examination after staining with Leishman stain revealed the presence of typical Theileria organisms. Buparvaquone along with symptomatic and supportive therapy could cure all the animals.
Study of occurrence of theileriosis in cattle from Parbhani district, Maharashtra, India
The Pharma Innovation Journal, 2019
The present study was carried out to study occurrence of theileriosis in dairy cattle from Parbhani district of Maharashtra. The inclusion criteria involved examining suspected cattle for theileriosis based on the clinical signs like elevated body temperature, enlargement of superficial lymph nodes, conjunctival petechiae and presence of ticks on body of animal. Confirmation of theileriosis was done by peripheral blood smear examination and lymph node biopsy by Giemsa's staining method and blood smear was taken as gold standard to study occurrence. In total 67 suspected cattle were screened during which fifteen cattle were found positive for Theileria annulata infection. Overall occurrence of theileriosis was found 22.38%, however, age-wise occurrence was higher in below 6 month of age group (33.33%) followed by 6 month to 2 year age group (25.00%) and least in above 2 year age group. Sex wise occurrence revealed 40.00% in males and 20.96% in female. Whereas, breed wise occurrence was higher in Jersey breed (28.57%) as compared to Holstein Freisian cattle and no case of theileriosis found in indigenous cattle. Month wise occurrence revealed highest occurrence was in the month of May (33.33%) followed by April (26.66%), March (20.00%) and least occurrence was observed in the month of January, February and June (6.66%).
Theileriosis in Tharparkar Calves and its Therapeutic Management-Case Study
International Journal of Current Microbiology and Applied Sciences, 2018
Theileria diseases are known to cause heavy losses to the livestock industry. Lack of appropriate control strategies for this disease lead to increase in mortality, reduced milk production, lowered animal drought power, ultimately produces constraint to the dairy industry. Theileriosis is a tick-borne disease, caused by Theileria annulata. The vector ticks are of the genus Hyalomma. This case report revealed the successful therapeutic management of theileriosis in Tharparkar calves. Clinical examination of affected calves revealed high fever (104.50 F to 1060F), dullness, anorexia and enlarged lymph nodes. The blood smears examination after staining revealed the presence of Theileria organisms. Buparvaquone along with supportive therapy could cure calves.

T ropical theileriosis is one of the most prevalent serious problem with greatest economic and mortality impact of cattle in Iraq (Aktas et al., 2004). This disease is one of tick-borne protozoal disease caused by Theileria of the suborder Piroplasmorina which its transmitted by ticks from genus Hyalomma spp (Salih et al., 2007; Aziz and AL-Barwary, 2020). This protozoan is obligatory intracellular hemoparasites, and two species invaded to cattle T. parva (causes East Coast fever) and T. annulata (causes tropical theileriosis) (Sandhu et al., 1998; Singh et al., 2001). The infection occurs due to the presence and multiplication of parasite inside WBCs and then RBCs and resulting in progressive and severe macrocytic hemolytic anemia (Radostits et al., 2000). The main clinical signs are enlargement of prescapular lymph nodes, fever, diarrhea, pale of mucous membrane, decrease of milk production, abortion in preg
