Journal of entomology and zoology studies, 2019
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...
Diagnostico-therapeutic management of theileriosis affected cross-bred cattle
Journal of entomology and zoology studies, 2019
A case of HF cross-bred cattle of seven years old with history of ticks, fever, reduced feed and water intake, bilateral nasal discharge, lacrimation, six months pregnant was presented to VCC Navania. On clinical examination revealed high body temperature, increased respiration, tachycardia with enlarged lymph nodes. It was suspected for Theileriosis and different laboratory diagnoses were performed. Smear was made from peripheral blood sample. On Giemsa staining Koch blue bodies were identified in the lymphocytes. Haematological parameters were done using peripheral blood samples. RBC`s, WBC`s, haemoglobin and packed cell volume found decreased as compared to normal values. The present case report showed that Theileria infection in cattle might be associated with haematological changes and successfully treated with single dose of Inj. Buparvoquone (2.5 mg/kg i.m.) and Inj. Oxytetracycline for next three days along with supportive therapy.
Bovine Theileriosis and its Control : A Review
2016
Arthropod transmitted hemoparasitic diseases are economically important vector-borne diseases of tropical and subtropical parts of the world including Ethiopia. Bovine theileriosis is a tick-borne hemoprotozoan disease of cattle caused by several theileria species and among them T. parva, the cause of East Coast fever and T. annulata, the causative agent of tropical theileriosis are the most pathogenic and economically important. The aim of this manuscript is to review currently available articles on the bovine theileriosis with a special attention to its control. Theileria have complex life cycles involving both vertebrate and invertebrate hosts. Tropical theileriosis and East Coast Fever are disease transmitted by Ixodid tick of the genus Hyalomma and Rhipicephalus, respectively. Furthermore, the sporozoites are transmitted to animals in the saliva of the feeding tick. Bovine theileriosis is characterized by high fever, weakness, weight loss, inappropriate appetite, conjunctival p...
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%).
Molecular diagnosis and treatment of oriental theileriosis in calves
The Pharma Innovation, 2020
Bovine theileriosis caused by Theileria orientalis is a tick borne haemoprotozoan disease and causes high morbidity and mortality in young calves. This paper deals with molecular diagnosis and treatment of oriental theileriosis in calves. The disease occurrence was found to be higher in calves aged between 3 to 8 months. The infected calves had low to moderate level of parasitaemia, except one calf which had high level of parasitaemia. Majority of infected calves were having mild anaemia with packed cell volume ranging between 15-23%. Molecular diagnosis using species specific primers confirmed the presence of T. orientalis in infected calves. Treatment with buparvaquone along with haematinics was found to be effective in calves.

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.
