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
Evaluation of the erythrocytes and leucocyte alterations in cows infected with Theileria annulata
Acta veterinaria, 2011
The percentages of anemia, parasitemia and leucocyte changes were investigated in bovine theileriosis in the Northwest of Iran. The hematological values in 91 cows with theileriosis were compared with 19 healthy ones. The disease was confirmed by the presence of parasites in the peripheral blood smear test. Five mLs of blood from the jugular vein was collected and mixed with EDTA. Hematological parameters and parasitemia were assessed by current laboratory methods. The mean for hematocrit (PCV), hemoglobin (Hb), total leucocytes counts (WBC) and erythrocyte count (RBCs) were 22.1%, 6.8 mg/dL, 7075/mL and 4x10 6 /mL, respectively. Mean total protein,
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.

The present study was carried out to determine the prevalence of Theileria annulata in large ruminants from two districts, Peshawar and Kohat, in Khyber Pukhtoon Khwa (Pakistan). Blood samples were collected from 95 cattle. Data on the characteristics of animals and herds were collected through questionnaires. No significant risk factors were found associated with the spread of tropical theileriosis in the study area. Two different parasite detection techniques, PCR amplification and screening of Giemsa stained slides, were compared and it was found that PCR amplification is a more sensitive tool (33.7 % parasite detection), as compared to smear scanning (5.2 % parasite detection) for the detection of Theileria annulata. 32 out of 95 animals, from both districts, produced the 721-bp fragment specific for Theileria annulata. Résumé : COMPARAISON DE DEUX TECHNIQUES DE DÉTECTION DE THEILERIA ANNULATA CHEZ DES BOVINS DE DEUX DISTRICTS DE LA PROVINCE DE KHYBER PUKHTOON KHWA (PAKISTAN) Une étude a été menée afin de déterminer la prévalence de Theileria annulata chez 95 bovidés de deux districts (Peshawar et Kohat) de la province de Khyber Pukhtoon Khwa au Pakistan. L'âge des bovins, la présence de tiques chez ceux-ci, ainsi que la présence de tiques chez les chiens du troupeau ne sont pas des facteurs de risque impliqués dans la diffusion de la theilériose dans la zone étudiée. La comparaison de deux techniques de détection du parasite (PCR et frottis sanguin coloré au Giemsa) a montré que la PCR était plus sensible (33,7 %) que le frottis (5,2 %).
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.

reducing production and death. The disease in endemic areas would be mild or subclinical in indigenous cattle and clinically acute in exotics. OBJECTIVES: This study was conducted to evaluate the resistance of indigenous cattle in comparison with Holstein and crossbred cattle against Theileria annulata through assessment of clinical signs and response to treatment. METHODS: For this purpose, the data history and clinical examination were observed on 51 naturally affected cattle with T. annulata (17 Holstein, 17 crossbred and 17 indigenous cows). Examination of blood smears was used for diagnosis. Detection of schizonts in lymph node punctured smears confirmed validity of the suspect samples. All three groups of cows were treated with buparvaquone along with oxytetracycline. Their clinical signs and the results of blood smear examinations were recorded before and 48 hours after treatment. The severity of clinical signs, parasitemia rates and response to treatment were compared among ...
Therapeutic management of theileriosis in bovines
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...
