A case of bovine cerebral theileriosis was confirmed at autopsy on a farm where 4 animals out of 70 died. All were less than 2 years old and all showed nervous signs. Serologically, no evidence was found of Theileria mutans or the Theileria parva group in young animals born on the farm. Six out of 13 calves 6-9 months of age were, however, serologically positive for Theileria? taurotragi and it...

AIM Tropical theileriosis is fatal hemoprotozoal disease of dairy animals caused by Theileria annulata. The aim of the present study was to detect the T. annulata and comparison of results of molecular and microscopic techniques. MATERIALS AND METHODS A total of 52 blood samples were collected from the cattle suspected for theileriosis across the Banaskantha district. All the samples were scr...

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 pa...

In the present study, we aimed to provide information on the serum content of sialic acids (TSA, LBSA, and PBSA), total antioxidant capacity (TAC), and adenosine deaminase (ADA) activity in cattle affected with naturally acquired theileriosis and anaplasmosis. A total of 55 Holstein cattle, comprising of 15 clinically healthy control animals, 20 cattle with theileriosis, and 20 with anaplasmosi...

AIM In India, dairy industries are important for the livelihood of small scale farmers and dairy owners. Tropical theileriosis, mostly affecting dairy cattle and buffaloes is a major threat to dairy and related industries. Tropical theileriosis is caused by Theileria annulata, a hemoprotozoan parasite transmitted by Ixodid ticks of Hyalomma spp. In the present study, we examined the clinical si...

The Erythrocyte Osmotic Fragility (EOF) in case of anaemic cattle mostly affected with haemolytic anaemia were evaluated in this study. As haemolytic anaemia is a consistent finding in different blood protozoan diseases like theileriosis and trypanosomiasis, determination of EOF in these cases shows the level of osmotic stress in the affected animals. The present study was also aimed to determi...

A combined formulation of parvaquone and frusemide (Fruvexon, Bimeda, Ireland) was evaluated for treatment experimental tropical theileriosis infection of calves. A total of Friesian dairy calves were infected with T. annulata sporozoite stabilate. Following infection with an equivalent of five infected Hyalomma excavatum ticks per calf all animals, developed severe clinical theileriosis. Fruve...

Received: Revised: Accepted: August 22, 2013 September 29, 2013 October 25, 2013 The aim of the study was to investigate and describe the clinical, parasitological haematological and biochemical findings induced by natural theileriosis in Camelus dromedarius. Sixty-seven out of 173 dromedary camels suffering clinically from fever, anorexia, swelling of the superficial lymph nodes, a rapid loss ...
