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...

tropical theileriosis is a tick-transmitted disease which caused by obligative intracellular protozoan theileria annulata. diagnosis is usually based on identification of parasite in giemsa stained smears of peripheral blood, spleen or lymph nodes. today, the molecular methods with high sensitivity and specificity are used for diagnosis of infected and carrier animals, epidemiological and phylo...

Live attenuated vaccines are used to combat tropical theileriosis in North Africa, the Middle East, India, and China. The attenuation process is empirical and occurs only after many months, sometimes years, of in vitro culture of virulent clinical isolates. During this extensive culturing, attenuated lines lose their vaccine potential. To circumvent this we engineered the rapid ablation of the ...

Theileria parasites invade and transform bovine leukocytes causing either East Coast fever (T. parva), or tropical theileriosis (T. annulata). Susceptible animals usually die within weeks of infection, but indigenous infected cattle show markedly reduced pathology, suggesting that host genetic factors may cause disease susceptibility. Attenuated live vaccines are widely used to control tropical...

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...

Bovine theileriosis is a tick-borne disease caused by obligate intracellular parasites related to the genus Theileria. Cellular immune responses protect cattle against pathogens through the activation of immune cells. Nowadays, live, attenuated vaccine of Theileria annulata (T. annulata) is being produced in Iran and is recommended for active cattle immunization. Detection of the immunogenic  a...

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 ...

The diagnosis of ruminant theileriosis in Turkey is based on microscopical examination of thin blood and lymph smears, serology, traditional staining methods of the salivary glands of ticks and molecular techniques. Although some investigators reported that T. mutans was found in cattle with microscopic examination (7.4%-36.7%) and experimental study, they did not detect this parasite using mol...

Little is known about tick-borne diseases in Saudi Arabia, particularly regarding the prevalence of theileriosis in small ruminants. This survey studied the potential vectors of malignant theileriosis in Saudi Arabian sheep. Blood, lymph node and tick samples were collected from animals being treated or necropsied at the Veterinary Diagnostic Laboratory in Jeddah, Makkah (western region), and B...
