Abstract :
An epidemiological study was carried out through sero-surveillance to assess the tick disease outbreak in
Thondamuthur block of Coimbatore district in Tamil Nadu, India. Blood samples were collected from cattle with
severe tick infestation and other clinical symptoms for the screening of haemoparasites. Information regarding cattle
breed, age, sex, tick species and meteorological data were gathered. The results revealed that the theileriosis incidence
was higher (12.87%) compared to anaplasmosis (2.26%) and babesiosis (1.58%). Rhipicephalus microplus was observed
to be dominant (51.69%) compared to Hyalomma anatolicum (48.31%), Haemaphysalis sp. (8.58%) and Amblyomma sp.
(5.42%). Crossbred cattle were found to be more susceptible (96.39%) to tick infestation compared to native breeds
(3.61%). Higher tick infestation was recorded in the monsoon season (38.60%) and higher tick diseases were observed
in the summer season (23.19%). The results can provide an insight into the dynamics of tick disease outbreak in cattle
as influenced by the changes in various biotic and abiotic factors.
