Abstract
Theileriosis is an important haemoparasitic disease of goats which causes serious economic losses to
farmers. There is a paucity of information on the clinico-haemato-biochemical aspects of caprine
theileriosis in Kerala. The present study was undertaken to evaluate the haemato-biochemical alterations
associated with clinical cases of caprine theileriosis in twenty five smear positive goats in Thrissur
district, Kerala. Major clinical signs observed were anaemia, fever, lymphnode enlargement, anorexia,
respiratory distress. Haemato-biochemical analysis revealed macrocytic hypochromic anaemia with low
Hb, Volume of Packed Red Cells (VPRC), platelet, Total Erythrocyte Count (TEC) and
hyperproteinaemia with hyperglobulinaemia in the affected goats.
Keywords: Theileriosis, macrocytic hypochromic anaemia, hyperproteinemaia, hyperglobulinaemia
1. Introduction
Theileriosis is an economically important tick-borne disease affecting wild and domestic
ruminants in the tropics and subtropics. They are transmitted by ixodid ticks of the genus
Haemaphysalis, Hyalomma and Rhipicephalus. Small ruminants play a pivotal role in
sustaining the economic status of an agriculture nation like India. Tick and tick-borne diseases
are now considered as the major threat to the animal production sector. Among the tick-borne
diseases in goats theileriosis is the major aetiology of anaemia and decrease in productivity
while considering the Kerala scenario. Extensive studies and information regarding bovine
theileriosis are already available from all over the country including Kerala. Even though there
exists a paucity of information on detailed clinical and haemato-biochemical alterations
associated with the theileriosis in goats. Among the Theileria spp. that affect small ruminants
such as sheep and goats, T. uilenbergi, T. lestoquardi, and T.
luwenshuni are considered as highly pathogenic (Uilenberg, 1981 and Yin et al., 2007)
[16, 18]
.
Nonpathogenic or mildly pathogenic species are T. separata, T. ovis, and T. recondita (Alani
and Herbert, 1988)
[1]
. The acute cases of theileriosis are manifested by fever, lymphnode
enlargement, anaemia and high mortality rate.
Prevalence of Theileria spp. in goats were reported from different regions of India including
Kerala till recently, but detailed studies on clinico-therapeutic and haemato-biochemical
changes associated with the disease was not yet revealed. Hence in the light of increase in
number of caprine theileriosis being reported from Thrissur district, the present study was
undertaken to findout the haemato-biochemical alterations associated with theileriosis in goats.
2. Materials and methods
The study was conducted at the Department of Veterinary Epidemiology and Preventive
Medicine, College of Veterinary and Animal Sciences, Mannuthy during the period from June
2019 to December 2020. Occurrence of caprine theileriosis and haemato-biochemical changes
associated with theileriosis was studied among goats presented to Kerala Veterinary and
Animal Sciences University Hospitals at Mannuthy and Kokkalai, Veterinary hospitals under
Animal Husbandry Department and also those belonging to organized farms and house-holds
in and around Thrissur district. One hundred goats which had shown predominant clinical
signs suggestive of theileriosis like anaemia, fever, lymphadenopathy, cough and nasal
discharge were screened for theileriosis. Detailed clinical examination of the animals was
done. Anamnesis and signalment were recorded for all the animals. Peripheral blood smear
examination was done to identify the goats positive for theileriosis. Thin blood smears were
prepared on glass slides using a drop of blood collected from ear vein and air dried. The blood
smears were stained with Field’s staining method.
