Abstract
Bovine anaplasmosis refers to an intraerythrocytic disease in cattle.
The causative agent of this disease is the bacteria, Anaplasma marginale. A
seroprevalence study on bovine anaplasmosis was conducted to determine the
disease status in Malaysia. Sera from all states, except Kuala Lumpur, were collected
and tested for the presence of Anaplasma marginale antibodies by c-ELISA. Of the
455 samples collected nationwide, 77.6% were tested positive for bovine
anaplasmosis. Pahang is the state with the highest infection rate at 100%, followed
by Terengganu and Selangor at 95% each. The states with the lowest infection rates
are Sabah and Sarawak at 59.2% and 61.5% respectively. A subsequent study has
been conducted in Pahang in November 2013. Out of 26 samples, 18 samples
(69.2%) tested positive, which is a reduction in the disease prevalence rate. Visits to
Pahang farms were done and questionnaires were distributed to farmers and their
workers to help further understand the husbandry and its significance to the disease.
A survey in Pahang shows that there was an association between prevalence and
farm management. Based on the responses of respondents, it was discovered that
many of them received up to secondary education only, and only a handful of them
have heard of bovine anaplasmosis. However, no one understood the importance of
this disease and its implications to their source of income and the
Malaysian economy.
