Bovine haemoparasites are cosmopolitan in distribution and are known to cause substantial losses to the cattle industry. In spite of their economic importance there remains a dearth of information on their molecular epidemiology in many parts of the world including Malaysia. To ascertain the molecular prevalence and species co-infection of bovine haemoparasites in the country blood samples were collected from 1 045 heads of beef and dairy cattle on 43 farms from six geographical zones throughout Peninsular Malaysia. Samples subjected to PCR amplification of parasite species-specific genetic fragments revealed that Anaplasma marginale was the most prevalent haemoparasite (72.6) followed by Theileria orientalis(49.8) Candidatus Mycoplasma haemobos ( 47. 0 ) Babesia bovis(32. 5) Babesia bigemina (30.5) and Trypanosomaevansi(17.9). A high percentage (92.1) of cattle was infected with either one or more haemoparasites. Triple haemoparasite species co-infection was the most prevalent (25.6) followed closely by double species co-infection (25.1). The most common (8.8) and significantly correlated(rs 0.250; p0.01) combination was A. marginale T.orientalis. The present study constitutes the first attempt in the country to document the molecular prevalence and species co-infection of bovine haemoparasites over a wide spatial distribution. The data obtained will facilitate treatment control and prevention measures to improve the local cattle industry.

Abstract

Bovine haemoparasites are cosmopolitan in distribution and are known to cause substantial losses to the cattle industry. In spite of their economic importance there remains a dearth of information on their molecular epidemiology in many parts of the world including Malaysia. To ascertain the molecular prevalence and species co-infection of bovine haemoparasites in the country blood samples were collected from 1 045 heads of beef and dairy cattle on 43 farms from six geographical zones throughout Peninsular Malaysia. Samples subjected to PCR amplification of parasite species-specific genetic fragments revealed that Anaplasma marginale was the most prevalent haemoparasite (72.6) followed by Theileria orientalis(49.8) Candidatus Mycoplasma haemobos ( 47. 0 ) Babesia bovis(32. 5) Babesia bigemina (30.5) and Trypanosomaevansi(17.9). A high percentage (92.1) of cattle was infected with either one or more haemoparasites. Triple haemoparasite species co-infection was the most prevalent (25.6) followed closely by double species co-infection (25.1). The most common (8.8) and significantly correlated(rs 0.250; p0.01) combination was A. marginale T.orientalis. The present study constitutes the first attempt in the country to document the molecular prevalence and species co-infection of bovine haemoparasites over a wide spatial distribution. The data obtained will facilitate treatment control and prevention measures to improve the local cattle industry.
