Comparative study of Anaplasma parasites in tick carrying buffaloes and cattle

Abstract

Abstract:A comparative study on the prevalence of Anaplasma parasite was conducted on ticks carrying buffaloes and cattle. Five hundred blood samples of both animals (250 of each) were collected during February, March and April. Thin blood smears on glass slides were made, fixed in 100% methyl alcohol and examined. Microscopic examination revealed that 205 (41%) animals had Anaplasma parasites, out of which 89, 44 and 72 animals had Anaplasma marginale, Anaplasma centrale and mixed infection respectively. Infected buffaloes and cattle were 75 and 130 respectively. The infection in female was 53 and 92 in buffaloes and cattle respectively. Twenty-two and 92 blood samples of male were found positive in buffaloes and cattle respectively. Comparative study revealed that the cattle were 26.82% more susceptible than buffaloes. The parasite prevailing percentage in female of both animals was slightly higher than that of the male. This investigation was aimed at studying the comparative prevalence of Anaplasma parasite in tick carrying buffaloes and cattle.

Molecular epidemiological survey and genetic analysis of vector-borne infections of cattle in Luzon Island, the Philippines

“…This finding is supported by some reports that cattle were more susceptible than water buffalo to A. marginale infection (Rajput et al, 2005). 16S rRNA partial gene of A. marginale sequences were 100% identical with each of the samples and formed a similar lineage with several sequences in the GenBank from the USA, China, Japan, Israel, Australia, and the Philippines.…”

Bacteria of the genus Anaplasma - characteristics of Anaplasma and their vectors: a review

“…De Waal (2000) revealed that more than 99% of the total cattle population in South Africa was at risk. Rajput et al (2005) informed us that in Pakistan, Anaplasma parasites in buffalo and cattle Bubalus bubalis were 30% and 52%, respectively. It is estimated that in the United States alone, losses incurred by A. marginale may reach approx.…”

“…In spite of morphological differences, occurrence and virulence, A. centrale is closely related to A. marginale. A. centrale is the cause of mild anaemia in most cases of cattle infection (Kuttler, 1984;Kocan et al, 2003;Rajput et al, 2005). According to Theiler, A. centrale is less pathogenic to cattle than A. marginale but, most importantly, occasionally gives resistance against the latter.…”

Prevalence of theileriosis and babesiosis in cattle in Sirajganj district of Bangladesh

“…Tick transmitted haemoprotozoan diseases especially babesiosis, theileriosis and anaplasmosis are considered some of the major impediments in the health and productive performance of cattle (Rajput et al, 2005); affecting livestock industries in many parts of the world (Hourrigan, 1979). In some cases, ticks have been reported to cause lowered productivity, mortality (Niyonzema and Kiltz, 1986) and transmit the diseases (Norval et.…”
