Abstract/ Executive Summary:

An epidemiological investigation was carried out on common blood parasites (protozoa and rickettsia) in clinically suspected (febrile, anorectic, non responsive to antibiotics therapy) cattle attended at District veterinary hospital of Sirajgong. Total 60 cattle were examined for blood parasite (protozoa and rickettsia) infection. Giemsa’s stained were used on peripheral blood smears of suspected cattle. These slides were examined microscopically during September to October, 2004, of which 42 cattle (70 % of the total examined cattle) had Anaplasma infection (either Anaplasma marginale or Anaplasma centrale or both) and 2 cattle (3.3% of the total cattle) had Babesia infection but negative for other blood protozoal infection.

Keywords: Anaplasmosis, Babesiosis, Cattle, Occurrence

Location: Sirajgonj District Veterinary Hospital, Bangladesh

Start Date: 00-09-2004

End Date: 00-10-2004

Program Area: Animal Health and Management

Commodity: Cattle

Objectives:

To investigate present status of blood parasites in cattle in Bangladesh.

Methodology:

The study was carried out on 60 clinically suspected indigenous and crossbred cattle which were febrile, anorectic and non responsive to antibiotic therapy during September to October 2004 attended at Sirajgonj District Veterinary Hospital. Two or three thin blood smears by puncturing ear vein for each cattle were prepared. Smears were then fixed with methanol and stained with Giemsa’s stain and examined under microscope (100x) with immersion oil for the identification of blood parasites as described. The cattle were grouped into different age groups to determine the age and breed susceptibility of blood parasites.

Achievement/Findings:

The study revealed that occurrence of anaplasmosis found in age of 1 year and above and the higher occurrence (53.33%) was in cattle of more than 3 years old. Age wise occurrence of anaplasmosis recorded in this study support the report who recorded animal over 3 years age are highly affected by anaplasmosis. On the contrary, occurrence of babesiosis (3.33%) found in age of 6 months to 1 year in this study support the report who recorded the greater infection rate is in animal in the 6-12 months age group and infection is uncommon in animal over 5 years of age. it was revealed that crossbred cattle were mostly affected (58.33%) with anaplasmosis than indigenous cattle (11.66%). Breed susceptibility of anaplasmosis recorded in this study support the report. On the contrary, occurrence of Babesiosis (3.33%) was relatively higher in crossbred cattle. Breed susceptibility of Babesiosis recorded in this study support the report. From the above discussion, it was revealed that crossbred cattle were more susceptible to anaplasmosis and babesiosis.
