Clinical Investigation of Anaplasmosis in Goat at UVH in Kashiani Upazilla, Gopalganj

Abstract

Anaplasmosis refers to a disease of ruminants caused by obligate intraerythrocytic organism Anaplasma sp. In this study blood samples were collected from 38 clinically sick goats with the history of anorexia, high body temperature, lethargy and diarrhoea that were brought to the UVH at Kashiani Upazilla in Gopalganj district between April 16, 2023 to June 08, 2023 for treatment purposes. After admission at UVH, initially all the goats were clinically examined for fever, respiratory and digestive tract disorders like, pneumonia, diarrhoea and bloat. In addition, superficial lymph nodes and external parasites were also examined. After careful clinical examinations high body temperature (above 103°F), anemia and dyspnea were recorded in all cases. Diarrhoea also observed in 8 goats with occulonasal discharges. Enlargement of suprascapular and prefemoral lymphnodes, and ectoparasite (Tick) was found in 12 cases. After the clinical examination procedures, a drop of blood was drained from the ear vein from all goats and blood smear was prepared and fixed with methanol. The purpose of the study was to determine the current state of Anaplasma sp. at UVH. After five minutes of methanol fixation, Giemsa stain was applied to the slides. As there was no facility for microscopic examination at the UVH, all the slides were carried to the Department of Pathology and Parasitology (DPP), CVASU after completing clinical placement. All the slides were examined carefully for the existence of blood protozoa in red blood cells using a microscope at a high magnification (10×100x) at DPP, CVASU. After microscopic examinations three of those samples were found positive (7.89%) for Anaplasma marginale. However, after clinical examinations and based on tentative diagnosis all the goats were treated with Oxytetracycline at 22 mg per kg body weight, Imidocarb dipropionate at 5 mg per kg body weight, Pheniramine maleate at o.5 mg per kg body weight and vitamin B-complex for 7 days and followed up for recovery stage. All the three goats that found positive for Anaplasma in microscopic examinations also considered for the same treatment and recovered from clinical symptoms which indicated that Oxytetracycline and Imidocarb medication was found to be effective against Anaplasma sp. in goat
