A STUDY ON PREVALANCE AND CLINICO-PATHOLOGICAL FINDINGS OF PESTE DES PETITS RUMINANTS (PPR) AFFECTED GOATS IN DIFFERENT BREEDS REGISTERED TO PANCHLAISH UPAZILLA VETERINARY HOSPITAL AND THEIR RESPONSE TO ANTIMICROBIAL THERAPY

Abstract

The present study was conducted in the Panchlaish Upazilla Veterinary Hospital of Chittagong district during the period of July to September, 2013 to find out the clinicopathological findings and prevalence of Peste des petits ruminants (PPR) in goats, and to observe the response of PPR-goats to different treatments. During the course of study 202 goats were examined of which 98 were PPR positive. Diagnosis of a PPR case was made following the case history, physical examination, clinical examination, hematological examination, and post mortem examinations. Fecal samples from 40 randomly selected PPR-goats were examined for the presence of parasitic eggs. The results showes that the median age of PPR-goats was higher compared with the healthy ones. The median per-rectum temperature, heart and respiratory rates were also higher in the the PPR-postive goats. No significant difference was seen on its prevalence in goats belonging to Black Bengal or Jamunapari breeds. Its occurrence was also evenly seen in each of the three months - July, August and Septmber. But, prevalence of PPR was significantly higher in the non-vaccinated goats. Some hematological parameters – Hb (%), PCV, TEC (million/mm3), TLC ( thousand/mm3), ESR (0 hour), Lymphocyte (%), Monocyte (%), Eosinophil (%), Basophil (%) were lower in PPR-goats; in contrast, neutrophil count was higher in PPR- goats. Eggs of 5 major parasites namely, Haemonchus sp., Trichuris sp. Trichostrongylus sp., Strongyloides sp. and Oesophagostomum sp were commonly seen in the PPR-goats. The recovery rate from clinical signs was higher if the goats were treated with parenteral administration of oxytetracycline.
