A Study on Prevalence and Clinico-pathological Features of Peste des petits ruminants (PPR) in Different Breeds of Goats Registered to Cox’sbazar Upazila Veterinary Hospital and their response to Antimicrobial therapy

Abstract

The study was conducted at the Upazila Veterinary Hospital, Cox’s bazar during July, August and December, 2012 to find out the clinico-pathological features and prevalence of Peste des petits ruminants (PPR) disease in terms of age, breed, sex, vaccinations, seasons and to observe the response of treatment using parenteral (I/M) oxytetracycline, oral/gut active sulphonamide and parenteral (I/M) sulphonamide. During the course of the study about 182 goats were examined in the hospital of which 87 of different breeds (Black Bangal, Jamunapari and Cross-bred ) were diagnosed with PPR. Diagnosis of PPR was made following the case history, physical examination, clinical examination findings and sometimes supported with hematological examination and postmortem examination results. The results showed that Black Bengal breeds were more prone (51%) to PPR than Jamunapari (47%) and Crossbred goats (43%). Non-vaccinated goats were more susceptible (65%) to PPR than vaccinated goats (26%) (p<0.05). The highest prevalence of PPR was recorded in December month (54%) than July (47%) and August (42%). PPR was proportionately but not significantly higher in female goats (50%) compared with male (47%) (p>0.05). In PPR positive goats the median age was higher (11month) than negative and the median temperature, heart rate and respiratory rate – all also were higher in the PPR-goats. All the haematological parameters except nutrophil counts decreased in PPR-goats. The success rate of recovery from the disease following the parenteral (I/M) use oxytetracycline was higher (55%) compared with the use of sulphonamide - either parenterally (40%) or orally (25%).
