Abstract

BackgroundSheep constitute the second major component of livestock in Ethiopia. However, efficient utilization of this potential resource is hampered by combination of health problems, poor management and feed shortage. Haramaya district is one of the remote settings in Ethiopia where information about the livestock disease is not well documented. Hence this study was conducted to determine the causative agents and their antimicrobial susceptibility pattern of bacterial Pasteurella isolates among pneumonic ovine in Haramaya district, Eastern Hararghe, Ethiopia.ResultsOut of 256 samples examined, Pasterurella was isolated in 64 (25%), of which 38 (59.4%) were from lungs and 26 (40.6%) were from nasal cavities. 87.5% of the isolates were Mannheimia haemolytica and 12.5% were Pasteurella multocida. All of the isolates from the lungs were Mannheimia haemolytica whereas 69% of the isolates from nasals cavities were Mannheimia haemolytica. Age and body temperature were significantly associated with Pasteurella isolates from clinic (P < 0.05). Despite diverse in the site of origins, the isolates exhibited uniformity in sensitivity to a majority of the antibacterial agents. The most effective drug was Cholramphenicol (100%) followed by Sulfamethoxazole (89.1%) and Tetracycline (84.4%). Both species were completely resistant to Gentamycin and Vancomycin.ConclusionMannheimia haemolytica is the most common cause of ovine pneumonic pasteurellosis in the study area. The isolates were susceptible to limited antimicrobial agents. Therefore, the antimicrobial susceptibility test should be conducted before treatment, except for critical cases.

Highlights

Sheep constitute the second major component of livestock in Ethiopia
Study area The study was conducted at Haramaya district which is located in Eastern Hararghe Zone of Ethiopia, approximately 500 kms East of Addis Ababa
In conclusion, Pneumonic Pasteurellosis was the major disease of sheep in the area and M. haemolytica is the most common cause

Summary

Introduction

Sheep constitute the second major component of livestock in Ethiopia. efficient utilization of this potential resource is hampered by combination of health problems, poor management and feed shortage. Ethiopia lies within the tropical latitude of Africa and has an extremely diverse topography, a wide range of climatic features and a multitude of agro-ecological zone which makes the country suitable for different agricultural production system. This in turn has contributed to the existence of a large diversity of farm animal genetic resource in the country [3]. Despite the large livestock population of Ethiopia the economic benefits remain marginal due to prevailing diseases, poor nutrition, poor animal production systems, reproductive inefficiency management constraint and general lack of Veterinary core [4]
