Assessment of bacterial flora in the nasal cavity of free range goats in Ibarapa East local Government, Oyo State, Nigeria

 

Abstract

The aerobic bacterial flora of the respiratory passageways were investigated using 144 goats slaughtered at Ibarapa East Local Government. Samples were collected aseptically from the nasal cavity for bacteriological examination. Standard microbiological techniques were used for isolation and identification of bacterial species. A total of 144 goats were selected for this study. Seventy-eight (54.2%) were adults while 66(45.8%) were young; 60(41.7%) were males while 84(58.3%) were females. All (100%) were West African Dwarfs. Of the 144 goats, only 21 (14.6%) were deemed to be apparently healthy. out of the 144 goats selected for this study, Bacteria organisms were not detected in 18.8%. E coli and Bacillus spp. were found in 47.9% and 22.9% of the goats while Proteus spp, D mirabilis and Moraxella spp. were found in 4.2%, 4.2% and 2.1% of the total no of goats selected respectively. All were citrate positive, ninety-four percent were catalase positive and 62.5% were indole positive while 16.7% and 6.3% were positive to urease and oxidase respectively. E. coli was the most predominant micro flora in the nasal passage of goat in Ibarapa East. Stress conditions may cause a disease state. Regular surveillance activities concerning goats must be encouraged. Veterinary extension services can be extended to farmers in order for them to embrace proper goat husbandry.
