ABSTRACTPersistence of Campylobacter sp and its biofilm forming ability was assessed in two poultry abattoirs at two weeks intervals. Average prevalence (63.75%) of Campylobacter spp. was observed on assessing a total of 160 samples collected from the surfaces of packaging table (80%), dressing table (75%), floor source (70%) and washing table (30%). Biofilm assessment formed by Campylobacter jejuni within 5-days at 37°C were in decreasing order of washing table > packaging table > dressing table > floor. An average rate (19.6%) of isolates to develop biofilm observed in both sites was considered relatively low. Absorbance value (Optical Density-OD590nm) of formed biofilms ranged from 0.483 – 0.952. Wastewater from the facilities showed higher TDS (643 – 820 mgl−1), TSS (1200 – 1775 mgl−1), COD (152 – 141 mgl−1) and BOD (30.3 – 32.5mgl−1) than the WHO standards of 500 mgl−1, 100 mgl−1, 10 mgl−1 and 6 mgl−1 respectively. This is a clear indication of heavy microbial presence in the wastewater. Total bacterial count (TBC) was slightly higher in site A (4.4 × 105 CFU/ml) than site B (3.5 × 105 CFU/ml). Efficiency index ratio (≈/> 1) observed in all tested drugs suggests their effectiveness in campylobacteriosis management. Decreasing drug sensitivity pedigree was observed with streptomycin > erythromycin & gentamincin > tetracycline & neomycin > penicillin > riphapicin & ampicillin > norflaxicin & cephalexin. These results of frequency and biofilm forming tendencies of Campylobacter spp. observed in this study can be of value in checkmating campybacteriosis outbreak from poultry abattoir facility.
