In-vitro Antimicrobial Resistance of Shigella and Salmonella species Recovered from Abattoir effluent in Afikpo, South Eastern Nigeria

Physico-chemical and Bacteriological Quality of an Abattoir Wastewater Discharged into Water Bodies in Ibadan, Nigeria and drug resistant profile of isolated Salmonella species

“…However, the count was higher and not in agreement with the report of the study carried out in a private and government-approved abattoir in Benin, Edo state, a city in the south-south Nigeria [20] where a count of 9.8×10 5 cfu/ml and 4.1×10 5 cfu/ml respectively were obtained. The report of this study also disagrees with the result obtained from another recent abattoir study from Afkipo, south east Nigeria where 1.00×10 4 -1.77×10 4 was reported [28]. Meanwhile, the drainage total bacterial count was slightly higher than that of the slaughter slab.…”

“…While the later study was on remnant foods and wastewater from restaurants, the present study was on abattoir wastewater. The result of the resistance to ceftriaxone in this study was in total disagreement with other studies that reported 0% resistance [28,34]. Meanwhile, resistance to ciprofloxacin (10.4%) was low which is similar to recent observations in some other related studies [28,34] but completely disagreed with the recent report [36] in Ethiopia who reported 100% Salmonella resistance in a study that examined samples from dairy farm, abattoir and humans.…”

Furthermore, resistance (41.7%) of the strains of Salmonella in this study to chloramphenicol is higher than the 10.0%, 16.7% and 25.0% previously reported [30,34,36] but lower compared to the 62.3% reported from studies on clinical isolates [32].…”

“…The isolation of Salmonella species from the present study is consistent with the reports of previous studies in abattoir wastewater both in Nigeria and Kenya [28,30]. This observation is not strange as Salmonella is a pathogen that persists and able to survive and proliferate in different environment [28].…”

“…This observation is not strange as Salmonella is a pathogen that persists and able to survive and proliferate in different environment [28]. Although, resistance (68.8%) of Salmonella strains in this study to tetracycline is a bit high, it is however lower compared to the 90% and 80% reported in similar studies carried out in Nsukka, South Eastern, Nigeria [31] and Nairobi, Kenya [30] respectively.…”
