Characterization of <i>Enterococcus</i> species isolated from abattoir environment in Benin city, Nigeria

Abstract

Enterococci are primarily inhabitants of the intestinal mucosa of animals and humans; however, they can also be recovered from water, soil, plants, insects and fermented food products. The aim of this study was to carry out quality indices survey for Enterococcus species from the abattoir environment in Benin City, Edo State, Nigeria. A total of 36 samples were obtained from two different abattoirs which comprised of water source (n = 12), effluent from point of usage (n = 12) and effluent from point of discharge (n = 12) between February and July, 2017. Physicochemical variables of the effluents were assessed using standard analytical techniques. The isolation of Enterococcus isolates was carried out using standard culture-based techniques. Analytical profile index 20E (API 20E) was used to confirm the identity of the Enterococcus species. Antimicrobial susceptibility profile of the Enterococcus species was determined using disk diffusion method. The mean ranges of physicochemical parameters of the water samples were: pH (5.36 ± 0.85-7.35 ± 0.28), phosphate (0.39 ± 0.31-21.28 ± 0.01 mg/L), dissolved oxygen (0.83 ± 1.94-6.13 ± 0.13 mg/L) and chemical oxygen demand (COD) 7 (35.66 ± 0.13-797.10 ± 0.35 mg/L). The mean range of mesophilic bacteria count was (6.

Bacterial contamination of chicken meat in slaughterhouses and the associated risk factors: A nationwide study in Thailand

“…found in this study were consistent with those observed in Slovakia and Brazil which ranged from 1.8 to 50.9% [ 41 , 42 ]. Those might be indicated contamination from slaughtering equipment, wastewater, and slaughterhouse environment [ 43 – 45 ]. Our findings showed the proportion of coliforms and E .…”

Vancomycin-Resistant Enterococci (VRE) in Nigeria: The First Systematic Review and Meta-Analysis

“…Most of the studies were reported from the South-West region ( n = 8) [ 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ]. Other studies include the North-Central region ( n = 3) [ 25 , 26 , 27 ], South-East region ( n = 3) [ 28 , 29 , 30 ], South-South ( n = 4) [ 31 , 32 , 33 , 34 ], and North-West region ( n = 1) [ 35 ]. No study was reported in the North-East region of the country.…”
