“…Although not isolated from this study, Vibrio cholerae, a pathogenic bacteria, has been isolated in other regions from aquaculture rearing facilities (Njoku et al, 2015) and has been implicated to account for several diarrhoea cases in Nigeria. For example, in the 2017 incident in the Ilorin metropolis, the culture positive rate of the Vibrio cholerae isolates was 41% (Amadu et al, 2021). Compared to the 78% level of occurrence reported by Borah et al (2010), Escherichia coli found in the present study was lower (8%) in both rearing enclosures and the regular trend recorded for other bacteria groups (TVC and TCC) was not witnessed for the faecal coliform group (Table 2 & 3).…”

Bacteriological and physico-chemical analyses of fish pond water are very important in aquaculture as they give insights into likely threats to aquaculture and associated personnel. Bacteriological and physico-chemical profiles of selected fish ponds in the Ilorin West area of Kwara State, Nigeria, were investigated to evaluate the water quality of rearing enclosures. Physico-chemical analyses revealed quality parameters were within the recommended range for aquaculture. Following bacteriological analyses of static water pond culture, the TVC and TCC showed temporal variations, with concentration increasing with sampling time. However, the FCC showed fluctuation. Totally, 8 bacteria groups were isolated from both rearing enclosures. Of these, Gram-negative bacteria showed dominance. In which 5 Gram-negative (Escherichia coli, Proteus spp, Serratia spp, Enterobacter spp, and Pseudomonas spp) and 3 Gram-positive (Staphylococcus spp, Streptococcus spp, and Bacillus spp) were encountered. Estimates of bacteria occurrence in both rearing facilities respectively gave: Staphylococcus spp (20%), Streptococcus spp (12%), Proteus spp (8%) Enterobacter spp (20%), Serratia spp (16%), Bacillus spp (9%), Escherichia coli (8%), Pseudomonas spp (7%) from earthen pond water sampled. While Staphylococcus spp (18%), Streptococcus spp (16%), Proteus spp (8%), Enterobacter spp (22)%, Serratia spp (8%), Bacillus spp (15%), Escherichia coli (8%), Pseudomonas spp (6%) from concrete water sampled. Conclusively, although there is the presence of bacteria groups of public health concern, the static water exchange provides benefits of natural processing of wastes and restoration of the pond ecosystem. Notably, the presence of Escherichia coli indicates the presence of pathogenic organisms of enteric origin. The presence of these organisms has been associated with a lack of tentative pond management and effective biosecurity procedures.

“…This is supported by different reports around the world. For example, the sero-prevalence of V. cholerae O1 was 60 to 86% in Bangladesh (38, 39), 100% in Pakistan) (40,41), and 59% in Nigeria (42,43). Evidences shown that in recent times, Ethiopia's con ict has erupted in Oromia and Amhara National Regional States.…”

Background: Cholera is an acute infectious disease caused by ingestion of Vibrio cholerae (V. cholerae) with contaminated food or water. Cholera remains a global threat to public health and an indicator of inequity and lack of social development. The aim of this study was to assess the prevalence and antimicrobial susceptibility pattern of V. cholerae from cholera outbreak sites in Ethiopia. Methods: Across-sectional study was conducted atOromia National Regional State, Amhara National Regional State and Addis Ababa City Administration. A total of 415 fecal samples were collected from the three regions. Two milliliter fecal samples were collected from each study participants. Culture, biochemical and serological tests were performed to identify and characterize V. cholerae. In addition, antibiotic susceptibility test was done. Data were registered in epi-enfo version 7 and analyzed by Statistical Package for Social Science version 25. Descriptive statistics were used to determine the prevalence of Vibrio cholerae. Logistic regression model was fitted and p-value <0.05 was considered as statically significant. Results: The prevalence of V. cholerae in the fecal samples was 30.1%. Majority of the isolates were from Oromia National Regional State 43.2 % (n=54) followed by Amhara National Regional State 31.2% (n=39) and Addis Ababa City Administration 25.6% (n=32). Most of the V. choleraeisolates were O1 serogroups 90.4% (n=113) and Ogawa serotypes 86.4% (n=108). Majority of the isolates were susceptible to ciprofloxacillin 100% (n=125), tetracycline 72% (n=90) and gentamycin 68% (n=85). More than half of the isolates were resistant to trimethoprim-sulfamethoxazole 62.4% (n=78) and ampicillin 56.8% (n=71). In this study, participants unable to read and write were about four times more at risk for V. cholerae infection (AOR: 3.8, 95% CI: 1.07 - 13.33). In addition, drank river water were about three times more at risk for V. cholerae infection (AOR: 2.8, 95%CI: 1.08- 7.08). Conclusion: The prevalence of V. cholerae from fecal samples was high. The predominant serogroups and serotypes were O1 and Ogawa, respectively. Majority of the isolates were susceptible to most of the antibiotics tested. Drinking water from river were the identified associated risk factor for V. cholerae infection. Protecting the community from drinking of river water and provision of safe and treated water could reduce cholera outbreaks in the study areas.
