| Abstract | Reliable environmental impact assessment regarding possible outcomes of the nearby fishponds is needed as manure of animals are applied directly for fishpondsand the locals need access to the safe drinking water for their health and region development.If the waterborne pathogens become more resistant to antibiotics, increase in the number of treatment failure cases of water-related diseases.Therefore,water sanitation is an important prevention tool in the rural area where public water delivery system is out of reach.According to the survey analysis, 42 households (out of 150 households) did not practice any sanitary method for drinking water while the rest used boiling and/or filtration technique in order to sanitize prior to the consumption. It was found that there was the statistically significant relation between people who were taking untreated water and the occurrence of diarrhoeal diseases (P=0.001).The drinking water pond of the study village is 3600 square feetin area and 10 feetdepth so that it is enough to support for the whole village throughout theyear. Dissolved organic carbon levels ofdrinking water pond is 3.98 mg/L (within the acceptable range) so that chlorination can be done to this pond. Regarding the microbial population of the water sources, fishpond water had higher number of heterotrophic bacteria than other sources. Among them, fishponds using pig manure and poultry farm over it had the highest number of heterotrophs with 1.24×105cfu/ml and 1.18×105cfu/ml respectively. HPC of the drinking water pond is 3.2×104cfu/ml so that this is much higher than UNEPA drinking water standard, however it was not chlorinated for eleven month from the date of my study. Antibiotic resistance is more common in isolates of fishpond origin than those of other sources (drinking water pond, ground water, stream water and channel water). Only two fishpond sources (using pig manure and poultry farm over it) had the antibiotic resistant isolates of Enterococcus faecalis,however those of isolates from other water sources were susceptible to five kinds of antibiotics(Amoxycillin, Vancomycin, Gentamycin, Tetracycline and Ciprofloxacin). Enterococcusisolates from fishpond using pig manure showed the resistance to Amoxicillin and Ciprofloxacin while the isolates from fishpond with poultry farm over it, were resistant to Tetracycline,Gentamicin and Ciprofloxacin. Enterococcusisolates of all water sources of this studywere found susceptible to Vancomycin. Escherichia coliwas detected only from the fishpond water using the pig manure and showed resistance to Amoxicillin and Tetracycline. |
