Water is the main source for life and also the most severe substance caused by pollution. The mandatory parameters for determining microbiological quality of drinking water are total non-fecal Coliform bacteria and Coliform fecal (Escherichia coli). Coliform bacteria are a group of microorganisms commonly used as indicators, where these bacteria can be a signal to determine whether a water source has been contaminated by bacteria or not, while fecal Coliform bacteria are indicator bacteria polluting pathogenic bacteria originating from human feces and warm-blooded animals (mammals) . The water inspection method in this study uses the MPN (Most Probable Number) method which consists of 3 tests, namely, the presumption test, the affirmation test, and the reinforcement test. The results showed that of 15 drinking water samples 8 samples were tested positive for Coliform bacteria with the highest total bacterial value of sample number 1, 15 (210/100 ml), while 7 other samples were negative. From 8 positive Coliform samples only 1 sample was stated to be negative fecal Coliform bacteria and 7 other samples were positive for Coliform fecal bacteria with the highest total bacterial value of sample number 1 (210/100 ml).

A cross-sectional study was conducted to determine the bacterial quality and antimicrobial susceptibility profiles of Enterobacteriaceae from drinking water in Bahir Dar city. A total of 140 water samples were collected in the wet and dry periods from springs (n = 4), reservoirs (n = 10) and private tap water at households (n = 126). Bacteriological analysis of water was conducted using multiple tube method. Overall, 21.4%, 18.6% and 17.8% of drinking water samples had total coliforms (TC), faecal coliforms (FC) and Escherichia coli, respectively. All spring water samples and 29.2% of private tap water had the highest TC load (18 most probable number/100 mL, 95% CI: 100). For FC, 81.4% of the drinking water supplies tested complied with both World Health Organization and Ethiopian Standards. High levels of resistance (98–100%) were observed for ampicillin by Enterobacteriaceae and Pseudomonas aeruginosa. All P. aeruginosa isolates and 20 (66.7%) of E. coli revealed multiple drug resistance. Enterobacteriaceae and P. aeruginosa isolates exhibited high levels of antimicrobial resistance. The bacterial quality of drinking water in Bahir Dar city was poor. Microbial surveillance and monitoring with periodic assessment on physical integrity of the water pipelines need to be undertaken.

Drinking water is a basic human need and must meet health requirements. Drinking water depots are a means of filling drinking water which is in the process of processing raw water using treatment and sterilization system. Drinking water depots as providers of drinking water must also meet the requirements of sanitation hygiene and personal hygiene management must also be maintained so that the water produced meets health requirements. The purpose of this study was to determine the effect of sanitation hygiene and personal hygiene management of refill drinking water depots on the quality of drinking water in terms of the Most Probable Number Coliform in Kediri. The research design used was analytic observational with cross sectional approach. The population of all refill drinking water depots in Kediri is 57, with the sampling technique that is Simple Random Sampling, where a portion of refill drinking water depots in Kediri are 50. Data is collected by check list, questionnaire and laboratory examination. The results showed that most of the hygiene sanitation of the drinking water depot had fulfilled the requirements of 77%, the drinking water personal hygiene depot was good as much as 85% and those who met the drinking water requirements were 70%. The results of the hygiene feasibility analysis showed the value of Sig 0.000<0.05 (R=0.935) means that there was an effect of hygiene sanitation quality with water quality in terms of the Most Probable Number Coliform. While the personal hygiene value of Sig 0.001 <0.05 (R = 0.528) indicates that there is a personal hygiene influence with water quality in terms of the Most Probable Number Coliform. The results of Logistic Regression test showed that there were effects of sanitation hygiene and personal hygiene management of refill drinking water depots with water quality in terms of the Most Probable Number Coliform with a significance value = 0.000 <a 0.05. This shows that the hygiene and the better personal hygiene at refill drinking water depots is increasingly fulfilling water quality requirements in terms of the Most Probable Number Coliform

Water safety and quality are fundamental to human development and well-being. Yet, at least 2 billion people are using a drinking water source contaminated with feces worldwide. This study was conducted to assess the types of water supply, storage and methods of purification of drinking water and to examine the bacteriological quality of supplied and drinking water at household level by most probable number (MPN) test in Makalbari area in Gokarneshwor Municipality, Kathmandu. A total of 80 households were selected using simple random sampling technique and two samples (one from main water supply and another from drinking water, n=160 water samples) were collected from each household. Ethical clearance was taken from the Nepal Medical College Institutional Review Committee. SPSS version 16.0 was used for statistical analysis. Majority of water supply samples 65 (81.2%) were from tap, 11 (13.8%) were from well and 4 (5.0%) samples were from bore well. Bacteriologically, of the total water supply samples, 34 (42.5%) samples were excellent, 16 (20.0%) samples were suspicious and 30 (37.5%) samples were unsatisfactory by MPN index quality. Most of the households stored drinking water in the tanks 34 (42.5%). Most of the water samples 29 (36.3%) were directly consumed from the water supply without purification. Among the directly consumed drinking water samples, 13 (44.8%) samples showed unsatisfactory MPN index. Most commonly used methods of water purification was filtration 21 (26.2%). Of the total drinking water samples, 33 (41.25%) samples were positive for total coliform. Thirty-two (40.0%) of the households reported diarrhea in past one year. A highly significant association was found between MPN index of drinking water and occurrence of diarrhea in the households. The quality of the most of the water samples from water supply and drinking water were unsatisfactory. Inspite of this, drinking water was not purified in some of the households. Moreover, few of the drinking water samples were not potable even after purification. Therefore, community should be made aware to improve quality of drinking water in households.

Water borne disease outbreaks associated with the drinking of unsafe water, containing pathogenic bacteria of fecal origin, is common in densely populated countries like Bangladesh. Present study was attempted to detect indicator bacteria from drinking water samples for the presumptive occurrence of fecal contaminations that are responsible for health associated problems. Therefore, a laboratory scale qualitative analysis through most probable number (MPN) method was employed. The indicator bacterium Escherichia coli were detected in 24 water samples out of 75 samples as revealed consequently by the presumptive, confirmed and completed tests of MPN method. Other Gram negative bacteria found in the samples included Alcaligenes faecalis, Pseudomonas spp., Klebsiella spp. and Proteus spp. Almost all of the identified bacteria showed resistance against commonly used antibiotics which is of significant health concern.

Drinking water contamination at the level of storage points poses a potential threat to the hospital environment as it can lodge some resistant pathogenic microorganisms that may cause hospital acquired infections. The study analyzed the physico-chemical and microbiological parameters of drinking water samples collected from the main water storage points from ten different local hospitals in and around Visakhapatnam using standard protocols. The samples were processed within 2 hours after collection and the identification of pathogenic bacteria was performed through Most Probable Number (MPN) method, cultural characteristics and biochemical reactions. Antimicrobial susceptibility test was carried out by Agar well diffusion method according to Clinical and Laboratory Standards Institute (CLSI) guidelines. In the current study, all the tested ten water samples cross the permissible MPN count indicating that the water samples were not potable for drinking purpose and needs further and better disinfection procedures. Among the isolated pathogens, Pseudomonas aeruginosa exhibited highest sensitivity to antibiotics imipenem (50%) and tetracycline (50%) and resistance towards other tested antibiotics, whereas E.coli showed 100% susceptibility to imipenem and 100% resistance to ampicillin. Out of ten isolated strains of Proteus species, majority have exhibited 80% resistance to ampicillin and Tetracycline and 80% sensitivity to imipenem. All the four isolated strains of Shigella species expressed 100% resistance to ampicillin and 75% sensitivity to imipenem, meropenem, azithromycin, linezolid, vancomycin and chloramphenicol. The five isolated strains of Vibrio species showed 100% resistance to ampicillin and 80% sensitivity to imipenem, doxycycline and tetracycline. Greater part of the isolates were multidrug resistant isolates.

Quality of drinking water and juice is very important because if the quality deteriorates by the contamination of faecally originated microorganisms, it may cause serious diarrhea associated problems leading to death. In overpopulated countries like Bangladesh, this is a common scenario to experience diarrheal diseases due to drinking non-potable water as well as contaminated fresh juices. Present study was conducted to determine the quality of drinking water and juice by detection of indicator bacteria Escherichia coli by MPN (Most Probable Number) method which was performed by three consecutive steps including presumptive test, confirmed test and completed test. Other gram negative bacteria were also identified by biochemical methods. The indicator bacterium Escherichia coli was detected in two water samples out of 15 samples and one juice sample out of fifteen samples respectively during the MPN test method. Other Gram negative bacteria found in both water and juice samples included Klebsiella spp., Alcaligenes spp., Pseudomonas spp. and Proteus spp. The quality of drinking water and juice was found to be good in Bangladesh but proper hygiene should be maintained more strictly to avoid the contamination by other gram negative bacteria which are also capable of causing disease.
