“…The consumption of unhygienic drinking water and uses of unsafe water for daily purposes lead to the prevalence of diseases like diarrhea, typhoid, cholera, bacillary dysentery among the population [3]. The abundance and diversity of widely distributed microorganisms may be used as an indicator for the suitability of water [4]. Microbiological impairment of drinking, bathing, irrigation, or recreational water is commonly monitored using concentration of fecal indicator bacteria (FIB).…”

The present study was undertaken to investigate some water quality parameters (pH, BOD, DO and water temperature), anion concentration ( 524to the users of the river water but also poses risks for the aquatic organisms especially fish of the water bodies. So the occurrence of high bacterial load concluded that the water of Dhaleshwari river is polluted and unhygienic for drinking and even unsuitable for domestic purposes without proper treatment.

“…Coliform and faecal coliforms are established indicator organism is reliable and a very sensitive method for detection of faecal contamination in water due to sewage disposal or through other means. These microorganisms are widely distributed in nature; and their presence and diversity may be used as also a test for suitability of water (Okpokwasili and Akuugobi, 1996). Therefore, these indicator organisms have been recommended by regulatory agencies for water quality monitoring.…”

Water sample were collected from piped supplies, surface water and ground water sources in different locations of Lucknow city during summer, monsoon and winter season. Bacteriological quality of samples was determined by enumerating coliform isolated were subject to antibiotic susceptibility test with disc diffusion method. Maximum coliform and faecal coliform contamination were recorded during summer (67% and 75%) and monsoon (67% and 58.3%) while minimum during winter (50% and 50%). All the test isolates exhibited resistance (for nine antibiotics) was shown by river isolates. Antibiotic resistance index (ARI) ranged from 0.050 to 0.150 exhibiting the broad spectrum resistance for 3 to 9 out of 10 antibiotics tested. Occurrence of faecal pollution indicator organisms and multiple antibiotics resistance bacterial population in drinking water is alarming and a sign of potential health with therapeutic problems.

“…The coliform group (fecal and total coliforms) of bacteria are used as the principal indicators of quality of water for domestic, industrial and other uses. However, the interpretation of these classical indicators is known to be limited (Guillaud et al 1997;Medema et al 1997;Springthorpe et al 1997) and several authors have proposed supplementing the coliform index of water quality with Aeromonas levels (Seidler et al 1980;Baleux 1990, Miranda andCastillo 1996;Okpokwasili and Akujobi 1996).…”

Significance and suitability of Aeromonas hydrophila vs. fecal califorms in assessing microbiological water quality Djuikom, E.; Njiné, T.; Nola, M.; Kemka, N.; Zébazé Togouet, S. H.; Jugnia, Louis-B. ORIGINAL PAPERSignificance and suitability of Aeromonas hydrophila vs. fecal coliforms in assessing microbiological water quality E. Djuikom AE T. Njiné AE M. Nola AE N. Kemka AE S. H. Zébazé Togouet AE Louis-B. Jugnia Abstract We examined the significance and suitability of Aeromonas hydrophila versus fecal coliforms in assessing microbiological water quality. For this, we used the membrane filtration method to simultaneously estimate the abundance level of A. hydrophila and fecal coliforms in waters from the Mfoundi river watershed at Yaoundé, and compared how fluctuations in A. hydrophila abundance matched those observed with fecal coliforms index as an indicator of water quality in the system under study. Our results revealed that waters were not safe according to the standards for water quality established by the Word Health Organization (WHO). They also indicated the prevalence of A. hydrophila as compared to fecal coliforms, and suggested that water from the Mfoundi River and its tributaries could be classified as hypereutrophic based on the density of Aeromonas. Moreover, the spatial distribution of fecal coliforms and A. hydrophila exhibited similar trends within the different water bodies investigated, suggesting that A. hydrophila can be used as indicator of water quality in highly polluted waters. We concluded that waters from the Mfoundi River watershed at Yaoundé represent a great potential risk of infection for users, and foresee that the next challenge will be to determine, among other factors, the physico-chemical factors influencing the observed spatial distribution.
