“…Out breaks of water borne diseases continues to occur throughout the world but are especially serious in the developing countries, disease contacted through drinking water kill about 5 million children annually and make 1/6 th of the world population sick [5,10]. The human pathogens that are present in drinking water includes; Salmonella species, Shigella species, pathogenic Escherichia coli, Vibro cholera, Yersinia entercolitica, Campylobacter species, Klebsiella and various viruses such as Hepatitis A, Hepatitis E, Rota virus and parasites such as Entamoeba histolytica, and Giardia species [15,16]. To curb this health problem of unsafe water, bottle water was introduced, but only individuals who have good financial status can afford this product.…”

This study evaluated the physico-chemical and the bacteriological quality of five different sources of drinking water in Calabar metropolis, Nigeria, to give a fair geographical representative of the town and to contribute to our understanding of the quality of drinking water in the metropolis. The physico-chemical characteristics such as pH, temperature, turbidity, conductivity, colour, Iron, dissolved oxygen, Calcium, Magnesium, alkalinity, total hardness, Manganese, Sulphate, Chloride, Phosphate, Sodium, Zinc, Copper, total dissolved solid, Nitrate, Nitrite, Ammonia, Ammonium and Potassium were determined following the procedures prescribed by American Public Health Association Standard Method. The bacteriological analysis was carried out using the standard microbiological standard for analysis of water for total and faecal coliform count. The mean temperature of the evaluated waters ranged from 23.03°C-29.3°C, mean pH ranged from 4.37-6.76, while turbidity had a mean range of 0.16 NTU-4.13 NTU. Conductivity ranged between 39.29 µs/cm - 120.7 µs/cm, dissolved oxygen with 13.30 mg/L - 4.19 mg/L, total dissolved solids ranged from 72.4 mg/L -23.5 mg/L, while the mean for iron concentration ranged from 0.12 mg/L - 0.99 mg/L. Similarly, the mean for total hardness was 34.2 mg/L - 17.1 mg/L and 7.93 mg/L - 6.71 mg/L for total alkalinity. Others includes Manganese (0.88 mg/L - 0.02 mg/L), Magnesium (16.5 mg/L - 9.9 mg/L), Calcium (9.77 mg/L - 7.20 mg/L, Nitrate (14.6 mg/L - 3.66 mg/L), Nitrite (0.076 mg/L -0.009 mg/L), Ammonia (0.89 mg/L - 0.25 mg/L), Ammonium (0.52 mg/L - 0.013 mg/L), Zinc (1.01 mg/L - 0.34 mg/L), Chloride (5.73 mg/L - 0.364 mg/L), Fluoride (0.76 mg/L - 0.277 mg/L), Copper (0.61 mg/L - 0.18 mg/L), Sodium (2.73 mg/L - 0.180 mg/L), potassium (5.73 mg/L - 2.0 mg/L), Sulphate (14.8 mg/L - 3.69 mg/L and Phosphate with 4.8 mg/L - 3.69 mg/L. The total coliform count for bottled water ranged between 2.00 cfu/100 mL – 19.00 cfu/100 mL, the total coliform range for sachet water were 6.00 cfu/100 mL and 15.00 cfu/100 mL and no faecal coliform was detected. Public water had no growth at all, the stream and borehole bacteriological analysis ranged from 27x101 cfu/ mL - 55x101 cfu/mL and 12 cfu/100 mL - 33 cfu/100 mL for total coliform respectively. Faecal coliform ranged from 15x101 cfu/ mL - 52x101 cfu/ mL for stream and 9.00 cfu100/ mL – 16.00 cfu/100 mL for borehole. A total of seven (7) different bacteria species were isolated from the sampled drinking water sources. These included Proteus spp., Streptococcus spp., Enterobacter spp., Pseudomonas spp., E.coli, Chromobacter spp., Salmonella spp. and Enterococcus spp. This study reveals a high level of poor quality sources of water in the metropolis and makes need for urgent health intervention.

“…1 shows that three areas of application account for over two thirds of all research in the field of pathogen detection. These are the food industry (Leonard et al, 2003;Patel, 2002), water and environment quality control (Emde et al, 1992;Theron et al, 2000) and clinical diagnosis (Atlas, 1999). The remaining efforts go into fundamental studies (Gao et al, 2004;Herpers et al, 2003), method performance studies Taylor et al, 2005) or development of new applied methods (Yoon et al, 2003;Ko and Grant, 2003).…”

“…(1)(2)(3). Contamination by human and animal waste can serve a source of pathogenic bacteria causing different diseases like a dysentery, diarrhea, typhoid, salmonellosis, shigellosis, listeriosis, viral infections like Hepatitis A, parasitic infections and so on (12)(13)(14)(15)(16). Some pathogenic microorganisms contaminating the water include Salmonella spp., Escherichia coli, Listeria spp., Shigella spp., Vibrio spp., Yersinia spp., Campylobacter spp., Hepatitis A and Hepatitis E virus, some parasites etc.…”

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.
