Ganga water is considered as sacred water and Hindu rituals from birth to death cannot be consecrated without Ganga water. The microbiological quality of holy river Ganga, life sustaining surface water resource for large population of northern India is adversely affected due to rapid industrialization and population growth. The current investigation surveyed on total number of 10 water samples collected from river Ganga flowing in different cities of India. The samples were analyzed for Most Probable Number (MPN) of coliforms and found to be in the range of 940 organisms to 33000 organisms per 100ml. Similarly, MPN Fecal coliform was done at an incubation of higher temperature, and resulted from lower of 109 organisms to a higher at 2800 organisms per 100ml of samples analyzed. The Ganga water samples also showed the presence of Escherichia coli and further its antibiotic susce...

There is no clear-cut evidence that the HPC bacteria as a whole pose a public health risk. Only certain members are opportunistic pathogens. Using the four-tiered approach for risk assessment from the National Academy of Sciences, hazard identification, dose-response modeling, and exposure through ingestion of drinking water were evaluated to develop a risk characterization, which estimates the probability of infection for individuals consuming various levels of specific HPC bacteria. HPC bacteria in drinking water often include isolates from the following genera: Pseudomonas, Acinetobacter, Moraxella, Aeromonas, and Xanthomonas. Other bacteria that are commonly found are Legionella and Mycobacterium. All these genera contain species that are opportunistic pathogens which may cause serious diseases. For example, the three nonfermentative gram-negative rods most frequently isolated in the clinical laboratory are (1) Pseudomonas aeruginosa, (2) Acinetobacter, and (3) Xanthomonas maltophilia. P. aeruginosa is a major cause of hospital-acquired infections with a high mortality rate. Aeromonas is sometimes associated with wound infections and suspected to be a causative agent of diarrhea. Legionella pneumophila causes 4%-20% of cases of community-acquired pneumonia and has been ranked as the second or third most frequent cause of pneumonia requiring hospitalization. The number of cases of pulmonary disease associated with Mycobacterium avian is rapidly increasing and is approaching the incidence of M. tuberculosis in some areas. Moraxella can cause infections of the eye and upper respiratory tract. The oral infectious doses are as follows in animal and human test subjects: P. aeruginosa, 10(8)-10(9); A, hydrophila, > 10(10); M. avium, 10(4)-10(7); and X. maltophilia, 10(6)-10(9). The infectious dose for an opportunistic pathogen is lower for immunocompromised subjects or those on antibiotic treatment. These bacteria have been found in drinking water at the following frequencies: P. aeruginosa, < 1%-24%; Acinetobacter, 5%-38%; X. maltophilia, < 1%-2%; Aeromonas, 1%-27%; Moraxella, 10%-80%; M. avium, < 1%-50%; and L. pneumophila, 3%-33%. These data suggest that drinking water could be a source of infection for some of these bacteria. The risk characterization showed that risks of infection from oral ingestion ranged from a low of 7.3 x 10(-9) (7.3/billion) for low exposures to Aeromonas to higher risks predicted at high levels of exposure to Pseudomonas of 9 x 10(-2) (98/100). This higher risk was only predicted for individuals on antibiotics. Overall, the evidence suggests that specific members of HPC bacteria found in drinking water may be causative agents of both hospital- and community-acquired infections. However, the case numbers may be very low and the risks represent levels generally less than 1/10,000 for a single exposure to the bacterial agent. Future research needs include (1) determining the seasonal concentrations of these bacteria in drinking water, (2) conducting adequate dose-response studies in animal subjects or human volunteers, (3) determining the health risks for an individual with multiple exposures to the opportunistic pathogens, and (4) evaluating the increase in host susceptibility conferred by antibiotic use or immunosuppression.

Increasing rates of antimicrobial resistance among E. coli is another furthermost fret worldwide. This problem is more traumatic when water bodies are getting contaminated with faecal pollution and inappropriate use of antibiotics that led to emergence of multi-drug resistant strains of this normal microbiota of human intestine. The current study dealt with the isolation of around thirteen Escherichia coli strains from seventy drinking water samples collected from different prominent locations of Noida region (Delhi). These strains were evaluated for their resistance and susceptibility patterns against eight commonly prescribed clinically-significant antibiotics viz, Amikacin, Ofloxacin, Gatifloxacin, Cefoperazone/Sulbactam, Gentamycin, Piperacillin/Tazobactam, Cotrimoxazole and Doxycycline HCL by disc diffusio...

(AI-21) a new soil borne isolate was characterized against food borne bacteria isolated from thirty-five food samples. Based on the morphological and biochemical characteristics, it was found that all food borne bacteria belong to Escherichia, Pseudomonas, Salmonella, Staphylococcus and Bacillus group of microorganisms. Colony morphology and biochemical characterization was the base of identification of actinomycete species. The actinomycete isolate was grown at a mass level by inoculum build up in mother flasks. Extraction of antibacterial substance from isolated actinomycetes was done by solventextraction method. Ethyl acetate extract exhibited activity against Staphylococcus sp. and Escherichia sp. The MICs of this extract was recorded in the range of 512 μg/ml to 2048 μg/mL. A maximum zone of 23.15mm was observed against Staphylococcus sp. The study not only targeted food borne isolates but also suggested how soil could be expl...

They are free-living, saprophytic, and abundant in soil, water, and colonizing nodulating plants. Actinomycetes assume a significant job in reusing squanders in the earth and they are additionally the makers of thousands of metabolic items, which display organic action. Due to the outstanding history of actinomycetes in the production of bioactive molecules for human interest, a large number of efforts have been made on the isolation, characterization and identification from terrestrial sources in the past half-decade. Secondary metabolites obtained from various potential strains of actinomycetes are very effective against Gram-positive and Gram-negative bacteria. Many researchers both nationally and internationally isolated this potential group of microorganisms from soil, water, sediment etc. and checked their potential antimicrobial activity. In the present review, antibiotic potential o...

The purpose of this study was to determine the ubiquity of the microbial contamination of the mobile phones that are possessed by general population of Delhi such as housewives, working people, shopkeepers, street vendors and health care staff. A total of 25 swab samples from mobile phones were collected for the enumeration, isolation and identification of the microorganisms. All the 25 mobile phones showed the presence of microbes. S. aureus was the most prevalent constituting 88% of the total samples. Other isolates that were identified were Pseudomonas aeruginosa, B. cereus and E.coli found in 8%, 80% and 4% of the mobile phone samples respectively. Mobile phones being the most common and useful devices are the carrier of pathogens that potentially put the general population at a health risk. Thus, hygienic practices should be incorpora...
