FRNA Bacteriophages as Viral Indicators of Faecal Contamination in Mexican Tropical Aquatic Systems
A particular challenge to water safety in populous intertropical regions is the lack of reliable faecal indicators to detect microbiological contamination of water, while the numerical relationships of specific viral indicators remain largely unexplored. The aim of this study was to investigate the numerical relationships of FRNA-bacteriophage genotypes, adenovirus 41, and human adenoviruses (H...
متن کاملApplication of library-independent microbial source tracking methods for identifying the sources of faecal contamination in coastal areas.
Faecal contamination sources were identified in coastal areas around the Guerande-Atlantique peninsula using two microbial source tracking (MST) methods: (i) Bacteroidales host-specific 16S rRNA gene markers measured by real-time PCR and (ii) F-specific bacteriophage (FRNAPH) genotyping. Both methods were used on 63 water samples from 7 water courses. HF183 marker and bacteriophage genogroup II...
متن کاملEvaluation of two library-independent microbial source tracking methods to identify sources of fecal contamination in French estuaries.
In order to identify the origin of the fecal contamination observed in French estuaries, two library-independent microbial source tracking (MST) methods were selected: (i) Bacteroidales host-specific 16S rRNA gene markers and (ii) F-specific RNA bacteriophage genotyping. The specificity of the Bacteroidales markers was evaluated on human and animal (bovine, pig, sheep, and bird) feces. Two huma...
متن کاملIsolation and Characterization of Lytic Bacteriophages from Wastewater against Listeria monocytogenes
Background and Aims: In the current study, two bacteriophages were isolated from the wastewater sources and characterized by lytic activity against the Listeria monocytogenes (L. monocytogenes) bacterium. Materials and Methods: 50 wastewater samples were collected from the disposal sites. The phages were isolated from the treated samples using the double agar overlay method with L. monocytoge...
متن کاملBacteriophage as an Index of Water Contamination
Because of technical difficulties of isolating pathogenic bacteria from waters (even from waters known to be contaminated fairly recently), the presence or absence of Bacterium coli in water supplies and the relative numbers of this organism if present are recognized as indications of the presence and degree of faecal pollution. This is based on the assumption that the more bacteria of intestin...
