Download ppt "Lecture 2 Microbial Indicators of Fecal and Other Types of Environmental Contamination envr 421 Mark. Coli (posses pili may be feces-specific May distinguish human from animal fecal contamination by group classification (II III human; I IV animal but, pigs may harbor groups II III, too Bacteroides fragilis phages: may be human feces specific; USA studies do not show human-specificity; concentrations. Molecular methods: human. V Constitute 1/3rd the mass of human fecal matter v Most are beneficial or essential in the gut; not pathogens v Some gut microbes are human pathogens; they cause disease. Very (too?) resistant spores (can persist for decades of centuries!) may be an indicator for protozoan cysts Bacteroides spp. Coli Total Coliforms Fecal Coliforms Escherichia coli All total and fecal coliforms and.

Candidate viral indicators OF fecal contamination OF water Coliphages: viruses (bacteriophages) infecting. Not all words have definitions within Google's databases. Enterococci: More feces-specific sub-set of FS: Enterococcus faecalis.

Human pathogens can be shed in human and animal feces. Easily detected/quantified by simple lab tests in a short time. The comprehensive system of environmental statistics is not needed just for assessing the current status of the environment, but also is essential for plan preparation, policy formulation, and sustainable development and the environment protection activities. Coli C Somatic Coliphage F Coliphage 23, methods to Detect Coliphages in Water Direct Plating Methods: water host medium Enumerative: Double or Single Agar Layer :.1-1 ml (DAL) or 10-100 ml SAL pour plate or plaque assay for development of phage plaques Quantal: Enrichment. Measuring all of these pathogens routinely for determining presence or absence or acceptable concentration is not possible. For humans, fecal sterols, etc. Limitations in Detecting Enteric (Fecal) Pathogens and their Indicators Some enteric pathogens have environmental origins besides feces; environmental reservoirs Some microbial indicators of fecal contamination have both fecal and non-fecal environmental sources Some fecal indicator microbe tests also detect similar non-fecal microbes; tests are not. Methods are not available to recover and measure some, Methods are available for others; they are technically demanding, some are slow to produce results and their costs are high. Related to the all-encompassing word, "Environment." It also illustrates the sweeping importance that is being attributed to the environment field as a whole. Microbial indicators have been used for 100 years (since late 1800s) to detect and quantify fecal contamination in water, food and other samples Concerns were for bacteria causing water-and foodborne illness, such as: Salmonella typhi : causes typhoid or enteric fever Vibrio cholerae : causes. In the literature of economic planning and policy making, having access to accurate and up-to-date statistics and information, which are the basis of decision-making, is a high priority among factors such as natural resources, financial resources, workforce, proper and progressive technology.
