Detection of somatic coliphages
as indicators of faecal contamination in estuarine waters.
coli, FE, and somatic coliphage
in leachate samples after log-transformation of the raw data plus 1 were plotted against time.
Drinking water (2 L) and surface (1 L) water samples were assayed for coliphage
by the two-step enrichment method (U.
removal from the filter backwash was 97 and 35% during 1999 and 2000, respectively.
were monitored as evidence of fecal contamination.
Ten microliters was used for bacteriophage enumeration, as described above for somatic coliphages
, to verify that phages were present in the purified fraction.
and indigenous phage in Mamala Bay, Oahu, Hawaii.
A similar result has been reported for the blue mussel, Mytilus edulis, and the hard clam, Mercenaria mercenaria, concerning the depuration of coliphages
and Escherichia coli (Richards 1988, Power & Collins 1990).
Then, viral samples in the liquid phase were subjected to plaque assay for coliphages
at 37[degree]C and for [phi]6 at 26[degree]C.
These samples were analyzed in a nearby mobile laboratory for six microbiological parameters: Escherichia coli [International Standardization Organization (ISO) 1998b], intestinal enterococci (ISO 1998a), Clostridium perfringens (Council of the European Union 1998), somatic coliphages
(ISO 2000), aeromonads (Schulze 1996), and pyocyanine-positive Pseudomonas aeruginosa (Deutches Institut fur Normung, European Normalization 2002).
En esta investigacion se plantea la utilizacion del metodo ARCAT (A Rapid Coliphage
Analysis Techinique) para el aislamiento de los virus que infectan a la bacteria Escherichia coli.
During this period, results of environmental monitoring and beach water sampling for FRNA coliphages
by culture and Bacteroides by PCR in Roger Fujiokas laboratory at the Water Resources Research Center also showed that the beaches were contaminated for up to two days but not four days after the sewage spill had stopped (Fujioka, Betancourt, & Vithanage, 2006).
