| Outline of Final Research Achievements |
In this study, the efficacy of anaerobic spores (Clostridium perfringens) as indicator for intestinal virus and microbial source tracking were investigated.
Concentrations of C. perfringens in coastal sea water were significantly correlated between Norovirus G2. C. perfingens were detected from all samples of Norovirus positive (11 samples), whereas, E. coli were only detected from only 4 of 11 Norovirus positive samples. Because of cpe positive C. perfringens isolates were detected from only human related wastewater samples, detection of cpe positive isolates were useful microbial source tracking indicator as human fecal pollution of surface waters. Concentration of Erythromycin in Handford Agar, which used for separation culture of C. perfringens from water samples, affected to growth and detection of C. perfringens.
