Article Abstract:
Samples obtained from three water treatment plants by using treatments such as ozonation and biological filtration showed that all the samples contained Clostridium perfringens correlated with human enteric viruses, Giardia lamblia cysts and Cryptosporidium oocysts. The somatic coliphage counts were the only variable for the human enteric virus counts in settled water. Clostridium perfringens counts appear to be the ideal indicator for the inactivation and elimination of viruses, cysts and oocysts in drinking water treatment.

Article Abstract:
The determination of nucleotide sequence and cloning of a gene encoding a conjugated bile acid hydrolase (CBAH) from Clostridium perfringens in Escherichia coli shows that the gene product was related to previously characterized CBAH from Lactobacillus plantarum and a penicillin V amidase from Bacillus sphaericus. The gene product was purified from Escherichia coli and from this antibodies were produced in a rabbit. Immunoblot analysis confirmed the presence of proteins in Clostridium perfringens.

Article Abstract:
A study is conducted to address the occurrence of microbial indicators and clostridium perfringens in the untreated wastewater, watercolumn and sediments of the impacted area and drinking water treatment facility and distribution system at McMurdo Station. A wastewater treatment facility at McMurdo station has started operation and the data provides a baseline data set for monitoring the recovery of the impacted area.
