Abstract
Through a year from April, 1999 to March, 2000, 20 samples, which consisted of raw sewage (2), chlorine-treated sewage (2), seawater (10) and naturally grown oysters (6), were collected monthly both from the sewage works at Mihama-ku, Chiba City and at a yacht harbor in Chiba City Bay, Japan. Astrovirus RNA were detected by reverse transcription-polymerase chain reaction (RT-PCR) and was typed by direct sequencing.<BR>Astrovirus positive products were detected from 9 samples (raw sewage; 1/2, chlorine-treated sewage; 2/2, seawater; 5/10 and oysters; 1/6) collected in April, 1999. In May, positive products were detected from 4 samples (raw sewage; 2/2 and seawater; 2/10). In June, only 1 positive product was detected from raw sewage. The number of positive samples showed a tendency to decrease and no positive products were detected from samples collected in July, 1999 to January, 2000. After that period, positive products were again detected from 3 samples (raw sewage; 1/2, chlorine-treated sewage; 2/2) collected in February, 2000. In March, the number of positive samples showed the peak and positive products were detected from 12 samples (raw sewage; 2/2, chlorine-treated sewage; 2/2, seawater; 7/10 and oysters: 1/6).<BR>Astrovirus positive products detected in April, May, June, July, 1999 and February, 2000 were classified into type 1 or 2 by sequencing, whereas in March, 2000 were type 1, 2, 3, 6 and 7.
