Abstract
The total viable bacterial populations in the oysters and the sea water from the edible
oyster farm at Tuticorin were · in the range of 103 to 104 per ml and 102 to
103 per ml respectively. The maximum most probable number of faecal
coliform recorded during the one year period of study of both the oysters and seawater
were 33 per 100 ml. Pathogenic bacteia (Salmonella sp., Vibrio cholerae, coagulase
positive staphylococci and faecal streptococci were absent in oysters and farm water.
Study of 197 (98 taken from oyster liquid and 99 from oyster farm water) randomly
isolated cultures indicated that gram negative asporogenus rod-like bacteria of the Vibrio,
Flavobacterium, Achromobacter and Pseudomonas gcoups were the dominant flora of
the oyster liquid as well as seawater.
