Abstract:
Samples offarm shrimp and pond water were collectedfrom Chi/aw. Total
bacterial counts of coliforms and Escherichia coli are reportedfor these samples.
Pathogens Vibrio parahaemolyticus, and Salmonella along with qualitative
microflora are also reported.
The bacterial counts of water rangedfrom 5 x 102/gto 8.8 x 103/g whereas
that of shrimp rangedfrom 2.0 x IO"/g to 9.0 x lO'/g. E. coli. ranged from 3 to
II/g for prawns 3/I00ml. to 49/I00ml. for pond water. Two shrimp samples
were positive for v. parahaemolyticus bacterial counts, coliforms or E. coli
counts did not show any correlation with water salinity, which rangedfrom 14-18
ppt,
Gram positive bacteria were predominant in shrimp and were represented
by Micrococci (41.8%). Corynebacterium (19.3%) and Bacillus (14.2%).
Common gram-negatives were Vibrios (19.2%) and Pseudomonas (5%).
