Aeromonas species and Plesiomonas shigelloides in diarrhoea in Goa.

Sixty six strains (1.9%) of Aeromonas species and 7 strains (0.2%) of Plesiomonas shigelloides were isolated from 3484 stool/rectal swabs from cases of diarrhoea during the study period of four years from August 1986 to July 1990 in Goa. Although the selective medium (Ampicillin sheep blood agar) was not used for the isolation of Aeromonas, an increase in the rate of isolation of Aeromonas from 0.2% in the year 1986 to 6.0% in 1990 was observed. Stool samples from 100 controls (patients without diarrhoea) examined in the year 1989 did not yield either of the pathogens.
