title: Seasonal fluctuations in the occurrence of enteroinvasive Escherichia coli diarrhoea.
abstract: Enteroinvasive Esch. coli (EIEC) was implicated in 2.1 per cent (57 out of 2661) diarrhoeal patients investigated at Ludhiana (Punjab). The predominant serogroups isolated were 028, 0147, 0124 and 0112. High prevalence of EIEC infection was noticed among infants (50.6%) followed by children up to 10 yr (19.3%). The peak incidence (24.5%) occurred during the hot and dry month of May as compared to 1.7 per cent in February. The disease incidence was positively correlated with mean minimum temperature and mean maximum temperature. All strains gave Sereny's test positive and were mostly susceptible to cephalothin, gentamicin, nalidixic acid, furazolidine and neomycin.
