Campylobacter-associated diarrhoea in Egyptian infants: epidemiology and clinical manifestations of disease and high frequency of concomitant infections.
A diarrhoeal disease survey in Alexandria, Egypt determined the prevalence, seasonality, and household risk factors for Campylobacter-associated diarrhoea in young children. The study population was 880 children (mean age = 9.8 months) presenting with diarrhoea at one of two hospitals. A control group consisted of 1,079 healthy children (mean age = 8.8 months) attending two nearby vaccination clinics. The overall isolation frequencies for Campylobacter spp. were 16.8% for cases and 6.4% for the comparison group (p = 1 x 10(-8)). Other enteropathogens detected in diarrhoeal stools were: rotavirus (28.6%), Giardia lamblia trophozoites (21.3%), enterotoxigenic Escherichia coli (8.7%), Entamoeba histolytica (3.9%), Salmonella spp. (2.7%), and Shigella spp. (1.8%). There were few or no isolates of Aeromonas spp., Vibrio spp., Yersinia spp., or Plesiomonas spp. Comparisons among cases showed that Campylobacter spp. isolations were more prevalent during the rainy season (p = 0.001) and positively associated with keeping fowl in the home (p = 0.003) or having an outdoor source of drinking water (p = 0.029). Among Campylobacter-positive diarrhoeal patients, 69.0% had faecal leukocytes present and 16.3% had bloody stools. Patients with Campylobacter-positive diarrhoeal stools were frequently co-infected with rotavirus (28.6%) or G. lamblia (24.5%).
