The incidence of Aeromonas-associated diarrhoea in patients attending the hospital attached to the Dayanand Medical College, Ludhiana, India was investigated during May 1984-May 1987. Microbiological examination of single faecal samples from 2,661 patients showed the presence of various enteropathogens of which details of only Aeromonas isolations are given and discussed in the present article. A small control sample of 105 age-matched healthy volunteers were also examined. Only 55 patients (2.1% of all patients) showed Aeromonas spp. in their stool samples on culture. Aeromonas as a single pathogen was isolated from 37 patients and, from 18 patients it was mixed with other enteropathogens. Stools of healthy controls did not contain any pathogen. Seven of 25 isolates of A. caviae, all 18 isolates of A. sobria and all 7 isolates of A. hydrophilla were shown to be enterotoxigenic by rabbit ileal loop test. There was no immunological cross-reaction between Aeromonas enterotoxin and Escherichia coli labile toxin antiserum. The Aeromonas isolates were susceptible to most of the commonly used antimicrobial agents except ampicillin and cephalothin.

Diarrheal illness is a prominent public health worry in developing countries, resulting in high mortality among children. Sociodemographic characteristics and geographic settings are the main effective factors for the increased incidence of childhood diarrhea. is a neglected organism capable of causing dysentery and diarrhea.

Aeromonads have been isolated from varied environmental sources such as polluted and drinking water, as well as from tissues and body fluids of cold and warm-blooded animals. A phenotypically and genotypically heterogenous bacteria, aeromonads can be successfully identified by ribotyping and/or by analysing gyrB gene sequence, apart from classical biochemical characterization. Aeromonads are known to cause scepticemia in aquatic organisms, gastroenteritis and extraintestinal diseases such as scepticemia, skin, eye, wound and respiratory tract infections in humans.

We report the clinical findings, epidemiology, and risk factors for moderate-to-severe diarrhea (MSD) associated with Aeromonas species in children 0-59 months of age, from the Global Enteric Multicenter Study, conducted at three sites in south Asia and four sites in sub-Saharan Africa. Children with MSD were enrolled along with controls matched for age, gender, and neighborhood. Pooled, age-stratified conditional logistic regression models were applied to evaluate the association of Aeromonas infection controlling for coinfecting pathogens and sociodemographic variables.
