Background & objectives: Aeromonas species have been reported to cause various illnesses in humans such as wound infections, septicaemia, peritonitis and pneumonia. Their role in causation of cholera-like illness is also being increasingly recognized. This retrospective study was done to know the presence of Aeromonas as a cause of acute diarrhoea in a tertiary care hospital and to find the common species of Aeromonas causing diarrhoea and their antibiotic susceptibility patterns. Methods: Fifty isolates of Aeromonas were obtained over a period of 15 yr from 2000 to 2014 from patients of suspected acute gastroenteritis resembling cholera. Biotyping was done for 35 of these isolates available in culture collection, based on a panel of 13 biochemical reactions. Antibiogram was put up for all of these isolates by disk diffusion methods and interpreted according to the Clinical and Laboratory Standards Institute guidelines. Results: Of the 50 patients of Aeromonas-related acute gastroenteritis, 13 (26%) had typical features of cholera with rice water stools and severe dehydration. Eight patients (16%) had dysentery-like picture. One patient died of severe dehydration and septicaemia. The most common species were found to be Aeromonas caviae (34%) followed by Aeromonas veronii biovar veronii (29%), Aeromonas veronii biovar sobria (26%) and Aeromonas hydrophila (9%). All tested isolates were uniformly susceptible to cefepime, amikacin, azithromycin and meropenem; 14 per cent were susceptible to amoxicillin, 32 per cent to nalidixic acid, 60 per cent to co-trimoxazole, 54 per cent to ciprofloxacin, 60 per cent to ofloxacin, 74 per cent to chloramphenicol, 76 per cent to ceftriaxone, 74 per cent to cefotaxime, 88 per cent to gentamicin and 86 per cent to furoxone. Interpretation & conclusions: Aeromonas is an important, often neglected pathogen capable of causing a variety of gastrointestinal tract symptoms such as acute diarrhoea and dysentery and may even mimic cholera. It is, therefore, pertinent to recognize this pathogen as an important agent in the causation of severe diarrhoea.
