While African Health Sciences has been freely accessible online there have been questions on whether it is Open Access or not. We wish to clearly state that indeed African Health Sciences is Open Access. There are key issues regarding Open Access needing clarification for avoidance of doubt:
- 1. Henceforth, papers in African Health Sciences will be published under the CC BY (Creative Commons Attribution License) 4.0 International. See details on https://creativecomons.org/)

Diarrhoeagenic Escherichia coli isolated from children with acute diarrhoea at Rakai hospital, Southern Uganda
Abstract
Background: Diarrhoeagenic Escherichia coli (DEC) is a leading cause of childhood diarrhoea. This study estimated the prevalence of DEC and DEC pathotypes among children with acute diarrhoea in Southern Uganda.
Methods: A cross-sectional study was conducted on 267 children less than 5 years with acute diarrhoea, admitted to Rakai General Hospital in Southern Uganda. Faecal samples were collected from the children and processed for isolation of E. coli. The presence of DEC and the distribution of DEC pathotypes were determined by polymerase chain reaction.
Results: A total of 102 (38.2%, 102/267) children had DEC of various pathotypes – enteroaggregative E. coli (EAEC) (14.2%); enteropathogenic E. coli (EPEC) (6.7%); enterotoxigenic E. coli (ETEC) (6%); enteroinvasive E. coli (EIEC) (7.5%); enterohemorrhagic E. coli (EHEC) (3%); and cell-detaching E. coli (CDEC) (0.75%). The difference in the overall prevalence of DEC was not significant regarding HIV but individually, EAEC and CDEC were associated with HIV-positive status while ETEC was associated with HIV-negative status.
Conclusions: DEC is prevalent in children with acute diarrhoea in Southern Uganda and its identification in children should be considered among strategies for combatting childhood diarrhoea in Africa.
