Abstract

<jats:title>Abstract</jats:title> <jats:sec> <jats:title>Background</jats:title> <jats:p>Shigellosis remains considerable public health problem in some developing countries. The nature of <jats:italic>Shigellae</jats:italic> suggests that they are highly adaptable when placed under selective pressure in a human population. This is demonstrated by variation and fluctuations in serotypes and antimicrobial resistance profile of organisms circulating in differing setting in endemic locations. Antimicrobial resistance in the genus <jats:italic>Shigella</jats:italic> is a constant threat, with reports of organisms in Asia being resistant to multiple antimicrobials and new generation therapies.</jats:p> </jats:sec> <jats:sec> <jats:title>Methods</jats:title> <jats:p>Here we compare microbiological, clinical and epidemiological data from patients with shigellosis over three different periods in southern Vietnam spanning14 years.</jats:p> </jats:sec> <jats:sec> <jats:title>Results</jats:title> <jats:p>Our data demonstrates a shift in dominant infecting species (<jats:italic>S. flexneri</jats:italic> to <jats:italic>S. sonnei</jats:italic>) and resistance profile of the organisms circulating in southern Vietnam. We find that there was no significant variation in the syndromes associated with either <jats:italic>S. sonnei</jats:italic> or <jats:italic>S. flexneri</jats:italic>, yet the clinical features of the disease are more severe in later observations.</jats:p> </jats:sec> <jats:sec> <jats:title>Conclusions</jats:title> <jats:p>Our findings show a change in clinical presentation of shigellosis in this setting, as the disease may be now more pronounced, this is concurrent with a change in antimicrobial resistance profile. These data highlight the socio-economic development of southern Vietnam and should guide future vaccine development and deployment strategies.</jats:p> </jats:sec> <jats:sec> <jats:title>Trial Registration</jats:title> <jats:p>Current Controlled Trials ISRCTN55945881</jats:p> </jats:sec>
