Abstract

Urinary tract infections are a major cause of morbidity and mortality in Mozambique. They are sometimes treated empirically with nitrofurantoin. However, little is known about this antibiotic’s performance and bacterial resistance in the country. This study analyzed the results of nitrofurantoin sensitivity tests requested in the Central Hospital of Maputo during 2012 and 2013. As result, 181 samples were tested and most cases (66.9%) showed absolute sensitivity but there were considerable cases of resistance (29.8%). Morganella morganii was the only bacteria presenting no absolute or intermediate resistance. The sensitivity was also high in the case of Escherichia coli (90%) and Gram-negative bacteria (66.7%). Serratia marcescens was mostly resistant (64.3%). The remaining bacteria showed inconclusive results. Thus they shall be subjected to a sensitivity test before prescription. Factors such as seasonality, patients’ sex and urine transparency did not seem to be reliable indicators of microbial resistance in the urine. Yet, a longer time span (over 5 years) might be sufficient for the sensitivity profile to change.
