Abstract

SOLANO ALPIZAR, Luis Bernal. Epidemiology of anaerobic bacteria isolated in clinical samples at San Juan de Dios Hospital, San José, Costa Rica, during the 2014, 2015 and 2016 triennium. Rev. costarric. salud pública [online]. 2018, vol.27, n.2, pp.82-92. ISSN 1409-1429.

The epidemiology of the possible populations at risk of suffering an infection by anaerobic bacteria a national level is unknown, it should be encouraged the knowledge in the health services about this type of infections.

Anaerobic bacteria are related in hospital environments as an important cause of morbidity, which is why it is convenient to know the epidemiology and prevalence of species involved. In the Bacteriology Laboratory of the Hospital San Juan de Dios, for three years, a total of 1545 patients suspected of anaerobic microorganisms in prereduced media were analyzed, through a screening was reduced to a total of 469 possible samples, which were sent to the Anaerobic Bacteriology Research Laboratory (LIBA) for its corresponding identification. Throughout the epidemiological weeks of the three years were found on average of 1.77 confirmed cases / week, with a positive sex ratio in favor of men.

It was determined that only 245 of the samples sent had one or several strict anaerobic microorganisms representing 15.85% of the total, identifying 39 different species, in 306 isolated strains. The most important was the genus Bacteriodes, coming from the abdominal cavity followed by abscesses and skin wounds.

The present study aims to present data that support the clinical importance of the search for anaerobic microorganisms and that help the analysts of bacteriology to guide which are the main expected microorganisms in clinical samples, in addition to knowing the prevalence in general.
