Las bacterias anaerobias están relacionadas en los medios hospitalarios como causa importante de morbilidad, razón por la cual es conveniente conocer la epidemiologia y prevalecía de especies involucradas. En el Laboratorio de Bacteriología del Hospital San Juan de Dios, durante tres años, se analizaron un total de 1545 pacientes sospechosos de microorganismos anaerobios en medios prerreducidos, mediante un tamizaje se redujeron a un total de 469 posibles muestras, las cuales, fueron enviadas al Laboratorio de Investigación en Bacteriología Anaerobia (LIBA) para su correspondiente identificación. A lo largo de las semanas epidemiológicas de los tres años se encontraron en promedio de 1.77 casos confirmados / semana, con razón de sexo positiva a favor de los masculinos. Se determinó que solo 245 de las muestras enviadas presentaban uno o varios microorganismos anaerobios estrictos representando un 15.85% del total, identificándose 39 especies diferentes, en 306 cepas aisladas. Las mayormente importante fue el género Bacteriodes, provenientes de cavidad abdominal seguido de abscesos y heridas de piel. El presente estudio tiene como objetivo presentar datos que respalden la importancia clínica de la búsqueda de microorganismos anaerobios y que ayuden a los analistas de bacteriología a guiar cuales son los principales microorganismos esperables en muestras clínicas, además de conocer la prevalencia en general.]]></p></abstract>

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.]]></p></abstract>
