Infecciones oportunistas de origen bacteriano más frecuentes en pacientes infectados con el virus de la inmunodeficiencia humana (VIH) Most frequent opportunistic infections from bacterial origin in patients infected by Human Immunodeficiency Virus (HIV)Infecciones oportunistas de origen bacteriano más frecuentes en pacientes infectados con el virus de la inmunodeficiencia humana (VIH) Most frequent opportunistic infections from bacterial origin in patients infected by Human Immunodeficiency Virus (HIV)Se realizó un estudio descriptivo, retrospectivo y transversal, con el objetivo de conocer los aislamientos bacterianos más frecuentes encontrados en diferentes muestras biológicas (esputo, sangre y orina) de pacientes con diagnóstico de VIH/SIDA, que asistieron a la consulta externa en el Hospital Abel Santamaría Cuadrado, en el período comprendido entre enero a diciembre de 2007. Se encontró que el mayor número de aislamientos fue a partir de muestras de esputos y Pseudomonas aeruginosa, resultando el microorganismo más aislado de todas las muestras (28,5 %). En la sangre la bacteria aislada con mayor frecuencia fue Staphylococcus epidermidis (48,5 %). En la orina, el microorganismo uropatógeno más frecuente encontrado fue Escherichia coli (43,5 %). Existió una especificidad de especie según localización anatómica en los pacientes VIH/SIDA. Palabras clave: staphylococcus epidermidis/ aislamiento & purificación, pseudomonas aeruginosa/ aislamiento & purificación, infecciones por escherichia coli/ diagnóstico, síndrome de inmunodeficiencia adquirida /complicaciones. ABSTRACT A descriptive, retrospective and cross-sectional study was conducted aimed at knowing the most frequent bacterial isolations found in different biological samples (sputum, blood and urine) of HIV/AIDS patients attending to the outpatient office at "Abel Santamaria Cuadrado" University Hospital, from January to December 2007. Most of the numbers of isolations were from sputum samples, resulting Pseudomonas aeruginosa the most isolated microorganism in all samples (28, 5%). In blood the isolated bacteria having the greatest frequency was Staphylococcus epidermidis (48, 5%). In urine, the uropathogenic microorganism most frequent found was Escherichia coli (43, 5%). Specificity of the species existed according to anatomic localization in HIV/AIDS patients. Key words: staphylococcus epidermidis/isolation & purification, pseudomonas aeruginosa/ isolation & purification, escherichia coli infections/diagnosis, Acquired Immunodeficiency Syndrome/complications.
