  Objetivo: analizar la prevalencia de ehrlichiosis y anaplasmosis humana en los usuarios que asisten a un centro diagnóstico de laboratorio, Mérida 2017-2022. Metodología: enfoque cuantitativo, tipo documental, diseño retrospectivo transversal. La muestra estuvo compuesta por 638 usuarios que acudieron al centro diagnóstico durante el periodo de estudio. Resultados: sexo femenino (54,9%), edad 40,44 ± 19,41 años, edad del sexo masculino 35,71 ± 19,52 años, resultados positivos 54,9% (n=350), en 2018 se determinaron más casos (n=97) y en 2017 se observó un mayor porcentaje de positivos (66,9%), 53,4% de las pruebas de laboratorio procesadas fueron a pacientes provenientes del municipio Libertador, seguido de Campo Elías (12,1%), el mayor porcentaje de positivos fue de sexo femenino (56,6%), en edad de 31 a 35 años (11,1%), seguido del grupo de 46 a 50 años (10,0%). La curva ROC muestra que existe buena correspondencia entre el resultado de FCB y ehrlichia (Área=0,885; p-valor<,001), anaplasma-rickettsia (Área=0,617; p-valor<,001). La sensibilidad de la prueba de ehrlichia (77,7%) y anaplasma-rickettsia (23,4%). Conclusiones: más de la mitad de las pruebas de hematógenos fue positivo en el frotis de capa blanca, además cuatro de cada diez fueron casos de ehrlichia y uno de cada diez presentaron anaplasma-rickettsia. Se evidenció una sensibilidad y probabilidad de verdaderos positivos de ehrlichia de ocho casos de cada diez, mientras que al anaplasma-rickettsia hubo seis de cada diez verdaderos positivos por medio de la técnica de frotis de capa blanca.Objective: to analyze the prevalence of ehrlichiosis and human anaplasmosis in users who attend a laboratory diagnostic center, Mérida 2017-2022. Methodology: quantitative approach, documentary type, retrospective cross-sectional design. The sample was made up of 638 users who attended the diagnostic center during the study period. Results: female sex (54.9%), female age 40.44 ± 19.41 years, male age 35.71 ± 19.52 years, positive results 54.9% (n=350), in 2018 determined more cases (n=97) and in 2017 a higher percentage of positives was observed (66.9%), 53.4% of the laboratory tests processed were for patients from the Libertador municipality, followed by Campo Elías (12, 1%), the highest percentage of positives was female (56.6%), aged 31 to 35 years (11.1%), followed by the group of 46 to 50 years (10.0%). The ROC curve shows that there is good correspondence between the result of FCB and ehrlichia (Area=0.885; p-value<.001), anaplasma-rickettsia (Area=0.617; p-value<.001). The sensitivity of the test for ehrlichia (77.7%) and anaplasma-rickettsia (23.4%). Conclusions: more than half of the hematogenous tests were positive in the white layer smear, in addition four out of ten were cases of ehrlichia and one out of ten presented anaplasma-rickettsia. A sensitivity and probability of true positives for ehrlichia was evident in eight cases out of ten, while for anaplasma-rickettsia there were six out of ten true positives using the white layer smear technique.Recibido: 15-07-2024Aprobado: 08-09-2024Publicado: 01-11-2024
