Abstract
La presente investigación tuvo como objetivo determinar la frecuencia de enteroparásitos en Lactuca sativa L. “lechuga” var. Tropicana procedentes del mercado San Sebastián, distrito de Cajamarca – Perú (julio – diciembre, 2023); onstituyendo una investigación básica, descriptiva y transversal; donde la unidad muestral correspondió a la evaluación de cada ejemplar de “lechuga”, conformando la población la repetición de evaluaciones de cada unidad muestral, con lo cual la población tiende al infinito; y, de ella se extrajo una muestra aleatoria de 120 unidades, estimada mediante la fórmula estadística para población infinita y variable cualitativa dicotómica. Los datos obtenidos fueron analizados mediante estadística descriptiva e inferencial; a través de frecuencias porcentuales, test de proporciones, análisis de varianza, prueba de Fisher, correlación de Spearman y análisis multivariado; usando los Programas Minitab 18.0 y Past 4.1. Tomándose la decisión con 95 % de confianza. Los resultados mostraron quistes de Entamoeba hystolitica (39.17%), Entamoeba coli (13.33%), Blastocystis hominis (35%) y Giardia lamblia (13.33%); así como larvas de Strongyloides stercoralis (21.67%) y huevos de Hymenolepis nana (9.17%). Concluyendo que las muestras de Lactuca sativa “lechuga” var. Tropicana procedentes del mercado San Sebastián, distrito de Cajamarca – Perú presentan una alta frecuencia (61.67%) de enteroparásitos.
The objective of this research project was to determine the frequency of enteroparasites in Lactuca sativa L. “lechuga” var. Tropicana from the San Sebastián market, Cajamarca district – Peru (July – December, 2023); constituting a basic, descriptive and transversal research; where the sampling unit corresponded to the evaluation of each specimen of “lettuce”, the population forming the repetition of evaluations of each sampling unit, with which the population tends to infinity; and, from it, a random sample of 120 units was extracted, estimated using the statistical formula for infinite population and dichotomous qualitative variable. The data obtained were analyzed using descriptive and inferential statistics; through percentage frequencies, proportion test, analysis of variance, Fisher test, Spearman correlation and multivariate analysis; using Minitab 18.0 and Past 4.1 Programs. Making the decision with 95% confidence. The results showed cysts of Entamoeba hystolitica (39.17%), Entamoeba coli (13.33%), Blastocystis hominis (35%) and Giardia lamblia (13.33%); as well as Strongyloides stercoralis larvae (21.67%) and Hymenolepis nana eggs (9.17%). Concluding that the samples of Lactuca sativa “lettuce” var. Tropicana from the San Sebastián market, Cajamarca district – Peru present a high frequency (61.67%) of enteroparasites.
