Identificación macroscópica de Stephanurus dentatus en cerdos faenados en el camal municipal del cantón Babahoyo

Stephanurus dentatus is a nematode parasite that commonly affects pigs, especially in tropical and subtropical regions. Infection by this parasite can cause significant lesions in organs such as the kidneys, liver, and lungs, in addition to causing confiscations in slaughterhouses. The objective of this study was to macroscopically identify the presence of S. dentatus in pigs slaughtered in the municipal slaughterhouse of Babahoyo, Ecuador. A post-mortem examination of the kidneys was performed on 300 samples of slaughtered pigs. Variables such as age, sex, breed, and origin were recorded. Through direct observation and incision of the kidneys, signs of the parasite were sought, such as cysts or anatomical alterations. The results of the study showed a total absence of positive cases among all the samples analyzed. The incidence was 0% across all categories. This contrasts with previous research reporting variable prevalence rates of swine parasitosis according to region. The lack of detection of S. dentatus could be attributed to the effectiveness of preventive measures implemented with the animals prior to slaughter, as well as favorable environmental conditions that influence the low local prevalence of the parasite. The absence suggests a positive scenario in terms of the control of parasitic diseases in the area. It is concluded that there was no presence of the parasite in the examined organs of the slaughtered pigs. It is recommended to continue with the health controls and complementary studies to confirm the epidemiological situation in the region.

El Stephanurus dentatus es un parásito nematodo que afecta comúnmente a los cerdos, especialmente en regiones tropicales y subtropicales. La infección por este parásito puede provocar lesiones significativas en órganos como los riñones, hígado y pulmones, además de ocasionar decomisos en mataderos. El objetivo de este estudio fue identificar macroscópicamente la presencia de S. dentatus en cerdos faenados en el camal municipal de Babahoyo, Ecuador. Se realizó un examen post mortem de los riñones en 300 muestras de cerdos sacrificados. Se registraron variables como edad, sexo, raza y procedencia. Mediante observación directa e incisión de los riñones se buscaron signos del parásito como quistes o alteraciones anatómicas. Los resultados del estudio evidenciaron la ausencia total de casos positivos entre todas las muestras analizadas. La incidencia fue de 0% en todas las categorías. Esto contrasta con investigaciones previas que reportan prevalencias variables de la parasitosis porcina según región. La falta de detección de S. dentatus podría atribuirse a la efectividad de medidas preventivas implementadas con los animales previos al sacrificio, así como a condiciones ambientales favorables que influyen en la baja prevalencia local del parásito. La ausencia sugiere un escenario positivo en cuanto al control de enfermedades parasitarias en la zona. Se concluye que no existió presencia del parásito en los órganos examinados de los cerdos faenados. Se recomienda continuar con los controles sanitarios y estudios complementarios para confirmar la situación epidemiológica en la región.
