Relationship between fecal egg count, parasite load, and histopathological findings in the pancreas of cattle naturally infected with Eurytrema coelomaticum
Eurytrematosis, a disease caused by Eurytrema spp., primarily affects the pancreas of mammals, including cattle. Although common in Africa, Asia and South America, Eurytrema coelomaticum has recently been detected in Argentina. The present study aimed to evaluate the relationship between parasite lo...

| description | Eurytrematosis, a disease caused by Eurytrema spp., primarily affects the pancreas of mammals, including cattle. Although common in Africa, Asia and South America, Eurytrema coelomaticum has recently been detected in Argentina. The present study aimed to evaluate the relationship between parasite load, fecal egg counts (EPG) using two diagnostic techniques (BST and OST), and histopathological lesions in cattle naturally infected with Eurytrema. A total of 120 cattle from an endemic area were selected for the study, with both pancreatic and fecal samples collected for parasitological and histopathological analysis. Histopathological lesions were classified into three grades based on the severity of pancreatic damage. The results demonstrated a significant difference between the parasitic load and the severity of pancreatic lesions (P= 0.001). Both diagnostic techniques demonstrated a significant difference between parasite presence and lesion severity; however, the OST showed higher sensitivity (88 %) and fewer false negatives (12 %) compared to the BST, which exhibited 65 % sensitivity and 35 % false negatives. Histopathological findings revealed more severe lesions, such as fibrosis and interstitial inflammation, in animals with higher parasite loads. These results emphasize the importance of combining reliable diagnostic techniques like OST with histopathological analysis to improve the understanding and management of eurytrematosis in cattle. The findings provide valuable insights into the disease's impact and suggest strategies for controlling its effects on livestock health and productivity. |

La eurytrematosis, una enfermedad causada por Eurytrema spp., afecta principalmente al páncreas de mamíferos, incluido el ganado bovino. Aunque es común en África, Asia y Sudamérica, Eurytrema coelomaticum se ha detectado recientemente en Argentina. El presente estudio tuvo como objetivo evaluar la relación entre la carga parasitaria, el recuento de huevos fecales (HPG) mediante dos técnicas de diagnóstico (BST y OST) y las lesiones histopatológicas en ganado bovino infectado naturalmente con Eurytrema. Se seleccionó un total de 120 bovinos de una zona endémica para el estudio, y se recolectaron muestras pancreáticas y fecales para su análisis parasitológico e histopatológico. Las lesiones histopatológicas se clasificaron en tres grados según la gravedad del daño pancreático. Los resultados demostraron una diferencia significativa entre la carga parasitaria y la gravedad de las lesiones pancreáticas (P = 0,001). Ambas técnicas de diagnóstico demostraron una diferencia significativa entre la presencia de parásitos y la gravedad de las lesiones. Sin embargo, la OST mostró una mayor sensibilidad (88 %) y menos falsos negativos (12 %) en comparación con la BST, que presentó una sensibilidad del 65 % y un 35 % de falsos negativos. Los hallazgos histopatológicos revelaron lesiones más graves, como fibrosis e inflamación intersticial, en animales con mayor carga parasitaria. Estos resultados enfatizan la importancia de combinar técnicas diagnósticas confiables como la OST con el análisis histopatológico para mejorar la comprensión y el manejo de la euritrematosis en el ganado. Los hallazgos brindan información valiosa sobre el impacto de la enfermedad y sugieren estrategias para controlar sus efectos en la salud y la productividad del ganado.
