Resumen
La identificación de nematodos de interés médico y veterinario en muestras de suelo o alimentos es una acción compleja, debido a la gran diversidad de nematodos en el medio. El objetivo del estudio fue realizar la caracterización morfológica y morfométrica de diferentes estadios larvarios de Strongyloides stercoralis, Strongyloides venezuelensis, anquilostomas, Angiostrongylus cantonensis y Angiostrongylus costaricensis, con el fin de orientar el diagnóstico diferencial con otras especies de nematodos ambientales. Para realizar el estudio se fijaron las larvas y se midieron varios parámetros corporales, para lo cual se realizó estadística descriptiva y estudio de similitud entre especies del mismo género. Los resultados de las larvas estándar fueron compatibles con los descritos para la especie, con variabilidad en algunos parámetros. S. stercoralis y S. venezuelensis mostraron similitud de 59% para L1 y 79% para L3, con mayor diferenciación para EA, GPC y LPG. En el pool de larvas de anquilostomiasis hubo una gran variación en los parámetros evaluados, especialmente en relación con el CTC. Las larvas de A. cantonensis y A. costaricensis mostraron 48% de similitud entre L1 y 76% para L3. Mediante análisis morfométrico y de similitud se verificó la posibilidad de mejorar el diagnóstico diferencial de nematodos de origen ambiental.
