Ross University School of Veterinary Medicine, through the One Health Center for Zoonoses and Tropical Veterinary Medicine, provided the funding for this doctoral thesis together with Universidad de Granada and Universitat de Valencia. ; Worldwide, most cases of trichuriasis remain undiagnosed, chronic infections remain undetected and an overall lack of understanding of potential zoonotic exposures prevails. Therefore, early diagnosis of trichuriasis and diagnostic methods that do not rely on inconsistent clinical signs or fecal analysis are crucial to detect infections following accidental ingestion and during prolonged prepatent period of the parasite. The difficulty of access to the parasitic material (feces and adult nematodes) and biological samples from the hosts, further threatens the development of alternative diagnostic methods. With our work, we show that the St. Kitts green monkey being naturally infected with T. trichiura, serves as a predictive disease modeling test system that facilitates preclinical evaluation having similar immunological responses as humans. ; A nivel mundial, la mayoría de casos de trichuriasis permanecen sin diagnosticar, las infecciones crónicas no son detectadas, y prevalece una falta general de comprensión en cuanto a su potencial zoonótico. Por lo tanto, el diagnóstico temprano de trichuriasis unido a métodos de diagnóstico que no se basen en signos clínicos inespecíficos o únicamente en análisis de heces son cruciales para detectar infecciones accidentales especialmente durante el prolongado periodo prepatente del parásito. La dificultad de acceso al material parasitario (heces y nematodos), y a muestras biológicas de los hospedadores, complica aún más el desarrollo de métodos de diagnóstico alternativos. Con nuestro trabajo, demostramos que el mono verde de St. Kitts, al estar naturalmente infectado con T. trichiura, facilita su uso como un modelo para la evaluación preclínica de la enfermedad al tener una respuesta inmunológica similar a la de los humanos. ; Tesis Univ. ...
