RESUMEN
ABSTRACT: Infections caused due to zoonotic hookworms are rare and are often under reported. Here we report a case of diarrheal disease caused by Ancylostoma ceylanicum, an important emerging zoonotic hookworm. There is limited knowledge about the epidemiology and disease burden of A. ceylanicum infections in Kerala. A 50-year-old male patient presented with complaints of loose stools for past five weeks. The laboratory investigations revealed a high total WBC count and eosinophil count. Diagnostic colonoscopy showed numerous worms which were identified as A. ceylanicum. Timely diagnosis aided in successful treatment of the patient. Improvement in diagnostic tools and awareness enable accurate and early detection of this neglected but emerging pathogen.
