The response of hamsters to Ancylostoma ceylanicum was studied between days 13 and 200 after infection. The infected hamsters showed signs of anaemia, particularly between the 13th and 60th days. A significant loss in body-weight in the infected animals was also observed during this period. Serological studies with agar gel-diffusion, counterimmunoclectrophoresis and indirect hacmagglutination tests revealed positive reac tions between the 20th and 60th days followed by a negative response in the latent period between the 60th and 200th days of infection, counterimmunoclectrophoresis test remained positive for a period of 150 days in this experimental model.
