Ancylostoma ceylanicum and Ancylostoma caninum were found in cats from Prachin Buri, Thailand, with infection rates of 92% and 23%, respectively. In this survey, 75% of cats were infected with A. ceylanicum alone, the rest had mixed infections of A. ceylanicum and A. caninum. The worm burden range in 26 cats for A. ceylanicum and A. caninum were 1 to 83 and 1 to 10, respectively.
