Objective To investigate the popularity and distribution of Paragonismus westermani in Zengcheng City ,a northeast suburban city of Guangzhou .Methods Freshwater crabs were picked from creeks .Paragonismus metacercariac from infected crabs were used to artificially infect domestic dogs .Dogs diagnosed with positive Parago‐nismus metacercariac infecion were dissected ,and adult Paragonismus metacercariac were detected from lung sam‐ples .Results The natural infection rate of Paragonimus westermani in crabs was 58 .46% (38/65) .the number of metacercariae per infected crab and per gram of infected crab were 2 .12 and 0 .59 ,respectively .The infected crabs were identified as Nanhaipotamon pingyuanense .A total of 42 adult worms of Paragonimus westermani were found from two dogs with positive Paragonismus metacercariac infecion .Conclusion Zengcheng City could be a natural epi‐demic focus of Paragonimus westermani (Grade Ⅲ) .
