The autopsy method and classifying identification for helminth species based on their parasitic location, appearance, size, external and internal morphology were used. Out of a total of 160 snakes (80 Cylindrophis ruffusand 80 Enhydris enhydris snakes) were examined, there were 150 snakes infected with helminths with an average rate of 93.75% (95% of Cylindrophis ruffus snakes and 92.50% of Enhydris enhydris snakes). Meanwhile, the Cylindroids ruffus snakes were infected with 3 helminth classes, of which the infection rate with Cestoda class (tapeworms) was highest (60.00%), followed by Trematoda class (flukes): 30.00% and Nematoda class (round worms): 22.50%. The Cylindrophis ruffus snakes were infected with 8 helminth species: 4 species of Trematoda class with the infection rates Proctoces sp. (27.50%), Haplometroides buccicola (7.50%), Singhiatrema vietnamenses (15.00%) and Travtrema stenocotyle (12.50%)
3 species of Cestoda class (tapeworms) with the infection rates Mesocestoides sp. (32.50%), Autralotaenia bunthangi (32.50%) and Spathebothriidea sp. (17.50%), and one species of class Nematoda (roundworms) was Ophidascaris durissus with the infection rate 22.50%. The Enhydris enhydris snakes were infected with 2 helminth classes, the infection rate with Trematoda class was 92.50%, and with Cestoda class (tapeworms) was 10%, the snakes infected with Nematoda was not found. There were 8 helminth species found on the Enhydris enhydris snakes, of which 5 helminth species belong to Trematoda class (fluke), with the infection rate Haplometroides buccicola (70.00%), Singhiatrema vietnamenses (57.50%), Travtrema stencotyle (37.50%), Platynosomum sp.(25.00%) and Proctoces sp. (10.00%) and 3 species of class Cestoda (tapeworms), with the infection rate Autralotaenia bunthangi (10.00%), Spathebothriidea sp. (5.00%) and Mesocestoides sp. (2.50%). Among the helminth species were found in two snake species, Platynosomum sp. and Mesocestoides sp. could be transmissible to human.
