Experimental infection of Gnathostoma spinigerum larvae in prawns and tadpoles

Naturally captured Lanchester's freshwater prawns (Macrobrachium lanchesteri) and farm-bred Rana regulosa tadpoles were assessed for their capability of being the first or second intermediate hosts of Gnathostoma spinigerum. Seventy specimens from each animal group were randomized into a contro...

Another 120 specimens of each animal were used in two treatment groups; 60 being exposed to the first-stage larvae, G. spinigerum, and 60 exposed to cyclops containing the third-stage larvae for 7 days. No larvae of G. spinigerum were found in the prawns of both treatment groups that resembled tadpoles exposed to the first-stage larvae.
