Worldwide spread, especially in Asia, group Digenea is most diverse group of trematoda among others groups, capable to infest most of classes of vertebrates with support of invertebrate group (intermediate host). Digenean flukes can rigorously infect domestic ruminants as well as human, and become responsible for amphistomiasis disease. Paramphistomum cervi is digenean parasitic worm belonging to the class Trematoda, it is a tiny worm mostly parasitising domestic ruminants; buffalo, cow, sheep & goat and it cause severe diseases called paramphistomiasis.

Trematode includes worms which are endo-parasites having different shape, size, number, size of suckers, cuticle, oral organ, oesophagus, intestinal caeca, excretory vesicle, genital bulb, male and female reproductive organs.SEM photomicrograph revealed that the body of mature Paramphistomum cervi in conical shape and the anterior end narrow and the posterior being broad, and pink in colour. The tegumental surface is highly ridged with transverse folds discontinuous with grooves and is spineless, which is uncharacteristic of trematodes. The genital pore is situated at the anterior third of the body. There are two types of bulbous shaped sensory papillae on the surface, situated at the base with nipple-like tips.
