It is expected of a Veterinary Parasitologist to possess extensive knowledge in parasitology, even to the point of accurately speciating a parasite. Diagnostics and interpretations about parasites that impact humans, wildlife, and laboratory animals are frequently also crucial. Two crucial components of parasitology are the diagnosis of a parasitic illness and accurate parasite identification. The appropriate technique in the right situation yields the right outcome. For common parasite illnesses, both laboratory confirmatory testing and field-based diagnostics are now accessible. Nowadays, immunodiagnostic is utilized to identify a wide range of parasite illnesses. It is the primary technique for ante mortem identification of concealed parasitic illnesses brought on by tissue or larval parasites.Nowadays, a lot of research is done using molecular approaches as a specialized diagnostic method, in anthelmintic resistance detection, speciation, and genotypic characterization.
