The laboratory of parasitology and mycology unites two specialties in one workplace. The first speciality, human parasitology, is concerned with infections affecting humans that are caused by organisms of animal origin – protozoa, worms and arthropods. The second speciality, medical mycology, is concerned with the diagnostics of infectious diseases that are caused by microscopic fungi (micromycetes). The laboratory carries out the diagnostics of all parasitic infections occurring in the Czech Republic, and of some tropical parasitoses affecting our citizens who have visited exotic countries. The laboratory of parasitology and mycology employs the methods of demonstration of antibodies to diagnose some diseases transmitted from animals to humans, mainly toxoplasmosis, toxocariasis, borreliosis, and leptospirosis, for which South Bohemia is one of the endemic regions. With the development of invasive treatments and growing successes of oncological therapy grows the importance of medical mycology. Infections caused by micromycetes threaten the lives of patients with reduced immunity. The laboratory of mycology performs the diagnostics of the causative agents of mucous membrane and organ mycoses caused by yeasts and filamentous mycomycetes. Other causing agents determined here are those causing superficial mycoses affecting the skin, nails and mucous membranes. The laboratory provides consultation services for the medical public as well as other expert public, is involved in lecture activities and postgraduate education.
