Clinical Virology and Parasitology

The detection, isolation, characterization, disease producing properties of viruses is called as Clinical Virology. The Clinical virology laboratory acts on detection, monitoring and diagnosis of viral illness in human as well as animals.

Parasitology (Host Pathogen interaction) deals with the relationship status of the parasite and the host cell. It involves bacteriology, virology, microbiology, zoology and mycology. The host-pathogen interaction is defined as how microbes or viruses sustain themselves within host organisms on a molecular, cellular, organismal or population level. This term is most commonly used to refer to disease-causing microorganisms although they may not cause illness in all hosts. Because of this, the definition has been expanded to how known pathogens survive within their host, whether they cause disease or not. On the molecular and cellular level, microbes can infect the host and divide rapidly, causing disease by being there and causing a homeostatic imbalance in the body, or by secreting toxins which cause symptoms to appear. Viruses can also infect the host with virulent DNA, which can affect normal cell processes (transcription, translation, etc.), protein folding, or evading the immune response.
