What are virological techniques?

A few of the most commonly used methods include: • Virus neutralization (VN) • Hemagglutination inhibition (HI) • Enzyme linked immunosorbent assay (ELISA) • Indirect fluorescent antibody (IFA) • Complement fixation (CF) • Agar-gel immunodiffusion (AGID) • Agar-gel precipitin (AGP) • Latex agglutination (LA).

What are the techniques followed for identification of viruses?

These techniques are chemical/physical measures of virus quantification and they include serologic assays, polymerase chain reaction (PCR), and hemagglutination assays (HA). Negative staining EM can also be used as a chemical/physical assay to detect and count virus particles.

What is pock assay?

Pock Assays Newly synthesized virus escaping from infected cells spreads mainly to adjacent cells, so that each infecting particle eventually gives rise to a localized lesion, known as pock. The morphology and color of the pock is often characteristic of a particular group of viruses or even a particular mutant.

What is the most common method of viral identification?

PCR is one of the most widely used laboratory methods for detection of viral nucleic acids. PCR analysis can also be used to determine viral RNA, by adding an initial step in which the RNA is converted into DNA; know as reverse transcriptase PCR (RT-PCR).

What tools do virologists use?

As most viruses are too small to be seen by a light microscope, sequencing is one of the main tools in virology to identify and study the virus.

What are the serological techniques used in detection and identification of virus?

Virus antigens are investigated by antigen detection assays. Serological diagnosis is based on either the demonstration of the presence of virus-specific IgM antibodies or a significant increase in the levels of specific IgG antibodies. Immunoassays are the most commonly used serological assays.

What are 3 methods to cultivate virus?

There are some methods of Cultivation of plant viruses such as plant tissue cultures, cultures of separated cells, or cultures of protoplasts, etc. viruses can be grown in whole plants.

Why is TCID50 important?

The 50% Tissue Culture Infectious Dose (TCID50) can be used to quantify and to assess the infectivity of a virus in cells. TCID50 assays are an important tool for the evaluation of anti-viral drugs, as they enable the investigation of the effect of drugs on the life cycle of a virus.

What instruments are used to study viruses?

Electron microscopy (EM) has long been used in the discovery and description of viruses. Organisms smaller than bacteria have been known to exist since the late 19th century (11), but the first EM visualization of a virus came only after the electron microscope was developed.

Who is father of Virology?

Martinus Beijerinck
Martinus Beijerinck is often called the Father of Virology.
