The plaque reduction neutralization test is used to quantify the titer of neutralizing antibody for a virus. [1] [2] The serum sample or solution of antibody to be tested is diluted and mixed with a viral suspension. This is incubated to allow the antibody to react with the virus. This is poured over a confluent monolayer of host cells.

Plaques from a virus isolated from a compost heap near UCLA. The bacterium is M. smegmatis. A viral plaque is a visible structure formed after introducing a viral sample to a cell culture grown on some nutrient medium. The virus will replicate and spread, generating regions of cell destruction known as plaques.
There are two main forms of plague infection: bubonic, which is caused by a flea bite or blood contact with another infected animal or material and is characterized by swollen lymph nodes or ...

Colorado health officials have confirmed a human case of the plague, the rare bacterial infection infamously known for killing tens of millions in 14th century Europe. Today, it's easily treated ...
One means of determining whether the cells are successfully replicating the virus is to check for a change in cell morphology or for the presence of cell death using a microscope. Other viruses may require alternative methods for growth such as the inoculation of embryonated chicken eggs (e.g. avian influenza viruses [ 4 ] ) or the intracranial ...
Pneumonic plague can be caused in two ways: primary, which results from the inhalation of aerosolized plague bacteria, or secondary, when septicemic plague spreads into lung tissue from the bloodstream. Pneumonic plague is not exclusively vector-borne like bubonic plague; instead, it can be spread from person to person. There have been cases of ...
