Coxsackieviruses are a few related enteroviruses that belong to the Picornaviridae family of nonenveloped, linear, positive-sense single-stranded RNA viruses, as well as its genus Enterovirus, which also includes poliovirus and echovirus. Enteroviruses are among the most common and important human pathogens, and ordinarily its members are transmitted by the fecal–oral route. Coxsackieviruses share many characteristics with poliovirus. With control of poliovirus infections in much of the world, more attention has been focused on understanding the nonpolio enteroviruses such as coxsackievirus.
The entry of coxsackievirus into cells, especially endothelial cells, is mediated by coxsackievirus and adenovirus receptor.
Coxsackieviruses are divided into group A and group B viruses based on early observations of their pathogenicity in neonatal mice. Group A coxsackieviruses were noted to cause a flaccid paralysis (which was caused by generalized myositis) while group B coxsackieviruses were noted to cause a spastic paralysis (due to focal muscle injury and degeneration of neuronal tissue). At least 23 serotypes (1–22, 24) of group A and six serotypes (1–6) of group B are recognized.
Group B coxsackieviruses tend to infect the heart, pleura, pancreas, and liver, causing pleurodynia, myocarditis, pericarditis, and hepatitis (inflammation of the liver not related to the hepatotropic viruses). Coxsackie B infection of the heart can lead to pericardial effusion.
The development of insulin-dependent diabetes has recently been associated with recent enteroviral infection, particularly coxsackievirus B pancreatitis. This relationship is currently being studied further.
There were 29 species of coxsackieviruses until 1999, when two of them were abolished and the rest merged into other species.
The coxsackieviruses were discovered in 1948–49 by Gilbert Dalldorf, a scientist working at the New York State Department of Health in Albany, New York.
Dalldorf, in collaboration with Grace Sickles, had been searching for a cure for poliomyelitis. Earlier work Dalldorf had done in monkeys suggested that fluid collected from a nonpolio virus preparation could protect against the crippling effects of polio. Using newborn mice as a vehicle, Dalldorf attempted to isolate such protective viruses from the feces of polio patients. In carrying out these experiments, he discovered viruses that often mimicked mild or nonparalytic polio. The virus family he discovered was eventually given the name Coxsackie, from Coxsackie, New York, a small town on the Hudson River where Dalldorf had obtained the first fecal specimens.
The coxsackieviruses subsequently were found to cause a variety of infections, including epidemic pleurodynia (Bornholm disease), and were subdivided into groups A and B based on their pathology in newborn mice. (Coxsackie A virus causes paralysis and death of the mice, with extensive skeletal muscle necrosis; Coxsackie B causes less severe infection in the mice, but with damage to more organ systems, such as heart, brain, liver, pancreas, and skeletal muscles.)
The use of suckling mice was not Dalldorf's idea but was brought to his attention in a paper written by Danish scientists Orskov and Andersen in 1947, who were using such mice to study a mouse virus. The discovery of the coxsackieviruses stimulated many virologists to use this system, and ultimately resulted in the isolation of a large number of so-called "enteric" viruses from the gastrointestinal tract that were unrelated to poliovirus, and some of which were oncogenic (cancer-causing).
The discovery of the coxsackieviruses yielded further evidence that viruses can sometimes interfere with each other's growth and replication within a host animal. Other researchers found this interference can be mediated by a substance produced by the host animal, a protein now known as interferon. Interferon has since become prominent in the treatment of a variety of cancers and infectious diseases.
In 2007, an outbreak of coxsackievirus occurred in eastern China. It has been reported that 22 children died. More than 800 people were affected, with 200 children hospitalized.
