Coxsackieviruses are divided into group A and group B viruses based on early observations of their pathogenicity in neonatal mice. [1] 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).
Coxsackie B infections usually do not cause serious disease, although for newborns in the first 1–2 weeks of life, Coxsackie B infections can easily be fatal. [2] The pancreas is a frequent target, which can cause pancreatitis. [2] Coxsackie B3 (CB3) infections are the most common enterovirus cause of myocarditis and sudden cardiac death. [8]
sCAR-Fc (Soluble Receptor Analogue) is an experimental prophylactic treatment against coxsackievirus B3 (CVB) infections. Coxsackievirus B3 can cause cardiac damage, eventually resulting in a weakened and enlarged heart that is termed dilated cardiomyopathy. [1]
Coxsackie A virus is a subgroup of enterovirus A, which are small, non-enveloped, positive-sense, single-stranded RNA viruses. Its protective, icosahedral capsid has an external portion that contains sixty copies of viral proteins (VP1,-2,-3) and an internal portion surrounding the RNA genome containing sixty copies of VP4 viral proteins.
Herpangina, also called mouth blisters, is a painful mouth infection caused by coxsackieviruses.Usually, herpangina is produced by one particular strain of coxsackie virus A (and the term "herpangina virus" refers to coxsackievirus A), [1] but it can also be caused by coxsackievirus B or echoviruses. [2]
Coxsackie B4 virus and type 1 diabetes [ edit ] One theory proposes that type 1 diabetes is a virus-triggered autoimmune response in which the immune system attacks virus-infected cells along with the beta cells in the pancreas , [ 8 ] [ 9 ] but to date there is no stringent evidence to support this hypothesis in humans.
Hand, foot and mouth disease is a childhood illness most commonly caused by infection by Coxsackie A virus or EV71. Encephalitis is rare manifestation of enterovirus infection; [49] when it occurs, the most frequent enterovirus found to be causing it is echovirus 9. Myocarditis is characterized by inflammation of the myocardium (cardiac muscle ...
Bornholm disease, also known as epidemic pleurodynia, [1] is a condition characterized by myositis of the abdomen or chest caused by the Coxsackie B virus or other viruses. [2] The myositis manifests as an intermittent stabbing pain in the musculature that is seen primarily in children and young adults.
