Echovirus 9 (also known as E-9, E.C.H.O. 9, and formerly Coxsackie A23 or A23 virus) [1] is a serotype of echovirus. When first discovered, it was labelled as a coxsackie A virus, A23. It was later discovered that A23 was an echovirus antigenically identical to the already-known echovirus 9. [2] Echovirus 9 is the most common enterovirus type. [3]
Coxsackievirus shows a cardiac tropism partly due to the high expression of coxsackievirus and adenovirus receptors (CAR) in cardiomyocytes. [3] Coxsackievirus B genome is approximately 7.4 Kb and translated as a polycistronic polyprotein. Upon translation, the polyprotein is cleaved by two essential viral proteases, 2A and 3C. The viral ...
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]
Viral cardiomyopathy occurs when viral infections cause myocarditis with a resulting thickening of the myocardium and dilation of the ventricles. These viruses include Coxsackie B and adenovirus, echoviruses, influenza H1N1, Epstein–Barr virus, rubella (German measles virus), varicella (chickenpox virus), mumps, measles, parvoviruses, yellow fever, dengue fever, polio, rabies, and the ...
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.
Coxsackievirus and adenovirus receptor (CAR) is a protein that in humans is encoded by the CXADR gene. [ 5 ] [ 6 ] [ 7 ] The protein encoded by this gene is a type I membrane receptor for group B coxsackie viruses and subgroup C adenoviruses .
Coxsackievirus B4 is one of the six serotypes found in Group B and is a positive sense, single-stranded, non-enveloped RNA virus. Its genome is linear and is 7,293 nucleotides in length with both a 5’ and 3’ untranslated region and encodes its own 3’ poly-A tail.
