excerpt from that abstract
The development of autoimmunity in certain instances is related to infectious agents. In this report, cytotoxic monoclonal antibodies (mAbs) that recognize epitopes on both enteroviruses and the bacterium Streptococcus pyogenes are described. Murine anti-streptococcal mAbs that were crossreactive with streptococcal M protein, human cardiac myosin, and other alpha-helical coiled-coil molecules were found to neutralize coxsackieviruses B3 and B4 or poliovirus type 1.
In most cases, coxsackieviruses cause mild flu-like symptoms and go away without treatment. But in some cases, they can lead to more serious infections.
Signs and Symptoms
Coxsackievirus can produce a wide variety of symptoms. About half of all kids infected with coxsackievirus have no symptoms. Others suddenly develop high fever, headache, and muscle aches, and some also develop a sore throat, abdominal discomfort, or nausea. A child with a coxsackievirus infection may simply feel hot but have no other symptoms. In most kids, the fever lasts about 3 days, then disappears.
Coxsackieviruses can also cause several different symptoms that affect different body parts, including:
Hand, foot, and mouth disease, a type of coxsackievirus syndrome, causes painful red blisters in the throat and on the tongue, gums, hard palate, inside of the cheeks, and the palms of hands and soles of the feet.
Herpangina, an infection of the throat which causes red-ringed blisters and ulcers on the tonsils and soft palate, the fleshy back portion of the roof of the mouth.
Hemorrhagic conjunctivitis, an infection that affects the whites of the eyes. Hemorrhagic conjunctivitis usually begins as eye pain, followed quickly by red, watery eyes with swelling, light sensitivity, and blurred vision.
