Alpha Virus Types Category and Infections

Types and Category of Alpha virus

Definition of Alpha Virus: Alpha virus, a genus of the Toga virus family. Spherical viruses with a diameter of 50-70 nm.

Medical Name:    Alpha virus

English Name:     Alphavirus

The diameter is:    50-70nm

Molecular weight: 30000

Meaning of Alphavirus

The encapsulated icosahedral nucleocapsid is 30-40 nanometers in the envelope. The specific gravity is 1.18-1.25. There are two types of structural proteins (capsid protein: molecular weight 30,000; envelope protein: molecular weight 52,000). It can infect humans, often causing children with hemorrhagic fever syndrome, arthralgia, fever and other symptoms.

What types of Viruses are Affiliated to Alpha Virus?

  • Sin-dbis virus
  • Chikungunya virus
  • Eastern equine encephali-tis virus
  • Western equineencephalitis virus
  • Mayaru Virus (Mayarovirus)
  • Semliki forest virus (Semliki forest virus)
  • Venezuelan equine encephalitis virus (Venezuelan equine encephalitisvirus)

Coxsackie virus Coxsackie virus is a nucleovirus (Picornavirus). Virus particles are icosahedrons with a diameter of 27-28 nanometers. 
The particles contain RNA (impregnating nucleic acid) with a molecular weight of 2.0 X 106.

In 1948 by G. Dalldorf and G. M. Sickles was isolated from the feces of polio-like paralysis patients in Coxsackie, New York, USA. It shows strong pathogenicity to mole rats.

What are the categories of Alpha viruses?

According to pathological studies, it can be roughly divided into two categories, A and B. 

Alpha Viruses and Other All types of Viruses

There are 23 species in category A and 6 species in category B. It is an oral infection to people, causing aseptic meningitis, herpes angina, epidemic myalgia, hand-foot-mouth disease and so on. 

Type B can fully proliferate in simian kidneys, human amniotic membrane, HeLa cells, FL and other strains of cells, showing cell degeneration, but type A does not show obvious cell degeneration except for a part.
Like polio virus and ECHO virus, guanidine can inhibit proliferation. Interference can be found between Type B and poliovirus, both in vitro and in vivo.

Microbiology (Academic Subject and Medical Department) Meaning of Microbiology : Microbiology is one of the branches of biology. It is to study the morphological structure, growth and reproduction of various micro-organisms (bacteria, actinomycetes, fungi, viruses, Rickettsia, mycoplasma, chlamydia, spirochete protozoa and single-cell algae) at the molecular, cellular or population level. It is also a name of medical department that studies and applies the subject. It also studies physiological metabolism, genetic variation, ecological distribution and taxonomic evolution and other basic laws of life activities, and apply it to science in the fields of industrial fermentation, medical hygiene and bioengineering. Microbiology is a science that studies the laws of life activities and biological characteristics of various tiny organisms.   Discipline Name:     Microbiology Subject:     Biology Definition:     One of the branches of biology studying micro organisms

Herpes Virus Infections Biological Traits Immunity and Pathogenicity

Infections Biological Traits Pathogenicity of  Herpes Virus Herpes simplex virus (HSV) is a typical representative of herpes virus. It is named because herpes simplex occurs in the acute phase of infection.  It can cause a variety of human diseases, such as gingivostomatitis, keratoconjunctivitis, keratoconjunctivitis, encephalitis, and reproductive system infections and newborn infections. After infecting the host, a latent infection is often established in nerve cells. After activation, asymptomatic detoxification will occur. The chain of transmission will be maintained in the population and it will circulate repeatedly.
