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

Can Dolphins Live in Fresh Water?

Is it Possible for Dolphins to Live in Fresh Water? We are very familiar with dolphins and fin-less porpoises, but dolphins and fin-less porpoises are both in the same family.  Why is there a difference between finless porpoise and porpoise?  Can dolphins follow the estuary and live in the big rivers?   Let me start with the answer: a small part can, the vast majority cannot. The reason is simply three sentences: can’t swim, eat, and live.   In detail, it may be longer and boring. You must be mentally prepared.   At present, whether it is fossil evidence or molecular biology research, it is still believed that cetaceans have a single origin, that is, the current whales and dolphins evolved from the same ancestor.  Of course, various whales and dolphins have embarked on their own different evolutionary paths. To this day, more than 80 kinds of whales and dolphins with completely different body shapes, habits and distribution areas have been evolved.  From the physical stru

Ayurveda Ayurvedic Treatment Therapy Science

What is Ayurveda? Ayurvedic Science and Treatment in India: Ayurveda is a form of healing and the science of long life. It is a traditional Indian therapeutic method that is well-known throughout the world. The Atharva Veda of the Vedas is its source. The Vedas is a vast body of knowledge that was directly transmitted from God to revered saints. The Vedas are also said to be God's own manifestation. The tie between Ayurveda and God is eternal since this knowledge is disclosed each time it is generated. The written history of ayurveda dates back more than 5,000 years. Before the written records, it had been around for thousands of years. Its herbal system is still used today, making it the oldest complete healthcare system in the world. Ayurvedic medicine is what is meant by this. According to legend, Maharshi Sushruta learned the fundamental principles of Ayurveda from Brahma.
