Paramyxoviridae - Protein Virus

Meaning of Paramyxoviridae: A family of viruses with special affinity for mucus proteins. Some properties are similar to orthomyxoviridae, but differ in morphology, nucleic acid composition and replication. The measles, respiratory syncytial and Newcastle disease virus in the undergraduate can infect humans and dogs at the same time, which is of great importance in the fields of medicine, veterinary medicine and military.

The Paramyxoviridae family in veterinary medicine includes Newcastle disease virus, Pev ruminant virus, and canine distemper virus.

Paramyxoviridae

Diameter: 150 nm

Paramyxoviridae Particulars

Polymorphic, slightly larger than orthomyxovirus, 150 nanometers or larger in diameter, with an envelope, and the surface of the envelope has ridge-like protrusions composed of glycoproteins.

The virus particle contains a spiral-symmetric core-shell, and the nucleic acid is a continuous ssRNA (single-stranded RNA) long molecule with a molecular weight (5-7) × 106.

RNA is negative stranded. During replication, RNA polymerase contained in the virion is transcribed into positive stranded mRNA (messenger ribonucleic acid).

RNA and protein synthesis are performed in the cytoplasm and sprout through the cytoplasmic membrane.

Viral replication cannot be inhibited by actinomycin D. No genetic recombination was found.

Most undergraduate viruses have erythrocyte adsorption and agglutination activity, neuraminidase activity, hemolytic activity, and cell fusion activity.

Diagrammatic View of Paramyxoviridae under a Microscope

Viruses usually contain 5 to 7 proteins such as RNA polymerase, hemagglutinin, neuraminidase, cell fusion protein, core-shell structural protein, and membrane protein.

Undergraduate virus-infected cell culture often causes multinuclear giant cell disease.

The viruses that are pathogenic to humans include parainfluenza virus, measles virus, mumps virus and respiratory syncytial virus.

Microbiology FAQs. Course and Journal

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.

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. The "SushrutaSamhita," "Charak Samhita," and "Bela Samhita," along w

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
