RHABDOVIRUSES Meaning and
Definition
-
Rhabdoviruses are a family of small, bullet-shaped, single-stranded RNA viruses that infect animals and humans, causing a range of diseases. They belong to the order Mononegavirales and are characterized by their unique morphology and replication cycle.
Structurally, rhabdoviruses possess a long, helical nucleocapsid core surrounded by an envelope that contains viral glycoproteins. This envelope is responsible for the distinctive bullet shape observed under electron microscopy. The genome of rhabdoviruses consists of a single strand of negative-sense RNA, which means it cannot be directly translated by host cells and must first be transcribed into positive-sense RNA.
Rhabdoviruses are known to infect a variety of hosts, including vertebrates and invertebrates. In humans, they are responsible for causing diseases such as rabies, which affects the central nervous system and is often fatal. Other notable rhabdoviruses include vesicular stomatitis virus (VSV), which primarily affects livestock, and Chandipura virus, which causes febrile encephalitis in humans.
The replication cycle of rhabdoviruses involves attachment and fusion with host cells, release of viral genes into the cytoplasm, and subsequent replication and assembly of new viral particles. The infection often leads to a strong immune response in the host, characterized by the production of neutralizing antibodies.
Overall, rhabdoviruses are a diverse group of viruses that have significant impacts on both human and animal health. Understanding their biology and pathogenesis is crucial for the development of effective strategies for prevention, diagnosis, and treatment of the diseases they cause.

Etymology of RHABDOVIRUSES
The word "rhabdoviruses" is derived from two Greek words: "rhabdos" meaning "rod" or "stick" and "virus" meaning "toxin" or "poison".
The term "rhabdo-" refers to the shape of the viruses in the family Rhabdoviridae. These viruses are typically elongated and rod-shaped, resembling a small stick or bullet. The use of "rhabdo-" to describe the shape of these viruses is a reference to the Greek word "rhabdos".
The term "virus" is a Latin word that originally meant "poison" or "toxin". It was later adopted in the field of microbiology to describe infectious agents that are smaller than bacteria and cannot replicate independently outside a living host cell.
