The baculoviruses, are a family of large rod-shaped viruses, divided into two genera: nucleopolyhedroviruses (NPV) and granuloviruses (GV). Baculoviruses have species-specific tropisms among the invertebrates with over 600 host species having been desc...

Hepadnaviruses can cause liver infections in humans and animals. The two recognized genera are Genus Orthohepadnavirus and Genus Avihepadnavirus. It has a small genome of partially double-stranded, partially single stranded circular DNA. It is a group ...

Henipavirus, a genus of the Paramyxoviridae family, contains two members: Hendravirus and Nipahvirus. Pteropid fruit bats are natural harborers of the henipaviruses. They are characterized by a large genome, a wide host range, and their zoonotic pathog...

Hantavirus is part of the Bunyaviridae family. This family is divided into 5 genera: Orthobunyavirus, Nairovirus, Phlebovirus, Tospovirus, and Hantavirus. Hantaviruses have genomes comprising three negative-sense, single-stranded RNA segments. Viruses ...

Cytomegalovirus, a herpes viral genus, is known in humans as HCMV. It is part of the Betaherpesvirinae subfamily. Other herpesviruses fall into the subfamilies of Alphaherpesvirinae or Gammaherpesvirinae. xHCMV infections are frequently associated wi...

The Cowpox virus causes a skin disease known as cowpox. It is related to the vaccinia virus and gained its name because it spread by dairymaids touching the udders of infected cows. It manifests as red blisters. It is similar to smallpox although much ...

Human rhinoviruses are the most common viral ineffective agents in humans and are the cause of the common cold. The infection proliferates between 33-35 °C causing most reproduction to occur in the nose. It is a species in the genus Enterovirus of t...

Peritonitis (FIP) affects cats and is lethal. Some believe it is the cause of Feline Infectious Peritonitis Virus (FIPV) which is a mutated form of Feline Enteric Coronavirus. The most common theory is that the normally benign FECV mutates into FIPV. T...

Flavivirus is a genus of the family Flaviviridae. This genus includes the West Nile Virus, Dengue Virus, Tick-borne Encephalitis virus, yellow fever virus, and quite a few others. Flaviviruses get their name from the yellow fever virus. Flavus means ye...

Filoviridae family of viruses belongs to the order of Mononegavirales. Filoviruses cause hemorrhagic fever often with fatal bleeding and coagulating abnormalities. The name comes from the Latin word filum, which alludes to the thread-like appearance of...

Feline viral rhinotracheitis (FVR), caused by feline herpesvirus 1, is an upper respiratory infection of cats. It can also be referred to as feline influenza or feline coryza. FVR causes one-half of respiratory disease in cats. Feline calicivirus is an...

Feline leukemia virus (FeLV), a retrovirus that infects cats, is transmitted between infected cats through saliva and nasal secretions. If the cat's immune system does not take care of the disease then it can be lethal due to it being a cancer of blood...

Feline calicivirus (FCV), in the Caliciviridae family, is one of two important viral causes of respiratory infection in cats. FCV can be isolated from around 50 percent of cats with upper respiratory infection. The various strains of FCV vary in vi...

Equine Infectious Anemia, also called swamp fever, transmitted by bloodsucking insects infects horses and is cause by a retrovirus. It is endemic in the Americas, parts of Europe, the Middle and Far East, Russia, and South Africa. It is a lentivirus, s...

Eastern equine encephalitis virus (EEE), also called sleeping sickness or Triple E, is a zoonotic alphavirus and arbovirus that exists in the Americas and the Caribbean. It was first seen in Massachusetts in 1831 when 75 horses died of encephalitic ill...

Cypoviruses or CPV, are a genus of viruses in the Reoviridae family. The virions structure is similar to other reoviruses with a genome composed of 10 segments of double-stranded RNA. The virions are embedded in a protein matrix in order to form struct...

Coronavirus, a species in the genera of animal virus, belongs to the subfamily Coronavirinae in the family Coronaviridae. They are enveloped viruses with single-stranded RNA genome and a helical symmetry. The genome size ranges from 16 to 31 kilobases....

Coccolithovirus, a giant double-stranded DNA virus, infects Emiliania huxleyi, a species of coccolithophore. The virus was first observed in 1999 by W.H. Wilson and his team at the Marine Biological Association. It was sequenced for the EhV-86 strain d...

The Sin Nombre virus (SNV) is the agent of hantavirus cardiopulmonary syndrome (HCPS). Originally called "Four Corners Virus" or "Navajo Flu", but was changed after local residents objected. Near the home of one of the initial patients, the virus w...

The Epstein-Barr virus (EBV), or human herpesvirus 4, is part of the herpes family and causes cancer. It is one of the most common viruses in humans and is correlated to the pathogenesis of multiple autoimmune diseases including rheumatoid arthritis, s...
