Herpes Simplex Virus 1 and 2
2011-01-20 19:35:34

Herpes simplex virus 1 and 2 (HSV-1 and HSV-2), are two members of the virus family Herpesviridae that infect humans. They are both ubiquitous and contagious and can spread when an infected person is producing and shedding the virus. Symptoms include watery blisters in the skin, mouth, lips, or genitals. Lesions usually heal with a scab characteristic of herpetic disease. HSV-1 and -2 remain...

Baculoviruses
2011-01-12 15:55:50

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 described. Moth larval is the most common hosts but sawflies, mosquitoes, and shrimp are also known hosts. The viruses are not known to replicate in...

Coccolithovirus

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 during the summer of 2005, and was found to be a "giant-virus" having 472 protein-coding genes. It is the largest known marine virus by genome.

Human Parainfluenza Viruses
2011-01-05 16:00:36

Human parainfluenza viruses, belonging to the paramyxovirus family, are a group of four distinct serotypes of enveloped single-stranded RNA viruses. They are the second most common cause of lower respiratory tract infection in younger children. Many times the host has repeat infections throughout life with symptoms that may include upper respiratory tract illness or more commonly, a cold...

Canine coronavirus
2011-01-05 13:57:34

Canine coronavirus, of the Coronaviridae family, is a virus that causes a highly contagious intestinal disease in dogs. It was discovered in 1971 in Germany during an outbreak in sentry dogs. It replicates in the villi of the small intestine. Intestinal disease can be related to virus-induced apoptosis of cells. Originally the virus was thought to be very severe but is now considered to be...

Bovine Papillomavirus
2011-01-05 13:49:44

Bovine papillomavirus (BPV), of the Papillomaviridae family, is a group of DNA viruses common in cattle. The virus can cause warts of the skin and alimentary tract and in rare cases cancer. It is also though that equine sarcoid, a skin tumor, is brought on in horses and donkeys by BPV. BPV is a good model for the study of the papillomavirus molecular biology. Like others in their family...

Bluetongue Disease
2011-01-05 13:39:49

Bluetongue disease is a viral disease that is non-contagious, non-zoonotic, and insect-borne. It is mainly found in sheep and less commonly in cattle, goats, buffalo, deer, dromedaries, and antelope. It is not transmissible to humans. The virus is pathogenic, part of the genus Orbivirus, and is a member of the Reoviridae family. With 24 serotypes the virus can cause serious disease in...

African Swine Fever Virus
2011-01-05 13:01:59

The African Swine Fever virus, ASFV, is a double-stranded DNA virus that replicates in the cytoplasm of infected cells. It can affect most pigs, wild and domesticated, as well as soft ticks. It is the only virus with a DNA genome that is transmitted by arthropods. The virus causes a lethal hemorrhagic disease in domestic pigs which sometimes leads to death in as little as a week. In every...
