### agent | virus:

Adenovirus
* Most adenoviruses cause colds, diarrhea or pinkeye
* Most adenoviruses cause fatal diseases
  - respiratory diseases
  - illnesses
  - infection
  - intestinal infection
  - serious illnesses
  - grow easily in cell culture, and give rise to large intranuclear inclusions
* Some adenoviruses are present in the bowels and stools.
* Some adenoviruses infect animals
  - other animals
  - produce proteins
* also cause acute diarrhea in young children, characterized by fever and watery stools
  - pharyngoconjunctival fever in children
  - diarrhea, either alone, or in combination with respiratory disease
  - lower respiratory tract disease such as bronchitis and pneumonia
* are DNA-containing viruses typical of the common cold.
* are a common cause of gastroenteritis
  - sore throats and serious lung infections in humans
* are a family of DNA viruses that can infect both dividing and non-dividing cells
  - viruses that can infect people of all ages
  - major vector used for gene therapy
  - animal viruses
  - common causes of spring colds
  - double-stranded DNA viruses
  - human viruses that causes respiratory diseases including the common cold
  - infectious human viruses, which often cause mild respiratory illness
  - non-enveloped icosahedral particles
  - often the cause of the common cold
  - viruses that usually infect the tissue lining of the respiratory tract
* can also cause viral meningitis and other neurologic infections
  - or encephalitis
  - kill tumor cells specifically
  - cause tumours in animals
* can infect a broad range of human cells
  - both the intestine and the upper respiratory tract
  - man via the conjunctiva or the nasal mucosa
  - the mild, upper respiratory infection of a cold
  - upper respiratory, intestinal, and eye infections in humans
* encode viral proteins which bind to cellular tumor suppressor proteins.
* get themselves replicated by forcing an infected cell to divide.
* have a natural tropism for lungs in that they are associated with respiratory diseases.
* includes cell membranes
  - corpi
  - nuclei
  - plasma membranes
  - sections
  - vacuoles
* induce autophagy to promote virus replication and oncolysis.
* infect humans and many different animal species.
* is an animal virus
* produce cytopathic changes in their host cells
  - mild respiratory infections and conjunctivitis, affecting mostly children
* represent the largest nonenveloped viruses.
* take advantage of the impaired immunological response.
* usually infect the respiratory tract.

### agent | virus | adenovirus:

Parainfluenza virus
* continue to circulate.
* is an adenovirus

### agent | virus:

Animal virus
* Many animal viruses adsorb to the red blood cells of various animal species
  - contain an exterior lipid membrane with inserted proteins
  - have the ability to jump species barriers and kill humans
* Most animal viruses are enveloped
  - replicate and assembly in the cytoplasm
* Some animal viruses can also establish latent infections
  - cause transformation of host cells to the cancerous state
* are able to fuse with prokaryotic cells
* attach to the plasma membrane of an animal cell.
* can also change unpredictably when they jump the species barrier.
* enter host cells by a process called endocytosis.
* exhibit extreme variation in size and shape.
* share a number of common properties.

### agent | virus | animal virus:

Alphavirus
* are among the best-characterised enveloped viruses.
* can infect many different organisms.

Arenavirus
* appear to have granules when seen in electronmicrographs.
* are infectious agents carried by rodents that cause human illness similar to handovers.

Bunyavirus
* are responsible for a number of febrile diseases in humans and other vertebrates.
* replicate in the cytoplasm and obtain their envelope by budding from the golgi.
