Adenoviruses

A group of viruses that attack cattle, dogs, horses, mice and birds in addition to humans. 41 human serotypes are known.

The group is divided into two genera:
 * mastadenovirus,
 * aviadenovirus.

Virion
The virion is 70-90 nm large, resistant to ether, sensitive to chlorine and its derivatives.

Diseases

 * 1) Acute diseases of the respiratory tract – pharyngitis, fever, bronchitis, bronchopneumonia or pneumonia.
 * 2) Conjunctivitis – mostly in summer (possible water transfer).
 * 3) Diseases of the digestive system – mesenteric adenitis or diarrhea.

Pathogenesis

 * Gate of entry: mucous membranes of the respiratory and digestive tract, conjunctiva.

Diagnostics

 * Isolation – from the conjunctival sac, nasopharyngeal secretion, from urine on cell cultures;
 * ELISA.

Epidemiology
Virus spreads as droplet infection - secretions from infected mucous membranes. Less often through urine and faeces.
