Samples of formalin fixed gastrointestinal organs of three month ostrich chicks were submitted to the department of Pathology, Razi Vaccine and Serum Research Institute. Histologically hepatitis and pancreatitis with large eosinophilic intra nuclear inclusion bodies were prominent in hepatic and pancreatic cells. These inclusions were suspected as adenovirus inclusion body hepatitis (IBH) in ...
Avian infectious bronchitis is an acute and highly contagious disease that mainly causes respiratory symptoms in poultry. A number of serotypes and variants of the viral agent with poor cross-protection are the major problem to achieve desired immunity from vaccination. The S1 subunit of S glycoprotein (spike) is the major determinant of IBV so that a minor change in amino acid sequence of this...

Abstract Mycoplasma pulmonis and muris infections have been associated with several diseases in conventionally housed laboratory rat and mice colonies. In naturally infected of mycoplasma pulmonis in mice and rat colonies, the respiratory organ appears to be the favored site of colonization; so, it was not surprising to see that infection spread from the site of urogenital tract to the respirat...
