Abstract
Diseases of the respiratory tract are a significant
component of the overall disease incidence in
poultry. In many cases, respiratory disease observed
in a flock may be a component of a multi-systemic
disease or it may be the predominant disease with
lesser involvement of other organ systems. In some
cases, such as infectious coryza the
disease may be limited to the respiratory system, at
least initially. Various pathogens may initiate
respiratory disease in poultry, including a variety
of viruses, bacteria, and fungi. Environmental
factors may augment these pathogens to produce the
clinically observed signs and lesions. During
present study, an attempt was made to isolate H. paragallinarum from
the nasal swabs, eye swabs (from live birds) and caseous infra
orbital sinus and tracheal exudates swabs from dead
birds from commercial poultry farms Anand, Kheda and Mahuaregion
of Saurashtra area
of Gujrat state.
During the present study 6 H. paragallinarum isolates
were obtained from 109 samples suspected of
Infectious coryza infection.
