Isolation and identification of Avibacterium paragallinarum, the causal agent of infectious coryza (IC) from layer chickens in Bangladesh

This study was carried out for the isolation and identification of Avibacterium paragallinarum, the etiological agent of infectious coryza (IC). Pathological changes were also investigated that occurred in organs in layer chickens obtained from some selected areas of Bangladesh. A nasal swabs (n=30) from dead chickens and four swabs from live chickens were collected aseptically. The organisms f...

Antibiotic Sensitivity Pattern of Avibacterium Paragallinarum from Infectious Coryza in Andhra Pradesh

Infectious coryza is a respiratory disease of chicken primarily affecting upper respiratory tracts. Six outbreaks of infectious coryza were investigated from Andhra Pradesh. Three of them were in commercial chicken, two from native Aseel chicken and one from emu. Out of total 74 infra orbital sinus swabs tested, 27 (36.4%) gave isolates of Avibacterium paragallinarum. All the 27 isolates obtain...

Retrospective Detection of Avibacterium Paragallinarum Serovar B in Egg Yolk Materials by PCR

Avibacterium paragallinarum is Gram-negative bacteria that cause infectious coryza (IC), an acute respiratory disease of chickens. Despite vaccination of Layer and breeder farms of Iran against IC, they are still experiencing the disease clinically and there is no knowledge of serotypes prevalence of this bacterium in this country. This study designed to determine serovar identity by molecular ...
