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...

Characterisation of isolates of Haemophilus paragallinarum from Indonesia.

OBJECTIVE To characterise 18 isolates of Haemophilus paragallinarum isolated from chickens in Indonesia. PROCEDURE The isolates were identified to species level by traditional phenotypic methods. Six of the isolates were also identified by a species-specific polymerase chain reaction. Fourteen of the isolates were examined for resistance to a panel of seven antimicrobial agents using a disc d...

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 ...

Proposal of a new serovar and altered nomenclature for Haemophilus paragallinarum in the Kume hemagglutinin scheme.

By using the Kume hemagglutinin serotyping scheme, 13 Australian isolates of Haemophilus paragallinarum were shown to constitute a new serovar within the presently termed serogroup II. Because of the likelihood that new serovars will continue to be established, we propose a rationalization of the nomenclature of the Kume scheme. Under this altered scheme, the three recognized serogroups I, II, ...
