The result showed that three isolates were serovar B. The mis-matching of challenge serovar with vaccine is the most likely explanation for these cases of paragallinaeum failure.

There is usually a rapid onset and morbidity is high in the flock, decreased feed and water consumption, retarded growth in young stock and reduced egg production in laying flocks.

Another more popular method is to treat the affected flock and keep it isolated until new stock has been raised in isolation as replacements. American Avibacterikm Association; Complicated infectious coryza outbreaks in Argentina.
