Bordetella bacterins may be ____ against pulmonary bordetellosis.
Protective
Ascarids and Lungworms are causes of ______ pneumonia.
Verminous
Ascarids - etiology
Ascaris suum
Ascardis migrate through the liver and ____.
Lungs
These organisms result in large synchronous migrations (e.g., moving bigs from clean to contaminted environement) can cause severe pneumonia and death. What organisms do this?
Ascarids
Etiology of lungworms in pigs
Metastrongylus elongatus
Lungworm M. elongatus requires _____ as intermediate host to complete its lifecycle.
Earthworm
The adult lungworm of M. elongatus reside in the ______.
Terminal bronchioles
Etiology of Atrophic Rhinitis
Bordetella bronchiseptica
toxigenic Pasteurella multocida
Majority of Pasteurella multocida in the lungs do not hae the potential to produce atrophic rhinitis. What makes it able to cause disease?
There are certain types that produce toxins (acapsular type D specifically) that can result in retarding atrophic rhinitis.
Infection of Bordetella bronchiseptica and toxigenic Pasteurella multocida will always result in clinical problems. True or False.
False - infection does not always result in clinical problems. Environmental interactions and concurrent disease interactions play an improtant role in establishing infection.
