oral cavity and upper GI tract (primarily ruminants)
___________________________ is the cause of contagious pleuropneumonia in swine.

Fusobacterium necrophorum
_______________________________ is an anaerobe commonly causing thrush in horses (infection of the frog).
Fusobacterium necrophorum
_______________________________ causes bloody dysentery in swine.
Brachyspira hyodysenteriae
_______________________________ is a common cause of infectious food poisoning associated with improper handling of poultry meat.
Campylobacter jejuni
_________________ is the most pathogenic of the Brucella species for humans.
Brucella melitensis
___________________ has the broadest host range of any of the Brucella species.
Brucella suis
_____________________ is the cause of the several manifestations of porcine proliferative enteropathy
Lawsonia intracellularis
_____________________ and _____________________ are the two most common sources of Francisella tularensis for humans.
ticks and other hematophagous arthropods and _cottontail rabbits
_____________________ is a major cause of death in individuals that develop fulminating infections with Neisseria meningitidis and N. gonorrhoeae
Septic shock (DIC, endotoxemia
_______________________________ is the cause of cholera in humans
Vibrio cholerae
_______________________________ was commonly involved in fistulous withers in horses.
Brucella abortus
Why do we not commonly see infections with Brucella abortus the above organism in fistulous withers anymore?
Brucella abortus has been all but eradicated from the cattle population in the U.S. and as a result, the organism is not available for causing infections in horses.
What is the role of Bordetella bronchiseptica in atrophic rhinitis in swine?
B. bronchiseptica colonizes the upper respiratory tract mucosa and, using its dermonecrotic toxin, is able to initiate minor damage to the mucosa of the nasal turbinates. This relatively minor damage facilitates the colonization of the nasal turbinates with toxigenic Pasteurella multocida which secretes its toxin and causes further turbinate damage.
Describe the clinical presentation of infectious canine tracheobronchitis:
Chronic, dry, nonproductive cough, occasionally with vomiting. The coughing begins acutely within a few days of contact with other dogs and is due to damage to the tracheal ciliated epithelium. The cough may last 4 to 6 weeks.
