______________________________ is the cause of blackleg in ruminants
_______________________________is the cause of fowl coryza.
_______________________________ is the cause of Glasser's disease in swine.
What are the typical tissues or organ systems involved in Glasser=s disease?
Glasser=s is a polyserositis and any serosoal surface may be infected as well as the joints
_______________________________ is a cause of enteritis in young rodents and focal hepatic necrosis, jaundice and enterocolitis in older rodents.
_______________________________ is the cause of contagious equine metritis.
_______________________________ is the cause of whooping cough in humans.
_______________________________ is the cause of wooden tongue in cattle.
_______________________________ is the natural habitat of the organism that causes wooden tongue.
oral cavity and upper GI tract (primarily ruminants)
___________________________ is the cause of contagious pleuropneumonia in swine.
_______________________________ is an anaerobe commonly found in uterine infections in dairy cattle
_______________________________ is an anaerobe commonly causing thrush in horses (infection of the frog).
_______________________________ causes bloody dysentery in swine.
_______________________________ is a common cause of infectious food poisoning associated with improper handling of poultry meat.
_________________ is the most pathogenic of the Brucella species for humans.
___________________ has the broadest host range of any of the Brucella species.
_____________________ is the cause of the several manifestations of porcine proliferative enteropathy
_____________________ 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
_______________________________ was commonly involved in fistulous withers in horses.
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.
Briefly (30 words or less) discuss the pathogenesis of infectious bovine keratoconjunctivitis:
Initial damage to the corneal epithelium due to dust, excessive UV light, long stemmy grass or weeds, etc. Mycoplasma bovoculi colonizes the corneal lesions. Moraxella bovis subsequently colonizes the corneal lesions and produces a variety of proteases, a hemolysin, etc. that can heavily damage the epithelium. Neutrophils that migrate to the area are lysed and release their hydrolytic enzymes thus augmenting the damage. (key has more than 30 words to cover all possible answers

abortion ; hepatitis
_______________________ is a disease primarily of sheep caused by Clostridium novyi Type B.
