What causes pink eye in cows?
Moraxella bovis
Infectious bovine keratoconjunctivitis (pink eye)
Infectious ovine keratoconjunctivitis is caused by what pathogens?
Mycoplasma conjunctivae
Chlamydia pecorum
What two pathogens can cause otitis in calves?
Mycoplasma bovis and Histophilus somni
Why are dogs more prone to get ear infections than cats?
Long horizontal ear canal to capture bacteria and debris
T/F: Otitis externa is a primary infection
FALSE
Almost always secondary infections, so you need to look for and treat primary cause to prevent recurrent infections
What is the MOST common bacterial organism involved in canine otitis externa? What is the most common yeast involved?
Pseudomonas aeruginosa
Malassezia pachydermatis
What two bacterial pathogens cause conjunctivitis in cats?
Mycoplasma felis Chlamydia felis (feline pneumonitis)
What systemic bacterial infections are often associated with conjuctival effusion?
Rickettsia
Anaplasma
Ehrilickia Brucellosis
Leptospirosis
What systemic mycoses are associated with conjuctivitis?
Blastomycosis Cryptomycosis Histoplasmosis Coccidiomycosis Protothecosis
Equine recurrent uveitis is associated with what bacterial infection?
Leptosporosis
What is the main clinical sign you will see in a horse with guttural pouch mycosis?
Epistaxis – blood draining out the nose
Guttural pouch mycoses may occur as a complication of:
- Strangles
- Pigeon fever
- Glanders
- Pseudoglanders
Strangles (Streptococcus equi subsp equi)
mycoses is often caused by Aspergillus sp
What pathogens are often involved in keratitis and associated complications in horses?
Aspergillus sp
Fusarium sp
Candida sp (these 3 are fungi)
Pseudomonas, Staph, and strep
Where does the lower respiratory tract start?
Starts at the intrathoracic trachea – everything past that point
T/F: Upper respiratory tract dz in dogs is most commonly due to viral infections
TRUE
What is the most common bacterial organism to cause URI in dogs?
Bordetella bronchiseptia = Kennel cough
Fungal infections causing URI = cryptococcosis, aspergillosis
What is a telltale sign a dog has a URI caused by a aspirgillosis?
de-pigmentation of the nose
What fungus-like organism causes nasal polyps in canines?
Rhinosporidium seeberi
*more common in southeast US
What pathogens are responsible for pneumonia and pyothorax in dogs?
Nocardia
Antinomyces
When is fecal testing indicated for a respiratory infection?
neverforgetparasit
If you suspect lung worms or other parasites that migrate through the lungs
What are three fungal infections that will present at primary lung disease with the addition of skin lesions?
Blastomyces dermatitidis Histoplasma capsulatum (causes HGE in dogs) Coccidioides immitis (osteomyelitis)
What geographic location will you find coccidioides immitis?
South west US - San Joaquin valley
