Systemic
mycoses in farm animals |
Systemic mycoses are much less commonly diagnosed in cattle,
horses, pigs and other livestock than in dogs and cats. However,
the following infections have been reported:
- nasal granulomas in horses due to infection with Coccidioides,
Histoplasma and Cryptococcus
- pneumonia in cattle due to infection with Coccidioides
and Histoplasma (very rare)
- In horses, primary cutaneous blastomycosis occurs, and Blastomyces-induced
fever, pyogranulomatous pneumonia, pleuritis and peritonitis
with abscessation has been reported in a horse in Ohio.
- Cryptococcus mastitis in cattle
- Cryptococcus meningoencephalitis and pneumonia in
elk
- Histoplasma farciminosum infection in horses (rarely
cattle) (a foregin animal disease as regards the U.S.)
- Infection via abrasions, inhalation and coitus leads to subcutaneous
granulomas and cording of lymphatics (rarely pulmonary or other
systemic forms of disease).
- DDx = glanders (Burkholderia [formerly Pseudomonas]mallei
infection) (also a foregin animal disease as regards the U.S.)
