causes small red bumps/nodules on people
sporotrichiosis
caused by fungus: Blastomyces dermatitidis
Blastomycosis
environmental exposure to wounds , causes skin lesions and focal lymphadenopathy
blastomycosis
humans are often asymptomatic but can cause meningitis and encephalitis if they do get sick. carried by rodents

prevention for Cryptosporidiosis in calves
disinfection w/ effective disinfectants
Ensuring passive transfer of immunity - feeding colostrum

- Typically, disease of sheep and goats
- Affects mucocutaneous junction of the mouth in lambs
and goat kids
Orf - Contagious ectherma
what disease causes these signs in cattle
* Abortions
* Blood-tinged urine
* Blood in milk
* Infertility and early embryonic deaths
Leptosprosis
how can humans get lepto
- Contact with urine (or other body fluids, except saliva) from infected
animals. - Contact with water, soil, or food contaminated with the urine of
infected animals
Naturally transmitted among cats by fleas (flea POOP)
- if no fleas, no transmission
