Q

Guinea pig, after partuition, begins to show signs of URI. Within a few days she dies. Necropsy shows finbrinopurulent pleuritis, pneumonia, pericarditis, endometritis….what are you thinking?

A

Strep pneumonia
it’s transmitted aerosol, direct or during birth the Repro tract gets infected.
There can be asymptomatic carriers so be careful!
high mortality and will have URI signs!
Treat with tetra, Chloramphenicol and TMS.
