Sucking pigs develop swollen joint in the legs from 3 weeks of age. What is the most likely cause of this lesion?



Correct answer

Streptococcus suis serotype 2 was isolated from this joint.

The cause of joint ill is bacterial infection of the piglet, pre-weaning. The majority of cases are caused by opportunist infection from the environment with, for example, E. coli, Staphylococci and Streptococci. There are specific infectious agents that can produce outbreaks of joint ill (and meningitis) like in this case.
