To the Editor: Streptococcus suis is an emerging zoonosis in humans and a common pathogen in Australian pigs.1 However, only two cases of human infection have previously been reported in Australia.2,3 We recently treated two Australian piggery workers, from the same town in New South Wales, for S. suis endocarditis.
