Twenty-eight pigs died in an outbreak of streptococcal meningitis in an East Anglian herd. Most were 10–14 weeks old. The outbreak lasted from January to April and was finally controlled by antibiotic therapy. A similar number of losses had occurred in the previous year though no diagnosis had then been made.

The causal agent appeared to be a haemolytic streptococcus belonging to group D and provisionally designated Streptococcus suis type 2. It is probably identical with de Moor's group R streptococcus which causes a similar disease in the Netherlands. It is serologically distinct from Streptococcus suis type 1 which causes meningitis in piglets. Type 2 infection in pigs appears to be widespread in England and Wales and to occur in animals up to the age of at least 14 weeks.

A comparison is drawn between Str. suis meningitis in pigs and group B streptococcal meningitis in human infants.
