(Field et al., 1954; de Moor, 1963;Elliott, 1966). Human infection occurs rarely and is usually in people whose work involves prolonged contact with live or slaughtered pigs (Zanen and Engel, 1975). Case reports of human disease comprising septicaemia and meningitis have appeared from Denmark (Perch et al., 1968; Koldkjaer and Nielsen, 1971), Holland (Zanen and Engel, 1975), and Great Britain (Hickling and Cormack, 1976).In the case reported here the patient had, in addition to a septicaemia and meningitis, a sensorineural deafness, labyrinthitis, and severe bilateral endophthalmitis. This is the first report of endophthalmitis secondary to Streptococcus suis type II (group R).
