Abstract

Streptococcus suis infections in birds.

Abstract

Four cases of S. suis infection were diagnosed in psittacine birds (budgerigars, Forpus conspicillatus, Agapornis swinderiana, A. roseicollis) and 4 others in zebrafinches (Taeniopygia guttata costanatis), bull finches (Pyrrhula pyrrhula), canaries (Serinus canaria) and a duck. The main clinical and pathological manifestation was septicaemia with multiple sudden deaths in nestlings, young and adults. Other cases were solitary, with evidence for secondary involvement of S. suis. Four serotypable strains all belonged to serotype 9.
