Salmonella enteritidis infection in two species of Psittaciformes.
In 1990, Salmonella enteritidis phage type 4 was recovered from 2 young (<20-week-old) lilac-crowned Amazon parrots (Amazona finschi Schlater), one in Tennessee and one in Kansas. The parrot from Tennessee was treated for a plugged naris and anorexia before the S. enteritidis infection was discovered. The parrot from Kansas exhibited signs of septicaemia and died within 24 h of examination. An apparently healthy green-cheeked conure (Pyrrhura molinae) on the same premises as the parrot in Tennessee was positive for S. enteritidis phage type 4 on a cloacal swab. These are thought to be the first reported cases of avian infection with this phage type of S. enteritidis in the USA. As several infectious agents were present simultaneously in the parrots, the role of S. enteritidis phage type 4 in the clinical presentation could not be determined.
