Acute necrotising pneumonitis associated with Suttonella ornithocola infection in tits (Paridae).
Suttonella ornithocola, first isolated from the lungs of British tit species in 1996, was found to be a novel bacterium belonging to the family Cardiobacteriaceae. Comprehensive surveillance of garden bird mortality across Great Britain between April 2005 and April 2009 involved post mortem and microbiological examination of 82 tits (Paridae; multiple species) and six long-tailed tits (Aegithalidae; Aegithalos caudatus). S. ornithocola was isolated from six birds submitted from six incidents of morbidity and mortality involving Paridae and Aegithalidae species with a wide geographical distribution. The mortality incidents occurred sporadically at low incidence throughout the study period, which suggested that the infection is endemic in native bird populations, with a seasonal peak during early spring. Histopathological examination showed multiple foci of acute pulmonary necrosis associated with gram-negative cocco-bacillary bacteria. These findings supported the hypothesis that S. ornithocola is a primary pathogen of tits in Great Britain.
