Per incidence up to twenty dead tits and a loss of tits around feeder stations respectively were detected. In three coal tits (Periparus ater), one blue tit (Cyanistes caeruleus) and one great tit (Parus major) acute necrotic pneumonia with intralesional rod-shaped bacteria and reddish-black contents of intestine were detected. In two birds inflammatory infiltrates were detected in the intestinal mucosa histologically. Bacteriology showed β-hemolytic colonies in lung, liver and intestine on Columbia sheep blood agar. Routine biochemical testing and MALDI-TOF lead to no results. 16S rDNA sequence analysis revealed Suttonella (S.) ornithocola. Since we isolated S. ornithocola from the intestine and detected inflammatory infiltration in the intestinal mucosa it might also be associated with enteritis. This case report is the first description of S. ornithocola-associated mortality in tits in Germany. Suttonella ornithocola is a recently discovered bacterium belonging to the family Cardiobacteriaceae. In 1996 S. ornithocola was reported to cause mortality in tits in Great Britain. In these tits necrotic pneumonia was detected. The cases described in Great Britain regarding clinical signs, post mortem and histopathological findings as well as bacteriological examination show close similarities to those described in this case report. Thus, S. ornithocola may be a cause of recent tit mortality in North Rhine Westphalia, Germany, and should be included in the list of potentially fatal pathogens of tits in Continental Europe. a0005-9366
