Megabacteria and proventricular/ventricular disease (PVD) in budgerigars (Melopsittacus undulatus) and European goldfinches (Carduelis carduelis) in Australia

2023
Megabacteria are large, Gram-positive, periodic acid Schiff (PAS)-positive, rod-shaped, non spore-forming, single-celled organisms. Neither their pathogenicity nor taxonomy has yet been determined. The organisms are frequently found in large numbers in the proventriculus of birds and have been associated with proventricular/ventricular disease (PVD), a

During the second half of the year 2000, we have diagnosed a megabacterial-associated proventriculitis in 13 laying hens and 4 cocks from 14 different flocks and one turkey. All birds were submitted for necropsy because of progressive runting, increased mortality and poor laying performance in the herds.

Tierarztliche Praxis. Ausgabe G, Grosstiere/Nutztiere, 1998
Three cases of a disease similar to going light syndrome in budgerigars in a flock of young laying hens in Turkey are reported. In all cases megabacteria in association with E. coli could be isolated. The causing agent appeared to be large, rod-shaped, gram-positive or gram-labil, and catalase test positive bacteria with cytochromoxydase activity ...
