Detection of aves polyomavirus 1 (APyV) and beak and feather disease virus (BFDV) in exotic and native Brazilian Psittaciformes.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
There are several viral diseases in captive birds. Aves polyomavirus 1 (APyV) and beak and feather disease virus (BFDV) are among the most important in Psittaciformes. The occurrence of these agents has been widely described in various parts of the world; however, little is known about these viruses in South America. APyV and BFDV can cause high morbidity with feather alterations and even mortality. Other variable symptoms could appear depending on the host's age and taxonomic group. The aim of this study was to detect APyV and BFDV in samples of captive exotic and native Psittaciformes in Brazil. Samples from 120 birds with clinical signs compatible with APyV and/or BFDV were examined. In total, 57 (47.5%) positive birds were found, of which 21 (17.5%) had APyV and 41 (34.17%) had BFDV. Five animals (4.17%) presented concurrent infection. Phylogenetic analysis showed a divergent APyV strain and a diversity of Brazilian BFDV strains. Our study shows that these viruses are present at a significant frequency in captive exotic and native Psittaciformes in Brazil. This study also highlights the need for constant epidemiologic surveillance to preserve bird biodiversity with a focus on endangered Psittaciformes species.
