Key result
FAdV-4 impairs cardiac integrity indirectly, with pericardial effusion driven by vascular exudation rather than direct cardiotoxicity.
Why the study?
The mechanism of FAdV-4-induced cardiac damage and formation of pericardial effusion in hydropericardium syndrome was unclear.
Comparison
FAdV-4 infected vs control groups
Design
In vivo and in vitro experimental study

FAdV-4 triggers CM apoptosis and inflammation in poultry; hypothesis-generating for viral myocarditis mechanisms and leaves open human translation.
Niu et al. (2018) studied Fowl adenovirus serotype 4 (FAdV-4) infection. FAdV-4 infection vs. Control was evaluated on Cardiac damage, apoptosis, and inflammatory reactions. FAdV-4 infection impaired cardiac integrity in vivo, but in vitro results indicated the heart is not the target organ and pericardial effusion derives from vascular exudation.
