Eubacterial fluorescence in situ hybridisation and histologic features in 25 dogs with gallbladder mucocele.

FISH was more sensitive for detection of bacteria in gallbladder mucoceles when compared to bacterial culture of bile. Cholecystitis was common in dogs with gallbladder mucocele. Further study is required to elucidate the relationship of cystic mucinous hyperplasia, bacteria and cholecystitis in the aetiopathogenesis and progression of gallbladder mucocele.
