New adenovirus in bats, Germany

Area of Science:

• Virology
• Mammalogy
• Ecology

Background:

• Bats are reservoirs for diverse viruses, some with zoonotic potential.
• European bat populations harbor various viral agents, including lyssaviruses.
• Understanding chiropteran viruses is crucial for public health and wildlife conservation.

Purpose of the Study:

• To investigate viral infections in deceased bats from southern Germany.
• To identify and characterize novel viral pathogens in bats.
• To assess the potential for inter-bat virus transmission.

Main Methods:

• Virological screening of tissue samples from 55 deceased bats (12 species).
• Isolation and identification of viral agents.
• Analysis of viral distribution and potential transmission routes.

Main Results:

• A novel adenovirus was isolated from two Pipistrellus pipistrellus bats.
• This adenovirus represents a rare chiropteran virus isolate in Europe, distinct from lyssaviruses.
• Evidence suggesting adenovirus transmission among bats was detected.

Conclusions:

• The discovery of a new bat adenovirus expands the known virome of European bats.
• The findings indicate a potential role for Pipistrellus pipistrellus bats in adenovirus circulation.
• Further research is warranted to understand the epidemiology and implications of this bat adenovirus.
