Scottish scientists in the Amazon are helping to tackle a growing threat from vampire bats, which carry the deadly rabies virus.

Researchers say more humans and livestock are being bitten by the bats because of the impacts of climate change - due to rising temperatures and changing land use.

A team led by the University of Glasgow is developing vaccines and monitoring the expansion of bat roosts in Peru, Columbia and Brazil.

Rabies kills tens of thousands annually with 40% of those deaths in under-15s, according to the World Health Organisation.

It is regarded globally as the most lethal of the infectious diseases and left untreated leads to almost-certain death in people who are unvaccinated.
