Human bacteria kill English hedgehog


This video from England says about itself:

In the gardens of London during the hours of darkness in springtime, a strange and fascinating ritual is taking place – hedgehog mating. This entertaining clip shows David Attenborough examining how these prickly creatures get intimate. From the BBC’s Life of Mammals.

Human sore throat bacteria found to have led to the death of a hedgehog

A post mortem carried out by the Zoological Society of London’s (ZSL) Institute of Zoology has, for the first time, identified that a human sore throat pathogen was responsible for the death of a wild hedgehog.

The free-living European hedgehog (Erinaceus europaeus) was found dead in northern England and a post-mortem examination and detailed laboratory testing confirmed the presence of the pathogen Streptococcus pyogenes, typically found in humans with sore throat or rash-like symptoms.

The pathogen was characterised as emm 28, a strain associated with invasive disease in humans. The discovery is the first known report of this human pathogen in a hedgehog, and in any free-living wild animal, as confirmed by gene sequencing.

The pathogen was determined to be the cause of death in the hedgehog, the bacteria having likely entered the body via a tooth root abscess, before spreading to other tissues.

A paper, written by Lydia Franklinos, a wildlife veterinarian within ZSL’s Institute of Zoology, and published in EcoHealth, hypothesises that the case may have resulted from the transfer of infection from human to hedgehog via anthroponotic infection, or reverse zoonosis.

It is thought that the opportunities for direct and indirect contact between wild hedgehogs and humans could be a possible explanation for this unexpected finding.

Franklinos says: “While it is more common to hear about zoonotic diseases originating from wildlife, we rarely encounter disease transferring from human to animal, as appears to be the case here.

“We need to be vigilant, and continue to monitor the threat to wildlife from humans and their activities.

“The hedgehog is in decline in the UK, and I would encourage further research on the pathogens of hedgehogs to better understand disease threats to the species in order to inform conservation efforts.”

The post mortem was carried out as part of Garden Wildlife Health (www.gardenwildlifehealth.org), an initiative which aims to monitor the health of, and identify disease threats to, British wildlife.
