Scabies in Bwindi
At the end of July, the Ugandan park authorities asked the Mountain Gorilla
Veterinary Center to examine the gorillas in the Nkuringo group that is
currently being habituated. The animals had lost hair and scratched themselves
more than usual. Three young animals had an abnormal skin condition. One
gorilla was anaesthetized, as it had lost about 60% of its hair and its
skin was coming off in flakes. The MGVC took samples of the diseased skin
and took biopsies. A microscopic examination indicated skin mites. The
animal was drip-fed, as it showed signs of being dehydrated. Two other
young animals were treated with an ectoparasitic ointment without being
anaesthetized.
A week later, one of them was treated again. After another week, all three
animals' condition had markedly improved. However, at the end of August,
in one case another follow-up treatment with the ectoparasitic medicine
was necessary. In addition, a newly infected young gorilla had lost a
lot of hair on the chest and also had to be treated. One young animal
received its follow-up treatment from an Australian colleague from Uganda,
as the silverback shielded it from the rest of the group while the veterinarians
were there.
At the moment, all animals are in good condition. No additional individuals
fell ill. The samples were sent to parasitologists in the USA in order
to determine whether the mites were a species that normally infects humans
or other mammals. To date, there is no final result. Scabies mites are
considered very host specific. However, the mite in question does not
seem to be an autochthonous gorilla parasite, as the young animals showed
a strong reaction.
In early August, the IGCP called a meeting with the Ugandan park authorities,
the ITFC (Institute of Tropical Forest Conservation) and the Mountain
Gorilla Veterinary Center. The local park authorities expressed their
concern about the disease. Preventative measures are to be taken. The
MGVC was asked to develop a questionnaire and give training that would
enable rangers and possibly other people living close to the park to recognize
early signs of gorilla diseases. This has since been done. Park authorities,
IGCP (International Gorilla Conservation Programme) and ITFC are
planning additional measures.
