Pathogenic Yeasts Found in Bird Feces
The study revealed that fresh bird droppings contained five of the six ascomycetous yeast species (Candida spp.) listed by the World Health Organization as particularly hazardous. Additionally, two other yeast species, though not officially classified as highly pathogenic, were also frequently detected and are known to cause yeast infections.
“This means that contact with bird droppings, or accidental ingestion, can pose an infection risk, especially for children and people with weakened immune systems,” university experts said. They recommended avoiding contact with droppings and washing hands thoroughly after being in areas populated by birds.
Comprehensive Study Across Multiple Bird Species
Scientists analyzed droppings from nearly 200 birds, including pigeons, European starlings, white wagtails, great tits, and house sparrows. They identified a total of 638 yeast strains across nine species. Pigeons were found to carry the highest diversity of potentially pathogenic yeasts, making their droppings the most concerning from a health perspective. While harmful microorganisms were also present in dried droppings, their numbers were lower.
Legal Implications in Russia
Previously, legal expert Lyudmila Aivar reminded the public that individuals in Russia can face fines if pigeon droppings remain in areas where birds are fed. This adds a civic dimension to the health warnings, emphasizing the need for careful management of urban bird populations.
