UK Households Are Being Warned Amid The Spread Of A Deadly Bird Disease

For the longest, the US had been dealing with bird flu, infecting now not just birds, but farm animals and humans. Amid all this, the first severe human case from Louisiana also passed away. Now, UK households are also being urged to be vigilant for the signs of a deadly disease spreading among birds, though not bird flu. This is Trichomoniasis, 'canker' or 'frounce'.

What is Trichomoniasis?

In Birds

It is a contagious infection caused by a parasite that effects human, birds and cattle. In birds, it is caused by the parasite Trichomonas gallinae. In birds, it infects the tissues in their mouth, throat, esophagus and makes it difficult for them to eat or to breathe.

In Humans

In humans, it is a sexually transmitted infection (STI) caused by the parasite Trichomonas vaginalis. The parasite was discovered by Alfred Francois Donné, a physician, who discovered T.vaginalis in 1836. He observed the parasite in the vaginal discharge of infected women. A clinically entity known as trichomoniasis was then first described in 1917 by Hohne.

In Animals

It is also found in animals, as it is a venereal disease in cattle that affects the reproductive tract and is caused by the protozoa Tritrichomonas fetus. In bulls, it is usually asymptomatic, but can spread during breeding, and in cows, it could lead to early fetal death, abortion, infertility, and pyometra.

What UK Is Worried About?

In UK, it is the bird trichomoniasis that has been seen. This parasite is commonly found in the upper gastrointestinal tract of adult pigeons and doves and can be transmitted to their young during the feeding process. It could also contaminate food and water resources, especially bird feeders and birdbaths. It also infects yellowhammers, goldfinches, dunnocks, and bullfinches among others.

The Royal Society for the Protection of the Birds (RSPB) also pulled flat bird feeders from sale on its website, as it also contributed to the spreading of the illness. This is because bacteria from decaying food and waste from seed husks can build up in a flat feeder and increase the risk of infection. People are thus being advised to look out for signs of sick birds in their garden, with symptoms which includes:

• Lethargic birds
• Puffed-up plumage
• Birds who have difficulty maintaining balance

As per the British Trust for Ornithology, swelling of the neck may also occur, while the feathers around the beak may appear wet. Affected birds also drool saliva and excrete a greenish fluid or a cheese-like substance from the beak.

Is There A Disease Management?

As per the Wisconsin Department of Natural Resources, Not all birds that are infected with this parasite become sick. Once the noticeable lesions appear, affected birds generally are at risk of starvation or suffocation. Control of trichomoniasis in wild birds includes reducing potential transmission to unaffected birds. When visibly affected birds are present, bird feeders and birdbaths should be removed and disinfected with a 10% bleach solution. Feeders and baths should not be put back up until the affected birds are gone from the area.

Furthermore, the good news is that this parasite, found in birds, do not infect people.
