Leprosy was first found in wild chimpanzees.

An ancient disease in humans seems to have crossed the species barrier to one of our closest primate cousins. On Wednesday, researchers conducted a detailed investigation into leprosy cases between the two sects.Rate group of chimpanzees in West Africa – first documented between wild champs. The cause of the outbreak is unknown, but the disease is thought to be rare in the wider Champ community.

There is leprosy. Due to By bacteria Mycobacterium leprae, Making it a relative of the TB bacteria. Like a virus, and Unlike most other bacteria, leprosy bacteria survive by invading our cells and hijacking their functions. Adding to its bizarre nature, post-infection symptoms may not appear for years or decades. These include initially yellow-looking wounds or sores. OhOver time, chronic infections can also slowly destroy nerves and eye cells, causing symptoms such as numbness, paralysis, blindness, and permanently deformed limbs.

Our history of leprosy, also known as Hansen’s disease, dates back to Bible times. But despite the terrible concept, it has been going on for a long time, leprosy is a pushover thing. The disease is not easily transmitted, usually requires contact with a close person for months, and there are 95 people. Guessed Being naturally protected from infection. While bacteria developed resistance to the earliest drugs used to treat it in the 1940s, The infection is treatable for a long timeThe term antibiotic therapy

Improved sanitation and the availability of antibiotics have made leprosy a rare disease worldwide. But there are still pockets in the world where these resources are not so great, and there were about 200,000 cases. Reported In 2019. In the 1970s, researchers. Discovered that Humans are not the only natural hosts for bacteria: a.Rmadillos in the US now take it regularly, Also, A process that probably began when Europeans settled the New World and brought bacteria with them. In a favor Twist, leper armadillos occasionally Infected Man just back

Studies show that captive chimpanzees can also get leprosy. but IIn June 2018, researchers studying wild champs in West Africa found strange leprosy-like lesions on one. Adult male champ His name was Woodstock. The discovery left them wondering if similar symptoms had ever occurred in the same community or elsewhere.

By looking at the tissue samples obtained after Champ’s death, they identified a champ named Zora, whose blood showed signs of leprosy bacteria before his death from a leopard attack in 2009. Inspect photos later. زورا۔ Skin lesions that could have been caused by leprosy, while stored samples. Advised that the infection has started at least seven. Years ago, the group finally managed to find several other cases of leprosy between the two champion communities in C ڈیte d’Ivoire and Guinea-Bissau.

“This is the first case of leprosy in non-human animals in Africa,” said lead author Kimberly Hawkings, a researcher at the Center for Ecology and Conservation at the University of Exeter in the UK. Statement From university. “It’s amazing that this also happens to our closest living relative, the chimpanzee, especially considering how good chimpanzees study in the wild.”

Here are the team’s results. Published Wednesday in nature.

Although the main culprit for this. How these champs catch leprosy will be human, researchers are not so sure. Genetically, stress is found in every Champ community. They were different from each other, and they are rarely found in other human or animal habitats. Nor does the champ community spend much time around humans, Either way, making the already difficult process of transmission less understandable. So it is possible that leprosy is currently making its home in more non-human species than previously thought. And that Champs caught it from these unknown hosts. Interestingly, scientists in the UK. Found Evidence in 2016 that squirrels can catch leprosy Also.

The good news is that leprosy is rare. For example, out of 467 chimpanzees observed in Guinea-Bissau in recent years, the researchers identified only four cases, including the origin of wood stocks. But wild. Chimpanzees, unlike humans, do not have access to antibiotics. And researchers. There are fears that local leprosy could still damage these champs. He says more research is needed to understand the spread and origin of leprosy in wild champ populations.

“Western chimpanzees are in grave danger, so the loss of a few people could be significant,” Hawkings said.
