A parasitic worm that was deemed not to be infected is a cow that has started to infect, mating in our eyes. Scientists are aware of the reasons why the worm is suddenly causing disease in humans and warning that this is an emerging trend.
Scientists from regional laboratories and Disease Control and Prevention Centers (CDCs) identified the worm as it was Thelazia gulosa, beef type called cattle eye worm. As its name suggests, these worms grow within the impervious cow barriers. The first case of this infection in humans was identified in 2017 in Oregon's wife, and now a second infection was reported by researchers in a report on 22 October in the journal. Clinical Infectious Diseases.
“That the second person must be infected T. gulosa It has occurred within 2 years of its first showing that it is an emerging zoonotic disease in the United States, ”the authors wrote.
T. gulosa now it goes with two other species Thelazia people are known to have an infection, and it is likely that the number of human infections from these worms is also growing.
According to a recent case report, a woman who spent winter in California was running a track in a regional park in 2018 when she rounded a corner and ran into swarms of small flies. She recalled the flies to be strayed and spitting them from her mouth. Next month, she began to notice irritation in her right eye. She washed it with tap water and flushed two moving worms. After a few doctor's visits, and constant washing with distilled water, two more worms were removed.
In total, there were four worms in the patient's eyes, while Oregon's wife had a woman.
One of the worms was sent to scientists at the State Public Health Laboratory in California by the second patient doctor, who recognized it as some form. Thelazia worm, which primarily infects cats, dogs and cattle. For more specific identification, the laboratory sent the sample to the CDC Parasitology Diagnostic Laboratory.
“[The CDC is] The final stop when you get something and you don't know what it is, ”said Richard Bradbury, the first author in the report led by the CDC's laboratory at the time.
Yes, scientists found that the worm was the same species as the worms that were added a year earlier from infection in the eyes of Oregon woman. Bradbury said that it was much easier to identify the worm this time around – in the previous case, he wasn't sure what it was that he got the 1928 paper in German which described the species.
T. gulosa it is a parasitic worm that requires a vector species to reproduce and spread. Flies emit maturity T. gulosa worms into the eyes of cattle, where do the mate worms. Their larvae are spread through cattle tears and pus. These animals often like the atmosphere, and larvae larvae hatch within the flies and begin the cycle again.
In the second eye of the second patient sent to the CDC in 2018, the eye was pulled by unfertilised eggs with larvae, which allowed the worms to reproduce in a human host.
“Woman and female adults had worms in their eyes, and it was clear that they were able to cope with it,” Bradbury said. “It's romantic in a way, isn't it?” T
“However, they were getting sex in their eyes and one of them is pregnant and has children, but these children cannot be adults in the eye… he must first find a flight,” he said.
For an explanation of this phenomenon, the scientists have bupkus. “The causes of this species are only people who are now infected,” they wrote in the paper.
Since the face species are transmitted T. gulosa it was introduced in North America immediately after the Second World War, and the number of worm-infected faces may increase as cattle populations have grown. This could increase the likelihood of cattle eye worm infection occurring, although it is too early to know for sure, Bradbury said.
This type of worm infections is “extremely rare” in humans, according to Bradbury. You are 26 times more likely to win the lottery than one of these infections, he said.
The best thing you can do to avoid such an infection is that a shoe goes away from your eyes, says Bradbury. However, anyone suspected of having a worm infection in their eyes should see a medical professional, he added – the symptoms are conjunctivitis and they feel a worm in your eye.
