Until some time ago, scientists thought that a rare and potentially deadly meat allergy was sent by just one species of tick found in the US – Lone Star Tick (Amiboma americamHowever, new reports of allergies called alpha-gall syndrome suggests that much more broad black-legged ticks (Ixodes) Can also transmit the disease.
While loan star ticks are mainly found in Southern and Eastern America, black-Legged Ticks (Ixodes scapularis), Also known as deer ticks, America and midwests and western black-legged ticks are present in the eastern half (Ixodes pacific) According to the western coast, according to Mayo Clinic,
The report of the new case states that there is a danger of tick-borne alpha-gall syndrome in a wide health in the US. However, “Evidence continues to support that in the US, most Alpha-Gal syndrome patients develop allergies after experienced by a loan star tick,” Dr. Johana SaljarThe Disease Control and Prevention Center (CDC), a veterinary medical officer and epidemic along with the co-writer of the division and co-writer of both case reports, told live sciences in an email.
Given that a variety of tick species were linked to Alpha-Gal syndrome outside the US, scientists had long suspected that black-leg ticks in the US also broadcast allergies.
“For us, it was just a loan star tick,” Jennifer plotNon-profit tick-related situation at North Carolina University in Chapel Hill was written by United and co-founder of an assistant faculty member In a blog postHe said, “Thousands of lime (a tick-borne disease) patients tell us that they cannot tolerate red meat, we have long suspected black-leased ticks and other tick species in the US,” he said.
“Although our publication is some of the first reports connecting Blacklegd ticks to Alpha-Gal syndrome in the US, but the bite from these species in the US leads to Alpha-Gal syndrome, definitely happened before these reports,” Salajar said.
In Alpha-Gal syndrome, the immune system is known as a sugar for a sugar that is known as Galactose-ฮฑ-1,3-Galactose, or “Alpha-Gal”. People who are affected can develop serious allergic reactions not only for red meat but also for medical remedies with materials, personal care products and materials from mammalian tissues, where this sugar is found.

First caseThe CDC journal Emerging infectious diseases reported in the April 4 issue, describing a man woman who developed alpha-gall syndrome after a strong black-leagged tick (I. scapularis) Cutting.
The 45 -year -old woman experienced swelling and itching at the first bite, followed by abdominal pain and nine days later after eating rabbit. In the next two weeks, digestive problems continued after consuming red meat. A serious episode of diarrhea and vomiting hours after beef was eaten inspired him to visit the health care provider 20 days after cutting the tick. Blood tests revealed high levels of alpha-gall-specific immunoglobulin E (IGE), which confirms alpha-gall syndrome. After 10 months his allergy was solved.
Second case Alpha-Gal syndrome, reported in the issue of the same magazine, included a 61-year-old wildlife biologist in Washington. After a reinforced bite from the western black-legged tick (I. Pacific)He experienced a skin rashes and lips inflammation after a serious allergic reaction, 29 days later, when he ate red meat, and emergency epinephrine (epipane) treatment was required. After the diagnosis of Alpha-Gal syndrome, he avoided meat and had no further response. A few years later, he got two more I. Pacificus The tick bites, which triggers an increase in Alpha-Gal IGE antibodies.
To date, why Alpha-Gal syndrome can be triggered by cutting tick. “We are only engaging in the science of this and other tick-related diseases-there are something that we don’t know,” the plot said.
Research Some tick species have shown alpha-gall antigen-proteins that trigger an immune response-and secrete these antigens into their saliva during feeding. It can trigger alpha-gal allergies in humans. “Ticks do not pick up animals (alpha-gall antigens) and then transmit them to humans,” the plot insisted.
“More study requires how a tick bites trigger alpha-gall syndrome in some people, and the bite from the loan star ticks causes the United States vs. Blacklegd, Western Blacklegd and why the cause of the majority of human affairs in other ticks,” Saljar said.
Preventing tick cutting is the best way to protect against alpha-gall syndrome and other tick-borne diseases Lyme disease And Pavson virus“When you estimate it to be in areas where you can tick, use an EPA-category insect distingurant and wear permethrin-exposed clothes,” Saljar advised.
