And I thought lyme disease was bad. . .
-----------------------------
There's a new weapon in the war on meat: a tiny tick, whose bite might be spreading meat allergies up the East Coast.
A bite from the lone star tick, so-called for the white spot on its back, looks innocent enough. But University of Virginia researchers say saliva that sneaks into the tiny wound may trigger an allergic reaction to meat -- agonizing enough to convert lifelong carnivores into wary vegetarians.
"People will eat beef and then anywhere from three to six hours later start having a reaction; anything from hives to full-blown anaphylactic shock," said Dr. Scott Commins, assistant professor of medicine at the University of Virginia in Charlottesville. "And most people want to avoid having the reaction, so they try to stay away from the food that triggers it."
Commins said cases of the bizarre allergy are popping up along the East Coast and into the Bible Belt, areas ripe with lone star ticks. He's already seen 400 or so. And 90 percent of them have a history of tick bites, he said.
"It's hard to prove," he said of the link between lone star ticks and meat allergies. "We're still searching for the mechanism."
Allergies are immune reactions to foreign substances, from pet hair to peanuts. As antibodies attack the substance that caused the reaction, they trigger the release of histamine, a chemical that causes hives and, in severe cases, life-threatening anaphylaxis.
Commins said blood levels of antibodies for alpha-gal, a sugar found in red meat, lamb and pork, rise after a single bite from the lone star tick. He said he hopes experiments that combine tiny samples of tick saliva with the invisible antibodies will prove the two are directly connected.
"It's complicated, no doubt," said Commins. "But we think it's something in the saliva."
Experts say the six-hour lag between exposure to meat and the allergic reaction complicates things even more.
"It's very atypical as food allergies go," said Dr. Stanley Fineman, president of the American College of Allergy, Asthma and Immunology. "Most food allergies occur very quickly. And it's also a bit unusual to see adults develop a food allergy."
But the tick bite theory could help explain the sudden onset of some meat allergies, Fineman added.
Other Common food allergens include peanuts, shellfish, milk, eggs, soy and wheat. And most food allergy sufferers are glad to discover the source of their misery, even if it means upheaval for their diets.
"Avoidance is the best way to handle any food allergy," he said.
But meat allergies are hard for some brawny barbecuers to swallow.
"Some people are totally destroyed," said Commins. "Others say, 'Maybe I'm better off without it.'" |

Of all the heinous bugs in the world, this isn't all that bad. For some people it might actually be a good change.
By the way, ticks aren't insects. |

Probably not a bad thing. If it spreads more they might even stop cutting down the rainforest for cattle ranching.

And in other news, shares in Lone Star just plummetted 50% |

I hate all insects and blood sucking arachnids. In fact we could do with arthropods all together if they weren't so ecologically important (for instance pollination etc.). |

i read about this a few weeks ago and think it's the most perfect insect i've ever heard of for this day and age. make sure they hang out at fast food joints and i think they could be frontline against the war on obesity.
seriously though, mosquitos are the worst insect in the world. scientist even believe that there would be no major impact on the food chain if they just disappeared tomorrow. |

Yes mosquitoes suck, (ha hA) but they're still an important part of the food chain. Fish eat the larvae. The adults are a staple of a lot of birds, spiders and especially bats. Your unnamed "scientist" doesn't know what she's talking about. |

there are actually quite a few articles on this bob. this is one of those situations however that if you need proof you will need to search for it. i've already read the articles and can't be bothered to search for them at the moment.
the only completely natural predators of mosquitos are dragonflies which is a juxtaposition for me because they are my favorite insect, and mosquitoes are my least favorite (by a large margin). bats might also be affected, but they eat a wide range of insects and some fruits, small animals, etc. dragonflies are the only predator that feeds mainly on mosquitos in both larvae and adult forms. |

Here's the relevant excerpt from the top google search result I did:
"Mosquito larvae are aquatic insects, and as such, play an important role in the aquatic food chain. According to Dr. Gilbert Waldbauer in The Handy Bug Answer Book, "mosquito larvae are filter feeders that strain tiny organic particles such as unicellular algae from the water and convert them to the tissues of their own bodies, which are, in turn, eaten by fish." Mosquito larvae are, in essence, nutrient-packed snacks for fish and other aquatic animals.
Their role on the bottom of the food chain doesn't end at the larval stage, of course. As adults, mosquitoes serve as equally nutritious meals for birds, bats, and spiders.
As much as we loathe them, mosquitoes represent a considerable biomass of food for wildlife on the lower rungs of the food chain. Their extinction, were it even achievable, would have an enormous adverse affect on the entire ecosystem." |

Those blogs are happy speculation that maybe things would be OK if we wiped out all the mosquitoes. But they also say that no one really knows what would happen if we wiped them all out.
Maybe black flies, midges or something even more annoying would evolve to take over the mosquito's niche, and then we'd be swamped with them instead. Little good tends to come with messing with fine ecological balance.
Rabbits in Australia anyone? |

The Japanese Hornet. I see them on the Yongsan base & along the Han river. They are pretty huge Yellow/black and look like very large Bees. They have a stinger and big ant like mandibles. I caught one a few years ago along the Han but they give chemical signals so I was chased by bee Nazis from the Han to my place in Itaewon. I ended up giving the carcass to our tomcat. |

Chairman Mao once said: sparrows are useless, kill them all. Heroic workers of glorious revolution dutifully did. Next Summer, the sacred trees of the Fatherland were infested with greedy capitalist hairy caterpilars. The enemies of the revolution also fell off the trees and landed on hard working comarades, stinging them and making them itch.
Chairman Mao said: rehabliitate comrade sparrows. |
