Mosquito bites may be a nuisance, but fortunately, in the U.S., they tend to amount to nothing more than that. Upon being bitten, most Americans experience a bit of swelling and itchiness, and nothing more. However, there are exceptions to this, including stronger allergic reactions to bites and cases of mosquito-borne illness.  Insect and arachnid bites, including ticks, account for approximately 2,000 cases of malaria and 30,000 cases of Lyme disease in the U.S. annually. In addition, millions of people worldwide die of malaria each year. It is helpful to protect yourself against insect bites, not only to avoid pesk...

(CNN/CBS) — The climate crisis is making us more vulnerable to ticks in an unprecedented and growing threat to public health, according to a new report. Bacterial and protozoan tick-borne diseases doubled in the United States between 2004 and 2016, the report notes, and in 2017, more than 90% of the 60,000 vector-borne diseases in the United States were linked to these particular bloodsucking bugs. The warmer temperatures brought by the climate crisis, in addition to ecological changes and reforestation, have extended the bugs’ range into regions that had not seen certain types of ticks for many decades, if eve...

Unlike typical Fur proteins in which DNA binding represses gene expression, binding of BosR to the rpoS promoter directly activates rpoS transcription in B. burgdorferi. However, virtually nothing is known concerning potential structural fea...

You have a chronic illness that is debilitating and requires meticulous management. Which is hard enough. But you also have an invisible illness—like fibromyalgia, diabetes, Lyme disease, IBS, or something very rare. On the outside, on most days, you look fine, even perfectly healthy. But on the inside, you’re struggling with unbearable migraines, knock-you-off-your-feet fatigue, dangerous digestive issues, severe pain and much more. Because people don’t see these symptoms, they misunderstand what’s going on, which leads you to feel judged and lonely. And these people might include everyone from med...

One day ago his right wrist, right ankle and bilateral knees had some swelling but no erythema or warmth. He says that he has pain in them when he moves but not when he is resting and he denies any joint stiffness or gelling. He also had 1-2 days of multiple red skin lesions on his extremities and trunk, not overlying the affected joints. The skin lesions do not come and go and do not itch. They are mainly discrete circular lesions wi...

Reading the recent letter from Stone et  al1 reminded us of a subject from our previous galactose-α-1,3-galactose (alpha-gal) study. Indeed, she may well be the same 76-year-old lady found in the letter (Table E1) who was reported as negative to alpha-gal. Her first reaction to meat started 45 minutes after eating barbecue, only a few months following her recovery from Lyme disease.2,3 Since then she has had multiple reactions of varying severity, some of which started less than 1 hour after ingestion of red meat.
