Protection against ticks.

Protection against ticks. Lyme disease may be prevented with a single injection, according to research published in the Journal of Medical Microbiology. The United States saw nearly 20,000 cases of Lyme disease in 2006. Now, scientists at the Centers for Disease Control and Prevention (CDC) in Fort Collins, CO, have developed an injection that protects against two severe diseases transmitted by tick bites: Lyme disease and anaplasmosis. Currently, there is no vaccine to protect against either, but scientists involved have shown that a single injection of sustained-release antibiotics can prevent both diseases in mice. While a single oral dose of doxycycline is only 20% to 30% effective at preventing these diseases in mice, researchers found that a new formulation of doxycycline hyclate that is programmed to release the drug over a 20-day period is 100% effective. Scientists say that a slow-release patch could be used in conjunction with current recommended protection against ticks, such as repellents and good old-fashioned personal tick checks.
