US Biologic/CAES Report Field Trials of Orally Delivered Anti-Lyme Vaccine Targeting the Field Mouse
January 14, 2020
The Connecticut Agricultural Experiment Station (CAES) and US Biologic announced the publication of field trials showing the effectiveness of the delivery of an orally-delivered anti-Lyme vaccine targeting the major wildlife source of Lyme disease, the white-footed mouse.
Long-underfunded Lyme disease research gets an injection of money—and ideas
April 17, 2019
Months after a U.S. Congress–mandated working group sounded the alarm about tickborne illnesses and urged more federal action and money, the National Institutes of Health (NIH) is readying a strategic plan for these diseases. Last week it also, serendipitously, issued a rare solicitation for prevention proposals in tickborne diseases. The new pot of money, $6 million in 2020, represents a significant boost; NIH spent $23 million last year on Lyme disease, by far the most common tickborne illness, within $56 million devoted to tickborne diseases overall.
Vaccinating Mice May Finally Slow Lyme Disease
January 29, 2019
Kirby Stafford, Connecticut’s state entomologist, knows only one surefire way to reduce tick populations enough to cut Lyme disease rates: killing deer. Otherwise, he says, “very little by itself really reduces tick numbers enough.”
But in some Connecticut neighborhoods Stafford has been testing a new strategy, one he hopes might show real promise after years of stymied efforts to drive new Lyme infections down: a vaccine for mice.
Study shows increase of Lyme disease in dogs
December 28, 2018
The condition in canines is rising in states traditionally not considered to be high-risk, suggesting human endangerment may also be increasing in these areas.
Lyme disease in dogs has become increasingly common in the Northeast and has moved into U.S. regions not historically considered endemic.
CDC warns of exotic ticks spreading across the nation that may carry diseases
December 3, 2018
“The Centers for Disease Control and Prevention is investigating a tick that is spreading widely across the United States.
Nine states have reported finding the Asian longhorned tick, which is known to carry a variety of pathogens. The CDC said late last week it is investigating how the tick could impact the U.S.”
Zoonotic Implications of Changing Tick Populations
October 25, 2018
“Practitioners in both veterinary and human medicine must remain aware of the changing geography of ticks and associated vector-borne diseases. The discovery of the Asian tick H longicornis in New Jersey and Virginia should be an important reminder of the fact that ‘ticks and tickborne pathogens do not recognize international boundaries.’ Thus, ‘a robust international disease monitoring network’ is needed to protect both human and animal health from both known and emerging tick-borne diseases.”
US BIOLOGIC Note: This summary is based on a review article published in the June 2018 issue of Veterinary Sciences and authored by Dr. Stephen Wikel, US BIOLOGIC‘s senior science advisor.
Where Is Lyme Disease? Now In All 50 States And Washington, D.C.
August 7, 2018
“This really bites and sucks. The tick population continues to grow, Lyme Disease continues to spread, and now according to a recently released analysis from Quest Diagnostics Lyme Disease can be found in all 50 states plus Washington, D.C.”
An Invasive New Tick Is Spreading in the U.S.
August 6, 2018
“For the first time in 50 years, a new tick species has arrived in the United States — one that in its Asian home range carries fearsome diseases. The Asian long-horned tick, Haemaphysalis longicornis, is spreading rapidly along the Eastern Seaboard. It has been found in seven states and in the heavily populated suburbs of New York City.”
An Army of Deer Ticks Carrying Lyme Disease Is Advancing and Here’s Why It Will Only Get Worse
August 6, 2018
“The spread of Lyme disease has followed that of deer ticks. The incidence of Lyme has more than doubled over the past two decades. In 2016, federal health officials reported 36,429 new cases, and the illness has reached far beyond endemic areas in the Northeast to points west, south and north.”
Tick Discovery Highlights How Few Answers We Have about These Pests in the U.S.
June 26, 2018
“Other ticks, such as lone star ticks, carry diseases, too, including Rocky Mountain spotted fever, ehrlichiosis and tularemia; yet we know even less about where these ticks are or how their populations are changing.”
The Growing Global Battle Against Blood-Sucking Ticks
August 25, 2015
On a balmy day in late June, Scott Williams waits for a white-footed mouse (Peromyscus leucopus) to fall asleep. Williams, a wildlife biologist with the Connecticut Agricultural Experiment Station in New Haven, has just transferred the animal from a trap to a plastic bag containing a cotton ball doused in anaesthetic. As soon as the mouse's breathing slows to one breath per second, Williams will take it out, draw blood, weigh it, put an ear tag on it for identification and check the animal for ticks, saving any that are engorged with blood. He must work quickly. The mouse will wake up in about two minutes, and she might be grumpy.
