Researchers found that tick infection prevalence in Ohio has increased to 47.6%, comparable to endemic US regions like Connecticut. The study suggests that Ohio's forested areas have the same risk of Lyme disease as Connecticut.
A new study reveals that farmers in the Northeast are facing a growing threat of tick-borne diseases, which can be devastating to their livelihoods. The research found that farmers often experience multiple tick bites per month, with some contracting serious illnesses like Lyme carditis.
Researchers from North Carolina State University have confirmed a new species of Rickettsia bacteria found in dogs, associated with symptoms similar to those of Rocky Mountain spotted fever. The new species, Rickettsia finnyi, has been cultured and sequenced, and its genome revealed a unique circular chromosome.
Researchers have discovered that manganese is both an armor and a weakness for the Lyme disease bacterium, Borrelia burgdorferi. Exploiting this vulnerability could lead to new therapeutic strategies for treating the disease.
A 47-year-old man from New Jersey died after consuming beef due to a tick-borne meat allergy caused by the Lone Star tick's alpha-gal sugar. Researchers identified the allergy and its link to fatal anaphylaxis, urging physicians to investigate severe abdominal pain after eating red meat in areas with high Lone Star tick populations.
The Bay Area Lyme Foundation is offering two $150,000 grants to support research on novel approaches in Lyme disease diagnostics and treatments. The Tick-borne Pathogen Award focuses on co-infections with Borrelia burgdorferi or stand-alone investigations of non-Borrelia tick-borne pathogens.
Researchers found regions with higher numbers of potentially harmful tick species in Illinois, increasing risk of infection with multiple diseases. The lone star tick is prevalent in southern Illinois, while the black-legged tick dominates northern and central Illinois.
A new surveillance study from UNC Greensboro found a dramatic increase in Lyme disease cases in North Carolina, with blacklegged ticks expanding their range into the state. Ticks from the Blue Ridge Mountains were more likely to carry Borrelia burgdorferi, the bacteria responsible for most Lyme disease cases.
Researchers from the University of Surrey identified two novel antiviral effectors in tick cells that can reduce SFTSV replication, offering new hope for preventing tick-to-human transmission. Understanding how ticks tolerate viruses is crucial for developing effective vector control strategies and prevention methods.
The team built a high-resolution 3D structure of the Powassan virus, shedding light on its transmission and potential therapeutics. The findings could inform future treatments and preventions for this emerging tick-borne disease.

Researchers at UMass Amherst's New England Center of Excellence in Vector-borne Diseases have identified a new strain of Rickettsia bacteria that causes spotted fever infections in humans. The discovery in Maine suggests rabbit ticks could be a zoonotic vector for serious infections, contradicting the usual dog tick vector.
Researchers believe that post-treatment Lyme disease (PTLD) is caused by the body's response to remnants of the Borrelia burgdorferi cell wall, which persists in the liver. The unique structural properties of this peptidoglycan molecule promote its persistence and may lead to a stronger immune response in some individuals.
Analysis indicates a potential east-west gradient of increased red meat allergy risk in the Mid-Atlantic US due to fragmented habitats. Tick bites may play a role in triggering this condition.
Researchers identified piperacillin as an effective treatment for Lyme disease, which causes devastating symptoms in half a million individuals annually. The antibiotic works by targeting the bacteria's unique cell wall synthesis pattern, leading to its death without harming beneficial gut microbes.
Researchers found that pheasants released in the UK can carry Lyme disease bacteria in ticks, increasing the risk of human exposure. The study suggests 'spillback' from non-native species can lead to the emergence of zoonoses.
Researchers have made significant discoveries about the role of GP38 in viral infections and pathogenesis, highlighting its potential as a target for vaccines and medical countermeasures. Non-neutralizing GP38-specific antibodies have shown protective efficacy against lethal challenge, reducing circulating GP38 and vascular leak.
