A new University of Copenhagen study reports a previously unknown hiding place for the genes that make bacteria resistant to antibiotics. The prevailing belief that resistant bacteria will lose their resistance genes during a break from antibiotic use has been challenged by the findings of this new study. This study shows that resistance genes have […]
This Research Articles section includes articles on cutting edge research or on research which has been conducted on already existing research to either substantiate it or question its findings. The Peer Review Articles submenu sections includes only research in peer-reviewed journals–in which a panel of experts in the same field as the authors reviews the articles prior to publication to ensure scientific quality. The Professional/Govt Articles submenu contains articles by professionals or government without those articles going through the peer-review process.
This review summarizes the health burden of human babesiosis emerging on a global scale. Authors discuss tools used to monitor the frequency and location of disease as well as demographics, modes of transmission and the location of human babesiosis. Authors further describe the causative Babesia spp. in North and South America, Europe, Asia, Africa, and […]
The Journal of Medical Entomology has published a recent article regarding utilization of integrated tick management (ITM). Researchers studied the effects of “configuration of bait box deployment” on the reduction of tick burden in a suburban/rural landscape. Researchers additionally investigated bait consumption and white-footed mouse (P. leucopus) abundances as a measure of the usage and […]
In a newly published article in the IOS Press, researchers identified the Borrelia burgdorferi spirochete, the causative agent of Lyme disease in autopsied brain tissue of patients diagnosed Alzheimer’s. In addition, they found a significant number of Borrelia-positive aggregates with a known biofilm marker, alginate. Immunohistochemical data also showed that Borrelia-positive aggregates co-localized with amyloid […]
Most southwestern detection of Borrelia burgdorferi pathogen in the midwestern US to date. In a recently published article, researchers present their findings of tick surveillance surveys conducted in summer of 2019. Surveys focused on the eastern counties of the state where 266 ticks were collected and 3 species were identified. Twenty two Ixodes scapularis were collected from 5 […]
A recent article published in the Journal of Medical Entomology, describes host associations of larval and nymphal Ixodes scapularis (blacklegged ticks) collected from eight lizard species. Researchers collected from 2 to 3 sampling arrays at 5 field sites in the southeastern US, including North Carolina, Tennessee, South Carolina, Alabama, and Florida. Samples were collected at […]
Dowling, A., Young, et al., published a report in Journal of Medical Entomology with the results of a cooperative effort to survey ticks throughout Arkansas to better understand the heavy impacts of TBDs such as spotted fever rickettsiosis and ehrlichiosis in the mid-south. Logistical and financial barriers, and expanding geographic area of concern, prompted researchers to collaborate with members of the public to gather data on human disease-causing pathogens carried by ticks.
Nature Microbiology recently published an article where researchers identified a sugar that influences cell wall function in Borrelia spirochetes. Authors state that Borrelia burgdorferi bacteria produces glycan chains in the cell wall where MurNAc is occasionally replaced with an unknown sugar. Investigators identified that B. burgdorferi produces glycans that contain GlcNAc–GlcNAc. Chitobiose is the unusual disaccharide, […]
In a recent article, Johns Hopkins presents its newly developed tool, the Lyme and Tickborne Disease (TBD) Dashboard which tracks tickborne diseases at a global scale and displays maps and spatial data sets utilizing unique geographic context and includes a search function to find out what the incidence is in your US county. This initiative was […]
Heidi K. Goethert, et al., published, “Incrimination of shrews as a reservoir for Powassan virus,” in Communications Biology. The study examines Powassan virus lineage 2 (deer tick virus), and the growing threat the pathogen poses to American public health. Powassan virus is known to cause severe neurologic disease although its life cycle in nature is poorly understood.
