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.
Other Tick-Borne Diseases
One tick bite can give people more than one tick-borne disease (co-infection). In addition to Lyme disease, here are some other tick-borne diseases found in the US.
In a recent article published by the Centers for Disease Control (CDC), authors detected Borrelia miyamotoi in ticks from 19 states in the US. Investigators tested 39,198 ticks for B. miyamotoi that were submitted to the public tick testing program at the University of Massachusetts during May 2013–December 2019. All ticks tested were found on […]
A recent study published in the CDC’s Emerging Infectious Diseases journal finds ehrlichiosis and anaplasmosis can also be transmitted through blood transfusions or organ transplants. The article states, “Since 2000, ehrlichiosis and anaplasmosis cases in the United States have increased substantially, resulting in potential risk to transplant and transfusion recipients.”
In a recently published review article,* authors provide a comprehensive summary of treatment options for pregnant patients with less common bacterial, fungal, and viral infections, including several tick-borne diseases (Lyme disease, ehrlichiosis, human granulocytic anaplasmosis, human monocytic ehrlichiosis, babesiosis, and Rocky Mountain spotted fever). This review provides guidance to clinicians based on the most recently […]
In a recent article, investigators describe multiple cases of organ transplant derived Ehrlichiosis infections in donor recipients. Two cases of ehrlichiosis were reported to the Organ Procurement and Transplantation Network (OPTN) and the Centers for Disease Control and Prevention (CDC) for investigation in 2020. These two kidney recipients from a common donor developed fatal ehrlichiosis-induced […]
According to the Tulane news, a three-year, $4.8 million initiative funded by The Steven and Alexandra Cohen Foundation, will establish the Bartonella Research Consortium with the goal of developing a novel treatment for bartonellosis. There are over 40 known Bartonella species/subspecies and at least 17 of these species/subspecies have been associated with a spectrum of debilitating […]
Ohio State University researchers have just published on their creation of nanobodies which target the protein that causes E. chaffeensis bacteria to be extremely infectious. It is thought that these nanobodies can be developed as a new or complementary therapy for human monocytic ehrlichiosis as well as other tick-borne diseases that are caused by intracellular infections, infections that can be fatal if left untreated or undertreated.
New study summarizes human surveillance data from 2011-2018 in the United States for Babesia infections reported to the Centers for Disease Control and Prevention (CDC) through the National Notifiable Diseases Surveillance System (NNDSS). Data shows an increasing trend of reported Babesia cases (14,159 total) during this time period, with white men in the middle and […]
Pfizer has received priority review for their vaccine, TicoVac, that protects against tick-borne encephalitis. This tick-borne virus can cause meningitis and trigger long-term neurological symptoms. If approved, the vaccine would potentially protect travelers as well as members of the US military that are deployed to regions where the virus is common, such as Europe and parts of Asia.
