Innate Immunity Never “NODs” Off: NLRs Regulate the Host Anti‐Viral Immune Response

Immunological Reviews, Volume 330, Issue 1, March 2025.
ABSTRACT A robust innate immune response is essential in combating viral pathogens. However, it is equally critical to quell overzealous immune signaling to limit collateral damage and enable inflammation resolution. Pattern recognition receptors are critical regulators of these processes.

Individual variation underlies large‐scale patterns: Host conditions and behavior affect parasitism

Ecology, Volume 106, Issue 1, January 2025.
Abstract Identifying the factors that affect host–parasite interactions is essential for understanding the ecology and dynamics of vector‐borne diseases and may be an important component of predicting human disease risk. Characteristics of hosts themselves (e.g., body condition, host behavior, immune defenses) may affect the likelihood of parasitism ...

Transmission of Severe Fever with Thrombocytopenia Syndrome Virus to Human from Nonindigenous Tick Host, Japan

Emerging Infectious Diseases
We report a human case of severe fever with thrombocytopenia syndrome virus infection transmitted by a tick, confirmed by viral identification. Haemaphysalis aborensis, a tick species not native to Japan that has been observed to transmit the virus to ...

Tick-borne infections in human and animal population worldwide [PDF]

Veterinary World, 2015
The abundance and activity of ectoparasites and its hosts are affected by various abiotic factors, such as climate and other organisms (predators, pathogens and competitors) presenting thus multiples forms of association (obligate to facultative ...

The Emergence of Another Tickborne Infection in the 12‐Town Area around Lyme, Connecticut: Human Granulocytic Ehrlichiosis [PDF]

The Journal of Infectious Diseases, 2000
Human granulocytic ehrlichiosis (HGE) is an emerging tickborne infection, increasingly recognized in areas in which Lyme disease is endemic, but there are few data on the incidence of HGE. Prospective population-based surveillance was conducted in the 12-town area around Lyme, Connecticut, by means of both active and passive methods, from April through

Asymmetric Biotic Interactions Cannot Be Inferred Without Accounting for Priority Effects

Ecology Letters, Volume 27, Issue 9, September 2024.
This study explores the influential role of priority effects, that is, the order of habitat colonisation, in shaping our ability to detect asymmetric biotic interactions. Using a simple set of simulations, we demonstrate that common approaches to detect interactions from cross‐sectional binary co‐occurrence data alone cannot make reliable inferences ...

Coxiella burnetii serostatus in dromedary camels (Camelus dromedarius) is associated with the presence of C. burnetii DNA in attached ticks in Laikipia County, Kenya

Zoonoses and Public Health, Volume 71, Issue 5, Page 503-514, August 2024.
Abstract Aims Q fever is a globally distributed, neglected zoonotic disease of conservation and public health importance, caused by the bacterium Coxiella burnetii. Coxiella burnetii normally causes subclinical infections in livestock, but may also cause reproductive pathology and spontaneous abortions in artiodactyl species.

Establishment of Amblyomma maculatum Ticks and Rickettsia parkeri the Northeastern United States

Emerging Infectious Diseases
We document a case of Rickettsia parkeri rickettsiosis in a patient in Connecticut, USA, who became ill after a bite from a Gulf Coast tick (Amblyomma maculatum). We used PCR to amplify R. parkeri DNA from the detached tick.

Human Granulocytic Anaplasmosis and Anaplasma phagocytophilum

Emerging Infectious Diseases, 2005
Human granulocytic anaplasmosis is a tickborne rickettsial infection of neutrophils caused by Anaplasma phagocytophilum. The human disease was first identified in 1990, although the pathogen was defined as a veterinary agent in 1932. Since 1990, US cases
