Rickettsia buchneri sp. nov., a rickettsial endosymbiont of the blacklegged tick Ixodes scapularis. [PDF]

Int J Syst Evol Microbiol, 2015
We obtained a rickettsial isolate from the ovaries of the blacklegged tick,Ixodes scapularis. The isolate (ISO7T) was grown in theIxodes ricinusembryonic cell line IRE11. We characterized the isolate by transmission electron microscopy and gene sequencing. Phylogenetic analysis of 11 housekeeping genes demonstrated that the isolate fulfils the criteria

Investigation of the Blood Microbiome in Horses With Fever of Unknown Origin

Veterinary Medicine and Science, Volume 11, Issue 2, March 2025.
ABSTRACT Background Fever of unknown origin (FUO) without a respiratory component is a frequent clinical presentation in horses. Multiple pathogens, both tick‐borne and enteric, can be involved as etiologic agents. An additional potential mechanism is intestinal barrier dysfunction.

Tick-Borne Pathogens Anaplasma phagocytophilum, Babesia odocoilei, and Borrelia burgdorferi Sensu Lato in Blacklegged Ticks Widespread across Eastern Canada

Journal of Biomedical Research & Environmental Sciences, 2022
Blacklegged ticks, Ixodes scapularis, can transmit single or multiple infections during a tick bite. These tick-borne, zoonotic infections can become chronic and cause insidious diseases in patients. In the present tick-pathogen study, 138 (48.9%) of 282

Potential diseases and parasites of white-tailed deer in Missouri (2013) [PDF]

, 2013
White-tailed deer are susceptible to a variety of diseases, parasites and injuries. Although these conditions do not account for a large percentage of annual statewide deer mortality (typically less than 5 percent), in some situations disease or parasite

Historical Summary of Tick and Animal Surveillance Studies for Lyme Disease in Canada, 1975–2023: A Scoping Review

Zoonoses and Public Health, Volume 72, Issue 1, Page 9-22, February 2025.
ABSTRACT Introduction Lyme disease (LD) is caused by infection with the bacteria Borrelia burgdorferi sensu lato (Bb) through the bite of an infected Ixodes spp. tick. LD has emerged as a public and animal health issue in Canada, with human incidence increasing in part due to the expansion of Ixodes scapularis ticks and their vertebrate hosts.

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 ...

Strain-Dependent Assessment of Powassan Virus Transmission to Ixodes scapularis Ticks

Viruses
Powassan virus (POWV) is an emerging tick-borne encephalitic virus in Lyme disease-endemic sites in North America. Due to range expansion and local intensification of blacklegged tick vector (Ixodes scapularis) populations in the northeastern and upper ...
