Summary: Due to climate and land use changes, tick populations in Canada have changed, leading to an increased risk of tick bites and exposure to tick-borne pathogens, especially in eastern Canada. Veterinary recommendations for preventing tick infestations include regular use of tick prevention products and tick checks. However, there is a lack of research on tick species-specific infestation patterns on dogs and cats, and more studies are needed to guide targeted tick checks.

Summary: The study determined the supercooling point (SCP) values for questing D. variabilis adults near Blackstrap Provincial Park in Saskatchewan, showing variation in cold tolerance abilities among individuals but no significant difference based on gender or weight. Further research is needed to understand the factors contributing to the variation in SCP values among questing D. variabilis adults.

Summary: This study discovers the importance of iron for the replication of Anaplasma marginale, a pathogen causing bovine anaplasmosis, in tick cells. It identifies the involvement of specific proteins in iron transport and their differential expression in response to iron levels in host cells. This foundational work could lead to interventions to prevent bovine and human anaplasmosis.

Summary: Reported human cases of Colorado tick fever in the western United States have decreased dramatically in the past few decades. This study conducted surveillance on Dermacentor ticks in recreational sites in Colorado, Wyoming, and California, and found that CTFV is still prevalent in certain tick species in these states. The decrease in reported disease does not appear to be due to the disappearance or decline in prevalence of this virus, indicating the importance of continued monitoring.

Summary: This study retrospectively analyzed tick species and quantity recovered from humans in Alberta over a 19-year period, and conducted molecular testing for pathogens associated with Ixodes scapularis and I. pacificus. Dermacentor ticks were the most common, followed by Ixodes and Amblyomma. The risk of tick-borne pathogen exposure, such as Lyme disease, in Alberta remains low.

Summary: Through mixed infection and cell culture experiments, it was demonstrated that infection with Rickettsia bellii inhibits the replication and establishment of Anaplasma marginale in Dermacentor andersoni ticks. This study highlights the importance of the microbiome in tick-borne disease transmission and may provide potential avenues for controlling the spread of A. marginale.

Summary: The tick midgut is crucial for the development and transmission of tick-borne pathogens, and a primary cell culture system derived from tick midgut tissues has been successfully developed to study the interactions between Anaplasma marginale and tick cells. Infection of the midgut cells by A. marginale was observed, and the differential expression of tick alpha-(1,3)-fucosyltransferases A1 and A2 was regulated upon infection. The study suggests that A. marginale utilizes core alpha-(1,3)-fucose of N-glycans to infect tick midgut cells.

Summary: The study shows that non-Ixodes tick species can effectively acquire POWV II by feeding on viremic hosts, maintain infection through molting, and successfully transmit the virus to naive hosts at comparable rates across all three species.

Summary: The study investigated the effect of tick hormones on the transmission and proliferation of tick-borne bacterial pathogens in tick bodies and ovaries, revealing that 20-hydroxyecdysone (20E) has a regulatory effect on this process. This research contributes to a better understanding of the mechanisms of tick-borne bacterial pathogens.

Summary: This study investigates the impact of tick microbiome on pathogen acquisition, maintenance, and transmission. The results suggest that tick microbiome composition and diversity are influenced by the tick's life stage, sex, and geographic region. The most abundant genera identified were Allofrancisella and Francisella, and certain bacteria species were found to be more prevalent in different regions. These findings demonstrate the importance of considering tick microbiome in understanding tick-borne diseases.

Summary: The study confirmed through morphological and molecular identification that the predominant Dermacentor species found on pets in the United States is Dermacentor variabilis, with higher prevalence in Rocky Mountain states. These data support the interpretation that D. variabilis is the major species associated with pets throughout the United States.

Summary: The turn of the twentieth and twenty-first centuries saw changes in the range of many pathogens and their vectors. The increase in the number and spread of Dermacentor reticulatus ticks since the 1990s may be due to changes in temperature and land use. Expansion of mammal hosts and predatory mammals may also contribute to the rise of new tick populations.

Summary: The study determined the geographic distribution of the Rocky Mountain wood tick in Alberta, Canada, finding that the ticks were most abundant in Dry Mixedgrass and Montane natural subregions and certain soil types, with higher presence in areas with normal winter precipitation. A logistic regression model was developed to predict tick presence and the associated risk of tick-borne diseases in the province.
