Summary: This study determined the occurrence of Rickettsia africae in Amblyomma hebraeum ticks infecting livestock in the North West Province of South Africa. It was found that Rickettsia africae was present in 48% of cattle, 40% of sheep, and 32% of goats. Although the animals did not exhibit clinical symptoms, Rickettsia africae is still recognized as having significant zoonotic potential.

Summary: This study surveyed ticks collected from animals in 23 different states in the eastern USA, with the primary goal of better characterizing the distribution and host associations of the exotic tick H. longicornis. New distribution data on tick species of veterinary or medical importance were also obtained.

Summary: Ticks secrete proteins in their saliva that modulate host inflammation, immune responses, haemostasis or may cause paralysis during feeding. RNA next generation sequencing technologies reveal complex dynamics of tick salivary glands, with different functional classes of proteins showing differential expression during feeding in both genders. The transcriptome data contributes to understanding salivary gland biology and blood feeding physiology of non-model organisms.

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: Ticks in Khao Yai National Park in Thailand were found to be infected with pathogenic bacteria at varying rates, with different genera showing distinct infection patterns. Co-infection was detected in female ticks, primarily between Rickettsia spp. and Anaplasmataceae. Ticks carrying the Coxiella-like endosymbiont were more likely to be infected with Ehrlichia spp. or Rickettsia spp. compared to those without, particularly for Ehrlichia spp. detection.

Summary: Records of accidental parasitism by ticks in humans are scarce in Brazil, mainly reported by researchers and professionals. A literature review was conducted including studies published from 1909 to 2022. The study identified nine species in the Argasidae family and 32 species in the Ixodidae family that have been reported biting humans in Brazilian biomes. The species with the highest number of parasitism records was Amblyomma sculptum. The Atlantic Forest was the most frequent biome where human parasitism occurred. Several species known for transmitting pathogens were also reported.

Summary: This article summarizes the common ticks infesting dogs and cats in North America, including their life histories, morphologies, and feeding behaviors. It also highlights the changes in geographic distribution and the risks of tick-borne diseases for pets. Understanding the natural history of ticks and the maintenance cycles responsible for infections is crucial in combating the health challenges posed by ticks.

Summary: This study investigated the effects of rapid cold hardening (RCH) on gene expression and metabolism during recovery from cold stress in the American dog tick. The results showed that after recovery from RCH, 1860 genes were differentially expressed in ticks, while only 99 genes responded during recovery from direct cold shock. The accumulation of certain metabolites corresponded to transcriptional shifts in the pathways associated with these molecules, suggesting congruent metabolome and transcriptome changes.

Summary: Ixodes ricinus is the most common tick species in Germany and large parts of Europe and poses a potential risk to players and visitors on football grounds. The study found that ticks are frequently found near football grounds, especially those close to forests or parks, and sometimes in high abundance. This highlights the importance of tick control measures in these areas to reduce the risk of tick-borne diseases.

Summary: This study investigated the presence and localization of alpha-gal-containing proteins in ticks and parasites, and found that the concentration of alpha-gal in Ascaris lumbricoides was higher than that in ticks. Additionally, the study showed that non-alpha-gal proteins from Ascaris lumbricoides were able to activate basophils in the presence of serum from individuals with alpha-gal syndrome, suggesting a potential role of Ascaris lumbricoides in alpha-gal sensitization and clinical reactivity.

Summary: This study investigated the diversity of ticks parasitizing birds in the Brazilian Atlantic Forest and examined the molecular detection of Rickettsia spp. in these ticks. The seasonal distribution of tick populations and their correlation with temperature were observed. About 25.44% of the evaluated tick samples tested positive for Rickettsia spp., showing high nucleotide identity with several Rickettsia species. The potential for tick dispersal by birds and the zoonotic potential of certain Rickettsia species are concerning in this widely-visited study area.

Summary: This study describes the presentation, clinical signs, parasitemia levels, laboratory findings and treatment of dogs infected with B. negevi. Treatment with imidocarb dipropionate was helpful for recovery from clinical disease but did not facilitate parasite elimination, and it is therefore recommended to treat canine B. negevi infection with the combination of atovaquone and azithromycin.

Summary: In many parts of the northern hemisphere, different species of deer, small mammals, and birds coexist and their composition can strongly influence the outbreak potential of tick-borne pathogens. This study investigates how the abundance and composition of vertebrate communities affect the basic reproduction number R0 of tick-borne pathogens, and shows that species composition plays a substantial role in the outbreak potential of tick-borne diseases.

Summary: Published data on tick-borne pathogens in camels worldwide have been collected, providing an overview of their global prevalence and species diversity. Evidence of natural infection of camels with certain tick-borne pathogens is limited, particularly because most of the camels were considered healthy at the time of sampling. More research is needed to understand the role of camels in maintaining and transmitting these pathogens.
