Summary: The present study aimed to investigate the dominant tick populations and identify the pathogenic agents of anaplasmosis in ticks from Gyeongsang, Republic of Korea. A total of 3825 questing ticks were collected from 12 sites near animal farms in Gyeongsang. Molecular genomic analysis was conducted to detect Anaplasma genes in the collected ticks. The most prevalent tick species were Haemaphysalis longicornis, Haemaphysalis sp., Haemaphysalis flava, Ixodes nipponensis, and Amblyomma testudinarium in that order. The infection rates of Anaplasma species varied, with A. phagocytophilum being the most common. The findings of this study provide valuable information for future research on tick-borne diseases.

Most ticks belonged to the genus Ixodes, with Ixodes ricinus being the most common. A subset of 500 ticks collected from at-risk populations showed an overall infection prevalence of 22.8%, with Rickettsia spp., Borrelia spp., and Anaplasma spp. being the main pathogens detected.

Summary: This study molecularly confirmed the presence of Anaplasma marginale and A. phagocytophilum in ticks of the Rhipicephalus genus, suggesting their importance in transmitting potential zoonotic infections. Further investigations are needed to understand the public health implications and determine if these tick species can transmit these zoonotic bacteria to humans and animals. It is important to monitor the prevalence of these pathogens in Sardinia due to the increasing impact of tick-borne Anaplasma pathogens on human health.

Summary: The rapid growth of the horse industry in South Korea has led to an increased exposure to ticks and their associated pathogens. A study collected 9220 ticks from horses and pastures, identifying two tick species, with two zoonotic pathogens (Anaplasma phagocytophilum and Borrelia spp.) detected in a small percentage of tick pools. Phylogenetic analysis showed relationships to strains from various countries, highlighting the importance of understanding disease risks and developing prevention strategies.

Summary: In this comprehensive review study, the challenge posed by ticks and tick-borne diseases (TBDs) with growing incidence affecting global human and animal health was addressed. Data and perspectives from different countries and regions were collected to update the current situation with ticks and TBDs and highlight the existing information bias and gaps perceived by society. The study emphasizes the importance of multidisciplinary and international collaborations in advancing surveillance, communication, and proposed future directions to address these challenges.

Summary: The study aimed to screen and genetically identify tick-borne pathogens in dogs and associated ticks in Egypt. The prevalence of TBPs in dogs was 23.56%, with Anaplasma, Ehrlichia, and Babesia being the most common. The molecular prevalence rate of TBPs was 25.81% in dog blood samples and 29.17% in ticks, with various species of TBPs detected, including Hepatozoon canis and Anaplasma marginale being reported for the first time in Egypt.

Summary: Ticks and tick-borne pathogens (TTBPs) pose a serious economic threat to ruminant production worldwide. Investigations focused on goats remain limited compared to those for pathogens infecting cattle. This study examined TTBPs from 6 provinces in Thailand using PCR-based surveys and phylogenetic analysis. The results showed a low infection rate of Anaplasma spp. and piroplasmids in goats, and Anaplasma bovis, Anaplasma marginale, and Anaplasma ovis were detected for the first time in goats in Thailand. It was also found that TTBP infections were linked to the rainy season.

Summary: This study in north-eastern Poland focused on ticks removed from wild cervids and boars to examine the presence of Borrelia species, Rickettsia species, and Anaplasma phagocytophilum. The results showed that almost 40% of the collected ticks were infected, with A. phagocytophilum and Rickettsia species being the most prevalent. Different species of Borrelia were also identified, with Borrelia species only found in ticks collected from cervids. The study revealed significant differences in pathogen affinity to tick species, with Borrelia species and A. phagocytophilum more commonly detected in Ixodes ricinus than in Dermacentor reticulatus.

Summary: Ticks in Africa remain a major obstacle in the livestock industry due to tick-borne pathogens. This study conducted a systematic review and meta-analysis to examine the distribution and prevalence of these pathogens in African ticks. The highest prevalence was found for Rickettsia spp., R. africae, R. conorii, A. marginale, E. ruminantium, and E. canis. The prevalence of C. burnetii was low, but higher for Coxiella spp. and Coxiella-like endosymbionts. The study also identified the effect of tick genera, tick species, country, and other variables on the epidemiology of these pathogens in ticks.

Summary: The geographic distributions of medically important ticks and tick-borne pathogens in the United States are expanding, leading to an increase in the burden of tick-borne diseases and a growing risk of coinfections. The study found that Borrelia burgdorferi s.s. was the most prevalent and widespread pathogen, and co-infections with this pathogen and others were most common in the Northeast region.

Summary: The Centers for Disease Control and Prevention have developed a bioinformatics pipeline, called MPAS, that can enhance the detection of human pathogens in ticks. This pipeline is portable and reproducible, with the ability to modify input parameters, assay primer, and reference sequences. It automates the analysis process, reducing the time needed for downstream analysis. The validation of the MPAS pipeline showed comparable results to previous analyses and improved sequencing resolution for co-infected samples.

Summary: Lyme disease, the most common vector-borne disease in the United States, is primarily caused by the bacterium Borrelia burgdorferi s.s. Research has focused on reducing tick densities to mitigate the risk, with white-tailed deer management considered a potential method. However, the impact of deer management on the density of infected ticks and prevalence of infection is unclear.

Summary: The majority of vector-borne diseases in the United States are caused by blacklegged ticks. The geographic range of these ticks and their associated human pathogens has expanded, putting more communities at risk for tick-borne infections. A national tick surveillance program was initiated by the CDC to monitor changes in tick distribution and the prevalence of human pathogens. The study found that the prevalence of pathogens was highest in the Northeast, Ohio Valley, and Upper Midwest regions where Lyme disease is commonly reported.
