Summary: Two 90-day studies confirmed the efficacy of two fluralaner formulations in eliminating H. longicornis ticks from cats. The treatments were found to be 100% effective on Day 2 and maintained an efficacy of >95% to 100% for 90 days. Fluralaner is therefore a preferred treatment for protecting cats against this invasive tick species.

Summary: This study used species distribution modeling (Maxent) to predict suitable habitat areas for the invasive Asian longhorned tick in northeast Tennessee, and identified increasing human risk in the future. It suggests utilizing species distribution models as an effective tool for surveillance and control strategies against the spread of the Asian longhorned tick.

Summary: The Asian longhorned tick, originally from eastern Asia and known to transmit diseases, has been recently found in the United States. A study of its seasonal activity patterns in New York revealed that it is capable of completing a generation within a year, matching patterns observed in other regions.

Summary: The Asian longhorned tick (Haemaphysalis longicornis) is an invasive tick species that has been detected in several counties in Virginia, USA. This study found that the Asian longhorned tick can carry the Bourbon virus, and there may be spillover of pathogens from native tick species.

Summary: Over the past decade, the Asian longhorned tick has expanded its geographic range in the United States, with populations reported in 17 states, including 38 counties in Virginia. This tick is known for its parasitism of livestock, ability to reproduce through parthenogenesis, and transmission of vector-borne pathogens. Our study found the presence of this tick in multiple habitat types in Virginia, with habitat type and climatic metrics being important indicators of tick presence and abundance.

Summary: The Asian longhorned tick, an invasive species originally from eastern Asia, has been reported in multiple states in the USA and is a known vector of diseases in livestock and humans. Recently, this tick was found in Greene County, Missouri for the first time, prompting concern over its potential spread in the state and county.

Summary: Since its discovery in 2017, the Asian longhorned tick has rapidly invaded and expanded in multiple surveying sites on Long Island, in contrast to previous surveys conducted in 2018. The relative abundance of the Asian longhorned tick is similar to that of the lone star tick on Long Island. Its expansion pattern differs from that of native tick species in the area. The implications of the Asian longhorned tick transmitting tick-borne pathogens remain unknown.

Summary: In this study, the protein regulation mechanism of low-temperature tolerance in Haemaphysalis longicornis was investigated. The results showed that maintaining cell homeostasis, cell viability, and enhancing cell tolerance were crucial for the ticks to survive under low temperatures. Furthermore, arylamine N-acetyltransferase, inositol polyphosphate multikinase, and dual-specificity phosphatase were identified as potential key proteins in low-temperature tolerance.

Summary: This study aimed to evaluate the effectiveness of a recombinant Hemalin (rHlHemalin) vaccine as an anti-tick vaccine against H. longicornis in rabbits and to find a potential candidate for tick control. The results showed that rHlHemalin protein stimulated cytokine production in mouse splenocytes and vaccination extended the reproductive cycle of H. longicornis.

Summary: Theileria orientalis Ikeda genotype, a parasite causing economic challenges in cattle in Asia, New Zealand, and Australia, has been identified in Alabama, USA. The study found that infected cattle showed a high pathogen burden and the infection was persistent even in seemingly healthy cattle. Further investigation and surveillance of Theileria orientalis Ikeda and Haemaphysalis longicornis ticks in Alabama and other states, as well as evaluating the pathogenicity in cattle, are necessary.

Summary: The Asian longhorned tick, Haemaphysalis longicornis Neumann, was collected in Madison County, Kentucky, United States as part of a collaborative-tick surveillance project. This is the first collection of this invasive tick, with ancillary data on habitat and landscape features derived from the USDA Forest Service, Forest Inventory and Analysis program.

Summary: This study analyzed the phosphorylated proteins in the saliva of Haemaphysalis longicornis ticks and identified 262 phosphorylated tick saliva proteins. Functional annotation and enrichment analysis revealed that these proteins are involved in cellular and metabolic processes, particularly in transport-oriented processes. Knockdown of certain proteins resulted in various effects on tick feeding and reproduction. These findings demonstrate the importance of salivary phosphoproteins in facilitating tick feeding.

Summary: In this study, the molecular mechanisms of transovarial transmission of the Babesia parasite in ticks were investigated. The expression profiles of key molecules involved in tick oogenesis were analyzed, revealing the impact of Babesia infection on yolk protein precursor synthesis and uptake. The accumulation of HIVg-2 was found to be associated with Babesia infection and transmission in ticks. These findings provide important insights into the transovarial transmission mechanisms of pathogens in tick vectors.

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.
