“…In addition, a new potential host for H. longicornis , a Peromyscus sp., was documented in this study, and further investigations are needed to determine if this was an aberrant finding or if H. longicornis will feed on small rodents under certain circumstances. Finally, our molecular surveillance for pathogens infecting host-seeking H. longicornis reveals greater diversity of pathogens than previously recognized (Tufts et al, 2020b). While the role of the Hepatozoon sp.…”

“…Another study tested host-seeking ticks in Virginia and detected an exotic cattle pathogen, Theileria orientalis Ikeda strain (Thompson et al, 2020b). Finally, a study from New York using a shotgun sequencing approach failed to detect any bacterial or viral pathogens from H. longicornis (Tufts et al, 2020b). However, within its established range outside of the United States, H. longicornis is associated with numerous pathogens of both human and veterinary concern including Anaplasma , Theileria , Babesia , and spotted fever group Rickettsia spp.…”

Understanding the abiotic and biotic variables affecting tick populations is essential for studying the biology and health risks associated with vector species. We conducted a study on the phenology of exotic Haemaphysalis longicornis (Asian longhorned tick) at a site in Albemarle County, Virginia. We assessed the importance of available wildlife hosts, habitats, and microclimate variables such as temperature, relative humidity, and wind speed on this exotic tick’s presence and abundance. In addition, we determined the prevalence of selected tick-borne pathogens potentially transmitted by H. longicornis. We determined that the seasonal activity of H. longicornis was slightly different from previous studies in the northeastern United States. We observed nymphal ticks persist year-round but were most active in the spring, followed by a peak in adult activity in the summer and larval activity in the fall seasons. We also observed a lower probability of detecting H. longicornis in field habitats and the summer months. In addition, we detected H. longicornis on several wildlife hosts, including coyote (Canis latrans), eastern cottontail (Sylvilagus floridanus), raccoon (Procyon lotor), Virginia opossum (Didelphis virginiana), white-tailed deer (Odocoileus virginianus), woodchuck (Marmota monax), and a Peromyscus sp. This is the first detection of this tick on a rodent host important to the epidemiology of tick-borne pathogens of humans and animals. Finally, we continued to detect the exotic piroplasm parasite, Theileria orientalis Ikeda, in H. longicornis as well as other pathogens, including Rickettsia felis, Anaplasma phagocytophilum (AP-1), and a Hepatozoon sp. previously characterized in Amblyomma americanum. These represent some of the first detections of arthropod-borne pathogens native to the United States in host-seeking H. longicornis. These data increase our understanding of H. longicornis biology in the United States and provide valuable information into the future health risks associated with this tick and pathogens.

“…The ability of this species to reproduce parthenogenetically and the large population of white-tailed deer, a preferred host of H. longicornis [ 14 , 27 , 28 ], may facilitate the spread of this invasive tick on Block Island. Very few pathogens have been recovered from H. longicornis in some invaded regions of the USA [ 29 ], and their ability to vector native pathogens is still under investigation [ 11 , 12 ].…”

Background Invasive arthropod vectors and the range expansions of native vectors can lead to public and veterinary health concerns, as these vectors may introduce novel pathogens or spread endemic pathogens to new locations. Recent tick invasions and range expansion in the USA has been attributed to climate and land use change, an increase in global travel, and importations of exotic animals. Methods A 10-year surveillance study was conducted on Block Island, Rhode Island, from 2010 to 2020 including sampling ticks from small mammal and avian hosts. Results We report the discovery and establishment of the red sheep tick (Haemaphysalis punctata) for the first time in the western hemisphere and in the US. This invasive species was first collected in 2010 on Block Island, was collected continuously throughout the study, and was collected from an avian host. We document the first report of the invasive Asian longhorned tick (Haemaphysalis longicornis) in the state of Rhode Island, first observed at our sites in 2018. Finally, we present data on the range expansion and establishment of two native tick species, the lone star tick and the rabbit tick, on Block Island. Conclusion This study emphasized the importance of long-term surveillance to detect changes in tick host communities, including invasive and expanding native vectors of potential significance to humans and wildlife.

“…Only a couple of studies have observed the presence of reads belonging to this genus in tick samples. One is a metagenomic analysis of the pathobiome of Haemaphysalis longicornis (adults, nymphs and larvae) collected on Staten Island in the United States [ 96 ], and the other is a pyrosequencing analysis of the microbiota of Hyalomma [ 97 ]. This is of interest since several species are known to be pathogenic to humans [ 98 ].…”

Exploring the Individual Bacterial Microbiota of Questing Ixodes ricinus Nymphs

et al. 2021

Ixodes ricinus is the most common hard tick species in Europe and an important vector of pathogens of human and animal health concerns. The rise of high-throughput sequencing has facilitated the identification of many tick-borne pathogens and, more globally, of various microbiota members depending on the scale of concern. In this study, we aimed to assess the bacterial diversity of individual I. ricinus questing nymphs collected in France using high-throughput 16S gene metabarcoding. From 180 dragging-collected nymphs, we identified more than 700 bacterial genera, of which about 20 are abundantly represented (>1% of total reads). Together with 136 other genera assigned, they constitute a core internal microbiota in this study. We also identified 20 individuals carrying Borreliella. The most abundant species is B. afzelii, known to be one of the bacteria responsible for Lyme disease in Europe. Co-detection of up to four Borreliella genospecies within the same individual has also been retrieved. The detection and co-detection rate of Borreliella in I. ricinus nymphs is high and raises the question of interactions between these bacteria and the communities constituting the internal microbiota.
