Haemaphysalis longicornis (Neumann, 1901) (Acari: Ixodidae), the Asian longhorned tick, is an invasive tick species present in USA since at least 2017 and has been detected one-third of Virginia counties. While this associated with transmission multiple pathogens its native geographical range eastern Asia, little known about ability to acquire transmit USA, specifically those that are transmissible humans, although from animal health perspective, it already shown vector Theileria orientalis...
Tick-borne pathogen infections are an increasing occurrence globally, yet many aspects of maintenance and host-tick interactions remain poorly understood. Here we consider the potential role eastern cottontails (Sylvilagus floridanus) in enzootic cycles tick-borne pathogens medical importance Virginia. Over a 3-year period, ticks blood were collected from rabbits acquired through passive surveillance 21 counties Seven hundred seventy 90 121 examined this study. Tick species included...
Abstract Established tick control strategies often involve methods that can be damaging to existing environmental conditions or natural host ecology. To find more environmentally friendly methods, biological controls, like predators of ticks, have been suggested. There are but most generalists and not expected populations. Helmeted guinea fowl (Numida meleagris (L.) (Galliformes: Numididae)) suggested controls therefore, tick-borne pathogens, their potential role as hosts for ticks...
Abstract Over the past decade, Haemaphysalis longicornis, Asian longhorned tick, has undergone a geographic range expansion in United States, from its historical east Asia. This tick been characterized by frequent parasitism of livestock, an ability to reproduce through parthenogenesis, and transmit variety vector-borne pathogens wildlife, human hosts native range. Thus far 17 states have reported H. longicornis populations, including 38 counties Virginia. These numbers come presence-absence...
Ticks are known vectors of several viral, bacterial, and protozoal pathogens that cause disease in both humans animals. While pathogen prevalence has been studied extensively other portions the United States, surveillance studies within tick populations central Appalachian region Virginia is almost nonexistent. Two prominent species this Ixodes scapularis (the blacklegged tick) Amblyomma americanum lone star tick). In study, we collected ticks biweekly from three habitat types (forest,...
Abstract Ticks and tick-borne diseases are an immense public health burden in New York State (NYS), United States. Tick species associated pathogens expanding into new areas, shifting threats to human, animal across the state. For example, invasive tick, Haemaphysalis longicornis Neumann (Acari: Ixodidae), was first detected States 2017 has since been identified 17 states, including NYS. In addition, Amblyomma americanum (L.) Ixodidae) is a native tick thought be reestablishing historical...
Here we report the first detection and confirmation of Powassan virus (POWV) (family: Flaviridae) in Ixodes scapularis ticks collected from Appalachian Virginia. were vegetation across field sites eight counties western Virginia June 2019 to April 2021. From these collections, one nymph adult male I. determined be positive for POWV using real-time RT-PCR Sanger sequencing. Both Floyd county, VA, at residential sites; 2020 The presence its natural tick vector is crucial knowledge beginning...
