Epidemics of vector-borne pathogens have risen dramatically in recent years, as we have witnessed the introduction of Zika along with West Nile viruses inside U.S., Crimean-Congo hemorrhagic fever in Southwestern Europe, along with the continuous emergence of Lyme disease throughout the Northeast of the U.S. along with central Europe. Ticks are the most important vectors for infectious diseases inside Northern Hemisphere along with second worldwide, after mosquitoes. Thus, the introduction of an invasive species in a completely new habitat is usually worrying.
In Asia along with Australia, the longhorned tick is usually known to transmit diseases to livestock including protozoans Theileria orientalis along with Babesia spp., which cause anemia, lethargy along with occasionally abortions. In addition, uninfected longhorned ticks can endanger the animal’s health since in large numbers their constant blood-sucking causes anemia, loss of productivity, along with occasionally the death of calves.
In addition, H. longicornis has been associated with human pathogens including Anaplasma phagocytophilum, spotted fever Rickettsia, along with Borrelia spp. These ticks also carry viruses, including Powassan virus, which features a high fatality rate of up to 10 percent. Of those who survive, 50 percent experience permanent brain injury along with SFTS virus (severe fever with thrombocytopenia syndrome), which causes encephalitis along with severe fever with thrombocytopenia, a shortage of blood clotting platelets. Although tick-borne pathogens are generally tick specific, the fact which which tick has been associated with Anaplasma phagocytophilum along with Powassan virus, which are present in completely new Jersey, raises the question of whether they can acquire along with transmit these diseases locally.
So far, there are no documented instances of H. longicornis transmitting human pathogens, along with there is usually no evidence so far which they represent a public health risk.
