ABSTRACT
In Brazil, recent studies have reported viruses detected in ticks with pathogenic potential in vertebrate hosts. Ticks of the species Rhipicephalus microplus collected from bovines in a savannah area were tested by RT-PCR for the presence of RNA targetting a segment of NS3-like protein gene of Mogiana tick virus, a member of the recently-described Jingmenvirus group. Amplification with size similar to the expected was observed with 25% (7/28) RNA samples of ticks that were collected from 39% (7/18) of the bovines. Nucleotide sequence analysis of three PCR products revealed divergence that varied from 3.3 to 5.0% in a single farm. Although Jingmen tick virus, another member belonging to the Jingmenvirus group, has been detected in human patients with Crimean-Congo hemorrhagic fever in Kosovo, whether or not MGTV causes disease in cattle and other animals remains to be investigated.
