Chigger mites (Acari: Trombiculidae and Leeuwenhoekiidae) parasites of vertebrates: morphological studies and investigation of the presence of Rickettsia spp.

Abstract

Chigger mites are the common name of the larval stage of mites in the family Trombiculidae s. l. that parasitic vertebrates and during parasitism, can cause a skin reaction in the host, known as trombiculiasis. In Brazil, 69 species are known and in many of them are one only record for locality and the host. In Asia-Pacific region, some species of chiggers are vectors of tsutsugamushi, a human rickettsiosis, caused by the bacterium Orientia tsusugamushi. In addition, the presence of some pathogens (Borrelia, Coxiella, Hepatozoon and Rickettsia) has been detected in chigger mites in various parts of the world . For Brazil, Ricekttsia felis-like was detected in the Blankaartia sinnamaryi mite collected parasitizing bird, as well as Ricekttsia sp. was found in three chiggers species collected from rodents in São Paulo state. In the Neotropical region, chiggers are poorly studied and there are gaps in taxonomy, biodiversity and host association. National and international collections will be consulted and specimens preserved in tissue banks will be examined for pathogen detection testing and sequences generated will be deposited in gene banks. Considering the lack of knowledge of the distribution and species that occur in this country of continental dimensions, and that there are indications of the possibility of larvae to participate in the transmission of pathogens, the investigative analysis of Rickettsia in this group of mites in Brazil is relevant.
