Abstract

The aim of this study was to assess the presence of Rickettsia in soft ticks (Acari: Argasidae) collected from insectivorous bats (Chiroptera) in Santa Fe province, Argentina. First, a subset of ticks were mounted in Hoyer's medium to be determined by morphological characters and then confirmed by sequencing the mitochondrial 16S rRNA gene. Also ticks were processed by PCR assays using primers CS-78 and CS-323, which amplify a fragment of the Rickettsia spp. gltA gene. Positive ticks were subjected to a second PCR round with primers Rr190.70p and Rr190.701n of the spotted fever group rickettsiae ompA gene. A phylogenetic analysis was performed with Maximum-likelihood method, and the best fitting substitution models were determined with the Akaike Information Criterion. Five bats of the species Eptesicus diminutus Osgood, 1915, Eptesicus furinalis (d'Orbigny and Gervais, 1847), Eptesicus spp. (Vespertilionidae), and Molossops temminckii Burmeister, 1854 (Molossidae) were parasitized with Ornithodoros hasei (Schulze, 1935) larvae. One E. diminutus ticks' tested positive to " Candidatus Rickettsia wissemanii", a spotted fever group rickettsiae. The association O. hasei –" Ca. R. wissemanii" detected in this study represents the first evidence of a Rickettsia in Ornithodoros ticks in Argentina and the third report of this association in America. Also, this finding constitutes the first record of " Ca. R. wissemanii" in Argentina. Finally, we found for the first time the insectivorous bats E. diminutus and E. furinalis parasitized with O. hasei larvae. These findings add two new hosts and a new location, the southernmost recorded to date, for O. hasei. [ABSTRACT FROM AUTHOR]

Abstract

Six larvae of the genus Ornithodoros were collected in Rio Lavayén, approximately 1km north of Santa Rita, San Pedro Department (24º 28´S, 64º 48´W), Jujuy Province, Argentina, on three species of bats: Molossops temminckii (Burmeister, 1854) (Molossidae), Myotis albescens (E. Geoffroy, 1806) (Vespertilionidae) and Ornithodoros were collected in Rio Lavayén, approximately 1km north of Santa Rita, San Pedro Department (24º 28´S, 64º 48´W), Jujuy Province, Argentina, on three species of bats: Molossops temminckii (Burmeister, 1854) (Molossidae), Myotis albescens (E. Geoffroy, 1806) (Vespertilionidae) and Molossops temminckii (Burmeister, 1854) (Molossidae), Myotis albescens (E. Geoffroy, 1806) (Vespertilionidae) and (Burmeister, 1854) (Molossidae), Myotis albescens (E. Geoffroy, 1806) (Vespertilionidae) and Histiotus laephotis Thomas, 1916 (Vespertilionidae). All six larvae were identified as belonging to the Thomas, 1916 (Vespertilionidae). All six larvae were identified as belonging to the Ornithodoros hasei species group, whose members are common parasites of bats throughout the Neotropical Zoogeographic Region. This is the first record of the O. hasei species group in Argentina, and M. temminckii species group, whose members are common parasites of bats throughout the Neotropical Zoogeographic Region. This is the first record of the O. hasei species group in Argentina, and M. temminckii O. hasei species group in Argentina, and M. temminckii and H. laephotis are new hosts for this tick. Studies of the morphology, genetics and ecology of O. hasei across its vast range will be necessary in order to determine whether sibling species are present.
