dc.descriptionThe tick Amblyomma sculptum is a vector capable of harboring microorganisms, such as the pathogenic bacterium Rickettsia rickettsii, which is the causative agent of Rocky Mountain spotted fever (RMSF), known as Brazilian spotted fever (BSF) in Brazil (Labruna et al., 2014). It is therefore a species of great public health interest in this country (Andreotti et al., 2021) and, hence, controlling this parasite is extremely important. Among the bacteria present in ticks, Wolbachia may be also highlighted. This is an obligate intracellular endosymbiont bacterium that belongs to the Alphaproteobacteria group. Wolbachia is highly widespread in nature, such that it is present in more than 50% of terrestrial arthropod and filarial nematode species (Weinert et al., 2015; Bi et al., 2020).pt_BR
dc.description.abstractAs the main vector for the bacterium Rickettsia rickettsii in Brazil, the tick Amblyomma sculptum is a parasite of great public health importance in this country. Wolbachia is an endosymbiont bacterium highly widespread among invertebrates and because of its impact on its hosts' biology, form a powerful alternative for pests and disease control. The aim of this study was to investigate the occurrence of this bacterium in A. sculptum. For this, 187 adult ticks collected in two municipalities in the interior of the state of São Paulo, Brazil, were analyzed using molecular techniques and bioinformatics tools. A total of 15 ticks were positive for the presence of Wolbachia. Phylogenetic analysis on the 16S rRNA gene indicated that the Wolbachia DNA sequences obtained in this investigation belonged to different clades, probably in supergroups B and F. This was the first study to report the occurrence of Wolbachia in A. sculptum and it enriches knowledge about the susceptibility of ticks to this bacterium. Now that we know that Wolbachia can be found in A. sculptum, the objective for a next study must be to investigate Wolbachia's possible origin in this tick.pt_BR
