Abstract
BackgroundSpecies of the genus Borrelia are causative agents of Lyme disease and relapsing fever. Lyme disease is the most commonly reported vector-borne disease in the northern hemisphere. However, in some parts of the world Lyme borreliosis and relapsing fever may be caused by novel Borrelia genotypes. Herein, we report the presence of a Borrelia sp. in an Amblyomma varanense collected from Python reticulatus.MethodsTicks were collected from snakes, identified to species level and examined by PCR for the presence of Borrelia spp. flaB and 16S rRNA genes. Phylogenetic trees were constructed using the neighbour-joining method.ResultsThree A. varanense ticks collected from P. reticulatus were positive for a unique Borrelia sp., which was phylogenetically divergent from both Lyme disease- and relapsing fever-associated Borrelia spp.ConclusionThe results of this study suggest for the first time that there is a Borrelia sp. in A. varanense tick in the snake P. reticulatus that might be novel.
Highlights
Species of the genus Borrelia are causative agents of Lyme disease and relapsing fever
Tick infestation in snakes occurs worldwide and involves the following species: Amblyomma gervaisi in the northern region of western Ghats in India [1], Rhipicephalus sanguineus in Malaysia [2], Amblyomma varanense and Amblyomma helvolum in Thailand [3, 4] and Amblyomma hydrosauri in Australia [5]
The aim of this study was to determine the presence of Borrelia spp. within Amblyomma spp. ticks collected from five snake species
Summary
Species of the genus Borrelia are causative agents of Lyme disease and relapsing fever. In some parts of the world Lyme borreliosis and relapsing fever may be caused by novel Borrelia genotypes. We report the presence of a Borrelia sp. Tick infestation in snakes occurs worldwide and involves the following species: Amblyomma gervaisi in the northern region of western Ghats in India [1], Rhipicephalus sanguineus (sensu lato) in Malaysia [2], Amblyomma varanense and Amblyomma helvolum in Thailand [3, 4] and Amblyomma hydrosauri in Australia [5]. Hirunkanokpun et al [6] detected several bacterial species in the national parks of Thailand, but no Borrelia spp. were found. The aim of this study was to determine the presence of Borrelia spp. within Amblyomma spp. ticks collected from five snake species. Phylogenetic analyses of Borrelia spp. are presented
