Reptile-associated Borrelia spp. In Amblyomma ticks, Thailand

Molecular characterization of Amblyomma geoemydae using CO1 mitochondrial gene to validate phenotypic taxonomical evaluation

“…Studies were reported on the presence of Rickettsia, Ehrlichia, and Borrelia spp. from A. geoemydae via the analysis of housekeeping genes (gltA, ompA, ompB, sca4, 16SrRNA, flaB, glpQ, and groEL) for the experimental purpose the tick species was vindicated only via conventional morphology (Kaenkan et al 2020 ). Prevalence and molecular characterization of Ixodid ticks provide directions to the research area as well as species diversity, vector competence, microbial specificity on tick vectors, and also advanced preventive strategies and vaccine development.…”

“…Moreover, a comparable study was conducted in Malaysia (Che Lah et al 2022 ). Earlier scientific studies had a limited knack for recognizing A. geoemydae species based on nucleotide sequence (Kaenkan et al 2020 ). In earlier research, housekeeping gene analysis revealed the presence of Rickettsia , Ehrlichia , and Borrelia spp.…”

New host records of the reptile tick Amblyomma helvolum Koch (Ixodida: Ixodidae: Amblyomminae) in Taiwan

“…Amblyomma helvolum is a polyxenous bont tick primarily associated with squamates, particularly snakes, skinks, and varanid lizards. Many reptile species have been reported as hosts of A. helvolum , including representatives of the genera Boiga (Mao et al 2019), Bungarus (Ghosh et al 2021), Carlia (Oda et al 2022), Coelognathus (Sharif 1928; Audy et al 1960; Tanskul et al 1973; Oda et al 2022), Dasia (Auffenberg 1988), Dendrelaphis (Keirans 1984), Elaphe (Chao et al 2013), Eryx (Ghosh et al 2021), Eutropis (Krijgsman & Ponto 1931; Kohls 1950; Audy et al 1960; Kho et al 2019), Fowlea (Sumrandee et al 2014a, b; Sumrandee et al 2015; Kaenkan et al 2020), Gonocephalus (Auffenberg 1988), Gonyosoma (Keirans 1984), Hydrosaurus (Kohls 1950), Lycodon (Tabug & Necesito 2021), Malayopython (Neumann 1901; Schulze 1933; Kohls 1950; Audy et al 1960; Hoogstraal et al 1968; Tansku et al 1983; Kim 2020), Naja (Anastos 1950; Kohls 1957; Audy et al 1960; Kho et al 2015; Ghosh et al 2021), Ophiophagus (Warburton 1926), Otosaurus (Auffenberg 1988), Ptyas (Audy et al 1960; Lazell et al 1991; Sumrandee et al 2014a, b; Sumrandee et al 2015; Kaenkan et al 2020), Python (Sumrandee et al 2014a,b; Sumrandee et al 2015; Ghosh et al 2021), Rhabdophis (Audy et al 1960), Tropidophorus (Auffenberg 1988), Varanus (Neumann 1910; Sharif 1928; Schulze 1933; Kohls 1950; Audy et al 1960; Parrish 1971; Tanskul et al 1983; Keirans 1984; Auffenberg 1988; King & Green 1999; Pianka et al 2004; Kaenkan et al 2020), and Xenochropis (Audy et al 1960) . In addition, A. helvolum has been reported from the freshwater turtle genus Heosemys (family Geoemydidae) (<...…”

Host associations of the Asian monitor lizard tick Amblyomma varanense (Supino, 1897) (Ixodida: Ixodidae), with a new host record from the Philippines

“…In recent years, molecular analyses have detected several associated microbiota in A. varanense across its geographic range, including representatives of the families Borreliaceae (Spirochaetia: Spirochaetales), Francisellaceae (Gammaproteobacteria: Thiotrichales), and Rickettsiaceae (Alphaproteobacteria: Ricketssiales). Thus, Trinachartvanit et al (2016) reported a novel Borrelia species in A. varanense parasitizing Malayopython reticulatus (reticulated python) from Thailand, while Kaenkan et al (2020) detected Borrelia species in A. varanense associated with P. bivittatus (Burmese python), also from Thailand. Additionally, two novel Borrelia species belonging to the "reptile group borreliae" have been isolated from A. varanense parasitizing V. salvator from Indonesia (Supriyono et al 2019).…”
