| molecular evidence of potential novel spotted fever group rickettsiae, anaplasma and ehrlichia species in amblyomma ticks parasitizing wild snakes. | amblyomma ticks parasitize a wide range of animals in tropical regions. this study describes the identification of amblyomma ticks from wild snakes in malaysia and the detection of potential human pathogens such as rickettsia, anaplasma, ehrlichia and bartonellae in the ticks. | 2015 | 25889376 |
| hepatozoon and theileria species detected in ticks collected from mammals and snakes in thailand. | we report the detection of hepatozoon and theileria in 103 ticks from mammals and snakes in thailand. by using a genus-specific 18s rrna pcr, hepatozoon and theileria spp. were detected in 8% and 18%, respectively, of ticks (n=79) removed from mammals. of the ticks removed from snakes (n=24), 96% were infected with hepatozoon spp., but none were infected with theileria. phylogenetic analysis revealed that hepatozoon spp. detected from dermacentor astrosignatus and dermacentor auratus ticks from ... | 2015 | 25736475 |
| molecular detection of rickettsia species in amblyomma ticks collected from snakes in thailand. | some reptile ticks are potential vectors of pathogens such as spotted fever group (sfg) rickettsiae. here, we report for the first time in detail the molecular evidence, dna sequences and phylogenetic studies, for the presence of rickettsia spp. in amblyomma ticks (amblyomma helvolum and amblyomma varanense) from snakes in thailand. a total of 24 tick samples was collected from 4 snake species and identified. a phylogenetic analysis inferred from the partial sequences of the glta gene indicated ... | 2014 | 25027232 |
| rickettsia sp. closely related to rickettsia raoultii (rickettsiales: rickettsiaceae) in an amblyomma helvolum (acarina: ixodidae) tick from a varanus salvator (squamata: varanidae) in thailand. | an engorged female amblyomma helvolum koch tick was removed from an adult varanus salvator laurenti lizard during field collection in thailand. after using polymerase chain reaction to amplify three genes (16s rdna, glta, and ompa), we discovered the presence of a rickettsia sp. of the spotted fever group. phylogenetic analysis revealed that this rickettsia sp. is closely related to rickettsia raoultii mediannikov. therefore, we report herein for the first time the detection of a novel spotted f ... | 2013 | 23427674 |
| francisella-like endosymbiont in a tick collected from a chicken in southern thailand. | francisella is a genus of bacterial pathogens potentially lethal to humans. we report here for the first time a novel francisella-like endosymbiont discovered in a hard-tick (rhipicephalus sanguineus s.l.) obtained from a chicken (gallus domesticus) in thailand. the phylogenetic results indicate the 16s rdna sequences of this francisella bacterium form a unique clade with the francisella-like endosymbiont of the tick species, amblyomma varanense and amblyomma helvolum, that have previously been ... | 2016 | 27244963 |
| phylogenetic relationships of francisella-like endosymbionts detected in two species of amblyomma from snakes in thailand. | ticks are important vectors of several bacterial pathogens, including francisella. in this study, a total of 24 adult ticks (amblyomma varanense and amblyomma helvolum) collected from 4 species of snake from 3 provinces of thailand was screened for the presence of francisella-like endosymbionts (fles) by pcr. fles were detected in 46% (11/24) of all ticks examined. a phylogenetic analysis of the 16s rdna sequence indicated that the 11 distinct genotypes of fles amplified from a. varanense and a. ... | 2014 | 24446556 |
| first report of amblyomma helvolum (acari: ixodidae) from the taiwan stink snake, elaphe carinata (reptilia: colubridae), collected in southern taiwan. | a taiwan stink snake (elaphe carinata) was captured in shrubbery at a fruit farm in southern taiwan, and 3 female ticks (2 flat, one fully engorged) observed on this snake were collected and identified as amblyomma helvolum, the first record of this host association in mainland taiwan. the key morphological characters of female a. helvolum were photographed using a stereomicroscope. this first report of a. helvolum feeding on a reptilian host in taiwan includes the first color illustrations of a ... | 2013 | 23352173 |
