BackgroundCoxiella bacteria were identified from various tick species across the world. Q fever is a zoonotic disease caused by the bacteria Coxiella burnetii that most commonly infects a variety of mammals. Non-mammalian hosts, such as birds, have also been reported to be infected with the pathogenic form of “Candidatus Coxiella avium”. This research increases the list of tick species that have been found with Coxiella-like bacteria in Thailand.MethodsA total of 69 ticks were collected from 27… Expand

Coxiellaceae in Ticks from Human, Domestic and Wild Hosts from Sardinia, Italy: High Diversity of Coxiella-like Endosymbionts
The molecular detection of a high diversity of Coxiella- like bacteria in Sardinian ticks is reported and the presence of C. burnetii in tick species previously identified in the island is confirmed. Expand

Ticks are dangerous ectoparasites of humans and animals, as they are important disease vectors and serve as hosts for various microorganisms (including a variety of pathogenic microorganisms).Expand
Partial DnaK protein expression from Coxiella-like endosymbiont of Rhipicephalus annulatus tick
The partial DnaK protein of CLE from R. annulatus could be considered a vaccine candidate and immunogenic marker with future prospects and some predicted HLA-A and B alleles of the MHC-I and Hla-DR alleles belonging to M HC-II were similar to T-cell responses to C. burnetii in Q fever patients.

Current approaches for the detection of Coxiella burnetii infection in humans and animals.
The disease has remained largely under-reported, underdiagnosed and as a masked zoonosis; and therefore, needs to be explored through well-planned scientific studies for knowing its true status and likely it impact in humans and animals by employing state-of-the-art diagnostics. Expand
General Microbiota of the Soft Tick Ornithodoros turicata Parasitizing the Bolson Tortoise (Gopherus flavomarginatus) in the Mapimi Biosphere Reserve, Mexico
The general bacterial microbiota of the soft tick Ornithodoros turicata found on Bolson tortoises, considered the largest terrestrial reptile in North America distributed throughout the Chihuahuan Desert since the late Pleistocene, was established and the presence of potentially pathogenic species for this tortoise, other animals, and humans was documented.

Lists of names of prokaryotic Candidatus taxa.

Coxiella Detection in Ticks from Wildlife and Livestock in Malaysia
The presence of C. burnetii is suggested in two samples, each from D. steini and H. hystricis, adding to the growing evidence of the association between Coxiella-like bacteria and ticks across species and geographical boundaries. Expand
Diversity and global distribution of the Coxiella intracellular bacterium in seabird ticks.
The potential epidemiological significance of the presence of Coxiella in seabird ticks is discussed, and it is suggested that these organisms may not be pathogenic forms, but rather behave as endosymbionts engaged in intricate interactions with their tick hosts. Expand
Coxiella symbiont in the tick Ornithodoros rostratus (Acari: Argasidae).
Results suggest a very long period of coevolution between ticks and Coxiella symbionts and indicates that the original infection may have occurred in an ancestor common to the 2 main tick families, Argasidae and Ixodidae. Expand
Endosymbionts of ticks and their relationship to Wolbachia spp. and tick-borne pathogens of humans and animals
The presence, internal distribution, and phylogenetic position of endosymbiotic bacteria from four species of specific-pathogen-free ticks were studied and it was indicated that the symbionts of these four tick species were not related to the Wolbachia species found in insects. Expand

The Recent Evolution of a Maternally-Inherited Endosymbiont of Ticks Led to the Emergence of the Q Fever Pathogen, Coxiella burnetii
This corpus of data demonstrates that C. burnetii recently evolved from an inherited symbiont of ticks which succeeded in infecting vertebrate cells, likely by the acquisition of novel virulence factors. Expand
Detection of Rickettsia and a Novel Haemaphysalis shimoga Symbiont Bacterium in Ticks in Thailand
PCR analysis revealed Rickettsia bacteria in these two Haemaphysalis species present at the Khao Yai National Park in Thailand and investigated the presence of rickettsia in these ticks, the first time such presence has been reported in Thailand. Expand
Phylogenetic studies of bacteria (Rickettsia, Coxiella, and Anaplasma) in Amblyomma and Dermacentor ticks in Thailand and their co-infection.
Bacterial co-infections in Dermacentor and Amblyomma ticks may cause co-transmission of some tick-borne microorganisms (pathogen and endosymbiont, whether enhance or reduce) in humans and animals and they could affect medical and veterinary health. Expand

The derived phylogeny failed to support a monophyletic relationship among members of Ornithodorinae and supported placement of Argasinae as basal to the Ixodidae, suggesting that hard ticks may have originated from an Argas-like ancestor, and supports earlier suggestions thathard ticks did not evolve until the late Cretaceous.
