Phylogenetic analysis of the Francisella-like endosymbionts of Dermacentor ticks.
Bacterial endosymbionts with significant homology to Francisella tularensis (gamma-proteobacteria) have been described from at least five species of ticks in three different genera, including two North American Dermacentor species [D. andersoni Stiles and D. variabilis (Say)]. The evolutionary relationships among the Francisella-like endosymbionts (FLE) from different hosts and between FLE and ...
متن کاملTicks (Acari: Ixodidae) infesting camels (Camelus dromedarius) in Northern Sudan.
Monthly total body tick collections from 13-20 camels were conducted for 2 consecutive years (2000-2001) in Northern Sudan. Tick populations were correlated with locality, season, predeliction site, sex and coat colour. Hyalomma dromedarii was found to be the predominant (89%) tick species infesting the camels. Other tick species found in very low numbers were Hyalomma impeltatum (7.7%), Hyalom...
متن کاملAssessing Genetic Diversity of Shishi Date Palm Cultivars in Saudi Arabia and Qatar Using Microsatellite Markers
In this study fourteen microsatellite primer pairs were used to study the genetic diversity of Shishi Date palm in Qatar. A total of 32 date palm (15 Shishi cultivar, 10 Khalas and seven male date palms) were collected from Qatar and 5 Shihi cultivars were collected from Saudi Arabia for comparison. The Shishi set collected from Qatar was selected from different regions to represent the gene...
متن کاملDiscrimination between Francisella tularensis and Francisella-like endosymbionts when screening ticks by PCR.
The presence of Francisella-like endosymbionts in tick species known to transmit tularemia poses a potential diagnostic problem for laboratories that screen tick samples by PCR for Francisella tularensis. Tick samples initially considered positive for F. tularensis based on standard 16S rRNA gene PCR were found to be positive only for Francisella-like endosymbionts using a multitarget F. tulare...
متن کاملMultiple Acquisitions of Pathogen-Derived Francisella Endosymbionts in Soft Ticks
Bacterial endosymbionts of ticks are of interest due to their close evolutionary relationships with tick-vectored pathogens. For instance, whereas many ticks contain Francisella-like endosymbionts (FLEs), others transmit the mammalian pathogen Francisella tularensis. We recently sequenced the genome of an FLE present in the hard tick Amblyomma maculatum (FLE-Am) and showed that it likely evolve...
