| rickettsia hoogstraalii sp. nov., isolated from hard- and soft-bodied ticks. | a novel spotted fever group rickettsia was found in haemaphysalis sulcata ticks collected from sheep and goats in croatia in 2006. at the same time, a genetically identical organism was co-isolated with the embryonic cell line cce3 obtained from the soft tick carios capensis in georgia, usa. in this study, further phenotypic and genotypic characteristics of the novel rickettsial strain present in h. sulcata ticks were investigated. based on the cultivation of bacteria in mosquito and vero cell c ... | 2010 | 19666817 |
| spotted fever group rickettsiae in ticks in cyprus. | in two surveys conducted from march 1999 to march 2001 and from january 2004 to december 2006, a total of 3,950 ticks (belonging to ten different species) were collected from seven domestic and wild animals (goat, sheep, cattle, dog, fox, hare, and mouflon) from different localities throughout cyprus. in order to establish their infection rate with spotted fever rickettsiae (sfg), ticks were pooled and tested by polymerase chain reaction targeting glta and ompa genes, followed by sequencing anal ... | 2011 | 21833539 |
| genome sequence of rickettsia hoogstraalii, a geographically widely distributed tick-associated bacterium. | rickettsia hoogstraalii is a tick-associated member of the spotted fever group rickettsiae that is geographically widely distributed. we report here the draft genome of r. hoogstraalii strain croatica(t) (=dsm 22243 = utmb 00003), which was isolated from haemaphysalis sulcata ticks collected in croatia. | 2014 | 25377719 |
| rickettsia spp. in seabird ticks from western indian ocean islands, 2011-2012. | we found a diversity of rickettsia spp. in seabird ticks from 6 tropical islands. the bacteria showed strong host specificity and sequence similarity with strains in other regions. seabird ticks may be key reservoirs for pathogenic rickettsia spp., and bird hosts may have a role in dispersing ticks and tick-associated infectious agents over large distances. | 0 | 24751287 |
| detection of rickettsia hoogstraalii, rickettsia helvetica, rickettsia massiliae, rickettsia slovaca and rickettsia aeschlimannii in ticks from sardinia, italy. | tick-borne diseases represent a large proportion of infectious diseases that have become a world health concern. the presence of rickettsia spp. was evaluated by standard pcr and sequencing in 123 ticks collected from several mammals and vegetation in sardinia, italy. this study provides the first evidence of the presence of rickettsia hoogstralii in haemaphysalis punctata and haemaphysalis sulcata ticks from mouflon and rickettsia helvetica in ixodes festai ticks from hedgehog. in addition, ric ... | 2017 | 28110915 |
| molecular detection of spotted fever group rickettsiae in ticks removed from humans in turkey. | a total of 229 attached hard ticks were collected from humans in yozgat province (turkey) in 2009. all ticks were individually examined for the presence of spotted fever group (sfg) rickettsiae using the polymerase chain reaction (pcr) targeting rickettsial citrate synthase (glta) and outer membrane protein (ompa) genes. rickettsial dna was detected in 24 (10.5%) tick samples belonging to dermacentor marginatus (sulzer) (9 males, 3 females), hyalomma marginatum koch (8 males, 2 females) and haem ... | 2016 | 27131413 |
| rickettsia lusitaniae sp. nov. isolated from the soft tick ornithodoros erraticus (acarina: argasidae). | in this study a novel rickettsia from the spotted fever group, isolated from ornithodoros erraticus soft ticks collected from pigpens in the south of portugal, is described. after initial screening revealed rickettsia-positive ticks, isolation attempts were then performed. successful isolates were achieved by shell-vial technique using vero e6 cells at 28°c. molecular characterization of the isolate was performed based on analysis of five rickettsial genes glta, ompa, ompb, sca1 and htr with the ... | 2014 | 24513450 |
| candidatus rickettsia hoogstraalii in ethiopian argas persicus ticks. | ethiopian soft ticks argas persicus, hard ticks including both amblyomma variegatum and rhipicephalus (boophilus) spp., and fleas were collected from livestock, traditional human dwellings, and cracks and crevices of trees. they were assessed in pools for the presence of rickettsia using pcr-based methods. the extracted tick dna was subjected to molecular screening for rickettsia, which revealed 50.5% of the pooled samples to be positive for rickettsia spp. these were then subjected to multi-gen ... | 2012 | 23140898 |
