borrelia persica and b. baltazardi sp. nov.: experimental pathogenicity for some animals and comparison of the ultrastructure.	the ultrastructure of cells of borrelia persica was compared with that of cells of a new isolate of barrelia (borrelia "x"). this organism (b. "x") was isolated in a region of iran where b. persica is already known to exist. the morphology of the cells of the two strains differed in mean cell length and cell diameter. cells of b. persica were covered by a regularly structured surface layer, while those of b. "x" possessed an amorphous surface coat. furthermore, the strains differed in their expe ...	1979	533068
[an experimental quantitative assessment of the efficiency of borrelia persica transmission by ornithodoros papillipes ticks. 1. 2 forms of borreliemia in guinea pigs].	experimental borreliosis in guinea pigs caused by ticks' bites assumed two forms--typical and mild, the latter being encountered in 40% of cases. mild form significantly differs from the typical one in some indices of borreliemia: intensity, duration, time of onset and cessation, absence of fluctuations in the number of borrelia. the form is not easily diagnosed by the analysis of animal blood preparations, which should be taken into consideration in experimental and clinical practice. in mild f ...	1990	2215365
[treatment of borrelia infected ticks (author's transl)].	the ornithodorus tholozani, carrier and main reservoir of borrelia persica, causing agent of the regional recurrent fever in iran, gets rid of the infection by stuffing in blood containing a cycline type antibiotic, in an adequate concentration. the treatment efficiency is 100%, confirmed on 60 infected ticks who showed to be free from borrelia after a treatment meal, so that the crushing of their whole body, inoculated to the guinea-pig, the most sensitive animal to borrelia persica, remains al ...	1982	7105283
phylogenesis of relapsing fever borrelia spp.	the phylogenetic relationships of 20 relapsing fever (rf) borrelia spp. were estimated on the basis of the sequences of rrs genes. complete sequences were aligned and compared with previously published sequences, and the similarity values were found to be 97.7 to 99.9%. phylogenetic trees were constructed by using the three neighbor-joining, maximum-parsimony, and maximum-likelihood methods. the results of the comparative phylogenetic analysis divided the rf borrelia spp. into three major cluste ...	1996	8863409
[a great franco-mauritian epidemiologist: joseph désiré tholozan (1820-18970].	born in 1820 from french parents in diego garcia, an islet then linked to mauritius where he started in port-louis his school years, joseph désiré tholozan was an original personality. he undertook medical studies in france (m. d. thesis, paris, 1843) after having joined the military health service (1841) as a surgeon serving in various garrisons in the country and later at the hospital of the valde-grâce in paris (1849). successful at the "agrégation" of medicine in 1853, he later participated ...	1998	9559181
[new solid culture media for growing borrelia persica and borrelia microti].	a new solid means for the fast detection of borrelia persica and borrelia microti is described. generally, culture and isolation of borrelia takes about 21 days. the serological test, which is carried out more often, takes less time but it is associated with false positive reactions relatively high. however, our new solid means reduces the culture time to 72 hours, allowing to have a fast diagnosis of the disease caused by borrelia persica and borrelia microti, and to start the early treatment o ...	1996	9768268
[joseph désiré tholozan and the persian relapsing fever].	in the year 1879, tholozan seems to have been convinced of the danger caused by the bites of ornithodores in persia, as a result of very careful observations of sick persons suffering from iranian relapsing fever due to borrelia persica. among the ticks collected by him and sent to entomologists in france was the true vector, named argas (presently ornithodoros) tholozani by laboulbene and megnin. tholozan's contribution to our knowledge on persian relapsing fever is really important. he was one ...	1998	11625357
purification of periplasmic flagellar antigen from borrelia microtti.	borrelia microtti and borrelia persica are 2 iranian strains of borrelia found in western asia and responsible for relapsing fever. the outer surface antigens of borrelia undergo variations which are responsible for the relapsing phenomenon. the fixed flagellar antigen is required for diagnosis as the variant antigens cannot be used in serological methods of diagnosis. the fixed flagellar antigen was purified for the first time from the iranian strain of borrelia microtti using detergent treatme ...	2002	12064689
