| genotypic and biological characteristics of non-identified strain of spotted fever group rickettsiae isolated in crimea. | a strain of rickettsiae, designated crimea-108, was isolated from ticks dermacentor marginatus in the crimea in 1977. its immunobiological characteristics involve low pathogenicity for experimental animals, moderate infectivity for chick embryos, and antigenic relatedness to spotted fever group (sfg) rickettsiae (r. sibirica, r. conorii, r. akari), especially to r. sibirica. the genotypic characterization of the strain crimea-108 was carried out in comparison with sfg and typhus group rickettsia ... | 1993 | 7912040 |
| [results of the 20-year study of tick-borne encephalitis in crimea]. | the history of tick-borne encephalitis (tbe) study in the crimea was retraced and the possibility of introduction of tbe virus to the crimea in the process of the acclimatization of vertebrates from areas enzootic for tbe is discussed. the foci of tbe were found throughout the whole of the mountain forest zone of the crimea and coincided with the habitat area of lxodes ricinus, the main vector of tbe. such ticks as dermacentor reticulatus, d. marginatus and hyalomma marginatum were also found to ... | 2001 | 11548243 |
