| [variations in the occurrence of borrelia in the tick, ixodes ricinus (l.) in the olomouc district]. | examinations of 1,998 ticks ixodes ricinus in the district of olomouc revealed 182 cases of borrelia, i.e. in 9.1% ticks. prevalence in males is 10.7%, in females 12.8% and in nymphs 7.0%. a certain coincidence was observed between mosquito incidence, in particular during the first half of the year, and borrelia prevalence in ticks in the course of the following year, with prevalence variations manifested in tick imagos only. a hypothesis is formulated that mosquitos feeding on larger animals, w ... | 1994 | 8168165 |
| [long-term study of natural foci of tick-borne encephalitis in the district of olomouc]. | the incidence of natural foci of tick-borne encephalitis in the olomouc district has been characterized as general. this finding is based on analyses of results of earlier reports and results of serological blood tests of 397 small mammals from localities where probably transmission of the infection to humans occurred. the incidence almost corresponds to the incidence of the tick ixodes ricinus. it has a long-lasting and also cumulative character; the number of reported cases from the main focal ... | 1993 | 8306399 |
| vertical distribution of the tick ixodes ricinus and tick-borne pathogens in the northern moravian mountains correlated with climate warming (jeseníky mts., czech republic). | a study of the vertical distribution of the common tick ixodes ricinus and tick-borne pathogens--tick-borne encephalitis virus (tbev) and genospecies of borrelia burgdorferi s.l.--was performed in the highest part of the jeseniky mountain area (the hrubý jesenik mts. with the highest summit praded, 1,491 m above see level). altogether 1,253 specimens of all tick stages (607 larvae, 614 nymphs, 8 females and 24 males) were collected at the altitude 990-1,300 m above sea level on 12 collection sit ... | 2009 | 20020603 |
