| [human granulocytic ehrlichiosis. new tick bite disease lies in wait also in german forests]. | hge is an uncommon zoonosis, transmitted to humans by ticks (ixodes ricinus). heavily exposed persons, such as foresters and forestry workers, are most at risk of infection. hge usually runs an asymptomatic and self-limiting course. symptoms include acute pyrexial illness, frequently accompanied by muscle pain, headache, nausea and vomiting. treatment is with doxycycline/tetracycline or rifampicin. in a study in hesse of 128 heavily exposed subjects, 19.5% had serum antibodies (ifa test) against ... | 2000 | 11006704 |
| prevalence of borrelia burgdorferi sensu lato in the selected ixodes ricinus (acari: ixodidae) population in weilburg forests, hesse, germany. | we studied the presence of borrelia burgdorferi sensu lato in ixodes ricinus ticks collected in woodland areas in the vicinity of weilburg (hesse, germany). ticks (n = 13,347) were collected in five localities in 1996 and were fixed in 70% ethanol. out of them, 4404 specimens were analysed individually (n = 406) and in 796 pools of 2-10 specimens (n = 3998) by the polymerase chain reaction (pcr). the calculated minimal infection rate of individual and pooled ticks was 0% in larvae (n = 280), 6.9 ... | 2002 | 12141747 |
| tick-borne encephalitis (tbe) in germany--epidemiological data, development of risk areas and virus prevalence in field-collected ticks and in ticks removed from humans. | in germany, 100-300 autochthonous clinical tbe cases have been recorded annually. there are high-risk areas in bavaria and baden-wuerttemberg and ongoing low-risk areas in hesse, thuringia, and the rhineland-palatinate and single cases in saxony. in order to be able to evaluate the epidemiological changes described here, it must be mentioned that a new definition of tbe risk areas was introduced on the district level in 1998 in germany and in 2001 with the new infection protection act (infektion ... | 2004 | 15146987 |
| evidence for an increased geographical distribution of dermacentor reticulatus in germany and detection of rickettsia sp. rpa4. | two studies were performed to elucidate the current distribution of the tick dermacentor reticulatus in germany. in the first one in 2003, a total of 365 dogs from 171 sites in the states of berlin and brandenburg was screened for ticks, and the corresponding outdoor sites that the dogs usually visited were searched for host-seeking ticks by the flagging method. a total of 1155 ticks was removed from the dogs. the majority were ixodes ricinus (88.5%), followed by d. reticulatus (9.1%) and i. hex ... | 2006 | 16524777 |
