| tick infection rates with borrelia: ixodes ricinus versus haemaphysalis concinna and dermacentor reticulatus in two locations in eastern germany. | unfed nymphal ixodes ricinus, haemaphysalis concinna, and adult dermacentor reticulatus were collected in two locations of saxony in july and september 1991 by flagging. in july, the abundance of nymphal i. ricinus was about 2-3 times higher than that of nymphal h. concinna, a time of the year when nymphs of both species are reported to have a seasonal peak of activity. no d. reticulatus were flagged concurrently. in september, host-seeking activity of nymphal i. ricinus was again quite high as ... | 1992 | 1463902 |
| 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 |
| tick-borne encephalitis (tbe) virus prevalence and virus genome characterization in field-collected ticks (ixodes ricinus) from risk, non-risk and former risk areas of tbe, and in ticks removed from humans in germany. | tick-borne encephalitis (tbe) is recognized as the most important viral tick-borne zoonosis in 27 countries in europe. in this study, ticks were collected in germany from two non-risk areas in the states of saxony-anhalt and mecklenburg-western pomerania, where several single human tbe cases have occurred in recent years. ticks were also collected from a region in thuringia, known to be a former risk area for tbe virus (tbev), where numerous human cases were reported between 1960 and 1975. detec ... | 2010 | 19906276 |
