The Lyme disease agent Borrelia burgdorferi is primarily transmitted to vertebrates by Ixodes ticks. The classical and alternative complement pathways are important in Borrelia eradication by the vertebrate host. We recently identified a tick salivary protein, designated P8, which reduced complement-mediated killing of Borrelia. We now discover that P8(More)
Lyme borreliosis has become the most common vector-borne illness in North Eastern USA and Europe. It is a zoonotic disease, with well-defined symptoms, caused by B. burgdorferi sensu lato, and transmitted by ticks. Lyme borreliosis is endemic in the Netherlands with a yearly incidence of approximately 133 cases/100,000 inhabitants. Similar to another(More)
The causative agent of Lyme borreliosis, the spirochete Borrelia burgdorferi, has been shown to induce expression of the urokinase receptor (uPAR); however, the role of uPAR in the immune response against Borrelia has never been investigated. uPAR not only acts as a proteinase receptor, but can also, dependently or independently of ligation to uPA, directly(More)
Borrelia burgdorferi transmission to the vertebrate host commences with growth of the spirochete in the tick gut and migration from the gut to the salivary glands. This complex process, involving intimate interactions of the spirochete with the gut epithelium, is pivotal to transmission. We utilized a yeast surface display library of tick gut proteins to(More)
The causative agent of Lyme borreliosis, Borrelia burgdorferi, is transmitted by Ixodes ticks. During tick feeding, B. burgdorferi migrates from the tick gut to the salivary glands from where transmission to the host occurs. B. burgdorferi-interacting tick proteins might serve as vaccine targets to thwart B. burgdorferi transmission. A previous screening(More)
The purpose of this study was to compare guideline recommendations and day-to-day practice of serological testing for Lyme borreliosis (LB) in a laboratory located in Amsterdam, the Netherlands, serving both regional hospitals and primary care physicians. By telephone interview, we obtained clinical information regarding 488 requests for LB serology.(More)
To provide better care for patients suspected of having Lyme borreliosis (LB) we founded the Amsterdam Multidisciplinary Lyme borreliosis Center (AMLC). The AMLC reflects a collaborative effort of the departments of internal medicine/infectious diseases, rheumatology, neurology, dermatology, medical microbiology and psychiatry. In a retrospective case(More)
INTRODUCTION We previously identified tick salivary lectin pathway inhibitor (TSLPI) in Ixodes scapularis, a vector for Borrelia burgdorferi sensu stricto (s.s.) in North America. TSLPI is a salivary protein facilitating B. burgdorferi s.s. transmission and acquisition by inhibiting the host lectin complement pathway through interference with mannose(More)
