In vitro effect of salivary gland extract from fed Ixodes

ricinus, the competent vector of Lyme borreliosis in Europe, on

the growth of Borrelia burgdorferi sensu lato (B. garinii, B.

afzelii and B. burgdorferi sensu stricto) was examined in BSK-H

medium. Motility rate, concentration of motile spirochetes and

their morphology were estimated at intervals of 0, 2, 4, 6 and 8

days using darkfield microscopy. Salivary gland extract derived

from I. ricinus stimulated markedly the growth of three genomic

species of borreliae. The results confirm a substantial role of

salivary glands in the mechanism of pathogen transmission to

vertebrate host. (© 2010 WILEY-VCH Verlag GmbH & Co. KGaA,
