Salivary glands in ixodid ticks: control and mechanism of secretion.
The salivary glands are vital to the biological success of ixodid ticks and the major route for pathogen transmission. Important functions include the absorption of water vapor from unsaturated air by free-living ticks, excretion of excess fluid for blood meal concentration, and the secretion of bioactive protein and lipid compounds during tick feeding. Fluid secretion is controlled by nerves. ...
متن کاملThe influence of various factors on fluid secretion by in vitro salivary glands of ixodid Ticks.
1. Salivary glands of the female ixodid tick, Dermacentor andersoni, secrete fluid in vitro when bathed in a slightly modified version of the mammalian tissue culture medium 'TC 199'. 2. Rate of salivation in vitro increases with progression of feeding, but there is no comparable increase in dry weight of the salivary glands during the early phase of engorgement. Engorged ticks secreted at only...
متن کاملVasoconstriction induced by salivary gland extracts from ixodid ticks.
In their quest for blood, most haematophagous parasites secrete vasodilators in their saliva to counter the host haemostatic response of vasoconstriction. Surprisingly, salivary gland extracts from adult female Dermacentor reticulatus and Rhipicephalus appendiculatus ticks induced constriction in a rat femoral artery model; males induced vasoconstriction or vasodilation depending on the time of...

متن کاملIxodid ticks on dogs in southern Mozambique.
The objective of this study was to determine the species and distribution of ticks infesting domestic dogs in southern Mozambique. To this end 89 collections were taken from dogs and the geographic coordinates of the localities at which they were made noted. Fifty-eight of these collections were from animals in the city of Maputo and 16 from animals at rural settlements close to Maputo. A furth...
