The tick blood meal: from a living animal or from a silicone membrane?
نویسندگان
چکیده
An artificial feeding unit with a reinforced silicone membrane to replace host skin provides ticks with a perch over blood with a tick attachment rate of 75-100%. Some 5 mg of an acaricide like fipronil is sufficient to establish survival curves over different doses down to ppb levels in blood. This in vitro feeding assay for hard ticks is more advantageous than in vivo trials on animals.

Proteases play a key role in protein digestion in ticks and other haematophagous insects. Our understanding of blood meal digestion in digestive system of ticks can be very useful for better understanding of basic rules for control of ticks. Cells of the midgut endocytose blood components. Blood proteins uptake by midgut cells, suggesting the presence of proteases in the midgut cells. In this...
متن کاملAn in vitro feeding assay to test acaricides for control of hard ticks.
Animal husbandry could not be practised over large areas of the planet without acaricides. The prevention of tick bite and the transmission of diseases requires the use of pesticides, but this contributes to the development of tick resistance against acaricides. This drives the quest for new molecules that target physiological processes crucial to tick survival. In vivo trials involve multiple ...

The objective of this study was to evaluate the effects of cottonseed meal (CSM) treated with sodium bentonite (SB) on certain blood components and immune response of laying hens. A 3 × 3 factorial arrangement with 3 levels of SB (0, 10, and 20 g/kg of diet) and 3 levels of CSM (0, 100 and 200 g/kg of diet) were used within 9 dietary treatments of 4 replicates each. Nine mash diets were fed to ...

An experiment was conducted to study the effects of substitution soybean meal (SBM) with canola meal (CM) and formulated diets based on total and digestible amino acid on performance, egg quality, organs weight and blood parameters of laying hens from 73 to 83 weeks of age. A total of 128 laying hens were distributed by completely randomized design in a 2×2 factorial arrangement with 2 protein ...
متن کاملAntigenic and genetic heterogeneity of Borrelia burgdorferi populations transmitted by ticks.
The genome of Borrelia burgdorferi encodes a large number of lipoproteins, many of which are expressed only at certain stages of the spirochete's life cycle. In the current study we describe the B. burgdorferi population structure with respect to the production of two lipoproteins [outer surface protein A (OspA) and outer surface protein C (OspC)] during transmission from the tick vector to the...
