A new method for obtaining blood from a small mammal without injuring the animal: use of Triatomid bugs

Summary By means of hungry Triatomid bugs, samples of blood (40–200l) can be obtained from small mammals, such as bats, without causing any harm to the animals. The blood can be extracted from the gaster of the bug immediately after the bug has finished sucking. The method was successfully used for measuring the energy budget by the doubly labeled water method, and for obtaining material for lymphocyte cultures, and may prove useful in other fields, too.M.
