Sentence examples for infecting vectors from inspiring English sources

Once inside, parasites invade several kinds of cells through a lysosome-mediated mechanism, differentiating into amastigotes that replicate and transform into trypomastigotes causing host cell lysis that releases parasites into the bloodstream; the parasites are then capable of invading other cells or infecting vectors that make a meal of the host [ 50].

With this strategy, all the controls are used to optimize the objective function J. From Figures 12 and 13 we can see that this control strategy results in a significant decrease in the number of infected pines and infected vectors.

The unit of population was the farm, with farms divided into four classes: susceptible (no hosts or vectors infected with BTV); exposed (has acquired infection); infectious (has acquired infection and the first newly infected vectors on the farm have completed their extrinsic incubation period); and recovered (no longer any hosts or vectors infected with BTV).

Figures 9 and 10 show that decrease in the number of infected pine trees and infected vectors occurs by applying these controls.

More complex scenarios involve introduction of infected host populations or infected vectors becoming newly established upon arrival.

The acute viremic phase in monkeys is followed by solid immunity, and although persistent infection has been documented for some primate species in the laboratory, such infections are probably not accompanied by viremia levels sufficient to infect vectors (4, 5 ).
