Resumo: Phagocytosis of pathogens by hemocytes is a rapid-acting immune response and represents a primary means of limiting microbial infection in some species of arthropods. To survey the relative capacity of hemocyte phagocytosis as a function of the arthropod immune response, we examined the extent of phagocytosis among a wide taxonomic range of arthropod species including a decapod crustacean (Litopenaeus vannamei), three ixodid tick species (Amblyomma americanum, Dermacentor variabilis, and lxodes scapularis), a mosquito species (Aedes aegypti), and a larval moth (Manduca sexta). Injected fluorescent beads were used as a model to elicit phagocytosis and were measured by flow cytometry, a technique provided in detail that may be adapted for use with any species of arthropod. The data indicated that smaller arthropods generally had a higher proportion of phagocytic cells than larger arthropods. (C) 2011 Elsevier Inc. All rights reserved.
