Using a Bullet Blender Gold homogenizer (Next Advance, Averill Park, NY, USA), we homogenized whole ectoparasites
in Navy Eppendorf bead tubes (Next Advance) containing 400 [micro]L brain-heart infusion broth (CDC, Atlanta, GA, USA).
However, carcass ectoparasite
findings are considered highly likely to have been influenced by ectoparasites
abandoning dead animals.
Before DNA extraction, the ectoparasites
were washed twice with ethanol (70%) and then with sterile water and dried.

They also play an important role in the survival and ecology of various ectoparasites
including chiggers, ticks, fleas, and lice.

In the industrial layer hens, the species of the genus Megninia are important and responsible ectoparasites
for damages in the eggs' production, being also told in other hosts, as parakeets, turkeys and pigeons (GUIMARAES et al., 2001; TUCCI et al., 2005; REZENDE et al., 2013).

, fowl ticks may cause ruffled feathers, anemia, emaciation and low production.
For example, burrowing owls within their core range are known to remove ectoparasites
by kicking plumes of loose dirt and sand onto their bodies and ruffling their feathers while preening ('dustbathing'; Thomsen, 1971; Garcia, 2005).

It is widely accepted that a link between fish ectoparasites
and bacterial infections coexist (Bandilla et al., 2006).
