Pathogenicity of Microtetrameres centuri Barus, 1966 (Nematoda: Tetrameridae) in Meadowlark.
Pathogenicity of adult and third-stage Microtetrameres centuri Barus, 1966 in meadowlarks (Sturnella spp.) is reported for the first time. Adults do not encyst; their effects are mainly mechanical. Some glandular atrophy of its avian host is detected but no marked inflammatory response is exhibited. Juveniles also encyst experimentally in the perivisceral sinus of the grasshopper (alternate host) hemocoel.
