Tetrameres

(tĕ-tram'ĕ-rēz),
A genus of stomach-infecting parasitic nematodes (family Spiruridae) of birds. When filled with eggs, the female worm is enormously enlarged and has a globular, blood-red appearance. Species include Tetrameres americana, found in the proventriculus of chickens (sometimes severely pathogenic in young chicks), turkeys, grouse, and quail, and transmitted by infected cockroaches and grasshoppers, and Tetrameres fissispina, found in the proventriculum of ducks, geese, wild waterfowl, pigeons, and doves but rarely in gallinaceous birds.

Mediante la realizacion de este estudio se logro determinar la presencia de al menos un parasito en el 96% de las aves, es decir, el 4% de las aves no estaban infectadas por estos parasitos; ademas se logro establecer la presencia de Coccidia como el parasito de mayor prevalencia con el 93%, siendo los de menor prevalencia Ascaridia (12%), Trichuris (5%), Heterakis (3%), Tetrameres (2%), Amidostomum (1%), Raillietina (1%) y Toxocara (1%).
