El acaro rojo de las aves (piojillo de los gallineros, Dermanyssus
gallinae, Acari: Dermanyssidae) es un artropodo que afecta la produccion de aves de corral.
Avian trichomonosis, caused by the protozoan Trichomonas
gallinae, affects bird-eating raptors worldwide.
Trichomonas
gallinae parasitizes a variety of avian orders especially in domestic pigeons (Columba livia domestica, Order Columbiformes).
Trichomoniasis
gallinae is transmitted through contaminated food and water.
Among the species of mites described affecting the industrial egg production in Brazil, hematophagous mites as Dermanyssus
gallinae (Acari: Dermanyssidae) (De Geer, 1778) known as Poultry Red Mite and Ornithonyssus sylviarum (Acari: Macronyssidae) (Canestrini & Fanzago, 1877), known as Northern Fowl Mite, are of great importance.
53 grey partridges (33 domesticated and 20 wild) were infested by seven lice species (Menopon
gallinae, Goniocotes gall, Menacanthus stramineus, Genero columbicola, Lipeurus caponis, Brueelia coquimbana, Coculogaster heterographus), three species of ticks (Haemaphysalis leporispalustris, Ixodes pacificus, Amblyomma maculatum) 2 species of mites (Ornithonyssus syliarum, Dermanyssus
gallinae) and a flea species (Pulex irritans).
For diagnosis of trichomonans
gallinae, wet and sterile swab were taken from surface of mouth, throat and larynx of birds and after preparation slide smears, the samples were studied under the light microscope.
helvetica was detected in 1 CeratophyIlus
gallinae (hen flea).
Se examinaron 110 aves, identificandose 10 especies de piojos: Menacanthus stramineus 80%, Menopon
gallinae 51%, Lipeurus caponis 43%, Goniocotes gigas 32%, Goniocotes
gallinae 15%, Goniodes dissimilis 4%, Colpocephalum sp.
Trichomonas
gallinae has emerged worldwide as a cause of mortality in songbirds (passerine birds).
