Percepción del riesgo en el proceso de producción de vacunas aviares
Risk perception in the avian vaccine production process

La importancia que tienen para la avicultura cubana el virus de la enfermedad infecciosa de la bolsa (Gumboro) y el virus de la viruela aviar, así como la producción de vacunas que permitan controlar las enfermedades producidas por estos agentes biológicos, justifican la necesidad del establecimiento ...

Helminth and ectoparasitic faunas of the Harris's hawk, Parabuteo unicinctus (Accipitriformes: Accipitridae), in Chile: new data on host-parasite associations for Neotropical raptors

Abstract Birds of prey harbor a wide spectrum of various parasites, mostly with a heteroxenous life cycle. However, most reports on their parasites come from Europe. Although the Harris's hawk (Parabuteo unicinctus) is a widespread species in America, parasitological surveys on this hawk are mostly focus...

Ectoparasites of Columbina passerina insularis (Columbiformes) in the National Zoological Park, Havana, Cuba

Abstract Ectoparasites of 18 free-living Cuban Ground Doves, Columbina passerina insularis (Columbiformes: Columbidae), captured in the National Zoological Park, Havana, Cuba, were identified. The collected ectoparasites included two species of lice (Phthiraptera: Ischnocera): Columbicola passerinae (77....

Gastrointestinal parasites in captive and free-living wild birds in Goiania Zoo

Braz. j. biol; 82 (), 2022
Helminths are endoparasites that infect a variety of bird species. Endoparasite infections can cause severe diseases, including kill captive avian hosts and represents a problem to maintenance and conservation. The eggs and larval forms of these parasites are usually eliminated in the host feces. The mai...

Identification and Characterization of the ATG8, a Marker of Eimeria tenella Autophagy

Abstract Autophagy plays an important role in maintaining cell homeostasis through degradation of denatured proteins and other biological macromolecules. In recent years, many researchers focus on mechanism of autophagy in apicomplexan parasites, but little was known about this process in avian coccidia....
