Using indirect immunoperoxidase (IIP), peroxidase anti-peroxidase (PAP) and avidin biotin-peroxidase complex (ABC) immunohistochemical methods, Mycoplasma gallinarum and M gallinaceum antigens were demonstrated in ethanol-fixed paraffin-embedded oviduct sections from hens the eggs from which showed suboptimal hatchability. Specific immunoperoxidase...

Thirteen mycoplasmas were isolated from a peregrine falcon (Falco peregrinus), two saker falcons (Falco cherrug), a buzzard (Buteo buteo), a black vulture (Aegypius monachus), and two griffon vultures (Gypsfuhus). Six of them could be identified: Mycoplasma gallinarum (three isolates), M. columborale (two isolates) and M. anatis (one isolate). The...

An encephalitic disease in pigeons, characterized by paralysis of extremities, torticollis, head tremor, and diarrhea, is described. The negative titers in the hemagglutination tests, the presence of Feulgen-positive intranuclear inclusions in the cells of the granular layer of the cerebellum and the fibroblast culture, and the presence of viral pa...

Following an outbreak of respiratory disease in a group of red-legged partridges (Alectoris rufa) and chickens (Gallus domesticus) housed in the same unit, a mycoplasma was isolated. Its biochemical profile and the growth-inhibition test enabled it to be identified as Mycoplasma synoviae. Histopathological analysis revealed an intense inflammatory...

Los mecanismos patogénicos básicos de las fiebres víricas hemorrágicas y de la Peste Porcina Africana son cxpuestos y discutidos en el presente artículo. Especialmente los mecanismos que conducen a la producción de hemorragias como la trombocitopenia, factores de coagulación, la IDC, la lesión endotelial y la activación de leucocitos serán revisado...
