Abstract

Mycoplasma gallisepticum infection was diagnosed in a group of chukar partridges, pheasants, and peafowl based on serology and isolation techniques. The farm also had quail, chickens, and ducks. Clinical signs in growing birds consisted of foamy eyes, swollen infraorbital sinuses, respiratory distress, and death. Breeding birds experienced a severe drop in egg production. Histologically, the growing birds exhibited lymphoplasmacytic inflammation of the conjunctiva, sinus, and trachea. The most likely source of infection was either chickens, which had been introduced before the onset of clinical signs, or the chukar partridge breeders, which had been obtained at various hunting field trials. /// Basado en resultados serológicos y técnicas de aislamiento, se diagnosticó la infección por Mycoplasma gallisepticum en un grupo de perdices indias (Alectoris gracea chukar), faisanes (Phasianus colchicus torquatus) y pavos reales (Pavo cristatus). La granja también tenía codornices, pollos y patos. Los signos clínicos en las aves adultas consistían de presencia de espuma en los ojos, inflamación de los senos infraorbitales, dificultad respiratoria y muerte. Las aves reproductoras mostraron una fuerte baja en la producción de huevos. Histológicamente las aves adultas tenían inflamación linfoplasmacítica en la conjuntiva, senos y tráquea. La fuente de infección más probable fueron o los pollos que habían Ilegado antes de la aparición de los signos clínicos, o las perdices indias reproductoras que se habían obtenido en varias expediciones de cacería.
