EXPERIMENTAL TOXOPLASMOSIS IN BUDGERIGARS (MELOPSITTACUS UNDULATUS)

Journal of Parasitology, 2002
The susceptibility of budgerigars (Melopsittacus undulatus) to graded doses of Toxoplasma gondii oocysts was studied. Sixteen budgerigars were divided into 4 groups (A-D) of 4 each. Birds in groups A-C were fed 100,000, 1,000, or 100 infective oocysts of the VEG strain of T. gondii, respectively.

Auditory Pathways in the Budgerigar

Brain, Behavior and Evolution, 2008
The projections of two telencephalic areas in receipt of projections from the auditory relay nucleus of the thalamus (nucleus ovoidalis) were studied in the budgerigar (Melopsittacus undulatus) with autoradiographic methods. These nuclei are called field ''L'' and neostriatum intermedium pars dorsolateralis (NIDL). The results show that neurons in both
