Parrots (order: Psittaciformes) are the most common captive birds and have attracted human fascination since ancient times because of their remarkable intelligence and ability to imitate human speech. However, their genome organization, evolution and genomic relation with other birds are poorly understood. Chromosome painting with DNA probes derived from the flow-sorted macrochromosomes (1-10) ...

background: toxoplasmosis, a worldwide zoonotic disease, is caused by toxo­plasma gondii . the distribution of genetic diversity of t. gondii in wild animals is of great importance to understand the transmission of the parasite in the environ­ment. however, little is known about t. gondii prevalence in wild animals and birds in china. methods: we conducted the genetic characterization of t. gon...

62, Date Sunday, Jan 27 2002 1:00PM 12:00PM Session D3 Sound Localization Investigations of the Precedence Effect in Budgerigars (Melopsittacus undulatus) Micheal L. Dent, Robert J. Dooling The precedence effect has previously been found in mammals, anurans, invertebrates, and one species of bird, the barn owl. Here, the precedence effect was measured in a small parrot, the budgerigar (Melopsit...

It is well established that in many avian species, prenatal maternal resource allocation varies both between and within clutches and may affect offspring fitness. Differential allocation of maternal resources, in terms of egg weight and yolk composition, may therefore allow the female to adjust brood reduction and to fine-tune reproductive investment in accordance with the expected fitness retu...

BACKGROUND Although standard skin prick test (SPT) panels are crucial for routine investigation of sensitization in daily clinical practice, it has limitations in terms of missing allergens. OBJECTIVE To find out sensitization rates (SR)s to additional panel of allergens and their relative contributions in allergic diseases. METHODS SPTs with a battery of aeroallergens [tree pollen (A.gluti...
