A 49-year-old woman complained of cough and a purulent sputum (about 40 ml/day). She kept budgerigars for a period of 30 years, she first noticed a productive cough 10 years previously. Her chest roentgenogram revealed a diffuse reticulonodular pattern. She was diagnosed as having a chronic type of budgerigar breeder's lung associated with chronic bronchitis. Peptostreptococcus anaerobius was c...

cryptosporial and bacterial co-infection is reported in a budgerigar with clinical manifestations of septicemia and respiratory tract infection. microscopically large number of round to oval 2-5μm cryptosporidial organisms were found to be lodged on the parabronchial epithelial cells of the respiratory tract. the bacterial colonies were seen around the parabronchial spaces of the lung tissue. i...

Cannabinoid receptor density and cannabinoid receptor-mediated G protein stimulation were studied by autoradiographic techniques throughout the budgerigar (Melopsittacus undulatus) brain. The maximal CB(1) receptor density value (using [(3)H]CP55,940 as radioligand) was found in the molecular layer of the cerebellum (Mol), and high binding values were observed in the nucleus taeniae amygdalae (...

The auditory brainstem response (ABR) was recorded in adult budgerigars (Melopsittacus undulatus) in response to clicks and tones. The typical budgerigar ABR waveform showed two prominent peaks occurring within 4 ms of the stimulus onset. As sound-pressure levels increased, ABR peak latency decreased, and peak amplitude increased for all waves while interwave interval remained relatively consta...

Striatal projecting neurons, known as medium spiny neurons (MSNs), segregate into two compartments called matrix and striosome in the mammalian striatum. The matrix domain is characterized by the presence of calbindin immunopositive (CB+) MSNs, not observed in the striosome subdivision. The existence of a similar CB+ MSN population has recently been described in two striatal structures in male ...

MOTIVATION A crucial problem in genome assembly is the discovery and correction of misassembly errors in draft genomes. We develop a method called misSEQuel that enhances the quality of draft genomes by identifying misassembly errors and their breakpoints using paired-end sequence reads and optical mapping data. Our method also fulfills the critical need for open source computational methods fo...

A 21-year-old patient experienced asthmatic attacks when cleaning the cage of his budgerigar. Skin tests and radioallergosorbent test were positive to grass pollen and negative for budgerigar feathers and feces. When the food of the bird, a mixture of grain, was tested, a positive reaction to millet was found. Nasal provocation test with millet was positive. Specific immunoglobulin E antibodies...

The three-dimensional structure and size of ostrich sperm is unknown. In this study, the morphology and dimensions of ostrich sperm were determined by scanning electron microscopy of semen samples obtained from sexually mature males during the breeding season. The results indicate that sperm cells of the ostrich are of the sauropsid type characteristic of non-passerine birds and, in general app...
