First Report of Coccidiosis and Gizzard Erosion in a Zebra Finch (Taeniopygia guttata) of Iran
Coccidiosis and gizzard erosion are rare conditions in cage bird. A male zebra finch was presented with a history of watery diarrhea, anorexia, ruffled feathers, weight loss, and lethargy and died finally. Gross necropsy revealed small areas of erosions and hemorrhages on the gizzard wall. The intestine was oedematous. The spleen appeared pale and small. The testes were asymmetric.Histologicall...
متن کاملEnhanced expression of tubulin-specific chaperone protein A, mitochondrial ribosomal protein S27, and the DNA excision repair protein XPACCH in the song system of juvenile male zebra finches.
Recent evidence suggests that sexual dimorphisms in the zebra finch song system and behavior arise due to factors intrinsic to the brain, rather than being solely organized by circulating steroid hormones. The present study examined expression of 10 sex chromosome genes in the song system of 25-day-old zebra finches in an attempt to further elucidate these factors. Increased expression in males...
متن کاملSystemic Amyloidosis and Testicular Interstitial Tumor in a Zebra Finch (Taeniopygia guttata): a Case Report in Iran
Systemic amyloidosis and testicular interstitial tumor are rare conditions in birds and this is the first report in Iran. A male zebra finch was presented because of white diarrhea, anorexia, loss of weight and lethargy. At necropsy, the small intestine was edematous and congested. The spleen appeared pale. The liver was large, firm and brown. One testis was cystic and neoplastic and the remain...
متن کاملUsing Digital Images of the Zebra Finch Song System as a Tool to Teach Organizational Effects of Steroid Hormones: A Free Downloadable Module
Zebra finch song behavior is sexually dimorphic: males sing and females do not. The neural system underlying this behavior is sexually dimorphic, and this sex difference is easy to quantify. During development, the zebra finch song system can be altered by steroid hormones, specifically estradiol, which actually masculinizes it. Because of the ease of quantification and experimental manipulatio...
متن کاملSexual differentiation of the zebra finch song system.
The song system of zebra finches (Taeniopygia gutatta) is highly sexually dimorphic. Only males sing, and the brain regions and muscles controlling song are much larger in males than in females. Development of the song system is highly sensitive to steroid hormones. However, unlike similar sexually dimorphic systems in other animal models, masculinization of song system structure and function i...
