| internal papillomatosis with intrahepatic cholangiocarcinoma and gastrointestinal adenocarcinoma in a peach-fronted conure (aratinga aurea). | a 17-yr-old pet female peach-fronted conure (aratinga aurea) was presented with the chief complaints of mild lethargy and weight loss with increased appetite. antemortem diagnostics included complete blood count, plasma biochemistry, and radiography. abnormal findings included elevated inflammatory parameters (hyperfibrinogenemia) and a space-occupying mass in the region of the liver. histologic examination of a liver biopsy sample indicated bile duct hyperplasia leading to a presumptive diagnos ... | 2004 | 12495076 |
| birds as potential pollinators of the spathodea nilotica (bignoniaceae) in the urban environment. | birds play crucial role on the pollination of many plants. however, little is known about the interactions between nectarivorous neotropical birds and exotic angiosperms. s. nilotica is an exotic african plant widely used in brazilian urban landscaping. however, it has been poorly studied in relation to its interactions with neotropical birds. in this way, we studied the feeding nectar strategies and the interspecific antagonistic behaviours among nectarivorous neotropical birds to verify the bi ... | 2013 | 24789388 |
| problem-solving in a cooperative task in peach-fronted conures (eupsittula aurea). | cooperation is a complex behaviour found in many kinds of organisms and occurs between individuals of the same and different species. several studies have examined the intentionality of this behaviour by testing the animals' understanding of the need for a partner when working in pairs. the mammalian species tested express such understanding, whereas most tested birds fail, especially when the test involves a delayed access to the setup by one of the co-operators. in the present study, the coope ... | 2020 | 31760558 |
| yeasts and filamentous fungi in psittacidae and birds of prey droppings in midwest region of brazil: a potential hazard to human health. | birds of prey and from psittacidae family are host to fungal microbiota and play an important role in the epidemiology of zoonoses. few studies in the literature have characterized mycelial and yeast fungi in the droppings of these birds and correlated the isolates with the zoonotic potential of the microorganisms. droppings from 149 birds were evaluated and divided into two groups: captive: rhea americana araneipes, primolius maracana, ara ararauna, ara chloropterus, anodorhynchus hyacinthinus, ... | 2019 | 30304251 |
| salmonella spp. infection in psittacidae at a wildlife rehabilitation center in the state of mato grosso do sul, brazil. | the growing interest in wild birds as pets and the increasingly complex interspecific relationships due to human activities in wild environments underscore the need for better knowledge about the health of these animals. salmonella stands out among the infectious agents of considerable importance to both animal and human health. the importance of these enterobacteria to the health of humans and livestock animals has long been known. in wild birds in countries such as brazil, however, little is k ... | 2020 | 31880987 |
