| disseminated mycobacterium celatum infection in a white-tailed trogon (trogon viridis). | an adult female white-tailed trogon (trogon viridis) was presented with abdominal enlargement and hard subcutaneous masses. necropsy findings included bony masses extending from skeletal structures, disseminated pale foci in the liver, and a pale mass in the kidney. histological examination revealed multifocal to coalescing granulomatous inflammation in the bone, liver, kidney, lung and spleen. mycobacterium celatum was isolated from the liver and identified by dna sequencing. this is the first ... | 2006 | 16854645 |
| toward resolving deep neoaves phylogeny: data, signal enhancement, and priors. | we report three developments toward resolving the challenge of the apparent basal polytomy of neoavian birds. first, we describe improved conditional down-weighting techniques to reduce noise relative to signal for deeper divergences and find increased agreement between data sets. second, we present formulae for calculating the probabilities of finding predefined groupings in the optimal tree. finally, we report a significant increase in data: nine new mitochondrial (mt) genomes (the dollarbird, ... | 2009 | 18981298 |
| the first report of mycobacterium celatum isolation from domestic pig (sus scrofa domestica) and roe deer (capreolus capreolus) and an overview of human infections in slovenia. | mycobacterium celatum, a slowly growing potentially pathogenic mycobacterium first described in humans, is regarded as an uncommon cause of human infection, though capable of inducing invasive disease in immunocompromised hosts. according to some reports, a serious disease due to m. celatum may also occur in individuals with no apparent immunodeficiency. in animals, an m. celatum-related disease has been described in three cases only: twice in a domestic ferret (mustela putorius furo) and once i ... | 2011 | 21647336 |
| two new species of brueelia kéler, 1936 (ischnocera, philopteridae) parasitic on neotropical trogons (aves, trogoniformes). | two new species of brueelia are described and illustrated. these new species and their type hosts are: brueelia sueta ex pharomachrus pavoninus (spix, 1824), the pavonine quetzal and brueelia cicchinoi ex trogon viridis linnaeus, the white-tailed trogon. both new species differ from the only brueelia described on trogon mexicanus by many morphological features, including those present in the male genitalia and female vulvar margin. partial sequences of the mitochondrial cytochrome oxidase i (coi ... | 2011 | 21998549 |
