| house finch (haemorhous mexicanus) conjunctivitis, and mycoplasma spp. isolated from north american wild birds, 1994-2015. | sampling wild birds for mycoplasma culture has been key to the study of house finch (haemorhous mexicanus) conjunctivitis, yielding isolates of mycoplasma gallisepticum spanning the temporal and geographic ranges of disease from emergence to endemicity. faced with the challenges and costs of sample collection over time and from remote locations for submission to our laboratory for mycoplasma culture, protocols evolved to achieve a practical optimum. herein we report making m. gallisepticum isola ... | 2016 | 27285414 |
| avian thermoregulation in the heat: resting metabolism, evaporative cooling, and heat tolerance in sonoran desert songbirds. | we examined thermoregulatory performance in seven sonoran desert passerine bird species varying in body mass from 10 to 70g - lesser goldfinch, house finch, pyrrhuloxia, cactus wren, northern cardinal, abert's towhee and curve-billed thrasher. using flow-through respirometry we measured daytime resting metabolism, evaporative water loss and body temperature at air temperatures (tair) between 30° and 52°c. we found marked increases in resting metabolism above the upper critical temperature (tuc), ... | 2017 | 28684465 |
| house finch ( haemorhous mexicanus)-associated mycoplasma gallisepticum identified in lesser goldfinch ( spinus psaltria) and western scrub jay ( aphelocoma californica) using strain-specific quantitative pcr. | : in 1994 mycoplasma gallisepticum was found to be the etiologic agent of house finch ( haemorhous mexicanus) conjunctivitis, a rapidly expanding epidemic caused by a genetically discrete, house finch-associated strain of m. gallisepticum (hfmg). while most prominent in house finches, hfmg has been reported in other members of the family fringillidae, including american goldfinches ( spinus tristis), purple finches ( haemorhous purpureus), pine grosbeaks ( pinicola enucleator), and evening gros ... | 2018 | 29053429 |
