| house finch populations differ in early inflammatory signaling and pathogen tolerance at the peak of mycoplasma gallisepticum infection. | host individuals and populations often vary in their responses to infection, with direct consequences for pathogen spread and evolution. while considerable work has focused on the mechanisms underlying differences in resistance-the ability to kill pathogens-we know little about the mechanisms underlying tolerance-the ability to minimize fitness losses per unit pathogen. here, we examine patterns and mechanisms of tolerance between two populations of house finches (haemorhous [formerly carpodacus ... | 2013 | 23594550 |
| prevalence of blood parasites in eastern versus western house finches: are eastern birds resistant to infection? | the rapid spread of the bacterial disease, mycoplasma gallisepticum (mg), throughout the introduced range of house finches (carpodacus mexicanus) in eastern north america, compared to its slower spread through the native western range, has puzzled researchers and highlights the need to understand the relative differences in health state of finches from both populations. we conducted a light-microscope survey of hemoparasites in populations of finches from arizona (within the western range) and f ... | 2013 | 23807632 |
| serological and microbial survey of mycoplasma gallisepticum in wild turkeys (meleagris gallopavo) from six western states. | from 1986 to 1989, sera from wild turkeys (meleagris gallopavo), including three subspecies (m. gallopavo intermedia, m. gallopavo merriami and m. gallopavo mexicana) trapped in six western states were tested for antibody to mycoplasma gallisepticum (mg) (n = 724), m. synoviae (ms) (n = 461) and m. meleagridis (mm) (n = 354) using the rapid plate agglutination (rpa) assay. subsamples of these sera were also evaluated using the hemagglutination inhibition (hi) assay for antibody to mg (n = 664) a ... | 1992 | 1548787 |
