| avian poxvirus in a free-range juvenile speckled (rock) pigeon (<i>columba guinea</i>). | a flightless wild juvenile rock pigeon (columba guinea) with pox-like lesions was picked up on the premises of the faculty of veterinary science, university of pretoria, onderstepoort. the pigeon was housed overnight for possible treatment the following day but died before any other intervention could be instituted. at necropsy, coalescing masses of yellowish nodular cutaneous tumour-like lesions principally on the featherless areas were noticed on the dead pigeon's head as well as the beak. his ... | 2015 | 28235295 |
| evolution in columbidae: additional relationships among the antigenic specificities produced by gene interaction. | two of the antigenic characters of erythrocytes, that in either identical or related forms differentiate four species of streptopelia (chinensis, humilis, orientalis, and senegalensis) from a fifth (s. risoria) by interaction of the causative genes, are involved in the appearance in backcross hybrids of additional antigenic specificities to those of the parental species. the cells of backcross hybrids, resulting from matings of s. chinensis x s. risoria and backcrossing to s. risoria, in which t ... | 1972 | 4117013 |
| some protozoan parasites of wild birds from the vicinity of onderstepoort. | the protozoan parasites of wild birds from the vicinity of onderstepoort are recorded. new host records for the republic of south africa are: haemoproteus in threskiornis aethiopicus, francolinus swainsonii, columba guinea and streptopelia senegalensis; leucocytozoon in anas erythrorhyncha, netta erythrophthalma, c. guinea and passer domesticus and plasmodium in numida meleagris. | 1975 | 810756 |
| research note: detection of infectious bursal disease virus antibodies in free-living wild birds in zaria, nigeria. | infectious bursal disease virus (ibdv) is an immunosuppressive pathogen of poultry causing great economic losses to the poultry industry. in this study, the ibdv antibodies were detected in captured free-living wild birds in zaria, nigeria. one hundred and fifty free-living wild birds, comprising 30 birds each of 5 different species, were sampled over a period of 9 months. blood samples were collected from each bird, and harvested sera were tested for ibdv antibodies using enzyme-linked immunoso ... | 2020 | 32241478 |

| introgression of regulatory alleles and a missense coding mutation drive plumage pattern diversity in the rock pigeon. | birds and other vertebrates display stunning variation in pigmentation patterning, yet the genes controlling this diversity remain largely unknown. rock pigeons (columba livia) are fundamentally one of four color pattern phenotypes, in decreasing order of melanism: t-check, checker, bar (ancestral), or barless. using whole-genome scans, we identified ndp as a candidate gene for this variation. allele-specific expression differences in ndp indicate cis-regulatory divergence between ancestral and ... | 2018 | 30014848 |
