| providencia sneebia sp. nov. and providencia burhodogranariea sp. nov., isolated from wild drosophila melanogaster. | multiple isolates of the genus providencia were obtained from the haemolymph of wild-caught drosophila melanogaster fruit flies. sixteen isolates were distinguished from the six previously described species based on 16s rrna gene sequences. these isolates belonged to two distinct groups, which we propose each comprise previously undescribed species. two isolates, designated a(t) and b(t), were characterized by dna sequences of the fusa, lepa, leus, gyrb and iles housekeeping genes, whole-genome ... | 2009 | 19406801 |
| genetic variation in drosophila melanogaster resistance to infection: a comparison across bacteria. | insects use a generalized immune response to combat bacterial infection. we have previously noted that natural populations of d. melanogaster harbor substantial genetic variation for antibacterial immunocompetence and that much of this variation can be mapped to genes that are known to play direct roles in immunity. it was not known, however, whether the phenotypic effects of variation in these genes are general across the range of potentially infectious bacteria. to address this question, we ha ... | 2006 | 16888344 |
