Fig. 1 in Apparent effect of chronic Plasmodium infections on disease severity caused by experimental infections with Mycoplasma gallisepticum in house finches
Fig. 1. Mean severity of eye lesions ± SE (circles), and M. gallisepticum-load (log (qPCR+1)) (triangles) of birds infected through horizontal transmission with the CA2015 strain of M. gallisepticum. Birds in which Plasmodium was detected by PCR (grey symbols) developed more severe disease than birds in which Plasmodium was not found (white symbol). As there is no significant interaction between M. gallisepticum ‾strain and Plasmodium infection (Table 2) the results for the other M. gallisepticum strains are qualitatively similar and therefore not shown.
Data from: Ultrafast evolution and loss of CRISPRs following a host shift in a novel wildlife pathogen, Mycoplasma gallisepticum
Measureable rates of genome evolution are well documented in human pathogens but are less well understood in bacterial pathogens in the wild, particularly during and after host switches. Mycoplasma gallisepticum (MG) is a pathogenic bacterium that has evolved predominantly in poultry and recently jumped to wild house finches (Carpodacus mexicanus), a common North American songbird. For the first time we characterize the genome and measure rates of genome evolution in House Finch isolates of MG, as well as in poultry outgroups. Using whole genome sequences of 12 House Finch isolates across a 13-year serial sample and an additional four newly sequenced poultry strains, we estimate a nucleotide diversity in House Finch isolates of only ~2% of ancestral poultry strains and a nucleotide substitution rate of 0.8 – 1.2 X 10-5 per site per year both in poultry and in House Finches, an exceptionally fast rate rivaling some of the highest estimates reported thus far for bacteria. We also found high diversity and complete turnover of CRISPR arrays in poultry MG strains prior to the switch to the House Finch host, but after the invasion of House Finches, there is progressive loss of CRISPR repeat diversity, and recruitment of novel CRISPR repeats ceases. Recent (2007) House Finch MG strains retain only ~50% of the CRISPR repertoire founding (1994-95) strains and have lost the CRISPR-associated genes required for CRISPR function. Our results suggest that genome evolution in bacterial pathogens of wild birds can be extremely rapid and in this case is accompanied by apparent functional loss of CRISPRs.
