| liver microbiome of peromyscus leucopus, a key reservoir host species for emerging infectious diseases in north america. | microbiome studies generally focus on the gut microbiome, which is composed of a large proportion of commensal bacteria. here we propose a first analysis of the liver microbiome using next generation sequencing as a tool to detect potentially pathogenic strains. we used peromyscus leucopus, the main reservoir host species of lyme disease in eastern north america, as a model and sequenced v5-v6 regions of the 16s gene from 18 populations in southern quebec (canada). the lactobacillus genus was fo ... | 2017 | 28412525 |
| associations between ixodes scapularis ticks and small mammal hosts in a newly endemic zone in southeastern canada: implications for borrelia burgdorferi transmission. | immature ixodes scapularis infestation and borrelia burgdorferi infection of wild small mammals were studied from june to october in 2007 and from may to october in 2008 at 71 study sites in a zone where i. scapularis populations and environmental lyme disease risk are emerging in southwestern quebec. seasonal host-seeking activity of immature i. scapularis was similar to patterns reported previously in canada and the usa: nymphal activity peaked in spring while larval activity peaked in late su ... | 2011 | 22108010 |
| admixture on the northern front: population genomics of range expansion in the white-footed mouse (peromyscus leucopus) and secondary contact with the deer mouse (peromyscus maniculatus). | range expansion has genetic consequences expected to result in differentiated wave-front populations with low genetic variation and potentially introgression from a local species. the northern expansion of peromyscus leucopus in southern quebec provides an opportunity to test these predictions using population genomic tools. our results show evidence of recent and post-glacial expansion. genome-wide variation in p. leucopus indicates two post-glacial lineages are separated by the st. lawrence ri ... | 2017 | 28902189 |
| microsatellite markers reveal low frequency of natural hybridization between the white-footed mouse (peromyscus leucopus) and deer mouse (peromyscus maniculatus) in southern quebec, canada. | in some parts of southern quebec, two closely related rodent species - the white-footed mouse (peromyscus leucopus) and the deer mouse (peromyscus maniculatus) - have recently come in contact because of climate-driven changes in the distribution of the former. both species share similar morphology, ecology, and life history traits, which suggests that natural hybridization may be possible. hybridization among these two species can have important implications on the ecological roles these rodents ... | 2017 | 28177836 |
