| spatiotemporal homogeneity of campylobacter subtypes from cattle and sheep across northeastern and southwestern scotland. | source attribution using molecular subtypes has implicated cattle and sheep as sources of human campylobacter infection. whether the campylobacter subtypes associated with cattle and sheep vary spatiotemporally remains poorly known, especially at national levels. here we describe spatiotemporal patterns of prevalence, bacterial enumeration, and subtype composition in campylobacter isolates from cattle and sheep feces from northeastern (63 farms, 414 samples) and southwestern (71 farms, 449 sampl ... | 2009 | 19700557 |
