surveillance of wildlife for mycobacterium bovis infection using culture of pooled tissue samples from ferrets (mustela furo).	to compare culture results of homogenates of pooled lymph nodes from individual ferrets with and without macroscopic lesions of bovine tuberculosis for the presence of mycobacterium bovis, and to determine whether homogenates from 10-30 ferrets could be combined and cultured without loss of sensitivity as a possible method for improving cost-effectiveness of surveillance for m. bovis infection in wildlife populations.	2005	15731829
microbial transport from dairying under two spray-irrigation systems in canterbury, new zealand.	transport through the soil and vadose zone to groundwater of escherichia coli, fecal coliforms, and campylobacter spp. from pasturing of dairy cows was studied on two working dairy farms under a traveling irrigator and a center pivot system. leachate was collected from 1.5 m depth using a large linear lysimeter over a period of 4 yr after rainfall or irrigation applied using a traveling irrigator. there was little transport of fecal coliforms or campylobacter from irrigation applications of 55 m ...	2010	20400578

monitoring theileria orientalis (ikeda)-associated bovine anaemia in affected cattle over time.	the aim of the study was to observe changes in haematocrit (hct) over time in a new zealand south island dairy herd affected by an outbreak of theileria-associated bovine anaemia (taba; ikeda). a secondary aim was to relate individual cow hcts to the amount of theileria orientalis ikeda dna present in the blood, as measured by cycle threshold values, using a quantitative pcr (qpcr). over a 6 month period, blood samples from 19 randomly selected cattle were monitored from a herd of 600 dairy cows ...	2017	28969833
