Prevalence of R. andersoni microfilariae (RMF) in blood samples drawn from free-ranging cervids. Prevalence is defined as the percentage of samples that tested RMF-positive using a modified Knott’s test. Error bars represent 95 % confidence intervals. a Prevalence of RMF in three species of Minnesota cervids (moose, n = 352; elk, n = 14; white-tailed (WT) deer, n = 36). Blood samples were collected over a four-year period for moose and a two-year period for elk and deer. Fisher’s exact test; P = 0.013. b Comparison of RMF prevalence in Minnesota moose over time (2012, n = 67; 2013, n = 160; 2014, n = 69; 2015, n = 56). Fisher’s exact test; P = 0.607. c Comparison of RMF prevalence in moose from several U.S. states (MN, n = 352; NH, n = 16; ME, n = 14; MT, n = 73; WA, n = 16; AK, n = 27). Fisher’s exact test; P = 0.013. d Image of RMF from Minnesota moose blood. Sample was stained with methylene blue and viewed with a bright light microscope at 200× magnification. Scale-bar: 20 μm
