Changes in probability and intensity of the infection during the course of the experiment. (a) The probability of infection gradually decreased after the first week and by 30 days post-inoculation, most newts tested negative for Bd (GLMM: days post-inoculation; χ2 = 30.12, df = 3, p < 0.0001; interaction sex x days post-inoculation χ2 = 2.68, df = 3, p = 0.44). (b) The average infection burden was constant until 2 weeks after inoculation; during the third week after inoculation the infection intensity started to decline and generally reached zero at day 30 post-inoculation (GLMM: days post-inoculation; χ2 = 9.20, df = 3, p < 0.001; interaction sex x days post-inoculation χ2 = 0.01, df = 3, p = 0.99). Figures show predicted means ± SE generated from the mixed model analyses. In both analyses, tank had no influence on patterns of Bd infection (tank component = 0), but there was some consistency in the prevalence of Bd infection within versus among individuals (component = 0.01 ±0.009 (S.E.)) and a significant difference between individuals in Bd loads (component = 0.12 ±0.004 (S.E.)).
