Table 4 Maximum likelihood estimates (MLE) with a negative log-likelihood value of 1,833.4 of the abundance model parameters for E. multilocularis in foxes in Zurich with their 95% bootstrap confidence intervals (CI) for Model 20, with μ fixed at 8.6

From: Mathematical modelling of Echinococcus multilocularis abundance in foxes in Zurich, Switzerland

Parameter MLE 95% CI  
β 0 8.5 7.5–9.3 Baseline number of parasites of the infection pressure
β p 2.6 1.4–4.1 Amplitude of the infection pressure in the periurban zone
β b 0.1 -0.7–1.5 Amplitude of the infection pressure in the border zone
β u 1.2 -1.3–2.7 Amplitude of the infection pressure in the urban zone
ϕ p 0.5 0.3–1.3 Decrease parasite rate in the periurban zone
