Growth and helminth infection Considering the weight categories the worm burdens showed a similar profile for male and female voles. General prevalence of infection in both sexes increased and attained its maximum in voles weighing 20-24 g (63.3 and 50.0 %, respectively), but decreased thereafter. As shown in Fig. 4, the general prevalence was higher for males Fig. 5. Prevalence and mean intensity of parasitic helminth species in male M. arvalis by weight category than for females. Different profiles of general prevalence and intensity were found in the two sexes, but the trend of prevalence showed characteristics similar to the intensity seen in females (Fig. 4). In contradiction to females where the maximum of general intensity occurred in 20-24 g animals, in males the general intensity fluctuated and reached the maximum in older specimens (30 < g).H. laevis, T. taeniaeformis larva, P. janickii,A. dentata and T. mustelae were responsible for the maximum of the general
