Fig. 2. Prevalence and mean intensity of parasitic helminth species in male A. microps by weight category Growth and helminth infection The pattern of infection for male and female mice within a given weight classes was similar, except for the large animals ( > 21 g). Maximum prevalence was observed in mice weighing 18-20 g. The highest general intensity was found in young (11 < g) animals and decreased with the progress of host weight in both males and females. A second peak was also identified in adult female (18-20 g) individuals (Fig. 1). Peaks and profiles of the general prevalence and intensity for male and female mice were derived from different species composition (Fig. 2, Fig. 3). Dominant species of 15-17 g males were H. polygyrus, S. frederici, H. diminuta, H. fraterna and C. globifera and T. taeniaeformis larvae. H. polygyrus, H. fraterna and C. globifera larva showed a higher mean intensity value in this weight category. H. polygyrus, S. frederici, H. fraterna and T. taeniaeformis larva exhibited an increase of infection parallel to host weight and showed a high prevalence in 18-20 g male mice. Of the four above-mentioned helminths, only T. taeniaeformis showed a high mean intensity. At the maximum value of general intensity, the dominant species was S. stroma (Fig. 2). A dentata manifested in only one 14 g male individual.
