Poland (bank vole<jats:italic>Myodes glareolus<\/jats:italic>-1523; yellow-necked mouse<jats:italic>Apodemus flavicollis-<\/jats:italic>638; common vole<jats:italic>Microtus arvalis-<\/jats:italic>419). Prevalence was 53\u00b78, 28\u00b71 and 62\u00b73% respectively for<jats:italic>Cryptosporidium<\/jats:italic>spp. and 58\u00b73, 24\u00b74 and 74\u00b72% respectively for<jats:italic>Giardia<\/jats:italic>spp. Prevalence and abundance of infection varied markedly across 8 years of the study with 1998 and 2002 being years of higher prevalence and abundance, following changes in the densities of host species. The distribution of intestinal protozoa in forest rodents did not vary in the 3 isolated sites during the 4-year study. In the case of<jats:italic>Cryptosporidium<\/jats:italic>, fewer older animals carried infection and infections of the oldest bank and common voles were relatively milder. In the case of<jats:italic>Giardia<\/jats:italic>in yellow-necked mice, infections were more common in older age classes (2 and 3). The two species showed significant co-occurrence and in animals carrying both species there was a strong significant positive correlation between abundance of infection with each. These data are discussed in relation to the parasite genotypes identified in this region and in respect of the role of various ecological factors in shaping of intestinal protozoa communities.<\/jats:p>","DOI":"10.1017\/s0031182008004952","type":"journal-article","created":{"date-parts":[[2008,11,10]],"date-time":"2008-11-10T10:24:05Z","timestamp":1226312645000},"page":"1629-1649","source":"Crossref","is-referenced-by-count":28,"title":["Between-year
