Between-year variation and spatial dynamics of Cryptosporidiumspp. and Giardiaspp. infections in naturally infected rodent populations
SUMMARY Prevalence and abundance of Cryptosporidium spp. and Giardia spp. infections were studied over the 8-year period in 3 species of rodents in N.E. Poland (bank vole Myodes glareolus -1523; yellow-necked mouse Apodemus flavicollis- 638; common vole Microtus arvalis- 419). Prevalence was 53·8, 2...
