| prevalence and abundance of cryptosporidium parvum and giardia spp. in wild rural rodents from the mazury lake district region of poland. | prevalence and abundance of cryptosporodium parvum and giardia spp. were studied in 3 species of rodents from forests and abandoned agricultural fields in n.e. poland (clethrionomys glareolus n = 459; microtus arvalis n = 274; apodemus flavicollis n = 209). overall prevalence was consistently higher in the voles compared with a. flavicollis (70.6, 73.0 and 27.8% respectively for c. parvum and 93.9, 96.3 and 48.3% respectively for giardia spp.). prevalence and abundance of infection also varied m ... | 2002 | 12166517 |
| preliminary molecular characterization of cryptosporidium parvum isolates of wildlife rodents from poland. | isolates of cryptosporidium were collected from 3 species of woodland and field rodents (clethrionomys glareolus, microtus arvalis, and apodemus flavicollis) and were characterized by polymerase chain reaction amplification and sequencing of fragments of the oocyst wall protein (cowp) gene and of the 18s ribosomal rna gene. sequence analysis of these markers revealed that the animals were infected with c. parvum, and that the genotype involved was almost identical to the mouse genotype previousl ... | 2003 | 14627156 |
| biological characterisation of cryptosporidium parvum isolates of wildlife rodents in poland. | the study was undertaken to characterise the c. parvum isolates originating from naturally infected woodland and field rodents: clethrionomys glareolus (cg), apodemus flavicollis (af) and microtus arvalis (ma). we found that the measurements of oocyst dimensions and oocyst morphology did not allow distinction between the parasite isolates from the 3 rodent species. the mean dimensions were: for cg 4.67 x 4.21, for af 4.65 x 4.14 and for ma 4.66 x 4.16. these 3 groups of isolates have produced si ... | 2003 | 14677907 |
| [the co-occurence of cryptosporidium parvum, giardia spp. and helminth infections in small rodent populations]. | during long-term (1998-2000) studies on rodent parasite populations in mazury lake district there were collected and analyzed data on co-occurrence of intestinal protozoa (cryptosporidium parvum, giardia spp.) and helminths. there were performed 178 autopsies of common vole microtus arvalis, 85 autopsies of yellow-necked mouse apodemus flavicollis and 386 autopsies of bank vole clethrionomys glareolus. positive effect of helminth infections was found in c. glareolus. voles infected with nematode ... | 2004 | 16859041 |
| [the ecology of cryptosporidium parvum infection in small rodent populations]. | the prevalence and abundance of cryptosporidium parvum were studied over a three year period (1997-1999) in three species of rodents sampled from forest and abandoned fields in the mazury lake district, poland. the overall prevalence was consistently higher in voles compared with apodemus flavicollis (70.6% in clethrionomys glareolus, 73.0% in microtus arvalis and 27.8% in a. flavicollis). the prevalence and abundance of infection also varied across the 3 years of the study with 1998 being the y ... | 2001 | 16886421 |
