Název v původním jazyce

Natural infection with two genotypes of Cryptosporidium in red squirrels (Sciurus vulgaris) in Italy

Popis výsledku v původním jazyce

We investigated the genotypes of Cryptosporidium infecting red squirrels in two areas of the Western Alps in Italy. Examination of 141 faecal samples from 70 red squirrels revealed oocysts of Cryptosporidium in 17 animals (24.3%). Based on 18S rRNA genesequencing, two genotypes of Cryptosporidium species were found: 15 squirrels were positive for the Cryptosporidium ferret genotype and 2 for the Cryptosporidium chipmunk genotype I. The occurrence and intensity of Cryptosporidium infection did not differ between the study areas or sex. More than 85% of the positive animals were adults; no difference was found between Cryptosporidium infection in the juvenile and adult age groups. Oocysts of the Cryptosporidium ferret genotype measured 5.5 x 5.2 ?m (shape index 1.06) and the Cryptosporidium chipmunk genotype I 5.8 x 5.4 ?m (shape index 1.07). Neonatal and adult mice inoculated with 1 x 103 fresh oocysts of both genotypes did not produce detectable infection.
