Natural infection with two genotypes of Cryptosporidium in red squirrels (Sciurus vulgaris) in Italy
Original language description
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.

Czech description
Bylo vyšetřeno 141 vzorků trusu získaných ze 70 veverek obecných pocházejících ze dvou lokalit západních Alp v Itálii. U 17 zvířat (24,3%) byla prokázána infekce kryptosporidiemi. Na základě sekvence 18S rRNA byly detekovány dva genotypy kryptosporidií:15 veverek bylo pozitivních na Cryptosporidium ferret genotyp a 2 na Cryptosporidium chipmunk genotyp I. Nebyl zjištěn rozdíl mezi výskytem a intenzitou infekce v závislosti na pohlaví zvířat a lokalitou. Více než 85% infikovaných zvířat bylo dospělých;rozdíl mezi věkovými skupinami nebyl zjištěn. Oocysty Cryptosporidium ferret genotypu měřily 5.5 x 5.2 ?m a Cryptosporidium chipmunk genotypu I 5.8 x 5.4 ?m. Neonatální a adultní myši infikované dávkou 1 x 103 čerstvých oocyst obou genotypů nevykazovalydetekovatelnou infekci.
