In order to acquire prevalence and genetic data on Cryptosporidium infections in captive lizards and snakes kept as pets, a survey was conducted on 150 individual reptiles from southern Italy. Fecal samples were preserved in 5% formalin and analyzed using a commercial immunofluorescence assay (IFA) for the detection of Cryptosporidium oocysts and Giardia cysts. IFA revealed the presence of Cryptosporidium oocysts in nine of the 150 samples examined (6.0%), precisely in 6/125 snakes (4.8%) and in 3/25 lizards (12.0%); all fecal samples tested negative for the presence of Giardia cysts. Molecular characterization based on nested PCR amplification and sequencing of the SSU-rRNA gene, revealed the presence of Cryptosporidium serpentis in three samples from snakes (Boa constrictor constrictor, Elapheguttata guttata guttata and Python molurus).
Résumé
Afin de déterminer la prévalence et l’identification par génotypage des infections à Cryptosporidium chez les lézards et les serpents, animaux de compagnie, une enquête a été menée en Italie du sud sur 150 reptiles. Les échantillons fécaux ont été conservés dans du formol à 5 % et analysés à l’aide d’un test d’immunofluorescence (IF) du commerce, permettant la détection simultanée d’oocystes de Cryptosporidium et de kystes de Giardia. L’IF a montré la présence d’oocystes de Cryptosporidium dans neuf des 150 échantillons examinés (6,0 %), plus précisément chez 6/125 serpents (4,8 %) et 3/25 lézards (12,0 %). Tous les échantillons ont été négatifs pour la recherche des kystes de Giardia. La caractérisation moléculaire, basée sur l’amplification par PCR nichée et séquençage du gène SSU-rRNA a identifié C. serpentis dans trois échantillons fécaux de serpents (Boa constrictor constrictor, Elaphe guttata guttata et Python molurus).
