To date, no information is available on the prevalence and genetic identity of Cryptosporidium spp. in cattle in Algeria. In this study, 17 dairy farms in the province of Batna, located in the northeast of the country, were visited to collect 132 fecal samples from young calves (< 8 weeks old). Samples were examined microscopically using the modified Ziehl-Neelsen acid-fast staining method, and at least one sample per farm was submitted for molecular analysis. Amplification of a fragment of the small subunit ribosomal RNA gene was positive for 24 of the 61 samples (40%), and sequence analysis identified three species, namely Cryptosporidium bovis (n = 14), C. ryanae (n = 6), and C. parvum (n = 4). The C. parvum IIaA13G2R1 subtype, an uncommon zoonotic subtype, was identified in two isolates from a single farm by sequencing a fragment of the GP60 gene. This is the first report about genotyping and subtyping of Cryptosporidium in calves in Algeria.
Résumé
Actuellement, aucune information n’est disponible sur la prévalence et l’identité génétique de Cryptosporidium spp. chez les bovins en Algérie. Dans ce travail, 17 fermes laitières de la province de Batna, située au nord-est du pays, ont été inspectées pour récolter 132 échantillons fécaux de jeunes veaux (< 8 semaines). Les échantillons ont été examinés microscopiquement en utilisant la méthode de Ziehl–Neelsen modifiée, et au moins un échantillon par ferme a été soumis à analyse moléculaire. L’amplification d’un fragment du gène de la petite sous-unité du RNA ribosomal a été positive pour 24 échantillons parmi 61 (40 %), et l’analyse des séquences a identifié trois espèces, Cryptosporidium bovis (n = 14), C. ryanae (n = 6) et C. parvum (n = 4). Le sous-type IIaA13G2R1 de C. parvum, un sous-type zoonotique peu répandu, a été identifié par séquençage d’un fragment du gène GP60 dans deux isolats d’une seule ferme. Ceci est le premier rapport sur le génotypage et le sous-typage de Cryptosporidium chez les veaux en Algérie.
