Prevalence and genotypes of Giardia duodenalis from dogs in Spain: possible zoonotic transmission and public health importance (original) (raw)

Abstract

The prevalence of Giardia duodenalis was determinate in faecal samples from dogs and cats in Madrid, Spain and molecular characterisation of isolates. A total of 604 and 144 faecal samples from dogs and cats, respectively, were analysed by routine coprological methods. The prevalence of G. duodenalis was 16.4 % (99/604) in dogs and 4.2 % (6/144) in cats. Sixty-four G. duodenalis isolates (63 from dogs and 1 from a cat) were characterised using glutamate dehydrogenase and β-giardin genes by PCR-RFLP. The single cat sample showed a mixed infection by assemblages A + F. The assemblages found in the dog samples were A, B, C, D and E, both as single and as mixed infections. The zoonotic assemblages A and B were found in 56 (88.8 %) _G. duodenalis_-positive samples with 15.9 % of samples having assemblage A (10/63) and 73 % of samples with assemblage B (46/63), indicating high potential zoonotic risk and public health significance.
