Giardia duodenalisand Cryptosporidiumspp. are gastro-intestinal protozoa known to infect small ruminants. Both protozoa are also considered as a potential public health concern. The objective of this study was to determine their prevalence in lambs and goat kids kept under common Mediterranean dairy husbandry systems and to identify the species and genotypes infecting these small ruminants. In total, 684 faecal samples (429 from lambs and 255 from goat kids) were collected on 21 farms in Greece and examined using a quantitative immunofluorescence assay. G. duodenaliswas detected in 37.3% of the lambs and 40.4% of the goat kids. On all but one of the farms G. duodenaliswas detected. Most samples were typed as a mono-infection with G. duodenalisassemblage E, both on the β-giardin gene and the triose phosphate isomerase gene. Only 10% of samples were typed as mixed assemblage A and E infections. The prevalence of Cryptosporidiumspp. was 5.1% in lambs and 7.1% in goat kids. In total, 8 out of the 14 farms with a sheep flock and 7 out of the 14 farms with a goat flock were positive. Cryptosporidium parvum(subtype IId), C. ubiquitumand C. xiaoiwere identified, the latter especially in goat kids. In conclusion, the results of the present study illustrate that G. duodenalisand Cryptosporidiumspp. occur frequently on both sheep and goats farms. The prevalence of zoonotic genotypes or species was low, indicating a limited but existing risk for zoonotic infections. |
