| multilocus genotyping of giardia duodenalis in lambs from spain reveals a high heterogeneity. | fecal specimens from 120 lambs in valencia (spain) were analyzed for giardia duodenalis by ifa and nested-pcr using the beta giardin (bg), glutamate dehydrogenase (gdh), triose phosphate isomerase (tpi) and small subunit ribosomal rna (ssurrna) genes. the highest prevalence was obtained using the ssurrna gene (89.2%), whereas values from other techniques ranged from 64.1% to 69.2%. sequences of the ssurrna showed a high proportion of assemblage a or mixed assemblage a/e samples (55.1% and 25.2%, ... | 2012 | 22261115 |
| occurrence and genetic characterization of giardia duodenalis from captive nonhuman primates by multi-locus sequence analysis. | giardia is the most common enteric protozoan that can be pathogenic to both humans and animals. transmission can be direct through the faecal-oral route, or through ingestion of contaminated water or food. genetic characterization of giardia duodenalis isolates has demonstrated the existence of seven groups (assemblages a to g) which differ in their host distribution. assemblages a and b are present in humans and other primates, dogs, cats, rodents, and other species of wild mammals, but the rol ... | 2011 | 21327988 |
