| 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 |
| seroprevalence and risk factors associated with toxoplasma gondii in domestic pigs from spain. | serum samples from 2970 (1400 sows, 1570 fattening) pigs, from 100 farms in the 10 main swine production regions in spain were tested for antibodies against t. gondii by the modified agglutination test (mat). antibodies to t. gondii (mat 1:25 or higher) were detected in 492 pigs (16.6%, 9.7% in fattening pigs and 24.2% in sows). the herd prevalence was 85.0% (95% ci: 78-92) and within-farm prevalence ranged from 2.9% to 92.8% (median=17.6%). statistically significant differences were observed am ... | 2010 | 20601110 |
