| seroprevalence and risk factors associated with toxoplasma gondii infection in pig farms from catalonia, north-eastern spain. | seroprevalence and associated risk factors for toxoplasma gondii infection in pigs were analyzed in 1202 sera samples, including sows and pigs of three, seven, 11, 15 and 20 weeks of age, from 23 farms in catalonia, north-eastern spain. antibodies were tested by the modified agglutination test (mat) at titers > or =1:25. antibodies to t. gondii were found in 228 samples (19.0%; 95% ci: 16.8-21.2). the individual prevalence in animals higher than 7 weeks of age was 22.8% (174/762; 95% ci: 16.6-29 ... | 2010 | 20189210 |
| 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 |
| the impact of csfv on the immune response to control infection. | the severity of the acute form of csf is responsible for the high mortality rate and has been the subject of many studies. nevertheless, some animals are likely to develop a mild, chronic, or unapparent form of the disease. paradoxically, this clinical form of the disease has not been well studied, especially regarding its pathogenesis. in this study, we investigated the infection in domestic pigs that is caused by the csfv cat01 strain, which is responsible for the 2001-2002 csfv outbreak in ca ... | 2014 | 24657786 |
