factors affecting the seroprevalence of toxoplasma gondii infection in wild rabbits (oryctolagus cuniculus) from spain.sera from 456 wild rabbits (oryctolagus cuniculus) collected between 1992 and 2003 from five geographical regions of spain were examined for antibodies to toxoplasma gondii by the modified agglutination test. antibodies to t. gondii were found in 65 (14.2%) wild rabbits. prevalence of infection was significantly higher in samples collected from wild rabbits from catalonia, northeast spain (53.8%), where rabbits lived in forest, compared to other areas (huelva and cádiz, andalucía, south spain; t ...200415325052
high seroprevalence of toxoplasma gondii and neospora caninum in the common raven (corvus corax) in the northeast of spain.in recent years, multiple cases of aggressive behavior of common ravens (corvus corax) have been reported by farmers in catalonia (ne spain), including attacking of newborn animals and consumption of dead foetuses. in the present study, seroprevalence of toxoplasma gondii and neospora caninum was determined from 113 legally trapped and released common ravens. t. gondii antibodies were found in 91 (80.5%; ci 95%:72-87) of 113 sera tested by the modified agglutination test. antibodies to n. caninu ...201121645913
[prevalence of antibodies against toxoplasma gondii, rubella virus, cytomegalovirus and herpes simplex virus in pregnant women of catalonia].a seroepidemiological survey was carried out to evaluate the prevalence of antibodies against toxoplasma, rubella virus, cytomegalovirus (cmv) and herpes simplex virus in pregnant women from catalonia during 1985. the study was carried out in a representative sample of the pregnant women cared for in public and private hospitals from catalonia, which was selected in maternal clinics by random sampling. antibody measurements were carried out with the following techniques: toxoplasma, ifi (positiv ...19892562317
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 ...201020601110
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 ...201020189210
prevalence of toxoplasma gondii antibodies in red deer (cervus elaphus) and other wild ruminants from spain.serum samples from 441 red deer (cervus elaphus) and 161 other wild ruminant species, collected between 1993 and 2005 from six regions of spain were tested for antibodies against toxoplasma gondii by the modified agglutination test (mat). antibodies to t. gondii (mat 1:25 or higher) were detected in 15.6% of red deer. statistically significant differences were observed among sampling sites with seroprevalence in red deer from catalonia (42.2%) being significantly higher compared with other spani ...200616359801
seroprevalence of toxoplasma gondii antibodies in domestic cats from barcelona, spain.cats are important in the epidemiology of toxoplasma gondii infection because they are the only hosts that can excrete the environmentally resistant oocysts. antibodies to t. gondii were determined in serum samples from 220 domestic cats (felis catus) from barcelona, spain, using the modified agglutination test (mat). antibodies to t. gondii were found in 99 (45%) of 220 cats, with mat titers of 1:25 in 26, 1:50 in 57, and > or = 1:500 in 16 cats. seropositivity (mat 1:25 or more) was significan ...200314627161
