| immunohistochemical approach to the pathogenesis of bovine spongiform encephalopathy in its early stages. | an immunohistochemical and histochemical study was carried out on the brains of nine cases of bse-diagnosed cattle as part of the surveillance plan in catalonia, spain. the animals had no clinical symptoms reported and were thus at early stages of the disease. the first part of the study consisted of a characterization of prp(bse) deposits throughout the encephalon. the behaviour of the different immuno-labelling patterns was analysed and tropism of some patterns towards certain brain areas was ... | 2006 | 16406559 |
| seroprevalence of neospora caninum in non-carnivorous wildlife from spain. | serum samples from 1034 non-carnivorous wildlife from spain were tested for antibodies to neospora caninum by competitive screening enzyme linked immunosorbent assay (elisa) and confirmed by an indirect fluorescent antibody test (ifat). high agreement was observed between results in both techniques (kappa value higher than 0.9). prevalences of n. caninum antibodies positive by both techniques were 11.8% of 237 red deer (cervus elaphus), 7.7% of 13 barbary sheep (ammotragus lervia), 6.1% of 33 ro ... | 2007 | 16962706 |
| evolution of the bse epidemic in catalonia (1990-2015) based on a stochastic model. | a stochastic model was used to estimate the number of bovine spongiform encephalopathy (bse) cases that may have occurred in catalonia (north-east spain) from january 1990 to december 2015. the model allowed the evolution of the unobserved cases to be estimated differentiating the population into two subgroups: (1) livestock slaughtered for human consumption without clinical signs and (2) cattle at increased risk (including fallen stock, clinical suspects, emergency slaughtered cattle and cattle ... | 2010 | 19286404 |
| ostertagia ostertagi antibodies in milk samples: relationships with herd management and milk production parameters in two mediterranean production systems of spain. | the present study analyzed ostertagia ostertagi antibodies by indirect elisa in milk samples in two cattle systems in mediterranean spain to indirectly monitor gastrointestinal nematode (gi) parasitism effects on production. individual samples from 10 animals and the corresponding milk herd samples were collected from 133 herds in girona (intensive management) and 123 herds in minorca (extensive management). both locations showed high and significant positive relationships between average optica ... | 2009 | 19464718 |

| further report on cryptosporidium in barcelona zoo mammals. | the prevalence of fecal shedding of cryptosporidium in 36 primates (21 species and subspecies) and 62 herbivores (36 species and subspecies) housed at the barcelona zoo was studied. cryptosporidial oocysts were found in stool samples of 14 primate, 18 artiodactyla, 2 perissodactyla, and 1 proboscidea species. none of them showed symptoms related to the parasite. neither the sex nor the group condition (alone or in a group) of the animals studied appeared to be correlated with parasitic prevalenc ... | 2000 | 10780741 |
| diversity of bacteroides fragilis strains in their capacity to recover phages from human and animal wastes and from fecally polluted wastewater. | great differences in capability to detect bacteriophages from urban sewage of the area of barcelona existed among 115 strains of bacteroides fragilis. the capability of six of the strains to detect phages in a variety of feces and wastewater was studied. strains hsp40 and ryc4023 detected similar numbers of phages in urban sewage and did not detect phages in animal feces. the other four strains detected phages in the feces of different animal species and in wastewater of both human and animal or ... | 1999 | 10103280 |
