| epizootiologic investigations of selected abortive agents in free-ranging alpine ibex (capra ibex ibex) in switzerland. | in the early 2000s, several colonies of alpine ibex (capra ibex ibex) in switzerland ceased growing or began to decrease. reproductive problems due to infections with abortive agents might have negatively affected recruitment. we assessed the presence of selected agents of abortion in alpine ibex by serologic, molecular, and culture techniques and evaluated whether infection with these agents might have affected population densities. blood and fecal samples were collected from 651 ibex in 14 col ... | 2011 | 21719818 |
| prevalence of toxoplasma gondii and neospora caninum antibodies in spanish ibex (capra pyrenaica hispanica). | a cross-sectional study was carried out on spanish ibex populations in southern spain to assess the seroprevalence of toxoplasma gondii and neospora caninum and to investigate the risk factors associated with these infections. using the modified agglutination test, the seroprevalence to t. gondii was 27.5% (146/531; ci(95%), 23.7-31.3), and this seropositivity significantly increased with age. among adults, statistically significant differences were observed between geographical locations and ov ... | 2010 | 21159529 |
| 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 |
