| prevalence of agglutinating antibodies to toxoplasma gondii in small ruminants of the madrid region, spain, and identification of factors influencing seropositivity by multivariate analysis. | a seroepidemiological survey of toxoplasma gondii infection in sheep and goats was conducted in the madrid region of spain. sera were collected from 60 herds, for which farming management information and other relevant data for their characterization were also obtained through a questionnaire. the seroprevalence was 11.8% (64 out of 541), using the modified (2-mercaptoethanol) direct agglutination technique with a 1:64 cut-off titre. the relationship between seropositivity and the variables in t ... | 1996 | 8711895 |
| factors associated with seroprevalence to mycobacterium paratuberculosis in small-ruminant farms in the madrid region (spain). | a cross-sectional study was conducted in a population of small ruminants in the madrid region (spain) to determine the mycobacterium paratuberculosis seroprevalence and to identify farm factors possibly associated with paratuberculosis (ptb). farming-management information and sera were collected from 60 sheep or goat flocks. the relationship between seropositivity and the variables in the questionnaire was assessed by unconditional logistic regression, followed by random-effects logistic regres ... | 1998 | 9618744 |
| associations of veterinary services and farmer characteristics with the prevalences of brucellosis and border disease in small ruminants in spain. | we investigated the farm factors associated with the prevalences of brucellosis and border disease (bd) in small-ruminant herds in the madrid region of spain. these infections were used as models of diseases of well-known and totally unknown distribution, respectively, to assess the association between the perception of the importance of a given disease on the relative contributions of veterinary services and the farmer's attitudes to its prevention. sera, farming-management information and data ... | 1999 | 10423774 |
