study of c. burnetii human and animal seroprevalence in a rural population in madrid community.a pilot study on human seroprevalence of antibodies to c. burnetii in the madrid region, initiated in a small rural population, shows a 15.4% positivity by the indirect immunofluorescence test. an urban sample shows an 8.8% positivity. animal seroprevalence in livestock located in the village under study is 76.6% in caprine and 17.7% in bovine. a high risk epidemiological situation is detected.19892691274

the overwintering of eggs, intramolluscal stages and metacercariae of fasciola hepatica under the temperatures of a mediterranean area (madrid, spain).the survival of embryonated and unembryonated eggs, of snails with mature or immature infection and of metacercariae over the winter of a mediterranean area was analyzed. embryonated eggs were more resistant than unembryonated eggs to cold weather, leaving a residual contamination which was responsible for earlier spring infection of the snail. overwintering was similar in snail populations with both mature and immature infections although the lifespan was shorter in the former. both snail popul ...19947886913
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 ...19968711895
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 ...19989618744
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 ...199910423774
relationship between plant biodiversity and heavy metal bioavailability in grasslands overlying an abandoned mine.abandoned metal mines in the sierra de guadarrama, madrid, spain, are often located in areas of high ecological value. this is true of an abandoned barium mine situated in the heart of a bird sanctuary. today the area sustains grasslands, interspersed with oakwood formations of quercus ilex and heywood scrub (retama sphaerocarpa l.), used by cattle, sheep and wild animals. our study was designed to establish a relationship between the plant biodiversity of these grasslands and the bioavailabilit ...200818246431
seasonal availability of fasciola hepatica metacercariae in a temperate mediterranean area (madrid, spain).in this experiment, conducted over a 3-year period (1988-1990), the seasonal availability of fasciola hepatica metacercariae in a temperate mediterranean area (madrid, central spain) was analysed according to the rhythms of snail infection, the periods of cercarial emission, and the resistance of metacercariae. in this area, snails could be infected from late april to early november. cercarial emission by spring infection started at the beginning of summer and terminated 3-4 weeks later. mid-sum ...19958594843
the overwintering of fasciola hepatica eggs under semi-arid and temperate mediterranean climate (madrid, spain).in this experimental work, conducted over two consecutive years (1988 and 1989), we have analyzed the overwintering possibilities of fasciola hepatica eggs deposited in winter in a semi-arid and temperate mediterranean area (madrid, spain). eggs did not survive for more than a week in faeces at environmental moisture conditions. in contrast, over a 75% of the eggs maintained in permanently wet faeces survived winter temperatures, showing no high mortality until important thermic increment from j ...19921519414
[the consumption of food of animal origin distinct from milk: meat, fish, eggs in the school-age population of the community of madrid. the food consumption and nutritional status of the school-age population of the autonomous community of madrid group].the aim of this study was to assess the intake of foods of animal origin other than milk, as well as their role in the diet of children, in a representative sample of a school-aged population from the community of madrid (caenpe study). a 4 day assessment of the dietary intake was conducted by applying a combination of the methods of 24-hour recall and a written record of the estimated consumption. we studied 2,608 schoolchildren between the ages of 6 and 14 years. the subjects were divided into ...19968830592
