| coprological study of the dicrocoelium dendriticum (digenea) egg elimination by cattle in highland areas in león province, northwest spain. | dicrocoelium dendriticum egg output in cattle from five locations of the porma river basin (león province, northwest spain) was studied at monthly intervals between march 1986 and march 1987. we found d. dendriticum eggs in 37.64% of the 1251 samples examined, and the number of eggs per gram (epg) ranged from 10 to 1000 (average, 41.65 +/- 2.73). the main egg-elimination period, for prevalence, was autumn-winter. the average epg values were quite similar during all months except march, when the ... | 1993 | 8415564 |
| [m129v prnp gene polymorphism in castilla y león shows a similar distribution to other spanish regions and other european countries]. | it has been reported that the polymorphism m129v in the prnp gene modifies the phenotype in all the subtypes of prion diseases in humans. all cases diagnosed to date as suffering the human variant of mad cow disease (vcjd) carry the allele 129m. in the last five years five cases of vcjd have been reported in spain, three of them in castilla y león (in western spain). observation of differences in the genotypic frequency of this polymorphism in different populations prompted us to analyze the dis ... | 2010 | 20004419 |
| a simulation model for the potential spread of foot-and-mouth disease in the castile and leon region of spain. | a spatial stochastic model was used to simulate the spread of a foot-and-mouth disease (fmd) epidemic in the castile-and-leon (cyl) region of spain. the model was fitted using information available on premises demographics and on assumptions for animal movements, indirect contacts, and airborne exposure. control measures dictated by spanish and european union regulations constituted a reference strategy to which six alternative control strategies were compared. for the reference strategy, the me ... | 2010 | 20579754 |
| field and experimental studies on dicrocoelium dendriticum and dicrocoeliasis in northern spain. | the transmission, control and the relationship between dicrocoelium dendriticum and its definitive (sheep and cattle) and intermediate (molluscs and ants) hosts under natural and experimental conditions are described. eleven species of molluscs and four of ants were found infected with larval d. dendriticum in león province, north-west spain. infected ants were observed between april and november and in tetania at 7.5-26.9 degrees c. the highest shedding of eggs by sheep and cattle was detected ... | 2005 | 16336711 |
| susceptibility of planorbarius metidjensis from portugal and spain to schistosoma bovis from salamanca, spain. | the susceptibility of planorbarius metidjensis from portugal and salamanca (spain) to schistosoma bovis from salamanca was studied. the degree of susceptibility as measured by positivity rate, number of cercariae, pre-patent period and survival rate, showed that p. metidjensis from portugal and spain are very susceptible to s. bovis from salamanca. the role of p. metidjensis as a host of s. haematobium is questioned and further studies are shown to be necessary. to determine if the disease exist ... | 1977 | 904368 |
| prevalence of ectoparasitic arthropods on wild animals and cattle in the las merindades area (burgos, spain). | this paper reports the prevalence of ectoparasitic arthropods in sampled groups of wild (n = 128; 16 species) and domestic (n = 69; 3 species) animals in the las merindades area of the province of burgos, spain. the study revealed that wild animals were more infested and with a wider variety of ectoparasites than domestic animals. the parasitic prevalence was 67% for wild animals and 48% for livestock. in this way, 39% of animals were infected by ticks. ixodes ricinus and ixodes hexagonus were t ... | 2011 | 21894267 |
| ticks of the province of salamanca (central/nw spain). prevalence and parasitization intensity in dogs and domestic ungulates. | by sporadic examination of 492 wild animals and regular weekly checks of dogs (179), cattle (288) and sheep and goats (141), 13 ixodides were identified in the province of salamanca. some of these were only detected on the northern (i. ricinus) or southern (h. lusitanicum and b. annulatus) slopes of the mountains to the south of the province. except for occasional introductions, h. lusitanicum and b. annulatus are not found on the castillian plateau. in wild animals, 12 species were found of whi ... | 1986 | 3706991 |

| dynamics of elimination of the eggs of fasciola hepatica (trematoda, digenea) in the faeces of cattle in the porma basin, spain. | in order to contribute to the knowledge of the epizootiological conditions in which fasciolosis develops in the león mountains, the elimination of fasciola hepatica eggs in 10% of the total number of cattle (1301 samples) at five locations in the porma river basin was recorded at monthly intervals between march 1986 and march 1987. the parasite was found in cattle [29.5% prevalence, average of 51.6 +/- 4.5 eggs g-1 (e.p.g.) faeces] throughout the year. the main egg elimination period was winter- ... | 1989 | 2588469 |
| characterization of adult dicrocoelium dendriticum by isoelectric focusing. | water soluble extracts of 3131 adult specimens of dicrocoelium dendriticum from cattle, sheep and goats, mainly from león province, were analysed by isoelectric focusing in thin-layer polyacrylamide gels. activity of the following enzymes was studied: lactate dehydrogenase (ldh, ec 1.1.1.27), glucose phosphate isomerase (gpi, ec 5.3.1.9), phosphoglucomutase (pgm, ec 2.7.5.1), acid phosphatase (acp, ec 3.1.3.2), alpha-glycerophosphate dehydrogenase (alpha-gpdh, ec 1.1.1.8), hydroxybutyrate dehydr ... | 1998 | 9687590 |
| evaluation of the sensitivity and specificity of bovine tuberculosis diagnostic tests in naturally infected cattle herds using a bayesian approach. | test-and-slaughter strategies have been the basis of bovine tuberculosis (bt) eradication programs worldwide; however, eradication efforts have not succeeded in certain regions, and imperfect sensitivity and specificity of applied diagnostic techniques have been deemed as one of the possible causes for such failure. evaluation of tuberculosis diagnostic tools has been impaired by the lack of an adequate gold standard to define positive and negative individuals. here, a bayesian approach was form ... | 2011 | 21890284 |

| echinococcus granulosus infection in spain. | cystic echinococcosis (ce) caused by the cestode echinococcus granulosus is an endemic disease in spain. although specific control programmes initiated in the 1980s have led to marked reductions in ce infection rates in spain, the disease still remains an important human and animal health problem in many regions of the country. human incidence and livestock (including sheep, cattle, pigs and horses) prevalence data were gathered from national epidemiological surveillance information systems and ... | 2008 | 18331519 |
| course of antibiotic sensitivities in escherichia coli and staphylococcus aureus from animals. | in order to establish the evolution of resistance against the common antibiotics from the beginning of their use up to the present time, the sensitivity of escherichia coli isolated from the cecum of wild boars was determined. the mic's of e. coli from these animals in a zoological garden was examined for comparison. the samples from the wild boars were collected in five forests in the belgian ardennes. the mic's obtained (table 1) are comparable to the mean values given in the early literature ... | 1979 | 397700 |
| epidemiologic study of dermatophytoses in salamanca (spain). | an epidemiologic study of the dermatophytoses in salamanca (spain) from 1973 to 1976 was performed. dermatophyte species were identified in 224 patients with clinical tinea infections; 31 bovines, 18 rodents and 70 soil samples. the prevalence of trichophyton verrucosum and epidermophyton floccosum was strikingly high in relation to other statistics. the most common clinical forms were tinea corporis and tinea cruris. tinea capitis by anthropophilic species was uncommon. | 1979 | 542885 |
