| monitoring bluetongue disease (btv-1) epidemic in southern spain during 2007. | on the 25th of july 2007, bluetongue virus (btv) serotype 1 was detected in andalusia, southern spain for the first time. a total of 4436 farms infected with btv-1 were confirmed during that year: 3162 in sheep flocks, 113 in goat flocks, 7 in cattle herds and 1154 in mixed farms (sheep, goat and/or cattle in the same farm). the most common clinical signs were: fever, depression, lethargy, facial edema, and salivation (observed in more than 70% of the infected farms). lesions in oral mucosa, lam ... | 2010 | 20663576 |
| epidemiological surveillance of bluetongue virus serotypes 1, 4 and 8 in spanish ibex (capra pyrenaica hispanica) in southern spain. | a cross-sectional study was carried out to assess the prevalence and circulation of bluetongue virus (btv) in spanish ibexes (capra pyrenaica hispanica). a total of 770 sera samples, 380 blood samples and 34 spleen samples were collected between 2006 and 2009 in andalusia (southern spain), a region and time period with a wide circulation of btv in livestock. thirty-one out of 770 (4.0%; ci(95%): 2.6-5.4) sera samples analyzed by elisa showed antibodies against btv. twenty-four out of 31 seroposi ... | 2010 | 21111545 |
| role of wild ruminants in the epidemiology of bluetongue virus serotypes 1, 4 and 8 in spain. | abstract: although the importance of wild ruminants as potential reservoirs of bluetongue virus (btv) has been suggested, the role played by these species in the epidemiology of bt in europe is still unclear. we carried out a serologic and virologic survey to assess the role of wild ruminants in the transmission and maintenance of btv in andalusia (southern spain) between 2006 and 2010. a total of 473 out of 1339 (35.3%) wild ruminants analyzed showed antibodies against btv by both elisa and ser ... | 2011 | 21781340 |
| understanding spatio-temporal variability in the reproduction ratio of the bluetongue (btv-1) epidemic in southern spain (andalusia) in 2007 using epidemic trees. | andalusia (southern spain) is considered one of the main routes of introduction of bluetongue virus (btv) into europe, evidenced by a devastating epidemic caused by btv-1 in 2007. understanding the pattern and the drivers of btv-1 spread in andalusia is critical for effective detection and control of future epidemics. a long-standing metric for quantifying the behaviour of infectious diseases is the case-reproduction ratio (rt), defined as the average number of secondary cases arising from a sin ... | 2016 | 26963397 |
| monitoring bluetongue virus vectors in andalusia (sw europe): culicoides species composition and factors affecting capture rates of the biting midge culicoides imicola. | in this work, we summarize the results of captures of culicoides species in andalusia (s spain) during 2007-2008. four out of the 15 midge species-culicoides imicola, culicoides obsoletus complex, culicoides pulicaris complex, and culicoides nubeculosus-accounted for 80.7 % of captures (n = 68,190). captures were seasonal and mostly occurred in may-november. the overall number of culicoides specimens captured and the mean number of caught per trap were higher in 2007. we used an information-theo ... | 2012 | 22610444 |
