| progress in control of cystic echinococcosis in la rioja, spain: decline in infection prevalences in human and animal hosts and economic costs and benefits. | the autonomous community of la rioja is a region in the north of spain where the mean annual number of surgical cases of cystic echinococcosis (ce) was 50 (19 per 100000 inhabitants) during the years 1984-1987. this high clinical incidence prompted local authorities to implement a control program in 1986, whose methods and results are reported here. initially, the program consisted in documenting the prevalence of ce in sheep and humans, communicating an awareness of the disease risks among the ... | 2002 | 12204394 |
| detection of rickettsia spp. in haemaphysalis ticks collected in la rioja, spain. | in an attempt to know the potential risk of human disease after exposure to ticks in la rioja (north of spain), the objective of our study was to investigate the presence of rickettsia species in haemaphysalis ticks collected in our area. a total of 177 haemaphysalis spp. belonging to three species (h. punctata, h. sulcata, and h. inermis) were subjected to dna extraction and tested by polymerase chain reaction (pcr) targeting three rickettsial genes: glta, ompb, and ompa. six (3 h. inermis, 2 h ... | 2008 | 18454590 |
| 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 |
