The prevalence of antibodies to <jats:italic>Rickettsia conorii<\/jats:italic> in human beings and dogs in the region of Vall\u00e8s Occidental (Catalonia) was assessed by indirect immunofluorescence, and the results compared with those obtained in a similar study from 1987. Nineteen (5\u00b70%) out of 383 human serum samples had antibodies to <jats:italic>R. conorii<\/jats:italic>. This seroprevalence was significantly lower (11\u00b75%) (<jats:italic>P<\/jats:italic> = 0\u00b7003) than that recorded in the 1987 survey. Forty-two out (42\u00b70%) of 100 canine serum samples had antibodies to <jats:italic>R. conorii<\/jats:italic>. A high proportion of the studied dogs (91\u00b70%) were receiving anti-tick treatment, mainly with permethrin-imidacloprid spot-on (Advantix, Bayer, Germany). The current canine seroprevalence was not significantly different from that recorded in the 1987 survey (36.9%). In conclusion, this study shows a significant decrease in the prevalence of antibodies to <jats:italic>R. conorii<\/jats:italic> in the human population of Catalonia in the last 20 years, which corresponds with a decrease in the number of cases of MSF. We suggest that the widespread use of anti-tick treatment in dogs could limit the introduction of ticks to humans due to a reduction of infestation duration in dogs, thus contributing to the decrease in MSF incidence.<\/jats:p>","DOI":"10.1017\/s0950268816000261","type":"journal-article","created":{"date-parts":[[2016,2,22]],"date-time":"2016-02-22T11:43:10Z","timestamp":1456141390000},"page":"1889-1894","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":14,"title":["Prevalence of antibodies to <i>Rickettsia conorii<\/i> in human beings and dogs from Catalonia: a 20-year perspective"],"prefix":"10.1017","volume":"144","author":[{"given":"E.","family":"ESPEJO","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"ANDR\u00c9S","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"P\u00c9REZ","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"PRAT","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"GUERRERO","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
