| [q fever. a familial outbreak of 5 cases]. | five cases of acute q fever diagnosed in the same family are reported. the epidemiological and clinical features, the therapy and evolution of the infections by coxiella burnetti are discussed. q fever is a condition to be considered in febrile illnesses or atypical pneumonia, particularly when developing in outbreaks. it is concluded that q fever should be considered as endemic in some areas of this country (basque country, catalonia...). finally, we think that antibiotic therapy (tetracyclines ... | 1990 | 2129681 |
| q fever pneumonia: a review of 164 community-acquired cases in the basque country. | one hundred and sixty four cases of q fever pneumonia are reviewed. coxiella burnetti is responsible for 18.8% of pneumonias acquired in the community in our region with an extremely high seasonal variation. 91% of the cases occur between january and june. 88.5% of the patients are less than 40 yrs of age and 77% are male. the most common clinical symptoms are high fever, cough, cephalalgia and myalgias. 46.5% of the patients have no respiratory symptoms although 34% of the cases report pleural ... | 1989 | 2731605 |
| q fever: prevalence of antibodies to coxiella burnetii in the basque country. | the aim of this study was to ascertain the prevalence of coxiella burnetii infection in the basque population. to this end a stratified sampling was carried out taking as a criterion the size of the population in a given area of residence. residents in sparsely populated areas were found to have a prevalence of 38.5%, significantly greater than in highly populated areas (odds ratio [or] = 1.56; 95% confidence interval [ci]: 1.08-2.27 and or = 1.58; 95% ci: 1.09-2.30). the prevalence was signific ... | 1993 | 8144303 |
| tick-borne zoonotic bacteria in wild and domestic small mammals in northern spain. | the prevalence and diversity of tick-borne zoonotic bacteria (borrelia spp., anaplasma phagocytophilum, coxiella burnetii, and spotted fever group rickettsiae) infecting 253 small mammals captured in the basque country (spain) were assessed using pcr and reverse line blot hybridization. trapping sites were selected around sheep farms (study 1, 2000 to 2002) and recreational parks (study 2, 2003 to 2005). the majority of the studied mammals (162) were wood mice (apodemus sylvaticus), but six othe ... | 2007 | 17693556 |
| prevalence of tick-borne zoonotic bacteria in questing adult ticks from northern spain. | a total of 691 questing adult ixodid ticks of the genera ixodes, haemaphysalis, dermacentor, and rhipicephalus were tested by polymerase chain reaction (pcr) and reverse line blot (rlb) for the presence of anaplasma phagocytophilum, coxiella burnetii, borrelia spp., and spotted fever group (sfg) rickettsiae. ticks were collected by blanket dragging during 2 sampling years (2003-2005) in 10 recreational areas in the basque country (northern spain). adult ticks were collected every month of the ye ... | 2008 | 18759563 |
| short communication: investigation of coxiella burnetii occurrence in dairy sheep flocks by bulk-tank milk analysis and antibody level determination. | to estimate the prevalence of coxiella burnetii in the dairy sheep population from the basque country (northern spain), a study was carried out combining molecular and serological techniques. first, bulk-tank milk samples from 154 flocks belonging to the latxa breed farmers association were analyzed by pcr, with 22% of flocks testing positive for c. burnetii. then, a selection of 34 flocks (7 pcr positive and 17 negative) was investigated for the presence of serum antibodies by elisa test on 1,0 ... | 2009 | 19307639 |
| molecular investigation of the occurrence of coxiella burnetii in wildlife and ticks in an endemic area. | at present few studies have been carried out on the distribution and incidence of coxiella burnetii infection in wildlife. therefore, the aim of this study was to investigate the distribution of c. burnetii in the main wild species in the basque country (northern spain), such as carnivores, cervids, wild boar, lagomorphs and several species of birds. tissues from a total of 601 animals and 340 adult ticks collected from them were analyzed by pcr. dna of c. burnetii was detected in 5.1% of roe de ... | 2011 | 20580169 |
