Murine typhus (MT) is a cause of fever of intermediate duration in the south of Spain. has been described as the MT etiological agent. produces an infection similar to MT. The aim of the study is to determine their seroprevalence in humans in Catalonia. Antibodies to and from 217 serum samples were examined by indirect immunofluorescence assay (IFA). Age, gender, residence area, contact with animals, and occupation were surveyed. and seroprevalences were 8.8% and 3.2%, respectively. was present in 7.6% of the samples in urban, 8.5% in semirural, and in 21.4% in rural areas, whereas was present in 3.5% in urban, 1.7% in semirural, and 7.1% in rural area. The only statistically significant association observed was that between seropositivity and age. Our data seem to indicate the presence of and in humans in Catalonia.
