Murine typhus (MT) is a cause of fever of intermediate duration in the south of Spain. Rickettsia typhi has been described as the MT etiological agent. Rickettsia felis produces an infection similar to MT. The aim of the study is to determine their seroprevalence in humans in Catalonia. Antibodies to Rickettsia typhi and Rickettsia felis from 217 serum samples were examined by indirect immunofluorescence assay (IFA). Age, gender, residence area, contact with animals, and occupation were surveyed. Rickettsia typhi and Rickettsia felis seroprevalences were 8.8% and 3.2%, respectively. Rickettsia typhi was present in 7.6% of the samples in urban, 8.5% in semirural, and in 21.4% in rural areas, whereas Rickettsia felis 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 Rickettsia felis seropositivity and age. Our data seem to indicate the presence of Rickettsia typhi and Rickettsia felis in humans in Catalonia.
鼠型斑疹伤寒（MT）是西班牙南部中度持续发热的一个病因。斑疹伤寒立克次体已被描述为MT的病原体。猫立克次体可引发与MT相似的感染。本研究的目的是确定它们在加泰罗尼亚人群中的血清阳性率。通过间接免疫荧光法（IFA）检测了217份血清样本中针对斑疹伤寒立克次体和猫立克次体的抗体。对年龄、性别、居住地区、与动物的接触情况以及职业进行了调查。斑疹伤寒立克次体和猫立克次体的血清阳性率分别为8.8%和3.2%。斑疹伤寒立克次体在城市样本中的占比为7.6%，半农村地区为8.5%，农村地区为21.4%，而猫立克次体在城市样本中的占比为3.5%，半农村地区为1.7%，农村地区为7.1%。观察到的唯一具有统计学意义的关联是猫立克次体血清阳性与年龄之间的关联。我们的数据似乎表明加泰罗尼亚人群中存在斑疹伤寒立克次体和猫立克次体。
