| Summary: | Coxiella burnetii is a multi-host bacterium of major public and animal health concern. This pathogen circulates among several wild species in the Iberian Peninsula, however, the role of the Iberian lynx (Lynx pardinus) in the epidemiology of this emerging pathogen is still unknown. The objective of this work was to assess the circulation of C. burnetii in Iberian lynx populations from the Iberian Peninsula and to study the molecular characterisation of this pathogen in lynxes and their feeding ticks. A total of 922 lynxes, including free-ranging and captive individuals, were sampled between 2010 and 2022 for the collection of sera (n = 543), spleen samples (n = 390) and ticks (n = 357 from 61 lynxes). The overall seroprevalence was 7.7 % (42/543; 95 %CI: 5.5–10.0 %), with age being significantly associated with the C. burnetii exposure in free-ranging lynxes. A longitudinal study was also carried out to assess the dynamics of the circulation of C. burnetii in this wild host, revealing that 7 of the 37 longitudinally surveyed individuals seroconverted during the study period. The PCR prevalence was 4.4 % (17/390, 95 %CI: 2.3–6.4 %) for spleen samples and 1.1 % (4/357; 95 % CI: 0.0–2.2) in ticks. This is the first study to evaluate the circulation of C. burnetii in the Iberian lynx and to confirm the infection in this felid. The results obtained show a moderate, wide, homogeneous, and endemic circulation of this bacterium in the Iberian lynx populations. |
