Abstract

Q fever is a zoonotic disease caused by the obligate intracellular pathogen Coxiella burnetii, for which domestic ruminants are the primary source of infection in humans. Herein, we investigated the presence of C. burnetiiin humans, sheep, and goats in the semi-arid region of northeastern Brazil. The presence of anti-C. burnetiiantibodies was surveyed using indirect immunofluorescence assay, and detection of C. burnetiiDNA was performed by polymerase chain reaction (PCR). Anti-C. burnetiiantibodies were detected in 60% of farms, 4.8% of goats, 1.5% of sheep, and 4.5% of human samples. PCR was positive in 18.9% of blood samples, 7.7% of milk samples, and 7.7% of vaginal mucus samples. A DNA sequence of a C. burnetiiDNA sample extracted from the goat vaginal mucus showed 99.2–99.4% nucleotide identity with other strains previously reported in Brazil. These results indicate that C. burnetiiis present in the surveyed area, where it poses a risk to both public and animal health. These findings indicate an urgent need for educative actions to protect population, as well as better training of veterinarians to detect and report Q fever.
