Brucellosis Coinfecting with Liver Hydatid Cyst: Case Report and Literature Review of Zoonoses Coinfection of Human Brucellosis.

Background: Brucellosis is a major global public health problem. Brucellosis usually coinfects with zoonoses because of their similar reservoir and infection routes. Materials and Methods: Here, we present a patient who was diagnosed with coinfecting with liver cyst and brucellosis. Results: A 57-year-old female farmer was hospitalized with right hip joint pain approximately 4 weeks earlier. The patient reported a history of hydatid cysts and a family history of brucellosis. Abdominal computerized tomography and ultrasonography revealed a liver hydatid cyst. The standard agglutination test titer of Wright's test was 1:100. Computerized tomography and magnetic resonance imaging revealed brucellosis hip arthritis. The patient was treated with a combination of doxycycline, rifampicin, and cefotaxime. The symptoms immediately improved. The patient was well and asymptomatic during the 6-month follow-up. We reviewed the literature on other zoonoses superinfection with brucellosis. Conclusion: Brucellosis coinfects with multiple zoonosis organisms and poses a serious health threat to humans. Awareness of possible brucellosis coinfection with other zoonoses, especially professionally exposed persons in endemic regions, is warranted.
