Recurrent Neurobrucellosis in a Feral Swine Hunter

Brucellosis is a zoonotic infectious disease caused by the bacterial genus Brucella and is most commonly transmitted to humans globally via the consumption of contaminated unpasteurized products. In a significant minority of cases, Brucella has been found to be transmitted by contact with infected swine bodily fluids such as blood. Only a small proportion of all cases of brucellosis affects the central nervous system, and of the four species of Brucella that are known to infect humans, Brucella suis is unusual. Neurologic involvement occurs in a limited proportion of cases and can vary in presentation, ranging from encephalitis to radiculitis or from brain abscess to neuritis. In this case report, we present a 20-year-old male with an eight-day history of headache and neck pain and a high fever that started two days after the onset of the headaches. Three weeks prior, he had hunted, killed, butchered, cooked, and eaten a wild boar in the field. A workup was performed, and blood cultures eventually grew Brucella suis. Although an intensive broad-spectrum antibiotic protocol was implemented, his post-therapy course was complicated. He eventually discontinued his antibiotics after one year.
