Capybaras (Hydrochoerus hydrochaeris - Linnaeus, 1766) are large rodents, living in groups11. Herrera EA. Capybara social behavior and use of space: pattern and processes. In: Moreira JR, Ferraz KMPMB, Herrera EA, MacDonald DW. Capybara: Biology, Use and Conservation of an Exceptional Neotropical Species. New York: Springer, 2013. p. 195-207.. When cornered or attacked, they defend themselves using their sharp teeth (Figure 1) 22. Oliveira Vieira C, Bernardes Filho F, Azulay-Abulafia L.

Capybaras in their natural habitat. These animals can settle in urban and peri-urban areas, increas the risk of contact with human beings. In detail, on the right: image of the incisors.
A 25-year-old female from Balneário Camboriú (Santa Catarina State, Brazil) was bitten on the left thigh and scratched on the left lower leg while trying to rescue her dog from a capybara attack during a walk in a forested area (Figure 2). She was successfully rescued, but the dog died two days later.
Deep laceration on the left thigh of the victim, possibily caused by the incisor teeth of a capybara, and several scratches on left leg are visible.
The victim underwent intensive wound cleaning and suturing; she received analgesia, amoxicillin and clavulanate 2g/day for 10 days, and tetanus and rabies vaccinations. She developed an abscess in the left thigh, which was drained. After 25 days, she had scars ranging between 1 and 8 cm. At the proximal part of the left thigh, there was an approximately2.5 cm ulcer in the process of resolution and a 4.0 cm scar in the distal part of the thigh (Figure 3). Wounds and infections caused by wild animals are becoming common today which highlights the need for microbiological studies of oral flora in wild animals and traumatic structures33.
