Abstract

Captive nonhuman primates frequently experience bite wounds inflicted by conspecifics; however, few studies evaluate wound management in these animals. This study evaluates bite wound management in 35 captive ring-tailed lemurs (RTL, Lemur catta) held within five British zoological institutions between 2015 and 2019. Treatments for 152 bite incidents resulting in 211 bite wounds were summarized. Treatment efficacy and potential risk factors for bite wound complications were evaluated for correlations with outcomes. Treatments in the first 48 hours included analgesia alone (54/152; 35.5%); analgesia and antimicrobials (42/152; 27.6%); no treatment (26/152; 17.1%); analgesia, antimicrobials, and wound management under anesthesia (24/152; 15.8%); and antimicrobials alone (6/152; 3.9%). Poor outcomes were observed in RTL in association with 20.4% of wounds (43/211): signs of pain (SOP) after 48 hours were the most common (30/211; 14.2%), followed by signs of infection (SOI, 16/211; 7.6%), wound dehiscence (7/211; 3.3%), and abnormal function or behavior at day 30 (4/211; 1.9%). Poor outcomes were more likely with severe bite wounds and bite wounds to the hand or limb (thoracic or pelvic, excluding the hand or foot). Specifically, SOP were more likely to be observed with severe wounds and solitary wounds, and SOI were more likely to be observed with wounds not treated with early antimicrobials. When SOI occurred, most resolved with antimicrobial treatment alone. Early analgesia is recommended for RTL with bite wounds. If SOP persist, multimodal analgesia should be administered. Clinicians should consider withholding antimicrobials for RTL with bite wounds of mild and moderate severity until SOI are observed.
