To establish a reference interval for glomerular filtration rate (GFR) determined by measuring serum clearance of a single IV dose of inulin in clinically normal cheetahs (Acinonyx jubatus) and compare serum symmetric dimethylarginine (SDMA) concentration in cheetahs with GFR.


33 cheetahs housed at 3 institutions.


A single bolus of inulin (3,000 mg/m2) was administered IV, and 5 serial blood samples were collected and analyzed for serum inulin concentration with the anthrone technique. The GFR was estimated with a modified slope-intercept method for the slow component of the serum concentration-versus-time curve. Blood urea nitrogen and serum creatinine concentrations were measured in samples obtained immediately prior to inulin administration, and serum SDMA concentration was measured in stored samples.


Mean ± SD measured GFR was 1.58 ± 0.39 mL/min/kg, and the calculated reference interval was 0.84 to 2.37 mL/min/kg. There were significant negative correlations between GFR and serum creatinine concentration (r = −0.499), BUN concentration (r = −0.592), and age (r = −0.463). Serum SDMA concentration was not significantly correlated with GFR (r = 0.385), BUN concentration (r = −0.281), or serum creatinine concentration (r = 0.165).


A reference interval for GFR in clinically normal cheetahs was obtained. Further evaluation of animals with renal disease is needed to determine whether measuring serum clearance of a single IV dose of inulin is a reliable diagnostic test for early detection of renal disease in cheetahs.

Global and national authorities have not historically approached animal health emergencies through a gendered lens. Yet these events almost certainly have gendered dimensions, such as differential engagement of women or men depending on their culturally accepted or assigned roles for animal care; risk of exposure to zoonoses; and access to emergency resources during response and recovery. Despite the role that gender seems to play with respect to animal health emergencies, little research has been conducted to better understand such dynamics, and little policy has been promulgated to address it in a way that optimizes response while ensuring equitable outcomes. This piece summarizes 3 key themes that emerged from a panel discussion on gender and animal health emergencies at the World Organisation for Animal Health Global Conference on Emergency Management in April 2023. These themes were differential gendered exposure to pathogens; a lack of equitable gender representation in animal health decision-making; and enhancement of pathways for recognizing gender in national and international actions in preparing for, detecting, and responding to animal health emergencies. Beyond increasing opportunities for women to engage in leadership, the animal health and veterinary communities will benefit from connecting practitioners with gender experts to develop more integrative approaches to emergency preparedness and management. Animal health professionals should also advocate for further research to elucidate gender-specific dynamics in human populations in the context of animal emergencies and the promulgation of evidence-based policies. Such transformative efforts will lead to better outcomes for all people who depend on and provide care for animals.
