Objective: To demonstrate an underutilized, reliable, and technically simple anuran venipuncture technique by use of the popliteal sinus.
Animals: Medium to large (> 30 g) anuran species.
Methods: The animal is manually restrained using an encircling grip around the pelvic girdle.
Objective: Evaluate SARS-CoV-2 morbidity, mortality, clinical signs, treatment interventions, and vaccination practices in tigers under professional care.
Animals: Amur (Panthera tigris altaica), Sumatran (Panthera tigris sumatrae), and Malayan (Panthera tigris jacksoni) tigers managed under the Tiger Species Survival Plan (SSP).
Methods: A retrospective, voluntary online survey was sent to all North American zoos holding SSP tigers between January 2020 and June 2023.
Insects are increasingly common in households, zoological collections, research, and food industries. Increased knowledge of insect health parameters is necessary to ensure proper welfare. The study goal was to develop a hemolymph collection technique and report hemolymph serum biochemical parameters for the thorny devil stick insect ().

Immersion overdose in tricaine methanesulfonate (MS-222) is ineffective for euthanasia of adult goldfish (), and investigation of alternative techniques is warranted. This study evaluated potassium chloride (KCl) administered via four routes for goldfish euthanasia. Thirty clinically healthy adult goldfish (17.

Study objectives were to evaluate efficacy of intracardiac potassium chloride (KCl), ivermectin, or lidocaine hydrochloride (HCl) for euthanasia of anesthetized blue crabs (). Twenty adult male crabs ( = 5/group) were immersed in 500 mg/L eugenol for 5 min beyond loss of the righting reflex and then randomly administered intracardiac 10 mEq/kg KCl (333 mg/mL), 5 mg/kg ivermectin (10 mg/ml), 100 mg/kg lidocaine hydrochloride (HCl) (20 mg/ml), or 5 ml/kg saline (0.

Cytology revealed neoplastic lymphocytes and microscopy confirmed dermal infiltration with epitheliotropism in the epidermis, oral mucosa, and cornea, without internal organ involvement. Transmission electron microscopy did not identify viral particles.

Blood (hemolymph) transfusions are a widely used therapeutic tool in other species, but investigation in terrestrial arthropods remains scarce. Study objectives were development and evaluation of a serum transfusion process in the thorny devil stick insect.
