CLINICAL AND PATHOLOGIC PRESENTATIONS OF YERSINIOSIS IN VARIOUS NONDOMESTIC SPECIES: AN INVESTIGATION OF OUTBREAKS FROM FOUR NORTH AMERICAN ZOOLOGICAL INSTITUTIONS.

Yersiniosis due to can be associated with high morbidity and mortality in various species and has been a cosmopolitan management challenge in zoological institutions. This gram-negative, environmental bacterium thrives in cold, wet conditions and poses a risk to zoo species. Outbreaks can be costly and impact conservation efforts through loss of threatened and endangered species.

Pharmacokinetics and sedative effects of single-dose oral gabapentin in cheetahs (Acinonyx jubatus).

Objective: To assess the pharmacokinetics and sedative effects of a single administration of oral gabapentin in African cheetahs (Acinonyx jubatus) at 2 different dosages.

Methods: Adult cheetahs (n = 16) located at 3 different zoological institutions were prospectively enrolled to receive single doses of gabapentin administered at 2 different dosages (10 mg/kg and 20 mg/kg). Venipuncture was performed under behavioral restraint at predetermined time points over a 24-hour period using a sparse sampling model.

INVESTIGATING BLOOD LACTATE CONCENTRATION AS A PROGNOSTIC INDICATOR FOR BIRDS PRESENTING WITH BREVETOXICOSIS: 2020-2021.

Large blooms of the dinoflagellate cause annual harmful algal bloom events, or "red tides" on Florida's Gulf Coast. Each year, the Clinic for the Rehabilitation of Wildlife (CROW) is presented with hundreds of cases of aquatic birds that exhibit neurologic clinical signs due to brevetoxicosis. Double-crested cormorants () are the most common species seen, and typically present with a combination of ataxia, head tremors, knuckling, and/or lagophthalmos.

DETERMINATION OF SPECIFIC ENTEROPATHOGEN PRESENCE IN CAPTIVE CHEETAHS () FED VARIOUS DIETS USING FLUORESCENCE IN SITU HYBRIDIZATION.

Chronic enteropathies pose an important difficulty in the captive management of cheetahs () because of suspected multifactorial pathogenesis and the complex nature of enteric microbiota dynamics. Enterobacteriaceae, spp., , spp.

Management of intertarsal septic arthritis in an ostrich (Struthio camelus).

A 7-year-old female ostrich (Struthio camelus) presented with lameness, left intertarsal joint swelling and a healing wound on the caudomedial aspect of the joint. Synovial culture revealed Corynebacterium species and radiographs were consistent with progressive septic arthritis. Multiple treatments were attempted including through-and-through joint lavage, intra-articular antibiotics, caudomedial arthrotomy, and regional limb perfusion in conjunction with systemic antibiotics and analgesia.

Systemic phaeohyphomycosis in splitnose rockfish (Sebastes diploproa) caused by Devriesia sp.

A novel pathogen was documented after two wild-caught, juvenile, splitnose rockfish presented with buphthalmia, grey corneal endothelial plaques and evidence of uveitis. Cytologic evaluation of ocular contents revealed fungal hyphae. Histologic evaluation identified multiple fungal granulomas and granulomatous inflammation in the globes, periocular tissue and heart.

Detection of bacterial-reactive natural IgM antibodies in desert bighorn sheep populations.

Ecoimmunology is a burgeoning field of ecology which studies immune responses in wildlife by utilizing general immune assays such as the detection of natural antibody. Unlike adaptive antibodies, natural antibodies are important in innate immune responses and often recognized conserved epitopes present in pathogens. Here, we describe a procedure for measuring natural antibodies reactive to bacterial antigens that may be applicable to a variety of organisms.
