Using minimum inhibitory concentration values of common topical antibiotics to investigate emerging antibiotic resistance: A retrospective study of 134 dogs and 20 horses with ulcerative keratitis.

Objectives: To identify the minimum inhibitory concentration (MIC) distribution for commonly used topical antibiotics from isolates of dogs and horses with ulcerative bacterial keratitis, and to investigate changes in MIC values over time and following treatment with topical fluoroquinolones.

Animals Studied: One hundred thirty-four client-owned dogs and 20 client-owned horses with bacterial ulcerative keratitis.

Procedure: Minimum inhibitory concentration values for 14 topical antibiotics were reported for canine and equine cases of bacterial ulcerative keratitis between 2013 and 2018.

The effects of subconjunctival bupivacaine, lidocaine, and mepivacaine on corneal sensitivity in healthy horses.

Objective: To compare the efficacy and duration of effect of three local anesthetics on corneal sensitivity when administered subconjunctivally in horses.

Animals Studied: Eight healthy adult horses.

Procedure: A randomized, masked, crossover study design was used, with a two-week washout period between trials.

Causes and outcomes of dogs presenting with hyphema to a referral hospital in Colorado: a retrospective analysis of 99 cases.

Objective: To investigate the causes of hyphema in dogs and identify factors associated with poor visual outcomes.

Animals Studied: Ninety-nine dogs (120 eyes) that presented with hyphema.

Procedure: Medical records from the Colorado State University Veterinary Teaching Hospital between the years 2004-2015 were reviewed.

BLOOD GAS, LACTATE, AND HEMATOLOGY EFFECTS OF VENIPUNCTURE TIMING AND LOCATION AFTER MIST-NET CAPTURE OF MOURNING DOVES (ZENAIDA MACROURA), BOAT-TAILED GRACKLES (QUISCALUS MAJOR), AND HOUSE SPARROWS (PASSER DOMESTICUS).

Venous blood gas partial pressures, pH, bicarbonate and lactate concentrations, packed cell volume, white blood cell differential counts, and heterophil/lymphocyte ratios were measured from Mourning Doves (Zenaida macroura), Boat-tailed Grackles (Quiscalus major), and House Sparrows (Passer domesticus). Birds were bled promptly after mist-net capture and banding or following a targeted delay of 45-60 min, in order to assess the impacts of a brief holding period commonly practiced in large-scale bird banding operations. Additionally, effects of venipuncture location (basilic [=ulnar] vein versus jugular vein) were evaluated in male Boat-tailed Grackles sampled promptly after capture and banding.

Causes of endogenous uveitis in cats presented to referral clinics in North Carolina.

Objective: To investigate the causes of endogenous uveitis in cats presenting to referral ophthalmology clinics in North Carolina.

Procedure: Medical records of cats diagnosed with endogenous uveitis at North Carolina State University's College of Veterinary Medicine (NCSU-CVM) or Animal Eye Care Associates of Cary, NC between 2003 and 2015 were reviewed. Inclusion criteria were cats that had complete diagnostic workups, including clinical, clinicopathological, serological, and histopathological data, as well as imaging modalities.
