Epidemiologic, clinicopathologic, and diagnostic findings in pet rabbits with myxomatosis caused by the California MSW strain of myxoma virus: 11 cases (2022-2023).

Objective: To determine epidemiologic features of naturally occurring myxomatosis in domestic rabbits in California and to characterize clinicopathologic and diagnostic findings.

Animals: 11 client-owned rabbits, Oryctolagus cuniculus subsp domesticus.

Clinical Presentation: A prospective study of pet rabbits with myxomatosis seen at an exotic animal specialty clinic in Santa Cruz county, California, was conducted between January 1, 2022, and December 31, 2023.

MILBEMYCIN OXIME (INTERCEPTOR) TREATMENT OF PYCNOGONID SEA SPIDER INFESTATION IN THREE SPECIES OF CORALS.

A coral reef system at the Steinhart Aquarium in San Francisco, CA, USA experienced a population explosion of pycnogonid sea spiders (Arthropoda: Class Pycnogonida) with subsequent deleterious health effects on the corals in the system. Sixteen coral colonies across three species (, , and ) were chosen from this system for milbemycin oxime immersion therapy trials, with the goal of decreasing or eradicating the sea spider population with minimal detrimental effect to the corals. Corals underwent two milbemycin immersion treatments, administered 1 wk apart, at the previously published aquatic invertebrate dose of 0.

Ultrasonographic features of a urinary bladder leiomyoma in a cat.

Case Summary: Leiomyoma of the urinary bladder in cats is infrequently documented in the literature, and a description of the ultrasonographic appearance has never been reported. A 9-year-old female spayed cat presented with a 6-month history of intermittent hematuria and progressive pollakiuria. On abdominal ultrasound, a large ovoid mass of mixed echogenicity was seen originating from the ventral apical bladder wall.

Concurrent bullous emphysema, bronchointerstitial pneumonia with necrosis, and tension pneumothorax in an 8-week-old puppy.

An 8-week-old, male, mixed breed puppy was presented because of progressive respiratory distress. Thoracic radiographs revealed innumerable coalescing pulmonary bullae throughout the lungs with increased soft tissue opacity of the remaining pulmonary parenchyma and tension pneumothorax. Necropsy and histopathological findings were compatible with bullous emphysema and marked neutrophilic to histiocytic bronchointerstitial pneumonia with necrosis, bronchiectasis, fibrosis, dystrophic mineralization, and vasculitis with thrombosis.
