Author Abstract

Bone marrow cytopathology and histopathology are vital tools for understanding diseases and conditions that affect or arise from the bone marrow.

Archives Highlights:
Case series of maggot debridement therapy demonstrates safety and efficacy for treating problematic wounds in cats and dogs in Mexico.
Treatment was administered by applying 8-10 larvae per square cm surface area directly on the wound bed and covering the wound with a sterile polyester mesh, sutured to the skin. These were left on the wound for cycles of approximately 48 hours (24-72 hours); the cycles were repeated if more than 20% necrotic tissue remained after treatment. Review of these cases revealed that 80% of treated wounds achieved 100% debridement within 48-96 hours of treatment.
Performing an Avian Physical Examination in Practice
As with mammalian physical examinations, it is important to develop a consistent order for the avian examination to thoroughly evaluate each body system. Some components of the physical examination differ between avian species. For example, cloacal palpation is performed in chickens, but not in parrots.
Association between highly pathogenic avian influenza outbreaks and weather conditions in Japan.
We found that higher average air temperatures two to three weeks prior, lower average wind speeds four weeks prior, and longer sunlight hours two and four weeks prior to outbreaks were significantly associated with increased risk of HPAI outbreaks in Japan. These results suggest that weather may influence environmental survival and transmission of the virus, as well as patterns of wild bird movement that could seed new outbreaks.
Effective treatment with afoxolaner (NexGard) of Trixacarus caviae in a pet guinea pig.
The animal was treated with a single oral dose of 2.50 mg/kg afoxolaner, and the lesions, presence/absence of mites, and intensity of pruritus were evaluated periodically until 2 months post-treatment. A week after the medication, the lesions were milder, but pruritus was still present and was attributed to the healing process. Further examinations showed significant improvement with the complete remission of clinical signs and no mites at the microscopic examination after 4 weeks.
Endoparasites of rabbits and hares.
Accurate gross and microscopic identification of endoparasites in rabbits and hares is an important element of the diagnostic work of veterinary anatomic pathologists. Given the zoonotic nature of rabbit and hare endoparasites, such as C. hepatica, E. cuniculi, and others, veterinary pathologists are ideally poised to make valuable contributions to the understanding of the disease ecology of these pathogens in the context of a One Health research program.
