Abstract
Traits such as shape, size, and color often influence the economic and sentimental value of a horse. Around the world, horses are bred and prized for the colors and markings that make their unique coat patterns stand out from the crowd. The underlying genetic mechanisms determining the color of a horse's coat can vary greatly in their complexity. For example, only two genetic markers are used to determine a horse's base coat color, whereas over 50 genetic variations have been discovered to cause white patterning in horses. Some of these white-causing mutations are benign and beautiful, while others have a notable impact on horse health. Negative effects range from slightly more innocuous defects, like deafness, to more pernicious defects, such as the lethal developmental defect incurred when a horse inherits two copies of the Lethal White Overo allele. In this review, we explore, in detail, the etiology of white spotting and its overall effect on the domestic horse to Spot the Pattern of these beautiful (and sometimes dangerous) white mutations.

[Disease Caused by Filoviruses: An Update].
The Marburg and Ebola viruses belong to the Filoviridae family and are known to cause emerging zoonotic diseases. These viruses have a high case fatality rate and are easily transmissible from person to person, which makes them capable of triggering outbreaks, including in non-endemic regions, and are also considered agents of bioterrorism. This review aims to improve clinical knowledge and the approach to suspected cases of FD. Improved surveillance and preparedness for potential global outbreaks are essential measures to effectively respond to these public health threats and to ensure that healthcare professionals are well-informed and prepared to deal with these diseases.

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.

Clinical characterization of a novel episodic ataxia in young working Cocker Spaniels.
The mean age at clinical onset was 4 months. Signs were acute and included episodic body swaying, titubation, cerebellar ataxia, wide-base stance, and hypermetria, all while mentation remained unaltered. Duration of episodes ranged from 30 minutes up to 24 hours, and their frequency varied from weekly to once every 5 months.

Aseptic protocol breaches are common among veterinary students scrubbing, gowning, and gloving into surgery.
At least 1 aseptic protocol breach (APB) was noted in 46.3% of the 96 procedures observed. The most common mistakes noted were contact of the sterile towel onto nonsterile surfaces (17.7%), contact of the gown with nonsterile surfaces (17.7%), touching sterile objects with bare hands (12.5%), and improper scrubbing technique (17.4%).
