Diagnostic Testing for Equine Endocrine Diseases: Confirmation Versus Confusion. Despite there being only 2 common endocrine diseases in horses, pituitary pars intermedia dysfunction (PPID) and equine metabolic syndrome (EMS), diagnosis is still confusing. Failing to consider horse factors and treating based on laboratory results only have caused many animals to receive lifelong drug treatment unnecessarily. Increased plasma ACTH, baseline or TRH stimulated, supports a diagnosis of PPID; however, breed, age, thriftiness, illness, coat color, geography, diet, and season also affect ACTH concentration. Insulin dysregulation, the hallmark of EMS, can result from insulin resis...
A novel selective medium for the isolation of Burkholderia mallei from equine specimens. Burkholderia mallei is a Gram-negative bacterium that causes glanders, a zoonotic disease, especially in equine populations (e.g. horses, donkeys, and mules). B. mallei usually grows slowly on most culture media, and this property makes it difficult to isolate from clinical specimens. One of the problems is that B. mallei is easily overgrown by other bacteria, especially in animal specimens collected from non-sterile sites. The aim of this study was to develop a new selective agar for the laboratory diagnosis of glanders. We formulated a new agar, named BM agar, to enrich B. mallei growth, but...

Development of Rose Bengal test against mallein test for rapid diagnosis of equine glanders. Burkholderia mallei, the etiologic agent of the disease known as glanders. Clinical and bacteriological diagnosis of glanders is difficult in the early stages of the disease. Currently, mallein (allergic hypersensitivity test) is used for the diagnosis of glanders. The mallein test requires an experienced laboratory person and lasts 48Â h. Therefore, in order to quickly diagnose the disease, especially in areas (such as the borders of the country) that cannot be kept animals, new methods should be used to identify the disease. The Rose Bengal is a serological diagnostic test and has been recom...
Is Electrical Nerve Stimulation the Answer for Management of Equine Headshaking? Horses with trigeminal mediated headshaking (TMHS) have a decreased activation threshold of the trigeminal nerve and clinical signs are suspected to be a manifestation of trigeminal neuralgia. Electrical nerve stimulation (ENS) is used for management of neuralgia in humans and appears to work via gate control theory. Use of an equine specific percutaneous ENS program in over 130 TMHS horses has resulted in approximately 50% success return to previous work. Electroacupuncture may also be useful in the management TMHS. Optimization of ENS procedures for TMHS is likely to require a greater unders...

Accuracy Quantification of the Reverse Engineering and High-Order Finite Element Analysis of Equine MC3 Forelimb. Shape is a key factor in influencing mechanical responses of bones. Considered to be smart viscoelastic and inhomogeneous materials, bones are stimulated to change shape (model and remodel) when they experience changes in the compressive strain distribution. Using reverse engineering techniques via computer-aided design (CAD) is crucial to create a virtual environment to investigate the significance of shape in biomechanical engineering. Nonetheless, data are lacking to quantify the accuracy of generated models and to address errors in finite element analysis (FEA). In the present study, rever...
Working under conditions of social vulnerability: Depression among Latina/o immigrant horse workers. The American agricultural industry is heavily reliant on Latina/o workers, yet there is scant understanding regarding the mental health of this population. This gap in the literature is glaring as Latina/o farmworkers are a highly vulnerable group who experience high rates of occupational risks and health hazards. This study is the first, to our knowledge, to examine individual, social and work-related correlates of depression among Latina/o horse workers. Methods: A community survey ( = 225) administered by lay health workers was implemented with Latina/o horse workers who were employed in th...
The synovial fluid proteome differentiates between septic and nonseptic articular pathologies. Articular conditions are common in horses and can result in loss of function, chronic pain and/or inability to work. Common conditions include osteoarthritis, osteochondrosis and synovial sepsis, which can be life-threatening, but despite the high clinical prevalence of these conditions, rapid and specific diagnosis, monitoring and prognostication remains a challenge for practicing veterinarians. Synovial fluid from a range of arthropathies was enriched for low abundance proteins using combinatorial peptide ligand ProteoMinerâ„¢ beads and analysed via liquid chromatography-tandem mass spectrom...

A candidate gene approach identifies variants in SLC45A2 that explain dilute phenotypes, pearl and sunshine, in compound heterozygote horses. Variations in the SLC45A2 gene are responsible for the dilution phenotypes cream and pearl in domestic horses. Cream dilution is inherited in an incomplete dominant manner, diluting only red in the heterozygous state but both red and black pigments when two alleles are present. The pearl dilution is recessive and dilutes only the red and black pigment in the homozygous state or when paired with a cream allele. Horses that inherit one copy of pearl (C ) and one copy of the dominant cream allele (C ) display a dilution phenotype similar to that of homozygous cream, suggesting that pearl is the ...
Genetic evaluation of bovine papillomavirus types detected in equine sarcoids in Poland. Equine sarcoids are the most common neoplasms in horses.
