Abstract:
Equine glanders is a severe bacterial disease known since ancient times. Although eradicated in the most part of the world it is now considered re-emerging. Considering very scarce literature data, we used from formalin fixed collection material: nasal septum, lung and skin specimens from naturally infected horses. Tissues were grossly examined and photographed. Tissue samples, after standard processing, were stained with HE, Congo red and Groccot and microscopically examined. Gross changes include nodules and ulcers in the nasal mucosa with granulation and scarring, pyogranulomas in the lung tissue and nodules and ulcers of the skin. Microscopically marked inflammation of affected tissues with neutrophilic and mononuclear infiltration and fibrous tissue proliferation were seen. As a potent zoonotic agent it has been already used as a biological weapon in the past.
