Development of an in situ hybridization assay for the diagnosis of Mycobacteriaceae infections of veterinary importance
Investigation published in Veterinary Pathology
Mycobacteria (Mycobacteriaceae family) comprise five genera (Mycobacterium, Mycolicibacterium, Mycolicibacter, Mycolicibacillus, and Mycobacteroides), which include relevant animal and human pathogens. Histology is a rapid method for preemptively diagnosing mycobacteriosis, contributing to surveillance, control, and eradication. A constraint on histology is the limited sensitivity and specificity of acid-fast stains, as the number of detectable bacilli in formalin-fixed paraffin-embedded (FFPE) tissue varies and other microorganisms are acid-fast positive. Immunohistochemistry has low specific…

Histological and Immunohistochemical Characterization of a Histiocytic Sarcoma Associated With a Follicular Lymphoma in a Ring-tailed Lemur (Lemur catta)
Veterinary Medicine and Science publish this investigation article
A 20-year-old neutered male ring-tailed lemur (Lemur catta) diagnosed with an intrathoracic mass died during surgical excision. Morphological characteristics of the mass during necropsy were consistent with a mediastinal abscess in the left hemithorax. Histological examination identified a disseminated histiocytic sarcoma involving spleen, kidneys, multiple lymph nodes, diaphragm and parietal pleura, as well as a concurrent follicular lymphoma in a separate lymph node. A mixed metastatic infiltrate composed of both neoplasms was found within the capsule of the intrathoracic abscess. Immunohist…
