Abstract

Most of the natural cases of pneumonia in feedlot cattle are characterized by a longer clinical course due to chronic lung lesions. Microscopically, these lesions include interstitial fibroplasia, bronchitis, bronchiectasis, bronchiolitis obliterans, and epithelial metaplasia of the airways. Herein, the aim was to review, under a medical perspective, the pathologic mechanisms operating in these chronic pneumonic lesions in calves. Based on the similarities of these changes to those reported in bronchiolitis obliterans/organising pneumonia (BO/OP) and chronic obstructive pulmonary disease (COPD) in human beings, calves are proposed as an alternative animal model.

9. Histochemical study of Encephalitozoon cuniculispores in the kidneys of naturally infected New Zealand rabbits

Abstract

Encephalitozoon cuniculiis an important microsporidian pathogen that is considered an emergent, zoonotic, and opportunistic. It infects both domestic and laboratory rabbits, generating severe chronic interstitial and granulomatous nephritis with fibrosis and granulomatous encephalitis. Encephalitozoonosis is diagnosed in paraffin-embedded sections by examining the spores in the host tissues. The spores are difficult to observe when the samples are stained with hematoxylin and eosin (H&E), particularly when there is an inflammatory reaction and tissue damage. The spores are easily mistaken for other microorganisms, such as fungi (yeasts), protozoa, and bacteria. In our study, we used kidney samples from E. cuniculi–positive rabbits and employed 14 recommended histologic stains for detecting microsporidia spores: alcian blue, calcofluor white, Giemsa, Gram, Grocott, H&E, Luna, Luxol fast blue, Masson trichrome, modified trichrome stain (MTS), periodic acid–Schiff reaction (PAS), Van Gieson, Warthin–Starry (WS), and Ziehl–Neelsen (ZN).We concluded that MTS and Gram stain, detected by light microscopy, and calcofluor white stain, detected by ultraviolet light microscopy, are the best stains for detecting spores of E. cuniculiin paraffin-embedded tissues from infected rabbits. These stains were superior to WS, ZN, Giemsa, and PAS for identifying spores without background “noise” or monochromatic interference. Also, they allow individual spores to be discerned in paraffin-embedded tissues. MTS allows observation of the polar tube, polaroplast, and posterior vacuole, the most distinctive parts of the spore.

Abstract

Osteochondrosis (OC) is a term used to describe a wide range of different skeletal lesions between different species. Osteochondrosis is a problem that affects fast growing animals and it has been defined as a failure in the endochondral ossification of the articular-epiphyseal cartilage. This failure leads to cartilage thickening and retention, basal necrosis, subchondral bone damage and loose bone fragments in the articular joint. Osteochondrosis is a multifactorial disease in which nutritional, hereditary, endocrine factors, biomechanical influences, and failures of blood supply to growth cartilage play an important role. The aim of this review is to offer an updated approach to the knowledge of the mechanisms that intervene in the pathogenesis of osteochondrosis, as well as alternatives to its diagnosis and treatment.

Abstract

El término osteocondrosis (OC) se refiere a una gran variedad de lesiones esqueléticas en diferentes especies. La osteocondrosis es un problema que afecta a los animales de rápido crecimiento y se ha definido como una falla en la osificación endocondral del cartílago articular epifiseal. Dicha falla provoca un engrosamiento y retención del cartílago, necrosis basal, daño al hueso subcondral y desprendimiento de fragmentos óseos en la cavidad articular. La osteocondrosis es una enfermedad de etiología multifactorial donde factores nutricionales, hereditarios, biomecánicos, endocrinos, así como la falla en el aporte sanguíneo del cartílago en crecimiento juegan un papel importante. La finalidad de esta revisión es ofrecer un acercamiento al conocimiento de los mecanismos que intervienen en la patogénesis de la osteocondrosis, así como a las alternativas para su diagnóstico y tratamiento.
