Popis: | The aim of this paper was to investigate the morphology, localization and typization of abomasal ulcers in high-yielding dairy cows, as a contribution to the existing knowledge on the subject. A total of ten high-yielding dairy cows which died during the period of early puerperium and two Holstein heifers which died in late pregnancy after transport to a new location were investigated in this study. Samples of altered abomasal tissue were taken at necropsy for further histopathology and mycology investigations. The disclosed ulcerations of the abomasums in twelve investigated animals differed among them not only as far as localization and morphology are concerned, but also in the degree of intramural penetration. Such differences distinguished them into four types. Ulcerations of type one and type two, recorded in two heifers and six cows, as well as in one cow with lymphoma of the abomasum. Perforating ulcer of type three, with circumscripted peritonitis was diagnosed in one cow in the corpus of the abomasum close to the curvatura major. An interesting finding was the simultaneous occurrence of type four perforating ulcer and ulcer-type one, which were located next to each other. Histopathological examination of the structure of the ulcerated abomasum dyed with the hematoxylin-eosin method showed that coagulation necrosis in the area of the ulceration revealed a moderate inflammatory infiltrate in the lamina propria. In the cow affected with lymphoma, a copious tumorous lymphoid infiltrate was concurrent. Mycotic ulcerative abomasitis was described in a cow seven days after calving. In these lesions Aspergillus fumigatus and Mucor spp. were isolated. Histopathological analysis of tissue samples dyed with the Grocott method, described septed and nonsepted hyphae in the blood vessels and surrounding tissue of the tunica mucosa and submucosa. |
