These lesions developed areas of extensive fibrosis\u00a0with\u00a0mineralization or <strong>osseous metaplasia<\/strong> (i.e. bone tissue that is generated in the center of the \u00a0fibrous lesion, which explains the hardness of the lesions found on the carcass).<\/p>\n<p>A series of tests were performed to determine the cause of these inflammatory lesions:<\/p>\n<ul>\n<li>The Ziehl Neelsen staining was unable to determine the presence of mycobacteria. Both PCR and direct mycobacteria culture also gave negative results.<\/li>\n<li>The Gram stain did not allow to observe gram positive bacteria.<\/li>\n<li>Neuther did Groccott&#8217;s stain allow to observe fungal structures.<\/li>\n<\/ul>\n<p>Thus it was not possible to determine the etiology of these lesions probably because of their advanced chronicity preventing to identify the cause.
