The histopathological study revealed lesions of\u00a0multifocal subacute severe<strong>\u00a0embolic-metastatic necrotizing p<\/strong> <strong>neumonia\u00a0<\/strong> with the presence of <strong>intralesional bacteria<\/strong>. The black colour was due to areas of <strong>haemorrhage<\/strong> surrounding these inflammatory lesions. The whitish caseous center corresponded to necrosis.<\/p>\n<p>The primary origin of the infection is unknown, a possibility is that it was the skin lesion but no skin samples were available for characterization. Another option would be bacterial endocarditis on the atrioventricular valves, in any case the pattern of injury distribution indicates hematogenic dissemination, therefore, it should be considered as a generalized disease.<\/p>\n<div id=\"attachment_3477\" style=\"width: 460px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-3477\" class=\"size-large wp-image-7619\" src=\"https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-1-scaled-450x600.jpg\" alt=\"\" width=\"450\" height=\"600\" srcset=\"https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-1-scaled-450x600.jpg 450w, https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-1-scaled-225x300.jpg 225w, https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-1-scaled-768x1024.jpg 768w, https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-1-scaled-1152x1536.jpg 1152w, https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-1-scaled-1536x2048.jpg 1536w, https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-1-scaled.jpg 1920w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" \/><p id=\"caption-attachment-3477\" class=\"wp-caption-text\">Black nodular lesions of widespread distribution in the pulmonary parenchyma.<\/p><\/div>\n<div id=\"attachment_3478\" style=\"width: 460px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-3478\" class=\"size-large wp-image-7621\" src=\"https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-2-450x600.jpg\" alt=\"\" width=\"450\" height=\"600\" srcset=\"https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-2-450x600.jpg 450w, https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-2-225x300.jpg 225w, https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-2-768x1024.jpg 768w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" \/><p id=\"caption-attachment-3478\" class=\"wp-caption-text\">Detail of the lesions, a pale coloured center can be observed in some of them (arrowhead).<\/p><\/div>\n<div id=\"attachment_3479\" style=\"width: 630px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-3479\" class=\"size-large wp-image-7623\" src=\"https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-3-678x600.jpg\" alt=\"\" width=\"620\" height=\"549\" srcset=\"https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-3-678x600.jpg 678w, https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-3-300x266.jpg 300w, https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-3-768x680.jpg 768w\" sizes=\"auto, (max-width: 620px) 100vw, 620px\" \/><p id=\"caption-attachment-3479\" class=\"wp-caption-text\">Black skin lesions on the posterior right limb.<\/p><\/div>\n<div id=\"attachment_3475\" style=\"width: 630px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-3475\" class=\"size-large wp-image-7615\" src=\"https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-4-800x600.jpg\" alt=\"\" width=\"620\" height=\"465\" srcset=\"https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-4-800x600.jpg 800w, https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-4-300x225.jpg 300w, https:\/\/sesc.cat\/wp-content\/uploads\/2017\/10\/SESC-066-17-4-768x576.jpg 768w\" sizes=\"auto, (max-width: 620px) 100vw, 620px\" \/><p id=\"caption-attachment-3475\" class=\"wp-caption-text\">Inflammatory lesion with the presence of bacteria and a necrotic center (lighter pink colour) and surrounded by hemorrhage (reddish colour).<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>In a 6-month-old, cross-breed pig carcass, multiple small well-defined black nodules were observed, some of them with a whitish center, distributed throughout the whole lung parenchyma.
