All of them showed different combinations of the following lesions: fibrinous coelomitis, multifocal necrotizing hepatitis, nephritis and renal hemorrhages, pericarditis, pneumonia, cutaneous lesions, cellulitis, and arthritis.<!--more--> Also, in some of the carcasses, the sciatic nerves had a yellowish coloration and they appeared increased in size.<\/p>\n<p>The inspectors believed that all the findings were compatible with a <strong>colibacilosis<\/strong>, but they wanted to rule out concomitant infections, such as a salmonellosis or a Marek&#8217;s disease. Therefore, they submitted 9 of these carcasses to SESC.<\/p>\n<p>At necropsy, the following lesions were observed:<\/p>\n<ul>\n<li>Hepatitis, necrotizing, suppurative and multifocal (in all 9 animals)<\/li>\n<li>Pericarditis, fibrinous and suppurative (in 6 animals)<\/li>\n<li>Lymphoid depletion in the bursa of Fabricius (in 6 animals)<\/li>\n<li>Enteritis, lymphoplasmacytic\/ granulomatous (in 2 animals)<\/li>\n<li>Pulmonary edema and congestion (in 2 animals)<\/li>\n<li>Lymphoplasmacytic meningoencephalitis (in 1 animal)<\/li>\n<li>Dermatitis, fibrinous and necrotizing (in 1 animal)<\/li>\n<\/ul>\n<p>The lack of microscopic lesions compatible with Marek&#8217;s disease allows ruling out the participation of this viral agent.<\/p>\n<p>Additionally, a microbiological study was performed from the 5 fresher carcasses. In 2 of them a pure growth of <em>E. coli <\/em>was obtained from all the samples submitted (liver, spleen, kidney and celomic swab), while in the other two, apart from <em>E. coli<\/em>, colonies of <em>Aeromonas veronii <\/em>were also obtained. These results confirm that <strong><em>E. coli wa<\/em>s the main causative agent<\/strong>, although the participation of <em>Aeromonas veronii <\/em>cannot be confirmed. The bibliography regarding <em>Aeromonas<\/em> spp. describes its potential as a septicemia causative agent, although also states that it frequently contaminates carcasses during its processing, which cannot be ruled out in this case. Bacteria of the genera <em>Salmonella<\/em> could not be isolated in any of the cases.
