The animals showed a severe sinusitis of the infraorbital sinuses accompanied by facial edema, conjunctivitis and nasal discharge. <!--more-->Two heads were submitted, from which swabs were collected. A PCR against <strong><em>Mycoplasma gallisepticum <\/em><\/strong>was performed, with a positive result, and a RT-PCR against avian Metapneumovirus (aMPV) with a negative result.<\/p>\n<p>Thus, a diagnosis of <strong>infectious sinusitis of the turkey<\/strong>\u00a0was confirmed, which is caused by <em>M. gallisepticum<\/em>. This infection produces respiratory disease in broilers, laying hens and turkeys, the latter being more susceptible. It produces:<\/p>\n<ul>\n<li>Congestion and catarrhal exudate in nasal cavity, trachea, bronchi, and air sacs, producing nasal discharge.<\/li>\n<li>Some degree of pneumonia.<\/li>\n<li>In severe and chronic respiratory infections can cause fibrinous airsacculitis and fibrinous pericarditis and perihepatitis, associated with high mortality and condemnations in the slaughterhouse.<\/li>\n<li>The infection is frequently exacerbated by viral infections (aMPV, infectious bronchitis virus\u2026) or complicated by bacterial infections (mainly <em> coli<\/em>) resulting in an increased severity and mortality of the disease. This process is called Chronic Respiratory Disease (CRD).<\/li>\n<li>Turkeys: ocular secretions precede the development of the sinusitis of the infraorbital sinuses, presenting mucoid to caseous exudate.<\/li>\n<li>Chickens: it may cause keratoconjunctivitis, characterized by facial and eyelid swelling, increased lacrimation and conjunctival congestion.<\/li>\n<\/ul>\n<p>In affected flocks, <em>M. gallisepticum<\/em> affects most of the animals, producing respiratory signs in 80-90% of the turkeys, but they do not exhibit sinusitis consistently (1-70% of the animals).
