Mastitis and death of a Corriedale ewe associated with Mycoplasma spp. infection in Buenos Aires province
Mycoplasma spp. infections are associated with different clinical syndromes in ruminants: mastitis, pneumonia, arthritis, otitis, among others. Nevertheless, case reports of clinical diseases associated with Mycoplasma-infections are scarce in small ruminants of Argentina. Mycoplasma agalactiae and...

| description | Mycoplasma spp. infections are associated with different clinical syndromes in ruminants: mastitis, pneumonia, arthritis, otitis, among others. Nevertheless, case reports of clinical diseases associated with Mycoplasma-infections are scarce in small ruminants of Argentina. Mycoplasma agalactiae and Mycoplasma capricolum are the causal agents of contagious agalactia, an exotic disease in the region. Therefore, strict surveillance of these pathogens is needed. Severe mastitis of a 7-years-old Corriedale ewe in a flock from Buenos Aires province is reported. The affected ewe had delivered twin lambs 15 days before the clinical disease was detected and died. During post mortem examination, supramammary lymphadenomegaly was evident. Mammary gland was enlarged and firm, with cyanotic skin and superficial edema; multiple caseous whitish foci were observed in the mammary parenchyma. Similar caseous foci were observed in the caudal-ventral lobes of the right lung. In the histopathological analysis, chronic multifocal necrotizing severe mastitis and fibrinous bronchopneumonia with multifocal necrosis and fibrinous pleurisy were observed. Mycoplasma spp. was isolated from the mammary gland. Mycoplasma spp. nested-PCR resulted positive in mammary gland and lung. Sequencing analysis confirmed the presence of Mycoplasma arginini and Mycoplasma bovis in mammary gland and lung, respectively. The pathological findings were similar to the described in cases of contagious agalactia, therefore, Mycoplasma speciation was decided in order to discard the presence of this exotic disease. |

Nevertheless, case reports of clinical diseases associated with Mycoplasma-infections are scarce in small ruminants of Argentina. Mycoplasma agalactiae and Mycoplasma capricolum are the causal agents of contagious agalactia, an exotic disease in the region. Therefore, strict surveillance of these pathogens is needed. Severe mastitis of a 7-years-old Corriedale ewe in a flock from Buenos Aires province is reported. The affected ewe had delivered twin lambs 15 days before the clinical disease was detected and died.

Las infecciones con Mycoplasma spp. están asociadas con diferentes cuadros clínicos en rumiantes: mastitis, neumonía, artritis, otitis, entre otros. Sin embargo, existen escasos reportes de cuadros clínicos asociados con estas infecciones en pequeños rumiantes de Argentina. Mycoplasma agalactiae y Mycoplasma capricolum son los agentes causales de la agalactia contagiosa, enfermedad exótica en la región. Entonces, es necesario realizar vigilancia epidemiológica estricta de estos patógenos. Se diagnosticó un cuadro de mastitis severa y muerte en una oveja Corriedale de 7 años de edad, en una majada de la provincia de Buenos Aires. La oveja había parido mellizos 15 días antes que comenzara a manifestar enfermedad clínica y muriera. Durante su necropsia, se observó linfoadenomegalia supramaria, glándula mamaria aumentada de tamaño y firme, con piel cianótica y edema superficial. El parénquima mamario presentaba múltiples focos caseosos blanquecinos. Focos caseosos similares se observaron en el lóbulo caudo-ventral del pulmón derecho. En el análisis histopatológico se observó mastitis necrotizante multifocal severa crónica y bronconeumonía fibrinosa con múltiples focos de necrosis pulmonar y pleuritis fibrinosa. Se aisló Mycoplasma spp. de la glándula mamaria. Mediante nested-PCR, se detectó ADN de Mycoplasma spp. en glándula mamaria y pulmón. Mediante secuenciación se confirmó la presencia de Mycoplasma arginini y Mycoplasma bovis en la glándula mamaria y pulmón, respectivamente. Los hallazgos patológicos fueron similares a los descriptos en casos de agalactia contagiosa, por lo que fue necesario determinar que especies de Mycoplasma estaban presentes para poder descartar la presencia de esta enfermedad exótica.
