ABSTRACT
O objetivo deste trabalho foi verificar a presença de Brucella abortus e as lesões causadas por esse agente nos anexos fetais e nos fetos de búfalas. Para isso, 20 búfalas em diversos meses de gestação, sorologicamente positivas para brucelose, foram submetidas ao abate sanitário. A idade fetal foi determinada através de exames ultrassonográficos associados à mensuração dos fetos durante a necropsia. Do útero fechado desses animais foram coletadas amostras para histopatologia e qPCR. A partir do segundo mês de gestação foi possível detectar a presença de DNA de B. abortus em líquido amniótico, líquido alantoide e em útero e, a partir do quinto mês, na placenta, coração, baço, rim, pulmão, intestino, fígado e linfonodos dos fetos. Os principais achados anatomopatológicos foram placentite fibrinopurulenta necrótica e endometrite supurativa crônica...
The objective of this study was to detect Brucella abortus and injuries caused by the bacteria in fetal membranes and fetuses. Twenty buffaloes serologically positive for brucellosis were used and subjected to stamping for collection of material from the closed uterus of several months gestation. Fetal age was determined by ultrasound examination and the size of fetuses was measured at necropsy. The samples were subjected to histopathology and qPCR. From the second month of pregnancy on it was possible to detect the presence of B. abortus DNA in amniotic fluid, allantoic liquid and uterus, and from the fifth month on in placenta, heart, spleen, kidney, lung, intestine, liver and lymph nodes of the fetuses. The main pathological findings were fibrinous suppurative necrotic placentitis, and chronic endometritis...

Se presenta el caso de una paciente de 23 años de edad, procedente del Estado Barinas, II gesta, la cual presenta un embarazo gemelar monocorial, donde el primer feto tuvo desarrollo normal y falleció por dificultad respiratoria en el período neonatal y el segundo, fue un feto acardio anceps. Al examinar el feto se observó ausencia de corazón y pulmones, cerebro rudimentario y anomalías de las extremidades. La disección reveló epidermis con abundantes células vacuolizadas, dermis edematosa y ausencia del epiplón mayor. Los genitales externos femeninos estaban bien desarrollados. El examen radiológico mostró un cráneo pequeño, osificación de columna vertebral y anomalías óseas de manos y pies. Se hizo una revisión de la literatura sobre acardia en los últimos 30 años
We presente the case of a 23 year old patient, from Barinas State, II gravida, with a twin monochorial pregnancy, a normal fetus who died for respiratory distress in neonatal period and the other one, was an acardio anceps. The acardius presented absence of heart and lungs, a rudimentary brain, and anomalies of extremities. The dissection showed epidermis with numerous vacuolized cells, edematous dermis and absence of mayor epiploon. The external female genitals were well developed. Radiological screening showed a rudimentary cranium and anomalies of the hands and feet. We reviewed the last 30 years of acardia literature
