Pericarditis crónica en un loro gris africano (Psittacus erithacus erithacus) causada por Salmonella

espanolSe presento una hembra adulta de loro gris africano, con historial previo de picaje, por un episodio agudo de convulsiones, letargia, anorexia y diarrea. Se instauro inicialmente un tratamiento con calcio, vitaminas, enrofloxacina, fluidoterapia y glucosa, y fue colocada en una jaula de oxigenoterapia durante 5 dias. La bioquimica sanguinea revelo un aumento de AST, acidos biliares y CK, y un descenso moderado de albumina, proteinas totales y sodio. Las radiografias mostraron hepatomegalia. Se anadio silimarina y lactulosa al tratamiento durante 1 mes y, despues de finalizar este, se presento de nuevo con anorexia y letargia, y murio de forma hiperaguda. La necropsia revelo una pericarditis fibrinosa grave, hidroceloma moderado, pulmones enrojecidos y un higado de color verde. Los hallazgos microscopicos consistieron en una pericarditis fibrinosa y necrosupurativa cronica, rabdomionecrosis grave con necrosis fibrinoide y trombosis de arterias intralesionales, celomitis visceral fibrinosa, necrosis hepatica con colestasis hepatocelular grave y neumonia intersticial con atelectasia. Se cultivo Salmonella sp. del exudado pericardico. El caso de salmonelosis aqui descrito resulta inusual, basado en el componente predominante de pericarditis cronica. EnglishAn adult female African grey parrot with a previous history of feather picking was presented with an acute onset of seizures, lethargy, anorexia and diarrhea. Initially, it was treated with calcium, vitamins, enrofloxacin, fluids and glucose, and placed in an oxygen cage for 5 days. Serum chemistries revealed elevated AST, bile acids, and CK, as well as mildly decreased albumin, total protein, and sodium. Radiographs revealed hepatomegaly. It was additionally treated with silymarin and lactulose for 1 month. At the end of treatment, the bird was presented again with anorexia and lethargy, and died peracutely. Necropsy revealed severe fibrinous pericarditis, moderate hydrocoelom, diffusely reddened lungs, and a green discoloration of the liver. Microscopic findings consisted in severe chronic fibrinous and necrosuppurative pericarditis, chronic pectoral rhabdomyonecrosis with fibrinoid necrosis and thrombosis of intralesional arteries, fibrinous visceral coelomitis, hepatic necrosis with severe hepatocellular cholestasis, and interstitial pneumonia with atelectasis. Salmonella sp. was cultured from the pericardial exudate. The case of salmonellosis reported herein is unusual because of the predominant component of chronic pericarditis.
