Comparison of the clinical, microbiological, radiological and haematological features of foals with pneumonia caused by Rhodococcus equi and other bacteria.

摘要: The purpose of this study was to compare the clinical, microbiological, radiological, haematological and cytological features foals with pneumonia caused by Rhodococcus equi infection other bacteria, in order provide markers for early diagnosis treatment. A retrospective 113 cases bacterial undertaken. Although there considerable overlap affected populations, R. were significantly younger had higher respiratory rates. Radiological evidence thoracic abscessation a sensitivity 71% specificity 85% pneumonia. Foals positive also peripheral white cell counts fibrinogen concentrations than animals not infected pathogen. Respiratory rate, concentration log neutrophil count retained final multivariate analysis. Using microbiological culture as 'gold standard', identification Gram-positive coccobacilli tracheal aspirates highly specific (91%), but poorly sensitive (35%) infection. White >20,000cells/μL (86% specificity), >700mg/dL (92% radiological (85% presence (91% specificity) pneumonic are suggestive justify targeted antimicrobial intervention while awaiting results.
