Rhodococcus equi is a Gram-positive, encapsulated, pleomorphic, intracellular bacillus, which mainly affects foals. Despite often being fatal it is still a neglected pathogen. The main objective of this study is to establish the etiological diagnosis in a clinical case of pneumonia in foals using basic bacteriology techniques. The strain referred to has been collected from a 32-day-old foal with the following symptoms: fever, dyspnea, abdominal breathing, cough and a deeply altered general condition. The isolation of the bacteria has been performed on Lowenstein- Jensen selective medium and the identification has been done based on morpho-cultural and biochemical features. Consequently, an antibiogram was performed and it showed that the isolated R. equi strain is sensitive to rifampicin and azithromycin thus the therapeutic protocol was corrected.
