Clinical manifestations include enteritis, lymphadenitis and pneumonia in foals. Foals with pneumonia are infected during the first days of life, although clinical symptoms manifest mainly between 1 and 6 months of age. Susceptibility to infection is related to: amount of microorganism inhaled or ingested; decline of humoral immunity; immune system immaturity and failure in cellular response. The objective of this study is to report the case of a Criollo foal with pneumonia by Rhodococcus equi, with the description of diagnosis and therapeutic methods.Case: In the Hospital of Veterinary Clinics of UFPel, it was attended a Criollo foal, 3 months old, with tachycardia, dyspnea, hyperthermia, mild bilateral nasal mucopurulent secretion and bilateral pulmonary rattling sounds. In CBC it was found hyperfi brinogenemia, leukocytosis with neutrophilia and normocytic normochromic anemia. In the thorax radiographic examination it was evidenced areas with increased radiopacity and irregular edges in dorsal and caudal lung fi eld. In the transtracheal fl uid it was isolated Rhodococcus equi bacteria and submitted to antibiogram test. Treatment was based on azithromycin (10 mg/kg), rifampicin (2.5 mg/kg) orally (PO) for 60 days, fl unixin meglumine
