Pyogenic Liver Abscess Due to Rhodococcus equi in an Immunocompetent Host

Abstract: A case of pyogenic liver abscess (PLA) due to Rhodococcus equi in an immunocompetent individual was successfully treated by combining surgery and antibiotics. The R. equi-targeted antimicrobial agents erythromycin and rifampin were used only after surgical resection of the lesion and identification of the infective organism. CASE REPORTA 46-year-old man residing in the suburbs of the city of Rio de Janeiro, Brazil, was admitted to the university hospital with fever (39 to 40°C), right upper quadrant pain, naus… Show more

“…It is also recognized as an opportunistic pathogen of humans, particularly in human immunodeficiency virus (HIV)-infected immunocompromised persons [1,2]. The traditional identification of R. equi in clinical laboratories is usually performed by the characterization of colony and microscopic morphology, and biochemical tests using a commercial kit such as the API Coryne [3][4][5]. However, the battery of traditional tests is not always sufficient for the accurate identification of R. equi because of its potential variation of colony and microscopic morphology or biochemical inactivity [3,4].…”

“…14 However, little information is available in Brazil about virulence plasmid profiles of R. equi isolates from humans. [15][16][17] Intermediately virulent strains of R. equi are predominantly identified in HIV-positive patients, 2 the lymph nodes of pigs with and without lymphadenitis, 7,12 and, more recently, in lymph nodes of wild boars ( Sus scrofa ) in Hungary 10 and Brazil. 15 Furthermore, virulent R. equi strains also have been described in HIV-negative human patients.…”

“…Extrapulmonal R. equi infection can be primary and secondary, and usually is a late manifestation of initial lung infection as was the case in our patient. It is a multisistemic or local disease, usually presented as sepsis, fever of unknown origin, cerebral abscess, meningitis, pericarditis, osteomyelitis, subcutaneous abscess, regional lymphadenitis, mastoiditis, or wound infection 18,25,27,[31][32][33][34][35][36] . Because of the delayed diagnosis and treatment, frequent bacteriemias and dissemination of R. equi infection, almost all of these manifestations were seen in our patient.…”
