We report a case of pulmonary nocardiosis in a 41-year-old asthma patient. Chest radiographs showed bilateral air space and consolidations.Acid-fast branching filaments were demonstrated in sputum, and the grown organism was identified phenotypically and confirmed using16S rDNA sequencing (accession no. KX500116). The patient received a combination of medical treatments, but developed complicat...

Idiopathic CD4 T-lymphocytopenia (ICL) is a rare immunodeficiency characterized by low CD4 T-lymphocyte count, which usually manifests with opportunistic infections. Nocardia as an opportunistic pathogen infecting patients with this condition has rarely been reported. Here, we describe the case of a 46-year-old male who presented with lung mass and respiratory and systemic symptoms and was even...

Nocardia is an uncommon Gram-positive organism. It typically appears as delicate filamentous Gram-positive branching rods. In the United States it was estimated to be approximately 500 to 1000 new cases per year. The organism causes disease in immunocompromised individuals with pulmonary infection representing the most common site of infection. Nocardia mikamii has been a recently isolated path...

Background. Nocardiosis is a rare disease that mainly affects severely immunocompromised patients. Symptoms are nonspecific and microbiological isolation is difficult, hiding the diagnosis. Treatment should be guided by species and susceptibility testing. Findings. We report a clinical case of a disseminated nocardiosis in a patient with HIV and HVB infections. Interpretation. Diagnosis should ...

Localized and multisystem nocardiosis is an opportunistic disease that occurs commonly in immunocompromised patients. Rarely, it is also seen in immunocompetent individuals. The most common disease sites include lung, skin and central nervous system. We report a case of 73 years old man who is a known case of rheumatoid arthritis for more than 15 years and was on Methotrexate and Prednisolone. ...

© 2017 Advanced Biomedical Research | Published by Wolters Kluwer Medknow Sir, Shirani et al. recently reported an article entitled, “Nocardial brain abscess in a patient with pulmonary alveolar proteinosis” (DOI: 10.4103/2277-9175.164004).[1] The genus Nocardia is a Gram-positive aerobic, partially acid-fast, and fi lamentous bacterium that causes nocardial infections (nocardiosis) in human. T...

The patient was a 71-year-old man. Two months after using prednisolone at a dose of 80 mg/day for the treatment of drug-induced interstitial pneumonia induced by chemotherapy following lung cancer surgery, his chest x-ray fi lm showed cavitary shadows, and Nocardia farcinica was detected from subcutaneous abscess, sputum, urine, and blood cultures. Thus, disseminated nocardiosis involving multi...
