Endobronchial Enigma: A Clinically Rare Presentation of Nocardia beijingensis in an Immunocompetent Patient

Case Reports in Pulmonology, 2015
Nocardiosis is an opportunistic infection caused by the Gram-positive weakly acid-fast, filamentous aerobic Actinomycetes. The lungs are the primary site of infection mainly affecting immunocompromised patients. In rare circumstances even immunocompetent

NCY‐1 β‐Lactamase Activity Correlates With Antimicrobial Susceptibility of a Clinical Strain of Nocardia cyriacigeorgica

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
This study shows a strong correlation between the β‐lactam susceptibility profile of a clinical isolate of Nocardia cyriacigeorgica and the activity of its β‐lactamase, NCY‐1. Inhibitors of NCY‐1 reduce the minimum inhibitory concentration of amoxicillin.

Rapid Serological Detection of Anti‐GM‐CSF Autoantibodies in Autoimmune Pulmonary Alveolar Proteinosis Using a Novel Immunochromatographic Test

Respirology, Volume 31, Issue 2, Page 184-192, February 2026.
We developed a novel ICT with high clinical performance that can distinguish APAP patients from those with other pulmonary diseases. The rapid and simple detection of GMAbs in serum provided a new practical method for the diagnosis of APAP. See related editorial ABSTRACT Background and Objectives Anti‐GM‐CSF autoantibodies (GMAbs) are essential ...

Pulmonary nocardiosis revisited: A case series

Lung India, 2015
Pulmonary nocardiosis is a rising bacterial infection, with a high propensity for misdiagnosis. On account of a paucity of prospective studies, there is limited understanding on various aspects of its diagnosis and treatment.

The Incidence of Nocardiosis at Pulmonary and Extra – Pulmonary Sites [PDF]

Journal of Clinical and Diagnostic Research, 2013
Nocardiosis is a rare but well-established opportunistic infection. We are presenting two cases of Nocardiosis diagnosed in the microbiology laboratory, one in an immuno-competent elderly patient and the other in a immunocompromised patient with AIDS.

Case Report of a Solitary Brain Abscess due to Nocardia veterana in a Host Without Known Immunodeficiency

Case Reports in Infectious Diseases, Volume 2026, Issue 1, 2026.
Nocardiosis is a rare bacterial infection caused by a wide array of species of the genus Nocardia. These microbes are found ubiquitously in soil and cause infection mainly when immunocompromised hosts inhale these bacteria or from direct inoculation through breaks in the skin. Once infection is established, Nocardia spp.

Pulmonary Nocardia paucivorans Infection Mimicking Lung Cancer in an Immunocompetent Patient: A Case Report

Case Reports in Infectious Diseases, Volume 2026, Issue 1, 2026.
Background Pulmonary nocardiosis is uncommon and usually affects immunocompromised hosts, but it can occur in immunocompetent patients and mimic primary lung malignancy clinically and radiographically. Case Presentation A 52‐year‐old immunocompetent woman presented with one month of cough, hemoptysis, and mild shortness of breath after repeated hiking ...

Concurrent Nocardia, Cryptococcus and Mycobacterium Infections Unmask Anti–GM‐CSF Antibody–Associated Immunodeficiency and Pulmonary Alveolar Proteinosis: A Case Report

Case Reports in Infectious Diseases, Volume 2026, Issue 1, 2026.
Anti‐granulocyte macrophage colony stimulating factor (anti‐GM‐CSF) antibodies, classically associated with pulmonary alveolar proteinosis (PAP), are increasingly recognised as a cause of adult‐onset immunodeficiency predisposing to opportunistic infections. Coinfections with multiple opportunistic pathogens in this context are uncommon.

An Unusual Case of Cutaneous Nocardia cyriacigeorgica Infection Assuming the Appearance of Shingles

Case Reports in Infectious Diseases, Volume 2026, Issue 1, 2026.
Nocardia is an opportunistic organism that commonly infects the lungs of the immunocompromised and can cause disseminated infections. Diagnosis of Nocardia cyriacigeorgica is through culture and susceptibilities, aided by 16S rRNA sequencing. We report a case of a shingles‐like rash eruption due to Nocardia cyriacigeorgica in a 69‐year‐old patient with
