Mycobacterium colombiense (M. colombiense) is a member of the Mycobacterium avium complex (MAC). To our knowledge, this is the third case report of an M. colombiense infection. An 80-year-old man, immunocompromised by myelodysplastic syndrome (MDS), developed a skin rash with exfoliation and eruption on his face and scalp. Mycobacteria were detected in pus samples. Broad-range polymerase chain reaction (PCR) revealed the mycobacteria to be M. colombiense. The lesions resolved after daily administration of rifampicin, ethambutol, and clarithromycin. In conclusion, broad-range PCR identified this rare mycobacterium, allowing for the administration of appropriate combination antibiotic therapy.

We present an AIDS patient coinfected with nontuberculous mycobacteria, and COVID-19, who finally recovered from the coinfection. The 36-year-old man had two hospitalizations. In the first hospitalization, the patient was diagnosed with , HIV, and COVID-19 quickly and accurately, and the corresponding treatment worked well.

an infrequently reported non-tuberculous mycobacterium, is characterized by its slow-growing nature and capacity to simulate malignancies in clinical presentation. This report details a case of disseminated infection initially misidentified as cancer due to atypical symptoms, negative etiological tests, and imaging suggestive of a neoplastic disease However, comprehensive diagnostic investigations, including a bone marrow biopsy and flow cytometry analysis, excluded malignancy as the diagnosis. The patient subsequently developed palpable masses, from which a definitive diagnosis was made using metagenomic Next-Generation Sequencing (mNGS) and culture of aspirate.

Background: pneumonia in HIV-infected patients is relatively unusual but is associated with a high mortality rate, as well as high rates of misdiagnosis and delayed diagnosis. Clinical metagenome next-generation sequencing (mNGS) may have potential for its accurate and timely diagnosis.
Case Presentation: We retrospectively reviewed the medical records of three HIV-infected patients who presented with pneumonia in Zhejiang Province between January 2019 and December 2020.

Background: Pneumoconiosis patients have a high prevalence of pulmonary infections, which can complicate diagnosis and treatment. And there is no comprehensive study of the microbiome of patients with pneumoconiosis. The application of metagenomic next-generation sequencing (mNGS) fills the gap to some extent by analyzing the lung microbiota of pneumoconiosis population while achieving accurate diagnosis.
