Nocardia is a Gram-positive, partially acid-fast, catalase-positive, and urease-positive bacterium that grows aerobically. We present an extremely rare case of cauda equina syndrome due to isolated intramedullary Nocardia farcinica infection. A 44-year-old male presented with low backache and gradually progressive weakness in bilateral lower limbs followed by paraplegia. He was found to have a well-defined, sharply demarcated ring-enhancing lesion located from T11-T12 to L3 vertebral body. He underwent laminectomy and decompression. The histopathological examination revealed a Gram-positive filamentous organism that looks like Nocardia. The culture report was suggestive of Nocardia farcinica. He was then treated with antibiotics and had a remarkable clinical and radiological improvement.

Background: Polymicrobial pulmonary infections, common in immunocompromised patients, often manifest more severe symptoms than monomicrobial infections. Clinical diagnosis delays may lead to mortality, emphasizing the importance of fast and accurate diagnosis for these patients. Metagenomic next-generation sequencing (mNGS), as an unbiased method capable of detecting all microbes, is a valuable tool to identify pathogens, particularly in cases where infections are difficult to diagnosis using conventional methods.

Background: Disseminated nocardiosis is a rare and potentially fatal disease, with a higher incidence in immunocompromised patients, such as those living with human immunodeficiency virus (HIV) or hematological malignancies, including lymphoma. Information on Nocardia spp. infection in Venezuela is limited.

Protein nanopores are emerging as versatile single-molecule sensors with broad applications in DNA and protein sequencing. However, their narrow size restricts the range of detectable analytes, necessitating the development of advanced nanopores to broaden their applications in biotechnology. This review highlights a natural hetero-oligomeric porin, Nocardia farcinica porin AB (NfpAB), based on the Gram-positive mycolata, Nocardia farcinica.

Rationale: Nocardia infections, although rare, pose significant challenges in diagnosis and treatment, especially when involving the central nervous system (CNS). Mortality rates in such cases can be high, highlighting the need for early recognition and tailored antimicrobial therapy.
Patient Concerns: A 58-year-old male with a history of chronic obstructive pulmonary disease, antineutrophil cytoplasmic antibody-associated glomerulonephritis, and steroid-induced diabetes mellitus presented with disorganized speech, fever, cough, dyspnea, and psychiatric symptoms.

Background: Nocardiosis is an opportunistic infection that has a low prevalence rate, its clinical manifestations are atypical and can be easily misdiagnosed as other diseases. The correct diagnosis and treatment are frequently delayed by various factors. In this case report, we present a pediatric patient with Neuromyelitis Optica Spectrum Disorders who developed Nocardia farcinica pneumonia complicated by pneumocystis jiroveci infection.
