is a rapidly growing mycobacterium found in water and soil that can cause local cutaneous infections in immunocompetent hosts but more frequently affects immunocompromised patients. Typically, patients will present with painful subcutaneous nodules of the joints or soft tissues from traumatic inoculation. However, exhibiting a sporotrichoid-like pattern of these nodules is uncommon. Herein, we report a case of sporotrichoid-like distribution of cutaneous in a patient with systemic lupus erythematosus on significant immunosuppressive medications. Clinicians treating immunocompromised patients should be cognizant of their propensity to develop unusual infections and atypical presentations.

Background: Mycobacterium avium complex (MAC) is a common pathogen causing non-tuberculous mycobacterial infections, primarily affecting the lungs. Disseminated MAC disease occurs mainly in immunocompromised individuals, such as those with acquired immunodeficiency syndrome, hematological malignancies, or those positive for anti-interferon-γ antibodies. However, its occurrence in solid organ transplant recipients is uncommon.

Background: In the UK, booster COVID-19 vaccinations have been recommended biannually to people considered immune vulnerable. We investigated, at a population level, whether the absence of detectable anti-SARS-CoV-2 spike protein IgG antibody (anti-S Ab) following three or more vaccinations in immunosuppressed individuals was associated with greater risks of infection and severity of infection.
Methods: In this prospective cohort study using UK national disease registers, we recruited participants with solid organ transplants (SOTs), rare autoimmune rheumatic diseases (RAIRDs), and lymphoid malignancies.

Patients receiving kidney transplant experience immunosuppression, which increases the risk of bacterial, viral, fungal, and parasitic infections. Q fever is a potentially fatal infectious disease that affects immunocompromised renal transplant recipients and has implications in terms of severe consequences for the donor's kidney. A patient with acute Q fever infection following kidney transplantation was admitted to the Tsinghua Changgung Hospital in Beijing, China, in March 2021.

is a widely distributed nosocomial pathogen that causes various acute and chronic infections, particularly in immunocompromised patients. In this study, the activities of the K9-specific virulent phage AM24 and phage-encoded depolymerase DepAPK09 were assessed using in vivo mouse sepsis and burn skin infection models. In the mouse sepsis model, in the case of prevention or early treatment, a single K9-specific phage or recombinant depolymerase injection was able to protect 100% of the mice after parenteral infection with a lethal dose of of the K9-type, with complete eradication of the pathogen.
