Mycobacterium simiae is a non-tuberculosis mycobacterium that does commonly cause clinical disease in immunocompromised patients with or without AIDS. We describe a case of M. simiae pulmonary infection in a patient without immunodeficiency syndrome, who had a history of Mycobacterium tuberculosis infections.

Soil microbial life-history strategies, as indicated by rRNA operon (rrn) copy numbers, strongly influence agro-ecosystem functioning. Long-term N fertilization causes strong and lasting changes in soil properties, yet its impact on microbial strategies remains largely unexplored. Using long-term field experiments across three agro-ecosystems, we consistently found that N fertilization strongly decreased soil C: N ratio and pH, further increasing the community-level rrn copy number, including both average rrn copy number and total 16S rRNA copy number.

Article Synopsis
- Atypical or nontuberculous mycobacteria (NTM) are environmental organisms linked to opportunistic infections, particularly in immunocompromised patients, with rapid-growing NTM commonly associated with hospital-acquired infections.
- This retrospective study analyzed 13 cases of injection abscess caused by NTM in children over six years, noting that these patients were otherwise healthy, with no chronic illnesses, and all had received standard vaccinations.
- The findings highlight the importance of suspecting NTM infections in patients not responding to treatment, emphasizing the need for strict aseptic techniques to prevent contamination in healthcare settings.

, a slow-growing non-tuberculous mycobacterium (NTM), presents diagnostic challenges due to its resemblance to and other NTMs. While NTM infections and tuberculosis share clinical and radiological features, their management strategies differ. Accurate differentiation is pivotal, as misdiagnosing NTM infections such as MDR-TB can lead to ineffective treatments.

Article Synopsis
- Non-tuberculous mycobacterial pulmonary disease (NTM-PD) is an increasing health issue, mainly caused by slow-growing mycobacteria (SGM) in Europe.
- A study analyzed 135 CT scans from 84 patients to investigate the correlation between clinical data and radiological features of various SGM species, especially emphasizing Mycobacterium avium complex.
- Findings suggest that patients with M. intracellulare had more severe CT results, and the study indicates that a specific CT scoring system could be beneficial for tracking disease progression and treatment decisions.
