Lipid A modification-induced colistin-resistant < em > Klebsiella variicola < /em > from healthy adults
Conclusions. We found that colistin resistance in K. variicola was mediated by the modification of lipid A. Although the isolate was obtained from faecal samples of healthy adults, colistin-resistant K. variicola challenges public health as an opportunistic pathogen.PMID:37261959 | DOI:10.1099/jmm.0.001680 (Source: Journal of Medical Microbiology)

Unravelling the flexibility of < em > Mycobacterium tuberculosis: < /em > an escape way for the bacilli
J Med Microbiol. 2023 Jun;72(6). doi: 10.1099/jmm.0.001695.ABSTRACTThe persistence of Mycobacterium tuberculosis makes it difficult to eradicate the associated infection from the host. The flexible nature of mycobacteria and their ability to adapt to adverse host conditions give rise to different drug-tolerant phenotypes. Granuloma formation restricts nutrient supply, limits oxygen availability and exposes bacteria to a low pH environment, resulting in non-replicating bacteria. These non-replicating mycobacteria, which need high doses and long exposure to anti-tubercular drugs, are the root cause of lengthy chemotherapy. N...

Enhanced monitoring of healthcare shower water in augmented and non-augmented care wards showing persistence of < em > Pseudomonas aeruginosa < /em > despite remediation work
Conclusions. We demonstrate the difficulties in eradicating P. aeruginosa from hospital plumbing, particularly when contamination is no longer sporadic. Non-augmented care settings are reservoirs of P. aeruginosa and should not be overlooked in outbreak investigations. Antimicrobial-impregnated materials may be ineffective once colonization with P. aeruginosa is established beyond the hose and head. Reducing hose-length insufficient to prevent cross-contamination from shower drains. P. aeruginosa colonization can be transient in both drain and shower hose/head. Frequent microbiological monitoring suggests testing frequenci...

Expansion of hantavirus infection during the SARS-CoV-2 pandemic in Bosnia and Herzegovina, 2021
Conclusion. The reported infections were probably caused by exposure of individuals to at-risk areas inhabited by contaminated rodents as natural reservoirs of hantavirus. As a highly endemic area, B and H requires continuous monitoring and increased awareness of this problem.PMID:37255412 | DOI:10.1099/jmm.0.001687 (Source: Journal of Medical Microbiology)
