Bacillus Calmette-Guérin (BCG) is an attenuated form of used for intravesical treatment of bladder carcinoma. Aortic infection has been rare. In the present report, we have described the case of a patient with an infrarenal mycotic aortic pseudoaneurysm and para-aortic abscess after intravesical bacillus Calmette-Guérin and cystectomy. Sampling of the abscess demonstrated acid-fast bacilli. Given the hostile anatomy of the abdomen, he was offered endovascular aortic repair. A thoracic endograft was used to cover the lesion. The patient was discharged on postoperative day 2 without incident. He was seen at 1 and 6 months with resolution of his pseudoaneurysm found on the imaging studies. The technique shows promise for stabilizing such lesions with close surveillance.

Polyphosphate kinases (PPK) play crucial roles in various biological processes, including energy storage and stress responses, through their interaction with inorganic polyphosphate (polyP) and the intracellular nucleotide pool. Members of the PPK family 2 (PPK2s) catalyse polyP‑consuming phosphorylation of nucleotides. In this study, we characterised two PPK2 enzymes from Bacillus cereus (BcPPK2) and Lysinibacillus fusiformis (LfPPK2) to investigate their substrate specificity and potential for selective nucleotide synthesis.

Biofilms formed by several bacterial strains still pose a significant challenge to healthcare due to their resistance to conventional treatment approaches, including antibiotics. This study explores the potential of loading natural extracts with antimicrobial activities into β-cyclodextrin (βCD) nanoparticles, which are FDA-approved and have superior biocompatibility owing to their cyclic sugar structures, for biofilm eradication. An inclusion complex of βCD carrying essential oils (BOS) was prepared and characterized with regard to its physicochemical properties, antimicrobial efficacy, and antibiofilm activities.

Purpose: Gut microbiota dysbiosis significantly impacts ulcerative colitis (UC) progression and exacerbation. Probiotics show promise in UC management. This study evaluated the effects of different doses of LV149, an aquatic-derived probiotic, on gut injury repair in male C57BL/6 mice with dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) and investigated the underlying mechanisms.

Marine mucilage disasters, primarily caused by global warming and marine pollution, threaten food security and the sustainability of marine food resources. This study assessed the microbial risks to public health in common sole, deep-water rose shrimp, European anchovy, Atlantic horse mackerel and Mediterranean mussel following the mucilage disaster in the Sea of Marmara in 2021. The total viable count, total Enterobacteriaceae count and the presence of Escherichia coli O157:H7, Salmonella spp.
