Multi‐Targeting Carnosic Acid Kills Drug‐Resistant Helicobacter pylori With Narrow‐Spectrum Activity

Advanced Science, Volume 13, Issue 50, 7 September 2026.
Carnosic acid selectively eradicates drug‐resistant Helicobacter pylori through a multi‐targeted mechanism involving urease inhibition, membrane disruption, and biofilm eradication. It exhibits no detectable resistance, potent in vivo efficacy, and minimal impact on gut microbiota, positioning it as a promising narrow‐spectrum lead compound against ...

Characterization of antimicrobial resistance among Proteus mirabilis isolates from catheter-associated urinary tract infections and non-catheter-associated urinary tract infections in Egypt

BMC Infectious Diseases
Background Recent worldwide reports of increased numbers of multidrug-resistant (MDR) Proteus mirabilis (P. mirabilis) isolates, particularly those producing extended-spectrum β-lactamases (ESBLs), are alarming. P.

Phosphatase of Proteus mirabilis

, 2020
Cell-free preparations of Proteus mirabilis contained a phosphatase (EC 3.1.3.1), whose activity surpassed that of alkaline phosphatase from Escherichia coli. Phosphatase was also found in the culture liquid of P. mirabilis.

Aging and periodontitis increase brain dissemination of oral bacteria

Journal of Periodontology, Volume 97, Issue 9, Page 1965-1979, September 2026.
Abstract Background The microbiome is a dynamic system that changes throughout life. Studies have revealed the relationship between periodontal disease and the oral microbiota; however, the impact of periodontal disease on the expression of senescence markers and on the inflammaging of the oral and systemic microbiome remains unclear.

Cryptic Lysogeny in Proteus mirabilis

Journal of General Virology, 1973
Summary Proteus mirabilis strains 13 and 5006 on rare occasions liberate temperate phages, 13M and 5006M, which may reinfect parent strains. These prophages are not inducible but the probability of phage liberation may be increased by growth in nitrosoguanidine. P. mirabilis strain 34 liberates a phage, φ34, spontaneously. Strain 34 is doubly lysogenic

Silk Investment in Gifts By Males of the Nuptial Feeding Spider Pisaura Mirabilis (Araneae: Pisauridae). [PDF]

, 1996
Adult males of the hunting spider Pisaura mirabilis wrap up prey with silk and pass these nuptial gifts to females prior to copulation. The females digest the nuptial gifts, including the silk, during mating.

Detecting Antibiotic Resistance in Strains of Selected Gram‐Negative Bacterial Species Using Raman Spectroscopy

Journal of Raman Spectroscopy, Volume 57, Issue 9, Page 1554-1564, September 2026.
Raman spectroscopy successfully identified antibiotic‐resistant Gram‐negative strains. Resistant strains of four bacterial species were discriminated from sensitive ones with 99.1% accuracy using PLS regression. The method allows for rapid, label‐free detection of antibiotic resistance.

Adult Blow Flies Host Diverse Carrion‐Associated Microbiomes

New Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
Blow flies (Diptera: Calliphoridae) perform important yet often overlooked roles in ecosystems as decomposers, pollinators and vectors of disease. Central to these functions are their associations with microbial communities, which are maintained through close contact with diverse microbe‐rich substrates such as carrion, dung and flowers.
