The structure of the carbohydrate backbone of the lipid A-core region of the LPS from Shewanella algae strain BrY was analysed. The LPS was N,O-deacylated to give three products, which were isolated and studied by chemical methods, NMR and mass spectrometry: [Carbohydrate structures: see text]. All monosaccharides except L-rhamnose had the D-configuration. This LPS presents a second example (after S. oneidensis) of the structure with a novel linking unit between the core and lipid A moieties, 8-amino-3,8-dideoxy-D-manno-oct-2-ulosonic acid (8-amino-Kdo).

This study aimed to determine the chemical composition of five essential oils (LEOs) using the gas chromatography-mass spectroscopy technique and to assess their antibacterial activity against four marine species, including , , , and . Sensitivity tests were performed using the disk diffusion and serial dilution methods. The results showed that all five LEOs exhibited antibacterial activity against the four tested marine species.

Marine microbial communities colonizing the skin of invertebrates constitute the primary barrier between host and environment, potentially exerting beneficial, neutral, or detrimental effects on host fitness. To evaluate the potential contribution of epibiotic bacteria to the survival of early developmental stages of Octopus mimus, bacterial isolates were obtained from eggs, paralarvae, and adults. Their enzymatic activities were determined, and antibacterial properties were assessed against common marine pathogens.

Article Synopsis
- - This study investigates genetic mechanisms behind the rising resistance of Shewanella algae to carbapenem antibiotics, focusing on the evolutionary changes that occur in response to treatment.
- - Researchers used advanced sequencing techniques to monitor a specific mutation (G547W) linked to increased expression of a protein that aids in resistance, demonstrating how bacterial populations can shift rapidly in response to antibiotic exposure.
- - The findings highlight how some resistant cells can exist even without antibiotics and suggest that these hidden populations contribute to resistance development during treatment, revealing complex interactions that influence medical outcomes.

Article Synopsis
- - The study examines the health and demographic characteristics of migrants who arrived in the Canary Islands via small boats from 2020 to 2022, highlighting significant health issues due to their journey.
- - Of the 193 patients, many suffered from acute patera syndrome (APS) and skin and soft tissue or musculoskeletal patera syndrome (SSTMSPS), with dehydration being the most common issue; most patients were young males from West Africa.
- - Findings indicate that timely identification of patera syndrome can lead to better treatment outcomes, emphasizing the importance of understanding the specific health challenges faced by these migrants.
