A case of spontaneous synergistic bacterial gangrene occurring after external pelvic irradiation is presented in a 25-year-old woman with invasive cervical cancer. Treatment consisted of aggressive antibiotic therapy and extensive excision and debridement followed by split-thickness skin grafting. Both recovery and cosmetic results were satisfactory. The pathophysiology, predisposing factors, and treatment modalities are presented.

An alkaline pH in soils reduces Fe availability, limiting Fe uptake, compromising plant growth, and showing chlorosis due to a decrease in chlorophyll content. To achieve proper Fe homeostasis, dicotyledonous plants activate a battery of strategies involving not only Fe absorption mechanisms, but also releasing phyto-siderophores and recruiting siderophore-producing bacterial strains. A screening for siderophore-producing bacterial isolates from the rhizosphere of was carried out, resulting in two strains, Z8.

Green propolis, particularly from the unique flora of the Brazilian Caatinga biome, has gained significant interest due to its diverse chemical composition and biological activities. This study focuses on the chemical characterization and antimicrobial evaluation of Caatinga green propolis. Twelve compounds were isolated through different chromatographic techniques, including flavanones (naringenin, 7--methyleriodictyol, sakuranetin), flavones (hispidulin, cirsimaritin), flavonols (quercetin, quercetin-3-methyl ether, kaempferol, 6-methoxykaempferol, viscosine, penduletin), and one chalcone (kukulkanin B).

Salmonid rickettsial septicemia (SRS) is a critical sanitary problem in the Chilean aquaculture industry since it induces the highest mortality rate in salmonids among all infectious diseases. , a facultative intracellular bacterium, is the biological agent of SRS. In Chile, two genogroups of , designated as LF-89 and EM-90, have been identified.

Biofilm formation by is a major cause of secondary food contamination, leading to significant economic losses. While rhamnolipids (RLs) have shown effectiveness against , their ability to remove biofilms is limited when used alone. Ultrasound (US) is a non-thermal sterilization technique that has been found to enhance the delivery of antimicrobial agents, but it is not highly effective on its own.

This study aimed to explore the interactions among genetic determinants influencing ciprofloxacin resistance in . Treatment with PAβN, an efflux pump inhibitor, resulted in a 4-32-fold reduction in the minimum inhibitory concentration (MIC) across all 18 ciprofloxacin-resistant isolates. Notably, isolates without point mutations reverted from resistance to sensitivity.
