Article Synopsis
- The study used atomic force microscopy to examine how low doses of ampicillin affect the size and structure of Escherichia coli and Bacillus cereus bacteria.
- The results showed that both types of bacteria increased in size due to inner osmotic pressure affecting their weakened cell walls.
- E. coli displayed unusual elongated shapes and structural anomalies, while B. cereus primarily changed from a rod to a spherical shape, releasing peptidoglycan fragments as a result of the antibiotic.
The alkylhydroxybenzene (AHB) autoregulatory factors d1 (fd1) of microorganisms have been found to directly interact with highly polymeric DNA. This circumstance results in changes, related to alterations in the topology of this macromolecule, in DNA physicochemical properties. The physicochemical properties of DNA in the presence of chemical analogues of microbial AHBs (methylresorcinol; hexylresorcinol; and 2-(4-hydroxyphenyl)ethane-1-ol, also known as tyrosol) were investigated using adsorption spectrophotometry, fluorometry, heat denaturation, viscosimetry, and electrophoresis in agarose gel.
