Aim: Characterization of morphologic changes in listeria cells under the effect of metabolites of human intestine microflora enterococci.

Materials And Methods: Culture of Listeria monocytogenes 88-BK cells was cultivated in the presence of enterococci waste products (experiment) or without them (control). The samples obtained were studied by atomic-force microscopy (AFM) in contact mode using scanning probe microscope SMM-2000.

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.

A 4-month course of spasmex (15 mg three times a day) was conducted in 57 females (age 18-69 years, mean age 48 years) suffering from imperative urination manifesting as pollakiuria, imperative urges and urgent urinary incontinence in combination with sexual disorders. After the treatment the score of urination disorders went down from 21.4 to 12.
