Pyrroxamycin
Pyrroxamycin is a novel antibiotic produced by Streptomyces, whose chemical structure was determined by chemical properties and X-ray crystallography and 13C NMR spectroscopy analysis. It is active against Gram-positive bacteria and dermatophytes. In this paper, the authors discuss the taxonomy, fermentation, isolation, physicochemical properties, chemical structure, and biological activity of the strain producing Pyrroxamycin.

Gram Staining of Tissue Sections
Gram staining of tissue sections is a histochemical technique used to differentiate Gram-positive and Gram-negative bacteria within histological specimens based on differences in bacterial cell wall structure and dye retention, adapted from classical bacteriological Gram staining into tissue-compatible “histological Gram stain” variants. In tissue applications, modifications of the Brown-Hopps and Brown-Brenn methods are commonly used to improve differentiation of microorganisms embedded within host connective tissue and to reduce overstaining or loss of Gram-negative signal, which are known limitations of earlier approaches. The principle relies on crystal violet-iodine complex retention in Gram-positive organisms and subsequent decolorization and counterstaining steps that allow contrast visualization of Gram-negative organisms against tissue background.
