Cefoselis
Cefoselis, the fourth gen-eration of cephalosporin, is a β-lactam antibiotic. Cefoselis exhibits good activity against a wide range of Gram-positive and Gram-negative organisms. Cefoselis penetrates the blood-brain barrier.

In Vitro
Cefoselis, a new parenteral cephalosporin, was active against clinical isolates of both gram-positive and gram-negative aerobic bacteria. The activity of Cefoselis was similar to that of cefpirome and cefepime and generally superior to that of ceftazidime. Cefoselis showed potent antibacterial activity against Hemophilus influenzae and Moraxella catarrhalis.Cefoselis was highly active against MSSA and MSCNS. Cefoselis was poor in the activity against MRSA,MRCNS,PRSP and Enterococcus faecalis,and no activity for Enterococcus faecium.

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.
