The cerebrospinal fluid (CSF) Gram stain suggested Streptococcus pneumoniae : Gram-positive diplococci with a surrounding clear area indicative of a bacterial capsule. Her CSF and blood cultures grew penicillin-resistant S pneumoniae serotype 35B. This serotype is not included in the 13-valent ...
Good site,what is the relationship between endospores stain and gram nagetive and gram positive stain…? Reply Dagmawi February 17, 2016 at 1:09 PM Thanks a lot if sources are in hand please send the characteristics of gram negative and positive bacteria on media’s (colony characterization, ...
Some have a strong capsule made up of polysaccharides. Gram-positive bacteria shape Despite most bacteria being differentiated by the Gram staining dyes, the observation under the Microscope reveals more features that can be used to define and characterize these bacteria. ...

Apart from loose slime, some of the cells (both Gram negative and Gram positive bacteria) have been shown to form capsules (consisting of high molecular-weight viscous polysaccharides) on their surface. While the capsule is formed on the surface of the outer membrane in Gram negative bacteria,...

These bacteria are comprised of a thin polysaccharide capsule which can protect them from phagocytosis in addition to a slime layer which is composed of monosaccharides, proteins, and small peptides that are useful for cell attachment and biofilm formation. These bacteria represent common skin ...
10,11 One of these mechanisms is an outer capsule or biofilm that extends beyond the cell wall itself and interfaces with the external milieu.1,11 Hydrolase enzymes located within the cytoplasmic membrane, called β-lactamases, serve a protective role for the bacteria.1,11 Once attacked by the...
