Gram-positive bacteria organisms

Actinomycete Nontaxonomic term applied to a group of high G -1- C base composition. Gram-positive bacteria that have a superficial resemblance to fungi. Includes many but not all organisms belonging to the order Actinomycetales. 

In addition, all organisms studied contained an amino sugar or hexosamine. Generally, the walls of Gram-positive bacteria are richer in hexosamine than the Gram-negative forms. 

First-generation cephalosporins, introduced into human medicine in the 1960 s and 1970 s, are basically similar in antibacterial activity and differ mainly in their pharmacokinetic properties. These include all of the currently available orally active cephalosporins, and are relatively susceptible to beta-lactamase, active against most Gram-positive bacteria and have a limited spectrum of activity against the Gram-negative organisms.
