Can Streptococcus grow on nutrient agar?
Nutrient agar provides these resources for many types of microbes, from fungi like yeast and mold to common bacteria such as Streptococcus and Staphylococcus. The microbes that can be grown on complex media such as nutrient agar can be described as nonfastidious organisms.
Does ceftriaxone cover Streptococcus?
Ceftriaxone was extremely active against nonenterococcal streptococci (MIC90 0.07 microgram/ml or less) and quite active against methicillin-susceptible Staphylococcus aureus (MIC90 5 micrograms/ml or less).

Does Bactrim cover Streptococcus?
The sulfonamides should not be used for treatment of group A β-hemolytic streptococcal infections. In an established infection, they will not eradicate the streptococcus and, therefore, will not prevent sequelae such as rheumatic fever.
