Streptococcus pyogenes is a species of Gram-positive bacteria. These bacteria are aerotolerant and an extracellular bacterium, made up of non-motile and non-sporing cocci. As expected with a streptococci, it is clinically important in human illness. It is an infrequent, but usually pathogenic, part of the skin microbiota.

S. aureus (/ˌstæfɪləˈkɒkəs ˈɔːriəs, -loʊ-/,^[12][13] Greek σταφυλόκοκκος, "grape-cluster berry", Latin aureus, "golden") is a facultative anaerobic, gram-positive coccal (round) bacterium also known as "golden staph" and "oro staphira". S. aureusis non-motile and does not form spores.

P. aeruginosa is a facultative anaerobe, as it is well adapted to proliferate in conditions of partial or total oxygen depletion.

Atypical: Legionella, Chlamydia, Mycoplasma (Macrolides)

Bacteria is usually easy to kill because they can easily be invaded with meds that flood them whereas virus is harder to kill bc of their lack of cells (non-living organisms).
