The cell wall protects bacteria from the external environment and keeps the contents of the cell together. Without a cell wall bacteria are not able to survive. Bacteria that are susceptible to Keflex antibiotic include Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, E. coli and several others.
