whats the purpose of gram staining
used to differentiate bacteria into 2 major groups based on differences in their call wall structure
what colour do gram positive bacteria go and why
retain crystal violet stain due to having a thick peptidoglycan layer in their cell walls.
what colour do gram negative bacteria go and why
do not retain the purple stain and appear pink/red after taking up the counterstain. Thinner peptidoglycan layer and an outer membrane.
how is gram staining helpful
Classified bacteria quickly Choosing the right antibiotics Identifying bacterial species
why is accurate identification of disease essential
Correct diagnosis leads to correct treatment it aids in avoiding antibiotic resistance, good cost efficiency helps reduce harm to non targets Prevents the spread Effective quarantine measures Protects native ecosystems Legal and regulatory compliance Pubic health
