1) Disinfectants. Non-selectively kill microbes on non-living surfaces. Bleach
2) Antiseptics. Selectively kill bacteria on living surfaces. Chlorhexadine
3) Antibiotics/Antifungals/Antiprotozoals . Selectively kill bacteria/fungi/protozoa inside the body
Antibiotics are either?

Bacteriocidal is…
They kill bacteria when present

What is Antimicrobial resistance?
is the ability of a microbe to resist the effects of medication that once could successfully treat the microbe
What is Antibiotic resistance?
is a subset of AMR, as it applies only to bacteria becoming resistant to antibiotics
What can the veterinary industry do about Antibiotic resistance?
Aseptic techniques and decrease nosocomial infections
Employ more modern and careful use of ABs. Do we really need 10 days of ABs?
Choose ABs based on the bacteria not the ROA
Perform more C&S
Check to see if owner’s can actually give the ABs successfully
Check to see that the full course has been given
Rethink food animal ABs
What shape are Cocci bacteria?
Round ball
What shape are Bacilli bacteria?
Rod
What shape are Spirochete bacteria?
Spiral
What shape are Filamentous bacteria?
Filaments/hair like
