Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of bacteria is hardest to kill with antibiotics?
A
Gram positive
B
Gram negative
C
Gram neutral
D
None of the above
Explanation: 

Detailed explanation-1: -Their peptidoglycan layer is much thinner than that of gram-positive bacilli . Gram-negative bacteria are harder to kill because of their harder cell wall.

Detailed explanation-2: -Gram-negative bacteria are resistant to multiple drugs and are increasingly resistant to most available antibiotics.

Detailed explanation-3: -It is easier to kill gram-positive bacteria as compared to gram-negative bacteria. This is because gram-positive bacteria lack a hard protective outer layer. The peptidoglycan layer that surrounds gram-positive bacteria is capable of absorbing antibiotics and cleaning products, which are fatal to them.

Detailed explanation-4: -Gentamicin remains the drug of choice, but tobramycin may be preferred for Pseudomonas aeruginosa. Amikacin has the widest antibacterial spectrum of the aminoglycosides but is best reserved for infection caused by gentamicin-resistant organisms.

Detailed explanation-5: -Methicillin-Resistant Staphylococcus Aureus This type of bacteria is resistant to many antibiotics, including methicillin. Most methicillin-resistant Staphylococcus aureus, or MRSA, infections contracted outside of a hospital are skin infections.
