Which of the following is a true statement about antibiotic resistant bacte

they attack the immune system

they can spread through the air

they are not affected by antibiotics

they only attack human, not animals

They are not affected by antibiotics.

Explanation:

Antibiotics resistant bacteria are bacteria that are resistant or not affected by antibiotics rather they develop adaptations to antibiotics by living and surviving in the presence of antibiotics.

They resist to antibiotics by changing in a way that reduces the effectiveness of antibiotics. Examples include penicillin resistant enterococcus, methicillin resistant staphylococcus aureus e.t.c.

they are not affected by antibiotics

Explanation:

Resistance Bacteria prevent antibiotics from affecting them. They build immune against the activity of the antibiotics in there system by preventing its function.

This can be done by pushing the antibiotic out of the system reducing its concentration. They also change membrane system and preventing permeability of the antibiotic in the membrane. Some bacterial also destroy the active ingredient in the antibiotics thereby preventing the activities.

Hence antibiotic resistance bacteria are not affected by the antibiotic by inhibiting there activities.
