PMLS MICROBIAL CONDITIONS PHASES OF THE BIOFILM FORMATION

Question 1

Enumerate the phases of the formation of the biofilm?

Answer 1

reversible attachment phase, irreversible attachment phase, Production of extracellular polymeric substance by the bacterial cells, biofilm maturation phase, and dispersal/detachment phase

Question 2

Adhesion to surface

Answer 2

reversible attachment phase

Question 3

In this case, irreversible attachment has already occurred; it will be very difficult

Answer 3

Production of Extracellular Polymeric Substances (EPS) by the bacterial cells

Question 4

Where the bacterial cells depart
from the biofilms and come back to independent planktonic lifestyle or unicellular lifestyle

Answer 4

Dispersal/Detachment Phase (Release)

Question 5

Bacterial cells synthesize and release signaling molecules to sense the presence of each other, conducing to the formation of microcolony and maturation of biofilms

Answer 5

biofilm maturation phase

Question 6

growth happens in this phase

Answer 6

biofilm maturation phase

Question 7

a phase where it is reversible

Answer 7

Reversible Attachment Phase

Question 8

what causes the phase to be irreversible?

Answer 8

production of Extracellular polymeric substances (EPS)

Question 9

EPS stands for?

Answer 9

Extracellular Polymeric Substances (EPS

Question 10

Bacteria attaches to any work
surface or equipment

Answer 10

Reversible Attachment Phase

Question 11

what is the indication that the phase is about to be in the phase of EPS?

Answer 11

presence of bacterial adhesins or fimbriae lipopolysaccharaide

Question 12

This is where other organisms attach to the bacterial colony, and they harmoniously multiply

Answer 12

biofilm maturation phase

Question 13

release of plankton

Answer 13

Dispersal/Detachment Phase (Release)

Question 14

at what phase is where personnels or ssusceptible groups are exposed to these planktonic bacteria

Answer 14

dispersal/detachment phase

Question 15

communication between bacteria

Answer 15

quorom sensince

Question 16

Bacterial cells synthesize and release signaling molecules to sense the presence of each other, conducing to the formation of microcolony and maturation of biofilms

Answer 16

biofilm maturation phase

Question 17

what is detrimental in healthcare?

Answer 17

biofilm formation

Question 18

different bacteria found in the biofilm are able to communicate between one another, sharing genetic material that provides resistance to certain antimicrobial substances or even medication

Answer 18

maturation phase

Question 19

single-celled organisms that adopt a multicellular
behavior

Answer 19

bacteria
