I think the yellow arrows show a guide were it goes or maybe tissue fluids!
Pseudomonas aeruginosa is of concern in burn patients beacuse it can cause infections like AIDS,diabetes mellitus , etc.
Pseudomonas aeruginosa is a common bacteria that can be found in soil, water, and other environmental niches. Burn wounds are intricate microenvironments where bacterial pathogens like P. aeruginosa can cause infections. Typical virulence factors like pyocyanin and pyoverdine expressed at higher levels than they would have under conventional laboratory conditions.
Elastase is secreted as well, is primarily responsible for the host tissues' degradation. P. aeruginosa infections cause severe consequences mostly in organisms with weakened natural defences. Examples of these circumstances include burn wound patients.
