Local symptoms of infection?

summary

Wound infection is mainly caused by the invasion of bacteria into the human body. After our body is invaded by pathogens, we can mobilize the body's defense mechanism to kill the "invaders" and restore the stability of the body. Whether pathogens can cause infection after invading the body mainly depends on the virulence of pathogens and the body's resistance. Wound infection seriously affects the speed of wound healing. Let's share with you the local symptoms of infection?

Local symptoms of infection?

Different bacterial infection can produce different changes. Staphylococcus aureus infection is light yellow sticky secretion; Hemolytic streptococcus infection was light brown thin secretion; Pseudomonas aeruginosa infection was green or blue-green sticky secretion with sweet smell; Anaerobic bacteria infection can smell fecal odor.

There are dark gray or black necrotic spots on the wound surface, such as those infected by gram-negative bacilli. Bacterial invasion of deep blood vessels leads to ischemic necrosis, wound deepening and delayed wound healing. The early deliquescence and shedding of eschar or insect bite like changes indicate the occurrence of local infection.

The gray spots on the eschar or eschar wound mostly indicate fungal infection. The spots developed rapidly to the wound surface and fused into flaky villi. The surface color gradually became obvious, showing gray white, light green, light yellow or brown, and a thin layer of powder appeared on the wound after a few days.
