Final answer:
Common pathogens of skin, wounds, and tissue abscesses include Gram-positive bacteria like Staphylococcus spp. and Streptococcus spp., opportunistic bacteria such as Pseudomonas aeruginosa, and various fungi, particularly in moist environments or those with compromised immune systems.
Step-by-step explanation:
The predominant pathogens that infect the skin, wounds, and tissue abscesses are primarily bacteria, including Gram-positive Staphylococcus spp. such as S. epidermidis and the more virulent S. aureus, as well as Streptococcus spp. These bacteria often breach the skin barrier through cuts or wounds.
Another significant pathogen is Pseudomonas aeruginosa, a Gram-negative bacterium that causes opportunistic infections, particularly in immunocompromised individuals or those with chronic liver disease. Fungal infections of the skin can occur in moist environments or through direct inoculation in wounds, especially in patients with weakened immune systems. To protect against such infections, skin integrity and proper wound care are essential.
