Skin and Skin Structure Peptococcus Infection
Peptococcus species are gram-positive, obligate anaerobic cocci that form part of the normal human flora, particularly in the gastrointestinal and genitourinary tracts. Although generally considered…
Skin and Skin Structure Morganella morganii Infection
Morganella morganii is a facultative anaerobic, gram-negative bacillus belonging to the Enterobacteriaceae family. Though traditionally considered an opportunistic pathogen, it has emerged as a significant…
Skin and Skin Structure Klebsiella Infection
Klebsiella species, primarily Klebsiella pneumoniae, are gram-negative bacilli associated with healthcare-associated infections and opportunistic community-acquired cases. While most commonly implicated in urinary tract and respiratory…
Skin and Skin Structure Infections
Skin and skin structure infections (SSSIs) encompass a wide spectrum of bacterial infections involving the epidermis, dermis, subcutaneous tissue, fascia, and muscle. These infections vary…
Skin and Skin Structure Fusobacterium Infections
Fusobacterium species are obligate anaerobic, gram-negative bacilli commonly found in the oropharynx, gastrointestinal tract, and genitourinary system. Though often commensal, these bacteria can cause severe…
Skin and Skin Structure Enterococcus Infections
Enterococcus species, primarily Enterococcus faecalis and Enterococcus faecium, are gram-positive, facultative anaerobic cocci that commonly inhabit the gastrointestinal tract. Although often considered low-virulence organisms, they…
Skin and Skin Structure Enterobacter Infections
Enterobacter species, primarily Enterobacter cloacae and Enterobacter aerogenes (now Klebsiella aerogenes), are gram-negative, facultative anaerobic bacilli within the Enterobacteriaceae family. While commonly colonizing the gastrointestinal…
Skin and Skin Structure Escherichia coli Infections
Escherichia coli (E. coli) is a facultative anaerobic, gram-negative bacillus that predominantly inhabits the gastrointestinal tract. While widely recognized as a cause of urinary tract…
Skin and Skin Structure Clostridium Infections
Clostridium species are anaerobic, spore-forming, gram-positive bacilli found ubiquitously in soil, the gastrointestinal tract, and human skin. Certain species, particularly Clostridium perfringens, Clostridium septicum, and…
Skin and Skin Structure Citrobacter Infections
Citrobacter species, members of the Enterobacteriaceae family, are gram-negative, facultatively anaerobic bacilli. While commonly associated with urinary tract and gastrointestinal infections, they are increasingly implicated…
