Sepsis is caused by many organisms including bacteria, viruses, and fungi. [10] Common locations for the primary infection include the lungs, brain, urinary tract, skin, and abdominal organs. [2] Risk factors include being very young or old, a weakened immune system from conditions such as cancer or diabetes, major trauma, and burns. [1]
E. faecalis is found in most healthy individuals, but can cause endocarditis and sepsis, urinary tract infections (UTIs), meningitis, and other infections in humans. [7] [8] Several virulence factors are thought to contribute to E. faecalis infections.
This is a shortened version of the first chapter of the ICD-9: Infectious and Parasitic Diseases. It covers ICD codes 001 to 139. The full chapter can be found on pages 49 to 99 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
Streptococcus bovis is a group of strains of Gram-positive bacteria, originally described as a species, [5] [6] that in humans is associated with urinary tract infections, endocarditis, sepsis, [7] and colorectal cancer. [8] S. bovis is commonly found in the alimentary tract of cattle, sheep, and other ruminants, [9] and may cause ruminal acidosis.
Aerococcus urinae is a member of the bacterial genus Aerococcus.The bacterium is a Gram-positive, catalase-negative coccus growing in clusters. Isolates of this genus were originally isolated in 1953 from samples collected in the air and dust of occupied rooms and were distinguished by their tetrad cellular arrangements. [2]
Enterobacter cloacae is a member of the normal gut flora of many humans and is not usually a primary pathogen. [9] Some strains have been associated with urinary tract and respiratory tract infections in immunocompromised individuals.
Candida parapsilosis is a fungal species of yeast that has become a significant cause of sepsis and of wound and tissue infections in immunocompromised people. Unlike Candida albicans and Candida tropicalis, C. parapsilosis is not an obligate human pathogen, having been isolated from nonhuman sources such as domestic animals, insects and soil. [1]
Pyuria is the condition of urine containing white blood cells or pus.Defined as the presence of 6-10 or more neutrophils per high power field of unspun, voided mid-stream urine, it can be a sign of a bacterial urinary tract infection.
