All those diagnoses have been converted to sepsis, again with modifiers, in ICD-10, such as "Sepsis due to streptococcus".The current terms are dependent on the microorganism that is present: bacteremia if bacteria are present in the blood at abnormal levels and are the causative issue, viremia for viruses, and fungemia for a fungus.By the end of the 19th century, it was widely believed that microbes produced substances that could injure the mammalian host and that soluble toxins released during infection caused the fever and shock that were commonplace during severe infections. Pfeiffer coined the term endotoxin at the beginning of the 20th century to denote the pyrogenic principle associated with Vibrio cholerae. It was soon realized that endotoxins were expressed by most and perhaps all gram-negative bacteria. The lipopolysaccharide character of enteric endotoxins was elucidated in 1944 by Shear. The molecular character of this material was determined by Luderitz et al. in 1973.It was discovered in 1965 that a strain of C3H/HeJ mouse was immune to the endotoxin-induced shock. The genetic locus for this effect was dubbed Lps. These mice were also found to be hyper susceptible to infection by gram-negative bacteria. These observations were finally linked in 1998 by the discovery of the toll-like receptor gene 4 (TLR 4). Genetic mapping work, performed over a period of five years, showed that TLR4 was the sole candidate locus within the Lps critical region; this strongly implied that a mutation within TLR4 must account for the lipopolysaccharide resistance phenotype.
Elective right hemicolectomy may be used to prevent recurrence but is generally not recommended"...The authors have found nonoperative treatment highly effective in patients who do not manifest signs of peritonitis, perforation, gastrointestinal hemorrhage, or clinical deterioration. Recurrent typhlitis was frequent after conservative therapy (recurrence rate, 67 percent), however," as based on studies from the 1980s

Prognosis
Inflammation can spread to other parts of the gut in patients with typhlitis. The condition can also cause the cecum to become distended and can cut off its blood supply. This and other factors can result in necrosis and perforation of the bowel, which can cause peritonitis and sepsis.Historically, the mortality rate for typhlitis was as high as 50%, mostly because it is frequently associated with bowel perforation. More recent studies have demonstrated better outcomes with prompt medical management, generally with resolution of symptoms with neutrophil recovery without death
