Early-onset neonatal sepsis is found to be 0.77 to 1 per 100,000 live births in the U.S. In premature babies, the incidence and mortality rates are higher due to the weakness of their immune system. For infants with low birth weight, cases of early-onset sepsis is found to be about 26 per 1,000 and 8 per 1,000 live births.
Early onset sepsis can occur in the first week of life. It usually is apparent on the first day after birth. This type of infection is usually acquired before the birth of the infant. Premature rupture of membranes and other obstetrical complications can add to the risk of early-onset sepsis. If the amniotic membrane has been ruptured greater ...
Bacteremia can have several important health consequences. Immune responses to the bacteria can cause sepsis and septic shock, which, particularly if severe sepsis and then septic shock occurs, have high mortality rates, especially if not treated quickly (though, if treated early, currently mild sepsis can usually be dealt with successfully).

GBS it is also an important pathogen in a diversity of fish species, leading to serious economic losses in many species of fish worldwide. GBS causes severe epidemics in farmed fish, causing sepsis and external and internal hemorrhages. GBS infection has been reported from wild and captive fish and has been involved in epizootics in many countries.
The pathophysiology of septic shock is not entirely understood, but it is known that a key role in the development of severe sepsis is played by an immune and coagulation response to an infection. Both pro-inflammatory and anti-inflammatory responses play a role in septic shock. [ 8 ]
Purpura fulminans is a presenting feature of severe acute sepsis, such as Neisseria meningitidis, Streptococcus pneumoniae, Group A and B Streptococci, and less commonly with Haemophilus influenzae, Staphylococcus aureus, Capnocytophaga canimorsus [8] or Plasmodium falciparum (malaria) infections, particularly in individuals with asplenia.

Neonatal meningitis is a serious medical condition in infants that is rapidly fatal if untreated.Meningitis, an inflammation of the meninges, the protective membranes of the central nervous system, is more common in the neonatal period (infants less than 44 days old) than any other time in life, and is an important cause of morbidity and mortality globally.
The origins of pathophysiology as a distinct field date back to the late 18th century. The first known lectures on the subject were delivered by Professor August Friedrich Hecker at the University of Erfurt in 1790, and in 1791, he published the first textbook on pathophysiology, Grundriss der Physiologia pathologica [2], spanning 770 pages.
