Gram-negative bacteremia occurs more frequently in elderly populations (65 years or older) and is associated with higher morbidity and mortality in this population. [23] E.coli is the most common cause of community-acquired bacteremia accounting for approximately 75% of cases. [24] E.coli bacteremia is usually the result of a urinary tract ...
Streptococcus agalactiae is the most common human pathogen belonging to group B of the Lancefield classification of streptococci—hence the name of group B stretococcal (GBS). Infection with GBS can cause serious illness and sometimes death, especially in newborns, the elderly, and people with compromised immune systems.
It is the second-leading cause of death in non-coronary intensive care unit (ICU) and the tenth-most-common cause of death overall (the first being heart disease). [111] Children under 12 months of age and elderly people have the highest incidence of severe sepsis. [30]
Though pneumonia is the most common cause of bacterial sepsis in the elderly, the statistic that one out of three cases leads to sepsis is misleading, because it refers to the period before the ...
Streptococcus pneumoniae is the most common bacterial cause of pneumonia in all age groups except newborn infants. Streptococcus pneumoniae is a Gram-positive bacterium that often lives in the throat of people who do not have pneumonia. Other important Gram-positive causes of pneumonia are Staphylococcus aureus and Bacillus anthracis.
GBS is the leading cause of bacterial neonatal infection in the baby during gestation and after delivery with significant mortality rates in premature infants. GBS infections in the mother can cause chorioamnionitis (a severe infection of the placental tissues) infrequently, postpartum infections (after birth) and it had been related with ...
They are the most common cause of hospital-acquired infections accounting for approximately 40%. [117] Rates of asymptomatic bacteria in the urine increase with age from two to seven percent in women of child-bearing age to as high as 50% in elderly women in care homes. [ 42 ]
S. agalactiae, or group B streptococcus, GBS, causes pneumonia and meningitis in newborns and the elderly, with occasional systemic bacteremia. Importantly, Streptococcus agalactiae is the most common cause of meningitis in infants from one month to three months old.
