Bacteremia is the presence of bacteria in the bloodstream that are alive and capable of reproducing. It is a type of bloodstream infection. [36] Bacteremia is defined as either a primary or secondary process. In primary bacteremia, bacteria have been directly introduced into the bloodstream. [37] Injection drug use may lead to primary bacteremia.
Colorized scanning electron micrograph of a human neutrophil ingesting MRSA. Methicillin-resistant Staphylococcus aureus (MRSA) is a group of gram-positive bacteria that are genetically distinct from other strains of Staphylococcus aureus. MRSA is responsible for several difficult-to-treat infections in humans.
Without antibiotic treatment, S. aureus bacteremia has a case fatality rate around 80%. [3] With antibiotic treatment, case fatality rates range from 15% to 50% depending on the age and health of the patient, as well as the antibiotic resistance of the S. aureus strain.
The Centers for Disease Control now recommends that initial antibiotic treatment regimens for infections with this bacterium be extended to 2–6 weeks. [2] Conventional antibiotic regimens used to treat H. cinaedi bacteremia in immune-incompetent individuals is reported to have a mortality rate after 30 days of treatment of 6.3%. [6]
Common symptoms of Staphylococcus aureus food poisoning include: a rapid onset which is usually 1–6 hours, nausea, explosive vomiting for up to 24 hours, abdominal cramps/pain, headache, weakness, diarrhea and usually a subnormal body temperature. Symptoms usually start one to six hours after eating and last less than 12 hours.
Walking pneumonia, a lung infection caused by the bacterium Mycoplasma pneumoniae, tends to be most common among older children and adolescents but in 2024 has been rampant among young children.
Other potential causes of similar signs and symptoms include anaphylaxis, adrenal insufficiency, low blood volume, heart failure, and pulmonary embolism. [2] Sepsis requires immediate treatment with intravenous fluids and antimicrobial medications. [1] [5] Ongoing care and stabilization often continues in an intensive care unit. [1]
The classic symptoms of a bacterial infection are localized redness, heat, swelling and pain. One of the hallmarks of a bacterial infection is local pain, pain that is in a specific part of the body. For example, if a cut occurs and is infected with bacteria, pain occurs at the site of the infection.
