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.
It can cause peritonitis, [6] endophthalmitis, [7] sepsis and bacteremia. Similar symptoms although also very rare can be seen by infections of P. luteola. [8] P. plecoglossicida is a fish pathogenic species, causing hemorrhagic ascites in the ayu (Plecoglossus altivelis). [9] P. anguilliseptica is also a fish pathogen. [10]
Methicillin-resistant Staphylococcus aureus (MRSA, often pronounced / ˈ m ɜːr s ə / or / ɛ m ɑːr ɛ s eɪ /), is one of a number of greatly feared strains of S. aureus which have become resistant to most β-lactam antibiotics. For this reason, vancomycin, a glycopeptide antibiotic, is commonly used to combat MRSA. Vancomycin inhibits the ...
P. mirabilis is generally susceptible to most antibiotics apart from tetracycline and nitrofurantoin, [4] but 10–20% of P. mirabilis strains are also resistant to first-generation cephalosporins and ampicillin. [5] Proteus mirabilis in trypticase soy agar growth media
A plasmid-encoded hemolysin, called the cytolysin, is important for pathogenesis in animal models of infection, and the cytolysin in combination with high-level gentamicin resistance is associated with a five-fold increase in risk of death in human bacteremia patients. [9] [10] [11] A plasmid-encoded adhesin [12] called "aggregation substance ...
The diagnosis of vancomycin-resistant Staphylococcus aureus (VRSA) is performed by performing susceptibility testing on a single S. aureus isolate to vancomycin. This is accomplished by first assessing the isolate's minimum inhibitory concentration (MIC) using standard laboratory methods, including disc diffusion, gradient strip diffusion, and automated antimicrobial susceptibility testing ...
