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 caused more than 100,000 deaths worldwide attributable to antimicrobial resistance in 2019.
Staphylococcus aureus is the most common cause of healthcare-associated bacteremia in North and South America and is also an important cause of community-acquired bacteremia. [14] Skin ulceration or wounds, respiratory tract infections, and IV drug use are the most important causes of community-acquired staph aureus bacteremia.
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.
S. aureus is also implicated [6] in toxic shock syndrome; during the 1980s some tampons allowed the rapid growth of S. aureus, which released toxins that were absorbed into the bloodstream. Any S. aureus infection can cause the staphylococcal scalded skin syndrome , a cutaneous reaction to exotoxin absorbed into the bloodstream.
A Cochrane review found that while it is an effective treatment for shigellosis it also produces more significant adverse effects than other antibiotic drugs. [43] Staphylococcus aureus infections: No: No: No: In vitro and in vivo activity against both non-resistant and methicillin-resistant Staphylococcus aureus (MRSA) infections. [44] [45 ...
Vancomycin is a glycopeptide antibiotic medication used to treat certain bacterial infections. [7] It is administered intravenously (injection into a vein) to treat complicated skin infections, bloodstream infections, endocarditis, bone and joint infections, and meningitis caused by methicillin-resistant Staphylococcus aureus. [8]
The evolution of bacteria on a "Mega-Plate" petri dish A list of antibiotic resistant bacteria is provided below. These bacteria have shown antibiotic resistance (or antimicrobial resistance). Gram positive Clostridioides difficile Clostridioides difficile is a nosocomial pathogen that causes diarrheal disease worldwide. Diarrhea caused by C. difficile can be life-threatening. Infections are ...
As many hospital-acquired infections caused by bacteria such as methicillin-resistant Staphylococcus aureus, methicillin-susceptible Staphylococcus aureus, and Clostridioides difficile are caused by a breach of these protocols, it is common that affected patients make medical negligence claims against the hospital in question.
