Tigecycline is used to treat different kinds of bacterial infections, including complicated skin and structure infections, complicated intra-abdominal infections and community-acquired bacterial pneumonia. [citation needed] Tigecycline is a glycylcycline antibiotic that covers MRSA and Gram-negative organisms:
Acute cystitis in women: This antibiotic is not recommended for children and 75 and up of age: Inactivates enolpyruvyl transferase, thereby blocking cell wall synthesis Fusidic acid: Fucidin: Metronidazole: Flagyl: Infections caused by anaerobic bacteria; also amoebiasis, trichomoniasis, giardiasis
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. MRSA is any strain of S. aureus that has developed (through natural selection) or acquired (through horizontal gene transfer) a multiple drug resistance to beta-lactam antibiotics.
Narrow-spectrum antibiotics have low propensity to induce bacterial resistance and are less likely to disrupt the microbiome (normal microflora). [3] On the other hand, indiscriminate use of broad-spectrum antibiotics may not only induce the development of bacterial resistance and promote the emergency of multidrug-resistant organisms, but also cause off-target effects due to dysbiosis.
Nafcillin sodium is a narrow-spectrum [1] beta-lactam antibiotic [2] of the penicillin class. As a beta-lactamase-resistant penicillin, it is used to treat infections caused by Gram-positive bacteria, in particular, species of staphylococci that are resistant to other penicillins.
It is used to treat urinary tract infections, methicillin-resistant Staphylococcus aureus (MRSA) skin infections, travelers' diarrhea, respiratory tract infections, and cholera, among others. [ 2 ] [ 7 ] It is used both to treat and prevent pneumocystis pneumonia and toxoplasmosis in people with HIV/AIDS and other causes of immunosuppression. [ 2 ]
The benefits of this long-lasting nature are less frequent dosing requirements while maintaining efficacy. [5] Dalbavancin is an antibiotic used to treat acute bacterial skin and skin structure infections (ABSSSI) in adults caused by susceptible Gram-positive organisms, including methicillin-resistant Staphylococcus aureus (MRSA).
