Tigecycline is a glycylcycline antibiotic that covers MRSA and Gram-negative organisms: Tigecycline can treat complicated skin and structure infections caused by; Escherichia coli, vancomycin-susceptible Enterococcus faecalis, methicillin-resistant Staphylococcus aureus (MRSA), Streptococcus agalactiae, Streptococcus anginosus grp ...
Clindamycin. Clindamycin is a lincosamide antibiotic medication used for the treatment of a number of bacterial infections, including osteomyelitis (bone) or joint infections, pelvic inflammatory disease, strep throat, pneumonia, acute otitis media (middle ear infections), and endocarditis. [ 5 ]
A broad- spectrum antibiotic is an antibiotic that acts on the two major bacterial groups, Gram-positive and Gram-negative, [1] or any antibiotic that acts against a wide range of disease-causing bacteria. [2] These medications are used when a bacterial infection is suspected but the group of bacteria is unknown (also called empiric therapy) or ...
Gram-positive: Some members of this group (in particular, those available in an oral formulation, and those with antipseudomonal activity) have decreased activity against gram-positive organisms. Activity against staphylococci and streptococci is less with the third-generation compounds than with the first- and second-generation compounds.
Gentamicin is a type of aminoglycoside [4] and works by disrupting the ability of the bacteria to make proteins, which typically kills the bacteria. [4] Gentamicin is naturally produced by the bacterium Micromonospora purpurea, [8][4] was patented in 1962, approved for medical use in 1964. [9]
Levofloxacin is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria. Like all quinolones, it functions by inhibiting the DNA gyrase and topoisomerase IV , two bacterial type IIA topoisomerases . [ 55 ]
Cefalexin. Cefalexin, also spelled cephalexin, is an antibiotic that can treat a number of bacterial infections. [4] It kills gram-positive and some gram-negative bacteria by disrupting the growth of the bacterial cell wall. [4] Cefalexin is a β-lactam antibiotic within the class of first-generation cephalosporins. [4]
Lincomycin is a narrow spectrum antibiotic with activity against Gram-positive and cell wall-less bacteria including pathogenic species of Streptococcus, Staphylococcus, and Mycoplasma. [7] Lincomycin is used to treat severe bacterial infections in patients who cannot use penicillin antibiotics.
