Indicated for complicated skin/skin structure infections, soft tissue infections and complicated intra-abdominal infections. Effective for gram-positive, gram-negative, anaerobic, and against multi-antibiotic resistant bacteria (such as Staphylococcus aureus [MRSA] and Acinetobacter baumannii), but not effective for Pseudomonas spp. and Proteus ...
A colored electron microscopy image of methicillin-resistant staphylococcus aureus (), a bacterium commonly targeted by broad-spectrum antibioticsA 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]
Detailedly, broad-spectrum antibiotics can kill or inhibit a wide range of microorganisms; extended-spectrum antibiotic can kill or inhibit Gram positive bacteria and some Gram negative bacteria; narrow-spectrum antibiotic can only kill or inhibit limited species of bacteria. [1] [2] [3]
Based upon a number of observations including that the gram-positive bacteria are the major producers of antibiotics and that, in general, gram-negative bacteria are resistant to them, it has been proposed that the outer cell membrane in gram-negative bacteria (diderms) has evolved as a protective mechanism against antibiotic selection pressure.
Staphylococcus aureus is a gram-positive spherically shaped bacterium, a member of the Bacillota, and is a usual member of the microbiota of the body, frequently found in the upper respiratory tract and on the skin. It is often positive for catalase and nitrate reduction and is a facultative anaerobe, meaning that it can grow without oxygen. [1]
One of the main components is neomycin sulfate, which is a type of antibiotic discovered in 1949 by microbiologist Selman Waksman at Rutgers University. [21] Neomycin belongs to the aminoglycoside class of antibiotics and fights against Gram positive and gram negative bacteria. The antibiotic is often used to prevent risk of bacterial ...
The spectrum of activity of the carbapenems against gram-positive bacteria is fairly broad, but not as exceptionally so as in the case of gram-negative bacteria. Good activity is seen against methicillin-sensitive strains of Staphylococcus species, but many other antibiotics provide coverage for such infections.
Linezolid is an antibiotic used for the treatment of infections caused by Gram-positive bacteria that are resistant to other antibiotics. [9] [10] Linezolid is active against most Gram-positive bacteria that cause disease, including streptococci, vancomycin-resistant enterococci (VRE), and methicillin-resistant Staphylococcus aureus (MRSA).
