Narrow-spectrum antibiotics are medications that specifically target a limited range of bacteria, usually either Gram-positive or Gram-negative organisms, rather than a broad array of bacterial species. This targeted approach helps minimize the impact on the body's normal flora and reduces the risk of developing antibiotic resistance. They are often used when the specific type of infection-causing bacteria is known, allowing for precise treatment. Examples include penicillin, which primarily affects Gram-positive bacteria.

Differentiate between broad-spectrum and narrow-spectrum antibiotics?
A broad-spectrum antibiotic acts against many different kinds of disease-causing bacteria, including both gram-positive and gram-negative bacteria. A narrow-spectrum antibiotic acts only against specific families of bacteria.
Why are broad spectrum antibiotics used and what benefits do they provide in comparison to narrow spectrum antibiotics?
Broad spectrum antibiotics are used to treat a wide range of bacterial infections because they are effective against a variety of bacteria. This is in contrast to narrow spectrum antibiotics, which target specific types of bacteria. The benefit of broad spectrum antibiotics is that they can quickly and effectively treat infections when the specific bacteria causing the infection is unknown or when multiple types of bacteria are involved. This can help prevent the spread of infection and improve patient outcomes.
Why narrow spectrum is better than road spectrum?
Narrow-spectrum antibiotics target specific types of bacteria, reducing the risk of resistance development and minimizing harm to beneficial bacteria in the body. Broad-spectrum antibiotics, on the other hand, can kill a wide range of bacteria, including beneficial ones, leading to disruptions in the body's microbiota and potential for resistant strains to emerge. Moreover, narrow-spectrum antibiotics are more focused and efficient in treating infections caused by known bacteria types, whereas broad-spectrum antibiotics may be unnecessary and contribute to antibiotic resistance when not needed.
Antimicrobics effective against only gram positive bacteria would be termed?
narrow-spectrum drugs
What is broad or narrow spectrum?
Term broad and narrow spectrum are used in antibiotics The broad spectrum antibiotic can have its effect on many microbial species like penicillin and a narro spectrum antibiotic have its effect on one or few species
What is a very narrow range of wavelengths in the electromagnetic spectrum that humans can see?
The visible light spectrum is the narrow range of wavelengths in the electromagnetic spectrum that humans can see, typically between 400 to 700 nanometers. Beyond this range lie ultraviolet and infrared radiation, which are invisible to the human eye.
What is a narrow spectrum antibiotic effective against?
Narrow spectrum antibiotics are effective against just gram positive bacteria, just gram negative bacteria, or only a few specified species. Examples include: penicillin G, gentamicin, clindamycin, and gentamicin.
WHAT IS ultra-broad spectrum?
It is a term for antibiotics. An ultra broad range antibiotic can be used against many no. of microbes not a particular microbe. Meropenem is an ultra broad spectrum antibiotic.
Is Isoniazid considered narrow spectrum?
narrow or broad
Is a beetle a or narrow spectrum?
broad spectrum beetles, yes.
What are the classification schemes for antibiotics based on?
bacterial spectrum (broad versus narrow), route of administration (injectable versus oral versus topical), or type of activity (bactericidal versus bacteriostatic)
How do broad-spectrum antibiotics work?
The Broad Spectrum Antibiotics -are any of a variety of substances, usually obtained from microorganisms, that inhibit the growth of or destroy certain other microorganisms.The great number of diverse antibiotics currently available can be classified in different ways, e.g., by their chemical structure, their microbial origin, or their mode of action.They are also frequently designated by their effective range. Tetracycline is the most widely used broad-spectrum antibiotics, are effective against both Gram-positive and Gram-negative bacteria, as well as against rickettsia (any of a group of parasitic bacteria that live in the tissues of ticks, mites, and other arthropods, and cause disease when transmitted to man and other animals) and psittacosis-causing organisms. Ciprofloxacin (Cipro) is another broad spectrum antibiotic, effective in the treatment of mild infections of the urinary tract and sinuses. The medium-spectrum antibiotics bacitracin, the Erythromycin, penicillin, and the Cephalosporins (any of a group of broad-spectrum antibiotics obtained from fungi of the genus Cephalosporium) are effective primarily against Gram-positive bacteria, although the streptomycin group is effective against some Gram-negative and Gram-positive bacteria. Polymixin are narrow-spectrum antibiotics effective against only a few species of bacteria.
