Broad-spectrum antibiotic The term broad-spectrum antibiotic refers to an antibiotic that acts against a wide range of disease-causing bacteria. A broad-spectrum antibiotic acts against both Gram-positive and Gram-negative bacteria, in contrast to a narrow-spectrum antibiotic, which is effective against specific families of bacteria. An example of a commonly used broad-spectrum antibiotic is ampicillin.

Which Antibiotic is the Most Effective on Bacteria? A broad-spectrum antibiotic can be used to treat a wide range of infections. A narrow-spectrum antibiotic is only effective against a few types of bacteria. There are antibiotics that attack aerobic bacteria, while others work against anaerobic bacteria. Aerobic bacteria need oxygen, while anaerobic bacteria don't.n antibiotic is given for the treatment of an infection caused by bacteria. Antibiotics target microorganisms such as bacteria, fungi and parasites. However, they are not effective against viruses.

This assignment must be completed prior to attending this lab! Antibiotics effective against procaryotes which kill or inhibit a wide range of Gram-positive and Gram-negative bacteria are said to be broad spectrum . If effective mainly against Gram-positive or Gram-negative bacteria, they are narrow spectrum.

Penicillin Medical uses[edit] The term penicillin is often used generically to refer to benzylpenicillin (penicillin G, the original penicillin found in 1928), procaine benzylpenicillin (procaine penicillin), benzathine benzylpenicillin (benzathine penicillin), and phenoxymethylpenicillin (penicillin V).

- They are mainly bactericidal, are especially active against gram-positive organisms, and, with the exception of hypersensitivity reactions, show a particularly low toxic action on animal tissue. Penicillins are a certain collection of antibiotics that eliminate infection causing bacteria.Also known in short as pen or PCN, they originate from a type of fungi called Penicillium fungi. They are used in the treatment or prevention of many different bacterial infections, usually caused by Gram-positive organisms.enicillins are all β-Lactam (Beta-Lactam) antibiotics, which are antibiotic molecules with a β-Lactam nucleus. There are a number of penicillin types, that react to bacteria in a variety of degrees, some of these are: 1  ampicillin.

History of Antibiotics Antibiotics can also be classified based on their chemical structure. A similar level of effectiveness, toxicity and side-effects is rendered by the antibiotics of same structural group. Broad spectrum antibiotics are effective against a broad range of microorganisms in comparison to narrow spectrum antibiotics. Bactericidal antibiotics kill the bacteria whereas bacteriostatic antibiotics halt the growth of bacteria.

Hormonal IUDs In addition to birth control, hormonal IUD are used for prevention and treatment of: 1  heavy menstrual periods. 2  Endometriosis and chronic pelvic pain. 3  Adenomyosis and dysmenorrhea. 4  Anemia. In some cases, use of a hormonal IUD may prevent a need for a hysterectomy.

Narrow Spectrum Antibiotics Tigecycline may also be considered a tetracycline antibiotic, though it is usually classified as a glycylcycline antibiotic. Trimethoprim: Trimethoprim (INN) is a bacteriostatic antibiotic mainly used in the prophylaxis and treatment of urinary tract infections.

Penicillin and ampicillin Penicillin was discovered by Alexander Fleming in 1928 and was first used in clinical trials in 1942. Addition of an amino group to the benzylpenicillin molecule resulted in the creation of ampicillin, a drug with a broadened spectrum of activity. Penicillin and ampicillin exert their bactericidal effect by inhibiting microbial cell wall synthesis.

Lincoln County Sheriff Arrested More arrests, including of sheriff's office workers, are possible as the federal probe into Lincoln County continues, Hoverson said. A $20,000 bond was set Saturday in Oklahoma City federal court for the three deputies, and a Monday detention hearing was set for McLain, 45. The four remained in custody Saturday.

- Pharmacodynamics. Penicillin V is a penicillin beta-lactam antibiotic used in the treatment of bacterial infections caused by susceptible, usually gram-positive, organisms. The name penicillin can either refer to several variants of penicillin available, or to the group of antibiotics derived from the penicillins.hese are organic compounds containing the penicillin core structure, which is structurally characterized by a penam ring bearing two methyl groups at position 2, and an amide group at position 6 [starting from the sulfur atom at position 1].

Narrow Spectrum Antibiotics Uses Of Narrow Spectrum Antibiotics: Narrow spectrum antibiotics are used for the specific infection when the causative organism is known. Advantages Of Narrow Spectrum Antibiotics: 1  The narrow-spectrum antibiotic will not kill as many of the normal microorganisms in the body as the broad spectrum antibiotics. 2  The narrow spectrum antibiotic will cause less resistance of the bacteria as it will deal with only specific bacteria.

Classification of Penicillin Antibiotics Print Print. Penicillin is a group of antibiotics that are commonly used to treat different types of gram positive and gram negative bacterial infections. In their structure, beta lactam ring is located due to this reason these drugs are also called as beta lactam antibiotics.

Penicillin Penicillin antibiotics were among the first medications to be effective against many bacterial infections caused by staphylococci and streptococci. Penicillins are still widely used today, though many types of bacteria have developed resistance following extensive use. About 10% of people report that they are allergic to penicillin; however, up to 90% of this group may not actually be allergic. Serious allergies only occur in about 0.03%. All penicillins are β-lactam antibiotics. Penicillin was discovered in 1928 by Scottish scientist Alexander Fleming.

The History of Penicillin Penicillin is one of the earliest discovered and widely used antibiotic agents, derived from the Penicillium mold. Antibiotics are natural substances that are released by bacteria and fungi into the their environment, as a means of inhibiting other organisms-it is chemical warfare on a microscopic scale.

Food_and_Nutritional_Toxicology Since the introduction of penicillin, a variety of other classes of antibiotics have been discovered and put to use in fighting bacterial infections. Each class of antibiotics has its own mode of action or MOA. The mode of action is specifically how the drug works to disable or kill bacteria.

Penicillin-binding Proteins Penicillin and other beta-lactam antibiotics (named for an unusual, highly reactive lactam ring) are very efficient and have few side effects (apart from allergic reactions in some people). This is because the penicillin attacks a process that is unique to bacteria and not found in higher organisms.

- Antibiotics differ in the types of bacteria they work against. Antibiotics that affect a wide range of bacteria are called broad spectrum antibiotics (e.g. amoxycillin and gentamicin). Antibiotics that affect only a few types of bacteria are called narrow spectrum antibiotics (e.g. penicillin).ntibiotics are used for a range of other infections caused by bacteria, including urinary tract infections, skin infections and infected wounds.
