antibiotic 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.

Drugs with narrow therapeutic index as indicators in the risk management of hospitalised patients Abstract. 1  Drugs with narrow therapeutic index (NTI-drugs) are drugs with small differences between therapeutic and toxic doses. The pattern of drug-related problems (DRPs) associated with these drugs has not been explored. To investigate how, and to what extent drugs, with a narrow therapeutic index (NTI-drugs), as compared with other drugs, relate to different types of drug-related problems (DRPs) in hospitalised patients.

Narrow Spectrum Antibiotics Disadvantages Of Narrow Spectrum Antibiotics: 1  Narrow spectrum antibiotics can be used only if the causative organism is identified. 2  If you don’t choose the drug very carefully, the drug may not actually kill the microorganism causing the infection.

Extended-spectrum beta-lactamases (ESBLs): guidance, data, analysis The diagnosis, management and surveillance of extended-spectrum beta-lactamases (ESBLs). Bacteria that produce enzymes called extended-spectrum beta-lactamases (ESBLs) are resistant to many penicillin and cephalosporin antibiotics and often to other types of antibiotic. The 2 main bacteria that produce ESBLs are Escherichia coli (E. coli) and Klebsiella species.

- 3. Follow the 3 day rule: Broad spectrum antibiotics markedly alter the normal host flora about 3 days into therapy AND cultures should be back in 3 days so always reassess your antibiotic choices and narrow it when possible. 4. Assume nothing.

Dicloxacillin Dicloxacillin is a narrow-spectrum β-lactam antibiotic of the penicillin class. It is used to treat infections caused by susceptible Gram-positive bacteria. It is active against beta-lactamase-producing organisms such as Staphylococcus aureus, which would otherwise be resistant to most penicillins. Dicloxacillin is available under a variety of trade names including Diclocil.

Clavamox Clavamox is a broad spectrum antibiotic, a combination of amoxicillin and clavulanic Acid, used for infections caused by bacteria. Clavamox requires a prescription from your veterinarian, and is sold by the tablet.It is also available as oral drops.roven to generally be a safe anti-bacterial treatment. How it works: Clavamox combines the broad-spectrum antibiotic activity of amoxicillin with the unique beta-lactamase inhibiting effect of clavulanic acid which makes this product effective against beta-lactamase and non-beta-lactamase producing organisms.

Extended-Spectrum Beta-Lactamase- (ESBL)-Producing Bacteria Extended-spectrum beta-lactamases are enzymes made by certain kinds of germs (bacteria). These germs (or ESBL for short) break down several types of antibiotic medicine. So when you get sick because of ESBL, the infection is harder to treat and you may need different antibiotics. Infections caused by ESBL usually affect the urinary tract and gut (intestine). They can also infect wounds and the blood.

Oral Treatment Options for Ambulatory Patients with Urinary Tract Infections Caused by Extended-Spectrum-Î²-Lactamase-Producing Escherichia coli â¿ Escherichia coli is the most common pathogen of bacterial infections worldwide. As many as 80% of urinary tract infections (UTIs) are caused by E. coli. In 1980, resistance to extended-spectrum cephalosporins was found for the first time in Enterobacteriaceae showing no chromosomally encoded AmpC overexpression.

Extended Spectrum Beta Lactamase Extended Spectrum Beta-Lactamase (ESBL) is an enzyme made by some bacteria. The enzyme prevents certain antibiotics from being able to kill the bacteria. The bacteria then become resistant to the antibiotics. This means stronger antibiotics must be used to kill the bacteria. ESBL infections usually occur in the urinary tract, lungs, skin, blood, or abdomen.

- 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.
