Antimicrobial Activity Spectrum
There are two categories of bacteria that antibiotics can affect: narrow spectrum
and broad spectrum. Gram positive or gram negative bacteria are the only ones
that narrow spectrum antibiotics can kill. For instance, sodium fusidate only
kills staphylococcal bacteria. Amoxicillin is one example of a broad range
antibiotic, which works against both Gram-positive and Gram-negative bacteria.
Unlike narrow spectrum antibiotics, which are effective against particular
bacterial families, broad spectrum antibiotics are effective against both Gram-
positive and Gram-negative bacteria. Ampicillin is a typical example of a broad-
spectrum antibiotic. The following medical circumstances warrant the use of
broad spectrum antibiotics: empirically (i.e., based on the practitioner's
experience), before the causative bacteria has been formally identified, and
when there is a wide range of potential illnesses and delaying treatment could
result in a potentially serious illness. For instance, in cases of meningitis, if
broad-spectrum medicines are not started, the patient may die within hours. In
cases of super infections, where several bacterial species are causing illness and
necessitate the use of either a broad-spectrum antibiotic or combination
antibiotic therapy, broad spectrum antibiotics are also used to treat drug-
resistant bacteria that do not respond to other, more narrow spectrum
antibiotics. Three new classes of antibacterial antibiotics have been introduced
into clinical usage after a 40-year break in the discovery of new antibacterial
chemical classes: cyclic lipopeptides (like daptomycin), glycylcyclines (like
tigecycline), and oxazolidinones (like linezolid).

positive and Gram-negative bacteria. Ampicillin is a typical example of a broad-
spectrum antibiotic. The following medical circumstances warrant the use of
broad spectrum antibiotics: empirically (i.e., based on the practitioner's
experience), before the causative bacteria has been formally identified, and
when there is a wide range of potential illnesses and delaying treatment could
result in a potentially serious illness. For instance, in cases of meningitis, if
broad-spectrum medicines are not started, the patient may die within hours. In
cases of super infections, where several bacterial species are causing illness and
necessitate the use of either a broad-spectrum antibiotic or combination
antibiotic therapy, broad spectrum antibiotics are also used to treat drug-
resistant bacteria that do not respond to other, more narrow spectrum
antibiotics. Three new classes of antibacterial antibiotics have been introduced
into clinical usage after a 40-year break in the discovery of new antibacterial
chemical classes: cyclic lipopeptides (like daptomycin), glycylcyclines (like
tigecycline), and oxazolidinones (like linezolid).
There are two categories of bacteria that antibiotics can affect: narrow spectrum
and broad spectrum. Gram positive or gram negative bacteria are the only ones
that narrow spectrum antibiotics can kill. For instance, sodium fusidate only
kills staphylococcal bacteria. Amoxicillin is one example of a broad range
antibiotic, which works against both Gram-positive and Gram-negative bacteria.

result in a potentially serious illness. For instance, in cases of meningitis, if
broad-spectrum medicines are not started, the patient may die within hours. In
cases of super infections, where several bacterial species are causing illness and
necessitate the use of either a broad-spectrum antibiotic or combination
antibiotic therapy, broad spectrum antibiotics are also used to treat drug-
resistant bacteria that do not respond to other, more narrow spectrum
antibiotics. Three new classes of antibacterial antibiotics have been introduced
into clinical usage after a 40-year break in the discovery of new antibacterial
chemical classes: cyclic lipopeptides (like daptomycin), glycylcyclines (like
tigecycline), and oxazolidinones (like linezolid).
There are two categories of bacteria that antibiotics can affect: narrow spectrum
and broad spectrum. Gram positive or gram negative bacteria are the only ones
that narrow spectrum antibiotics can kill. For instance, sodium fusidate only
kills staphylococcal bacteria. Amoxicillin is one example of a broad range
antibiotic, which works against both Gram-positive and Gram-negative bacteria.
Unlike narrow spectrum antibiotics, which are effective against particular
bacterial families, broad spectrum antibiotics are effective against both Gram-
positive and Gram-negative bacteria. Ampicillin is a typical example of a broad-
spectrum antibiotic. The following medical circumstances warrant the use of
broad spectrum antibiotics: empirically (i.e., based on the practitioner's
experience), before the causative bacteria has been formally identified, and

resistant bacteria that do not respond to other, more narrow spectrum
antibiotics. Three new classes of antibacterial antibiotics have been introduced
into clinical usage after a 40-year break in the discovery of new antibacterial
chemical classes: cyclic lipopeptides (like daptomycin), glycylcyclines (like
tigecycline), and oxazolidinones (like linezolid).
There are two categories of bacteria that antibiotics can affect: narrow spectrum
and broad spectrum. Gram positive or gram negative bacteria are the only ones
that narrow spectrum antibiotics can kill. For instance, sodium fusidate only
kills staphylococcal bacteria. Amoxicillin is one example of a broad range
antibiotic, which works against both Gram-positive and Gram-negative bacteria.
Unlike narrow spectrum antibiotics, which are effective against particular
bacterial families, broad spectrum antibiotics are effective against both Gram-
positive and Gram-negative bacteria. Ampicillin is a typical example of a broad-
spectrum antibiotic. The following medical circumstances warrant the use of
broad spectrum antibiotics: empirically (i.e., based on the practitioner's
experience), before the causative bacteria has been formally identified, and
when there is a wide range of potential illnesses and delaying treatment could
result in a potentially serious illness. For instance, in cases of meningitis, if
broad-spectrum medicines are not started, the patient may die within hours. In
cases of super infections, where several bacterial species are causing illness and
necessitate the use of either a broad-spectrum antibiotic or combination
antibiotic therapy, broad spectrum antibiotics are also used to treat drug-
resistant bacteria that do not respond to other, more narrow spectrum
antibiotics. Three new classes of antibacterial antibiotics have been introduced

There are two categories of bacteria that antibiotics can affect: narrow spectrum
and broad spectrum. Gram positive or gram negative bacteria are the only ones
that narrow spectrum antibiotics can kill. For instance, sodium fusidate only
kills staphylococcal bacteria. Amoxicillin is one example of a broad range
antibiotic, which works against both Gram-positive and Gram-negative bacteria.
Unlike narrow spectrum antibiotics, which are effective against particular
bacterial families, broad spectrum antibiotics are effective against both Gram-
positive and Gram-negative bacteria. Ampicillin is a typical example of a broad-
spectrum antibiotic. The following medical circumstances warrant the use of
broad spectrum antibiotics: empirically (i.e., based on the practitioner's
experience), before the causative bacteria has been formally identified, and
when there is a wide range of potential illnesses and delaying treatment could
result in a potentially serious illness. For instance, in cases of meningitis, if
broad-spectrum medicines are not started, the patient may die within hours. In
cases of super infections, where several bacterial species are causing illness and
necessitate the use of either a broad-spectrum antibiotic or combination
antibiotic therapy, broad spectrum antibiotics are also used to treat drug-
resistant bacteria that do not respond to other, more narrow spectrum
antibiotics. Three new classes of antibacterial antibiotics have been introduced
into clinical usage after a 40-year break in the discovery of new antibacterial
chemical classes: cyclic lipopeptides (like daptomycin), glycylcyclines (like
tigecycline), and oxazolidinones (like linezolid).

antibiotic, which works against both Gram-positive and Gram-negative bacteria.
Unlike narrow spectrum antibiotics, which are effective against particular
bacterial families, broad spectrum antibiotics are effective against both Gram-
positive and Gram-negative bacteria. Ampicillin is a typical example of a broad-
spectrum antibiotic. The following medical circumstances warrant the use of
broad spectrum antibiotics: empirically (i.e., based on the practitioner's
experience), before the causative bacteria has been formally identified, and
when there is a wide range of potential illnesses and delaying treatment could
result in a potentially serious illness. For instance, in cases of meningitis, if
broad-spectrum medicines are not started, the patient may die within hours. In
cases of super infections, where several bacterial species are causing illness and
necessitate the use of either a broad-spectrum antibiotic or combination
antibiotic therapy, broad spectrum antibiotics are also used to treat drug-
resistant bacteria that do not respond to other, more narrow spectrum
antibiotics. Three new classes of antibacterial antibiotics have been introduced
into clinical usage after a 40-year break in the discovery of new antibacterial
chemical classes: cyclic lipopeptides (like daptomycin), glycylcyclines (like
tigecycline), and oxazolidinones (like linezolid).

broad spectrum antibiotics: empirically (i.e., based on the practitioner's
experience), before the causative bacteria has been formally identified, and
when there is a wide range of potential illnesses and delaying treatment could
result in a potentially serious illness. For instance, in cases of meningitis, if
broad-spectrum medicines are not started, the patient may die within hours. In
cases of super infections, where several bacterial species are causing illness and
necessitate the use of either a broad-spectrum antibiotic or combination
antibiotic therapy, broad spectrum antibiotics are also used to treat drug-
resistant bacteria that do not respond to other, more narrow spectrum
antibiotics. Three new classes of antibacterial antibiotics have been introduced
into clinical usage after a 40-year break in the discovery of new antibacterial
chemical classes: cyclic lipopeptides (like daptomycin), glycylcyclines (like
tigecycline), and oxazolidinones (like linezolid).
There are two categories of bacteria that antibiotics can affect: narrow spectrum
and broad spectrum. Gram positive or gram negative bacteria are the only ones
that narrow spectrum antibiotics can kill. For instance, sodium fusidate only
kills staphylococcal bacteria. Amoxicillin is one example of a broad range
antibiotic, which works against both Gram-positive and Gram-negative bacteria.
Unlike narrow spectrum antibiotics, which are effective against particular
bacterial families, broad spectrum antibiotics are effective against both Gram-
positive and Gram-negative bacteria. Ampicillin is a typical example of a broad-

cases of super infections, where several bacterial species are causing illness and
necessitate the use of either a broad-spectrum antibiotic or combination
antibiotic therapy, broad spectrum antibiotics are also used to treat drug-
resistant bacteria that do not respond to other, more narrow spectrum
antibiotics. Three new classes of antibacterial antibiotics have been introduced
into clinical usage after a 40-year break in the discovery of new antibacterial
chemical classes: cyclic lipopeptides (like daptomycin), glycylcyclines (like
tigecycline), and oxazolidinones (like linezolid).
There are two categories of bacteria that antibiotics can affect: narrow spectrum
and broad spectrum. Gram positive or gram negative bacteria are the only ones
that narrow spectrum antibiotics can kill. For instance, sodium fusidate only
kills staphylococcal bacteria. Amoxicillin is one example of a broad range
antibiotic, which works against both Gram-positive and Gram-negative bacteria.
Unlike narrow spectrum antibiotics, which are effective against particular
bacterial families, broad spectrum antibiotics are effective against both Gram-
positive and Gram-negative bacteria. Ampicillin is a typical example of a broad-
spectrum antibiotic. The following medical circumstances warrant the use of
broad spectrum antibiotics: empirically (i.e., based on the practitioner's
experience), before the causative bacteria has been formally identified, and
when there is a wide range of potential illnesses and delaying treatment could
result in a potentially serious illness. For instance, in cases of meningitis, if
broad-spectrum medicines are not started, the patient may die within hours. In

into clinical usage after a 40-year break in the discovery of new antibacterial
chemical classes: cyclic lipopeptides (like daptomycin), glycylcyclines (like
tigecycline), and oxazolidinones (like linezolid).
There are two categories of bacteria that antibiotics can affect: narrow spectrum
and broad spectrum. Gram positive or gram negative bacteria are the only ones
that narrow spectrum antibiotics can kill. For instance, sodium fusidate only
kills staphylococcal bacteria. Amoxicillin is one example of a broad range
antibiotic, which works against both Gram-positive and Gram-negative bacteria.
Unlike narrow spectrum antibiotics, which are effective against particular
bacterial families, broad spectrum antibiotics are effective against both Gram-
positive and Gram-negative bacteria. Ampicillin is a typical example of a broad-
spectrum antibiotic. The following medical circumstances warrant the use of
broad spectrum antibiotics: empirically (i.e., based on the practitioner's
experience), before the causative bacteria has been formally identified, and
when there is a wide range of potential illnesses and delaying treatment could
result in a potentially serious illness. For instance, in cases of meningitis, if
broad-spectrum medicines are not started, the patient may die within hours. In
cases of super infections, where several bacterial species are causing illness and
necessitate the use of either a broad-spectrum antibiotic or combination
antibiotic therapy, broad spectrum antibiotics are also used to treat drug-
resistant bacteria that do not respond to other, more narrow spectrum
antibiotics. Three new classes of antibacterial antibiotics have been introduced

that narrow spectrum antibiotics can kill. For instance, sodium fusidate only
kills staphylococcal bacteria. Amoxicillin is one example of a broad range
antibiotic, which works against both Gram-positive and Gram-negative bacteria.
Unlike narrow spectrum antibiotics, which are effective against particular
bacterial families, broad spectrum antibiotics are effective against both Gram-
positive and Gram-negative bacteria. Ampicillin is a typical example of a broad-
spectrum antibiotic. The following medical circumstances warrant the use of
broad spectrum antibiotics: empirically (i.e., based on the practitioner's
experience), before the causative bacteria has been formally identified, and
when there is a wide range of potential illnesses and delaying treatment could
result in a potentially serious illness. For instance, in cases of meningitis, if
broad-spectrum medicines are not started, the patient may die within hours. In
cases of super infections, where several bacterial species are causing illness and
necessitate the use of either a broad-spectrum antibiotic or combination
antibiotic therapy, broad spectrum antibiotics are also used to treat drug-
resistant bacteria that do not respond to other, more narrow spectrum
antibiotics. Three new classes of antibacterial antibiotics have been introduced
into clinical usage after a 40-year break in the discovery of new antibacterial
chemical classes: cyclic lipopeptides (like daptomycin), glycylcyclines (like
tigecycline), and oxazolidinones (like linezolid).

positive and Gram-negative bacteria. Ampicillin is a typical example of a broad-
spectrum antibiotic. The following medical circumstances warrant the use of
broad spectrum antibiotics: empirically (i.e., based on the practitioner's
experience), before the causative bacteria has been formally identified, and
when there is a wide range of potential illnesses and delaying treatment could
result in a potentially serious illness. For instance, in cases of meningitis, if
broad-spectrum medicines are not started, the patient may die within hours. In
cases of super infections, where several bacterial species are causing illness and
necessitate the use of either a broad-spectrum antibiotic or combination
antibiotic therapy, broad spectrum antibiotics are also used to treat drug-
resistant bacteria that do not respond to other, more narrow spectrum
antibiotics. Three new classes of antibacterial antibiotics have been introduced
into clinical usage after a 40-year break in the discovery of new antibacterial
chemical classes: cyclic lipopeptides (like daptomycin), glycylcyclines (like
tigecycline), and oxazolidinones (like linezolid).
There are two categories of bacteria that antibiotics can affect: narrow spectrum
and broad spectrum. Gram positive or gram negative bacteria are the only ones
that narrow spectrum antibiotics can kill. For instance, sodium fusidate only
kills staphylococcal bacteria. Amoxicillin is one example of a broad range
antibiotic, which works against both Gram-positive and Gram-negative bacteria.
