Usage:
Ampicillin is closely related to
amoxicillin, another type of penicillin, and both are
used to treat urinary tract infections, otitis media,
uncomplicated community-acquired pneumonia, Haemophilus
influenzae, salmonellosis and Listeria meningitis.
Ampicillin is used with flucloxacillin in the
combination antibiotic co-fluampicil for empiric
treatment of cellulitis; providing cover against Group A
streptococcal infection whilst the flucloxacillin acts
against the Staphylococcus aureus bacterium. Of concern
is the number of bacteria that become resistant to
Ampicillin necessitating combination therapy or use of
other antibiotics.
All Pseudomonas and most strains of
Klebsiella and Aerobacter are considered resistant.
An ampicillin resistance gene is commonly
used as a selectable marker in routine biotechnology. Due to
concerns over horizontal gene transfer to pathogenic
organisms in the wild, the European Food Safety Authority
restricts use of this gene (among other resistance genes) in
commercial genetically modified organisms. The gene
responsible for degrading Ampicillin is called Beta
Lactamase, in reference to the beta-lactam structure of
Ampicillin and related drugs.
Package and Storage:
Ampicillin is packed in 25kg fiber drum
with shelf life 3 years.
