Ampicillin for injectable suspension has proved effective in the treatment of many infections previously beyond the spectrum of penicillin therapy. This drug is particularly indicated in the treatment of the following infections caused by susceptible strains of organisms:
Dogs and Cats-Respiratory Tract Infections: Upper respiratory infections, tonsillitis and bronchopneumonia due to hemolytic streptococci, Staphylococcus aureus, Escherichia coli, Proteus mirabilis, and Pasteurella spp.
Urinary Tract Infections due to Proteus mirabilis, Escherichia coli, Staphylococcus spp., hemolytic streptococci and Enterococcus spp.
Gastrointestinal Infections due to Enterococcus spp., Staphylococcus spp. and Escherichia coli.
Skin, Soft Tissue and Post-Surgical Infections: Abscesses, pustular dermatitis, cellulitis and infections of the anal gland, due to Escherichia coli, Proteus mirabilis, hemolytic streptococci, Staphylococcus spp. and Pasteurella spp.
Cattle and calves Including Non-Ruminating (Veal Calves)-Respiratory Tract Infections: Bacterial pneumonia (shipping fever, calf pneumonia and bovine pneumonia) caused by Aerobacter spp., Klebsiella spp., Staphylococcus spp., Streptococcus spp., Pasteurella multocida and E.coli susceptible to ampicillin trihydrate.
