The combination of amoxicillin and gentamicin has synergistical action against a wide range of infections caused by both Gram-positive (e.g. Staphylococcus spp., Streptococcus spp. and Corynebacterium spp.) and Gram-negative (e.g. E.coli, Pasteurella spp., Salmonella spp. and Pseudomonas spp.) bacteria in cattle and swine. Amoxicillin inhibits mainly in Gram-positive bacteria the cross-linkage between the linear peptidoglycan polymer chains that make up a major component of the cell wall. Gentamicin binds to the 30S subunit of the ribosome of mainly Gram-negative bacteria, thereby interrupting protein synthesis. Excretion of Biogenta occurs mainly unchanged via urine, and to a lesser degree via milk.
Cattle: gastrointestinal, respiratory and intramammary infections caused by bacteria sensitive to the combination of amoxicillin and gentamicin, such as pneumonia, diarrhoea, bacterial enteritis, mastitis, metritis and cutaneous abscesses.
Swine: respiratory and gastrointestinal infections caused by bacteria sensitive to the combination of amoxicillin and gentamicin, such as pneumonia, colibacillosis, diarrhoea, bacterial enteritis and mastitis-metritis-agalactia syndrome (MMA).
Hypersensitivity towards amoxicillin or gentamicin.
