From the Guidelines
For dog bite infections requiring intravenous antibiotics, ampicillin-sulbactam 1.5–3.0 g every 6–8 h is the preferred first-line treatment. This recommendation is based on the guidelines provided by the Infectious Diseases Society of America in 2014 1. The choice of antibiotic is crucial in managing dog bite infections, as they can introduce a polymicrobial mix of aerobic and anaerobic bacteria, including Pasteurella species, Streptococcus, Staphylococcus, and various anaerobes.
- Key considerations for IV antibiotic selection include:
- Broad-spectrum coverage against both aerobic and anaerobic bacteria
- Activity against common dog bite pathogens such as Pasteurella multocida
- Consideration of potential resistance patterns, such as methicillin-resistant Staphylococcus aureus (MRSA)
- Alternative IV antibiotic options may include piperacillin-tazobactam 3.37 g every 6–8 h or a combination of ceftriaxone and metronidazole, although these may have limitations in their coverage against certain pathogens 1.
- The duration of IV antibiotic treatment typically ranges from 5-14 days, depending on the severity of the infection, with consideration for switching to oral antibiotics once clinical improvement occurs.
- In addition to antibiotic therapy, proper wound care, including thorough irrigation, debridement of devitalized tissue, and tetanus prophylaxis as needed, is essential for managing dog bite infections.

From the Research
IV Antibiotic for Dog Bite
There are no research papers to assist in answering this question, as the provided studies do not discuss IV antibiotics or dog bites.
- The studies 2 and 3 focus on different topics, including energy metabolism and cytochrome P-450, and do not provide relevant information for treating dog bites with IV antibiotics.
- The study 2 discusses the effects of hemorrhagic shock and hypoxemia on energy metabolism, while the study 3 examines the electron paramagnetic resonance spectra of mitochondrial and microsomal cytochrome P-450 from the rat adrenal.
- Neither study provides guidance on the use of IV antibiotics for dog bites.
