Broad-spectrum antibiotic focusing on evidence-based approaches to minimize resistance. In humans: In veterinary medicine, co-amoxiclav, (in small animals); penicillin & streptomycin and oxytetracycline (in farm animals); penicillin and potentiated sulfonamides (in horses). Broad-spectrum antibiotic The term broad-spectrum antibiotic can refer to an antibiotic that acts on the two major bacterial groups, gram-positive and gram-negative, or any antibiotic that acts against a wide range of disease-causing bacteria. These medications are used when a bacterial infection is suspected but the group of bacteria is unknown (also called empiric therapy) or when infection with multiple groups of bacteria is suspected. This is in contrast to
Antibiotic Resistance Lab Network Antibiotic Resistance Lab Network The Antibiotic Resistance Lab Network (ARLN) is a group of laboratories of the United States Centers for Disease Control and Prevention established to supplement the work of local and state public health laboratories in the identification and research of antibiotic resistance. It was created as part of the CDC's "National Action Plan for Combating Antibiotic Resistant Bacteria". The network is part of the National Center for Emerging and Zoonotic Infectious Diseases. Laboratories in this network cover seven regions and are located in Maryland, Minnesota, New York, Tennessee, Texas, Washington, and Wisconsin, as part of their state
