The antibody reaction allows these species to be visualized under a microscope.Extended-spectrum penicillin: The extended-spectrum penicillins are a group of antibiotics that have the widest antibacterial spectrum of all penicillins.Comprehensive Pharmacy Review, Leon Shargel, 6th edition, p917 Some sources identify them with antipseudomonal penicillins,Elsevier's Integrated Review Pharmacology, By Mark Kester, Kelly Dowhower Karpa, Kent E.Meningitis Vaccine ProjectCefuroximeResistome: The resistome is a proposed expression by Gerard D. Wright for the collection of all the antibiotic resistance genes and their precursors in both pathogenic and non-pathogenic bacteria.LactamHaemophilus meningitisOrbifloxacinBeta-lactamaseAmpicillinCSF glucose: (MCnc), (SCnc)External bacterial infection (fish): External bacterial infection is a condition found in fish.ATC code S01: ==S01A Anti-infectives==Combination therapy: Combination therapy or polytherapy is therapy that uses more than one medication or modality (versus monotherapy, which is any therapy taken alone).
