CefotaximeDiscovery and development of cephalosporins: Cephalosporins are a broad class of bactericidal antibiotics that include the β-lactam ring and share a structural similarity and mechanism of action with other β-lactam antibiotics (e.g.Oxacephem: An oxacephem is a molecule similar to a cephem, but with oxygen substituted for the sulfur. They are synthetic compounds not seen in nature.Cephamycin: Cephamycins are a group of beta-lactam antibiotics. They are very similar to cephalosporins, and the cephamycins are sometimes classified as cephalosporins.Beta-lactamaseBacitracinCefoperazoneCeftriaxoneExtended-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.Quellung reaction: The Quellung reaction is a biochemical reaction in which antibodies bind to the bacterial capsule of Streptococcus pneumoniae, Klebsiella pneumoniae, Neisseria meningitidis, Haemophilus influenzae, Page 340 Escherichia coli, and Salmonella. The antibody reaction allows these species to be visualized under a microscope.CefteramEwingella americana: Ewingella americana is a Gram-negative rod, and the only species in the genus Ewingella. It was first identified and characterized in 1983.CefoxitinAztreonamLactamExogenous bacteria: Exogenous bacteria are microorganisms introduced to closed biological systems from the external world. They exist in aquatic and terrestrial environments, as well as the atmosphere.PiperacillinKlebsiella pneumoniaCefuroximePanipenemClavulanic acidResistome: 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.Meningitis Vaccine ProjectAmpicillinMultidrug-resistant gram-negative bacteria: MDRGN bacteria is an abbreviation for multidrug resistant gram-negative bacteria. For hospitalized patients, and especially patients in intensive care units, these bacterial infections pose a serious and (as of 2010) rapidly emerging threat.PGLO: The pGLO plasmid is an engineered plasmid used in biotechnology as a vector for creating genetically modified organisms. The plasmid contains several reporter genes, most notably for the green fluorescent protein (GFP) and the ampicillin resistance gene.List of strains of Escherichia coli: Escherichia coli is a well studied bacterium that was first identified by Theodor Escherich, after whom it was later named.OrbifloxacinExternal bacterial infection (fish): External bacterial infection is a condition found in fish.Information source: An information source is a source of information for somebody, i.e.TobramycinOST4: In molecular biology, OST4 (Dolichyl-diphosphooligosaccharide--protein glycosyltransferase subunit 4) is a subunit of the oligosaccharyltransferase complex.Klebsiella terrigena: Klebsiella terrigena is a Gram-negative bacterial species of the genus Klebsiella. It has primarily been isolated from soil and water samples, but rarely from humans.ATC code S01: ==S01A Anti-infectives==BenzylpenicillinAmikacinGentamicinUreidopenicillin: The ureidopenicillins are a group of penicillins which are active against Pseudomonas aeruginosa.Proteus vulgaris: Proteus vulgaris is a rod-shaped, nitrate-reducing, indole+ and catalase-positive, hydrogen sulfide-producing, Gram-negative bacterium that inhabits the intestinal tracts of humans and animals. It can be found in soil, water, and fecal matter.
