Cloaca (Capri): The Cloaca is an archaeological site on the island of Capri, Italy. It was part of a sewage system built in Roman times.Ewingella americana: Ewingella americana is a Gram-negative rod, and the only species in the genus Ewingella. It was first identified and characterized in 1983.Enterobacter aerogenes: Enterobacter aerogenes is a Gram-negative, oxidase negative, catalase positive, citrate positive, indole negative, rod-shaped bacterium.Beta-lactamaseDiscovery 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.Cronobacter sakazakiiBacitracinMultidrug-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.Citrobacter freundii: Citrobacter freundii is a species of facultative anaerobic. Gram-negative bacilli of the Enterobacteriaceae family.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.Pythium oligandrum: Pythium oligandrum is an Oomycete. It is a parasite of many fungi and other oomycetes including Botrytis, Fusarium and Phytophthora.Exogenous 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.Klebsiella pneumoniaMycena fonticola: Mycena fonticola is a species of fungus in the Mycenaceae family. First reported in 2007, it is known only from central Honshu, in Japan, where it grows on dead leaves and twigs in low-elevation forests dominated by oak trees.Citrobacter amalonaticus: Citrobacter amalonaticus is a Gram-negative species of bacteria, a known human pathogen: it can cause neonatal meningitis and potentially gastroenteritis. It has been known to infect the urinary tract.CefotaximeDNA/RNA non-specific endonuclease: In molecular biology, enzymes in the DNA/RNA non-specific endonuclease family of bacterial and eukaryotic endonucleases share the following characteristics: they act on both DNA and RNA, cleave double-stranded and single-stranded nucleic acids and require a divalent ion such as magnesium for their activity. A histidine has been shown to be essential for the activity of the Serratia marcescens nuclease.Triparental mating: Triparental mating is a form of Bacterial conjugation where a conjugative plasmid present in one bacterial strain assists the transfer of a mobilizable plasmid present in a second bacterial strain into a third bacterial strain. Plasmids are introduced into bacteria for such purposes as transformation, cloning, or transposon mutagenesis.Escherichia fergusonii: Escherichia fergusonii is a Gram-negative, rod-shaped species of bacterium. Closely related to the well-known species Escherichia coli, E.Resistome: 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.Carbapenem: Carbapenems are antibiotics used for the treatment of infections known or suspected to be caused by multidrug-resistant (MDR) bacteria. Their use is primarily in people who are hospitalized.E. coli nitroreductase: E. coli nitroreductase is a flavoprotein found in the bacteria Escherichia coli.Ferric uptake regulator family: In molecular biology, the ferric uptake regulator (FUR) family of proteins includes metal ion uptake regulator proteins. These are responsible for controlling the intracellular concentration of iron in many bacteria.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.Infection Control and Hospital Epidemiology: Infection Control and Hospital Epidemiology is a peer-reviewed medical journal published by the University of Chicago Press. It publishes research on control and evaluation of the transmission of pathogens in healthcare institutions and on the use of epidemiological principles and methods to evaluate and improve the delivery of care, including infection control practices, surveillance, cost-benefit analyses, resource use, occupational health, and regulatory issues.Anaerobacter: Anaerobacter are a genus of Gram-positive bacteria related to Clostridium. They are anaerobic chemotrophs and are unusual spore-formers as they produce more than one spore per bacterial cell (up to five spores).DNA sequencer: A DNA sequencer is a scientific instrument used to automate the DNA sequencing process. Given a sample of DNA, a DNA sequencer is used to determine the order of the four bases: G (guanine), C (cytosine), A (adenine) and T (thymine).CefoperazoneColes PhillipsAztreonamSerratia infection: Serratia infection refers to a disease caused by a species in the genus Serratia.TigemonamLactamCefoxitinPanipenemTrinitrotolueneGram-negative bacterial infection: Gram-negative bacterial infection refers to a disease caused by gram-negative bacteria. One example is E.Klebsiella oxytoca: Klebsiella oxytoca is a Gram-negative, rod-shaped bacterium that is closely related to K. pneumoniae, from which it is distinguished by being indole-positive; it also has slightly different growth characteristics in that it is able to grow on melezitose, but not 3-hydroxybutyrate.Pulsenet: PulseNet is a network run by the Centers for Disease Control and Prevention (CDC) which brings together public health and food regulatory agency laboratories around the United States.http://www.ButylparabenSulfacetamide/sulfurList of butterflies of Algeria: This is a list of butterflies of Algeria. About 121 species are known from Algeria.External bacterial infection (fish): External bacterial infection is a condition found in fish.CefalexinCefteramPiperacillinOrbifloxacinExtended-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.ATC code S01: ==S01A Anti-infectives==AmpicillinReplica plating: 350px|right|thumb|[[Negative selection (artificial selection)|Negative selection through replica plating to screen for ampicillin sensitive colonies]]
