They are vital to bacterial cell wall synthesis and antibiotic resistance.Tympanocentesis: Tympanocentesis is the drainage of fluid from the middle ear usually caused by otitis media, by using a small-gauge needle to puncture the tympanic membrane, also known as the eardrum.ATC code J07: ==J07A Bacterial vaccines==Mycoplasma pneumoniaKetolideAvery–MacLeod–McCarty experimentCefotaximePolysaccharide encapsulated bacteriaColes PhillipsMoraxella catarrhalis: Moraxella catarrhalis is a fastidious, nonmotile, Gram-negative, aerobic, oxidase-positive diplococcus that can cause infections of the respiratory system, middle ear, eye, central nervous system, and joints of humans. It causes the infection of the host cell by sticking to the host cell using a Trimeric Autotransporter Adhesins (TAA).LevofloxacinCeftriaxoneTopoisomerase IV: Topoisomerase IV is one of two type-II topoisomerases in bacteria, the other being DNA gyrase. Like gyrase, topoisomerase IV is able to pass one double-strand of DNA through another double-strand of DNA, thereby changing the linking number of DNA by two in each enzymatic step.SortaseLower respiratory tract infection: Lower respiratory tract infection (LRTI), while often used as a synonym for pneumonia, can also be applied to other types of infection including lung abscess and acute bronchitis. Symptoms include shortness of breath, weakness, fever, coughing and fatigue.TosufloxacinBacteremia: (NOS) |CSF glucose: (MCnc), (SCnc)Discovery 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.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).Bacterial pneumoniaConjugate vaccine: A conjugate vaccine is created by covalently attaching a poor (polysaccharide) antigen to a carrier protein (preferably from the same microorganism), thereby conferring the immunological attributes of the carrier to the attached antigen.Gentamicin protection assay: The gentamicin protection assay or survival assay or invasion assay is a method used in microbiology. It is used to quantify the ability of pathogenic bacteria to invade eukaryotic cells.Virulence: Virulence is, by MeSH definition, the degree of pathogenicity within a group or species of parasites as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host. The pathogenicity of an organism - its ability to cause disease - is determined by its virulence factors.Streptococcus gordonii: Streptococcus gordonii is a Gram-positive bacterium included among some of the initial colonizers of the periodontal environment.

Silent mutations can occur in non-coding regions (outside of genes or within introns), or they may occur within exons.Trimeric autotransporter adhesin: In molecular biology, trimeric autotransporter adhesins (TAAs), are proteins found on the outer membrane of Gram-negative bacteria. Bacteria use TAAs in order to infect their host cells via a process called cell adhesion.Protein primary structure: The primary structure of a peptide or protein is the linear sequence of its amino acid structural units, and partly comprises its overall biomolecular structure.
