Scientists from DTU have discovered that a combination of two common antibiotics can eliminate multi-drug resistant E. coli causing urinary tract infections; this combination treatment could become an effective measure against antibiotic resistance A group of scientists in Denmark is trying to get one step ahead in the battle against antibiotic resistance. Today, many disease-causing bacteria acquire resistance genes, which make antibiotic treatment ineffective. Especially, one gene, CTX-M-15, encoding an extended spectrum beta-lactamase (ESBL) can lead to resistance in E. The team of researchers at DTU have shown that a cocktail of two common antibiotics, mecillinam and cefotaxime, can make these specific multi-resistant E. coli (extended spectrum beta-lactamase, ESBL) sensitive to treatment again. The development of resistance towards either mecillinam or cefotaxime leads to concurrent sensitivity to the other drug - a phenomenon called collateral sensitivity. The study has been published in Nature Communications. The molecular formula is C16H19N3O5S•3H2O and the molecular weight is 419.45. The chemical structure is: Amoxicillin acts by inhibiting bacterial cell wall synthesis. Lack of bacterial cell wall results in death due to lysis of bacteria. So amoxicillin is useful only for actively growing and cell wall synthesizing bacteria. Food does not interfere with absorption of amoxicillin. It crosses the placenta; small amounts are distributed into breast milk. Amoxicillin is excreted mainly by kidney and by hepatic metabolism. Its excretion can be delayed by concomitant administration of probenecid.

Class: Aminopenicillins Chemical Name: [2S-[2α,5α,6β(S*)]]-6-[[Amino(4-hydroxyphenyl)acetyl]amino]-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid trihydrate CAS Number: 61336-70-7 Medically reviewed on Sep 3, 2018 AAP, AAFP, CDC, and others consider amoxicillin the drug of first choice for initial treatment of AOM, unless the infection is suspected of being caused by β-lactamase-producing bacteria resistant to the drug, in which case the fixed combination of amoxicillin and clavulanate is recommended for initial treatment. AAP, AAFP, and others recommend watchful waiting for 3 months from date of effusion onset or diagnosis in those 2 months to 12 years of age who are not at risk for speech, language, or learning problems; some suggest a short course of anti-infectives may be considered for possible short-term benefits when parent and/or caregiver expresses a strong aversion to impending surgery. Baltimore: Williams & Wilkins; 198-341, 418-73, 607-722. AAP, IDSA, and AHA recommend a penicillin regimen (i.e., 10 days of oral penicillin V or oral amoxicillin or single dose of IM penicillin G benzathine) as treatment of choice for S. pyogenes pharyngitis and tonsillitis; Alternative regimens recommended for retreatment include a narrow-spectrum oral cephalosporin, oral clindamycin, oral fixed combination of amoxicillin and clavulanate, oral macrolide, or IM penicillin G benzathine. Consider that multiple, recurrent episodes of symptomatic pharyngitis within a period of several months to years may indicate that patient is a long-term pharyngeal carrier of S. pyogenes experiencing repeated episodes of nonstreptococcal (e.g., viral) pharyngitis. Eradication of the carrier state may be desirable in certain situations (e.g., community outbreak of acute rheumatic fever, acute poststreptococcal glomerulonephritis, or invasive S. pyogenes pharyngitis in a closed or partially closed community; multiple episodes of documented symptomatic S. Bactericidal action of β-lactam antibiotics on Escherichia coli with particular reference to ampicillin and amoxycillin. coli) is a gram-negative, rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms (endotherms). coli strains are harmless, but some serotypes are pathogenic and can cause serious food poisoning in humans, and are occasionally responsible for product recalls. and fecal–oral transmission is the major route through which pathogenic strains of the bacterium cause disease. Cells are able to survive outside the body for a limited amount of time, which makes them ideal indicator organisms to test environmental samples for fecal contamination. The bacterium can also be grown easily and inexpensively in a laboratory setting, and has been intensively investigated for over 60 years. coli is the most widely studied prokaryotic model organism, and an important species in the fields of biotechnology and microbiology, where it has served as the host organism for the majority of work with recombinant DNA. German paediatrician and bacteriologist Theodor Escherich discovered E. coli in 1885, The O antigen is used for serotyping E. coli and these O group designations go from O1 to O181, with the exception of some groups which have been historically removed, namely O31, O47, O67, O72, O93 (now K84), O94, and O122; groups 174 to 181 are provisional (O174=OX3 and O175=OX7) or are under investigation (176 to 181 are STEC/VTEC).

Zürich. 2010 waren 28% der E. coli resistent gegenüber Cotrimoxazol, 16% gegenüber den Chinolonen und 16% gegenüber Amoxicillin/Clavulansäure. The molecular formula is C16H19N3O5S•3H2O and the molecular weight is 419.45. The chemical structure is Mechanism of action. Amoxicillin acts by inhibiting bacterial cell wall synthesis.
