The inducers 1,3-diaminopropane and spermidine produce a drastic increase in the expression of the penicillin biosynthetic genes for prolonged time, mediated by the laeA regulator.
Fungal Genet. Biol. 49(12) , 1004-13, (2012) We described previously that an autoinducer molecule, identified as 1,3-diaminopropane (1,3-DAP), is secreted by Penicillium chrysogenum and Acremonium chrysogenum. Using pH-controlled fermentor cultures we have observed in this work that 1,3-DAP and spermidi... |

[Revival of selected well-tried antibiotics. Special features of the antiinfective agents penicillin G, fosfomycin, aztreonam and colistin].
Med. Monatsschr. Pharm. 35(10) , 367-77, (2012) Although a worldwide increasing incidence of bacterial infections with panresistant pathogens may need innovative antiinfective agents, no breakthrough developments can be expected in the near future. As a consequence, well-tried antibiotics like aztreonam, f... |

Effect of 3',5'-cyclic diguanylic acid in a broiler Clostridium perfringens infection model.
Poult. Sci. 92(10) , 2644-50, (2013) In an effort to explore strategies to control Clostridium perfringens, we investigated the synergistic effect of a ubiquitous bacterial second messenger 3',5'-cyclic diguanylic acid (c-di-GMP) with penicillin G in a broiler challenge model. All chicks were in... |

Comparing a combination of penicillin G and gentamicin to a combination of clindamycin and amikacin as prophylactic antibiotic regimens in prevention of clean contaminated wound infections in cancer surgery.
J. Egypt. Natl. Canc. Inst. 25(1) , 31-5, (2013) Appropriate antibiotic selection and timing of administration for prophylaxis are crucial to reduce the likelihood of surgical site infection (SSI) after a clean contaminated cancer surgery. Our aim is to compare the use of two prophylactic antibiotic (PA) re... |

Intrapartum antibiotics for known maternal Group B streptococcal colonization.
Cochrane Database Syst. Rev. 1 , CD007467, (2013) Maternal colonization with group B streptococcus (GBS) during pregnancy increases the risk of neonatal infection by vertical transmission. Administration of intrapartum antibiotic prophylaxis (IAP) during labor has been associated with a reduction in early on... |

Fast determination of antibiotics in whole blood.
Clin. Microbiol. Infect. 19(9) , 869-74, (2013) There is a need for analytical methods capable of monitoring blood antibiotic levels in real time. Here we present a method for quantifying antibiotic levels in whole blood that does not require any sample pretreatment. The tests employ the enzyme penicillina... |

Determination of penicillin G in milk samples using its effect on cloud point extraction of triiodide ion.
J. AOAC Int. 97(4) , 1225-9, (2014) A cloud point extraction (CPE) method for determination of trace amounts of penicillin G by spectrophotometry based on its effect on the triiodide ion (I3(-)) has been developed. Penicillin G is converted to the corresponding penicilloic acid by carrying out ... |
