Beta-Lactam Antibiotics and Vancomycin Beta-lactam antibiotics
Anti-bacterial drugs have “selective toxicity”, that is they interact with a target present on the bacterial cell, the prokaryote, that is not present in the mammalian host, the eukaryote. For the ß-lactam drugs, this target is the cell wall. Mammalian cells lack cell walls, which for the bacteria are a critically important barrier protecting the organism from not only the vagaries of osmotic s...
متن کاملThe Survey of Genes Encoding Beta-Lactamases, in Escherichia Coli Resistant to Beta-Lactam and Non-Beta-Lactam Antibiotics
Objective(s) Resistance to the new generation of cephalosporins which is mediated by Extended-Spectrum beta-lactamases (ESBLs) has been found among Escherichia coli isolates throughout the world. These resistance genes and their producers, the micro-organisms carrying beta-lactamases, are responsible for serious clinical and therapeutic problems among inpatients and it is necessary to pay more...
متن کاملInoculum effect of new beta-lactam antibiotics on Pseudomonas aeruginosa.
The degree of the inoculum effect shown by the new beta-lactam antibiotics with Pseudomonas aeruginosa was investigated, and the antibiotics were divided into three groups based upon the observations. The group 1 antibiotics (cefotaxime, moxalactam, cefoperazone, azlocillin, piperacillin, and aztreonam) demonstrated a large inoculum effect, were poorly bactericidal, produced aberrant, elongated...
متن کاملChemistry of Beta Lactam Antibiotics
Humans have been plagued with the threat of bacterial infection since before the dawn of recorded history, and have thus always had a keen interest in finding a suitable treatment for these maladies. In the early part of the 19th century, colonial Americans were fearful of death by bacterial infections that are now considered routine, and usually inquired about one another's health in their let...
متن کاملEffect of temocillin in combination with other beta-lactam antibiotics.
The antibacterial interactions of temocillin with other beta-lactams were tested by checkerboard combination in Mueller-Hinton agar against 146 strains of members of the family Enterobacteriaceae, 35 Pseudomonas aeruginosa strains, and 35 Staphylococcus aureus strains. Most combinations showed a moderate degree of synergism. In only one Klebsiella strain was minor antagonism observed between te...
