background : lactobacilli are the well known friendly bacteria for their probiotic activities against pathogens. the inhibitory activity of different strains of lactobacilli either obtained as commercial products or isolated from human feces was investigated against the clinical isolates of pseudomonas aeruginosa. the isolates were selected as the most resistant strains when challenged with ant...
Infections caused by multi-resistant Gram-negative bacteria, particularly Pseudomonas aeruginosa, are increasing worldwide. In patients with cystic fibrosis (CF), resistance in P. aeruginosa to numerous anti-pseudomonal agents is becoming common. The absence since 1995, of new substances active against resistant Gram-negative bacteria, has caused increasing concern. Colistin, an old antibiotic ...
Aminothiazolylacetamidocephalosporins having 1-carboxyethoxyimino groups were synthesized and found to have excellent antibacterial activities including anti-pseudomonal activity and low toxicities. Among these cephalosporins, ME1228 having (S)-1-carboxyethoxyimino substituent and being combined with an (N-ethyl-4-pyridinio)thiomethyl group at C-3 showed marked therapeutic effects against syste...
BACKGROUND Although the proportion of Pseudomonas aeruginosa infections has reduced after the introduction of antibiotics with anti-pseudomonal effects, P. aeruginosa bacteremia still causes high mortality in immunocompromised patients. This study determined the clinical characteristics and outcomes of P. aeruginosa bacteremia and the antibiotic susceptibilities of strains isolated from febrile...
BACKGROUND Antibiotic exposure is common among children with leukemia. However, limited data exist regarding the risk of Clostridium difficile infection (CDI) across anti-pseudomonal β-lactam antibiotics commonly used for fever and neutropenia. METHODS A multicenter cohort of children with newly diagnosed acute lymphoblastic leukemia (ALL) was established from 43 freestanding children's hospi...
BACKGROUND Lactobacilli are the well known friendly bacteria for their probiotic activities against pathogens. The inhibitory activity of different strains of lactobacilli either obtained as commercial products or isolated from human feces was investigated against the clinical isolates of Pseudomonas aeruginosa. The isolates were selected as the most resistant strains when challenged with anti-...
Quinolone antibacterials, originally derived from anti-malarial compounds, have been developed through side-chain and nuclear manipulation, notably by piperazine and other mono- or bi-cyclic substitutions at the 7 position (giving anti-pseudomonal activity and greater anti-Gram-negative activity) and fluorination at various sites (giving increased anti-Gram-positive activity). The class has now...
