Abstract
We cloned, overexpressed and purified four new DHFRs from the deep-sea bacteria Shewanella violacea (svDHFR), Photobacterium profundum (ppDHFR), Moritella yayanosii (myDHFR) and Moritella japonica (mjDHFR), and compared their structure and function with those of Escherichia coli DHFR (ecDHFR). These...

Abstract
We must also increase our understanding of the drug-resistant mechanisms of bacteria. In this issue we wish to introduce the recent worldwide trend in antimicrobial-resistant bacteria, especially multidrug-resistant bacteria, such as methicillin-resistant Staphylococcus aureus, vancomycin-resistant...

Antimicrobial mechanism of action of surfactant lipid preparations in enteric Gram-negative bacilli.
Abstract
Two surfactant lipid preparations (SLPs) were investigated to determine their mechanism of antimicrobial action. 8N8, a water-in-oil emulsion, and W60C, a liposome, both have bactericidal activity against Gram-positive bacteria and non-enteric Gram-negative bacteria.
