We compared antimicrobial resistance patterns of Salmonella enterica serovar Typhimurium (ST) of isolates from humans (n = 715) and cattle (n = 378) in the Pacific Northwest from 1982 through 1997. The major changes in antimicrobial resistance can be attributed to the widespread clonal dissemination of multidrug-resistant definitive phage type 104 ST.

The biosynthesis of caldariellaquionone (CQ) was studied in species of Sulfolobus by measuring the incorporation of stable isotopically labeled tyrosines into CQ. By feeding a series of tyrosines labeled with deuterium or 13C and then measuring the extent and position at which label was incorporated into CQ by mass spectrometry, it was shown that more than 95% of the label was incorporated into the benzo[b]thiophen-4,7-quinone moiety of CQ. From the labeling experiments, it is concluded that the benzo[b]thiophen-4,7-quinone is derived as an intact unit from all of the carbons of tyrosine except C-1.

In this report, we describe some of the characteristics of the Comamonas testosteroni B-356 biphenyl (BPH)-chlorobiphenyl dioxygenase system, which includes the terminal oxygenase, an iron-sulfur protein (ISPBPH) made up of an alpha subunit (51 kDa) and a beta subunit (22 kDa) encoded by bphA and bphE, respectively; a ferredoxin (FERBPH; 12 kDa) encoded by bphF; and a ferredoxin reductase (REDBPH; 43 kDa) encoded by bphG. ISPBPH subunits were purified from B-356 cells grown on BPH. Since highly purified FERBPH and REDBPH were difficult to obtain from strain B-356, these two components were purified from recombinant Escherichia coli strains by using the His tag purification system. These His-tagged fusion proteins were shown to support BPH 2,3-dioxygenase activity in vitro when added to preparations of ISPBPH in the presence of NADH. FERBPH and REDBPH are thought to pass electrons from NADH to ISPBPH, which then activates molecular oxygen for insertion into the aromatic substrate. The reductase was found to contain approximately 1 mol of flavin adenine dinucleotide per mol of protein and was specific for NADH as an electron donor. The ferredoxin was found to contain a Rieske-type [2Fe-2S] center (epsilon 460, 7,455 M-1 cm-1) which was readily lost from the protein during purification and storage. In the presence of REDBPH and FERBPH, ISPBPH was able to convert BPH into both 2,3-dihydro-2,3-dihydroxybiphenyl and 3,4-dihydro-3,4-dihydroxybiphenyl. The significance of this observation is discussed.
