Precast, prestressed concrete box girders are commonly used as superstructure components for short and medium span bridges. Their configuration and typical side-by-side placement make large portions of these elements inaccessible for visual inspectio

In vibration-based damage detection, changes to structural modal properties are tracked over time in order to infer the current state of damage or deterioration. As such, the ability to obtain reliable estimates of modal parameters, particularly natu

Computer searches were carried out of the gonococcal and meningococcal genome databases for previously unknown members of the TonB-dependent family (Tdf) of outer-membrane receptor proteins. Seven putative non-contiguous genes were found and three of

The molecular weight heterogeneities of Tbp1 and Tbp2 among a panel of 45 gonococcal isolates were assessed. The tbpB genes from four of these strains were sequenced to characterize the Tbp2 sequence diversity among gonococci. By expressing truncated

The majority of in vitro-grown Neisseria gonorrhoeae strains were unable to use hemoglobin as the sole source of iron for growth (Hgb-), but a minor population was able to do so (Hgb+). The ability of Hgb+ gonococci to utilize hemoglobin as the iron

The pathogenic Neisseria spp. produce a number of iron-regulated gene products that are thought to be important in virulence. Iron-responsive regulation of these gene products has been attributed to the presence in Neisseria spp. of the Fur (ferric u

Neisseria gonorrhoeae acquires iron (Fe) efficiently from lactoferrin (LF). A 103-kDa gonococcal outer membrane LF-binding protein (Lbp) was identified previously. We isolated the structural gene lbpA for Lbp1 by screening a gonococcal library for a

Antioxidant enzymes are thought to be important for the survival of pathogenic Neisseria species. We isolated a glutathione peroxidase-related gene (gpxA) from Neisseria meningitidis FAM20. The N. meningitidis glutathione peroxidase homolog was 49 to

Bacterial infections of the genital tract (gonorrhea, chlamydia, chancroid, syphilis) are common and cause significant morbidity. Their importance is heightened by recent appreciation of their roles in facilitation of transmission of the human immuno

Sexually transmitted diseases have afflicted humankind for millennia, based on references to apparent gonorrhea or nongonococcal urethritis in the Old Testament (Leviticus). For most of history there has been no means of specific diagnosis, and clini
