Neisseria gonorrhoeae is a human-specific pathogen that causes gonorrhea, the second
most common sexually transmitted infection worldwide. Disease progression, drug …

Gonococci of the colonial types that are associated with virulence, types 1 and 2, have pili
that enable the bacteria both to attach in vitro to human epithelial cells and to resist …

Neisseria gonorrhoeae causes severe exudative urethritis. The exudates from infected
individuals contain large numbers of polymorphonuclear leukocytes (PMN) with ingested …

A double immunofluorescence staining technique is described for differentiation between
cell-attached (extracellular) and ingested (intracellular) bacteria by HEp-2 cells in cell …

We are constantly in contact with a vast array of microorganisms living in our external
environ-ment as well as on our own mucosal surfaces. The overwhelming majority of these …

Some individuals, with severe or recurrent infection with Neisseria species, have been
identified as lacking a component in the terminal attack sequence of complement …

Colonial varieties of Neisseria gonorrhoeae that are associated with virulence, types 1 and
2, were more resistant to phagocytosis by rabbit exudative polymorphonuclear leukocytes …

Previous studies have indirectly shown that type 1 gonococci are more resistant to
phagocytosis by human neutrophils (PMN) than type 3 gonococci. Using phase contrast …

Neisseria gonorrhoeae is a common bacterial sexually transmitted infection. Like all Gram-
negative bacteria, the outer membrane of the gonococcus is rich in endotoxin, a known …

Addition of iron componds to inocula of the relatively avirulent T3 or T4 colony types of
gonococci increased their lethality for chicken embryos after intravenous inoculation but had …
