Virulence genetically linked to clonal variation. J. Bacteriol. 85:1274-1279. 1963.-One type, obtained from the purulent exudate of acute gonorrhea was maintained by 69 selective in vitro(More)
OBJECTIVE To validate GE PIXImus2 DXA fat mass (FM) estimates by chemical analysis, to compare previously published correction equations with an equation from our machine, and to determine intermachine variation. RESEARCH METHODS AND PROCEDURES C57BL/6J (n = 16) and Aston (n = 14) mice (including ob/ob), Siberian hamsters (Phodopus sungorus) (n = 15), and(More)
We tested the hypothesis that animals that reduce their body mass in response to decreased photoperiod do not develop diet-induced obesity (DIO) when fed a high-fat diet (HFD). Bank voles (Clethrionomys glareolus) fed a diet with fat content of 13.5% by mass and 28.2% by energy, for 5 weeks, did not develop hyperphagia and were resistant to DIO, consistent(More)
We examined the effect of increasing photoperiod, at a constant low temperature, on the body mass and energy budget of the bank vole Clethrionomys glareolus. Simultaneously, we determined the hypothalamic gene expression of neuropeptides and receptors known to be involved in short-term energy balance. Despite an increase in body mass (approximately 10% of(More)
Relative and absolute resistance to urethral and pharyngeal infection with Neisseria gonorrhoeae persisted for up to two years in male chimpanzees parenterally immunized with a colony type 2 gonococcal antigen. Twelve additional adult males were immunized with either a colony type 1 gonococcal antigen or a sham diluent before being challenged with the(More)
With the use of the agar-gel-diffusion and complement-fixation techniques, it was shown that protoplasm from different gonococcal isolates reacted with sera from some humans with a history of gonorrhea but did not react with "normal" human sera. The reactive antigen(s) could be partially separated from the other antigens by passing the gonococcal protoplasm(More)
Ion-exchange chromatography was used to isolate a fraction from disrupted gonococci which reacts with sera from patients with gonococcal disease in complement-fixation and gel-diffusion tests. This antigenic fraction was shown to be the same as that previously described as having been isolated by gel filtration. The method reported here has the advantage of(More)
