Morganella morganii , the most histaminogenic bacteria in chilean mackerel, was isolated and used to study the effect of temperature on h istamine production in this fish. Growth and histamine production rates at different initial pH (4.0, 5.5, 6.0, 7.0) and temperatures (10, 15, 20, 30 °C) were studied in batch cultures of M. morganii in a synthetic medium (TSBH2% histidine). An Arrheniustype...

Although somewhat fewer than last year, the studies of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) were certainly intriguing at this year’s American Urological Association (AUA) meeting. There was a renewed interest in the role of bacteria in the condition, although the story may be much more complicated than pointing to one disease-causing bacterium. One study showed that certai...

Biogenic amines (BAs) are considered a potential microbiological toxicological hazard in aged cheese. Risk mitigation strategies include good hygiene practice measures, thermal treatment of milk and the use competitive dairy cultures. The aim this study was to evaluate amount BAs—tryptamine, ?-phenylethylamine, putrescine, cadaverine, histamine, tyramine, spermidine spermine—in core rind cheese...

in the present study, the effects of intracerebroventricular (icv) administration of normal saline (control), histamine, mepyramine (a histamine h1-receptor antagonist) and ranitidine (a histamine h2-receptor antagonist) were investigated on the formalin-induced pain in rabbits. subcutaneous (sc) injection of a formalin (100 μl, 5%) solution into the ventral surface of the right hind paw was pe...
