食品伙伴網(wǎng)訊 據(jù)美國(guó)食品安全新聞網(wǎng)報(bào)道，去年5月加拿大卑詩省出現(xiàn)了一種罕見的沙門氏菌菌株，名為阿格伯尼沙門氏菌（Salmonella  Agbeni），它不同于鼠傷寒沙門氏菌和腸炎沙門氏菌，在北美地區(qū)非常罕見。加拿大衛(wèi)生當(dāng)局已對(duì)此種罕見的病菌展開了調(diào)查。

    Rare Salmonella Strain Sickened 8 in British Columbia Last Year
   
    Outbreak study yields lessons about investigation techniques 
    
    Salmonella  Agbeni -- unlike strains such as S. Enteriditis or S. Typhumurium -- is rarely responsible for human illness in North America. But in May of last year, this serotype sickened 8 people in British Columbia, causing illnesses that were unusual enough to prompt a special investigation into the outbreak.
        
    The resulting study was published in the September 2012 issue of Emerging Infectious Diseases.
        
    While researchers were unable to pinpoint the source of the bacteria, they say that the unique characteristics of the outbreak -- including an abnormally long incubation period and a high percentage of urinary tract infections -- offer valuable lessons for future Salmonella investigations.
        
    During this outbreak, victims began experiencing symptoms 5 -7 days after being exposed to the bacteria, marking an unusually long incubation period for Salmonella, which normally causes illness between 6 and 72 hours after ingestion. This fact suggests that investigators may need to reach farther back in time when looking for common exposures among victims, says the study.
        
    Health officials currently question Salmonella patients about what they ate in the 3 days prior to illness, say the authors. But this outbreak suggests that this time frame may need to be expanded, they note.   
        
    In this case, that 3-day window didn't include the event that turned out to be the likely source of infection for the majority of the B.C. patients -- a wedding attended by 7 of the 8 victims.
