A nursery outbreak of gastroenteritis casued by Escherichia coli 0142/K86/H6 is described. Over a period of nine months, 59 epidemiologically linked cases of diarrhea occurred, including 21 intractable cases with four deaths. The epidemic strain, which was not agglutinated by commerical diagnostic antisera, was isolated from the hands of personnel in five instances directly incriminated hand carriage as the mode of spread. Acquisition of illness, which was especially high among low-birth-weight infants less than 17 days old, did not correlate with any treatment modality investigated and appeared to be related to a host factor. Noninvasive small intestinal colonization, production of enterotoxin, and multiple antibiotic resistance of the epidemic strain were demonstrated and helped to explain the intractability of clinical illness in many infants, despite intensive parenteral antibiotic therapy. Surveys of fecal coliforms on the hands of nursery personnel revealed no change in prevalence after introduction of a policy of "triple" handwashing with 3 percent hexachlorophene soap, but a significant decrease occurred during the use of disposable gloves. The frequent occurrence of E. coli 0142 in throat swabs of affected infants suggested that pharyngeal colonization may serve as an important diagnostic clue in E. coli diarrhea.

Helicobacter cinaedi is an enterohepatic species. It can cause bacteremia, gastroenteritis, and cellulitis, particularly in immunocompromised individuals, such as those with acquired immunodeficiency syndrome, malignancy, or alcoholism. There are no previous reports of H. cinaedi infection in Korea. A 71-yr-old man was admitted to the emergency room because of dyspnea on November 9, 2011. He had undergone splenectomy 3 yr ago because of immune hemolytic anemia. Chest plain radiography revealed bilateral pleural effusion. He developed fever on hospital day (HD) 21. Three sets of blood cultures were taken, and gram-negative spiral bacilli were detected in all aerobic vials. The isolate grew in tiny colonies on chocolate agar after 3-day incubation under microaerophilic conditions. This organism tested positive for catalase and oxidase, and negative for urease. The 16S rRNA gene sequence of this isolate exhibited 99.8% homology with the published sequence of H. cinaedi CCUG 18818(T) (GenBank accession no. ABQT01000054) and 98.5% homology with the sequence of Helicobacter bilis Hb1(T) (GenBank accession no. U18766). The patient was empirically treated with piperacillin/tazobactam and levofloxacin, and discharged with improvement on HD 31. To our knowledge, this is the first report of H. cinaedi bacteremia in an asplenic patient. Asplenia appears to be a risk factor for H. cinaedi bacteremia.
