Yersinia
enterocolitica was recovered from the blood of an infant with
sepsis
and fever but with few gastrointestinal symptoms. The age of this patient was unusual as septicemia owing to this organism has most frequently been seen in adults. Because of the absence of digestive symptoms, it is uncertain what the portal of entry of the organism might have been.
Yersinia
enterocolitica is not often recognized, either because of difficulties in identification or because it may not be recognized as a human pathogen.

The murine monoclonal IgM antibody E5 has been shown to significantly reduce the mortality and morbidity of patients with Gram-negative
sepsis
in a multicenter randomized placebo-controlled clinical trial. The in vitro binding characteristics of monoclonal antibody (mAb) E5 were studied using highly purified smooth lipopolysaccharide (LPS) isolated from a variety of clinically relevant, wild-type Gram-negative bacteria. Using a sensitive antibody-capture assay which involves immobilized mAb E5 and a chromogenic Limulus amebocyte lysate (LAL) LPS-detection system, mAb E5 was shown to bind to all 15 smooth LPS preparations tested, including LPS isolated from Escherichia, Klebsiella, Proteus, Pseudomonas, Salmonella, Serratia and
Yersinia
species. When LPS was fractionated according to size by size-exclusion chromatography, mAb E5 was shown to bind to smooth LPS molecules that have long as well as short O-polysaccharide chains. These results confirm and extend those reported previously and demonstrate that the anti-lipid A mAb E5 binds specifically to a diverse spectrum of smooth LPS isolated from wild-type Gram-negative bacteria.

There have been increasing numbers of reports of transfusion-acquired
Yersinia
enterocolitica bacteremia (including several fatal cases). Fifteen units of whole blood were inoculated with various concentrations of Y. enterocolitica serotype 0:3 and processed into AS-3 preserved red cells (RBCs). Consistent growth of the organism was found at inoculum concentrations greater than or equal to 10 colony-forming units per mL. In all 13 units of RBCs that supported the growth of Y. enterocolitica, a darkening in color (due to hemolysis and a decrease in pO2) was observed in the bag. The attached sample segments, which were sealed from the main unit, remained sterile and did not darken. This color change was apparent in all the contaminated units by Day 35, which was 1.5 to 2 weeks after the bacteria were first detected in cultures of the blood. Hence, by comparison of the color of the segment tubing with that of the unit itself, units grossly contaminated with Y. enterocolitica can be identified prior to transfusion. Moreover, review of photographs on file at the Centers for Disease Control revealed this dramatic color change in 2 units of blood that caused transfusion-transmitted
sepsis
(Enterobacter agglomerans and an unidentified gram-negative bacillus, not
Yersinia
sp.), which demonstrated that the color change was not limited to Y. enterocolitica. This method of visual identification of contaminated units of blood could decrease the incidence of posttransfusion bacterial
sepsis
.

From January 1980 to July 1990, the Hospital Infections Program of the Centers for Disease Control conducted 125 on-site epidemiologic investigations of nosocomial outbreaks. Seventy-seven (62%) were caused by bacterial pathogens, 11 (9%) were caused by fungi, 10 (8%) were caused by viruses, five (4%) were caused by mycobacteria, and 22 (18%) were caused by toxins or other organisms. The majority of fungi and mycobacterial outbreaks occurred since July 1985. Fourteen (11%) outbreaks were device related, 16 (13%) were procedure related, and 28 (22%) were product related. The proportion of outbreaks involving products, procedures, or devices increased from 47% during 1980-1985 to 67% between 1986 and July 1990. Recent outbreaks have shown that packed red blood cell transfusion-associated
Yersinia
enterocolitica
sepsis
results from contamination of the blood by the asymptomatic donor; that povidone-iodine solutions can become intrinsically contaminated and cause outbreaks of infection and/or pseudoinfection; and that rapidly growing mycobacteria can cause chronic otitis media, surgical wound infection, and hemodialysis-associated infections. These and other outbreaks demonstrate how epidemiologic and laboratory investigations can be combined to identify new pathogens and sources of infection and ultimately result in disease prevention.

Recent reports of fatal transfusion-associated
Yersinia
enterocolitica
sepsis
prompted a study of the feasibility of adding a question to the routine donor health history as a method of reducing this risk. In three American Red Cross blood centers, 11,323 donors were asked one of two questions about gastrointestinal symptoms during their health history screenings. Affirmative responses were obtained from 0.6 or 4.0 percent of the donors, depending on how the question was asked. In one center, more than 6 percent of donors gave affirmative answers. The efficacy of asking a relatively simple question about gastrointestinal symptoms as a way of preventing Y. enterocolitica should be evaluated further, because relatively large numbers of donors may respond affirmatively. Other methods of reducing the risk of transfusion-associated Y. enterocolitica infection should be pursued.

Septicemia is a rare complication of blood transfusion. This is probably primarily due to the use of sealed disposable containers for blood collection and the storage of red cell-containing components at 4 degrees C. However, despite these measures, septicemia due to blood transfusion continues to occur. We report here a fatal case of
Yersinia
enterocolitica septicemia due to a contaminated unit of red cells which was collected from an apparently healthy, asymptomatic blood donor. The organism grows at cold temperature and multiplies during storage of red blood cell-containing components. Contaminated components do not show any visible abnormalities. The possibility of transfusion-transmitted Y. enterocolitica should be considered in patients who have symptoms of
sepsis
or shock following transfusion.

Between April 1987 and May 1989, the Centers for Disease Control investigated seven cases of transfusion-associated
Yersinia
enterocolitica
sepsis
; four were caused by organisms of serotype O:3, and one each was caused by organisms of serotype O:1,2,3; O:5,27; and O:20. All seven recipients developed septic shock after receiving units of red cells (RBCs) contaminated with Y. enterocolitica; five recipients died. The cases occurred in seven states and were unrelated. There was no evidence for contamination of the RBC units during processing. Six of the seven donors had serologic evidence of recent Y. enterocolitica infection, and it is hypothesized that these donors had asymptomatic bacteremia when they donated the implicated blood. Four of the seven donors reported gastrointestinal illness in the 4 weeks before blood donation, and one donor became ill on the day he donated blood. Y. enterocolitica grows well at 4 degrees C and in the presence of dextrose and iron. If blood is contaminated at the time of collection, storage of the RBCs at 4 degrees C provides an ideal environment for bacterial growth and endotoxin production. These cases demonstrate the need for careful evaluation of patients with transfusion reactions for possible
sepsis
and suggest a need to screen prospective blood donors for mild gastrointestinal illness, including those illnesses not requiring physician evaluation or medication.

Hemochromatosis, or primary iron overload, is a variably expressed genetic metabolic disorder greatly modified by sex, age, diet, and alcohol consumption. Although a diagnosis has been made at the bedside by careful documentation of the slow resolution of subcutaneous iron pigment, clinical diagnosis is frequently overlooked, and even autopsy may fail to reveal hemochromatosis as the cause for cirrhosis. Genetic linkage studies have confirmed the extremely high prevalence of this disorder. Untreated patients may succumb to
sepsis
caused by organisms such as Vibrio vulnificus,
Yersinia
species, and others whose virulence is altered by iron availability.

Since 1987, the Centers for Disease Control investigated six cases of transfusion-associated
sepsis
. All six patients developed septic shock after receiving units of packed erythrocytes (PRBCs) contaminated with
Yersinia
enterocolitica (five patients) and Enterobacter agglomerans (one patient); three of the blood recipients died. We studied the growth and endotoxin production of Y. enterocolitica and E. agglomerans in units of PRBCs stored at 4 degrees C for 60 days. When PRBCs were inoculated with 0.1 to 1.0 CFU of these organisms per ml, both Y. enterocolitica and E. agglomerans entered log-phase growth 2 to 3 weeks after inoculation; generation times were 15 and 22 h, respectively. Endotoxin was first detected at 3 weeks following inoculation, and the concentration paralleled the log phase of growth of the strains tested. These data show that prolonged storage of PRBCs at 4 degrees C provides conditions that allow these two organisms to grow and subsequently produce high concentrations of endotoxin.
