Newborn infants with "early-onset" disease due to group B beta hemolytic streptococcus were studied over a 40-month period. Clinical presentations included asymptomatic bacteremia, mild transient illness, respiratory distress, meningitis, and overwhelming sepsis. Chronologically, 18 were ill at birth; 10 became ill after a symptom-free period; and four were asymptomatic. Sixty-six percent of the cases weighted less than 2500 grams, and 56% were born to mothers whose amniotic membranes were ruptured for over 20 hours. All 15 of the deaths occurred in low birth weight infants who were criticially ill from birth. A review of 128 consecutive deliveries of infants weighing under 2000 grams revealed 28 cases with prolonged ruptured membranes, and three of these 28 infants developed group B streptococcal infection. The infant of the colonized gravid woman in premature labor or with prolonged ruptured membranes is clearly at risk, and these results suggest that the management of "early-onset" disease should begin prior to delivery.

Cefamandole nafate was effective in the treatment of a variety of infections caused by Staphylococcus aureus, Streptococcus pyogenes group A, Streptococcus pneumoniae, and Haemophilus influenzae in infants and children. The infections included periorbital cellulitis and ethmoiditis, bacteremia, cellulitis, pneumonia, and lymphadenitis. In vitro, cefamandole was effective in inhibiting the growth of H. influenzae isolated from blood or cerebrospinal fluid of patients with meningitis or sepsis. In two patients rash developed and cefamandole was discontinued. Other significant adverse effects were not noted.

Intra-abdominal sepsis that involves multiple aerobic and anaerobic bacteria derived from the colonic flora was studied in Wistar rats to determine the relative roles of various microbial species. The rats challenged with pooled colonic contents showed a biphasic disease. Initially, there was acute peritonitis, Escherichia coli bacteremia, and high mortality. In rats that survived this acute peritonitis stage, intra-abdominal abscesses developed, and anaerobic bacteria were the preponderant organisms. Subsequent experiments showed that antibiotics directed against coliforms prevented mortality, whereas agents active against anaerobes reduced the incidence of abscesses. Challenges with Escherichia coli alone produced bacteremia and death, whereas pure cultures of Bacteroides fragilis caused intra-abdominal abscesses. These observations suggest that both coliforms and anaerobes are important pathogens in intra-abdominal sepsis, although the different types of microbes appear to play distinctive roles in the sequence of pathological events.

In the modern hospital gram negative bacteremia and the associated condition of septic shock are common occurrences. In the United States the estimated incidence of gram negative bacteremia ranges from 71,000 to 330,000 cases annually. Fatalities attributed to this disease are between 18,000 and 132,000 each year. Sepsis is defined as a systemic disease caused by microorganisms or their products in the blood. Bacteremia is the presence of viable organisms in the circulation. Gram negative bacteremia in the critically ill patient is synonymous with gram negative sepsis. Septic shock is a clinical syndrome characterized by circulatory insufficiency and inadequate tissue perfusion. Septic shock is associated primarily although not exclusively with gram negative bacilli. Focus is on predisposing factors, microbiology, pathophysiology, and the 4 components of therapy -- antibiotics, volume replacement, steroids, and surgical drainage. The underlying illness of the patient is the primary factor determining the outcome of an episode of gram negative bacteremia. Patients with a life threatening disorder have a very poor prognosis, while sepsis in a previously healthy person carries a good prognosis. The overall mortality in gram negative bacteremia is 25%. When septic shock develops, the mortality increases to 50-60%. Appropriate antibiotics that are synergistic against the infecting organism can decrease the mortality, but the overwhelming infleunce of host factors in predicting the outcome suggests that prevention and early treatment are the best means of decreasing mortality.

The medical records of 293 patients who underwent renal transplantation were analyzed for the occurrence of Streptococcus pneumoniae and Haemophilus influenzae infections in relation to splenectomy. Splenectomy was done in 236 (81%) graft recipients before or concomitant with transplantation. Bacteremia developed in five and fulminant sepsis in two from 3 to 32 months after splenectomy. No serious infections with these organisms occurred in the nonsplenectomy group. These results suggest that asplenia may be an additional factor predisposing transplant patients to serious infection. Prevention of these serious pneumococcal infections may be possible with polyvalent pneumococcal vaccine.

A prospective study of 390 indwelling central venous catheters placed by way of the subclavian route identified bacteremia and tracheostomy as the only significant variables associated with the colonization of the catheters by pathogenic microorganisms. Catheter-related sepsis was likely in only 3 of 33 episodes of proved bacteremia. Detailed statistical analyses of other potential contaminating factors revealed no significant correlations.

The Limulus test was applied to determine bacterial endotoxemia in 42 patients suspected of having septicemia. Hemocultures were practiced simultaneously. A comparative study is made of the two presently most commonly recommended tests for neutralizing the factors inhibiting the endotoxin-amebocyte reaction. According to our results the dilution of plasma in isotonic saline solution is preferable; we obtained a sensitivity of determination of 0.0001 micrograms of E. coli endotoxin per ml of plasm. Seventeen cases of bacteriemia were diagnosed, only one of which with sepsis due to Serratia marcescens responded positively to the limulus test. The test was positive in three of the remaining 25 patients. Two of them had liver failure. The basic role that liver failure plays in the high level of endotoxin in the blood is discussed. The prognostic value of this test and the low correlation between bacteremia and endotoxemia are also commented on

In a 20-day-old female infant, bacteremia, osteomyelitis, and pyogenic arthritis developed due to infection with group B streptococcus, type Ic. She had an unusual clinical presentation with overwhelming sepsis and acute congestive heart failure.

We report three mildly ill infants who had meningococcal bacteremia and in whom meningitis or fulminant septicemia never developed. The infants were observed during a three-month period. Two of these infants had pneumonia, as evidenced by infiltrates on chest roentgenogram. The serogroups of the organisms isolated were B, Y, and 135. In none of the infants could specific bactericidal antibody be demonstrated in acute or convalescent serum.

Bacteremia following endoscopy of the gastrointestinal tract in patients with impaired resistance even fatal septicemia has been reported. Transmission of pathogenic bacterias via endoscopes has been described. We could demonstrate a considerable high number of gramnegative bacteria obtained from biopsy channel of fiberendoscopes after conventionell cleaning of the instruments. In seven different endoscopy units we found high bacterial contamination of all 22 fiberendoscopes. Pseudomonas aeruginosa in concentrations up to 4 X 10(6)/ml was cultivated on the instruments including cleaning utilities (flasks etc., Table 1). The new apparatus we demonstrate here has the advantage of cleaning and disinfecting the endoscopes. One or two endoscopes are placed into a U-shaped pipe which is interconnected with a pumping system. In this automatic apparatus a disinfectant which recycles through all channels is used (Fig. 1). We investigated solutions of 2% glutardialdehyde, of 5% succindialdehyde respectively 1% peracetic acid. Disinfection of instruments was effective. No bacteria could be detected in material obtained from biopsy channels, HBsAg also could not be detected on the instruments after this procedure. The use of dialdehyde is recommended.
