Five infants with pneumococcal sepsis presented with respiratory distress and clinical signs of infection in the first day of life. Although there was no apparent epidemiological relationship among the patients, four of the five were seen within a 12-month period. Pneumonia, prolonged rupture of fetal membranes, and prematurity were features in these patients. Three infants died, two within 12 hours of diagnosis. Streptococcus pneumoniae was isolated from the vagina of three of the mothers; in two, the serotype was identical to that recovered from their infants. Clinical features of neonatal pneumococcal sepsis are similar to those of early-onset group B streptococcal infection. Like the group B Streptococcus, S. pneumoniae acquired from the maternal vagina is a potential life-threatening pathogen in the newborn period.

The intravenous inoculation of adult mice with virulent group B streptococci serotype Ia resulted in fulminating sepsis with extensive colonization of the lungs and kidneys. The time course of the infection lasting 24 to 40 h, extensive pulmonary colonization, and resistance of the type Ia organism to phagocytosis in the absence of specific antibody suggest that mice are an appropriate model for the study of early onset streptococcal infection of human neonates.

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.

An increased morbidity by Streptococcus agalactiae (group B streptococci) during the perinatal period was to be found in some countries since 1961. Six cases of group B streptococcal meningitis were confirmed by the Central Streptococcus Laboratory of the GDR from July to December 1975. Therefore it is necessary to look for group B streptococcal infection in certain cases of diseases of the newborn. In a short review of literature the clinical signs (acute onset with respiratory distress, sepsis or late onset with meningitis), prevalence, source of infection and therapy (ampicillin or a combination of penicillin G and gentamicin) were summarized. The diagnosis is confirmed by isolation of group B streptococci.

When the late Dr. John F. Fulton contracted severe pulmonary coccidioidomycosis in January, 1942, a metastatic lesion posed the threat of further progression and fatal dissemination. The possibility that an untested and generally unavailable antibiotic, penicillin, might be of value in Fulton's illness led his physician, Dr. John Bumstead, to appeal directly to Fulton to obtain this antibiotic, but ostensibly for the benefit of another patient succumbing to hemolytic streptococcal infection. While of no value for Fulton, penicillin was highly successful in the treatment of his other patient and soon of a second one with staphylococcal sepsis and pneumonia. This penicillin, administered in March, 1942, was the first clinical trial of penicillin under the control of the Office of Scientific Research and Development. The unique contribution of Dr. Fulton and of his illness to this event is described.

The development of antibody in response to invasive infection with type III strains of group B Streptococcus was studied in sera from 31 infants and 4 adults by means of a quantitative radioactive antigen-binding assay. Low concentrations of antibody were consistently found in the acute sera of patients who developed clinical illness. Although adults with puerperal sepsis and infants with bone or joint infection uniformly demonstrated significant rises in serum antibody concentration after recovery, much lower levels of antibody were detected in convalescent sera from infants recovering from meningitis or sepsis. The median antibody concentration in sera from 43 parturients with type III strains of group B Streptococcus isolated from vaginal cultures whose neonates failed to develop symptomatic disease was significantly greater than that in sera from 29 mothers of infants with invasive, type III, group B streptococcal infection. Study of paired maternal and cord sera demonstrated a significant correlation between the antibody concentration in a mother's serum and that in her neonate.

Penicillins were studied comparatively on mice with infections caused by pneumococci and streptococci. It was shown that klomethacillin was superior by its chemotherapeutic effect to other penicillins in treatment of pneumococcal septicemia when used subcutaneously or intragastrically. Ampicillin was superior in treatment of streptococcal infection.

A case of right-sided diaphragmatic hernia following group B streptococcal pneumonia and sepsis is reported herein. The clinical course was characteristic. The position of the right hemidiaphragm was initially normal. After an antecedent group B streptococcal infection, an abnormal shadow indicating either pneumonia or a pleural effusion on the chest x-ray was recognized and an elevation of the bowel and liver into the right hemithorax gradually appeared. Repair of the hernia was indicated and the postoperative result was excellent. The relationship between a delayed-onset diaphragmatic hernia and a group B streptococcal infection is still unknown. Increased intrathoracic pressure caused by mechanical ventilation coupled with an abnormal lung compliance due to inflammation may have resulted in the delayed herniation. Among various methods for diagnosis applied, chest x-ray and ultrasonography were noninvasive and useful.

The spread of group A streptococcal infection to close contacts of infected persons is well recognized. With the resurgence of invasive group A streptococcal infections, there is an increased potential for clusters of patients with invasive disease. We reviewed data collected since December 1988 at the Centers for Disease Control (Atlanta) to identify clusters of infection in which one or more patients had invasive disease. Twelve family clusters were identified. Infection in index cases included the toxic shock-like syndrome and septicemia. Infection in family contacts included invasive infections, pharyngitis, or asymptomatic carriage. Most invasive disease occurred in adults, while the majority of noninvasive infections were in children. Five nosocomial clusters with spread of infection from patients to hospital personnel were documented. All index patients had the toxic shock-like syndrome; secondary infections included the toxic shock-like syndrome, pneumonia, bullous cellulitis, lymphangitis, and pharyngitis. Clusters of invasive infections also were identified in five nursing homes. Pneumonia, cutaneous infections, and the toxic shock-like syndrome occurred most commonly. Clustering by nursing home unit occurred in three outbreaks. In hospitals and nursing homes, improved infection control will likely decrease secondary spread; in families, spread of disease may be prevented by identifying and treating those harboring the organism or by chemoprophylaxis. Studies that characterize the rate of secondary infection are needed before definitive recommendations can be made.

Between 1972 and 1989, the incidence of viridans streptococcal bacteremia at the University of Texas M. D. Anderson Cancer Center in Houston increased from one case per 10,000 admissions to 47 cases per 10,000 admissions (P less than .0001). A shock syndrome characterized by hypotension, rash, palmar desquamation, adult respiratory distress syndrome, and occasionally death developed in 26% of cases of streptococcal septicemia but in only 4% of cases of septicemia involving other gram-positive bacteria (P = .0005). The risk of streptococcal infection increased with the prophylactic administration of trimethoprim-sulfamethoxazole or a fluoroquinolone (P less than .0001) and with profound neutropenia (P less than .0001). Treatment of chemotherapy-induced gastritis with antacids or with histamine type 2 (H2) antagonists was associated with a sevenfold increase in risk (P less than .001), while sucralfate therapy did not increase risk (P = .65). Streptococcal infection may result from gastric overgrowth of organisms resistant to trimethoprim-sulfamethoxazole in an antacid- or H2 antagonist-induced alkaline environment, with the gastrointestinal tract ulceration caused by antineoplastic therapy providing a convenient portal of entry. In patients receiving chemotherapy, replacement of antacids or H2 antagonists by an acid-sparing regimen should be considered to preserve the natural acidic barrier to infection.
