Occurrence of antibodies to teichoic acid in patients with diseases other than staphylococcal infection.

To determine the usefulness of the teichoic acid antibody (TAA) test in conditions where unspecific viral and bacterial antibodies are often encountered, we measured TAA by the gel-diffusion method in 475 patients without known staphylococcal disease; they included 213 patients with arthritis, 108 with liver diseases, 100 with gastro-intestinal disorders and 54 with acute pharyngitis. Positive controls were 104 patients with Staphylococcus aureus bacteraemia and 203 healthy adults were negative controls. Thirteen (6%) of the healthy adults had positive TAA titres (greater than or equal to 4), and the highest titre was 8 in two people (1%). Positive titres were found in 38% of patients with S. aureus bacteraemia and high titres (greater than or equal to 8) were seen in 24%. Among the patients with arthritis, positive TAA titres were found significantly more often than in healthy controls in patients with Yersinia arthritis (p less than 0.01) and systemic lupus erythematosus (SLE; p less than 0.02). In other patient groups, the percentage of positive TAA titres did not differ significantly from that in healthy adults. Eight (2%) of the 475 patients without known staphylococcal infection had TAA titres greater than or equal to 8 but these high titres were not associated with any particular disease group. Only two of these eight patients had slightly raised antibody to staphylococcal alpha-haemolysin. We conclude that the TAA test cannot be used as a reliable indicator of septic staphylococcal disease in patients with Yersinia arthritis or SLE, but that in general, TAA titres greater than or equal to 8 point strongly to S. aureus infection even in patients with autoimmune or liver diseases.

[Therapeutic action of proteolytic enzymes and antibiotics in experimental staphylococcal infection. The effect of lincomycin, chymotrypsin and their combinations on the level of autoplaque-forming cells in the blood and the immune adherence reaction of staphylococci].

The effect of lincomycin, chymotrypsin and their combination on the blood count of the plaque-autoforming cells (PAFC) and immune adhesion (IA) of staphylococci was studied on mice with staphylococcal infection. The infected mice were divided into 4 groups: nontreated, lincomycin treated, chymotrypsin treated, and lincomycin + chymotrypsin treated. The doses of lincomycin and chymotrypsin were 150 and 2 mg/kg, respectively. The mice were decapitated by the 3rd, 7th, 14th or 21st day of the infection and treatment and the blood was collected for the count of the PAFC and IA. A decrease in the rate of IA with a simultaneous increase in the PAFC count was found in the untreated mice and the mice treated with lincomycin alone. The use of chymotrypsin and its combination with lincomycin stimulated IA and lowered the level of autosensibilization.

Risk of developing toxic shock syndrome associated with toxic shock syndrome toxin 1 following nongenital staphylococcal infection.

Few risk factors for nonmenstrual toxic shock syndrome (TSS) have been identified. This study sought to determine at what rate and under what circumstances nongenital toxigenic Staphylococcus aureus infections led to TSS. Clinical isolates of S. aureus were examined for the production of TSS toxin 1 (TSST-1), and available sera from infected patients were tested for antibody to this toxin. Twenty-six percent of 810 isolates produced TSST-1. Isolates from children were more likely to be positive for TSST-1 than were those from adults. None of 57 patients with TSST-1-positive staphylococcal infection and a TSST-1 antibody titer of greater than or equal to 1:100 developed TSS. Eight of 65 tested patients with TSST-1-positive isolates had antibody below the presumably protective level of 1:100. Two of these patients had definite TSS, three had probable or possible TSS, and three probably did not have TSS. In patients lacking protective antibody to TSST-1, the interval between acquisition and infection with staphylococci, the type and amount of toxins produced, the site of infection, and still-unclarified aspects of host susceptibility may all affect the rate and severity of TSS.

Staphylococcal infections among newborn babies in two towns in north Norway.

1137 newborn infants in the towns of Harstad and Tromsø were examined for Staphylococcus aureus. The children were followed for two months after birth, and 10% showed signs of infection. The first symptom occurred on the average on the ninth day of life, while the average stay in the maternity ward was six days. 85% of those being regarded on clinical grounds as infected with S aureus showed growth of this bacterium on cultivation of the specimens taken. Over 80% of the strains were resistant to penicillin G/V and approximately 11% resistant to fucidic acid. Resistance to other antibiotics was not found to present any problem. A survey of staphylococcal infections among the newborn should include both the stay in the maternity ward and the first week at home.
