Simultaneous recovery of beta-lactamase-negative and beta-lactamase-positive Haemophilus influenzae type b from cerebrospinal fluid of a neonate.

A case of Haemophilus influenzae type b meningitis in a neonate from whom both a beta-lactamase-negative and a beta-lactamase-positive strain were isolated simultaneously is reported. Both bacteriology laboratory technicians and clinicians should be aware of this phenomenon when performing sensitivity tests on H influenzae isolates or treating patients with serious H influenzae infection.

Quantitative nitrobluetetrazolium reduction by normal newborn monocytes.

The phagocytosis-induced metabolic burst of human newborn monocytes, as evaluated by their capacity to reduce NBT, was comparable to that of adult monocytes. The NBT reduction assay constitutes a simple method of ascertaining the functional capacity of human monocytes.

Group B streptococcal long-chain reaction.

The streptococcal long-chain reaction was adapted for the measurement of type-specific antibodies to group B beta-hemolytic streptococci (GBBHS). Rabbit antisera incubated with homologous but not heterologous GBBHS produced chains that were 18 to 33 times longer than chains produced by normal rabbit sera. The long chains were easily apparent, in most instances, by scanning the slides. Human sera with mouse protective and opsonic activity against GBBHS serotype Ia produced chains that were always significantly longer than those produced by incubation in nonimmune human sera. Absorption of rabbit or human sera with homologous but not heterologous organisms inhibited the capacity to induce the formation of long chains. The long-chain assay is a simple, rapid, and reproducible test that could constitute a valuable tool for the rapid identification of anti-GBBHS antibodies.
