The incorporation of a low ionic strength solution (LISS) in the micro-elution technique used for the detection of blood group antigens in stains markedly improves the test's sensitivity. This is because LISS increases the amount of antibody taken up by the antigen in the stain which results in a greater yield of antibody recovered from the slain by elution. LISS also enhances the activity of the eluted antibody if it is introduced as a suspension medium for the red cells used to detect the antibody. The introduction of suitably diluted AB serum as diluent when testing the eluates is an additional advantage. The improvement in the sensitivity of the micro-elution technique is great enough in some instances to allow the detection of an antigen in a stain which is undetectable in the absence of LISS. Moreover some doubtful positive reactions are enhanced sufficiently for the presence of an antigen to be definitely established.

ABSTRACT Of the six putative small multidrug resistance (SMR) family proteins of Pseudomonas aeruginosa, a protein encoded by the PA4990 gene (emrE Pae) shows the highest identity to the well-characterized EmrE efflux transporter of Escherichia coli. Reverse transcription-PCR confirmed the expression of emrE Pae in the wild-type strain of P. aeruginosa. Using isogenic emrE Pae, mexAB-oprM, and/or mexB deletion mutants, the contributions of the EmrE protein and the MexAB-OprM efflux system to drug resistance in P. aeruginosa were assessed by a drug susceptibility test carried out in a low-ionic-strength medium, Difco nutrient broth. We found that EmrEPae contributed to intrinsic resistance not only to ethidium bromide and acriflavine but also to aminoglycosides. In this low-ionic-strength medium, MexAB-OprM was also shown to contribute to aminoglycoside resistance, presumably via active efflux. Aminoglycoside resistance caused by these two pumps could not be demonstrated in high-ionic-strength media, such as Luria broth or Mueller-Hinton broth. The EmrE-dependent efflux of ethidium bromide was confirmed by a continuous fluorescence assay.

The mechanism of retraction of the longitudinal flagellum of Ceratium tripos was studied by making extracted models of the flagellum. Non-detergent models extracted in low ionic strength medium containing 1 M-glucose, 10 mM-EDTA, and 50 mM-Tris X HCl buffer (pH 8.0), retracted when Ca2+, Mg2+, Ba2+, Sr2+, Mn2+ or Cd2+ was applied locally with a glass capillary. A demembranated model of the flagellum was made with an extraction medium containing 0.8-1.0 M-glucose, 20 mM-Tris-acetate (pH 7.8), 2 mM-EGTA, 5–7 mM-MgSO4, 0.1 M-potassium glutamate and 0.1% Triton X-100. The model required a concentration of Mg2+ of a few mmol/l for successful reactivation of both retraction and undulation, and about 0.1 M-potassium glutamate (or sodium glutamate) for reactivation of undulation. Neither type of motion of the models could be reactivated above 35 degrees C. Ca2+ induced the retraction at pCa 5.5 or less. In addition to Ca2+, Mn2+, Ba2+, Sr2+ and Cd2+ also induced retraction but Mg2+, La3+ or Tb3+ did not. Although ATP was required for undulation, it was not required for retraction. Co-incubation with hexokinase to remove contaminating ATP did not suppress the retraction. The potent ATPase inhibitor, orthovanadate, inhibited undulation at 10 micron but did not inhibit retraction even at 2 mM. SH blockers, N-ethylmaleimide and dithio-bis-nitrobenzoic acid strongly suppressed undulation but had no effect on retraction. Calmodulin inhibitors, trifluoperazine and chlorpromazine, also had no effect on retraction. These data indicate that undulation is generated by a 9 + 2 microtubular axoneme using energy released by hydrolysis of ATP and that retraction can be induced by Ca2+ without a requirement for ATP.
