Abstract
Chromosomal DNA from a salivary aggregating strain of Streptococcus sanguis 12 was partially digested with PstI and ligated into the plasmid vector pUC18 and transformed into Escherichia coli JM83. A total of 1,700 recombinant clones of E. coli were examined by a colony immunoassay with antisera raised against either S. sanguis 12 whole cells or S. sanguis 12 surface fibrils. Five clones which reacted with one or the other antiserum were shown to be unique by Western blotting (immunoblotting) and restriction endonuclease digestion. One recombinant plasmid pSA2 expressed two proteins with Mrs of 20,000 and 36,000. The 36,000-Mr protein has been designated SsaB. Both proteins were purified to homogeneity by Sephadex G-75 and ion-exchange chromatography. The proteins were present in mutanolysin digests of whole-cell lysates of S. sanguis 12 and in the non-saliva-aggregating variant 12na and the hydrophilic variant 12L. Polyclonal antiserum raised against the SsaB protein reacted strongly with the cell surfaces of S. sanguis 12 and 12na but not with that of 12L. SsaB inhibited the adhesion of S. sanguis 12na to saliva-coated hydroxyapatite, indicating that the adhesin mediates the binding to the pH-sensitive receptor.

Abstract
Dominant dystrophic epidermolysis bullosa of Cockayne-Touraine occurred in a father and his son. Clinically, the child presented evident blistering, while the father, despite of his work, where minimal skin traumata frequently occur, was rarely affected. Absent or rudimentary anchoring fibrils were seen in the normal-appearing skin of the father; this suggests that other factors may play a role in the dermolytic separation.

Abstract
Samples of hydroxyapatite (HA) beads smaller than 1 mg were coated with 10 microliter of either saliva, serum, or human crevicular fluid before being added to a suspension of Streptococcus sanguis or Bacteroides gingivalis. In some assays, preparations of a granular fraction, elastase, or cathepsin G from human leukocytes were used to coat HA or to treat saliva-coated HA (SHA) before mixing with bacteria. The number of cells adhering to the beads was then counted under a scanning electron microscope by a standardized procedure. More cells were found to adhere to SHA in this assay than in the conventional large-scale assay. Human crevicular fluid, even when diluted up to three times, completely inhibited the adherence of S. sanguis to HA. A 100% inhibition of S. sanguis adherence was also observed when HA was coated with the granular fraction of leukocytes, and a 65% inhibition observed when SHA was treated with the enzyme preparation. When used to coat HA, elastase and cathepsin G reduced the adherence of S. sanguis by 30 and 50%, respectively. The binding of S. sanguis to elastase- or cathepsin G-treated SHA was also reduced. B. gingivalis 33277 was found to adhere in high numbers to SHA. Coating HA with crevicular fluid or with the lysosomal enzyme preparation had a limited negative effect. We postulate that crevicular fluid prevents the adherence of S. sanguis by virtue of either its enzyme content or its albumin content or both.

Abstract
Cell surface fibrils could be released from Streptococcus sanguis 12 but not from strains 12na or N by freeze-thawing followed by brief homogenization. Fibrils were isolated from the homogenate by ultracentrifugation or ammonium sulfate precipitation. Electron microscopy demonstrated the presence of dense masses of aggregated fibrils in these preparations. Under nondenaturing conditions, no proteins were seen in polyacrylamide gel electrophoresis (PAGE). Sodium dodecyl sulfate (SDS)-PAGE analysis revealed a single band stained with Coomassie blue and periodic acid Schiff stain with a molecular weight in excess of 300,000. The protein has been given the name long-fibril protein (LFP). The molecule was susceptible to digestion with subtilisin, pronase, papain, and trypsin, but was unaffected by chymotrypsin or muramidases. Attempts to dissociate the protein into smaller subunits with urea, guanidine, sodium thiocyanate, and HCl were unsuccessful. Gel filtration on a column of Sephacryl S-400 in the presence of 2% SDS resulted in elution of the protein at the void volume. Antibody raised against the LFP excised from an SDS-PAGE gel reacted with long fibrils on the surface of strain 12 and with isolated fibrils by an immunogold labeling technique. Monoclonal antibody reactive with LFP in SDS-PAGE also reacted with fibrils present on the cell. Antisera raised against the fibrils inhibited adherence to saliva-coated hydroxyapatite.

Abstract
Seborrhoeic dermatitis, psoriasis and atopic dermatitis in infants were studied morphologically and autoradiographically on skin biopsies. A similar picture with an increased germinative cell population and accelerated cell turnover has been found in psoriasis and seborrhoeic dermatitis. These features may suggest a relationship between both diseases.

Abstract
Hydrophobic strains of Streptococcus mutans were compared with paired variants showing reduced hydrophobicity. Extracts of hydrophobic cells contained a number of high-molecular-weight proteins which were not present on cells with decreased hydrophobicity. The proteins were found in purified cell walls, suggesting that they are located on the bacterial surface. Trypsin treatment of whole cells destroyed the proteins and reduced the hydrophobicity. Chemical analysis did not reveal any marked differences in the proportion of cell wall constituents. The amino acid compositions and lipoteichoic acid contents of hydrophobic and hydrophilic cell walls were similar. Culture supernatants from the hydrophilic variants contained high-molecular-weight proteins similar to those extracted from the cell walls of the hydrophobic parent strains, indicating that the variants were impaired in their ability to incorporate the hydrophobicity-associated proteins into the cell wall. The dominant protein had a molecular weight of 190,000, similar to that of antigen I/II (B) of S. mutans.

Abstract
Frozen skin biopsies from 3 acute and 3 chronic lesions of atopic dermatitis were examined by means of various ortho-monoclonal antibodies (OKT3, 4] not equal to----4, OKT6, OKT8; OKIa and OKM1) in an indirect immunofluorescence technique. The results show that both T helper (T4) and T suppressor cytotoxic (T8) lymphocytes are present in the inflammatory infiltration which predominantly contained Ia mononuclear cells. Despite the absence of double staining procedure, the observations suggest that T4 cells predominate over T8 cells in the acute lesions whereas the reverse tendency is noted in the chronic lesions. T8 cells are found mainly in the superficial dermis or even in the epidermis; by contrast, T4 cells tend to be more deeply located in the dermis. The lesions are characterized by a dramatic increase in the number of Langerhans cells (OKT6, OKIa+) that are found not only in the epidermis but also in the dermis.
