The CL responses of human PMNs to mutant Xc11 defective in a major cell surface antigen, PAc, and mutant Xc16 defective in two surface glucosyltransferases (GTF-I and GTF-SI) were the same as the response to the wild-type strain, Xc.

ABSTRACT Group B streptococci (GBS) are a major cause of pneumonia, sepsis, and meningitis in newborns and infants. GBS initiate infection of the lung by colonizing mucosal surfaces of the respiratory tract; adherence of the bacteria to host cells is presumed to be the initial step in and prerequisite for successful colonization (G. S. Tamura, J. M. Kuypers, S. Smith, H. Raff, and C. E. Rubens, Infect. Immun. 62:2450-2458, 1994). We have performed a genome-wide screen to identify novel genes of GBS that mediate adherence to fibronectin. A shotgun phage display library was constructed from chro

Abstract Monoclonal antibodies (mAb) generated by immunization of mice with membranes of Streptococcus pyogenes Manfredo (M type 5) were tested for their reactivity with sodium dodecyl sulfate extracts of Streptococcus mutans GS5, Streptococcus rattus BHT (formerly S. mutans, serotype b), and S. mutans Ingbritt 175 in the Western blot. The reaction of the sodium dodecyl sulfate-extracted proteins of whole S. mutans, serotype b), and S. rattus with the mAb revealed that the shared cross-reactive antigens were near m.w. 62,000 to 67,000.

ABSTRACT The nucleocapsid (N) protein of nonsegmented negative-strand (NNS) RNA viruses, when expressed in eukaryotic cells, aggregates and forms nucleocapsid-like complexes with cellular RNAs. The phosphoprotein (P) has been shown to prevent such aggregation by forming a soluble complex with the N protein free from cellular RNAs (designated N0). The N0-P complex presumably mediates specific encapsidation of the viral genome RNA. The precise mechanism by which the P protein carries out this function remains unclear. Here, by using a series of deleted and truncated mutant forms of the P protein

ABSTRACT There are suggestions that the phylogeny of Streptococcus mutans, a member of the human indigenous biota that is transmitted mostly mother to child, might parallel the evolutionary history of its human host. The relatedness and phylogeny of plasmid-containing strains of S. mutans were examined based on chromosomal DNA fingerprints (CDF), a hypervariable region (HVR) of a 5.6-kb plasmid, the rRNA gene intergenic spacer region (IGSR), serotypes, and the genotypes of mutacin I and II. Plasmid-containing strains were studied because their genetic diversity was twice as great as that of pl

Candida albicans and Streptococcus mutans are known to synergistically interact with each other in the oral cavity. For example, glucosyltransferase B (GtfB), secreted by S. mutans, can bind to the C. albicans cell surface, promoting dual-species biofilm formation. However, the fungal factors mediating interactions with S. mutans are unknown. The C. albicans adhesins Als1, Als3, and Hwp1 are key players in C. albicans single-species biofilm formation, but their roles, if any, in interacting with S. mutans have not been assessed. Here, we investigated the roles of the C. albicans cell wall adhe

Candida albicans is known to form polymicrobial biofilms with various Streptococcus spp., including mitis and mutans group streptococci. Streptococcus gordonii (mitis group) has been shown to bind avidly to C. albicans hyphae via direct cell-to-cell interaction, while the cariogenic pathogen Streptococcus mutans (mutans group) interacts with the fungal cells via extracellular glucans. However, the biophysical properties of these cross-kingdom interactions at the single-cell level during the early stage of biofilm formation remain understudied.

ABSTRACT The oral cavity is colonized by microorganisms growing in biofilms in which interspecies interactions take place. Streptococcus mutans grows in biofilms on enamel surfaces and is considered one of the main etiological agents of human dental caries. Candida albicans is also commonly found in the human oral cavity, where it interacts with S. mutans. C. albicans is a polymorphic fungus, and the yeast-to-hypha transition is involved in virulence and biofilm formation. The aim of this study was to investigate interkingdom communication between C. albicans and S. mutans based on the product
