Dear Participants, On behalf of the BBM2017 Organizing Committee, we thank you for attending the 23rd Boston Bacterial Meeting! Over the past 23 years, the BBM has offered an intellectually stimulating and collegial atmosphere for bacteriologists throughout the New England area to discuss cutting-edge scientific research and to share ideas. The BBM is also proud to provide a forum that fosters collaborations between researchers from all levels, within both academia and industry. The BBM has grown significantly since its inception. The past few years have seen record-breaking participation from researchers both near and far. Given last year’s success and by popular demand we have brought back the interactive break out sessions lead by leaders in several fields within microbiology. This year we are also excited about the launching of our new website www.bostonbacterial.org. Although the BBM has undergone many changes over the last 23 years, one crucial element has remained consistent: our commitment to the highest quality research. This is particularly evident in the 24 talks and over 120 posters that will be presented at this year’s meeting. This year we are excited to feature Dr. Susan Gottesman as our Keynote Speaker. Dr. Gottesman is an NIH Distinguished Investigator, Head of the Biochemical Genetics Section at the National Cancer Institute, which is part of the National Institutes of Health (NIH). Dr. Gottesman has pioneered studies on post-transcriptional mechanisms of regulation in bacterial systems, with a focus on the role of energy-dependent proteolysis in regulation and the role of small non-coding RNAs in regulating translation and mRNA stability. Dr. Gottesman is a member of the National Academy of Sciences and the American Academy of Arts and Sciences. She received the Abbott-ASM Lifetime Achievement Award in 2011. The BBM would not be possible without the efforts of the Organizing Committee, a highly motivated and enthusiastic group of graduate students and postdocs dedicated to the success of this meeting. We are also indebted to our faculty sponsors, Tom Bernhardt and Ethan Garner, and meeting founders, Rich Losick, Roberto Kolter, John Mekalanos, and Andrew Wright, and thank them for their continuing guidance. Additionally, we thank our generous industry and NIH sponsors for their financial support! Finally, we thank all of you for your participation and support of the BBM. We hope you will find the next two days both intellectually and socially fulfilling. Thank you for joining us! Patty Rohs and Florencia Caro Co-chairs, BBM2017 3 2017 Boston Bacterial Meeting - Schedule and Introduction KEYNOTE SPEAKER SUSAN GOTTESMAN, PH.D. Susan Gottesman is an NIH Distinguished Investigator in the Biochemical Genetics Section at the National Cancer Institute (NCI), which is part of the National Institutes of Health (NIH). Dr. Gottesman has pioneered studies on post- transcriptional mechanisms of regulation in bacterial systems, with a focus on the role of energy-dependent proteolysis in regulation and the role of small non-coding RNAs in regulating translation and mRNA stability. One focus of her work has been on how these regulatory inputs affect the bacteria’s response to stress. Her laboratory has been interested in novel mechanisms for gene regulation and how these mechanisms contribute to global control circuits in Escherichia coli (E. coli). For many years, the focus of the laboratory was energy-dependent proteolysis. In the past decade, much of the lab has shifted to studying small regulatory RNAs, although they continue to investigate the mechanisms for regulating energy-dependent proteolysis. Her group first encountered small RNAs when studying the regulation of synthesis of a substrate for energy-dependent proteases. They continue to see significant overlap between mRNAs regulated by small RNAs and the products of these mRNAs that are regulated by proteolysis. Dr. Gottesman received her Ph.D. from the Department of Microbiology at Harvard University and became a postdoctoral fellow at the NIH. She then went to the Massachusetts Institute of Technology (MIT) as a research associate and returned to the NIH in 1976 as a senior investigator in the Laboratory of Molecular Biology, where she has remained. She was elected to the National Academy of Sciences in 1998 and the American Academy of Arts and Sciences in 1999. She received the Abbott-ASM Lifetime Achievement Award in 2011.

KGaA, 69469 Weinheim, Germany, 2013. 1 Table of Contents Excerpt Mucin coatings suppress surface attachment by the bacteria Streptococcus pneumoniae and Staphylococcus aureus. Bacterial repulsion by mucin coatings is dependent on the presence of mucin-bound glycans. Upon mucin deglycosylation, the coatings display measurable changes in coating thickness and softness, as well as antifouling capacity. This study highlights the structural and functional role of glycans in mucin coatings. J. Y. Co†, T. Crouzier†, and K. Ribbeck* Probing the Role of Mucin-Bound Glycans in Bacterial Repulsion by Mucin Coatings Abstract Microbial colonization of implanted medical devices in humans can lead to device failure and life-threatening infections. One strategy to prevent this unwanted colonization is to coat devices with polymers that reduce bacterial attachment. This study investigates how mucins, a class of biopolymers found in mucus, can be used as surface coatings to prevent attachment of selected respiratory pathogens to polystyrene surfaces.

  • Mucins Trigger Dispersal of Pseudomonas Aeruginosa Biofilms
    www.nature.com/npjbiofilms ARTICLE OPEN Mucins trigger dispersal of Pseudomonas aeruginosa biofilms Julia Y. Co1,2, Gerardo Cárcamo-Oyarce3, Nicole Billings1, Kelsey M. Wheeler1,2, Scott C. Grindy4, Niels Holten-Andersen4 and Katharina Ribbeck1 Mucus is a biological gel that lines all wet epithelia in the body, including the mouth, lungs, and digestive tract, and has evolved to protect the body from pathogenic infection. However, microbial pathogenesis is often studied in mucus-free environments that lack the geometric constraints and microbial interactions in physiological three-dimensional mucus gels. We developed fluid-flow and static test systems based on purified mucin polymers, the major gel-forming constituents of the mucus barrier, to understand how the mucus barrier influences bacterial virulence, particularly the integrity of Pseudomonas aeruginosa biofilms, which can become resistant to immune clearance and antimicrobial agents. We found that mucins separate the cells in P. aeruginosa biofilms and disperse them into suspension. Other viscous polymer solutions did not match the biofilm disruption caused by mucins, suggesting that mucin-specific properties mediate the phenomenon. Cellular dispersion depended on functional flagella, indicating a role for swimming motility. Taken together, our observations support a model in which host mucins are key players in the regulation of microbial virulence. These mucins should be considered in studies of mucosal pathogenesis and during the development of novel strategies to treat biofilms. npj Biofilms

Here, we demonstrate that mucin glycoproteins, the gel-forming constituents of native mucus, are suitable for assembly into robust hydrogels capable of facilitating the sustained release of hydrophobic and hydrophilic drugs. Covalently-crosslinked mucin hydrogels were generated via exposure of methacrylated mucin to ultraviolet light in the presence of a free radical photoinitiator. The hydrogels exhibited an elastic modulus similar to that of soft mammalian tissue and were sensitive to proteolytic degradation by pronase. Paclitaxel, a hydrophobic anti-cancer drug, and polymyxin B, a positively-charged hydrophilic antibacterial drug, were retained in the hydrogels and released linearly with time over seven days. After four weeks of drug release, the hydrogels continued to release sufficient amounts of active paclitaxel to reduce HeLa cell viability and sufficient amounts of active polymyxin B to prevent bacterial proliferation. Along with previously-established anti-inflammatory, anti-viral, and hydrocarbon- solubilizing properties of mucin, the results of this study establish mucin as a readily-available, chemically-versatile, naturally-biocompatible alternative to complex multifunctional synthetic polymers as building blocks in the design of biomaterials for sustained drug delivery.

Mucus can bind small molecules and influence bacterial physiology, two factors that may affect the efficacy of antibiotics. In spite of this, the impact of mucus on antibiotic activity has not been thoroughly characterized. We examined the activity of polymyxin and fluoroquinolone antibiotics against the opportunistic pathogen Pseudomonas aeruginosa in native mucus and purified mucin biopolymer environments. We found that mucus reduces the effectiveness of polymyxins and fluoroquinolones against P. aeruginosa. Mucin biopolymers MUC5AC, MUC2, and MUC5B are primary contributors to this reduction. Our findings highlight that the biomaterial environmental context should be considered when evaluating antibiotics in vitro.

Mucins, the primary structural components of mucus that creates its viscoelastic properties, are critical components of the gel layer that protect against invading pathogens. Altered mucin production has been implicated in diseases such as ulcerative colitis, asthma, and cystic fibrosis, which highlights the importance of mucins in maintaining homeostasis. Different types of mucins exist throughout the body in various locations such as the gastrointestinal tract, lungs, and female genital tract, but this review will focus on mucins in the oral cavity. Salivary mucin structure, localization within the oral cavity, and defense mechanisms will be discussed. These concepts will then be applied to present what is known about the protective function of mucins in oral diseases such as HIV/AIDS, oral candidiasis, and dental caries.
