Phages and Human Health: More Than Idle Hitchhikers
viruses Review Phages and Human Health: More Than Idle Hitchhikers Dylan Lawrence 1,2 , Megan T. Baldridge 1,2,* and Scott A. Handley 2,3,* 1 Division of Infectious Diseases, Department of Medicine, Washington University School of Medicine, St. Louis, MO 63110, USA 2 Edison Family Center for Genome Sciences & Systems Biology, Washington University School of Medicine, St. Louis, MO 63110, USA 3 Department of Pathology and Immunology, Washington University School of Medicine, St. Louis, MO 63110, USA * Correspondence: [email protected] (M.T.B.); [email protected] (S.A.H.) Received: 2 May 2019; Accepted: 25 June 2019; Published: 27 June 2019 Abstract: Bacteriophages, or phages, are viruses that infect bacteria and archaea. Phages have diverse morphologies and can be coded in DNA or RNA and as single or double strands with a large range of genome sizes. With the increasing use of metagenomic sequencing approaches to analyze complex samples, many studies generate massive amounts of “viral dark matter”, or sequences of viral origin unable to be classified either functionally or taxonomically. Metagenomic analysis of phages is still in its infancy, and uncovering novel phages continues to be a challenge. Work over the past two decades has begun to uncover key roles for phages in different environments, including the human gut. Recent studies in humans have identified expanded phage populations in both healthy infants and in inflammatory bowel disease patients, suggesting distinct phage activity during development and in specific disease states. In this review, we examine our current knowledge of phage biology and discuss recent efforts to improve the analysis and discovery of novel phages. -
Therapeutic Efficacy of Bacteriophages Ramasamy Palaniappan and Govindan Dayanithi
Chapter Therapeutic Efficacy of Bacteriophages Ramasamy Palaniappan and Govindan Dayanithi Abstract Bacteriophages are bacterial cell-borne viruses that act as natural bacteria killers and they have been identified as therapeutic antibacterial agents. Bacteriophage therapy is a bacterial disease medication that is given to humans after a diagnosis of the disease to prevent and manage a number of bacterial infections. The ability of phage to invade and destroy their target bacterial host cells determines the efficacy of bacteriophage therapy. Bacteriophage therapy, which can be specific or nonspecific and can include a single phage or a cocktail of phages, is a safe treat- ment choice for antibiotic-resistant and recurrent bacterial infections after antibi- otics have failed. A therapy is a cure for health problems, which is administered after the diagnosis of the diseases in the patient. Such non-antibiotic treatment approaches for drug-resistant bacteria are thought to be a promising new alterna- tive to antibiotic therapy and vaccination. The occurrence, biology, morphology, infectivity, lysogenic and lytic behaviours, efficacy, and mechanisms of bacterio- phages’ therapeutic potentials for control and treatment of multidrug-resistant/ sensitive bacterial infections are discussed. Isolation, long-term storage and recov- ery of lytic bacteriophages, bioassays, in vivo and in vitro experiments, and bacteri- ophage therapy validation are all identified. Holins, endolysins, ectolysins, and bacteriocins are bacteriophage antibacterial enzymes that are specific. Endolysins cause the target bacterium to lyse instantly, and hence their therapeutic potential has been explored in “Endolysin therapy.” Endolysins have a high degree of bio- chemical variability, with certain lysins having a wider bactericidal function than antibiotics, while their bactericidal activities are far narrower. -

UC Davis Norma J. Lang Prize for Undergraduate Information Research Title The Secret Life of Bacteriophages: How Did They Originate? Permalink https://escholarship.org/uc/item/0mv3j0wg Author Hand, Katherine Publication Date 2021-05-28 eScholarship.org Powered by the California Digital Library University of California Hand 1 Katherine Hand March 12, 2021 Dr. Bradley Sekedat UWP 101 The Secret Life of Bacteriophages: How Did They Originate? One of life’s greatest mysteries, the origin of viruses, remains unsolved. To crack the case, scientists proposed three major hypotheses. How the origins of viruses continue to remain undiscovered despite the hypotheses put forward calls for further investigation into the topic. Discovered in the early twentieth century by Frederick Twort and Felix d’Herelle ( Drulis-Kawa et al., 2015 ), bacteriophages are considered the most successful entities (Moelling, 2012) and they help build the genomes of all species. What began as a narrow belief that viruses only prefer to genetically exchange with hosts of their superkingdom (Archaea, Bacteria, or Eukarya), studies on bacteriophages prove this untrue. The secret life of bacteriophages is seemingly more peculiar in the human gut as they coevolve with bacteria and interact with our immune system. Their distinctive interactions with white blood cells (WBC) and their hosts demonstrate a connection with their protein fold and structural make-up. This leaves us with an interesting question: where did the phages originate from? Assessing how bacteriophages can be antimorphic mutations 1 of early bacterial defense mechanisms where an accumulation of proteins that should not have bound together, bound together over time and self-infected a bacterial cell from within might be our answer. -
Isolation of Bacteriophages Obtained from Limestones Cave Soils And
ISOLATION OF BACTERIOPHAGES FROM LIMESTONE CAVE SOILS AND EVALUATION OF THEIR POTENTIAL APPLICATION AS BIOCONTROL AGENTS OF PSEUDOMONAS AERUGINOSA By HASINA MOHAMMED MKWATA A thesis presented in fulfillment of the requirements for the degree of Master of Science (Research) School of Chemical Engineering and Science, Faculty of Engineering, Computing and Science SWINBURNE UNIVERSITY OF TECHNOLOGY 2018 ABSTRACT The emergence and frequent occurrence of multidrug-resistant and extremely drug- resistant bacteria have raised a major concern because infections caused by these bacteria are often associated with high mortality rates, prolonged hospitalization, and high treatment costs. This situation is predicted to worsen in the future due to a massive decline in the development of new antibiotics in recent years. Bacteriophages and their derivatives have long been exploited as powerful and promising alternative antibacterial agents in phage therapy and biocontrol applications. Limestone caves remain relatively unexplored as a source of novel lytic bacteriophages compared with other environments, despite being one of the most propitious sources for the discovery of novel antimicrobial compounds. This research presents, for the first time, the screening and isolation of lytic bacteriophages targeting different pathogenic bacteria from limestone caves of Sarawak, and evaluation of their potential application as biological disinfectants to control P. aeruginosa infections. A total of 33 lytic bacteriophages were isolated from samples obtained from FCNR and WCNR targeting bacterial strains Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella pneumoniae, Streptococcus pneumoniae, Escherichia coli and Vibrio parahaemolyticus, using enrichment culture method. Phage amplification was performed, and lysates were obtained, and spot tested on lawns of various bacteria strains to assess their lysis spectrum. -

Scientific Review From Bacteriophage to Antibiotics and Back Jasminka Talapko1, Ivana Škrlec2, Tamara Alebić3, Sanja Bekić3, Aleksandar Včev1,3 1Faculty of Dental Medicine and Health, J. J. Strossmayer University, Osijek, Croatia 2Department of Biology, Faculty of Dental Medicine and Health, J. J. Strossmayer University, Osijek, Croatia 3Faculty of Medicine, Josip Juraj Strossmayer University of Osijek, Osijek, Croatia ABSTRACT Life is a phenomenon, and evolution has given it countless forms and possibilities of survival and formation. Today, almost all relationship mechanisms between humans who are at the top of the evolutionary ladder, and microorganisms which are at its bottom are known. Preserving health or life is not just an instinctive response to threat anymore; rather it is a deliberate action and use of knowledge. During major epidemics and wars which create great suffering, experi- ences of the man-disease (cause) relationships were examined, so we can note the use of bacteriophages in Poland and Russia before and during the Second World War, while almost at the same time antibiotic therapy was introduced. Since bacteriophages “tracked” the evolution of bacteria, the mechanism of their action lies in the prokaryotic cell, and it is not dangerous for the eukaryotic cell of human parenchyma. It is, therefore, necessary only to reuse these experiences nowadays when we are convinced that bacteria have an inexhaustible genetic and phenotypic resistance mechanism of their own. Antibiotics continue to represent the foundation of health preservation, but now they work together with specific viruses – bacteriophages that we can produce and apply in the context of multi-resistance, as well as for the preparation of new pharmacological preparations. -
Volume 5, Number 2 · Spring 2010
VOLUME 5, NUMBER 2 · SPRING 2010 DISTINCTIONS Journal of the Kingsborough Community College Honors Program Volume 5, Number 2 Spring 2010 Kingsborough Community College The City University of New York EDITOR’S COLUMN Une raison d’être his semester, I have felt energized by the buzzing student enthusiasm about social issues and the T interlocking geopolitical relationships that give such issues all their nefarious subtleties. I‘m talking here about food politics, human trafficking, the U.S. role in globalization, and a host of other challenges. I have been much impressed, particularly within the Honors program, but also in other corners of the College and University, how many student-driven initiatives are going on. This Spring-2010 issue of Distinctions reflects these collective concerns, as well as more personal attempts at exploration – some political, some not. These pieces explore various aspects of our present condition through multiple means, from Micaela Santana‘s photographic meditation on air travel to Dorothy Franco‘s discussion of operatic technique, from Cheryl Bond‘s queries about Afghan art history to Julianne Miller‘s interrogation of Fannie Mae. (I know, we need to get more men to do such good work!) In reading these essays, as well as the other 40 or so submissions, I remember that being able to write such pieces requires both a commitment to taking the time to read, observe, and reflect, as well as the luxury of doing so. And I use the term ―luxury‖ because, for many students at Kingsborough, such intellectual work is not necessarily a given. I routinely hear stories of domestic violence, economic hardship, medical problems, and emotional trauma from my students. -
Phage Therapy in Veterinary Medicine
antibiotics Review Phage Therapy in Veterinary Medicine Rosa Loponte, Ugo Pagnini, Giuseppe Iovane and Giuseppe Pisanelli * Department of Veterinary Medicine and Animal Production, University of Naples Federico II, via Federico Delpino, 1, 80137 Naples, Italy; [email protected] (R.L.); [email protected] (U.P.); [email protected] (G.I.) * Correspondence: [email protected]; Tel.: +39-081-2536363 Abstract: To overcome the obstacle of antimicrobial resistance, researchers are investigating the use of phage therapy as an alternative and/or supplementation to antibiotics to treat and prevent infections both in humans and in animals. In the first part of this review, we describe the unique biological characteristics of bacteriophages and the crucial aspects influencing the success of phage therapy. However, despite their efficacy and safety, there is still no specific legislation that regulates their use. In the second part of this review, we describe the comprehensive research done in the past and recent years to address the use of phage therapy for the treatment and prevention of bacterial disease affecting domestic animals as an alternative to antibiotic treatments. While in farm animals, phage therapy efficacy perspectives have been widely studied in vitro and in vivo, especially for zoonoses and diseases linked to economic losses (such as mastitis), in pets, studies are still few and rather recent.

We are happy to welcome you to Wrocław for the 5th meeting of the Viruses of Microbes series. This series was launched in the year 2010 in Paris, and was continued in Brussels (2012), Zurich (2014), and Liverpool (2016). This year our meeting is co-organized by two partner institutions: the University of Wrocław and the Hirszfeld Institute of Immunology and Experimental Therapy, Polish Academy of Sciences. The conference venue (University of Wrocław, Uniwersytecka 7-10, Building D) is located in the heart of Wrocław, within the old, historic part of the city. This creates an opportunity to experience the over 1000-year history of the city, combined with its current positive energy. The Viruses of Microbes community is constantly growing. More and more researchers are joining it, and they represent more and more countries worldwide. Our goal for this meeting was to create a true global platform for networking and exchanging ideas. We are most happy to welcome representatives of so many countries and continents. To accommodate the diversity and expertise of the scientists and practitioners gathered by VoM2018, the leading theme of this conference is “Biodiversity and Future Application”. With the help of your contribution, this theme was developed into a program covering a wide range of topics with the strongest practical aspect. -
Bacteriophages As Potential Tools for Use in Antimicrobial Therapy and Vaccine Development
pharmaceuticals Review Bacteriophages as Potential Tools for Use in Antimicrobial Therapy and Vaccine Development Beata Zalewska-Pi ˛atek 1,* and Rafał Pi ˛atek 1,2 1 Department of Molecular Biotechnology and Microbiology, Chemical Faculty, Gda´nskUniversity of Technology, Narutowicza 11/12, 80-233 Gda´nsk,Poland; [email protected] 2 BioTechMed Center, Gda´nskUniversity of Technology, Narutowicza 11/12, 80-233 Gda´nsk,Poland * Correspondence: [email protected]; Tel.: +58-347-1862; Fax: +58-347-1822 Abstract: The constantly growing number of people suffering from bacterial, viral, or fungal infec- tions, parasitic diseases, and cancers prompts the search for innovative methods of disease prevention and treatment, especially based on vaccines and targeted therapy. An additional problem is the global threat to humanity resulting from the increasing resistance of bacteria to commonly used antibiotics. Conventional vaccines based on bacteria or viruses are common and are generally effective in pre- venting and controlling various infectious diseases in humans. However, there are problems with the stability of these vaccines, their transport, targeted delivery, safe use, and side effects. In this context, experimental phage therapy based on viruses replicating in bacterial cells currently offers a chance for a breakthrough in the treatment of bacterial infections. Phages are not infectious and pathogenic to eukaryotic cells and do not cause diseases in human body. Furthermore, bacterial viruses are sufficient immuno-stimulators with potential adjuvant abilities, easy to transport, and store. They can also be produced on a large scale with cost reduction. In recent years, they have also provided an ideal platform for the design and production of phage-based vaccines to induce protective host immune responses.
