Nakonieczna A, Abramowicz K, Kwiatek M, Kowalczyk E. Lysins as a powerful alternative to combat Bacillus anthracis. Appl Microbiol Biotechnol 2024; 108:366. [PMID: 38850320 PMCID: PMC11162388 DOI: 10.1007/s00253-024-13194-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Revised: 05/14/2024] [Accepted: 05/21/2024] [Indexed: 06/10/2024]
Abstract
This review gathers all, to the best of our current knowledge, known lysins, mainly bacteriophage-derived, that have demonstrated activity against Bacillus anthracis strains. B. anthracis is a spore-forming, toxin-producing bacteria, naturally dwelling in soil. It is best known as a potential biowarfare threat, an etiological agent of anthrax, and a severe zoonotic disease. Anthrax can be treated with antibiotics (ciprofloxacin, penicillin, doxycycline); however, their administration may take up even to 60 days, and different factors can compromise their effectiveness. Bacterial viruses, bacteriophages (phages), are natural enemies of bacteria and use their lytic enzymes, endolysins (lysins), to specifically kill bacterial cells. Harnessing the potential of lysins to combat bacterial infections holds promise for diminishing antibiotic usage and, consequently, addressing the escalating antibiotic resistance in bacteria. In this context, we list the lysins with the activity against B. anthracis, providing a summary of their lytic properties in vitro and the outcomes observed in animal models. Bacillus cereus strain ATCC 4342/RSVF1, a surrogate for B. anthracis, was also included as a target bacteria. KEY POINTS: • More than a dozen different B. anthracis lysins have been identified and studied. • They fall into three blocks regarding their amino acid sequence similarity and most of them are amidases. • Lysins could be used in treating B. anthracis infections.

Abstract
Multidrug-resistant Gram-positive bacteria, including bacteria from the genus Staphylococcus, are currently a challenge for medicine. Therefore, the development of new antimicrobials is required. Promising candidates for new antistaphylococcal drugs are phage endolysins, including endolysins from thermophilic phages against other Gram-positive bacteria. In this study, the recombinant endolysin LysAP45 from the thermophilic Aeribacillus phage AP45 was obtained and characterized. The recombinant endolysin LysAP45 was produced in Escherichia coli M15 cells. It was shown that LysAP45 is able to hydrolyze staphylococcal peptidoglycans from five species and eleven strains. Thermostability tests showed that LysAP45 retained its hydrolytic activity after incubation at 80 °C for at least 30 min. The enzymatically active domain of the recombinant endolysin LysAP45 completely disrupted biofilms formed by multidrug-resistant S. aureus, S. haemolyticus, and S. epidermidis. The results suggested that LysAP45 is a novel thermostable antimicrobial agent capable of destroying biofilms formed by various species of multidrug-resistant Staphylococcus. An unusual putative cell-binding domain was found at the C-terminus of LysAP45. No domains with similar sequences were found among the described endolysins.

Abstract
Bacteriophages are widely recognized as alternatives to traditional antibiotics commonly used in the treatment of bacterial infection diseases and in the food industry, as phages offer a potential solution in combating multidrug-resistant bacterial pathogens. In this study, we describe a novel bacteriophage, Kirovirus kirovense Kirov, which infects members of the Bacillus cereus group. Kirovirus kirovense Kirov is a broad-host-range phage belonging to the Caudoviricetes class. Its chromosome is a linear 165,667 bp double-stranded DNA molecule that contains two short, direct terminal repeats, each 284 bp long. According to bioinformatics predictions, the genomic DNA contains 275 protein-coding genes and 5 tRNA genes. A comparative genomic analysis suggests that Kirovirus kirovense Kirov is a novel species within the Kirovirus genus, belonging to the Andregratiavirinae subfamily. Kirovirus kirovense Kirov demonstrates the ability to preserve and decontaminate B. cereus from cow milk when present in milk at a concentration of 104 PFU/mL. After 4 h of incubation with the phage, the bacterial titer drops from 105 to less than 102 CFU/mL.

Abstract
Bacteriophage endolysins are a biologically active substances that play a specific role in the release of phage progeny by degrading the peptidoglycan of the host bacterium. In the light of antibiotic resistance, endolysins are considered as alternative therapeutic agents because of their exceptional ability to target bacterial cells.
Aim summarization of the data on the biology, structure, mechanisms of action of bacteriophage endolysins, as well as on preparations based on them, which are at different stages of research.
The results of studies of bacterial endolysins over the past 20 years were searched using the Internet resources PubMed, Web of Science, Scopus in English for the keywords: lysin, bacteriophages, holin, antibiotic resistance.
The analysis of literature data showed that the structure of phage endolysins of Gram-positive and Gram-negative bacteria differs from each other and reflects differences in their architecture due to variation in the cell wall composition of these two major bacterial groups. Depending on the cleavable bond in peptidoglycan, endolysins can be divided into at least five different groups: glycosidases (two groups aminidases and muramidases), endopeptidases, specific amidogyrolases, and lytic transglycosylases. To date, endolysins effective against a number of pathogens have been studied, including Streptococcus pneumoniae, Streptococcus pyogenes, Streptococcus agalactiae, Staphylococcus aureus, Mycobacterium spp., Pseudomonas aeruginosa, etc. A number of studies have shown the therapeutic potential of endolysins in combating antibiotic-resistant infections.

Abstract
The major problem in the management of burn wounds is infections. Methicillin-resistant Staphylococcus aureus (MRSA) is one of the major causes of infection in burn wounds. Antibiotic-resistant bacteria around the world have become a major therapeutic challenge. Bacteriophages and their lysin are suggested as an antimicrobial alternative agent. The approach of this study was to evaluate the potential of recombinant phage lysin ointment efficacy in MRSA burn wound infection in vitro. Whole genome sequencing was performed to the three isolated bacteriophages by ABM, USA using Illumina next-generation sequencing (NGS) technology. De novo assembly and genetic analysis carried out. Expression of lysin genes was performed by cloning using Escherichia coli JM109. Lysin protein extraction and purification was performed before and after cloning using precipitation by ammonium sulfate, dialysis, and gel filtration chromatography. Dose-dependent assay and time-kill curve experiment was performed for 2 lysins showed that recombinant lysin 2 functions more than its non-recombinant lysins 2 with the same concentration of 0.5 µg/mL. Both lysins' ointment was prepared and compared with commercial ointments. 62 (78.4%) out of 79 wounds a burns swabs were detected as S. aureus and S methicillin-resistant S. aureus (MRSA) rate was determined to be 29 (46.8%) in total, while 33 isolates (53.2%) determined as methicillin-sensitive S. aureus (MSSA). According to the antibiotic susceptibility test results, all S. aureus isolates were identified as sensitive against vancomycin, ceftaroline, and linezolid. Results shows one lysogenic bacteriophage and three distinct lytic specific S. aureus bacteriophage were isolated from sewage. For each of the three samples, a single contig was possible to be obtained. Sample BP-SA2 had the best coverage, and the contig was slightly longer than the other bacteriophages. In addition, BLAST search identified Staphylococcus bacteriophage vB-SscM-1 (accession KX171212.1) as the closest match to the public database. Finally, the gene annotation was checked, and two potential lysin genes were identified. Besides the two ends, there are only 4 SNPs between the three genomes. It should be noted that the two lysin genes from the genomes have no SNPs, and are identical across the three genomes. It can be seen that the three bacteriophages (BP-SA1), (BP-SA 2), and (BP-SA3) form their own tight cluster. It can be seen that (BP-SA 2) is more closely related to Staphylococcus bacteriophage vB-SscM-1 genome and most noticeable 5' region of S5 and vB-SscM-1 are now located at 3' end of vB-Sau-Clo6. The investigation of the two lysin genes in (BP-SA 2) by whole genome sequencing showed that there is some homology with vB-SscM-1; although the first gene is annotated as hypothetical protein, the second gene is annotated as amidase. The same two lysin genes are identified in all three bacteriophage genomes by the RAST. The putative protein sequences of the discovered phage lysin was analyzed using protein search with UniProt/Swiss-Prot database, and all matches suggest that the putative protein of the discovered phage lysin is a real endolysin. The three samples of bacteriophage were harboring both (Lysin 1 and lysin 2) genes were amplified. Afterward, 2-lysin genes were cloned successfully; for the dose-dependent assay, the same incubation time of recombinant lysins and its two non-recombinant lysins with the bacteria for 30 min. It is found that the bactericidal activity of these groups increased in correlation with their concentrations. For the time-kill curve experiment, it showed that Recombinant lysin 2 functions more than its non-recombinant lysins 2 with the same concentration of 0.5 µg/mL. Both lysins' ointments have potential activity against S. aureus isolates more than mupirocin and have a similar activity with Fusidic acid through applying 10 µL from lysin 1 ointment, lysin 2 ointment, mupirocin ointment 2%, and Fusidic acid cream 2%. In vitro lytic spectrum analysis revealed that 100% (29/29) tested S. aureus were sensitive. One dose of lysin ointment resulted in a reduction of 3.3 log units in the number of bacteria (from an initial count of 2 × 105 CFU/mg) at 18 hours compared with one dose of mupirocin, PBS, or Aquaphor. Specifically, this study provides evidence that the application of lysin ointment has significant potential as an alternative strategy for MRSA infections.

Abstract
BACKGROUND Bacteriophages are widely considered to be highly abundant and genetically diverse, with their role in the evolution and virulence of many pathogens becoming increasingly clear. Less attention has been paid on phages preying on Bacillus, despite the potential for some of its members, such as Bacillus anthracis, to cause serious human disease. RESULTS We have isolated five phages infecting the causative agent of anthrax, Bacillus anthracis. Using modern phylogenetic approaches we place these five new Bacillus phages, as well as 21 similar phage genomes retrieved from publicly available databases and metagenomic datasets into the Tyrovirus group, a newly proposed group named so due to the conservation of three distinct tyrosine recombinases. Genomic analysis of these large phages (~ 160-170 kb) reveals their DNA packaging mechanism and genomic features contributing to virion morphogenesis, host cell lysis and phage DNA replication processes. Analysis of the three tyrosine recombinases suggest Tyroviruses undergo a prophage lifecycle that may involve both host integration and plasmid stages. Further we show that Tyroviruses rely on divergent invasion mechanisms, with a subset requiring host S-layer for infection. CONCLUSIONS Ultimately, we expand upon our understanding on the classification, phylogeny, and genomic organisation of a new and substantial phage group that prey on critically relevant Bacillus species. In an era characterised by a rapidly evolving landscape of phage genomics the deposition of future Tyroviruses will allow the further unravelling of the global spread and evolutionary history of these Bacillus phages.

Abstract
Over the past few decades, we have witnessed a surge around the world in the emergence of antibiotic-resistant bacteria. This global health threat arose mainly due to the overuse and misuse of antibiotics as well as a relative lack of new drug classes in development pipelines. Innovative antibacterial therapeutics and strategies are, therefore, in grave need. For the last twenty years, antimicrobial enzymes encoded by bacteriophages, viruses that can lyse and kill bacteria, have gained tremendous interest. There are two classes of these phage-derived enzymes, referred to also as enzybiotics: peptidoglycan hydrolases (lysins), which degrade the bacterial peptidoglycan layer, and polysaccharide depolymerases, which target extracellular or surface polysaccharides, i.e., bacterial capsules, slime layers, biofilm matrix, or lipopolysaccharides. Their features include distinctive modes of action, high efficiency, pathogen specificity, diversity in structure and activity, low possibility of bacterial resistance development, and no observed cross-resistance with currently used antibiotics. Additionally, and unlike antibiotics, enzybiotics can target metabolically inactive persister cells. These phage-derived enzymes have been tested in various animal models to combat both Gram-positive and Gram-negative bacteria, and in recent years peptidoglycan hydrolases have entered clinical trials. Here, we review the testing and clinical use of these enzymes.

Abstract
Antimicrobial resistance (AMR) is a global crisis for human public health which threatens the effective prevention and control of ever-increasing infectious diseases. The advent of pandrug-resistant bacteria makes most, if not all, available antibiotics invalid. Meanwhile, the pipeline of novel antibiotics development stagnates, which prompts scientists and pharmacists to develop unconventional antimicrobials. Bacteriophage-derived endolysins are cell wall hydrolases which could hydrolyze the peptidoglycan layer from within and outside of bacterial pathogens. With high specificity, rapid action, high efficiency, and low risk of resistance development, endolysins are believed to be among the best alternative therapeutic agents to treat multidrug resistant (MDR) bacteria. As of now, endolysins have been applied to diverse aspects. In this review, we comprehensively introduce the structures and activities of endolysins and summarize the latest application progress of recombinant endolysins in the fields of medical treatment, pathogen diagnosis, food safety, and agriculture.

Abstract
Presently, biopreservation through protective bacterial cultures and their antimicrobial products or using antibacterial compounds derived from plants are proposed as feasible strategies to maintain the long shelf-life of products. Another emerging category of food biopreservatives are bacteriophages or their antibacterial enzymes called "phage lysins" or "enzybiotics", which can be used directly as antibacterial agents due to their ability to act on the membranes of bacteria and destroy them. Bacteriophages are an alternative to antimicrobials in the fight against bacteria, mainly because they have a practically unique host range that gives them great specificity. In addition to their potential ability to specifically control strains of pathogenic bacteria, their use does not generate a negative environmental impact as in the case of antibiotics. Both phages and their enzymes can favor a reduction in antibiotic use, which is desirable given the alarming increase in resistance to antibiotics used not only in human medicine but also in veterinary medicine, agriculture, and in general all processes of manufacturing, preservation, and distribution of food. We present here an overview of the scientific background of phages and enzybiotics in the food industry, as well as food applications of these biopreservatives.

Abstract
Bacillus cereus is a Gram-positive rod-shaped spore-forming bacterium widespread in different environmental niches. Here, we report the complete genome sequence of Bacillus cereus VKM B-370 from the All-Russian Collection of Microorganisms, the host strain for bacteriophages vB_BtS_B83, vB_BcM_Sam46, vB_BcM_Sam112, and Izhevsk.
