A team led by scientists from CEITEC Masaryk University has uncovered the infection mechanism of tailed bacteriophages – a group of viruses that infect bacteria. These phages target, among others, Staphylococcus aureus, a major cause of bacterial infections that is often resistant to antibiotics. The bacterium belongs to a group of Gram-positive bacteria characterised by an exceptionally thick cell wall. Although the infection mechanisms of some other bacteriophages have been described previously, the way tailed phages infecting Staphylococcus aureus and other thick-walled bacteria invade their hosts had remained unknown. The researchers have now revealed how such a bacteriophage breaches the protective barrier of the bacterial cell and delivers its genetic material inside. Their findings could contribute to the development of new strategies for combating antibiotic-resistant bacteria.Staphylococcus aureus is one of the most common sources of bacterial infections in humans. It can cause skin infections, pneumonia, and even life-threatening bloodstream infections. Moreover, many of its strains have become resistant to commonly used antibiotics, increasing interest in alternative treatment approaches such as bacteriophage therapy.“Bacteriophages are the most abundant biological entities on Earth and have been infecting bacteria for billions of years. Yet we still do not fully understand how they overcome the cell wall of certain Gram-positive bacteria. By reconstructing the bacteriophage structure before and after it attaches to a bacterial cell, we were able to reveal this process,” says <a target="_blank" rel="noopener noreferrer" href="https://www.ceitec.eu/jan-binovsky-ph-d/u91173?page=publication">Ján Bíňovský</a> of CEITEC Masaryk University, who led the study together with Marta Šiborová.Bacteriophage 812, investigated in this study, specifically infects Staphylococcus aureus. The researchers discovered that once it recognises the correct host, the protein structure at the tip of its tail undergoes extensive rearrangements. Individual components of this structure, which resembles a lunar landing module, reorganise into a new configuration that enables the virus to firmly attach to the bacterial surface. At the same time, a mechanism is activated that triggers contraction of the phage tail.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_Jak_zabit_zlateho_stafylokoka_novy_pohled_na_viry_ktere_si_poradi_s_bakteriemi_01c86d5e42.jpg" alt="CEITEC/Plevka Lab: How to Kill Staphylococcus Aureus: A New Insight into Viruses That Can Defeat Bacteria: Phage before attachment to the bacterial cell." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CEITEC_Jak_zabit_zlateho_stafylokoka_novy_pohled_na_viry_ktere_si_poradi_s_bakteriemi_01c86d5e42.jpg 245w," sizes="100vw" width="4339" height="1600"><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_Jak_zabit_zlateho_stafylokoka_novy_pohled_na_viry_ktere_si_poradi_s_bakteriemi_2_53422574db.jpg" alt="CEITEC/Plevka Lab: How to Kill Staphylococcus Aureus: A New Insight into Viruses That Can Defeat Bacteria: Phage attached to the bacterial cell." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CEITEC_Jak_zabit_zlateho_stafylokoka_novy_pohled_na_viry_ktere_si_poradi_s_bakteriemi_2_53422574db.jpg 245w," sizes="100vw" width="4085" height="1600">“The process resembles the release of an extended spring. The bacteriophage tail contracts to approximately half of its original length, and the released energy drives the central tube through the bacterium's protective layers. The virus can then deliver its genetic material into the cell and initiate infection,” explains Marta Šiborová.Unlike many other bacteria, Staphylococcus aureus possesses an exceptionally thick cell wall. The researchers therefore investigated in detail how the bacteriophage overcomes this barrier. They found that the virus employs a combination of mechanical force and enzymatic activity. Some components of its infection apparatus likely disrupt teichoic acids, which form the outer protective layer of the bacterial cell wall. Other proteins then degrade peptidoglycan, the main structural component of the cell wall. Finally, the bacteriophage penetrates the inner lipid membrane, allowing its central tube to enter the bacterial cell.The findings show that the bacteriophage does not function as a simple "needle", but rather as a sophisticated nanomachine composed of dozens of cooperating proteins.Although this is fundamental research, the findings may prove important for future medical applications. Bacteriophages are considered one of the promising alternatives for treating infections caused by antibiotic-resistant bacteria.“If we want to use bacteriophages therapeutically in the future – or even engineer them for specific medical applications – we first need to understand in detail how they work. Our study provides fundamental insight into how bacteriophages recognise their hosts and initiate infection,” says <a target="_blank" rel="noopener noreferrer" href="https://www.ceitec.eu/pavel-plevka-ph-d/u26854">Pavel Plevka</a>, structural biologist and head of a research group at CEITEC Masaryk University.<blockquote>The study, published in <a target="_blank" rel="noopener noreferrer" href="https://link.springer.com/article/10.1038/s44318-026-00834-9">EMBO Journal</a>, also involved researchers from the Faculty of Science, Masaryk University.</blockquote><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_Jak_zabit_zlateho_stafylokoka_novy_pohled_na_viry_ktere_si_poradi_s_bakteriemi_3_fba5a65145.jpg" alt="CEITEC/Plevka Lab: How to Kill Staphylococcus Aureus: A New Insight into Viruses That Can Defeat Bacteria: Black = protein structure at the tip of the tail after the conformational change; red = portion of the tail that has begun to contract; blue = portion of the tail that remains extended." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CEITEC_Jak_zabit_zlateho_stafylokoka_novy_pohled_na_viry_ktere_si_poradi_s_bakteriemi_3_fba5a65145.jpg 245w," sizes="100vw" width="1600" height="782"><blockquote><h4>The original article</h4><h4><a target="_blank" rel="noopener noreferrer" href="https://link.springer.com/article/10.1038/s44318-026-00834-9">Conformational changes of the baseplate regulating tail contraction of Staphylococcus phage 812</a></h4>Ján Bíňovský, Marta Šiborová, Maryna Zlatohurska, Jiří Nováček, Pavol Bárdy, Roman Baška, Karel Škubník, Tibor Botka, Martin Benešík, Roman Pantuček, Konstantinos Tripsianes &amp; Pavel PlevkaEMBO J (2026)<a target="_blank" rel="noopener noreferrer" href="https://doi.org/10.1038/s44318-026-00834-9">https://doi.org/10.1038/s44318-026-00834-9</a>&nbsp;<h6>licensed under <a target="_blank" rel="noopener noreferrer" href="https://creativecommons.org/licenses/by/4.0/">CC-BY 4.0</a></h6></blockquote>

height="386"><h4>Sample preparation, improved</h4>Improving various aspects of chromatography and mass spectrometry analyses often starts with sample preparation. &nbsp;Solid-phase extraction (SPE) or "liquid-solid phase extraction" is a sample preparation technology that uses particles of chromatographic packing material, usually in a cartridge or 96-well plate format, to chemically separate different analytes and aid in removing matrix components in a sample. &nbsp;SPE is a proven sample preparation tool for simple sample matrix removal, including common interferences like proteins, salts, fats and phospholipids. This matrix removal provides many benefits, including matrix effect reduction and an increase in sample concentration and analyte specificity. Matrix removal also significantly simplifies chromatographic complexity by reducing the number of interfering peaks in the LC and reducing signal suppression by providing clean samples for the MS.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Waters_Corporation_Oasis_SPE_LC_MS_MS_chromatogram_of_1_pgm_L_of_alprazolam_from_rat_plasma_8b7275b25b.jpg" alt="Waters: Oasis SPE - LC-MS-MS chromatogram of 1 pgmL of alprazolam from rat plasma" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Waters_Corporation_Oasis_SPE_LC_MS_MS_chromatogram_of_1_pgm_L_of_alprazolam_from_rat_plasma_8b7275b25b.jpg 169w," sizes="100vw" width="1024" height="946"><h4>Get the cleanest extracts with the Oasis 2x4 method</h4>Having a variety of tools for method development allows separation scientists to optimize protocols for maximum sensitivity and selectivity. The Oasis 2x4 method for SPE sorbent and protocol selection for acids, bases, and neutrals produces the cleanest extracts – all by eliminating matrix interferences and sample variability. Get the flexibility to extract acids, bases, and neutrals with high SPE recoveries while removing matrix components that may interfere with analysis with our two protocols and four sorbents. By following the simple steps outlined in the Oasis 2x4 method, you can achieve high recoveries and the cleanest extracts.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Waters_Oasis_2x4_protokol_pro_vyvoj_metody_c417be9006/Waters-Oasis-2x4-protokol-pro-vyvoj-metody.jpg" alt="Waters: Oasis SPE - Oasis 2 x 4 method development protocol." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Waters_Oasis_2x4_protokol_pro_vyvoj_metody_c417be9006/thumbnail_Waters-Oasis-2x4-protokol-pro-vyvoj-metody.jpg 242w," sizes="100vw" width="1519" height="979"><h4>Isolate your compounds with the Oasis HLB method</h4>Solid-phase extraction (SPE) method development starts with knowledge of the sample matrix—the nature and relative concentration of the analytes of interest and potentially interfering endogenous compounds. The right sorbent and solvents are selected for load, wash, and elute steps, resulting in the creation of rugged, reliable, and selective protocols. The Oasis HLB method is a generic protocol used to isolate a broad range of acidic, basic, and neutral compounds from a wide spectrum of matrices.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Waters_Corporation_Oasis_SPE_Generic_Method_Protocol_with_Oasis_HLB_SPE_83d684704d.jpg" alt="Waters: Oasis SPE - Generic Method Protocol with Oasis HLB SPE" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Waters_Corporation_Oasis_SPE_Generic_Method_Protocol_with_Oasis_HLB_SPE_83d684704d.jpg 139w," sizes="100vw" width="1024" height="1153"><h4>Multiple contaminant analysis with the 2-step pass-through protocol</h4>If you are doing multiple residue screening of veterinary drugs, pesticides and mycotoxins in various food matrices, you may be facing a high concentration of organic solvents. With our simple 2-step protocol (pass-through SPE), you can remove matrix interferences quickly if your samples contain a high concentration of organic solvent(s) and concentration and/or salt removal is not required. It can be used as the clean-up method following QuEChERS extraction, saving you significant time compared to the traditional dispersive SPE method - all while achieving superior clean-up.To do pass-through SPE, Waters offers 2 convenient and flexible formats:<ul><li>Traditional-style cartridges compatible with vacuum and positive pressure manifolds&nbsp;</li><li>"Plus" style cartridges that can be used without manifolds when connected to a displacement syringe</li></ul><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Waters_Oasis_SPE_kolonky_3_b4da6242de/Waters-Oasis-SPE-kolonky-3.jpg" alt="Waters: Oasis Plus Light and Plus Short Cartridges for 2-step pass through protocol." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Waters_Oasis_SPE_kolonky_3_b4da6242de/thumbnail_Waters-Oasis-SPE-kolonky-3.jpg 152w," sizes="100vw" width="1308" height="1342">
