On top of that, interactions between the microbiome and our body and our lifestyle multiply the complexity even more.<br /> <br /> This article explores five different views of the microbiome and how it fits into our body (or how the body fits in with the microbiome). From the organ view to the ecosystem view, each is a different way of looking at the different functions, dynamic patterns, and integration of the microbiome in its host, and each provides guidance for how to approach treatment of disease and maintenance of health.<br /> <br /> <strong>Journal Paper:</strong><br /> Morar N, Bohannan BJM. 2019. <a href= "https://www.journals.uchicago.edu/doi/10.1086/703582" target= "_blank" rel="noopener">The Conceptual Ecology of the Human Microbiome</a>.

In this case, the system bacteria maintaining their particular cell shape.<br /> <br /> Spherical cells have it easier: just add more cell material at every point. But for rods, they must make the cell longer without making it wider. How do they accomplish this? Two groups of proteins work together to help rod-shaped species grow, but how they work wasn't specifically known.<br /> <br /> In this study, it was found that one group of proteins adds more cell material as it moves around the circumference, while the other adds structure to the cell that allows it to maintain shape. The more of these structural proteins present, the thinner the cell can stay.<br /> <br /> <strong>Journal Paper:</strong><br /> Dion MF, Kapoor M, Sun Y, Wilson S, Ryan J, Vigouroux A, van Teeffelen S, Oldenbourg R, Garner EC. 2019. <a href= "https://www.nature.com/articles/s41564-019-0439-0" target="_blank" rel="noopener"><em>Bacillus subtilis</em> cell diameter is determined by the opposing actions of two distinct cell wall synthetic systems</a>.

393: Prokaryote Partner Prevents Pathogen Potency
<p>This episode: Bacterial symbionts of amoebas help them survive bacterial infection, and prevent pathogens from spreading to others as much!</p> <p><span style="font-size: medium;"><a href= "http://traffic.libsyn.com/bacteriofiles/BF393.mp3">Download Episode</a></span> (7.5 MB, 8.1 minutes)<br /> <br /> <span style="font-weight: bold;">Show notes:</span><br /> Microbe of the episode: <em><a href= "https://ijs.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-26-2-238" target="_blank" rel="noopener">Eubacterium dolichum</a></em><br /> <br /> <a href="https://phys.org/news/2019-05-symbionts-lifesavers.html" target="_blank" rel="noopener">News item</a><br /> <br /> <strong>Takeaways</strong><br /> Amoebas are free-living, single-celled organisms, but they have some things in common with some cells of our immune system (macrophages). For example, certain bacterial pathogens can infect both in similar ways. So it can be useful to study the interactions of amoebas and bacteria to learn about our own immune defenses.<br /> <br /> In this study, the amoeba <em>Acanthamoeba castellanii</em> has another bacterial symbiont that helps it resist killing by the bacterial pathogen <em>Legionella pneumophila</em>. Once the amoebas recovered from the infection, they were more resistant to future challenges. Even better, the symbiont prevented the pathogen from transforming into a more spreadable form like it does when infecting amoebas alone.<br /> <br /> <strong>Journal Paper:</strong><br /> König L, Wentrup C, Schulz F, Wascher F, Escola S, Swanson MS, Buchrieser C, Horn M. 2019. <a href= "https://mbio.asm.org/content/10/3/e00333-19" target="_blank" rel= "noopener">Symbiont-Mediated Defense against <em>Legionella pneumophila</em> in Amoebae</a>. mBio 10:e00333-19.</p> <p><span style="font-weight: bold;">Other interesting stories:</span></p> <div style="margin-left: 2em;"> <div style="margin-left: 2em"> <ul> <li><a href= "https://www.sciencedaily.com/releases/2019/05/190530160647.htm" target="_blank" rel="noopener">RNA-cutting CRISPR/Cas system induces bacterial dormancy to prevent phage replication</a></li> <li><a href="https://www.nature.com/articles/s41586-019-1291-3" target="_blank" rel="noopener">Gut bacteria degrade/modify many different kinds of drugs</a> (paper)</li> </ul> </div> </div> <p> </p> <p>Email questions or comments to <a href= "mailto:bacteriofiles@gmail.com">bacteriofiles at gmail dot com</a>.

These are called magnetotactic, and they use this ability to swim toward or away from the surface of their aquatic habitat, to adjust their oxygen exposure according to their preference.<br /> <br /> No eukaryotic microbes have yet been discovered that can sense and react to magnetic fields like these prokaryotes. In this study, however, a protist was discovered that can do it via its partnership with ectosymbionts, or bacteria attached to its surface, that sense magnetism and orient their host's movement. In return, factors of the host's metabolism may feed its symbionts.<br /> <br /> <strong>Journal Paper:</strong><br /> Monteil CL, Vallenet D, Menguy N, Benzerara K, Barbe V, Fouteau S, Cruaud C, Floriani M, Viollier E, Adryanczyk G, Leonhardt N, Faivre D, Pignol D, López-García P, Weld RJ, Lefevre CT. 2019. <a href= "https://www.nature.com/articles/s41564-019-0432-7" target="_blank" rel="noopener">Ectosymbiotic bacteria at the origin of magnetoreception in a marine protist</a>.

391: Slime Stores Sodium Sensibility
<p>This episode: Slime molds can learn to get used to salt and hold on to that memory even after a period of dormancy!</p> <p><span style="font-size: medium;"><a href= "http://traffic.libsyn.com/bacteriofiles/BF391.mp3">Download Episode</a></span> (8.9 MB, 9.7 minutes)<br /> <br /> <span style="font-weight: bold;">Show notes:</span><br /> Microbe of the episode: <em>Nocardia transvalensis</em><br /> <br /> <a href= "https://phys.org/news/2019-04-slime-mold-absorbs-substances.html" target="_blank" rel="noopener">News item</a><br /> <br /> <strong>Takeaways</strong><br /> Slime mold <em>Physarum polycephalum</em> has many surprisingly intelligent abilities, despite being only a single cell. Studying how these abilities work in the cell can teach us new ways that life can do things. The ability of interest here is habituation, or learning not to avoid a chemical that seems unpleasant to the cell but is not necessarily harmful, especially with a food reward.<br /> <br /> The slime mold can become habituated to salt, in this case, learning to tolerate it enough to pass through a gradient of increasing concentration to get to some food as quickly as it crosses the same distance with no salt present. The scientists here learned that the cell takes up sodium into itself as it habituates, and holds onto both sodium and its memory through a period of hibernation.<br /> <br /> <strong>Journal Paper:</strong><br /> Boussard A., Delescluse J., Pérez-Escudero A., Dussutour A. 2019. <a href= "https://royalsocietypublishing.org/doi/10.1098/rstb.2018.0368" target="_blank" rel="noopener">Memory inception and preservation in slime moulds: the quest for a common mechanism</a>.

390: Friendly Phages Find Foes

But in order to cooperate or compete, bacteria must first be able to identify and discriminate between themselves and others. Sometimes microbes do this by exchanging membrane molecules, or secreting chemical signals that only partners can detect, or transferring plasmids or producing antimicrobial compounds that kill competitors.<br /> <br /> In the current study, scientists discovered a strain of <em>E. coli</em> that carries around phages that help them distinguish other strains and compete with them. When this strain encounters another, the phages it carries attack and destroy cells of the other strain, while leaving the carrier strain mostly unharmed. This strategy is not without cost, though; the viral proteins take resources to produce, and when there's no competing strains around, the virus can attack its carrier to some extent.<br /> <br /> <strong>Journal Paper:</strong><br /> Song S, Guo Y, Kim J-S, Wang X, Wood TK. 2019. <a href= "https://www.cell.com/cell-reports/abstract/S2211-1247(19)30400-0" target="_blank" rel="noopener">Phages Mediate Bacterial Self-Recognition.</a> Cell Reports 27:737-749.e4.</p> <p><span style="font-weight: bold;">Other interesting stories:</span></p> <div style="margin-left: 2em;"> <div style="margin-left: 2em"> <ul> <li><a href= "https://phys.org/news/2019-05-bacteria-behavior-tackle-tiny-obstacle.html" target="_blank" rel="noopener"><em>E. coli</em> adjusts its swimming to get around obstacles</a></li> </ul> </div> </div> <p> </p> <p>Email questions or comments to <a href= "mailto:bacteriofiles@gmail.com">bacteriofiles at gmail dot com</a>.

Preventing this usually requires careful control, such as keeping humidity low, for storing paper for long periods.<br /> <br /> In this study, scientists tested the ability of the bacterium <em>Lysobacter enzymogenes</em> to protect paper via the antifungal compounds it produces. This first required filtering out the pigments that the bacteria produced, to prevent them from discoloring the paper. Once a method for this filtering was in place, they found the bacterial culture supernatant could significantly reduce fungal growth on various kinds of paper, and protect the paper from staining and degradation.<br /> <br /> <strong>Journal Paper:</strong><br /> Chen Z, Zou J, Chen B, Du L, Wang M. 2019. <a href= "https://onlinelibrary.wiley.com/doi/abs/10.1111/jam.14265" target= "_blank" rel="noopener">Protecting books from mold damage by decreasing paper bioreceptivity to fungal attack using de-coloured cell-free supernatant of <em>Lysobacter enzymogenes</em> C3</a>.

It's similar to macrophages or white blood cells as part of our immune system in our bodies.<br /> <br /> The prey of amoebas includes bacteria, large viruses, and single-celled fungi called yeasts. In this study, scientists showed that some yeasts make great food sources for a certain kind of amoeba called <em>Protostelium aurantium</em>, while others either lack nutritional value or hide from the predators by covering up certain recognition molecules on their cell wall.<br /> <br /> They found that the amoebas could also consume the spores of filamentous fungi, and could even attack the filaments, or hyphae. In this latter case, instead of engulfing the large filaments, they pierced the cells and extracted their contents, an approach named ruphocytosis, from the Greek for suck or slurp.<br /> <br /> <strong>Journal Paper:</strong><br /> Radosa S, Ferling I, Sprague JL, Westermann M, Hillmann F. <a href= "https://onlinelibrary.wiley.com/doi/abs/10.1111/1462-2920.14588" target="_blank" rel="noopener">The different morphologies of yeast and filamentous fungi trigger distinct killing and feeding mechanisms in a fungivorous amoeba</a>.

New imaging technologies for diagnosis and analysis of cancer and for cancer research can be very valuable, especially if they don't require big investments of money and space.<br /> <br /> One promising imaging technology is called multispectral optoacoustic imaging, or MSOT. This uses pulses of light to create vibrations as pigments in tissues absorb the light and undergo thermal expansion; these vibrations are then detected by ultrasound technology. This approach allows good resolution and depth of imaging without large equipment like MRI machines, but the best results require adding pigments into the body.<br /> <br /> In this study, scientists showed that the photosynthetic pigments of purple non-sulfur bacteria can be useful in this optoacoustic imaging, providing a somewhat long-term, nontoxic approach. It proved especially interesting when they discovered that the wavelength spectrum changing over time was an indication of macrophage activity in the tumors.<br /> <br /> <strong>Journal Paper:</strong><br /> Peters L, Weidenfeld I, Klemm U, Loeschcke A, Weihmann R, Jaeger K-E, Drepper T, Ntziachristos V, Stiel AC. 2019. <a href= "https://www.nature.com/articles/s41467-019-09081-5" target= "_blank" rel="noopener">Phototrophic purple bacteria as optoacoustic <em>in vivo</em> reporters of macrophage activity</a>.

Plants and microbes make good partners by each contributing something the other needs. Plants make sugars via photosynthesis that microbes can use as food, and microbes can gather nutrients that plants can't make, can drive off pathogens, and can contribute to plant growth in other ways.<br /> <br /> However, plants aren't making sugars all the time, because the sun goes down every day. So what do partner microbes do at these times? In this study, a beneficial microbe <em>Herbaspirillum seropedicae</em> was found to produce a storage compound called polyhydroxyalkanoate, or PHA, that it could use to store food for times of scarcity.

Plants and other phototrophs—photosynthetic organisms that get their energy mainly from light—form the foundation of the food web, and organisms that feed on them or that feed on organisms that feed on them are all dependent on the ability to capture the sun's rays.<br /> <br /> There are other ways to benefit directly from the sun's energy, besides photosynthesis—some microbes have enzymes that use light energy to repair damage to DNA (the same damage that is caused by ultraviolet light), and we use sunlight to synthesize vitamin D.<br /> <br /> In this study, however, microbes are discovered to grow faster in the presence of light despite not being phototrophs or producing any light-harvesting proteins. The scientists discover some possible light-sensing proteins, though, that could regulate these microbes' behavior, allowing them to synchronize their growth cycles to phototroph partners in aquatic environments.</p> <p><br /> <strong>Journal Paper:</strong><br /> Maresca JA, Keffer JL, Hempel P, Polson SW, Shevchenko O, Bhavsar J, Powell D, Miller KJ, Singh A, Hahn MW. <a href= "https://jb.asm.org/content/early/2019/01/23/JB.00740-18" target= "_blank" rel="noopener">Light modulates the physiology of non-phototrophic Actinobacteria</a>.

Even within the group called giant viruses there is a large amount of variety. Many of their genes are unknown, without homology to any other sequences we have acquired in other areas of life. There is great potential to learn interesting things from these viruses.<br /> <br /> In this study, a new giant virus is discovered. Like many others, this infects amoebas, and causes them to transform from dynamic, shape-shifting cells into hard little cyst-like circles. This ability gave it the name Medusavirus. It's the first giant virus found in a relatively hot environment (a hot spring), and among other interesting features, it shows signs of multiple instances of gene transfer to and from its amoeba host.<br /> <br /> <strong>Journal Paper:</strong><br /> Yoshikawa G, Blanc-Mathieu R, Song C, Kayama Y, Mochizuki T, Murata K, Ogata H, Takemura M. 2019. <a href= "https://jvi.asm.org/content/early/2019/02/04/JVI.02130-18" target= "_blank" rel="noopener">Medusavirus, a novel large DNA virus discovered from hot spring water</a>.

377: Distributed Defense-Defeating Devices
<p>This episode: Newly discovered CRISPR-inhibiting genes are found in many different bacterial groups!</p> <p><span style="font-size: medium;"><a href= "http://traffic.libsyn.com/bacteriofiles/BF377.mp3">Download Episode</a></span> (8.0 MB, 8.8 minutes)<br /> <br /> <span style="font-weight: bold;">Show notes:</span><br /> Microbe of the episode: <em>Borrelia mazzottii</em><br /> <em><br /></em> <a href= "https://www.sciencedaily.com/releases/2019/02/190205144338.htm" target="_blank" rel="noopener">News item</a><br /> <br /> <strong>Takeaways</strong><br /> The discovery of the microbial immune system, CRISPR-Cas, changed many things about the way we think of microbial ecology and interactions with microbe-infecting viruses. The CRISPR-Cas system can learn to detect new threats by capturing bits of their genetic sequences and using these to target the Cas proteins to chop up any such sequences that make it into the cytoplasm. This can greatly increase microbial survival in certain ecosystems in which viruses regularly kill a large percentage of the microbial population.<br /> <br /> To overcome this defense, a virus has to adapt, either by acquiring mutations that change its sequence, thus escaping detection, or by acquiring anti-CRISPR proteins that shut down the microbial defense directly. These possibilities make the complex ecology even more interesting.<br /> <br /> In this study, scientists develop a clever method for screening for new anti-CRISPR genes, and go searching for them in samples from various places (soil, animal guts, human gut). They find several new examples, which turn out to be found in many different kinds of species in many different environments.<br /> <br /> <strong>Journal Paper:</strong><br /> Uribe RV, Helm E van der, Misiakou M-A, Lee S-W, Kol S, Sommer MOA. 2019. <a href= "https://www.cell.com/cell-host-microbe/abstract/S1931-3128(19)30040-X" target="_blank" rel="noopener">Discovery and Characterization of Cas9 Inhibitors Disseminated across Seven Bacterial Phyla</a>.

376: Pressurized Pollutant Pulls Products
<p>This episode: Supercritical carbon dioxide and bacteria that can grow in it make a great combination for biofuel production!</p> <p><span style="font-size: medium;"><a href= "http://traffic.libsyn.com/bacteriofiles/BF376.mp3">Download Episode</a></span> (9.4 MB, 10.2 minutes)<br /> <br /> <span style="font-weight: bold;">Show notes:</span><br /> Microbe of the episode: <em>Flexibacter aggregans</em><br /> <br /> <strong>Takeaways</strong><br /> Biofuels are an important part of humanity's move away from non-renewable resources. They have a higher energy density than batteries are yet able to achieve, giving them significant advantages for transportation purposes in which tapping into an electric grid isn't possible. Depending on the biofuel, they also have the advantage of existing infrastructure: we don't need to build a whole new system of charging or refueling stations, but can use the systems already in place.<br /> <br /> However, biofuels as a collection of technologies still need some refinements. Yields for the more potentially sustainable approaches are low, and the lower the concentration of a soluble fuel, the more difficult it is to separate it from the non-fuel components of a fermentation. Microbial products also face the risk of contamination of a fermentation by unwanted organisms that use up the substrate without producing desirable products.<br /> <br /> In this study, supercritical carbon dioxide is considered as a fix for both of these problems. The gas is pressurized to a point at which it is indistinguishable from liquid. A strain of <em>Bacillus megaterium</em> is specially selected as capable of growing and fermenting in this environment, while contaminants are inhibited. The solvent potential of supercritical carbon dioxide also serves as a way to extract the biofuel product—in this case, isobutanol—from the aqueous part of the culture medium. While it needs some development, this approach yields promising results.<br /> <br /> <strong>Journal Paper:</strong><br /> Boock JT, Freedman AJE, Tompsett GA, Muse SK, Allen AJ, Jackson LA, Castro-Dominguez B, Timko MT, Prather KLJ, Thompson JR. 2019. <a href="https://www.nature.com/articles/s41467-019-08486-6" target="_blank" rel="noopener">Engineered microbial biofuel production and recovery under supercritical carbon dioxide</a>.

There are about 8000 cases of this disease per year, and when treatment is unsuccessful, it can lead to the loss of one or both eyes.<br /> <br /> In this study, investigators looked into using a cancer-targeting, oncolytic virus to complement the normal treatment of chemotherapy. The virus for the most part remained localized to the eye where it should be, and targeted the cancer instead of healthy cells, and so seems promising. In the small trial with two patients included in this study, the virus didn't cause a complete recovery, but showed some modest promising results.<br /> <br /> <strong>Journal Paper:</strong><br /> Pascual-Pasto G, Bazan-Peregrino M, Olaciregui NG, Restrepo-Perdomo CA, Mato-Berciano A, Ottaviani D, Weber K, Correa G, Paco S, Vila-Ubach M, Cuadrado-Vilanova M, Castillo-Ecija H, Botteri G, Garcia-Gerique L, Moreno-Gilabert H, Gimenez-Alejandre M, Alonso-Lopez P, Farrera-Sal M, Torres-Manjon S, Ramos-Lozano D, Moreno R, Aerts I, Doz F, Cassoux N, Chapeaublanc E, Torrebadell M, Roldan M, König A, Suñol M, Claverol J, Lavarino C, De TC, Fu L, Radvanyi F, Munier FL, Catalá-Mora J, Mora J, Alemany R, Cascalló M, Chantada GL, Carcaboso AM. 2019. <a href= "http://stm.sciencemag.org/content/11/476/eaat9321" target="_blank" rel="noopener">Therapeutic targeting of the RB1 pathway in retinoblastoma with the oncolytic adenovirus VCN-01</a>.

All of these are competing with some and cooperating with others to try to survive and thrive the best they can.<br /> <br /> One interesting interaction takes place between small roundworms in the soil, called nematodes, and bacteria they carry around that cause disease in insects. These nematodes prey on insects by injecting the bacteria into them, which kill and start digesting the insects. The nematodes then feed on the insects and the bacteria until the resources have been exhausted, and then move on to the next insect, taking some bacteria with them again.<br /> <br /> In this study, the scientists wondered how these partners deal with competitors in the soil that might want to take advantage of their resources.

371: Cell Stalker Senses Signals
<p>This episode: Phages eavesdrop on bacterial communications to attack at the perfect moment!<br /> <br /> Thanks to Justin Silpe and Dr. Bonnie Bassler for their contributions!</p> <p><span style="font-size: medium;"><a href= "http://traffic.libsyn.com/bacteriofiles/BF371.mp3">Download Episode</a></span> (11.1 MB, 12.2 minutes)<br /> <br /> <span style="font-weight: bold;">Show notes:</span><br /> Microbe of the episode: Artichoke Aegean ringspot virus<br /> <br /> <a href= "https://www.sciencedaily.com/releases/2018/12/181213142206.htm" target="_blank" rel="noopener">News item</a><br /> <br /> <strong>Takeaways</strong><br /> Even organisms as small as bacteria can, and often do, communicate with each other through a process called quorum sensing, in which each cell releases a small amount of a certain chemical into their surroundings. When the population is large enough that the concentration of this chemical builds up to a certain level, the cells in the population change their behavior. The specifics of this change depend on the species and the situation.<br /> <br /> But since this chemical signal is released into the environment, anything around that can sense it can listen in on the communications of a bacterial population. In this study, Justin Silpe and Dr. Bonnie Bassler find a type of virus that uses such a chemical communication as a signal to come out of stasis and hijack a whole population of bacteria at once!<br /> <br /> Journal Paper:<br /> Silpe JE, Bassler BL. 2019. <a href= "https://www.cell.com/cell/abstract/S0092-8674(18)31458-2" target= "_blank" rel="noopener">A Host-Produced Quorum-Sensing Autoinducer Controls a Phage Lysis-Lysogeny Decision</a>.

And genetic modification, making specific changes at a specific place in a genome, is also difficult.<br /> <br /> Viruses can help with both delivery and modification, but they're often not specific and targeted enough to be effective, or even safe. Off-target effects could be harmful or even deadly, potentially resulting in cancer.<br /> <br /> In this study, a virus is modified with nanotechnology in the form of tiny magnets to allow humans to target it to specific tissues, and given the ability to modify specific genes using the bacterial CRISPR-Cas system. These modifications potentially make this gene delivery system much more safe and effective.<br /> <br /> Journal Paper:<br /> Zhu H, Zhang L, Tong S, Lee CM, Deshmukh H, Bao G. 2018. <a href= "https://www.nature.com/articles/s41551-018-0318-7" target="_blank" rel="noopener">Spatial control of in vivo CRISPR–Cas9 genome editing via nanomagnets</a>.

While the effects on fly fitness or behavior are not yet known, these results suggest that gut microbes, transmitted from parents to offspring, could be another mechanism of heritability.<br /> <br /> Journal Paper:<br /> Zare A, Johansson A-M, Karlsson E, Delhomme N, Stenberg P. 2018. <a href= "https://febs.onlinelibrary.wiley.com/doi/abs/10.1002/1873-3468.13278" target="_blank" rel="noopener">The gut microbiome participates in transgenerational inheritance of low-temperature responses in <em>Drosophila melanogaster</em></a>.
