Using what you have learned about bacterial growth and reproduction, explain why following these suggestions would help to prevent the spread of antibiotic resistance. 3 days ago · An antibiotic is a drug that fights bacteria. Antibiotics can also be called antimicrobials, but this is a broader term that includes drugs that fight bacteria or other types of microbes, such as viruses or fungi. Antibiotics do not work against viruses, such as those that cause colds and flu. Antibiotics work in many different ways. Antimicrobial resistance (AMR or AR) occurs when microbes evolve mechanisms that protect them from the effects of antimicrobials. The term antibiotic resistance (AR or ABR) is a subset of AMR, as it applies to bacteria that become resistant to antibiotics. Resistant microbes are more difficult to treat, requiring higher doses, or alternative medications which may prove more toxic. |
February 5, The study has been published in Nature Communications. Antibiotic-resistant bacteria pose an increasing threat to human health, creating an urgent need for the development of novel antibiotics.
Taking Antibiotics
Most phages can cause their host cell to rupture, a process called lysis. They also release new "progeny" phage virions that are genetically and structurally identical to the parent virus. When the infected cell tries to divide, it blows up because it can't create the new cell wall between the daughter cells. The study focuses on characterizing the lysis genes of leviviruses, bacteriophages containing small single-stranded RNA genomes with only three to four genes. Tens of thousands of leviviruses have been discovered.
Among the known levivirus genes is Sgl, which stands for 'single gene Viruses Antibiotics And Antibiotics. Many here contain Sgl genes, but these have remained "hidden" from researchers as they are small, extremely varied and can be embedded within other genes.

In this study, researchers were able to identify 35 Viruse Sgls that produced a lytic or destructive effect on E. The team also determined that each Viruses Antibiotics And Antibiotics these Sgls could potentially represent a distinct mechanism for the lysis of host cells. Chamakura also noted previous research had shown that known single-stranded RNA phages have high mutation rates. In spite of a very short total length of genomic RNA, these phages can encode two or more Sgls or proto-Sgls for the lytic activity to destroy multiple bacterial hosts. Another far-reaching aspect of the study was the observation that a large proportion of the Sgls found in Viruses Antibiotics And Antibiotics investigation had originated and evolved within the gene for the phage replication protein, or Rep.
This could mean more highly divergent regions of the levivirus genome, such as the Rep gene, may serve as 'hotspots' for Sgl evolution. He said the study's examination of genomes also revealed that closely related phages showed significant evidence of the de novo gene evolution. In all, Chamakura said the research suggests Sgls are Vruses diverse and remain vastly untapped as a source for peptides that could be used in protein antibiotics to attack the cellular function of bacteria. And because these genes share little to no similarity with each other or to previously known Sgl genes, they represent a rich source for potential protein antibiotics.
