Lysogenic Cycle of Bacteriophages00:43

Lysogenic Cycle of Bacteriophages

67.3K
In contrast to the lytic cycle, phages infecting bacteria via the lysogenic cycle do not immediately kill their host cell. Instead, they combine their genome with the host genome, allowing the bacteria to replicate the phage DNA along with the bacterial genome. The incorporated copy of the phage genome is called the prophage. Some prophages can re-activate and enter the lytic cycle. This often occurs in response to a perturbation, such as DNA damage, but can also transpire in the absence of...

Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

399
Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Bacterial Phylum Tenericutes01:24

Bacterial Phylum Tenericutes

434
The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...

Gene Regulation During Sporulation01:17

Gene Regulation During Sporulation

427
Sporulation is a complex developmental process that allows certain Gram-positive bacteria, such as Bacillus subtilis and Clostridium species, to survive extreme environmental conditions. This process is tightly regulated by a series of signaling cascades and transcriptional controls, ensuring the formation of a highly resistant endospore.Sporulation is triggered by unfavorable conditions, such as nutrient depletion, and is governed by a phosphorelay system. One of the sensor kinases, such as...

Lytic Cycle of Bacteriophages01:30

Lytic Cycle of Bacteriophages

77.3K
Bacteriophages, also known as phages, are specialized viruses that infect bacteria. A key characteristic of phages is their distinctive “head-tail” morphology. A phage begins the infection process (i.e., lytic cycle) by attaching to the outside of a bacterial cell. Attachment is accomplished via proteins in the phage tail that bind to specific receptor proteins on the outer surface of the bacterium. The tail injects the phage’s DNA genome into the bacterial cytoplasm. In the...

DNA Bacteriophages01:26

DNA Bacteriophages

773
Bacteriophages, or phages, are viruses that specifically infect bacteria, utilizing their genetic material to hijack host cellular machinery for replication. DNA bacteriophages employ single-stranded DNA (ssDNA) or double-stranded DNA (dsDNA) genomes. These phages exhibit diverse replication strategies and host interactions, influencing their ecological roles and applications in biotechnology and medicine.ssDNA BacteriophagesssDNA phages, with their small genomes, utilize unique strategies to...

Area of Science:

  • Microbiology
  • Virology
  • Bacteriology

Background:

  • Clostridium sporogenes is a ubiquitous, spore-forming anaerobic bacterium.
  • This bacterium is commonly found in the environment and is associated with food spoilage.
  • C. sporogenes also exists as a commensal organism within the mammalian gut microbiome.

Purpose of the Study:

  • To isolate and characterize bacteriophages capable of infecting Clostridium sporogenes.
  • To determine the genomic diversity of isolated phages.

Main Methods:

  • Isolation of bacteriophages from environmental samples.
  • Infection assays to confirm phage activity against C. sporogenes.
  • Whole-genome sequencing of isolated phages.

Main Results:

  • Successful isolation of multiple bacteriophages targeting C. sporogenes.
  • Identification of 30 unique phage genomes.
  • Phylogenetic analysis revealed that the isolated phages fall into three distinct congeneric species.

Conclusions:

  • The study demonstrates the existence of a diverse phage population targeting C. sporogenes.
  • These findings contribute to our understanding of phage-host interactions within the context of environmental and gut microbiomes.
  • The characterized phages represent potential tools for future applications, such as phage therapy or microbial control.
