Bacterial Phylum Verrucomicrobiota01:26

Bacterial Phylum Verrucomicrobiota

674
The phylum Verrucomicrobiota comprises at least four characterized orders, with most species classified within the order Verrucomicrobiotales. Members of this phylum are either aerobic or facultatively aerobic, with the ability to ferment sugars. A notable exception is the genus Methylacidiphilum, which consists of aerobic methanotrophs. Additionally, some Verrucomicrobiota establish symbiotic relationships with protists. These bacteria are widely distributed across various environments,...

Bacterial Signaling01:30

Bacterial Signaling

42.8K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

Surface Membrane Barriers01:18

Surface Membrane Barriers

3.3K
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Bacterial Transformation

62.4K
In 1928, bacteriologist Frederick Griffith worked on a vaccine for pneumonia, which is caused by Streptococcus pneumoniae bacteria. Griffith studied two pneumonia strains in mice: one pathogenic and one non-pathogenic. Only the pathogenic strain killed host mice.
Griffith made an unexpected discovery when he killed the pathogenic strain and mixed its remains with the live, non-pathogenic strain. Not only did the mixture kill host mice, but it also contained living pathogenic bacteria that...

Bacterial Phylum Bacteroidota01:26

Bacterial Phylum Bacteroidota

801
The phylum Bacteroidota includes over 700 species classified into four primary orders: Bacteroidales, Cytophagales, Flavobacteriales, and Sphingobacteriales. These gram-negative, non-sporulating rods exhibit saccharolytic capabilities and can be aerobic or fermentative, encompassing obligate aerobes, facultative aerobes, and obligate anaerobes. Many species display gliding motility, though some are nonmotile or use flagella. The genus Bacteroides is well-studied due to its significant role in...

Bacterial Phylum Chlamydiae01:29

Bacterial Phylum Chlamydiae

689
The phylum Chlamydiae or Chlamydiota is composed of a single order, Chlamydiales. This phylum consists entirely of obligate intracellular parasites that infect eukaryotic hosts. While human pathogens within this group have been studied extensively, the phylum encompasses many species capable of interacting with various eukaryotic organisms. Members of Chlamydiae are typically small cocci, approximately 0.5 μm in diameter, and exhibit a distinctive developmental cycle. As is characteristic...

Area of Science:

  • Gynecology
  • Microbiology
  • Public Health

Background:

  • Bacterial vaginosis (BV) is the primary cause of vaginal dysbacteriosis in women of reproductive age.
  • Its pathogenesis involves complex bacterial communities, including non-cultivable anaerobic populations, making treatment challenging.
  • BV is associated with increased risks of sexually transmitted infections (STIs), HIV, and pregnancy complications.

  • Review of existing literature on bacterial vaginosis (BV).
  • Analysis of diagnostic criteria, including Gram stain and Amsel criteria.
  • Discussion of treatment challenges, particularly recurrence.

Main Results:

  • BV is characterized by an imbalance in vaginal microbiota, leading to discharge and odor.

  • Recurrence remains a significant challenge in BV management.

Conclusions:

  • Bacterial vaginosis (BV) requires further research due to its complex etiology and treatment difficulties.
