Surface Membrane Barriers01:18

Surface Membrane Barriers

1.5K
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...

Vagina01:26

Vagina

9.8K
The vaginal canal is a tubular structure averaging about 10 cm in length that acts as the entryway to the female reproductive system and the passageway for menstrual flow and childbirth. The interior walls of the vagina exhibit concentric folds called rugae and are topped by an area known as the fornix, which connects with the protruding cervical portion of the uterus. This canal is comprised of an external fibrous layer, a muscular middle layer, and an inner lining with mucosal rugae, which...

Defense Mechanism Against Infection

7.2K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Chemical Agents for Microbial Control01:27

Chemical Agents for Microbial Control

199
Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...

Biological Methods for Microbial Control

197
Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...

Methods for Controlling Microbial Growth01:29

Methods for Controlling Microbial Growth

472
Microbial growth control refers to various methods employed to inhibit, reduce, or eliminate microorganisms to ensure safety and hygiene across different settings. These methods are categorized based on the target environment and the level of microbial control required.Biocides are versatile agents designed to control microorganisms by either inhibiting their growth or outright killing them. These agents work through various physical, chemical, mechanical, or biological mechanisms. The...

Area of Science:

  • Pharmacology and Nanotechnology
  • Microbiology
  • Women's Health

Background:

  • Vaginal infections are a global health concern with limited treatment options and increasing drug resistance.
  • Phytochemicals, like those from myrtle (Myrtus communis L.), offer potential antimicrobial, antioxidant, and anti-inflammatory properties.
  • There is a critical need for novel antimicrobial strategies to address the limitations of current therapies for vaginal infections.

Purpose of the Study:

  • To develop and evaluate novel nanodevices for delivering myrtle plant extracts (leaves, seeds, fruit) in the vaginal environment.
  • To investigate the efficacy of these myrtle-loaded nanodevices against common vaginal pathogens and their impact on human cells and resident microflora.
  • To explore the potential of myrtle-derived nanotherapies for treating vaginal infections.

Main Methods:

  • Fabrication of Polycaprolactone-Gelatin nanofibers encapsulating myrtle leaf extract and soaking with myrtle seed extract.
  • In vitro testing of nanodevices against vaginal pathogens: Trichomonas vaginalis, Escherichia coli, Staphylococcus aureus, and various Candida species.
  • Assessment of nanodevices' effects on human cell lines (HeLa, Human Foreskin Fibroblast-1, skin stem cells) and Lactobacillus acidophilus viability.

Main Results:

  • Nanofibers loaded with myrtle leaf and seed extracts demonstrated varying capabilities in inhibiting microbial proliferation.
  • The developed nanodevices showed no adverse effects on the viability of human cells and the resident vaginal microflora (Lactobacillus acidophilus).
  • Specific nanofiber formulations exhibited significant antimicrobial activity against tested vaginal pathogens.

Conclusions:

  • Myrtle (Myrtus communis L.) extract-loaded nanodevices are promising candidates for developing new treatments for vaginal infections.
  • These nanodevices offer a potentially safe and effective approach by targeting pathogens without compromising beneficial microflora or host cells.
  • Further research and development of these nanotechnological delivery systems could lead to advanced therapies for women's health.
