Abstract

Insights

Corn silk extracts combat chronic mastitis in dairy cows by inhibiting biofilm formation in methicillin-resistant Staphylococcus aureus (MRSA). This natural remedy also enhances vancomycin effectiveness against these difficult-to-treat infections.

Area of Science:

  • Veterinary Medicine
  • Microbiology
  • Pharmacology

Background:

  • Mastitis, a significant dairy farm economic burden, is often caused by Staphylococcus aureus.
  • Biofilm formation by Staphylococcus aureus contributes to chronic mastitis, complicating treatment.
  • Methicillin resistance in Staphylococcus aureus (MRSA) presents a major therapeutic challenge.

Purpose of the Study:

  • To investigate the impact of Stigmata maydis (corn silk) on biofilm formation by MRSA.
  • To assess the effect of Stigmata maydis on vancomycin susceptibility in MRSA strains.

Main Methods:

  • Antibacterial activity assays were conducted.
  • Biofilm formation assays were performed.
  • Real-time reverse transcription PCR was utilized.
  • Experiments focused on MRSA strains from dairy cows with mastitis.

Main Results:

  • Aqueous extracts of Stigmata maydis demonstrated inhibition of MRSA biofilm formation.
  • Corn silk extracts increased vancomycin susceptibility in MRSA strains cultured under biofilm conditions.

Conclusions:

  • Stigmata maydis aqueous extracts effectively inhibit MRSA biofilm formation.
  • Corn silk enhances vancomycin efficacy against MRSA in biofilm states, offering a potential therapeutic strategy.

Buffer Effectiveness02:19

Buffer Effectiveness

Buffer solutions do not have an unlimited capacity to keep the pH relatively constant . Instead, the ability of a buffer solution to resist changes in pH relies on the presence of appreciable amounts of its conjugate weak acid-base pair. When enough strong acid or base is added to substantially lower the concentration of either member of the buffer pair, the buffering action within the solution is compromised.
The buffer capacity is the amount of acid or base that can be added to a given volume...

Biofilms01:29

Biofilms

Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...

Resistivity01:22

Resistivity

When a voltage is applied to a conductor, an electrical field is generated, and charges in the conductor feel the force due to the electrical field. The current density that results depends on the electrical field and the properties of the material. In some materials, including metals at a given temperature, the current density is approximately proportional to the electrical field. In these cases, the current density can be modeled as:

Resistance01:19

Resistance

When a current moves through any conductor, the conductor causes some level of difficulty for the current to flow. The measure of that difficulty is known as the resistance of the material and is represented by R. Every material has its own resistance. In the case of conductors, heat is emitted whenever a current passes through them. Resistance depends on the resistivity of the material. Resistivity is a characteristic of the material used to fabricate electrical components, whereas the...

Formation of Species01:31

Formation of Species

Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.

Resistance and Conductance01:25

Resistance and Conductance

A conductor's DC resistance at a given temperature is influenced by its resistivity, length, and cross-sectional area. Resistivity is an inherent property of the conductor material, with annealed copper serving as the international standard for measurement. For instance, the resistivity of hard-drawn aluminum at 20 degrees Celsius is 61% of the standard conductivity of annealed copper.
Various factors impact the resistance of a conductor. Spiraling in stranded conductors increases their...
