How do lactobacilli help protect the vagina from potential pathogens?
Expert Solution & Answer
Summary Introduction
To review:
The way lactobacilli aid to protect the vagina from the pathogens.
Introduction:
Lactobacillus refers to the genus of the bacteria, which is facultatively anaerobic and Gram-positive and along with this it is rod-shaped and nonspore forming bacteria. These are also known to be the prime part of the lactic acid bacteria club and in humans, they contribute the significant element of the microbiota at different sites of the body.
Explanation of Solution
Vaginal flora or also known as vaginal microbiota refers to the microorganisms thatcolonize the vagina and they were found in the year of 1892. The type and the number of bacteria present consists of significant implications for the woman’s overall health and the primary colonizing bacteria present in the healthy individual refer to the genus called Lactobacillus. Thesebacteria produce lactic acid in the vagina and protect the vagina from infection of pathogenic species. The pH (potential of hydrogen) of this is low and it is accepted by the prime mechanism that controls the composition of the vaginal microflora.
Conclusion
Therefore, it can be concluded that the lactobacilli produce the lactic acid in the body, which prevents the vagina from infections.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
