This document summarizes a lecture on the human oral microbiota. It defines oral microbiota as the microorganisms residing in the oral cavity. The oral cavity hosts a diverse ecosystem of microbes, including streptococcus, actinomyces, and fusobacterium species. These microbes colonize different oral sites as the oral environment changes with age. The microbiota exists in a symbiotic relationship with the host, but imbalances can lead to diseases like caries and periodontitis. Maintaining a balanced oral microbiota is important for both oral and general health.

Significance of microorganisms, Sagar Kumar RajakSagarKumar425
MICROORGANISMS USE IN DIFFERENT FIELDS
1. Decomposition of organic wastes and residues.
2. Production of antibiotics and other bioactive compounds.
3. Fixation of atmospheric nitrogen.
4. Suppression of soil-borne pathogens.
5. Recycling and increased availability of plant nutrients.
6. Degradation of toxicants, including pesticides.
7. Production of food for all organisms.
8. Remove of heavy metals to limit plant uptake.
9. Production of electricity.
10. Production of polysaccharides to improve soil aggregation.
11. Advantages:-
Microorganisms like bacteria decomposes organic waste into manure and increases the fertility of the soil.
Microorganisms help in fixing atmospheric nitrogen into nitrogen compounds in the soil and increases the fertility of the soil.
Microorganisms are used for making curd from milk, for making cheese, pickles, bread, cakes, pastries, alcohol, wine, vinegar (acetic acid) etc.
Microorganisms are used for making medicines.
Bioremediation is the process in which the micro-organisms are used to degrade the pollutants from the environment. Plants and micro-organisms are used to clean up the environment. Bioremediation is carried out by microbes and their metabolisms are used to remove the contaminants. Microbes have the ability to resolve the issue of contaminated ecosystem1. To improve or better living style the degradation of contaminated areas is very important. Importance of the biodegradation is increasing due to the expensiveness of the chemicals. So bioremediation is the best choice. The effluents should be degraded from the environment because they are very dangerous and have a bad impact on human beings. These pollutants sink into the water and cause pollution. These pollutants are treated with the help of microbes in bioremediation process. It is the best method because it is cost effective and eco-friendly. Different techniques of bioremediation are used to convert toxic substances into less toxic substances.

Understanding Fungal Skin Infections and Ringworm: Causes, Symptoms, and Trea...NoorulainMehmood1
Fungal skin infections, including the common condition known as ringworm, represent a significant dermatological concern affecting millions worldwide. This review delves into the multifaceted nature of fungal skin infections, elucidating their etiology, clinical manifestations, and therapeutic approaches. Fungal skin infections are caused by various species of fungi, with dermatophytes being the primary culprits behind ringworm. The clinical presentation of fungal skin infections varies, encompassing symptoms such as itching, redness, scaling, and characteristic circular lesions. Diagnosis typically involves clinical examination, microscopy, and culture of skin scrapings. Treatment strategies range from topical antifungal agents for mild cases to systemic therapy for severe or recurrent infections. Additionally, preventive measures and lifestyle modifications play pivotal roles in managing and preventing fungal skin infections. A comprehensive understanding of fungal skin infections, including ringworm, is essential for healthcare practitioners to facilitate timely diagnosis and effective management, thereby improving patient outcomes.
Key Words: Fungal skin infections, ringworm, dermatophytes, antifungal therapy, diagnosis, prevention, dermatology

21. Microbial flora exists in a harmonious relationship
with the host
if this relationship breaks down, disease can occur
in mouth this relationship is more prone to
breakdown than other parts of the body
Friday, March 23, 2012
22. Breakdown is usually associated with
major changes to the biology of mouth from exogenous
sources
presence of the microorganisms at sites not normally
accessible to them
such microorganisms are termed as
‘opportunistic pathogens’
