Air microbiology study of microbes suspended in air. Microflora of air depend on the location and environmental condition at particular place. There are different types of air trapping devices like Slit Sampler, Andersons samplers, Impingers etc. Air borne diseases mainly spread by droplet infection, contact with infected things . Air borne diseases are discussed and concluded with control of air borne microbes.
Microbial interactions are ubiquitous, diverse, critically important in the function of any biological community.
The most common cooperative interactions seen in microbial systems are mutually beneficial. The interactions between the two populations are classified according to whether both populations and one of them benefit from the associations, or one or both populations are negatively affected.

Introduction to Microbiology & Microorganisms PPT by DR.C.P.PinceDR.PRINCE C P
Microorganisms are the minute living bodies not visible to the naked eyes.Example: Bacteria, Yeast, Amoeba etc
Microbiology is the specific branch of ‘biology’ that deals with the elaborated investigation of ‘small organisms’ termed as microbes or Microorganisms.
In simple words, Microbiology is the study of microorganisms.
Bacteria Example: Anthrax Bacilli, Esch. Coli
Fungi - .Example: Yeast, Mushrooms, Pencillium
Algae Example: Diatoms
Protozoan Example : Malaria parasite
Viruses - Example:HIV,Chicken pox
Worms – Example: Round worm, Pin worm

A SEMINAR REPORT ON AIR MICROFLORA.
In addition to gases, dust particles and water vapour, air also contains microorganisms. There are vegetative cells and spores of bacteria, fungi and algae, viruses and protozoan cysts (Rintala et al., 2018).
Since air is often exposed to sunlight, it has a higher temperature and less moisture. So, if not protected from desiccation, most of these microbial forms will die. Air is mainly it transport or dispersal medium for microorganisms (Rintala et al., 2018).
They occur in relatively small numbers in air when compared with soil or water. The microflora of air can be studied under two headings outdoor and indoor microflora (Rintala et al., 2018).
The use of high efficient particulate air filters and immunization should be employed to control the spread of these airborne diseases. Obviously, the presence of a good ventilation system inside buildings eliminates to some extent the influence of indoor and outdoor sources. Proper ventilation helps to dilute the negative effects of indoor and outdoor air.

The Importance of Air Microbiology in a Rapidly Changing World.docxHamza Mbareche
The pandemic prompted heightened interest in air microbiology just as climate change causes increasing global atmospheric circulation. Physicochemical properties of the atmosphere like solar radiation, wind, temperature and air pressure play a major role in the survival and spread of pathogenic bioaerosols.

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

NVBDCP.pptx Nation vector borne disease control programSapna Thakur
NVBDCP was launched in 2003-2004 . Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding arthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.
3. During 1930s the term aeromicrobiology was used to denote the air borne spores (e.g. fungi and other microorganisms ) Further in 1951 ,the term was elaborated to include dispersion of insect population, fungal spores, bacteria and viruses. In 1964, the term included the research work of air borne materials of biological significance.

5. It is the study of those invisible microorganisms (which are less 1mm in size & not visible through naked eyes) which are present in air.
6. Study of aerosolization, aerial transmission and biological materials. It also includes the study of diseases transmitted through respiratory routes. The field of aeromicrobiology is important as it involves, Formation of aerosols . Their transmission and deposition in soil.
7. The important gases that effect the microorganisms are hydrogen sulphide, sulphur dioxide, carbon monoxide, chlorine, hydrogen fluoride, ozone , etc. The microbial forms are bacteria, fungi and actinomycetes , algae, spores of pteridophytes, pollen grains, micro insects and viruses.
