It’s impossible to say from staph skin infection pictures, if the cause of infection is MRSA (Methicilin Resistant Staphylococcus Aureus) or an “usual” staph - MSSA (Methicillin Sensitive Staphylococcus Aureus). Even a staph carrier without any symptoms can have MRSA. Folliculitis, which is usually a mild infection, may also be caused by MRSA or MSSA (folliculitis pictures).

Nature has created a very useful and balanced environment for all the living things to live in a peaceful and joyful world ensuring their health at the maximum. Natural environment is the key to the survival of the various species and a slight change in any of the components of an environment proves fatal to the organisms living in it. In biological terms a natural befitting environment in which a number of species live together while co-operating and coordinating with one another is called an ecosystem and the study of relationship between an organism and its environment is called Ecology.
Composition and working of Human Environment
Same is the case with man whose natural environment is “the earth” and its surroundings where he lives. Human ecosystem or environment has two main factors; i.e. biotic factors and Abiotic factors. Biotic factors involve only the living factors whereas Abiotic factors are the non living factors both of which are responsible for the normal working of an ecosystem. If there keeps a fine natural balance between the two types of factors, all goes well for the organisms and they live on happily. But on the other hand, if any of the components is not working properly, the whole ecosystem gets disturbed and the organisms can never lead a normal happy life in such an abnormal ecosystem. Then it becomes very much important to set right the ecosystem as early as possible by removing the causes of disturbance so that the normal living of the organisms may be ensured. Such is the importance of an environment for a species.
If we look for a donkey with horns, we may succeed to find but sorry to say in this so-called civilized and modern age we can’t get some fresh air to take deep breaths. Pollution is one of those gifts this modern rapid, fast progress in industrialization offers to humankind.
It wasn’t convincingly realized before but now some researches suggest that even low levels of pollution can also be dangerous for the heart and lungs. The analyses of the researchers were published this week in the New England Journal of Medicine. The researchers focused on how small particles that were found in the air affected the function of lungs. In this new research, some studies that were published in the same journal earlier this year were also defended by the researchers. In those previous studies it was shown, how air pollution contributed to heart problems. Is it a grave issue or need not to be worry? U.S. news asked some key questions from renowned experts in this connection.
How can you define particulate pollution?
A report from American Lung Association defines particulate pollution as a mixture of solid and liquid elements in the air that comes from natural sources as wildfires and dust storms, human activities as to burn fossil fuels in the factories or to use diesel engines. Some other particles also take place when some chemicals or materials act in response with another chemical or material in the atmosphere.
