Universityof Coloradoresearchers study determines dog dung bacteria taking over air quality

The researchers had taken samples of the winter air in four Midwestern cities noting that they had found bacteria in the air which is very much like dung dog. The samples of the air had been compared with a database of bacteria found on soil, leafs, feces from people, cow and dogs.

The study has been published July 29th in “Applied and Environmental Microbiology”.

According to lead author of this study, Robert Bowers, graduated student in the university’s ecology and evolutionary biology department and the Cooperative Institute for Research in Environmental Services (CIRES) based at the university, remarked that researchers had discovered surprisingly high bacterial variances in all of their samples. However, the most surprising discovery was the airborne bacteria in communities of Detroit and Cleveland most similarly looked like those communities found in dog dung. This advocates that dog dung could be a possible source of bacteria to the atmosphere at those locations.

This study was in attempts of researchers having a better understanding of exactly what microbes distribute in urban environments according to a news release by the university. The samples taken in summer and winter in Chicago, Cleveland, Detroit and a very small town in Mayville, Wisconsin.

Dr. Noah Fierer, PhD, assistant professor at the university in the department of ecology and evolutionary biology and CIRES fellow, states "We breathe in bacteria every minute we are outside, and some of these bugs may have potential health implications."

Dr. Fierer further notes that scientists already are aware of bacteria existing in the atmosphere and these bacteria can have an adverse effect on human health such as triggering allergic asthma and seasonal allergies.

According to Dr. Bowers in summertime bacteria comes from numerous sources such as dust and lakes. In the wintertime however, leaves drop and snow covers the ground, the access that these environments have as sources also decreases. It is at the time during this season that airborne communities seem to be more affected by dog dung than the other sources tested in the study.

We may not be able to do much about improving outside air quality but there are things you can do to improve the air you breathe indoors.


Houseplants are usually looked at as room décor but in reality they aide in removing pollutants and toxins in the air.

Suggestions indicate that one plant covers 10 square yards of floor space based on ceiling height of eight to nine feet. Here is a list of the ten most effective house plants. If the plant appears in italic print it is not safe for pets.

Areca palm

Reed palm

Dwarf date palm

Boston fern

Janet Craig dracaena

English ivy

Australian sword fern

Peace Lily

Rubber plant

Weeping fig

In May this year “The State of Air 2011 Report” by the American Lung Association had listed the most polluted cities in the United States, Detroit had ranked number 17 out of 25 and tied with the cities of Houston and St. Louis.

Air Duct Cleaning

Heating, ventilation and air conditioning systems can breed mold, fungus and other bacteria, leading to poor indoor air quality.

Air duct cleaning services use specialized powerful vacuum which removes the containments in the indoor air.

Air duct cleaning service can cost in the range of $400 to $800 on a average sized home. The good news is the cleaning is only needed every three to five years. Using $400.00 and three years you would average a cost of around eleven dollars a month to have clean indoor air quality. It just may be worth the investment.

WebMD Health Ehome offers five easy tips you can take to improve indoor air quality.
