In addition to our analytical services, Aerobiology Laboratory offers consulting services to professionals that have unique or complicated projects involving clinical pathogens, such as Cryptococcus neoforms, or Mycobacterium species, target organisms, such as Helicobacter pylori, unique niche organisms, such as sulfate-reducing bacteria and event related building IAQ with occupant exposure situations, such as a black water event involving E. coli/fecal coliforms and Enterococcus.
Contact the laboratory and discuss the details of your assessment with experienced microbiologists who have an extensive background in clinical and environmental microbiology.

We are able to support the implementation toward compliance to USP .|
Validation and Method Development
|Aerobiology offers expertise in diverse areas of tracking and identifying target microbials, product development stratgies for anti microbial products, an array of methods for product testing (See Product Validation page) and start up methods for product challenges..|
We offer consulting services and testing for target bacteria and fungi
Investigations are complex due to building structures, mechanical systems and engineering controls, various activities going on in building simultaneously, occupants health and external environmental situations. Aerobiology is experienced in helping clients develop a targeted sampling approach when looking for unique, targeted organism. Various medias, sampling equipment and sampling times enhance the sensitivity when looking for any specific microorganism.
|Bacillus Antracis||Bacillus anthracis is a spore-forming, Gram-positive, rod-shaped bacterium, 1 – 1.2um in width and 3 – 5um in length. It is the causative agent of anthrax. It lives in soils worldwide at mesophilic temperatures (10). It can be grown in aerobic or anaerobic conditons (facultative anaerobe). Bacillus anthracis is an important organism to study genome sequence because it’s used as a biological weapon. Culture method is performed in laboratory. TAT 48 hours.|
|Mycobacterium Tuberculosis and Rapid Growers||M. tuberculosis and other species of Mycobacterium are disease producing bacteria. The symptoms from infection range from full blown respiratory involvement to localized abscesses. Specialized laboratory procedures are used depending upon the target species implicated in the IAQ investigation. Contact the laboratory for appropriate sampling medias and collection techniques.|
|E.coli and Other Sewage Related Bacteria||Sewage screen testing allows simultaneous testing for the presence or absence of fecal coliform bacteria,E.coli and Fecal Streptococci or Enterococci. Colitag™ can detect fecal coliforms and E.coli bacteria at 1 cfu/ml within 24 hours even with as many as 2 million heterotrophic bacteria per 100 ml present. The Enterolert™ can detect fecal Streptococci or Enterococci at 1cfu/ml within 24 hrs per 100 ml of the sample present. Water, wipes and bulk samples can be used for testing.|
|Cryptococcus Neformans as Surrogate for Histoplasma Capsulatum||Cryptococcus neoformans is yeast like fungus that is known to be a human pathogen. According to the CDC, the infectious cases are on the rise due to the increase in the HIV cases and use of immunosuppressive drugs.Cryptococcus commonly isolated from soil that contains guano (bird droppings).Most species of Cryptococcus are seen distributed worldwide. They are commonly found in old pigeon dropping accumulation on high-rise buildings, window ledges, cupolas, towers etc. Cryptococcus can also be found in contaminated construction dusts as well. Contact the laboratory for appropriate sampling medias and collection techniques.|
|Legionella||Legionnaire’s disease caused by Legionella pneumophila is one of the most challenging building acquired diseases in the industrial hygiene community. According to CDC, over a year 8000 – 18,000 cases are estimated to be caused by Legionella. Most of the cases reported are sporadic and nosocomial infections. To date, there is 50 known species of Legionella and about 70 serogroups have been recognized to causes diseases in humans. The most common species of legionella that causes legionnaire’s disease is Legionella pneumophila serogroup 1.OCCURRENCE
The natural habitats of Legionella are environmental waters like lakes, streams, and rivers. They thrive in warm waters. Legionella sp. may be isolated from:
|Sulfate-Reducing Bacteria||Sulfate-reducing bacteria are a group of anaerobic bacteria that generate hydrogen sulfide. This by-product can cause a number of significant problems with water that range from a “rotten egg” odor to the blackening of equipment, slime formation, and initiation of corrosive processes. They mainly contribute to the tuberculation and galvanic corrosion of water mains, acid corrosion of metals and also destruction of concrete sewers. They can cause odor and taste problems in water and also biofouling of water wells. Sulfate-reducing bacteria are difficult to detect because they are anaerobic and tend to grow deep down within biofilms as a part of the microbial community.|
|Nitrifying Bacteria||Nitrates in water can be potential health risk, particularly to infants who have not yet developed a tolerance to nitrates. Aggressive nitrifying bacteria in waters may indicate the latter stages of aerobic degradation of nitrogen-rich matter. This can indicate that the water may have been polluted by nitrogen-rich organics from sources such as compromised septic tanks, sewage systems, and industrial and hazardous waste sites and is undergoing an aerobic form of degradation. They are of high importance in drinking water systems and wastewater affecting the quality of water. Nitrifying bacteria are also indicators of efficiency of purification process for waste water treatment.|
