ALTERNARIA
EXTREMELY WIDESPREAD AND COMMON SPORE. COMMON IN SOIL, DEAD PLANTS, AND FOODSTUFFS.
IT IS OFTEN FOUND INDOORS GROWING ON CELLULOSIC MATERIALS AND AS SETTLED DUST ON
CARPETS, TEXTILES, ETC. POTENTIAL OPPORTUNISTIC HUMAN PATHOGEN. COMMONLY RECOGNIZED
AS TYPE I (HAY FEVER) AND TYPE III HYPERSENSITIVITY PNEUMONITIS.
CLADOSPORIUM
COMMONLY FOUND ON DEAD PLANTS, WOODY PLANTS, FOOD, STRAW, SOIL, PAINT AND TEXTILES.
COMMON CAUSE OF EXTRINSIC ASTHMA (IMMEDIATE-TYPE HYPERSENSITIVITY: TYPE I). ACUTE
SYMPTOMS INCLUDE EDEMA AND BRONCHIOSPASMS; CHRONIC CASES MAY DEVELOP PULMONARY
EMPHYSEMA.
RHODOTORULA
RHODOTORULA IS COMMONLY IDENTIFIED IN INDOOR AIR SAMPLES. THEY CAN CAUSE PROBLEMS IF A
PERSON HAS HAD PREVIOUS EXPOSURE AND DEVELOPED HYPERSENSITIVITY. YEAST CAN BE
ALLERGENIC TO SUSCEPTIBLE INDIVIDUALS WHEN PRESENT IN SUFFICIENT CONCENTRATIONS.
NON-SPORULATING FUNGI
MANY FUNGI DO NOT FORM SPORES USING ROUTINE GROWTH MEDIA AND UNDER NORMAL GROWTH
CONDITIONS IN THE LABORATORY. SPORES ARE VERY USEFUL TO HELP IDENTIFY THE FUNGUS.
NON-SPORULATING COLONIES ARE OFTEN A RESULT OF GERMINATING MUSHROOM SPORES
(BASIDIOSPORES). NON-SPORULATING FUNGI CAN POTENTIALLY BE ALLERGENIC, IRRITATING, OR
CAUSE HYPERSENSITIVITY PNEUMONITIS, AND DERMATITIS.
YEAST
VARIOUS YEASTS ARE COMMONLY IDENTIFIED ON AIR SAMPLES, BUT BEYOND THE NORMAL SCOPE OF
OUR TESTING. THE TERM "YEAST" AS USED IN THIS REPORT HAS NO TAXONOMIC STANDING AND
SIMPLY DENOTES A GROWTH FORM MUCH IN THE SAME WAY "MISTLETOE" DENOTES MANY DIFFERENT
PLANT SPECIES. THEY MAY CAUSE PROBLEMS IF A PERSON HAS HAD PREVIOUS EXPOSURE AND
DEVELOPED HYPERSENSITIVITY.
The samples in this report do not indicate the presence of elevated indoor mold spores or colonies for the specific locations only.
The mold identified in this report is often associated with excess moisture and can be a problem in indoor environments at high levels. Since mold requires water to
grow, it is important to prevent moisture problems in buildings. The presence of mold, water damage or musty odors should be addressed immediately. In all
instances, any source(s) of water must be stopped and the extent of water damage determined. Mold can grow on virtually any organic surface, as long as moisture
and oxygen are present. When excessive moisture accumulates in buildings or on building materials, mold growth will often occur, particularly if the moisture
problem remains undiscovered or unaddressed. Building materials, such as drywall are made of cellulose and are highly absorbent, perfect surfaces for mold growth
when wet. Moisture problems may include roof leaks, plumbing leaks, landscaping or gutters that direct water into or under the building, and unvented combustion
appliances such as gas stoves. Water damaged building materials supporting mold growth should be cleaned or replaced as quickly as possible in order to ensure a
healthy environment. Specific methods of assessing and remediating mold contamination should be based on the extent of visible contamination and the cause of
damage.
The most common symptoms of mold exposure are runny nose, eye irritation, cough, congestion, and aggravation of asthma. Individuals with persistent health
problems that appear to be related to mold or other types of air quality contaminant exposure should see their physicians for a referral to professionals who are
trained in occupational/environmental medicine or related specialties and are knowledgeable about these types of exposures. Decisions about removing individuals
from an affected area must be based on the results of such medical evaluation. Since mold is naturally present in outdoor environments and we share the same air
between the indoors and the outdoors, it is impossible to eliminate all mold and their spores from the indoor environment.
The detection limit of fungal analysis using optical microscopy is one fungal spore or one fungal structure. The quantitation limits vary from analysis to analysis and
from processing procedure to processing procedure. Contact us to determine your quantitation limits.
