About our microbiology testing service
Our microbiology testing service can help you assess the risks from exposure to microorganisms or materials that may contain microorganisms.
The standard testing services we provide are outlined below.
Total viable bacterial and fungal counts
Total bacterial and fungal levels are assessed by growth on a range of solid culture media incubated under appropriate conditions. Total levels of viable bacteria and fungi are assessed and predominant culturable species are determined. Assessment can be carried out on air samples, wipe samples and bulk samples, including:
- metal working fluids
- water
- soil
Most sample types can be considered for analysis.
Anthrax testing
Anthrax has historically been associated with the handling of skins from infected animals. If an individual breathes in the spores they can develop lesions within their lungs, causing flu-like symptoms and breathing difficulties that may cause death within days if left untreated.
Our scientists use a combination of live culture and molecular analysis methods to detect B. anthracis. We have extensive experience of analysing lath and plaster samples from old buildings and soil samples from potentially contaminated land.
Presence or absence of Bacillus anthracis, the causative agent of anthrax, is assessed using DNA and culture-based methods. Microbiological work is performed within HSE's Microbiological Containment Level 3 facility. Analysis for B. anthracis can be carried out on air samples, wipe samples and bulk materials, including soil and plaster. For bulk samples, approximately 10g sample is routinely used in the test, although smaller samples can be analysed. Our Sample Registration Team will provide appropriate containers for transportation of samples.
If you would like to send samples to us for analysis please get in touch. We will supply sample pots and appropriate packaging so the samples can be sent safely through the mail.
It is important that samples that may contain anthrax are packaged safely and securely.
HSE will supply sample kits with the necessary containers and packaging to be used for transportation to HSE's Science and Research Centre in Buxton. These kits are available on request and are free.
Please pre-book anthrax testing with us to avoid delays. We may have periods where testing is postponed.
Endotoxin
Endotoxin is a component of the cell envelope of all Gram-negative bacteria and is commonly found in the environment. Endotoxin can cause ill-health via inhalation in those repeatedly exposed to raised levels, irrespective of whether the bacteria are live, dead, whole or fragmented, and there are many working environments where high levels of endotoxin are believed to cause respiratory symptoms.
HSE uses a widely accepted, validated and automated quantitative kinetic assay system for endotoxin analysis. Exposure monitoring can be performed from static air and personal air samples (providing information about specific task-related exposures), wipe samples and bulk samples (such as liquid, organic material.). HSE can advise on or assist with air sampling methods and can provide trained field scientists to obtain samples if required.
Bespoke services
In addition to the services listed above, we are able to carry out a range of bespoke testing services for the molecular identification of bacteria by Polymerase Chain Reaction (PCR), with qualitative tests available for a wide range of fungi and bacteria.
The HSE Microbiology Team has a wide range of experience in bacteriology, mycology and virology and access to extensive facilities, including a 34m3 controlled atmosphere chamber that can be used for controlled release of bioaerosols or microbiological decontamination studies that require the use of hazardous chemicals. We are able to carry out bespoke project work tailored to customer requirements.
Desk-based information gathering
The HSE Microbiology Team has experience in the area of information gathering and literature reviews and is able to carry out literature searching and data gathering to customer requirements.
