Clinical Bacteriology

The bacteriology department tests a wide variety of sample types for bacterial and fungal pathogens. Microbiology results can take a bit longer than more straightforward blood tests, because we have to allow time for the organisms to grow before we can reliably identify them and do further work on them. We test samples from every area of the body to look for evidence of infection, such as sputum samples for diagnosis of chest infections, nail clippings to check for fungal nail infections, faecal samples to find bacterial and parasitic causes of gastroenteritis, cerebrospinal fluid samples to check for meningitis, and pus or tissue samples to investigate the cause of abscesses or other deep-seated infections, to name but a few.

Significant organisms are presumptively identified by their appearance, and the identification is confirmed by a combination of biochemical testing, mass spectrometry and sometimes their appearance under the microscope. The sensitivity of these organisms to any relevant antimicrobials is tested to help direct treatment, or to allow de-escalation of broad spectrum antibiotics to a more targeted approach. In certain samples we use techniques such as microscopy or flow cytometry to look for microscopic elements such as white blood cells, crystals, or parasitic ova and larvae, which are all valuable indicators of infection or other disease in certain samples.

We also invest significant amounts of resources into screening for the so-called “hospital superbugs” MRSA and Clostridium difficile, to help infection control teams to quickly identify infected individuals and put measures in place to prevent its spread.
