Microbiology

Microbiology studies microorganisms – unicellular and multicellular – and it covers a range of subdisciplines, including mycology, virology, bacteriology and parasitology.

Microbiological tests enable reliable detection of the causes of infections caused by fungi, bacteria, viruses, protozoa and parasites.

Within bacteriological tests, isolation of bacteria from various samples (urine, feces, sputum, swab or secretion) enables the identification of bacteria as possible causes of infection. In this way, it is possible to examine the sensitivity of bacteria to various antibiotics, which is very important in choosing the appropriate treatment.

Virological tests are based on proving the presence of antigens (parts of the viruses themselves) in a sample or proving the presence of specific antibodies, which are produced as part of the body’s immune response to infection with a particular virus.

Parasitological tests include direct parasitological examination of the sample (usually stool-feces) and indirect methods, such as immunodiagnostic tests. Direct parasitological examination reveals the presence of parasites, while indirect methods reveal the presence of antibodies created to a specific parasite in the patient’s serum.

Mycological tests are based on the isolation of pathogenic fungi from various biological materials. Pathogenic fungi can be isolated from faeces, urine, swabs, sputum and skin scrapes, while antibodies to fungi can be isolated from the patient’s serum. Within these tests, the cultivation of fungi and microscopy, which belong to direct methods, as well as enzyme tests, which belong to indirect methods, are performed.

Most microbiological tests require special patient preparation, especially in the case of antibiotic therapy. In that case, it is recommended that the sample not be taken for at least 7 days after the end of the therapy.

Aqualab laboratories perform all necessary microbiological tests. Microbiological diagnostics provided by our laboratories include sampling and sample processing with isolation and identification of pathogens as well as interpretation of results and susceptibility of microorganisms to drugs.
