Microbiological pond profile

The bacteria in the water always reflect the quality of the body of water. They are not automatically enemies; they can also be essential helpers. What matters is a stable balance.

All information at a glance

Microbiological water analysis (detection of the total viable count and indicator organisms such as enterobacteria, pseudomonads and aeromonads) goes a decisive step further than physical/chemical water analysis. It shows how biologically stable the system actually is and which infectious risks are specifically present.

500 ml of the water to be tested

The sample container—e.g., a plastic (PET) water bottle is well suited—should not be pre-cleaned with dishwashing detergent. Before sampling, it is recommended to rinse the container several times with the water sample to be tested. Submerge the container completely under water with the opening facing down and turn it until all air has escaped. Close the container under water.

Take the water sample at a time that avoids unnecessary standing times; the same applies to shipping (express shipping)!

The less time there is between sampling and analysis, the more accurately the result reflects the current condition of the water.

3–4 days from receipt of the sample

In accordance with European standards, the microorganisms are cultured for 3 days on appropriate selective media and then counted.

The microbial load in the water is an important microbiological criterion for water quality.

Total viable count
Determining the colony count detects viable microorganisms that develop from the water sample to be tested using the so-called pour plate method at a defined incubation temperature within a specified period under aerobic conditions.

The colony count is used as an indicator of organic pollution of the body of water. In line with the content of organic substances that can be broken down by bacteria, the colony count of saprophytic microorganisms increases. The colony count therefore has a direct relationship to water quality.

Detection of indicator organisms (enterobacteria, aeromonads, pseudomonads)

Indicator organisms are microorganisms whose presence—especially the frequency with which they occur—allows conclusions to be drawn about water quality and contamination.

Enterobacteria
The large group of enterobacteria is part of the natural intestinal flora that is excreted into the water by fish. Many members of this bacterial group are of great medical importance, as they can cause or transmit a wide range of diseases. In immunocompromised animals, otherwise “harmless” enterobacteria can cause so-called opportunistic infections; others are highly aggressive and cause serious diseases that can lead to the death of the host organism.

Aeromonads/Pseudomonads
Aeromonads and pseudomonads are naturally occurring environmental microorganisms that are always present in small quantities in all inland waters. High temperatures combined with a high nutrient supply promote explosive bacterial growth. Mass proliferation leads to an increased incidence of wound infections, as the infection pressure in the water rises. Patchy skin reddening, detachment of scales and severe inflammation are the result.

Test parameters

  • Total viable count – indicator of organic pollution of the body of water = infection pressure

  • Pseudomonads cause, among other things, inflammation, ulceration, fin rot, frayed or disintegrating fin edges

  • Aeromonads cause, among other things, skin hemorrhages, ulcers, raised scales, fin rot and tissue breakdown

  • Enterobacteria cause non-specific general symptoms: apathy, loss of appetite, isolation, abdominal distension, mucous feces
