How Do You Spell BAERMANN APPARATUS?

Pronunciation: [bˈe͡əman ˌapəɹˈe͡ɪtəs] (IPA)

The Baermann apparatus is a laboratory tool used to isolate nematode parasites from soil, sediment, and plant debris. The correct spelling of this word in IPA phonetic transcription is /ˈbaɛrmən əˈpærətʌs/. This is because the word is named after German zoologist Karl Baermann and the second syllable is pronounced with a short "e" sound followed by a stress on the third. The final syllable is pronounced with a schwa sound followed by a stress on the second syllable. The Baermann apparatus is widely used in veterinary and medical fields for accurate diagnosis of nematode infections.

BAERMANN APPARATUS Meaning and Definition

1. The Baermann apparatus is a specialized laboratory equipment used in parasitology and entomology to isolate and collect highly motile organisms such as nematodes, larvae, or protozoa from a given sample, primarily soil or sediment.

   The Baermann apparatus consists of a simple setup comprising a funnel with a fine mesh screen attached at its narrow end, a flask or beaker containing water, and a long glass tube or pipette connected to the lower part of the funnel. The sample, typically moistened soil or sediment, is placed on top of the funnel, and warm water is added into the flask or beaker.

   As the water in the lower container is warmed, it creates a temperature gradient within the apparatus. This temperature gradient causes the motile organisms within the sample to move downwards seeking a favorable environment or swimming against gravity. The force of gravity and the fine mesh screen prevent the organisms from passing through the mesh and into the flask or beaker, therefore, causing them to accumulate in the lower part of the glass tube or pipette.

   Once the desired concentration of organisms is collected at the bottom of the apparatus, the glass tube or pipette can be removed and the organisms can be further examined or studied under a microscope. This technique is beneficial for separating and studying motile organisms that may be present in low abundances or hidden in complex samples like soils, ultimately aiding in the identification and understanding of various species.

   Overall, the Baermann apparatus provides an efficient and simple method for isolating and collecting highly motile organisms, making it a valuable tool in the field of parasitology and entomology research.

Etymology of BAERMANN APPARATUS

The term "Baermann apparatus" is named after the German zoologist Rudolf Baermann. Baermann was a professor of zoology at the University of Berlin and is well-known for his contributions to the field of parasitology.

The Baermann apparatus is a device used to isolate and collect certain nematode parasites that are present in soil or water samples. It consists of a funnel attached to a container, with a filter paper or cloth placed at the bottom. The sample is placed in the funnel and water is gently poured over it. The nematodes in the sample move away from the dry environment and gravity helps them to migrate downward through the filter paper. They are then collected at the bottom of the apparatus for further examination.

Baermann developed this apparatus in the early 20th century as a simple and effective method to detect and study nematodes in various environmental samples.

Plural form of BAERMANN APPARATUS is BAERMANN APPARATUS OR BAERMANN APPARATUSES
