Stoll Method

The Stoll method is a method for diagnosing helminth infections proposed by the American parasitologist Norman Stoll (1892-1959).

The essence of the method is to wash feces through a sieve and then microscopy the sediment to detect helminth eggs. This makes it possible to concentrate parasite eggs and thereby increases the sensitivity of the analysis.

The Stoll method was widely used to diagnose helminth infections in the first half of the 20th century. It allows you to identify the eggs of such parasites as roundworms, whipworms, pinworms, dwarf tapeworms, etc.

However, this method has now been largely replaced by more modern laboratory methods such as enzyme immunoassay. However, in some cases the Stoll method can still be used, especially in conditions of limited laboratory equipment.

The problem of combating parasites, as well as their study, occupy an important place in the history of medicine. Many scientists have dedicated their lives to finding new methods of treating and diagnosing parasites, and one of them is Stoll.

Born on December 13, 1862 in Germany, Robert Richard Stoll was a famous parasitologist and bacteriologist. He received his doctorate for his work in antibiotics and microbiology, but soon switched to researching parasite-related infectious diseases.

Stoll was interested not only in parasitology, but also in the general anatomy and physiology of organisms. He conducted various experiments aimed at determining the pathogenesis of parasitic infections and identifying factors contributing to the development of the disease in humans. He also studied the development and consequences of fungal infections in plants and animals.

His most famous scientific achievements are related to the study of three diseases: trypanosomiasis, malaria and leishmaniasis. All three diseases were common in different regions of the world, especially in Africa and South America, and had serious consequences for the health and even lives of people. Stoll developed new treatments that were successfully used to treat these diseases for several decades. However, the most important contribution of his work was the development of the devastation method (invasive analysis), a method for examining the blood of infected animals in order to determine the course of the infectious process and its effectiveness.

In his work, Stoll was not limited to just studying one disease. He used new research methods, developed by himself, to study different types of parasites. As a result of his research, he discovered a new species of malarial plasmodium, which was later named P.R. in his honor. Stolleria plasmodium.

One of the most famous scientific methods developed by Stoll is the so-called “Stoll method” - a method of detecting parasites in tissues or lymph. This method used azidine preparations to detect the presence of parasitic infection in infected tissues. Today, this method is the standard diagnostic method for detecting parasites in patients, after which doctors can determine what types of infections are occurring and what measures should be taken. The Stoll method is still used today.
