Streptobacillus Petersena-Ducrea

Streptobacillus Petersen-Ducray: description and features

Petersen-Ducray streptobacillus (Streptobacillus moniliformis) is a gram-negative bacterium that is the causative agent of a number of diseases in humans and animals. This bacterium was first described in 1915 by Danish microbiologists Carl Petersen and André Ducray, who discovered it in rats in Paris.

Streptobacillus Petersen-Ducray has a bacillus shape, but is curvilinear or spiral. It is a very small bacterium, measuring 0.2 to 0.5 µm in diameter and 1 to 3 µm in length. It does not form spores, but can survive in the environment for several months.

Streptobacillus Petersen-Ducray lives in the intestines of rats and can also infect other rodents, such as mice and hamsters. A person can become infected with this bacterium from the bite of an infected rat or other infected rodent. Symptoms of the disease caused by this bacterium may include fever, joint pain, skin rash, and other symptoms that may be related to the specific form of the disease.

Streptobacillus Petersen-Ducray is an important object of study in medicine and microbiology. Its use in the laboratory helps researchers study disease mechanisms and develop new diagnostic and treatment methods. An important advance in the study of this bacterium has been the development of antibiotic treatment, which can successfully combat most forms of disease caused by Streptobacillus Petersen-Ducray.

In conclusion, Streptobacillus Petersen-Ducray is an important object of study in medicine, which causes a number of dangerous diseases in humans and animals. It was first described more than 100 years ago, but remains the subject of active research. Developed methods of treatment and prevention help to successfully fight this bacterium and prevent its spread.



Streptobacillus is a species of bacteria of the genus Salmonella. Most often they live in the human digestive tract. Other names for this microorganism are staphylococcus, Haffke bacterium or Streders-Ducrey bacillus. Streptobacteria have many properties, including the ability to survive in the external environment and contribute to the development of various diseases.
