Plasmodium berghei: physiopathological changes during infections in mice

Area of Science:

• * Immunology and Parasitology
• * Pathophysiology of Infectious Diseases

Background:

• * Malaria, caused by Plasmodium parasites, is a significant global health concern.
• * Understanding the host's physiological response to infection is crucial for developing effective treatments.

Purpose of the Study:

• * To investigate the physiopathological changes in laboratory mice infected with Plasmodium berghei.
• * To characterize the host's response during the acute phase of malaria infection.

Main Methods:

• * Infection of laboratory mice with Plasmodium berghei.
• * Monitoring of haematological parameters, including haematocrit and leucocyte counts.
• * Assessment of physiological changes such as pulmonary oedema and body temperature.

Main Results:

• * Significant reduction in haematocrit and increased levels of parasitized erythrocytes observed.
• * Development of pulmonary oedema, hypothermia, and central nervous system prostaglandin-like substances.
• * Leukocytosis characterized by neutrophilia, lymphocytosis, and monocytosis; no changes in total protein or albumin/globulin ratio.

Conclusions:

• * Plasmodium berghei infection induces a complex array of pathophysiological changes in mice.
• * The observed changes, including CNS inflammation and altered bradykininogen levels, contribute to disease severity.
• * Further research is warranted to explore therapeutic interventions targeting these host responses.
