[Extracerebral infections of Acanthamoeba spp. in mice]
Abstract:
A variety of Acanthamoeba spp. pathogenic strains were isolated from water pools in the area of Poznań. In many cases amoebae invaded in mice, beside central nervous system (CNS) also lungs, kidney, heart, liver, diaphragm and eyeballs, causing significant changes in these organs. The presence of amoebae outside of CNS was found mainly in the early period of infection. Amoebae isolated from different organs of dead animals did not exhibit any specificity in relation to the organs in following infections.
Insights
Pathogenic Acanthamoeba species from Poznań water pools infected mice, affecting multiple organs including the central nervous system (CNS). Early infection showed amoebae spread beyond the CNS, with no organ specificity observed in later stages.
Area of Science:
- Microbiology
- Parasitology
- Infectious Diseases
Context:
- Acanthamoeba species are ubiquitous protozoa found in various water sources.
- Pathogenic strains pose a risk of infection in both humans and animals.
- Understanding Acanthamoeba dissemination is crucial for disease control.
Purpose:
- To investigate the pathogenicity and organ distribution of Acanthamoeba strains isolated from water pools in Poznań.
- To determine the extent of invasion and pathological changes caused by Acanthamoeba in a murine model.
- To analyze the temporal dynamics and organ specificity of Acanthamoeba infection.
Summary:
- Pathogenic Acanthamoeba strains were isolated from Poznań water pools.
- Infection in mice led to invasion of the central nervous system (CNS) and other organs like lungs, kidneys, heart, liver, diaphragm, and eyeballs, causing significant pathological changes.
- Acanthamoeba presence outside the CNS was primarily observed during the early infection period.
- No specific organ tropism was identified for Acanthamoeba isolated from different organs in subsequent infections.
Impact:
- Highlights the potential public health risk associated with Acanthamoeba in recreational water environments.
- Provides insights into the systemic nature of Acanthamoeba infections beyond the CNS.
- Informs future research on Acanthamoeba pathogenesis and treatment strategies.
