Toxoplasmosis in Greater Victoria

Area of Science:

• Medical Microbiology
• Epidemiology
• Immunology

Background:

• Toxoplasma gondii is a ubiquitous parasite with significant public health implications.
• Seroprevalence studies are crucial for understanding the transmission dynamics and burden of toxoplasmosis in diverse populations.

Purpose of the Study:

• To determine the seroprevalence of Toxoplasma gondii antibodies in Greater Victoria.
• To identify recent Toxoplasma gondii infections, particularly in women of childbearing age.

Main Methods:

• A cross-sectional serological survey was conducted on 596 inhabitants of Greater Victoria.
• Methylene blue dye test was used to detect antibodies to T. gondii.
• Indirect fluorescent antibody test (IgM) was employed to identify recent infections.

Main Results:

• Overall, 28% of participants had antibodies to T. gondii (titre ≥ 1:8).
• Recent T. gondii infection was detected in 3% of the total cohort.
• Among women who recently gave birth, 25% had antibodies, with a higher prevalence (37%) in the 31-35 year age group.

Conclusions:

• Toxoplasma gondii infection is prevalent in the Greater Victoria population.
• A notable proportion of recent infections were identified, highlighting the need for continued surveillance.
• Specific demographic groups, such as women of reproductive age, may represent a higher-risk population for T. gondii exposure.
