Does not specify if this was noted that in both women and men.

IIRC, T. gondii infection in humans has different effects dependent on sex of human - if I do recall right, it makes men more "risk taky" but women more "friendly and eager to please". But do please check me on that.

The effect on risk-taking behaviour has been known for along time of course.

Also slows reaction time! (if you are a mouse, means you get caught by cats, which is good for the lifecycle of T. gondii!)

aha, the wolf study DOES look at females.

"Similarly, infected females had 25 percent chance of leaving their pack within 30 months, compared with 48 months for those who weren't infected."

possible mechanisms...

dopamine: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5579228/
also testosterone: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2526142/

I can imagine "dopamine hits" varying in humans dependent on T levels and social stuff...

"Our group sought to determine the global status of T. gondii infection and to evaluate any continental and geographical trends by systematically examining the currently available epidemiological data on the prevalence of T. gondii infection. A comprehensive literature search was conducted from 10 electronic databases (Google Scholar, Science Direct, Embase, PubMed, PLOS ONE, Web of Knowledge, SciELO, MyAIS, Free Medical Journals, and Scopus) without date or language restrictions. Specific medical subject heading terms were used to search for human T. gondii seroprevalence studies that recruited subjects from general apparently healthy populations. The data were collated and analysed for both continental and global trends.

The search identified 152 published studies that examined a total of 648,010 subjects. From these, 166,255 were seropositive for T. gondii infection indicating an average global seroprevalence rate of 25.7% (95% CI: 25.6 - 25.8%).

The overall range of seroprevalence was determined to be 0.5 - 87.7%.

African countries had the highest average seroprevalence rate of 61.4%, followed by
Oceania with 38.5%,
South America with 31.2%,
Europe with 29.6%,
USA/Canada with 17.5%, and
Asia with 16.4%.

Numerous environmental and human factors affect the differences in T. gondii seroprevalence rates observed between the various countries and continents. Monitoring the source and transmission may assist public health authorities to clarify the risk factors involved, as well as focus on implementing optimal state-specific health policies targeting T. gondii transmission control."

The regional figures surprise me. With their supposed support for/ reliance upon entrepreneurship I am surprised to see Asia and the US/Canada as the least infected.

yeah, that was my thought too, and partly why I hunted out the stats...

Should we ask all our parliamentary candidates to take a Toxoplasma Gondii test ?
