Parasites as fountains of youth: Study finds infected ants live much longer

Parasitic infections are usually harmful to their hosts, but there are some exceptions. According to the results of a multi-year scientific study, ants of the species Temnothorax nylanderi show exceptionally high survival rates when infected with a tapeworm. The lifespan of the infected ants is significantly prolonged. According to our observations, such workers have a survival rate similar to that of queens, said Professor Susanne Foitzik of Johannes Gutenberg University Mainz (JGU), leader of the study. Queens of this species can live for up to 20 years, while female workers rarely reach the age of two. Among possible explana

Ant responses to social isolation resemble those of humans

Credit: photo/©: Susanne Foitzik, JGU Ants react to social isolation in a similar way as do humans and other social mammals. A study by an Israeli-German research team has revealed alterations to the social and hygienic behavior of ants that had been isolated from their group. The research team was particularly surprised by the fact that immune and stress genes were downregulated in the brains of the isolated ants. This makes the immune system less efficient, a phenomenon that is also apparent in socially isolating humans - notably at present during the COVID-19 crisis, said Professor Susanne Foitzik, who headed up the study at Johannes Gutenberg University Mainz (JGU). The study on a species of ant native to Germany has recently been published in
