But only 4% of known parasites can infect humans, and the majority actually serve critical ecological roles, like regulating wildlife that might otherwise balloon in population size and become pests.

Evidence from a population-representative birth cohort. Although the mechanism of achieving higher sexual attractiveness in the infected individuals is yet to be discovered, there are independent findings that T. gondii increases the level of testosterone in male rats (Lim et al., 2013). Moreover, humans (along with e.g., dogs or rats) are extremely capable of odor detection, they are able to detect odorants at concentrations as low as three droplets in an Olympic-size swimming pool (Yeshurun and Sobel, 2010). 11, 547553. Wood is the lead author on one study in the collection that finds the responses of parasites to environmental change are likely to be complex, and that a changing world probably will see both outbreaks of some parasites and a total loss of other parasite species.

The microbiota (microbes living inside us and on us) then systematically affect development and function of organs, including the brain (the gut-brain axis is a bidirectional communication channel via neural, endocrine, and immune pathways; Mayer et al., 2014). But by doing so, C. australis also has a cascading effect on the rest of the ecosystem as the mudflat become covered with stranded bivalves.

The studies also identified correlation between toxoplasmosis and several mental illnesses (whose occurrence is connected with the aforementioned hormones and neurotransmitters): schizophrenia (Torrey et al., 2012), autism (Prandota, 2010), mood disorders (Pearce et al., 2012) and suicidal inclination (Ling et al., 2011); but see Sugden et al. This blood parasite originally arrived at Hawaii in the blood streams of introduced birds such as canaries. (2017) summarize the existing evidence: [H]uman odorants become a medium by means of which information about dynamic states (e.g., emotions) and enduring characteristics (e.g., age, gender, individuality, personality) can be transferred from a sender to a receiver. The possible applicability of these findings in organization and labor economics or human resources management studies is clear. (2016). Psychol.

Parasites are an incredibly diverse group of species, but as a society, we do not recognize this biological diversity as valuable, said Wood, an assistant professor in the UW School of Aquatic and Fishery Sciences.
