However, there is no data about their occurrence in the air or about airborne transmission of these infections. In the present paper, we report on the identification of<jats:italic>T. gondii<\/jats:italic>using rapid molecular detection methods, supported by microscopic analysis, in environmental air samples. A total of 71 samples were collected, using gelatine filters, from kitchen gardens, recreational areas and sandpits located in northern and north-eastern Poland. Material recovered from the filters was analysed using real-time PCR and loop-mediated isothermal assays targeting the<jats:italic>T. gondii<\/jats:italic>B1 gene.<jats:italic>Toxoplasma gondii<\/jats:italic>DNA was found in two samples, as confirmed by both molecular assays. Genotyping at the SAG2 locus showed<jats:italic>Toxoplasma<\/jats:italic>SAG2 type I. Moreover, the presence of<jats:italic>T. gondii<\/jats:italic>oocysts was confirmed in one of the positive samples with the use of microscopy. The results showed that<jats:italic>T. gondii<\/jats:italic>may be present in environmental air samples and that respiratory tract infections may play a role in the high prevalence of toxoplasmosis in humans and animals. To the best of our knowledge, this is the first epidemiological evidence that oro-fecal and foodborne toxoplasmosis may be traceable to an airborne respiratory origin and that this may represent a new, previously unknown transmission route for this disease.<\/jats:p>","DOI":"10.1017\/s0031182017001172","type":"journal-article","created":{"date-parts":[[2017,7,12]],"date-time":"2017-07-12T07:21:59Z","timestamp":1499844119000},"page":"1791-1801","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":19,"title":["The
