Aim: This study was designed to evaluate the network productions and research collaborations on toxoplasmosis worldwide.

Materials and Methods: A bibliometric research was carried out using the Web of Science (WOS) database. The analysis unit was the original research articles about toxoplasmosis published between 2000 and 2016 (17 years).

Results: Totally, 6,550 articles about toxoplasmosis were indexed in the WOS with the following information: (A) 18,410 researchers played a role in drafting the articles; (B) 33 different countries have contributed in the toxoplasmosis studies; (C) the USA was ranked at the first place with 2,162 publications about toxoplasmosis; and (D) "Dubey JP" was compiled and participated in 401 articles from the USA, as the highest number and main core of publications in the toxoplasmosis network.

Conclusion: The main focus of the toxoplasmosis research activities in the world was article production in the indexed journals in WOS. Hence, it is necessary to strengthen the collaboration networks to improve the quality of articles. Furthermore, the priority would be the identification of institutions with a higher number of research article productions in WOS, to perform toxoplasmosis collaborative original researches according to the strategic roadmap and scientific plan of each country.
