Abstract

Purpose of Review

Cyst-forming heteroxenous Apicomplexan parasites are important parasites of both humans and animals. Here, we discuss currently available evidence of possible sexual transmission of these parasites.

Recent Findings

Seven genera of Apicomplexans are known to have multi-mode, multi-host life cycles. Prior studies have examined the possibility of sexual transmission in three of these genera: Besnoitia, Neospora, and Toxoplasma. There is extensive evidence of sexual transmission of Toxoplasma in several nonhuman animals. However, evidence for the sexual transmission in humans remains equivocal. Sexual transmission of Besnoitia and Neospora has remained contentious given the small number of inconclusive reports.

Summary

It is important to determine if Toxoplasma is a sexually transmitted infection in humans, due to the clinical implications of Toxoplasma in immune-deficient humans and its potential effects on pregnancy. Additionally, this class of parasites can serve as useful perturbation systems to understand the development of virulence and breach of the blood-testes barrier.

This paper provides a comprehensive review of the biology and regulation of the blood-testes barrier. Additionally, the author highlights the fact that although research in this area has been ongoing for approximately five decades, so much remains unknown about the blood-testes barrier and goes further to suggest multiple new avenues of investigation that will enhance our understanding of the BTB. This is of immense importance because sexual transmission suggests the parasite’s ability to breach the blood-testis barrier. Thus, understanding the regulation of the BTB is crucial to understanding how some parasites are able to breach this otherwise stringent blood-tissue barrier.

The case of Toxoplasma gondii. Proc R Soc London Ser B. Biol Sci. 2013;280(1765). doi:https://doi.org/10.1098/rspb.2013.1143. This paper provides an excellent discussion on the opposing nature of selection pressures that drive trophic versus sexual selection. The authors argue that in a parasite such as Toxoplasma , that is transmitted via both sexual and trophic routes, there will be a trade-off in these selection pressures that is likely dependent on prevailing environmental conditions. This suggests that the loss of aversion to predator phenotype in Toxoplasma rodents may be blunted depending on prevailing environmental conditions and as a result, selection pressures. • Lélu M, Langlais M, Poulle M-L, Gilot-Fromont E, Gandon S.
