Abstract:

Background Protozoan parasitic diseases are endemic in many countries worldwide especially in developing countries, where infertility is a major burden. These infections can cause diminished or absent ability to conceive (infertility) due to impairment in male and female reproductive systems. MaterialsAndMethods Medline, PubMed, Scopus, Google scholar manuscripts were used to identify the most relevant studies on protozoan parasitic infections and their implications in human and model animal infertility. Results Literature described that some of the protozoan parasites such as Trichomonas vaginalis may causes deformities of genital tract, tubal inflammation and effects on semen quality. Toxopalasma gondii, plasmodium spp. and Trypanosoma brucei spp. cause damage in the pituitary gland, hormonal disorders and decrease semen quality. Trypanosoma cruzi inhibits cell division in embryos and impair normal implantation and development of placenta. Entamoeba histolytica infection can cause pelvic pain, salpingitis, Tubo-ovarian abscess and genital ulcers. Cutaneous and Visceral leishmaniasis causes genital lesion, testicular amyloidosis, inflammation of epididymis, prostatitis and sperm abnormality in human and animals. Conclusion Findings of this review indicate that protozoan parasitic infections may be an important cause of infertility. According to the widespread prevalence of parasitic protozoa diseases in worldwide we recommend further studies to better understand the relationship between these infections and infertility as well as examination of both partners in treatment of infertility.

Cancer in the parasitic protozoans Trypanosoma brucei and Toxoplasma gondii.

Cancer is a general name for more than 100 malignant diseases. It is postulated that all cancers start from a single abnormal cell that grows out of control. Untreated cancers can cause serious consequences and deaths. Great progress has been made in cancer research that has significantly improved our knowledge and understanding of the nature and mechanisms of the disease, but the origins of ca...

Methods for parasitic protozoans detection in the environmental samples.

The environmental route of transmission of many parasitic protozoa and their potential for producing large numbers of transmissive stages constitute persistent threats to public and veterinary health. Conventional and new immunological and molecular methods enable to assess the occurrence, prevalence, levels and sources of waterborne protozoa. Concentration, purification, and detection are the ...

Genetic resistance to parasitic infection.

The ability of animals to resist infections with parasites is genetically determined and therefore variable between individuals or breeds of a given host species. Such variation may involve innate (non-immunological) and acquired (immunologically mediated) resistance mechanisms, and is determined by both major histocompatibility complex (MHC)-linked and non-MHC genes. Resistance is inherited as...
