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 ...

Parasites are a group of eukaryotic organisms that may be free-living or form a symbiotic or parasitic relationship with the hosts. Consisting of over 800,000 recognized species, parasites may be unicellular (Protozoa) or multicellular (helminths and arthropods). The association of parasites with human population started long before the emergence of civilization. Parasitic zoonotic diseases are...

Parasitic diseases constitute major public health challenges worldwide, especially in developing countries. It is estimated that more than one billion people worldwide are infected by parasites presenting with different disease conditions. The routine laboratory diagnosis of parasitic infections in most tropical countries involves conventional methods, such as optical microscopy, used for the m...

Epidemic Giardia lamblia infection has usually been associated with contaminated water. In this paper, five proved and one presumed case of G. lamblia infection among homosexual men are reported. The sequential onset of their clinical illnesses and their sexual interrelationships suggest that this outbreak could have been caused by the direct faecal-oral transmission of G. lamblia. Other parasi...

Emerging zoonoses have been defined as zoonoses that are newly recognised or newly evolved, or that have occurred previously but show an increase in incidence or expansion in geographical, host or vector range. Among parasitic zoonoses, protozoa are particularly likely to emerge. Control and prevention of emerging parasitic zoonoses are complex tasks that require an integrative and multidiscipl...

Parasites cause some of the most devastating and prevalent diseases in humans and animals. Moreover, parasitic infections increase mortality rates of other serious non-parasitic infections caused by pathogens such as HIV-1. The impact of parasitic diseases in both industrialised and developing countries is further exacerbated by the resistance of some parasites to anti-parasitic drugs and the a...

Climate change is an emerging global issue. It is expected to have significant impacts both in Egypt and around the world. Thus, the country is in need for taking action to prepare for the unavoidable effects of climate change, including the increase in water stress, the rise in sea level, and the rapidly increasing gap between the limited water availability and the escalating demand for water ...
