Available online 31 August 2019 Author(s): Jin-Lei Wang, Hany M. Elsheikha, Ting-Ting Li, Jun-Jun He, Meng-Jie Bai, Qin-Li Liang, Xing-Quan Zhu, Wei CongABSTRACTThe obligate intracellular parasite Toxoplasma gondii can infect nearly all warm-blooded animals including humans.

Cyclospora cayetanensis is a coccidian parasite that has been associated with foodborne outbreaks of gastrointestinal illnesses. Raspberries have been implicated as vehicle of infection in some of these outbreaks. Most of the molecular techniques used for the detection of parasites commonly use the 18s rRNA as a target gene, which is highly conserved. The conserved nature of 18s rRNA gene among...

Abstract The issue of whether market fish can be involved in the transmission of Toxoplasma gondii in the marine environment is highly debated since toxoplasmosis has been diagnosed frequently in cetaceans stranded along the Mediterranean coastlines in recent times. To support the hypothesis that fishes can harbour and effectively transmit the parasite to top‐of‐the‐food‐chain marine organisms...

Neospora caninum is a protozoan parasite closely related to Toxoplasma gondii. Neosporosis caused by N. caninum is considered one of the main causes of abortion in cattle and nervous-system dysfunction in dogs, and identification of the virulence factors of this parasite is important for the development of control measures. Here, we used a luciferase reporter assay to screen the dense granule...

Abstract Toxoplasmosis is one of the most common meat-borne parasitic infections worldwide. Consumption of raw or undercooked meat which contains Toxoplasma gondii tissue cysts is an important route of human infection. In this study, we investigate the serological and molecular prevalence of T. gondii infection in sheep and goat samples in Kashan, Iran, from 2015 to 2016. Serological (IgG...

Summary Toxoplasma gondii infections cause a large disease burden in the Netherlands, with an estimated health loss of 1,900 Disability Adjusted Life Years and a cost-of-illness estimated at €44 million annually. Infections in humans occur via exposure to oocysts in the environment and after eating undercooked meat containing tissue cysts, leading to asymptomatic or mild symptoms, but potentially...
