Zi-Qi Lin, Soo-Wah Gan, Szu-Yu Tung, Chun-Che Ho, Li-Hsin Su, Chin-Hung Sun Giardia lamblia becomes dormant differentiation into a water-resistant cyst that can infect a new host. Synthesis of three cyst wall proteins (CWPs) is the fundamental feature of this differentiation. Myeloid leukemia factor (MLF) proteins are involved in cell differentiation, and tumorigenesis in mammals, but little is...

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...

In this study, we assessed the prevalence and genetic characteristics of Cryptosporidium in sheep from 10 provinces in China. Fecal samples from 1,035 sheep originating from 16 farms were collected, and 295 (28.5%) were found to be Cryptosporidium positive by nested PCR. Cryptosporidium was detected at all farms, with infection rates between 5.7% and 50.0%. Three Cryptosporidium species were...

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...
