spores displaying GRA12 induce immunity against acute toxoplasmosis.

Background: () is a widely prevalent intracellular parasite that infects almost all warm-blooded animals and causes serious public health problems. The drugs currently used to treat toxoplasmosis have the disadvantage of being toxic and prone to the development of resistance, and the only licensed vaccine entails a risk of virulence restoration. The development of a safe and effective vaccine against is urgently needed.

Molecular Detection and Genotyping of from Pigs for Human Consumption in Zhejiang and Jiangsu Provinces, Eastern China.

infections are common in humans and animals worldwide. Ingestion of raw or undercooked meat containing tissue cysts of is one major source of transmission of this parasite. It is important to guarantee the meat quality of China since our pork industry produces about half of the world's pork.

[Pregnancy Outcomes and Prognosis of Fetal Ventriculomegaly: A Retrospective Cohort Study].

Objective: To evaluate the pregnancy outcomes and neurodevelopment prognosis of subjects prenatally diagnosed with fetal ventriculomegaly (VM).

Methods: All the subjects with VM diagnosed by ultrasound and were admitted and treated at West China Second Hospital, Sichuan University between March 2011 and September 2020 were retrospectively enrolled for a chohort study, while non-VM subjects of the same period were selected with a random number table to form the control group. Pregnancy outcomes of the two groups were compared, and the fetuses of both groups were followed up after birth for further assessment and comparison of their neurodevelopmental prognosis.

Characterization of Starch in Germplasms throughout Fruit Development.

Pumpkins (; Cucurbitaceae) are the rich source of nutrients and valued for their biologically active substances to be used for the treatment of several diseases. The contents, composition, and conformation of starch are the significant quality traits of . Two germplasms were targeted for analysis regarding the taste difference.

Metabolic and transcriptomic analysis of two Cucurbita moschata germplasms throughout fruit development.

Background: Pumpkins (Cucurbita moschata; Cucurbitaceae) are valued for their fruits and seeds and are rich in nutrients. Carotenoids and sugar contents, as main feature of pumpkin pulp, are used to determine the fruit quality.

Results: Two pumpkin germplasms, CMO-X and CMO-E, were analyzed regarding the essential quality traits such as dry weight, soluble solids, organic acids, carotenoids and sugar contents.

A high-density linkage map and QTL mapping of fruit-related traits in pumpkin (Cucurbita moschata Duch.).

Pumpkin (Cucurbita moschata) is an economically worldwide crop. Few quantitative trait loci (QTLs) were reported previously due to the lack of genomic and genetic resources. In this study, a high-density linkage map of C.

Construction of a lentiviral T/A vector for direct analysis of PCR-amplified promoters.

The promoter plays an important role in the regulation of gene expression. To analyze a promoter's activity, we developed a novel lentiviral T/A vector that contains two reporter genes, a luciferase (Luc2) gene and a green fluorescent protein (Venus) gene, that are linked via an internal ribosome entry site (IRES2). To test the performance of this vector, phosphoglycerate kinase-1 (PGK) and elongation factor-1α (EF1α) promoters were amplified by PCR and inserted into this lentiviral T/A vector using T4 DNA ligase, yielding two promoter-reporter vectors: pLent-T-PGK and pLent-T-EF1α.

Molecular cloning, sequencing, and expression of the outer membrane protein P2 gene of Haemophilus parasuis.

Haemophilus parasuis is the etiological agent of Glässer's disease characterized by fibrinous polyserositis, polyarthritis, and meningitis in young pigs. But it is difficult to develop universal serological diagnostic tools and effective vaccines against this disease because of the serovar diversity of the isolates. In this study, enterobacterial repetitive intergenic consensus-polymerase chain reaction, were performed to investigate the gene profile of 111 isolates of H.

Genotyping of Haemophilus parasuis from diseased pigs in China and prevalence of two coexisting virus pathogens.

From December 2003 to July 2006, a total of 131 (28.4%) Haemophilus parasuis strains were isolated from 462 cases examined in our diagnostic laboratory. These strains were isolated from clinically diseased pigs, and 50 of them along with 15 reference strains of all known serovars were subjected to PCR-FRLP (restriction fragment length polymorphism) analysis by tbpA gene.
