Prevalence and genotypes of Enterocytozoon bieneusi in pigs in southern China.

Enterocytozoon bieneusi is one of the most important causative agents of microsporidiosis, causing diarrhoea the symptoms of enteric disease in humans and animals. Although there is some information on the prevalence and genotypes of E. bieneusi in China, there is still a lack of data in pigs in southern China.

Transcriptomic analysis reveals Toxoplasma gondii strain-specific differences in host cell response to dense granule protein GRA15.

Growth and replication of the protozoan parasite Toxoplasma gondii within host cell entail the production of several effector proteins, which the parasite exploits for counteracting the host's immune response. Despite considerable research to define the host signaling pathways manipulated by T. gondii and their effectors, there has been limited progress into understanding how individual members of the dense granule proteins (GRAs) modulate gene expression within host cells.

Identification of two novel host proteins interacting with Toxoplasma gondii 14-3-3 protein by yeast two-hybrid system.

Toxoplasma gondii deploys many effector proteins in order to hijack and manipulate host cell signaling pathways, allowing parasite colonization, subversion of immune responses, and disease progression. T. gondii effector protein 14-3-3 (Tg14-3-3) promotes parasite dissemination inside the body, by enhancing the migratory ability of infected microglia and dendritic cells.

Global miRNA expression profiling of domestic cat livers following acute Toxoplasma gondii infection.

Although microRNAs (miRNAs) play an important role in liver homeostasis, the extent to which they can be altered by Toxoplasma gondii infection is unknown. Here, we utilized small RNA sequencing and bioinformatic analyses to characterize miRNA expression profiles in the liver of domestic cats at 7 days after oral infection with T. gondii (Type II) strain.

[Research Progress on Genetic Diversity in Animal Parasitic Nematodes].

The development of molecular genetic markers for parasitic nematodes has significant implications in fundamental and applied research in Veterinary Parasitology. Knowledge on genetic diversity of nematodes would not only provide a theoretical basis for understanding the spread of drug-resistance alleles, but also have implications in the development of nematode control strategies. This review discusses the applications of molecular genetic markers (RFLP, RAPD, PCR-SSCP, AFLP, SSR and mitochondrial DNA) in research on the genetic diversity of parasitic nematodes.

Molecular characterization of the Haemonchus contortus phosphoinositide-dependent protein kinase-1 gene (Hc-pdk-1).

Background: Phosphoinositide-dependent protein kinase-1 (PDK-1), which functions downstream of phosphoinositide 3-kinase (AGE-1) and activates protein kinases of the AGC family, plays critical roles in regulating biology processes, such as metabolism, growth, development and survival. In the free-living nematode Caenorhabditis elegans, PDK-1 is a key component of the insulin-like signalling pathway, regulating the entry into and exit from dauer (arrested development). Although it is proposed that similar molecular mechanisms control the transition from the free-living to the parasitic stages of nematodes, nothing is known about PDK-1 in Haemonchus contortus, a socioeconomically important gastric nematode of ruminants.

Exploring the role of two interacting phosphoinositide 3-kinases of Haemonchus contortus.

Background: Phosphoinositide 3-kinases (PI3Ks) are relatively conserved and important intracellular lipid kinases involved in signalling and other biological pathways. In the free-living nematode Caenorhabditis elegans, the heterodimeric form of PI3K consists of catalytic (AGE-1) and regulatory (AAP-1) subunits. These subunits are key components of the insulin-like signalling pathway and play roles in the regulation of the entry into and exit from dauer.
