Our lab is interested in intracellular eukaryotic parasites called microsporidia. These parasites are found to infect a broad range of hosts causing devastation and economic losses in several industries. One of them is shrimp aquaculture. Microsporidian Enterocytozoon hepatopenaei (EHP) are found to infect shrimp and the infection results in growth retardation and severe size variation. EHP as well as other microsporidian species possess a unique, harpoon-like infection apparatus called the polar tube. The polar tube is rapidly fired when the parasites are in suitable environments or encounter a host. However, little is known about this firing process in EHP. We aim to understand how EHP gain entry into the shrimp cells, the dynamics of the polar tube firing in this species, as well as how host cells defend against the EHP infection. 

Research Topics:

•  Polar tube firing kinetics of shrimp microsporidian

•  Identification of the physiological conditions for the polar tube firing in the shrimp host 

•  Transcriptomic analysis to elucidate how shrimp respond to microsporidian infection
