First molecular identification of Vorticella sp. from freshwater shrimps in Tainan, Taiwan

International Journal for Parasitology: Parasites and Wildlife, 2018
Freshwater shrimps are the most common crustaceans kept in an aquarium. This study was a survey seeking parasites infecting cultured freshwater atyid shrimps at aquarium stores in Tainan, Taiwan.

Vorticella: A Protozoan for Bio-Inspired Engineering

Micromachines, 2016
In this review, we introduce Vorticella as a model biological micromachine for microscale engineering systems. Vorticella has two motile organelles: the oral cilia of the zooid and the contractile spasmoneme in the stalk. The oral cilia beat periodically,

Ciliated Epibionts Modify the Cardiac Stress Reaction to Perceived Predation in Daphnia [PDF]

Microorganisms
When animals perceive an acute stressor like a predator, they typically undergo a suite of physiological changes that function to improve survival during the encounter, such as elevation in cardiac output, to supply more energy to muscles.

Microvalve actuated by Vorticella: self-oscillating valve and improvement measures to calcium-responsive valve

Mechanical Engineering Journal, 2021
Living machines have microactuators and are suitable for further miniaturization of microsystems, and their potential as autonomous microrobots has been investigated.

Ectoparasite infestation and Vibrio alginolyticus bacterial infection in super-intensive ponds with high ammonia levels of Penaeus vannamei [PDF]

E3S Web of Conferences, 2021
Disruption to fish and shrimp farming can be caused by poor water quality or invading pathogens. This study aims to determine the degree of ectoparasite infestation and Vibrio alginolyticus bacterial infection in super-intensive ponds.
