First evidence of human infection by the kinetoplastid flagellate Dimastigella trypaniformis in a patient with urinary tract infection.
Int J Infect Dis

Molecular Microbiology Laboratory, Department of Pathology, Molecular and Cell-Based Medicine, Icahn School of Medicine at Mount Sinai, New York, NY, 10029, USA. Electronic address:
We present a case of an 88-year-old man with symptoms consistent with a urinary tract infection, whose diagnostic workup uncovered a previously unrecognized motile flagellated protozoan. Molecular identification confirmed the organism as Dimastigella trypaniformis, a free-living kinetoplastid from the Rhynchomonadidae family. Known only from soil samples in Scotland and termite gut contents in Australia and Germany, Dimastigella trypaniformis has not been previously reported to infect vertebrate hosts.

State Key Laboratory Incubation Base for Green Processing of Chemical Engineering, School of Chemistry and Chemical Engineering, Shihezi University, Shihezi 832003, China.
Objectives: Polysaccharides from are known to have several bioactive effects. Previous studies have found that low-molecular-weight polysaccharide (GP1) is degraded by and promotes the production of beneficial bacteria and metabolites, which improves immune disorder and intestinal injury, and then enhances the body's immune regulation ability. However, the immune regulation effect of GP1 on a healthy body has not been studied.

January 2025
Heilongjiang Provincial Key Laboratory of Corn Deep Processing Theory and Technology, College of Food and Bioengineering, Qiqihar University, Qiqihar 161006, China.
Objectives: This study aimed to clarify the effect of lactic acid bacteria-fermented corn protein hydrolysate (FCH) on fatigue in mice and explore the connection between fatigue-related indicators and intestinal microbial flora.
Methods: The fatigue model of mice was constructed by exercise endurance experiment. The anti-fatigue level of FCH was evaluated by measuring physiological and biochemical indexes in mouse serum, liver and skeletal muscle.
