Klebsiella pneumoniae: A pathogenic bacteria transmitted throughHirudo nipponiathat may cause illness in humans

Hirudo nipponia,or the leech, is not only an important economic pillar for farmers, but is also a precious raw material for medicinal materials. However, in recent years,H. nipponiahas suffered from disease with symptoms including systemic oedema and hyperaemia. It has not yet been demonstrated which pathogen causes this disease and whether this could be transmitted to humans. In this study,Klebsiella pneumoniaewas isolated and identified and the pathogenicity of the isolated strain was confirmed. Furthermore, by comparing the sequence of the pathogen isolated from leeches to the same pathogen infecting humans, we identified that the isolated strain is a threat to human health. This work emphasizes the importance of the first discovery of pathogenic bacteria from leeches similar to human pathogens, as well as the need for identifying zoonosis for both humans and aquatic animals.

Automated summary

Hirudo nipponia, also known as the leech, is important for farmers economically and for medicinal purposes, but in recent years pathogenic bacteria have been identified in leeches that pose a threat to human health. This highlights the importance of understanding zoonotic diseases for both humans and aquatic animals.
