Abstract:
Wohlfahrtiimonas is an infrequently encountered Gram-negative bacterium capable of infecting humans and, in severe instances, precipitating sepsis. Presently, three species within the Wohlfahrtiimonas genus have been identified, with Wohlfahrtiimonas chitiniclastica being the sole species implicated in human infections. To date, there has been only one documented case of human infection with W. chitiniclastica in China. In this study, we present an additional case of human infection with a Wohlfahrtiimonas species. Notably, through 16S rRNA gene sequencing and whole-genome sequencing, the strain was identified as an unclassified species closely related to W. chitiniclastica DSM 18708T.

Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
