Mycoplasma and Ureaplasma Infections in Transplantation: A Big Impact Despite the Lack of a Cell Wall

Abstract

In the general population, Mycoplasma spp. and Ureaplasma spp. are considered as pathogens with low virulence. Asymptomatic urogenital colonization with genital mycoplasmas is common. M. pneumoniae infections most frequently present as tracheobronchitis. In immunosuppressed individuals, a broad spectrum of invasive diseases has been attributed to these pathogens. After kidney transplantation and hematopoietic stem cell transplantation, Mycoplasma spp. and Ureaplasma spp. have been detected as causative pathogens in urogenital infections. Surgical site infections following solid organ transplantation are rarely caused by Mycoplasma spp. and Ureaplasma spp.. Recently, an association between hyperammonemia syndrome and genital mycoplasmas has been described after lung, kidney, and hematopoietic stem cell transplantation.
