Especies de levaduras aisladas en muestras de orina en un hospital regional de España

Abstract

Candiduria detection in hospitalized or immunocompromised patients is of great clinical significance. The aim of our study was to describe the isolation frequency of significant species of yeasts in urine samples processed in our hospital during the period 2010- 2013, and to analyze their susceptibility to commonly used antifungal agents. Species identification was performed by seeding on a chromogenic medium, the filamentation test and automated systems (ASM Vitek and MALDI Biotyper), while susceptibility was determined using the ASM Vitek system. Of the 632 yeast isolates in urine, 371 were Candida albicans species and 261 non-C. albicans Candida spp. The species with the highest number of resistant isolates were Candida glabrata and Candida krusei. Based on the results obtained, we believe that species identification and the susceptibility study should be current practice in the laboratories when species other than C. albicans are isolated.

Antibacterial and Antifungal Activity of Propyl-Propane-Thiosulfinate and Propyl-Propane-Thiosulfonate, Two Organosulfur Compounds from Allium cepa: In Vitro Antimicrobial Effect via the Gas Phase

“…In this context, the thiosulfinates derived from Allium spp., such as allicin, have demonstrated broad antifungal activity in numerous in vitro studies against yeasts of the genus Candida [21][22][23]. In the present work, the MICs obtained for antifungals were similar to those obtained in previous research, both in our geographical area [24,25] and in more remote areas [19,[26][27][28][29]. The lowest MICs were obtained for C. albicans and C. tropicalis; the highest for C. glabrata and C. krusei, especially in the case of azoles, which indicates that Candida species remain susceptible to commonly used antifungals and do not represent a problem for the therapeutic approach.…”

Urinary Microbiome: Yin and Yang of the Urinary Tract

“…Different fungal species have been identified in the urine of individuals with urinary tract symptoms such as Clavispora lusitaniae, Lodderomyces elongisporus, Meyerozyma guilliermondii and Malassezia globose , as well as different species belonging to Candida genus, such as C. albicans, C. orthopsilosis, C. tropicalis, C. glabrata, C. lusitaniae , among others ( Heras-Cañas et al., 2015 ; Moustafa et al., 2018 ).…”

Frecuencia y susceptibilidad antifúngica de Candida spp. (no C. albicans) aislada de pacientes de unidades de cuidados críticos de un hospital de tercer nivel del norte del Perú

“…Así mismo, al contrastar la prevalencia de Candida spp. (no C. albicans) con el tipo de muestra, se observó una asociación estadística para ambas variables y el porcentaje de aislamientos es similar a otros estudios (21,29,30) reportado por Heras-Cañas et al (30) , Kaur et al (21) y por Toka Ozer et al (29) . Probablemente La razón de este hallazgo sea que el tracto urinario es una fuente importante de esta levadura no solo porque es comensal de la mucosa sino también por el empleo frecuente de las sondas urinarias en los pacientes de UCI y UCIN.…”
