MONACO, Liliana Silvia; BOSIO, Oscar  and  BAVA, Amadeo Javier. Nosocomial candiduria: Etiology and prevalence of its causal agents in Paroissien Hospital. Acta bioquím. clín. latinoam. [online]. 2010, vol.44, n.4, pp.705-709. ISSN 0325-2957.

The present study carried out a retrospective evaluation of the etiology and evolution of the frequency of the causal agents of 300 candiduria events diagnosed in patients assisted at the Paroissien Hospital from 2 January 2000 to 30 December 2009. A total of 33 (11.0%) episodes were dioagnosed in 2000, 26 (8.7%) in 2001, 34 (11.3%) in 2002, 20 (6.7%) in 2003, 30 (10.0%) in 2004, 25 (8.3%) in 2005, 47 (15.7%) in 2006, 27 (9.0%) in 2007, 33 (11.0%) in 2008 and 25 ( 8.3%) in 2009. C. tropicalis, C. albicans, C. glabrata y C. parapsilosis were, in descendent order, the most frequent species involved, with C. guillermondii, C. krusei and C. lusitaniae only exceptionally isolated. C. tropicalis was the most prevalent between 2000-2002, 2004-2006 and in 2008, followed by C. albicans, which was the most prevalent in 2003, 2007 and 2009. C. glabrata was the second species in 2000, 2004 y 2006 and the third in the remaining years studied, except for 2001, 2008 and 2009 when it was displaced by C. Parapsilosis, which held the first place in 2009, along with C. albicans. The results obtained confirm the predominance of the Candida no - albicans species as etiological agents of candiduria in the popularion under study, particularly C. tropicalis, from 2003 onwards, possibly until nowadays. However, due to the lack of previous studies on the subject, it was impossible to determine if the patterns observed are only recent or if they have remained unaltered for longer periods of time.
