| Abstract |
The Candida haemulonii complex (Candida haemulonii, Candida haemulonii var. vulnera, and Candida duobushaemulonii) comprises emerging opportunistic human fungal pathogens with recognized multidrug-resistance profiles. Little is known about the virulence markers produced by this fungal complex. However, it is recognized that Candida spp. express a large array of peptidases, which play multiple roles in different aspects of fungal-host interactions. In the present study, we have identified proteolytic enzymes in clinical isolates of the C. haemulonii complex using zymographic assays. Peptidases able to hydrolyze gelatin, casein, albumin, hemoglobin, and immunoglobulin G were detected in cell-free supernatants and cellular extracts taken from the three species forming the C. haemulonii complex. Overall, peptidases were preferentially evidenced at physiological pH and temperatures of 37-42 °C, with molar masses between 35 and 85 kDa. Peptidase profiles of C. haemulonii and C. haemulonii var. vulnera isolates were quite similar, contrasting to the peptidases produced by C. duobushaemulonii. Almost all peptidases were inhibited by phenylmethanesulfonyl fluoride (PMSF), thus classifying them as serine-type peptidases. Additionally, proteolytic cleavage of soluble azoalbumin was blocked by PMSF (65-95% inhibition depending on the fungal isolate). These unprecedented results have demonstrated the capability of the C. haemulonii complex to produce serine-type peptidases with an ability to cleave a broad spectrum of proteins, including key host components. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 September 2018.
All research outputs
#20,535,139
of 23,105,443 outputs
Outputs from Folia Microbiologica
#610
of 750 outputs
Outputs of similar age
#296,864
of 341,556 outputs
Outputs of similar age from Folia Microbiologica
#7
of 17 outputs
Altmetric has tracked 23,105,443 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 750 research outputs from this source. They receive a mean Attention Score of 2.9. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 341,556 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 17 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
