Analysis of clinical and environmental Candida parapsilosis isolates by microsatellite genotyping – a tool for hospital infections surveillance

Candida parapsilosis emerged as an important opportunistic pathogen, causing candidaemia worldwide. Nosocomial outbreaks triggered by this species have been frequently described, particularly in cancer patients. For a better understanding of its epidemiology, several typing methods are used and microsatellite analysis has been reported as highly discriminant. The main objective of this work was to study C. parapsilosis isolates by application of microsatellite genotyping to distinguish epidemiologically related strains, compare clinical and environmental isolates and determine possible routes of dispersion of the isolates in the hospital setting. A total of 129 C. parapsilosis isolates from different origins, including hospital environment and hands of healthcare workers, were genotyped using four microsatellite markers. The isolates were recovered from different health institutions. Analysis of C. parapsilosis isolates from hospital environment showed great genotypic diversity; however, the same or very similar genotypes were also found. The same multilocus genotype was shared by isolates recovered from the hand of a healthcare worker, from the hospital environment and from patients of the same healthcare institution, suggesting that these could be possible routes of transmission and that infections due to C. parapsilosis may be mainly related with exogenous transmission to the patient. Examination of sequential isolates from the same patients showed that colonizing and bloodstream isolates had the same multilocus genotype in the majority of cases. We demonstrate that this typing method is able to distinguish clonal clusters from genetically unrelated genotypes and can be a valuable tool to support epidemiologic investigations in the hospital setting.This research was supported by FCT/MEC, Portugal through Portuguese funds (PIDDAC) - Pest-OE/BIA/UI4050/2014 (CBMA), University of Minho.

Mannose binding lectin plays a crucial role in innate immunity against yeast by enhanced complement activation and enhanced uptake of polymorphonuclear cells

<p>Abstract</p> <p>Background</p> <p>Mannose binding lectin (MBL) is an important host defence protein against opportunistic fungal pathogens. This carbohydrate-binding protein, an opsonin and lectin pathway activator, binds through multiple lectin domains to the repeating sugar arrays displayed on the surface of a wide range of clinically relevant microbial species. We investigated the contribution of MBL to antifungal innate immunity towards <it>C. parapsilosis in vitro</it>.</p> <p>Results</p> <p>High avidity binding was observed between MBL and <it>C. albicans </it>and <it>C. parapsilosis</it>. Addition of MBL to MBL deficient serum increased the deposition of C4 and C3b and enhanced the uptake of <it>C. albicans</it>, <it>C. parapsilosis </it>and acapsular <it>C. neoformans </it>by polymorphonuclear cells (PMNs). Compared to other microorganisms, such as <it>Escherichia coli</it>, <it>Staphylococcus aureus </it>and <it>Cryptococcus neoformans</it>, <it>C. parapsilosis </it>and <it>Candida albicans </it>were potent activators of the lectin pathway.</p> <p>Conclusion</p> <p>Our results suggest that MBL plays a crucial role in the innate immunity against infections caused by yeast by increasing uptake by PMN.</p

Secondary health conditions in persons with a spinal cord injury for at least 10 years:design of a comprehensive long-term cross-sectional study

Purpose: To describe the prevalence of secondary health conditions (SHCs) (urinary tract and bowel problems, pressure ulcers, spasticity, musculoskeletal and neuropathic pain, sexual dysfunction, respiratory and cardiovascular disorders) in persons with long-term spinal cord injury (SCI), and to explore the impact of SHCs on fitness, active lifestyle, participation and well-being. Methods: A time since injury (TSI)-stratified cros-ssectional study among 300 persons between 28- and 65-year-old with a SCI for at least 10 years. Strata of TSI are 10-19, 20-29, and 30 or more years. All eight Dutch rehabilitation centres with a SCI unit will participate. Participants will be invited for a 1-day visit to the rehabilitation centre for an aftercare check-up by the local SCI rehabilitation physician (neurological impairment, SHCs and management), physical tests by a trained research assistant (lung function, wheelchair skills, physical capacity), and they will be asked to complete a self-report questionnaire in advance. Results: Not applicable. Conclusion: This study will provide knowledge on the health status and functioning of persons aging with SCI living in the Netherlands. This knowledge will help us to develop predictive models for the occurrence of SHCs and to formulate guidelines to improve health care for persons with long-term SCI.</p
