“…M. guilliermondii, which was identified in plant-associated beetles (Suh et al, 2008), mosquitoes (Frants and Mertvetsova, 1986;Steyn et al, 2015) and sand-flies (S. Epis, unpublished data), exerts antimicrobial activities (De Lima et al, 2013) and the ability to over-synthesise the vitamin B2 (Protchenko et al, 2000) that could be useful during the pupal starvation. C. parapsilosis was reported as an antimicrobic in biocontrol applications (Niknejad et al, 2012) and documented for lipase activity (Yalçın et al, 2014). Thus, like M. guilliermondii, its defensive/nutritional symbiosis in insects could be suggested.…”

There is still a lack of studies on fungal microbiota in mosquitoes, compared with the number available on bacterial microbiota. This study reports the identification of yeasts of clinical significance in laboratory mosquito species: Anopheles gambiae, Anopheles stephensi, Culex quinquefasciatus, Aedes albopictus and Aedes aegypti. Among the yeasts isolated, they focused on the opportunistic pathogen Candida parapsilosis, since there is a need to better understand breakthrough candidaemia with resistance to the usual antifungals, which requires careful consideration in the broad-spectrum therapy, as documented in many clinical reports. C. parapsilosis occurs widely and has been isolated from diverse sources, including insects, which may contribute to its dissemination. In this study, it was isolated from the gut of An. gambiae and its presence in developmental stages and organs of different mosquito species was studied. Our results indicated that there was a stable association between C. parapsilosis and reared mosquitoes during the entire life cycle, and in adult male and female gut and gonads. A wide occurrence of C. parapsilosis was also documented in several populations of wild mosquitoes. Based on these findings, it can be said that mosquitoes might participate in the spreading of this opportunistic pathogen, not only as a carrier.

Mixed Infection of Respiratory Tract in a Dog Caused by Rhodotorula mucilaginosa and Trichosporon jirovecii: A Case Report

et al. 2017

This report describes the isolation of two environmental fungi: Rhodotorula mucilaginosa and Trichosporon jirovecii accompanied by Pseudomonas aeruginosa and Escherichia coli from a dog with bronchotracheitis. All microorganisms were isolated routinely from a mucopurulent discharge, obtained during bronchoscopy from laryngotracheal area. The initial identification of yeasts was confirmed by API Candida and by molecular analysis of internal transcribed spacer region. Administered antimicrobial treatment with Marbofloxacin and Canizol has brought the improvement in the dogs’ health status. The final results of control mycological culture were negative. Most probably underlying hypothyroidism and the use of steroids were the factors predisposing this patient to opportunistic infection of mixed aetiology. As far as we are concerned, this is the first case of dogs’ respiratory tract infection caused by R. mucilaginosa and T. jirovecii.

Marine ecosystems are least explored niches for yeast population and diversity. The present study aims to construct a comprehensive DNA barcode library for marine derived yeast species. As, we sequenced ITS gene for 1017 isolates belonging to 157 marine derived yeast species in 55 genera, 28 families, 14 orders, 8 classes of 2 Phyla (viz., Ascomycota and Basidiomycota) among which 13 yeast species were barcoded for the first time, we witnessed yeast species of both terrestrial and endemic marine origin. Difficulties were faced in taxonomic sequence validation due to large volume of sequencing trace files, variable length of sequences extracted and lack of reference sequences in public databases. Majority of the sequences (62.24%) were between 600 and 649 bps in length. K2P intra-species distance analysis conducted for selective groups yielded the average of 0.33% which was well within the previously proposed barcode gap value for yeast species (1.59%). ITS gene tree based identification conducted for selective species in Ascomycota and Basidomycota, precisely clustered the same species in single groups. About 60% of the yeast species recorded in the present study was previously unrecorded from the marine environment, among which 16.5% of yeast species were recognised human pathogens. Apart from releasing the barcode data in GenBank, provisions were made to access the entire dataset along with meta-data in the Barcode of life database under the project title “DNA barcoding marine yeast”. The present study constitutes the biggest dataset for the collection of marine yeast isolates and its DNA barcodes till date.
