“…Due to the collocation of the novel species in the Yamadazyma clade, the novel species has been named Yamadazyma terventina and not Candida terventina , according to the ‘one fungus – one name’ recommendation (Hawksworth, 2011). The closest relatives were Candida conglobata (42 substitutions equivalent to 3.33 % difference), Candida aaseri (50 substitutions equivalent to 3.97 % difference), a synonym of the butter contaminant Candida butyri (Pfüller et al , 2011) isolated from butter and at low frequency in cases of mastitis (Spanamberg et al , 2008) and Yamadazyma scolyti (61 substitutions equivalent to 4.84 % difference). Members of the clade rather distant to the novel species were Yamadazyma triangularis , a yeast of clinical relevance, isolated in lung tissue and considered as a potential opportunistic pathogen (99 substitutions, equivalent to 7.86 % difference) (Kurtzman et al , 2011a; Smith & Batenburg-Van der Vegte, 1986) and Yamadazyma philogaea (73 substitutions, equivalent to 5.79 % difference) (Robiglio et al , 2011; van der Walt & Johannsen, 1975).…”

During an investigation of olive oil microbiota, three yeast strains were found to be divergent from currently classified yeast species according to the sequences of the D1/D2 domain of the gene encoding the rRNA large subunit (LSU) and the internal transcribed spacer region including the gene for 5.8S rRNA. Phylogenetic analysis revealed that these strains, designated CBS 12509, CBS 12510T and CBS 12511, represent a novel anascosporogenous species described herein as Yamadazyma terventina sp. nov; the type strain is DAPES 1924T ( = CBS 12510T = NCAIM Y.02028T). This novel species was placed in the Yamadazyma clade, with Yamadazyma scolyti, Candida conglobata and Candida aaseri as closest relatives. Y. terventina differs from the above-mentioned species in the ability to strongly assimilate dl-lactate and weakly assimilate ethanol.

“…The relative cell-surface hydrophobicity (CSH) of C. parapsilosis , adherence to host tissues and plastic surfaces such as milkers or other prosthetic materials [ 23 – 25 ], and the presence of pathogenic strains of C. krusei might also contribute the high rate of C . krusei and C. parapsilosis in milk samples of cow mastitis [ 26 ].…”

BackgroundCandida spp. is the vital pathogen involved in mycotic mastitis of cows. However the epidemiology and infection of Candida species in mycotic mastitis of cow in Ningxia province of China has not been explored. In the present study, the epidemiology, antimicrobial susceptibility and virulence-related genes of non-albicans Candida (NAC) species were investigated.MethodsA total of 482 milk samples from cows with clinical mastitis in four herds of Yinchuan, Ningxia were collected and used for the isolation and identification of mastic pathogens by phenotypic and molecular characteristics, and matrix-assisted laser desorption ionization-time of flight mass spectrometry. The antimicrobial susceptibility to antifungal agents was also determined by a disk diffusion assay. The presence of virulence-related genes was determined by polymerase chain reaction (PCR).ResultsA total of 60 isolates from nine different Candida species were identified from 256 (60/256, 23.44%) milk samples. The most frequently identified species in cows with clinical mastitis groups were Candida krusei (n = 14) and Candida parapsilosis (n = 6). Others include Candida lipolytica, Candida lusitaniae, Cryptococcus neoformans. But no Candida albicans was identified in this study. Interestingly, All C. krusei isolates (14/14) were resistant to fluconazole, fluorocytosine, itraconazole and ketoconazole, 2 out of 14 C. krusei were resistant to amphotericin, and 8 out of the 14 were resistant to nystatin. Similarly, all six C. parapsilosis isolates were resistant to fluorocytosine, but susceptible to fluconazole, ketoconazole and nystatin; two of the six were resistant amphotericin and itraconazole. Molecularly, all of the C. parapsilosis isolates carried eight virulence-related genes, FKS1, FKS2, FKS3, SAP1, SAP2, CDR1, ERG11 and MDR1. All of the C. krusei isolates contained three virulence-related genes, ERG11, ABC2 and FKS1.ConclusionThese data suggested that Candida species other than C. albicans played a pathogenic role in mycotic mastitis of cows in Yinchuan, Ningxia of China. The high incidence of drug-resistant genes in C. parapsilosis and C. krusei also highlighted a great concern in public and animal health in this region.

“…A cultivation-based study from 2008, which analyzed Brazilian subclinical mastitis milk samples, found that Candida, Pichia, Cryptococcus and Rhodotorula were the most frequent genera. However, they could not be directly linked to the subclinical mastitis state in the mentioned publication [35]. Regarding Cryptococcus and Candida, we were unable to identify Cryptococcus reads in any one of the milk samples, but for Candida, we identified Candida boidinii, Candida metapsilosis, Candida intermedia, Candida zeylanoides and Candida pararugosa.…”

Full-Length SSU rRNA Gene Sequencing Allows Species-Level Detection of Bacteria, Archaea, and Yeasts Present in Milk

Full-length SSU rRNA gene sequencing allows species-level identification of the microorganisms present in milk samples. Here, we used bulk-tank raw milk samples of two German dairies and detected, using this method, a great diversity of bacteria, archaea, and yeasts within the samples. Moreover, the species-level classification was improved in comparison to short amplicon sequencing. Therefore, we anticipate that this approach might be useful for the detection of possible mastitis-causing species, as well as for the control of spoilage-associated microorganisms. In a proof of concept, we showed that we were able to identify several putative mastitis-causing or mastitis-associated species such as Streptococcusuberis, Streptococcusagalactiae, Streptococcusdysgalactiae, Escherichiacoli and Staphylococcusaureus, as well as several Candida species. Overall, the presented full-length approach for the sequencing of SSU rRNA is easy to conduct, able to be standardized, and allows the screening of microorganisms in labs with Illumina sequencing machines.
