Abstract. Al-Darraji ZDG, Mohammed-Ameen MKM. 2023. Phenotypic and genotypic diversity of yeast isolated from cancer patients and their environment and their antifungal sensitivity pattern. Biodiversitas 24: 4166-4174. This study aimed to investigate yeast diversity and their antifungal susceptibility patterns in 853 samples collected from cancer patients, their apparently healthy companions, their beds, their tables, and indoor hospital air. The samples were cultured and identified using classical phenotypic characteristics and a molecular method utilizing amplification of ITS conservative regions of rRNA. The sum of phenotyping and genotyping identification revealed that 102 yeast isolates included 6 genera and 14 species. Candida sp. was the most dominant genera (84.31%), followed by Naganishia sp. (10.78%). Candida albicans (24.50%) and C. krusei (16.66%) were the most prevalent yeast species. Fluconazole, caspofungin, and voriconazole exhibited potent antifungal activities against the most yeast species with low minimum inhibitory concentration (MIC) values compared with high MIC (64 µg/mL) values against Meyerozyma guilliermondi, Naganishia difflunes, and C. tropicalis. To conclude, the antifungal activity was isolate- and species-specific and the higher antifungal concentrations led to a more-rapid expression of activity. The high isolation rate of yeasts from beds and tables, advocated the use of various monitoring systems to ensure thorough cleaning and consistent disinfection of surfaces around patients and health care providers. The study findings showed that the molecular method was superior to the phenotyping technique in identifying yeast isolates. While similar research has been performed in different locations, the current project represents a unique milestone for this particular institution, and offers an opportunity to advance research in this area.

“…al., 2008). Closely related to the latter but not so scarcely present in the fungal studies, Botryotrichum was isolated from cucurbit plants (Huang et al, 2020), Rhizophora mangrove trees (Zhou & Xu, 2018), lianas (Bagchi & Banerjee, 2014), orchids like Cattleya species (Lizarazo-Medina et al, 2014), wheat rhizosphere in Iraq (Minati & Mohammed-Ameen, 2020), Eucalyptus spp. in Uruguay (Simeto et al, 2005) and cacao (Schmidt, 2012).…”

Nicotiana glauca it is naturally distributed throughout South America. It was introduced in North America, Europe, Africa, Asia and Oceania and arrived to the Canary Islands as an ornamental plant, where has been invading altered soils. Endophytic fungi are known to produce active compounds that provide protection to their host against diseases and attack of herbivores, these microorganisms being an interesting source of novel molecules. So far, the endophytic fungal communities of Nicotiana have not been studied in the Canary Islands. The goal of this study is to evaluate the diversity of the fungal endophytes community associated with Nicotiana glauca. A total of 36 fungal species were isolated from roots, stems and leaves of plants collected in three locations from Tenerife Island - San Miguel de Abona, Fasnia and Puerto de la Cruz. The highest species richness values were found in leaves and stems (Margalef index = 3.33 and 3.36, respectively) versus roots (Margalef index = 2.52). Simpson's index complements the results of the Margalef index, indicating a fungal community with a high dominance value in roots (D = 0.65) due to the presence of multiple Fusarium species. Fungal community in Fasnia had the highest value of species richness (Margalef index = 3.69 versus 2.17 and 2.27 for San Miguel de Abona and Puerto de la Cruz, respectively). Results indicate fungal specificity to organ and location with 13 genera isolated from a single location and organ, among which rare species like Collariella and Gelasinospora. In this study was detected and isolated for the first time in Canary Islands the fungal species Collariella hilkhuijsenii which is of importance for the ecology of this genus scarcely known. Special attention should be offered to the presence of Fusarium, which possibly relates to the alkaloid production ability of both, the plant and the fungal strains.

“…Another study by [14] isolated several fungi from the Eichhornia crassipes plant, four of which were predominant in the plant and GC-MS analysis indicated that they produced many bioactive compounds. In another study, Theilavia hyalocarpa was isolated with several pathogenic fungi from the winter wheat plant infected with head blight by less than 2% in Basra city [15]. The reason may due to the production of endophytic fungi for secondary metabolites, these fungi live with other microorganisms in the same host, forcing them to compete for nutrition, place and reproduction throughout their life cycle [16].…”

This study was conducted with the aim of isolating endophytic fungi from the xerophyte plant Suaeda aegyptiaca. In this study, Thielavia basicola was isolated from the stem of the plant S. aegyptiaca spread in Basrah city, fungus was identified basis on its morphological features and molecular based on amplification of the ITS gene region and the nucleotide sequence of the fungus was deposited in the Genebank under the accession number MT277121.1. The metabolites of the fungal filtrate T. basicola were identified using by GC-MS technology and the results showed that this fungus produces 40 compounds as extracellular secondary metabolites, the most important of which are 9-Octadecenamide, (Z)- and Tributylacetylcitrate and N-Hexadecanoic acid. This is the first study in which T. basicola is isolated from S. aegyptiaca from desert in Iraq.
