“…Until now, only few reports have been made on unrecorded Aspergillus species from Korea despite the ubiquitous distribution. However, there has also been an increase in the reports of several new Aspergillus species throughout the world [ 13 , 17 ].…”

: Aspergillus subgenus Nidulantes with nine section forms the second largest subgenus of the fungi that comes under the genus Aspergillus. Species in this group of fungi are important as they are reported to play several important roles in the environment including influencing air quality in confined spaces, food spoilage, production of mycotoxins as well as in human pathogenicity. In the present study, 53 strains of Aspergillus subgenus Nidulantes (section: Nidulantes & Usti ) isolated from Korea and preserved at the Korean Agricultural Culture Collection (KACC) were subjected to re-identification by using a combined dataset of partial β-tubulin ( BenA ), Calmodulin ( CaM ) gene sequences as well as their morphological data. We confirmed 14 species from 53 isolates in Korea. Of them, eleven species were reported in Korea previously ( A. amoenus , A. baeticus , A. calidoustus , A. creber , A. insuetus , A. jensenii , A. nidulans , A. protuberus, A. sydowii , A. tabacinus and A. unguis ), and three species ( A. griseoaurantiacus , A. puulaauensis and A. sublatus ) were previously unreported from Korea. We detailed the characteristic features of these three species, that remain unexplored in Korea.

“…Gibberella is a plant pathogen ( Desjardins, 2003 ), Aspergillus spp. are environmental saprobes ( Pangging et al, 2022 ), Cladosporium is ubiquitous among various organic materials ( Salvatore et al, 2021 ) and Penicillium is often associated with food ( Yadav et al, 2018 ).…”

Temporal dynamics of the chicken mycobiome

The microbiome is an integral part of chicken health and can affect immunity, nutrient utilization, and performance. The role of bacterial microbiota members in host health is relatively well established, but less attention has been paid to fungal members of the gastrointestinal tract (GIT) community. However, human studies indicate that fungi play a critical role in health. Here, we described fungal communities, or mycobiomes, in both the lumen and mucosa of the chicken ileum and cecum from hatch through 14 days of age. We also assessed the effects of delayed access to feed immediately post-hatch (PH) on mycobiome composition, as PH feed delay is commonly associated with poor health performance. Chicken mycobiomes in each of the populations were distinct and changed over time. All mycobiomes were dominated by Gibberella, but Aspergillus, Cladosporium, Sarocladium, Meyerozyma, and Penicillium were also abundant. Relative abundances of some taxa differed significantly over time. In the cecal and ileal lumens, Penicillium was present in extremely low quantities or absent during days one and two and then increased over time. Meyerozyma and Wickerhamomyces also increased over time in luminal sites. In contrast, several highly abundant unclassified fungi decreased after days one and two, highlighting the need for improved understanding of fungal gut biology. Mycobiomes from chicks fed during the first 2 days PH versus those not fed during the first 2 days did not significantly differ, except during days one and two. Similarities observed among mycobiomes of fed and unfed chicks at later timepoints suggest that delays in PH feeding do not have long lasting effects on mycobiome composition. Together, these results provide a foundation for future mycobiome studies, and suggest that negative health and production impacts of delayed feeding are not likely related to the development of fungal populations in the GIT.

“…Local environmental variables, such as physical and chemical soil features, influence the diversity of soil fungi ( Tardy et al, 2015 ), which in turn strongly affects the current diversity of fungal communities ( Requena et al, 2001 ). Aspergillus is a diverse genus followed by a large number of species, which covers all countries of the world and is found in different climatic conditions, as well as in different soil types ( Burrough et al, 2012 ; Monmi, Nguyen & Lee, 2022 ). It is also known for its secretion of mycotoxins, as well as its ability to spoil food, in addition, it is known for high pathogenicity to humans and animals ( Frisvad et al, 2011 ; Hussein, El-Said & Yassein, 2020 ; Wei et al, 2022 ).…”

“…Furthermore, molecular markers used in Aspergillus have included the internal transcription spacer sequence (ITS), calodulin (CaM), and β -tubulin (BenA), Tef1 gene and RNA polymerase II second largest subunit (RPB2) sequences. The molecular marker is employed for identifying Aspergillus species because of the extensive gene database available, the relative simplicity of locus amplification, and genetic polymorphism ( Samson et al, 2014 ; Raja et al, 2017 ; Monmi, Nguyen & Lee, 2022 ). These locus are insufficient to identify all Aspergillus species correctly, thus secondary identification parameters such as the SCAR marker are needed ( Hassan, Farid & Gaber, 2019 ).…”

Background The carcinogenic, mutagenic, and teratogenic chemicals such as aflatoxin are a worldwide health problem. Aspergillus spp., responsible for most cases of aflatoxin contamination, are common in the environment and spread easily to many different types of food. The objectives of this study were to conduct a survey of fungi associated with three soil invertebrates in Taif, Saudi Arabia, identify these isolates and explore mycotoxins formation. Methods In total, 114 fungal isolates were collected from various soil invertebrates (millipedes, Armadillidium vulgare and Porcellio laevis) in Taif, Saudi Arabia, among them, 22 isolates were identified as Aspergillus spp. based on morphological and molecular characteristics followed by both Fusarium and Penicillium. Results The sequences of ITS 1 and ITS 4 were utilized. Using bootstrap analysis, phylogenetic tree was split into two distinct clusters. Five sub clusters were included inside the first major cluster, and their bootstrap value was 99%. While, there were two small clusters in the second major cluster. All the tested Aspergillus strains were able to have a single PCR fragment amplified using the primer AspTef. TEF-1 DNA sequence bootstrap analysis with 1,000 replicates revealed two distinct groups. Additionally, the Aspergillus isolates were grouped into two different clusters with about 65% genetic similarity using ISSR-PCR analysis. The standard polymerase chain reaction was used to effectively amplify the Aopks, afl-A and omt-A genes in aflatoxigenic Aspergillus strains. Four Aspergillus strains used in this investigation were shown to generate aflatoxin B1. While, three Aspergillus stains showed ochratoxin genes. Conclusions In conclusion, the results indicate significant differences in the fungal community between ecoregions and soil invertebrates. Moreover, mycotoxin detection and identification among Aspergillus isolates were elucidated. This study could shed light on the risk of mycotoxin contamination along the supply chain.
