Nine species of fungi belonging to eight genera of Deuteromycetes were found associated with leaves and fruits of breadfruit, Artocarpus altilis. The fungi were Alternaria alternata (Fries) Keissler, Aspergillus niger Van Tiegh, Aspergillus flavus Link, Colletotrichum gloeosporioides (Penz.) Sacc, Curvularia lunata (Wakker) Boedijn., Penicillium sp. Pteroconium state of   Apiospora camptospora Penz. & Sacc. and Spicaria sp., and Zygosporium oscheoides Mont.. This is the first report of association of A. alternata, C. gloeosporioides., Curvularia lunata,  Penicillium sp. Pteroconium state of A. camptospora, Spicaria sp. and Z. oscheoides, with breadfruit. Colletotrichum gloeosporioides was the predominating fungus recorded on all infected matured leaves showing brown lesion and anthracnose symptom, and also pathogenic to breadfruit plant.

O trabalho teve como objetivos avaliar e correlacionar a qualidade sanitária e fisiológica de sementes de abóbora, variedade Menina Brasileira (Cucurbita moschata.). Foram avaliados dois lotes de sementes de abóbora produzidas no sistema agroecológico e quatro no sistema convencional, com e sem tratamento químico. Os lotes foram submetidos aos testes de sanidade, seguindo a metodologia do "Blotter test", com congelamento, germinação e vigor (primeira contagem, índice de velocidade de germinação, envelhecimento acelerado e emergência de plântulas). Os resultados indicaram a separação dos lotes de diferentes origens a partir da qualidade sanitária e fisiológica, onde as maiores incidências de fungos foram observadas nos lotes agroecológicos e o maior potencial fisiológico foi observado nos lotes de origem convencional não tratados. Foram encontrados os fungos Fusarium oxysporum, Alternaria alternata, Cladosporium cucumerinum, Aspergillus niger, Penicillium digitatum, Rhizopus stolonifer e Phoma terrestris. A qualidade sanitária não interferiu na qualidade fisiológica das sementes de abóbora, variedade Menina Brasileira.

Forty-nine species and 20 genera were collected irora the phyllosphere and phylloplane of wheat plants on 1% glucose and 50% sucrose-Czapek's agar at 28°C. The total counts of phyllospbere and phylloplane fungi displayed seasonal periodicities and the highest counts were found in April and May 1977, 1978. In the case of phyllosphere the most frequent species were <i>Aspergillus niger, Penicillium corylophilum</i> and <i>Alternaria alternata</i>; in the phylloplane <i>Aspergillus niger</i> and <i>A. flavus</i>.

Penelitian ini bertujuan untuk mengetahui (1) beragam spesies jamur patogen tular-benih pada lima varietas padi, dan (2) persentase daya kecambah lima varietas padi. Penelitian dilaksanakan di Laboratorium Karantina Pertanian Kelas I Semarang, dari bulan Maret sampai dengan Mei 2019. Penelitian ini menggunakan Rancangan Acak Lengkap dengan 5 perlakuan dan 5 ulangan, perlakuan terdiri atas Varietas Inpago Unsoed 1, Inpago Unsoed Parimas, IR64, Ciherang, dan Situ Bagendit. Isolasi dan identifikasi jamur patogen tular-benih dilakukan pada blotter test dan medium PDA, dengan pengamatan di bawah mikroskop stereo dan kompon, kemudian dibandingkan dengan pustaka. Variabel yang diamati yaitu morfologi koloni patogen, morfologi patogen, dan daya kecambah. Hasil penelitian menunjukkan bahwa (1) pada semua varietas benih padi terdapat jamur patogen tular-benih, tetapi tidak semua jamur tersebut dijumpai pada setiap varietas. Jenis jamur patogen tular-benih yang dijumpai, yaitu Alternaria padwickii Ganguly, Aspergillus flavus Link, Aspergillus niger van Tieghem, Curvularia lunata (Wakker) Boedjin, Curvularia pallescens Boedjin, Drechslera oryzae Breda de Haan, Fusarium semitectum Berk. & Rav. [W&R, G,B,J], Rhizoctonia solani J. G. Kuhn, Rhizopus oryzae Went & Prins. Geerl., dan Tilletia barclayana Bref., dan (2) uji daya kecambah menunjukkan bahwa masing-masing varietas benih padi memilki persentase daya kecambah benih yang berbeda. Daya kecambah benih berturut-turut pada varietas IR64, Ciherang, Inpago Unsoed 1, Inpago Unsoed Parimas, dan Situ Bagendit sebesar 85,75, 81,75, 80,25, 76,5, dan 70%.

 Objective: This study was aimed to identify the public pattern of presentation, influencing factors, and sort the fungal species, distribution of sex of patients with otomycosis.Results: The predominant complaints were pruritus and found in 76 patients (88.73%), discomfort and pain found in 62 patients (72.09%), aural fullness in 48 patients (55.81%), tinnitus in 34 patients (39.53%), hearing impairment in 50 cases (58.31%), ear discharge in 22 patients (25.58%), and most of the symptoms seen in 36 patients (68.14%). The results showed a total of eight fungal species belong to six different genera, namely, Aspergillus, Candida, Penicillium, Rhizopus, Alternaria, and Cephalosporium were isolated during this study. Among identified fungi, Aspergillus niger was found to be the most prevalent fungal species with 35.71% followed by Candida albicans (27.55%), Aspergillus flavus (10.20%), Aspergillus fumigatus (8.16), Penicillium digitatum (6.12%) and Cephalosporium species (4.08%), and Rhizopus species (5.1%), while Alternaria alternata had the lowest percentage (6.54%).Conclusion: Otomycosis/mycotic otitis externa is still a common problem and there is a rise in the occurrence of otomycosis in latest years, especially in tropical and subtropical humid climates.

In this study, moulds and mycotoxins presence in different tree nuts were investigated. The results showed that all of the 25 samples were contaminated with moulds. Mean values of total mould count varied from 1-4.9 cfu per grain. The most frequent species in hazelnut samples were Rhizopus oryzae (32.2%) and Aspergillus niger (28.9%). In walnuts A. niger (75.6%), in cashews also A. niger (42.4%) while in pistachio samples Alternaria alternata (20.7%), and Cladosporium cladosporioides (20.7%) were the most dominant. Rhizopus oligosporus was the only identified species in all almond samples (100%). Using Enzyme Linked Immunosorbent Assay (ELISA), the presence of total aflatoxins and ochratoxin A was examinated. In all analyzed samples, levels of ochratoxin A were below the limit of detection. Total aflatoxins were detected only in walnut samples with average concentration of 7.1 ?g/kg.

Fifty six spotted rice grain samples of four commercially cultivated rice varieties namely BRRI 28, 29, Kalijira and Pajam were collected from 14 different districts of Bangladesh. Forty rice samples (Hybrid 2,3,4, BR7,11,12,14,16,22,23,25,26and BRRI28 to BRRI 55) were also collected from Bangladesh Rice Research Institute at Joydevpur. Twenty-fivespecies of fungi belonging to 15 genera were associated with these rice varieties. The isolated fungi were Alternaria alternata, Aspergillus clavatus, A. flavus, A. fumigatus, A.niger, A. ochraceus, A.oryzae, A. terreus, Chaetomium globosum, Cladosporium cladosporioides, Colletotrichum gloeosporioides, Curvularia lunata, C. lunata var. aeria, Drechslera oryzae, Fusarium moniliforme, F. oxysporum, F. solani, Microdochium oryzae, Nigrospora oryzae, Penicillium spp., Pestalotiopsis guepinii, Sarocladium oryzae and Trichoderma viride. Amongst these fungi nine i.e. Alternaria alternata (Fr.) Keissler, Aspergillus flavus Link, Curvularia lunata (Wakker) Boedijn, Drechsler aoryzae Breda de Haan (Subramanian and Jain), Fusarium moniliforme Sheldon, F. solani (Mart.) Sacc., Microdochium oryzae (Hashloka and Yokogi) Sam. and Hal., Pestalotiopsis guepinii (Desm.) Stay. and Sarocladium oryzae (Sawada) W. Gams and D. Hawks were found to be pathogenic to rice seeds. The most predominant fungus was D. oryzae which was followed by A. flavus and the least incidence was observed in case of F. solani and P. guepinni. Bioresearch Commu. 7(1): 932-940, 2021 (January)
