“…have been identified mostly based on morphology, but the names applied often do not correlate with DNA sequence-based identifications. Furthermore, the species most commonly reported from humans, C. lunata , appeared to be a species complex ( Berbee et al 1999 , Yanagihara et al 2010 ). Da Cunha et al (2013) recently characterised a set of 99 clinical Curvularia strains from the USA using sequences of the ITS region and the gpd gene.…”

The fungal genus Curvularia includes numerous plant pathogens and some emerging opportunistic pathogens of humans. In a previous study we used morphology and sequences of the nuclear ribosomal internal transcribed spacer region (ITS) and the glyceraldehyde-3-phosphate dehydrogenase (gpd) gene to identify species within a set of 99 clinical Curvularia isolates from the USA. Seventy-two isolates could be identified while the remaining 27 isolates belonged in three unclassified clades that were tentatively labelled Curvularia sp. I, II and III. In the present study, we further assess the taxonomic placement of these isolates using sequences of ITS, gpd, the large subunit rDNA, and the second largest subunit of RNA polymerase II. DNA sequence comparisons with a set of 87 isolates representing 33 Curvularia spp. and members of the closely-related genera Bipolaris and Exserohilum revealed that Curvularia sp. I, II and III represent novel lineages in Curvularia. These lineages are morphologically different from the currently accepted species. In the phylogenetic tree, Curvularia sp. I and sp. III were each split into two distinct lineages. Morphology and phylogeny supported the proposal of five new species, to be named C. americana, C. chlamydospora, C. hominis, C. muehlenbeckiae and C. pseudolunata. The concatenated 4-locus phylogeny revealed the existence of six clades in Curvularia, which are associated with particular morphological features. They were named after representative species, namely americana, eragrostidis, hominis, lunata, spicifera and trifolii.

“…Curvularia and other fungi were seen to colonise the hollow insides of wind instruments like the saxophone, clarinet and flute, leading to hypersensitivity pneumonitis or 'saxophone lung' in the players, an allergic reaction with chronic coughing and wheezing [10,11] . Cutaneous Curvularia lesions have also been reported and the fungus is observed to grow well on keratotic material [12] . The genus Curvularia contains about 80 different species, which are mostly present in soil and plant material.…”

Curvularia belongs to the group of phaeoid or black fungi that can cause opportunistic infections in humans and other animals. Curvularia hawaiiensis or Cochliobolus hawaiiensis (previously Case ReportA 38-year-old previously healthy male who worked as a construction site labourer was brought to the casualty ward of our hospital with a history of loss of consciousness and right ear bleed following a road traffic accident. In the casualty, the patient was conscious and oriented, with a Glasgow Coma Score (GCS) within normal limits. Preliminary investigations including a Computerized Tomography (CT) scan were also normal. He was admitted as an inpatient for further monitoring and evaluation. Routine laboratory investigations were done. An ear swab was also sent for bacterial culture and sensitivity. There were no microorganisms seen in the Gram Stain and the culture plates had no growth in 48 www.jmscr.igmpublication.org Impact Factor 5.84 Index Copernicus Value: 71.58

Abstract. Trianto A, Radjasa OK, Sibero MT, Sabdono A, Haryanti D, Zilullah WOM, Syanindyta AR, Bahry MS, Widiananto PA, Helmi M, Armono HD, Supriadi, Igarashi Y. 2020. The effect of culture media on the number and bioactivity of marine invertebrates associated fungi. Biodiversitas 21: 407-412. Marine ecosystem is rich with microorganisms such as bacteria and fungi either as free-living or in association with macro-organisms. Marine invertebrates provide suitable habitats for fungi by supplying space, food, and other chemicals stuff that in some cases is a reciprocal relationship or called mutualism symbiotic. Some marine invertebrates have interesting activities that are useful for human life such as anticancer, antifungal, and antibacterial. Many reports indicated that the fungal growth and their production of bioactive compounds were highly affected by the media or nutrition. In order to understand the effect of media on the number and bioactivity of the isolates, we collected the samples of marine invertebrates from two locations in Makassar. Invertebrate specimens were collected by hand during SCUBA diving at 3-10 m depths. The fungi were isolated by tapping method either on potato dextrose agar (PDA) or poor marine agar (PMA). The samples were collected from the Samalona water as much as 16 specimens that provided 30 and 18 fungal isolates on PDA and PMA, respectively, while, from the Barrang Cadi water, a total 14 specimens were collected to provide 12 and 3 isolates on PDA and PMA, respectively. All fungi from PMA inhibited the V. harveyi, V. vulnificus, and V. parahaemolyticus with weak, medium, and strong activities, while, the isolates from PDA were mostly not active against the Vibrios. Based on the molecular analyses, the active isolates were identified as Aspergillus flavus, A. oryzae, A. aculeatus, Talaromyces minioluteus, Hypocrea jecorina, Gliomastix murorum, Myrothecium inundatum, and Curvularia avinis. In conclusion, the isolates from PMA showed higher potential as source of antivibrio substances.
