“…These data clearly support arguments made previously that S. lignicola and S. dimidiatum are distinct species [6]. Crous et al also rejected as incorrect, the decision by Farr et al [7] to place Scytalidium into synonymy with Fusicoccum and to rename S. dimidatum as Fusicoccum dimidiatum. Another new genus, Neofusicoccum, was described to accommodate Neofusicoccum parvum (0Fusicoccum parvum), Neofusicoccum mangiferae (0Nattrassia mangiferae) and several other species having Botryosphaeria-like teleomorphs [39].…”

“…In a pair-wise comparison, the ITS sequences from the two patient isolates were only 84% similar. A BLAST search with the sequence from UAMH 10614 yielded a 99 to 100% match with three sequences identified in the GenBank as Fusicoccum dimidiatum, a name recently proposed for S. dimidiatum by Farr et al [7] (see taxonomic discussion below), and one sequence of Scytalidium hyalinum. These included AY819727 derived from CBS 499.66 (Centraalbureau voor Schimmelcultures, Utrecht, the Netherlands), AY819728 derived from CBS 204.33 (authentic isolate of Hendersonula toruloidea), AY819726 derived from CBS 251.49 and AY213688 derived from ATCC 38906 (ex-type of S. hyalinum).…”

Disseminated fungal infection in a renal transplant recipient involvingMacrophomina phaseolinaandScytalidium dimidiatum: case report and review of taxonomic changes among medically important members of the Botryosphaeriaceae

We report the first case of human infection with the fungal plant pathogen Macrophomina phaseolina in a Sri Lankan-born Canadian man following a renal transplant in India. The patient subsequently succumbed to invasive infection with Scytalidium dimidiatum. Molecular sequence analysis confirmed the identification of both fungi and revealed that they are related species within the ascomycete family Botryosphaeriaceae. We review the rationale for the recent reclassification of S. dimidiatum as Neoscytalidium dimidiatum and of Nattrassia mangiferae (formerly considered a synanamorph of S. dimidiatum) as Neofusicoccum mangiferae. This and other recent cases illustrate the potential for plant pathogenic fungi to cause invasive human diseases which are refractory to antifungal therapy.

“…These organisms are widespread in the environment, found in soil, wood, and decomposing plant debris, and human infection occurs mainly after traumatic implantation (8,13). S. dimidiatum, one of the human pathogens in this group, was proven to be a major pathogen of onychomycosis and tinea pedis, causing 34.6% and 46% of cases, respectively, in a large study (22).…”

Scytalidium dimidiatum, a dematiaceous fungus, has been well established as an agent of dermatomycosis. There are few reports of invasive infection caused by S. dimidiatum; most infections occurred in immunocompromised hosts. We present an immunocompetent patient with pleural S. dimidiatum infection and review nine other published cases of invasive S. dimidiatum infections. CASE REPORTA 56-year-old male was admitted for evaluation after a few months of progressive dyspnea, fever, night sweats, and loss of weight. His past medical history was significant for rheumatic heart disease, which had necessitated mitral valve commissurotomy 20 years prior to his admission. As a consequence, he suffered from moderate mitral and tricuspid regurgitation and moderate right heart failure, manifesting as chronic pleural effusion. He was treated with 40 mg/day furosemide and warfarin due to chronic atrial fibrillation. The last thoracentesis, performed 3 years earlier, had yielded a bloody exudate, but no pathogen was isolated.On admission the patient appeared cachectic, had mild dyspnea, and was afebrile. The jugular veins were maximally distended. Chest examination revealed dullness to percussion and reduced breath sounds over the right lung base, and a systolic heart murmur was heard at the apex, compatible with mitral regurgitation. Hepatosplenomegaly and moderate peripheral edema were noted as well.Significant laboratory findings were as follows: leukocyte count, 5,600 cells/l with 61% neutrophils; hemoglobin level, 11.7 g/dl; platelet count, 164,000 platelets/l; serum creatinine level, 111 mol/liter; international normalized ratio, 2.41; lactate dehydrogenase, 751 IU/liter; ␥-glutamyl transpeptidase, 133 IU/liter; alkaline phosphatase, 257 IU/liter. Chest computed tomography revealed a large loculated pleural effusion on the right with pleural thickening and total passive collapse of the right middle and lower lobes. Numerous enlarged mediastinal lymph nodes, up to 1.5 cm, were noted. Echocardiography showed enlargement of the right atrium and ventricle, in addition to mitral valve stenosis and regurgitation and moderate pulmonary hypertension.A diagnostic thoracentesis revealed bloody exudative fluid with hemoglobin of 4.3 g/dl and white blood cell count of 2,600 cells/l with 66% neutrophils. The lactate dehydrogenase level was 22,600 IU/liter. Septate hyphae were detected by calcofluor staining (Fig. 1A). Culture on blood agar plates yielded a white hairy mold (Fig. 1B), which progressed into a grayish black fungus (Fig. 1C). MICs were determined by Etest (AB Biodisk, Solna, Sweden). The mold was found to be susceptible to amphotericin B and voriconazole (MICs, 0.032 mg/liter) and to posaconazole (MIC, 0.75 mg/liter) but resistant to fluconazole (MIC, Ͼ256 mg/liter) and itraconazole and caspofungin (MICs, Ͼ32 mg/liter).The patient was treated for 2 weeks with intravenous voriconazole at 4 mg/kg of body weight every 12 h with no clinical or radiological improvement, and an exploratory right thoracotomy was performed.

“…In PDA media the mean growth of mycelia by 96h was 25mm diameter (with 24h, darkness), and its appearance greyish-white to olive-gray and chlamydospores were not observed (Figure 1d). Although, those morphometric characteristics were similar to those reported for N. arbuti in chilean blueberries by Espinoza et al (2009), Farr et al (2005 indicated that N.arbuti has chlamydospores and L/W = [2.3-[3.1 ± 0.4 [-4.2] would be other characteristic to differentiating N. arbuti and N. nonquaesitum (Inderbitzin et al, 2010). Previous study performed on highbush blueberry (cvs.…”

Due to increased incidence of wood fungi from genus Neofusicoccum in highbush blueberry (Vaccinium corymbosum L.) established in various locations in Southern Chile. The objective of this study was the identification of Neofusicocum species in two highbush blueberry cultivars from commercial orchards in Southern Chile. During 2011-12 season, stems with basal cankers and twigs with dieback were collected from cultivars Brigitta and Elliott grown in Panguipulli (39º30'S; 72º 19'W) and Teodoro Schmidt (38°58'S; 73°02'W). Tissues were kept in humid conditions and from cirrus conidia were taken and incubated in PDA medium. The mycelia had a cottony consistency, with colour ranging from greyish-white to black; sub-epidermal pycnidia were eruptive, ostiolate, and brown to black in colour. The unicellular conidia were hyaline, smooth-bordered, coenocytic and septate (1-3), with dense granular content, fusiform and elipsoidal with truncated point, measuring 27.2 ─ 29.4 (±3.0) µm × 7.7 ─ 8.4 (±0.9) µm; length/width ratio (L/W) = 3.6 ±0.6 (n=100). The morphometric characteristics corresponded to those of Neofusicoccum nonquaesitum and corroborated genetically (100% homologation) by rDNA sequencing ITS and was recorded in CABI under number IMI-500168. Whereas, the sequencing was deposited into Genbank (accession number JX217819.1). The pathogenicity of the fungus was consistent in twigs and stems of highbush blueberry cultivars Brigitta and Elliott.
