It has been rarely reported in the English literature and most of the reported cases have been from US, Saudi Arabia, Kuwait, and Iran. In the last five years, 17 cases have been reported from one or two provinces in Iran, and it seems that it has been undiagnosed or probably unnoticed in other parts of the country.

Case Report of Subcutaneous Entomophthoromycosis with Retroperitoneal Invasion
RELATO DE CASO/CASE REPORT Revista da Sociedade Brasileira de Medicina Tropical 38(4):348-350, jul-ago, 2005 Case report of subcutaneous entomophthoromycosis with retroperitoneal invasion Relato de caso de entomoftoromicose subcutânea com invasão retroperitoneal Leonora Maciel de Souza Vianna1, 2, Marcus Vinícius Guimarães de Lacerda1 and Mário Augusto Pinto de Moraes1 ABSTRACT The authors describe a case of entomophthoromycosis in a previously healthy patient, who presented with an abscess in the right buttock. After surgical drainage it evolved into a retroperitoneal tumor. The patient improved clinically after resection of the mass and ketoconazole treatment. The histopathological analysis showed the Splendore-Hoeppli phenomenon, suggesting Basidiobolus ranarum infection, a zygomycosis generally restricted to the subcutaneous tissue, with rare gastrointestinal involvement. Key-words: Basidiobolus ranarum. Zygomycosis. Entomophthorales. Clinical features. Histopathology. Splendore-Hoeppli phenomenon. RESUMO Os autores descrevem um caso de entomoftoromicose em paciente previamente saudável, que apresentou abscesso em nádega direita, evoluindo, após drenagem cirúrgica, para tumoração retroperitoneal. Após ressecção da massa, o paciente obteve melhora clínica, em uso de cetoconazol. A análise histopatológica evidenciou fenômeno de Splendore-Hoeppli, sugerindo infecção por Basidiobolus ranarum, uma zigomicose geralmente restrita ao tecido subcutâneo, com raro comprometimento gastrintestinal.

Stchigel1, D.A. Sutton2, J.F. Cano-Lira1, F.J. Cabañes3, L. Abarca3, K. Tintelnot4, B.L. Wickes5, D. García1, J. Guarro1 Key words Abstract We have performed a phenotypic and phylogenetic study of a set of fungi, mostly of veterinary origin, morphologically similar to the Chrysosporium asexual morph of Nannizziopsis vriesii (Onygenales, Eurotiomycetidae, animal infections Eurotiomycetes, Ascomycota). The analysis of sequences of the D1-D2 domains of the 28S rDNA, including rep- ascomycetes resentatives of the different families of the Onygenales, revealed that N. vriesii and relatives form a distinct lineage Chrysosporium within that order, which is proposed as the new family Nannizziopsiaceae. The members of this family show the mycoses particular characteristic of causing skin infections in reptiles and producing hyaline, thin- and smooth-walled, small, Nannizziopsiaceae mostly sessile 1-celled conidia and colonies with a pungent skunk-like odour. The phenotypic and multigene study Nannizziopsis results, based on ribosomal ITS region, actin and β-tubulin sequences, demonstrated that some of the fungi included Onygenales in this study were different from the known species of Nannizziopsis and Chrysosporium and are described here as reptiles new. They are N. chlamydospora, N. draconii, N. arthrosporioides, N. pluriseptata and Chrysosporium longisporum. Nannizziopsis chlamydospora is distinguished by producing chlamydospores and by its ability to grow at 5 °C. -

Differences in Fungi Present in Induced Sputum Samples from Asthma
van Woerden et al. BMC Infectious Diseases 2013, 13:69 http://www.biomedcentral.com/1471-2334/13/69 RESEARCH ARTICLE Open Access Differences in fungi present in induced sputum samples from asthma patients and non-atopic controls: a community based case control study Hugo Cornelis van Woerden1*, Clive Gregory1*, Richard Brown2, Julian Roberto Marchesi2, Bastiaan Hoogendoorn1 and Ian Price Matthews1 Abstract Background: There is emerging evidence for the presence of an extensive microbiota in human lungs. It is not known whether variations in the prevalence of species of microbiota in the lungs may have aetiological significance in respiratory conditions such as asthma. The aim of the study was to undertake semi-quantitative analysis of the differences in fungal species in pooled sputum samples from asthma patients and controls. Methods: Induced sputum samples were collected in a case control study of asthma patients and control subjects drawn from the community in Wandsworth, London. Samples from both groups were pooled and then tested for eukaryotes. DNA was amplified using standard PCR techniques, followed by pyrosequencing and comparison of reads to databases of known sequences to determine in a semi-quantitative way the percentage of DNA from known species in each of the two pooled samples. Results: A total of 136 fungal species were identified in the induced sputum samples, with 90 species more common in asthma patients and 46 species more common in control subjects. Psathyrella candolleana, Malassezia pachydermatis, Termitomyces clypeatus and Grifola sordulenta showed a higher percentage of reads in the sputum of asthma patients and Eremothecium sinecaudum, Systenostrema alba, Cladosporium cladosporioides and Vanderwaltozyma polyspora showed a higher percentage of reads in the sputum of control subjects. -

In Vitro and in Situ ACTIVATION of the COMPLEMENT SYSTEM by the FUNGUS Lacazia Loboi
Rev. Inst. Med. trop. S. Paulo 49(2):97-101, March-April, 2007 In vitro AND in situ ACTIVATION OF THE COMPLEMENT SYSTEM BY THE FUNGUS Lacazia loboi Fátima Regina VILANI-MORENO(1), Érika MOZER(2), Ana Márcia Guedes de SENE(2), Margarete de Oliveira FERASÇOLI(2), Tânia Cristina PEREIRA(2), Márcia Garcia MIRAS(2), Gláucia Heloísa de Paula SOUZA(3) & Andréa de Faria Fernandes BELONE(3) SUMMARY Since there are no studies evaluating the participation of the complement system (CS) in Jorge Lobo’s disease and its activity on the fungus Lacazia loboi, we carried out the present investigation. Fungal cells with a viability index of 48% were obtained from the footpads of BALB/c mice and incubated with a pool of inactivated serum from patients with the mycosis or with sterile saline for 30 min at 37 oC. Next, the tubes were incubated for 2 h with a pool of noninactivated AB+ serum, inactivated serum, serum diluted in EGTA-MgCl2, and serum diluted in EDTA. The viability of L. loboi was evaluated and the fungal suspension was cytocentrifuged. The slides were submitted to immunofluorescence staining using human anti-C3 antibody. The results revealed that 98% of the fungi activated the CS by the alternative pathway and no significant difference in L. loboi viability was observed after CS activation. In parallel, frozen histological sections from 11 patients were analyzed regarding the presence of C3 and IgG by immunofluorescence staining. C3 and IgG deposits were observed in the fungal wall of 100% and 91% of the lesions evaluated, respectively. The results suggest that the CS and immunoglobulins may contribute to the defense mechanisms of the host against L.
