Penicillium marneffei, one of the most important thermal dimorphic fungi, is a severe threat to the life of immunocompromised patients. However, the pathogenic mechanisms of P. marneffei remain largely unknown. In this work, we developed a model host by using nematode Caenorhabditis elegans to investigate the virulence of P. marneffei. Using two P.(More)
Penicillium marneffei (P. marneffei) is a human pathogen which persists in macrophages and threatens the immunocompromised patients. To elucidate the mechanisms involved, we investigated the role of extracellular signal-regulated kinases 1 and 2 (ERK1/2) and p38 mitogen-activated protein kinase (p38) pathways in cytokine expression, phagosome-lysosome(More)
Penicillium marneffei, a dimorphic fungus that can cause penicilliosis marneffei, is endemic in Southeast Asia. The only known hosts of P. marneffei are humans and bamboo rats. The aim of our study was to explore the distribution of P. marneffei in bamboo rats, their associated environment and non-rat-associated environments. Totally, 270 samples were(More)
Chromoblastomycosis, a chronic fungal infection of skin and subcutaneous tissue caused by dematiaceous fungi, is associated with low cure and high relapse rates. Among all factors affecting clinical outcome, etiological agents have an important position. In southern China, Fonsecaea pedrosoi and Fonsecaea monophora are main causative agents causing(More)
Increases in cytosolic Ca(2+) concentration ([Ca(2+)]c) promote phagocyte antimicrobial responses. Here, we investigated macrophages stimulated by Penicillium marneffei (P. marneffei). [Ca(2+)]c was determined in macrophages loaded with the fluorescent calcium probe Fura 2/AM as they were stimulated by P. marneffei. We found that P. marneffei induced an(More)
Penicilliosis marneffei, often consecutive to the aspiration of Talaromyces marneffei (Penicillium marneffei), continues to be one of the significant causes of morbidity and mortality in immunocompromised patients in endemic regions such as Southeast Asia. Improving the accuracy of diagnosing this disease would aid in reducing the mortality of associated(More)
Penicillium marneffei (P. marneffei) is a human pathogen which persists in macrophages and threatens the immunocompromised patients. To clarify the mechanisms involved, we evaluated the effect of c-Jun N-terminal kinase 1 and 2 (JNK1/2) on cytokine expression, phagosomal maturation and multiplication of P. marneffei in P. marneffei-stimulated human(More)
Penicillium marneffei, the only known dimorphic and pathogenic species in the genus of Penicillium, is responsible for severe to deadly infection in immunocompromised patients. In this study, P. marneffei was able to infect the greater wax moth Galleria mellonella. The increasing inoculum doses of P. marneffei cells resulted in greater larval mortality, and(More)
Sporothrix globosa is a thermo-dimorphic fungus belonging to a pathogenic clade that also includes Sporothrix schenckii, which causes human and animal sporotrichosis. Here, we present the first genome assemblies of two S. globosa strains providing data for future comparative genomic studies in pathogenic Sporothrix species.
Cutaneous mucormycosis, an uncommon disease caused by Mucorales, predominantly occurs in immunocompromised host. The present case is a primary cutaneous mucormycosis due to Mucor indicus in an immunocompetent individual. It is with the features of necrotizing fasciitis over the right pretibial area. We are presenting this case owing to its rarity and the(More)
