    Next-Generation Sequencing for Hypothesis-Free Genomic Detection

    Frickmann et al. BMC Microbiology (2019) 19:75 https://doi.org/10.1186/s12866-019-1448-0 RESEARCH ARTICLE Open Access Next-generation sequencing for hypothesis- free genomic detection of invasive tropical infections in poly-microbially contaminated, formalin-fixed, paraffin-embedded tissue samples – a proof-of-principle assessment Hagen Frickmann1,2* , Carsten Künne3, Ralf Matthias Hagen4, Andreas Podbielski2, Jana Normann2, Sven Poppert5,6, Mario Looso3 and Bernd Kreikemeyer2 Abstract Background: The potential of next-generation sequencing (NGS) for hypothesis-free pathogen diagnosis from (poly-)microbially contaminated, formalin-fixed, paraffin embedded tissue samples from patients with invasive fungal infections and amebiasis was investigated. Samples from patients with chromoblastomycosis (n = 3), coccidioidomycosis (n = 2), histoplasmosis (n = 4), histoplasmosis or cryptococcosis with poor histological discriminability (n = 1), mucormycosis (n = 2), mycetoma (n = 3), rhinosporidiosis (n = 2), and invasive Entamoeba histolytica infections (n = 6) were analyzed by NGS (each one Illumina v3 run per sample). To discriminate contamination from putative infections in NGS analysis, mean and standard deviation of the number of specific sequence fragments (paired reads) were determined and compared in all samples examined for the pathogens in question. Results: For matches between NGS results and histological diagnoses, a percentage of species-specific reads greater than the 4th standard deviation above the mean value of all 23 assessed sample materials was required. Potentially etiologically relevant pathogens could be identified by NGS in 5 out of 17 samples of patients with invasive mycoses and in 1 out of 6 samples of patients with amebiasis. Conclusions: The use of NGS for hypothesis-free pathogen diagnosis from contamination-prone formalin- fixed, paraffin-embedded tissue requires further standardization.

The article reviews common clinical types of candidiasis, its diagnosis current treatment modalities with emphasis on the role of prevention of recurrence in the susceptible dental patient. The dental hygienist can play an important role in education of patients to prevent recurrence. The frequency of invasive fungal infections (IFIs) has increased over the last decade with the rise in at‐risk populations of patients. The morbidity and mortality of IFIs are high and management of these conditions is a great challenge. With the widespread adoption of antifungal prophylaxis, the epidemiology of invasive fungal pathogens has changed. Non‐albicans Candida, non‐fumigatus Aspergillus and moulds other than Aspergillus have become increasingly recognised causes of invasive diseases. These emerging fungi are characterised by resistance or lower susceptibility to standard antifungal agents. Oral candidiasis is a common fungal infection in patients with an impaired immune system, such as those undergoing chemotherapy for cancer and patients with AIDS. It has a high morbidity amongst the latter group with approximately 85% of patients being infected at some point during the course of their illness. A major predisposing factor in HIV‐infected patients is a decreased CD4 T‐cell count.

ABSTRACT Keywords: Fungus; Fungal infections due to pathogenic or opportunistic fungi may be superficial, cutaneous, subcutaneous Mycosis; and systemic. With the upsurge of at risk population systemic fungal infections are increasingly common. Opportunistic; Diagnosis of fungal infections may include several modalities including histopathology of affected tissue Systemic which reveal the morphology of fungi and tissue reaction. Fungi can be in yeast and / or hyphae forms and tissue reactions may range from minimal to acute or chronic granulomatous inflammation. Different fungi should be differentiated from each other as well as bacteria on the basis of morphology and also clinical correlation. Special stains like GMS and PAS are helpful to identify fungi in tissue sections.

Summary statement of the proposal for inclusion, change or deletion As a growing trend of invasive fungal infections has been noticed worldwide, available few antifungal drugs requires to be used optimally. Invasive aspergillosis, systemic candidiasis, chronic pulmonary aspergillosis, fungal rhinosinusitis, allergic bronchopulmonary aspergillosis, phaeohyphomycosis, histoplasmosis, sporotrichosis, chromoblastomycosis, and relapsed cases of dermatophytosis are few important concern of southeast Asian regional area. Considering the high burden of fungal diseases in Asian countries and its associated high morbidity and mortality (often exceeding 50%), we support the application of including major antifungal drugs against filamentous fungi, itraconazole and voriconazole in the list of WHO Essential Medicines (both available in oral formulation). The inclusion of these oral effective antifungal drugs in the essential list of medicines (EML) would help in increased availability of these agents in this part of the world and better prompt management of patients thereby reducing mortality. The widespread availability of these drugs would also stimulate more research to facilitate the development of better combination therapies.

    IDENTIFICATION OF CULTURE-NEGATIVE FUNGI IN BLOOD AND RESPIRATORY SAMPLES Farida P. Sidiq A Dissertation Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY May 2014 Committee: Scott O. Rogers, Advisor W. Robert Midden Graduate Faculty Representative George Bullerjahn Raymond Larsen Vipaporn Phuntumart © 2014 Farida P. Sidiq All Rights Reserved iii ABSTRACT Scott O. Rogers, Advisor Fungi were identified as early as the 1800’s as potential human pathogens, and have since been shown as being capable of causing disease in both immunocompetent and immunocompromised people. Clinical diagnosis of fungal infections has largely relied upon traditional microbiological culture techniques and examination of positive cultures and histopathological specimens utilizing microscopy. The first has been shown to be highly insensitive and prone to result in frequent false negatives. This is complicated by atypical phenotypes and organisms that are morphologically indistinguishable in tissues. Delays in diagnosis of fungal infections and inaccurate identification of infectious organisms contribute to increased morbidity and mortality in immunocompromised patients who exhibit increased vulnerability to opportunistic infection by normally nonpathogenic fungi. In this study we have retrospectively examined one-hundred culture negative whole blood samples and one-hundred culture negative respiratory samples obtained from the clinical microbiology lab at the University of Michigan Hospital in Ann Arbor, MI. Samples were obtained from randomized, heterogeneous patient populations collected between 2005 and 2006. Specimens were tested utilizing cetyltrimethylammonium bromide (CTAB) DNA extraction and polymerase chain reaction amplification of internal transcribed spacer (ITS) regions of ribosomal DNA utilizing panfungal ITS primers.

    Editorial | Journal of Gandaki Medical College-Nepal Fungal Infections (Mycoses): Dermatophytoses (Tinea, Ringworm) Reddy KR Professor & Head Microbiology Department Gandaki Medical College & Teaching Hospital, Pokhara, Nepal Medical Mycology, a study of fungal epidemiology, ecology, pathogenesis, diagnosis, prevention and treatment in human beings, is a newly recognized discipline of biomedical sciences, advancing rapidly. Earlier, the fungi were believed to be mere contaminants, commensals or nonpathogenic agents but now these are commonly recognized as medically relevant organisms causing potentially fatal diseases. The discipline of medical mycology attained recognition as an independent medical speciality in the world sciences in 1910 when French dermatologist Journal of Raymond Jacques Adrien Sabouraud (1864 - 1936) published his seminal treatise Les Teignes. This monumental work was a comprehensive account of most of then GANDAKI known dermatophytes, which is still being referred by the mycologists.
