PURPOSE: Mucormycosis encompasses a group of opportunistic fungal infections caused by Zygomycetes, order Mucorales. Mucormycosis can manifest as rhino-orbito-cerebral, pulmonary, gastrointestinal, cutaneous, and disseminated infections. Pulmonary mucormycosis is the second most common presentation. This manuscript characterizes the demographics, clinical presentation, diagnostic procedures, radiologic findings, therapeutic interventions, and outcome in pulmonary mucormycosis. METHODS: We retrospectively reviewed clinical data of 35 patients with pulmonary mucormycosis from 2000 to 2015...

The Philippines is a low middle-income, tropical country in Southeast Asia. Infectious diseases remain the main causes of morbidity, including tuberculosis. AIDS/HIV prevalence is still low at <1%, but is rapidly increasing. Fungal disease surveillance has not been done, and its burden has never been estimated. This becomes more important as the population of immunocompromised patients increases, drawn from patients with AIDS, TB, malignancies, and autoimmune diseases requiring chronic steroid use. Using the methodology of the LIFE program ( www...

The detection of pulmonary mold infections has historically required technically demanding methods obtained through invasive procedures. Nucleic acid amplification assays have the potential to circumvent the technical hurdles associated with diagnosis, but are not without potential pitfalls. Areas covered: In this paper, the authors review new assays for the diagnosis of pulmonary mold infections due to aspergillosis, mucormycosis, and hyalohyphomycoses as well as uncommon infections caused by dematiaceous molds...

Viplendra P S Shakya, Alexander Idnurm
Light is an environmental signal that influences reproduction in the Mucoromycotina fungi, as it does in many other species of fungi. Mating in Phycomyces blakesleeanus is inhibited by light, but the molecular mechanisms for this inhibition are uncharacterized. In this analysis, the role of the light-sensing MadA-MadB complex in mating was tested. The MadA-MadB complex is homologous to the Neurospora crassa White Collar complex. Three genes required for cell type determination in the sex locus or pheromone biosynthesis are transcriptionally-regulated by light and are controlled by MadA and MadB...

We describe a rhinofacial entomophthoramycosis case in a sexagenarian (65 years old) housewife. She was immunocompetent and resident of Burkina Faso. She consulted both the service of dermatology and the service of stomatology of the Teaching Hospital of Bobo-Dioulasso in February 2016 for a diffuse facial tumefaction evolving over six months. This tumefaction was associated with headaches and a left nasal obstruction. Histological examination of the lesion showed an important and polymorphic inflammatory reaction...

AIM: Mucormycosis is a fungal infection associated with high mortality. Until recently, the only licensed treatments were amphotericin B (AMB) formulations. Isavuconazole (ISAV) is a new mucormycosis treatment. A UK-based economic model explored treatment costs with ISAV versus liposomal AMB followed by posaconazole. MATERIALS & METHODS: As a matched case-control analysis showed similar efficacy for ISAV and AMB, a cost-minimization approach was taken. Direct costs - drug acquisition, monitoring and administration, and hospitalization costs - were estimated from the National Health Service perspective...

BACKGROUND: Acute invasive fungal rhinosinusitis (AIFRS) represents a fulminant, potentially fatal, disease process in immunocompromised patients. The diagnosis often rests on high index of clinical suspicion, with relative paucity of data on the diagnostic and therapeutic implications of intraoperative frozen sections. METHODS: Retrospective review was performed for 18 cases undergoing endoscopic sinus surgery for AIFRS. Reliability of intraoperative frozen section diagnosis was evaluated for all patients using final pathology as the gold standard...

Fusarium wilt is one of the main diseases of cucumber, and bio-organic fertilizer has been used to control Fusarium wilt. In this study, a pot experiment was conducted to evaluate the effects of bio-organic fertilizer applied at four levels on the suppression of Fusarium wilt disease in cucumber, the soil physico-chemical properties and the microbial communities. In comparison with the control (CK), low concentrations of bio-organic fertilizer (BIO2.5 and BIO5) did not effectively reduce the disease incidence and had little effect on soil microorganisms...

Ruminants infected by Paramphistomidae flukes shed eggs in the feces, which pass through different stages in the environment until the infective stages (metacercariae) are reached. The activity of the soil fungus Mucor circinelloides on the development of eggs of the rumen fluke Calicophoron daubneyi was presently tested with 3 probes, i.e., in Petri plates, feces and an aqueous environment (tubes). The effect of the fungus was assessed by recording the numbers of undeveloped, non-viable and embryonated eggs...

The true burden of fungal infection in Pakistan is unknown. High-risk populations for fungal infections [tuberculosis (TB), diabetes, chronic respiratory diseases, asthma, cancer, transplant and human immunodeficiency virus (HIV) infection] are numerous. Here, we estimate the burden of fungal infections to highlight their public health significance. Whole and at-risk population estimates were obtained from the WHO (TB), BREATHE study (COPD), UNAIDS (HIV), GLOBOCAN (cancer) and Heartfile (diabetes). Published data from Pakistan reporting fungal infections rates in general and specific populations were reviewed and used when applicable...

As a first description to document the species richness in Dal Lake, a freshwater lake ecosystem in Kashmir valley, an extensive network of sixteen sampling stations with distinguishing features was sampled seasonally for two years. The identification process yielded fifty-one species probably first and new records for this area to date. The taxonomic groups observed were those with species from Ascomycetes (inclusive of yeasts), Basidiomycetes, Blastocladiomycetes, Zygomycetes, and Peronosporomycetes. Each phylum was represented by a single Order, with the exception of the Peronosporomycetes, which was represented by two Orders- Saprolegniales and Pythiales...

In recent years, there have been major advances in the treatment of chronic lymphocytic leukemia (CLL) particularly since the development of novel therapeutic agents, mostly "biological drugs." One of the obvious advantages of these agents is the decreased rate of infectious complications occurring during the course of therapy, compared to the use of standard immuno-chemotherapy regimens. Here, we describe 3 patients with CLL and 1 with mantle cell lymphoma who developed severe life-threatening pneumonias, during monotherapy with ibrutinib...

While surveying the diversity of fungi of the order Mucorales, two isolates, EML-PUKI12-1 and EML-PUKI06-1, were obtained from the gut of soldier fly larvae inhabiting the bulrush at a pond located in the Chonnam National University Arboretum, Gwangju, Korea. The isolates were confirmed as Mucor irregularis and Mucor fragilis species, respectively, based on the morphological characteristics and phylogenetic analysis of rDNA internal transcribed spacer region. Such mucoralean species belonging to undiscovered taxa has not previously been described in Korea...

Chitosan, a β-1,4-linked glucosamine polymer is formed by deacetylation of chitin. It has a wide range of applications from agriculture to human health care products. Chitosan is commercially produced from shellfish, shrimp waste, crab and lobster processing using strong alkalis at high temperatures for long time periods. The production of chitin and chitosan from fungal sources has gained increased attention in recent years due to potential advantages in terms of homogenous polymer length, high degree of deacetylation and solubility over the current marine source...

Changes in the health of individuals within wildlife populations can be a cause or effect of population declines in wildlife species. Aspects of individual platypus ( Ornithorhynchus anatinus ) health have been reported. However, holistic studies investigating potential synergistic effects of both pathogens and environmental factors are needed to expand understanding of platypus individual health. We collected baseline data on the health of platypuses in two Tasmanian river catchments (including evidence of the potentially fatal fungal disease mucormycosis) and on individual, demographic, geographic, and temporal patterns associated with health data results...

To assess whether Fourier Transform Infrared (FTIR) spectroscopy could be used to evaluate and monitor lipid extraction processes, the extraction methods of Folch, Bligh and Lewis were used. Biomass of the oleaginous fungi Mucor circinelloides and Mortierella alpina were employed as lipid-rich material for the lipid extraction. The presence of lipids was determined by recording infrared spectra of all components in the lipid extraction procedure, such as the biomass before and after extraction, the water and extract phases...

Mucorales are an emerging group of human pathogens that are responsible for the lethal disease mucormycosis. Unfortunately, functional studies on the genetic factors behind the virulence of these organisms are hampered by their limited genetic tractability, since they are reluctant to classical genetic tools like transposable elements or gene mapping. Here, we describe an RNAi-based functional genomic platform that allows the identification of new virulence factors through a forward genetic approach firstly described in Mucorales...

In 23 leukemia patients with proven (n = 17) or possible (n = 6) pulmonary mucormycosis (PM), the presence of reversed halo sign on computed tomography was strongly associated with the positivity of quantitative polymerase chain reaction assays targeting Mucorales in the serum, confirming the value of these two tools for the diagnosis of PM in this setting.
