Pulmonary mucormycosis, a relatively rare pulmonary fungal disease, is difficult to diagnose and lacks effective treatment. The present study reports the case of a 64-year-old patient who was treated successfully for pulmonary mucormycosis in Xuan Wu Hospital. The patient presented with low-grade fever and a productive cough that persisted for 1 month with no evident cause, and also suffered from diabetes mellitus. Prior antibiotic treatment with levofloxacin had been ineffective. Culture of mucus obtained by bronchoscopy resulted in a diagnosis of pulmonary mucormycosis...

Two Vietnamese potbellied pigs ( Sus scrofa) had respiratory disease and, on autopsy, both pigs had large masses in the lungs and thoracic cavity. Microscopically, pulmonary and pleural masses contained large areas with hyphae surrounded by hypereosinophilic cellular debris rimmed by abundant eosinophils, lymphocytes, plasma cells, and histiocytes with occasional multinucleate giant cells. The hypereosinophilic debris usually formed tight cuffs, or "sleeves" around the hyphae, compatible with Splendore-Hoeppli-like material...

Tools to diagnose fungal infection are microscopic examination, antigen or antibody-based detection tests, molecular diagnostics, and culture, with culture being the "gold standard" for species-level identification. Although these methods are commonly used in concert and yield concordant results, in some cases tissue is not available for culture, and/or different methodologies yield discrepant results. These discrepancies may be clinically significant, causing confusion and inappropriate or delayed initiation of antifungals...

PURPOSE: The aim of this study was to describe radiological imaging findings of a complicated sinusitis, which should raise the suspicion of rhino-orbital-cerebral mucormycosis as being the underlying cause. METHODS: In this retrospective analysis, we describe the cases and imaging findings of 8 patients with proven mucormycosis. These patients presented mostly with new facial or orbital swelling and were referred for imaging to our institution. Magnetic resonance imaging and computed tomography images were classified as abnormal or normal with respect to orbital, paranasal and cerebral signal results...

Rhinocerebral mucormycosis is an acute, rapidly fatal, fungal infection, classically involving the nasal mucosa and paranasal sinuses. It is an aggressive, opportunistic infection that frequently progresses to involve the orbit and cerebrum. Cerebral extension in immunocompromised patients is almost universally fatal. There are limited data on mucormycosis in pediatric immunocompromised patients in the literature, with only few reports on rhinocerebral involvement. The immunocompromised patients described in this report presented with suspected periorbital and nasal cellulitis, progressing rapidly to necrotic changes in nasal tissue and oral palatal mucosa...

Introduction. Posaconazole is a triazole antifungal that is used in the treatment of a variety of fungal infections, as well as in the management of mucormycosis (on an off-label basis). Eosinophilia associated with exposure to azole antifungals has been described rarely in the literature. Case presentation. A 31-year-old male on peritoneal dialysis (PD) for end-stage renal disease, secondary to diabetic nephropathy, presented to hospital with abdominal pain after a trip to St Lucia. He was taken to the operating room, where the PD catheter was removed and an abdominal-wall abscess was debrided...

Contamination and eutrophication have caused serious ecological events (such as algal bloom) in coastal area. During this ecological process, microbial community structure is critical for algal bloom succession. The diversity and composition of bacteria and archaea communities in algal blooms have been widely investigated; however, those of fungi are poorly understood. To fill this gap, we used pyrosequencing and correlation approaches to assess fungal patterns and associations during a dinoflagellate (Noctiluca scintillans) bloom...

Mucormycosis is a life-threatening invasive fungal disease that affects a variety of patient groups. Although Mucorales are mostly opportunistic pathogens originating from soil or decaying vegetation, there are currently few data on prevalence of this group of fungi in the environment. The aim of the present study was to assess the prevalence and diversity of species of Mucorales from soil samples collected in France. Two grams of soil were homogenized in sterile saline and plated on Sabouraud dextrose agar and RPMI agar supplemented with itraconazole or voriconazole...

Three important strains of Mucorcircinelloides grown in complete and minimal media for specified period (72 h, 120 h and 168 h) under submerged fermentation conditions were investigated for their potential antioxidants/secondary metabolite production. All mycelial extracts demonstrated effective antioxidant activities in terms of β-carotene/linoleic acid bleaching, radical scavenging, reduction of metal ions and chelating abilities against ferrous ions. Different extraction methods and solvent systems affected the recovery yield and antioxidant activities of the extracts significantly (p ≤ 0...

INTRODUCTION: Early diagnosis of acute invasive fungal rhinosinusitis (AIFR) is crucial for patients prognosis and may reduce the extent of surgical debridement. Initial evaluation usually includes paranasal Computed Tomography (CT), with an emphasis on bony erosion which is considered a specific but insensitive radiologic sign. Most studies made no distinction between Aspergillus and Mucor species while addressing CT findings. In this study, we seek to evaluate whether bony erosion on paranasal CT is a significant and reliable finding in the initial evaluation of invasive paranasal mucormycosis...

Pharmaceuticals represent an immense business with increased demand due to intensive livestock raising and an aging human population, which guarantee the quality of human life and well-being. However, the development of removal technologies for these compounds is not keeping pace with the swift increase in their use. Pharmaceuticals constitute a potential risk group of multiclass chemicals of increasing concern since they are extremely frequent in all environments and have started to exhibit negative effects on micro- and macro-fauna as well as on human health...

A 61-year-old man with relapsing chronic lymphocytic leukaemia, status post allogeneic stem cell transplant and multiple chemotherapy regimens presented to the emergency room after suffering a grand mal seizure. His evaluation revealed a 1.5-2 cm ring-enhancing left temporal lobe brain lesion on the CT scan. This brain lesion was resected and the histopathology revealed an invasive fungal organism resembling mucormycosis. Amplification and sequencing of the 28S ribosomal RNA gene identified the organism as Rhizomucor pusillus The patient was treated with liposomal amphotericin B 5 mg/kg every 24 hours for 4 weeks, and then was transitioned to oral posaconazole...

Fungi are organisms capable of growing in a myriad of conditions and respond to counteract environmental cues. Several locations in the world are polluted with oil and its derivatives, and some microorganisms tolerant to these compounds have been isolated. Some fungi can grow in the presence of molecules such as polycyclic aromatic hydrocarbons as sole carbon sources. In this report, we further characterized the induced enzymes with phenanthrene from Mucor circinelloides YR-1 strain, isolated from a polluted field near a petrochemical facility in México...

BACKGROUND AND PURPOSE: Invasive fungal infections cause morbidity and mortality in patients with hematologic malignancies and immunosuppression. Although these infections are commonly caused by Candida and Aspergillus species, infections caused by Mucoralean fungi are also on a growing trend. The definitive diagnosis of mucormycosis includes visualization of non-septate hyphae on pathology or growth of Mucoralean fungi culture. Polymerase chain reaction (PCR) is used to diagnose mucormycosis from paraffin blocks; however, it yields discrepant results in diagnosis of mucormycosis from blood samples...
