High Efficacy of the Volatile Organic Compounds of Streptomyces yanglinensis 3-10 in Suppression of Aspergillus Contamination on Peanut Kernels

In conclusion, our results indicate that S. yanglinensis 3-10 may has a potential to become a promising biofumigant in for control of A. flavus and A. parasiticus.

Abstract Invasive pulmonary aspergillosis (IPA) remains difficult to diagnose and to treat. Most common risk factors are prolonged neutropenia, hematopoietic stem cell or solid organ transplantation, inherited or acquired immunodeficiency, administration of steroids or other immunosuppressive agents including monoclonal antibodies and new small molecules used for cancer therapy. Critically ill patients are also at high risk of IPA. Clinical signs are unspecific. Early computed tomography (CT)-scan identifies the two main aspects, angioinvasive and airway invasive aspergillosis. Although CT-scan findings are not fu...

Publication date: Available online 22 January 2020Source: Journal de Mycologie MédicaleAuthor(s): Arghadip Samaddar, Anuradha Sharma, Twishi ShrimaliAbstractAcrophialophora fusispora is a soil-borne fungus rarely implicated in human infections. Here, we report a case of pulmonary infection due to A. fusispora in a 59-year-old male who presented with productive cough and gradually progressive dyspnoea for 20 days. He had a past history of pulmonary tuberculosis and was a known case of chronic obstructive pulmonary disease for past five years. He was diagnosed with mixed connective tissue disease and had been receivin...

A 78-year-old female diagnosed with myelodysplastic syndrome excess blasts-2 ten months ago was admitted to our hospital due to fever and a tender, 3-cm purple-red infiltrative erythema on her right lower leg. This single lesion evolved into multiple lesions with a sporotrichoid pattern over four days (Fig. 1a). Laboratory data revealed white blood cell count of 400/ μL. A computed tomography scan revealed a halo sign in the upper lobe of her right lung (Fig. 1b). Biopsies of the lung and lower leg were performed, and the histological examination showed mycelium of Aspergillus species (Fig.

We report an unusual case of a patient with persistent cough and dyspnoea in the context of prior chemoradiotherapy for primary lung cancer who was subsequently found to have invasive tracheobronchial aspergillosis of the distal trachea and proximal of right main bronchus. Invasive tracheobronchial aspergillosis is a rare disease with most reported cases in the literature occurring in immunocompromised hosts. We report an unusual case of a patient with persistent cough and dyspnoea in the context of prior chemoradiotherapy for primary lung cancer. Chest computed tomography (CT) demonstrated an abnormal soft tissue mass sur...

CONCLUSIONS: Our case highlights the relevance of microbiological studies in patients with osteomyelitis and the involvement of soft tissue. The FDG-PET/CT scan was found to be a useful tool for revealing the extent of the disease and evaluating the response to the antifungal therapy. PMID: 31128846 [PubMed - as supplied by publisher]

Conclusion: This prospective multicenter study provides information on the current incidence and outcome of IFD in the real life setting. Practice variation between the centers may help to ultimately improve antifungal management in children at highest risk for IFDs. Introduction Available data on the incidence and outcome of invasive fungal diseases (IFD) in children treated for a hematological malignancy or undergoing allogeneic hematopoietic stem cell transplantation (HSCT) are mostly based on single site, retrospective studies or on studies performed prior to the availability of newer compounds such as broad-sp...

In this study they also showed PTX3 localized in NETs formed after neutrophil activation (5). Proteomics analysis revealed that PTX3 forms complexes with two anti-microbial proteins [azurocidin (AZU1) and myeloperoxidase (MPO)] associated to NETs (30). More recently, PTX3 localization in NETs has been confirmed, and the colocalization with AZU1 and MPO has been defined more accurately (31). Further investigation will be needed to understand the involvement of PTX3 interaction with AZU1 and MPO in their antibacterial role during NET formation. Regulation of Complement Activation PTX3 interaction with microorganisms is not...

We report a case of Paragonimus westermani infection simultaneously affecting two separate organs that presented as both a pulmonary cavity and adrenal mass in an immunocompromised host.A 65-year-old male with a previous kidney transplant visited our clinic because of hemoptysis. Forty-three months earlier, bilateral spontaneous pneumothorax was diagnosed and treated with oxygen supplementation and right chest tube insertion. At that time, there was no demonstrable cavitary lesion in either lung and no mass in the adrenal glands (Fig. 1A, 1B). Computed tomography (CT) of the chest when the patient presented with hemoptysis...
