Sampling campaigns indoors have shown that occupants exposed to contaminated air generally exhibit diverse health outcomes. This study intends assess the deposition rates of total settleable dust and bioburden in indoor dwellings onto quartz fiber filters electrostatic collectors (EDCs), respectively. EDC extracts were inoculated malt extract agar (MEA) dichloran glycerol (DG18) agar-based medi...

The aim of this study is to determine the fungal species in the toothbrushes of residents of a neighborhood on the east side of Teresina - PI, and to assess the efficiency of a disinfection method based on 2% sodium hypochlorite. Fifty toothbrushes were divided into two groups: group A comprised 30 toothbrushes used by the residents and group B (control group) 20 new toothbrushes. Fungal evalua...

No studies have evaluated the efficacy of culturing cerebrospinal fluid (CSF) for fungi. Because of the facts that the most common fungi responsible for meningitis grow well in media utilized for routine bacterial cultures and that cryptococcal antigen tests are commonly ordered, the efficacy of routinely performing fungal cultures specifically to recover fungi has been questioned. We examined ...

Human fungal infections have gained recent notoriety following contamination of pharmaceuticals in the compounding process. Such invasive infections are a more serious global problem, especially for immunocompromised patients. While superficial fungal infections are common and generally curable, invasive fungal infections are often life-threatening and much harder to diagnose and treat. Despite...

BACKGROUND Microbial corneal infection is the most serious complication of contact lens wear. Contact lens cases are a recognised potential source of pathogens associated with corneal ulcers. METHODS This survey established the incidence of protozoal, bacterial, and fungal contact lens case contamination in 101 asymptomatic daily wear cosmetic contact lens wearers from a domiciliary contact l...

This work aimed to analyze the nutrient values, examine the biodeteriorating fungi biota, and analyze the mycotoxin contents of "Suya spices." Fungi with highest percentage occurrence on all the samples are Aspergillus niger, Aspergillus flavus, Aspergillus parasiticus, Aspergillus ochraceus, Fusarium sp., Rhizopus stolonifer, yeast, and Trichoderma koningii. Nutrient composition of the samples...

Fungal meningitis transmitted through injections of methylprednisolone contaminated with Exserohilum rostratum affected 753 persons and caused 61 deaths in the United States in 2012. We report a case of infection recurrence after 24-months with the unique manifestation of an intradural fungal abscess. Fungal disease should remain on the differential diagnosis list for previously exposed patients.

Sensitive molecular methods, such as the PCR, can detect low-level contamination, and careful technique is required to reduce the impact of contaminants. Yet, some assays that are designed to detect high copy-number target sequences appear to be impossible to perform without contamination, and frequently, personnel or laboratory environment are held responsible as the source. This complicates d...

Aflatoxin contamination is a major economic and food safety concern for the peanut industry that largely could be mitigated by genetic resistance. To screen peanut for aflatoxin resistance, ten genotypes were infected with a green fluorescent protein (GFP)-expressing Aspergillus flavus strain. Percentages of fungal infected area and fungal GFP signal intensity were documented by visual ratings ...
