Air travel can rapidly transport infectious diseases globally. To facilitate the design of biosensors for infectious organisms in commercial aircraft, we characterized bacterial diversity in aircraft air. Samples from 61aircraft High Efficiency…
-
Objective: To study the changing patterns of antimicrobial resistance in gram negative bacilli esp. E. coli, Klebsiella Pneumoniae, Pseudomonas and Staphylococcus aureus isolates from a 37 bedded ICU of a private hospital. Methods: All isolates…
-
Background: Long-term exposure to a contaminated indoor environment may result in different health complaints. The filamentous fungi indoor air quality assessment of infant and elementary Portuguese schools and Aspergillus sp. identification was…

Colemanite, also called as hydrated calcium borate hydroxide, is a borate mineral found in evaporite deposits of alkaline lacustrins environments. It is a secondary mineral that forms by alternation of borax and ulexite. As this chemical is not…
-
The main objective of this work was the comparative analysis of a large number of bacterial strains isolated from biodeteriorated surfaces in three different sites, namely the catacombs of St. Callistus in Rome, Italy, the catacombs dedicated to St.…
-
Buildings are complex ecosystems that house trillions of microorganisms interacting with each other, with humans and with their environment. Understanding the ecological and evolutionary processes that determine the diversity and composition of the…
-
Exposure to specific airborne bacteria indoors is linked to infectious and noninfectious adverse health outcomes. However, the sources and origins of bacteria suspended in indoor air are not well understood. This study presents evidence for elevated…
-
The main topic of this paper is the study of the qualitative composition of fungal population in some cellar environments: superficial and inner layer of oak barrels, wall surfaces and aging wine. In addition, the influence of age of barrels and…
-
Previous research into microbial persistence on material surfaces following flooding has produced a wide range of results due to differing experimental conditions, including the temperature and humidity conditions of the experimental material and/or…
-
The microbial diversity of different kinds of stains present on the surface of 14 historical documents (nine parchments and five paper letters) was evaluated through a combination of cultural and molecular methods. The samples were recovered using…

The present study was aimed at evaluating the number of bacteria and mould fungi in the indoor and outdoor environment of Toruń University Library. The sampling sites were located in the rooms serving the functions typical of libraries (i.e. in the…
-
Abstract The role of human occupancy as a source of indoor biological aerosols is poorly understood. Size-resolved concentrations of total and biological particles in indoor air were quantified in a classroom under occupied and vacant conditions.…

Health care facility ventilation design greatly affects disease transmission by aerosols. The desire to control infection in hospitals and at the same time to reduce their carbon footprint motivates the use of unconventional solutions for building…
-
Microbially Induced Carbonate Precipitation is proposed as an environmentally friendly method to protect decayed ornamental stone and introduced in the field of preservation of Cultural Heritage. Recent conservation studies performed under…

BACKGROUND: Exposure to house dust endotoxin induces of airways' inflammation. Endotoxin are produced by the Gram-negative bacteria, which are released into the stools and could contaminate domestic environment. OBJECTIVE: The newborn could…
-
Endotoxin may affect the development of allergic disease in childhood but little is known about endotoxin variation within homes. We sought to determine endotoxin concentration agreement within homes when five locations were each sampled twice 5…

Serpula lacrymans, the causative agent of dry rot timber decay in buildings, is a Basidiomycete fungus in the Boletales clade. It owes its destructiveness to a uniquely well-developed capacity to colonize by rapid mycelial spread from sites of…
