Aspergillus niger is a mold classified within the Nigri section of the Aspergillus genus. [1] The Aspergillus genus consists of common molds found throughout the environment within soil and water, on vegetation, in fecal matter, on decomposing matter, and suspended in the air. [ 2 ]
Aspergillus 235 mags 3X3 copy. Aspergillosis is caused by Aspergillus, a common mold, which tends to affect people who already have a lung disease such as cystic fibrosis or asthma, or who cannot fight infection themselves. [3] The most common causative species is Aspergillus fumigatus. [19]
Aspergillus niger is a prime example of this; it can be found growing on damp walls, as a major component of mildew. [citation needed] Several species of Aspergillus, including A. niger and A. fumigatus, will readily colonise buildings, [7] favouring warm and damp or humid areas such as bathrooms and around window frames.

The maxillary sinus is the most commonly involved. Fungi responsible for fungal sinusitis are Aspergillus fumigatus (90%), Aspergillus flavus, and Aspergillus niger. Fungal sinusitis occurs most commonly in middle-aged populations. Diabetes mellitus is the most common risk factor involved. [3]
There are many factors of oral health which need to be preserved in order to prevent pathogenesis of the oral microbiota or diseases of the mouth. Dental plaque is the material that adheres to the teeth and consists of bacterial cells (mainly S. mutans and S. sanguis ), salivary polymers and bacterial extracellular products.
Aspergillus candidus has been associated with a variety of diseases such as hypersensitivity diseases, and infectious diseases including aspergillosis, otomycosis, and onychomycosis. [2] [11] The dry conidia produced by A. candidus are easily dispersed in air, [9] leading to inhalation by humans and animals. [12]
In humans, A. terreus is less commonly encountered as a pathogen than other Aspergillus species, most notably A. fumigatus, A. flavus and A. niger. [24] [26] Although less frequently seen in clinical samples, A. terreus displays evidence of amphotericin B resistance which correlates to a high rate of dissemination and an overall poor prognosis ...
Aspergillus oryzae [6] Aspergillus sojae [7] Aspergillus niger [8] Amorphotheca resinae [9] Lecanicillium sp. → these produce conidia which may control certain species of insect pests [10] Other entomopathogenic fungi, including Metarhizium and Beauveria spp. Pochonia spp. are under development for control of Nematode pests.
