“…This is in agreement with the observation of Awad et al that found Aspergillus flavus and Aspergillus niger as the dominant Aspergillus species in urban and rural homes in Egypt (Awad et al, 2013). Similarly, Durugbo et al reported that A. niger was one of the most frequently occurring fungi in air samples from different sites of Redemption City, Nigeria (Durugbo et al, 2013). All in all, our data confirm the ubiquitous nature of the aforementioned genera of fungi in outdoor and indoor samples.…”

Despite the recent increases in fungi-induced allergic diseases, there is no report yet in the region of the Persian Gulf on concentration levels of fungi in relationship with health state. Therefore, our aim was to measure fungi prevalence as well as to evaluate the relationships between air- and dust-borne fungal genera and allergic diseases. A matched case-control study was carried out including 45 allergic cases and 45 age- and gender-matched controls for each individual. Indoor and outdoor dust and indoor air samples were collected from participant homes during May to October 2015. A Quick Take 30 Pump and sterile wet swab were used to determine fungal types and their amounts in the air (CFU/m) and dust (CFU/100 cm) samples, respectively. A significant reverse association was found between indoor dust-borne Alternaria and asthma (Odds ratio (OR) = 0.14, 95% CI = 0.02-0.86). Contrarily, increased levels of indoor air-borne Aspegillus fumigatus (OR = 2.00, 95% CI = 0.37-10.55) and Alternaria (OR = 3.00, 95% CI = 0.34-25.83) were correlated with asthma development. Also, correlation analysis showed a significant relation between indoor air-borne Penicillium levels and reactivity to skin prick test in asthmatic patients (p = 0.04). Our findings support the notion that fungal exposures can either cause or prevent the development of allergic diseases. Accordingly, appropriate measures should be taken for a better management of fungi-induced allergic diseases.

“…Many common infections in both human and animals can spread by airborne transmission (Shams-Ghahfarokhi et al, 2014). Airborne transmission increases the opportunity of human exposure to pathogenic microorganisms during breathing the polluted air or contamination of food and water (Durugbo et al, 2012;Fernstrom & Goldblatt, 2013;Mart‫ם‬nez-Herrera et al, 2016). Airborne fungi is the most important part of human pathogens which cause several human health problems such as allergic, contagious, infectious, and respiratory diseases (Gots et al, 2003).…”

Atya et al. J Pure Appl Microbiol, 13(4), AbstractFungi can cause airborne diseases that need to consider in health plans due to its risk and threats of many communities worldwide. This study aims to assess indoor air quality of laboratory room environment for health industry sector. Open plate method was used to collect and culture of airborne fungi from 12 rooms of laboratories in faculty and hospital buildings. Identification of filamentous fungi grown on culture plates was based on standard mycological texts and manual. The results showed that the occurrence frequency and relative abundance were used to show the risk of airborne fungi. The colony forming unit of fungi species isolated from air samples of faculty and hospital laboratories were 304 and 83 respectively. Thirteen fungi genera including twenty-one species were identified overall air samples. The predominant fungi were Aspergillus, Penicillium and Alternaria among fungi. Among these species the most prevalence fungi was Penicillium chrysogenum at the highest at species level. Therefore, it is essential to set urgent steps to enhance the indoor air quality in laboratory environment such as providing air purification system in these labs.

“…Exposure to bioaerosols is one of the greatest threats to public health because of the adverse effects on humans, animals, and plants [1,2,3]. Bioaerosols are aerial suspensions of particles from living organisms, microorganisms or other biological materials [4,5], the bioaerosols can be dispersed over long distances by air currents and then inhaled, ingested, or otherwise contacted by humans [3].…”

Introduction and objective. Nosocomial invasive fungal infections, particularly aspergillosis, are an increasing problem in immunocompromised patients. The presented study evaluates fungal diversity and the presence of Aspergillus in air samples from two hospitals. Materials and methods. Over the course of one year (rainy and dry seasons), the air was sampled from three areas in two hospitals (1 and 2) using a single-stage Andersen viable particle sampler (Thermo Scientific, Waltham, MA, USA). The fungi were identified by macro-and micromorphology, and the number of colony forming units (CFU)/m 3 air and their richness, abundance, and diversity were determined. Isolates Aspergillus genus were characterized by their thermotolerance. Results. The CFU/m 3 air was similar at both hospitals during the two seasons, but different between the sampled areas. Results showed 10 fungal genera for hospital 1, and 8 for hospital 2. The most abundant were Penicillium, Cladosporium and Aspergillus. The thermotolerance test confirmed the identification of A. fumigatus section Fumigati. The highest growth rate was found in Aspergillus section Nigri. Conclusion. Determining the fungal diversity in the two hospitals was important because all the species have the potential to be pathogenic, especially the section Fumigati.
