“…In the study by Göttlich et al [44], the harmful aquatic fungal species Aspergillus fumigatus was isolated from patients who were suffering from immunosuppression infections and organ failure. The confirmation of the pathogenic fungi in patients was conducted by comparing the genotypes of the species and the genotype of a microorganism isolated from the patient [4,45]. …”

“…This has prompted water utilities, stakeholders in water issues and all other sectors that are responsible for the supply and distribution of drinking water to come up with strategies to protect consumers from waterborne diseases, as well as to ensure that the water that reaches the public does not harbor any pathogenic microorganisms. According to the few available reports, the monitoring of microbial pathogens in most drinking water systems is dependent on the monitoring of indicator microorganisms (bacteria), especially measures of the total coliforms and Escherichia coli [2,3,4,5]. However, in reality, coliforms by themselves may not necessarily be a health hazard, but act as an indicator for the presence of pollution in water systems.…”

Currently, there is a worldwide growing interest in the occurrence and diversity of fungi and their secondary metabolites in aquatic systems, especially concerning their role in water quality and human health. However, this concern is hampered by the scant information that is available in the literature about aquatic fungi and how they affect water quality. There are only few published reports that link certain species of aquatic fungi to human health. The common aquatic fungal species that have been reported so far in African aquatic systems belong to the hyphomycetes kingdom. This paper thus aims to survey the information about the occurrence and factors that control the distribution of different species of fungi in African aquatic systems, as well as their effect on water quality and the possible metabolic pathways that lead to the formation of toxic secondary metabolites that are responsible for the deterioration of water quality. This review will also investigate the analytical and bioanalytical procedures that have been reported for the identification of different species of waterborne fungi and their secondary metabolites.

“…Fungi in water distribution systems are well known and have gained importance recently [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]. It is unsurprising that fungi are isolated from the surface or underground raw water in reservoirs and distribution systems [8,16,17,18] since they are found in almost every environmental niche.…”

Filamentous fungi in drinking water distribution systems are known to (a) block water pipes; (b) cause organoleptic biodeterioration; (c) act as pathogens or allergens and (d) cause mycotoxin contamination. Yeasts might also cause problems. This study describes the occurrence of several fungal species in a water distribution system supplied by groundwater in Recife—Pernambuco, Brazil. Water samples were collected from four sampling sites from which fungi were recovered by membrane filtration. The numbers in all sampling sites ranged from 5 to 207 colony forming units (CFU)/100 mL with a mean value of 53 CFU/100 mL. In total, 859 isolates were identified morphologically, with Aspergillus and Penicillium the most representative genera (37% and 25% respectively), followed by Trichoderma and Fusarium (9% each), Curvularia (5%) and finally the species Pestalotiopsis karstenii (2%). Ramichloridium and Leptodontium were isolated and are black yeasts, a group that include emergent pathogens. The drinking water system in Recife may play a role in fungal dissemination, including opportunistic pathogens.

C. & Parkin, 2007. In the same way, improved protocols for an efficient isolation of DNA from water for detection and monitoring of plant pathogens have been reported (Pereira et al, 2010).…”
