Abstract
Pathogenic fungi of drinking water have potentially prevailing effects on human beings. Mycofloral study of drinking water of district Bhimber, Azad Kashmir was conducted through systematic sampling and temporally during the year 2009. Drinking water samples were collected from selected spots and fungal spores were grown on two different culture media viz: potato dextrose agar (PDA) and nutrient agar (NA) and identified by employing Direct Plate method (DPM) and Baiting Technique (BT). A total of 4 resources of drinking water of the area were analyzed i.e., well, spring, hand pump and tap water (water supply system). Sixteen different fungal species were frequently prevailing in the analyzed samples and among these five species were predominantly found human pathogenic. The density of identified fungal species in well’s water samples (WWS) was 11 spp. spring’s water samples (SWS) 6 spp. hand pump water samples (HWS) 8 spp. and tap water samples (TWS) 7 spp. This differential incidence in the samples might be due to variation in geography, edaphalogy, altitude, temperature, in fungal growth substrate variance and analytical difference of sampling and analysis methods. The prevalence values of mycolfora in different samples were variable with WWS Mucor fragilis (18a~LSD), SWS Brevilegnia sp. (20a~LSD), HWS Aspergillus flavus (14a~LSD) and TWS Alternaria alternata (12a~LSD). It was noted that WWS more frequently depicted mycoflora because land/well provides best environment and nourishment for growth and reproduction of fungi. The economic importance and pathogenic toxicity of various species is also measured and documented in the article.
