Microbial (bacterial, algal and fungal) quality of the River Nile water at El-Gharbia governorate
was elucidated during December 2012 - November 2013. Water samples were collected from
mostly polluted sites of twenty four sites at the River Nile of El-Gharbia governorate. Detection
of bacterial indicator count involved total coliform (TC), fecal coliform (FC) and Escherichia
coli (E.coli) revealed increase in summer. Also, some pathogenic bacteria had been detected and
the most frequent were Staphylococcus aureus and E.coli. Algal count was ranging between 54
to 3933 (organisms/ L) and the mostly present algal species were Cyanophyta (Oscillatoria
anguiformis, Nostoc muscorum and Anabaenaconstricta),Chlorophyta (Scenedesmus
brasiliensis and Chlorella vulgaris) and Bacillariophta (Diatoms). Assessment of fungal
contamination in investigated water samples revealed the presence of Aspergillus spp,
Penicillium spp and Fusarium spp and yeasts especially Candida sp during four seasons
especially in summer.
