Abstract: Epizootic ulcerative syndrome (EUS) is seriously damaging large numbers of commercially important fish species since last two decades. The disease is reported as activate especially from November to February at low ranges of light, temperature and salinity. Red spots, lesions and deep hemorrhagic abrasions were reported commonly on body o...

... under the microscope and observed activeness of fungal motile spores of Aphanomyces sp. (Fig.1). 50 liter volume of water samples were collected from effected habitats strained through plankton net (no. 25, mesh 55µ) that proved the presence of 5 to 7 number of spores and hyphae of Aphanomyces and Alternaria. ...

... However, they differ in morphology; the first lacks sexual structure while the second has smooth walled oogonia. Aphanomyces keratinophilus, A. invadens and an unidentified Aphanomyces species have been previously reported from Pakistan (LILLEY & al. 1998, HUSSAIN & al. 2010, WADAHAR & al. 2012) and this is the first report of A. scaber from Pakistan. Description: Monoecious. ...
This work is part of a biodiversity and biosystematic study of zoosporic fungi of Bajaur, the newly merged district of Khyber Pakhtunkhwa Province. A total of 19 isolates were characterized morphologically and except one all were identified up to species level. Ten species belonged to Saprolegniaceae and one species to each of the Olpidiopsidaceae and Blastocladiaceae. Of these, nine taxa, viz. Brevilegnia minutandra, Leptolegnia caudata, Aphanomyces scaber, Saprolegnia australis, Saprolegnia sp., Achlya orion, Calyptralegnia ripariensis Olpidiopsis saprolegniae var. levis and Allomyces arbusculus, appeared to be new records for Pakistan, Dictyuchus monosporus, Saprolegnia ferax and Achlya bisexualis are reported for the first time for this district. Saprolegnia australis is reported for the first time from a wild freshwater fish, namely Paraschistura alepidota. The fungi are described in detail and illustrated. The rDNA ITS region of 15 isolates was amplified and sequenced. The phylogenetic relationship among the genera of the family Saprolegniaceae is discussed.
