| parasitic relationships between pythium oligandrum drechsler and some other species of the oomycetes class. | parasitic relationships between pythium oligandrum drechsler and some phytopathogenic species of the oomycetes class were investigated on agar plates. a high parasitic ability of pythium oligandrum on pythium ultimum trow, p. debaryanum hesse, and aphanomyces laevis de by species was proved in this study of relationships among these fungi, commonly populating the rhizosphere of emerging sugar beet. p. oligandrum produces numerous thin haustorial threads, searching the hyphae of host species and ... | 1978 | 726706 |
| fungal diseases of fish in nanak sagar, naini tal, india. | eight zoosporic fungi viz., achlya debaryana, a. flagellata, a. klebsiana, aphanomyces laevis, saprolegnia diclina, s. ferax, s. parasitica, and pythium sp. were isolated from a large number of adult fishes of the species mastacembelus armatus, mystus vitatus, nandus nandus, tor putitora and t. tor of nanak sagar reservoir in naini tal district, india. species of the parasites and the hosts were different in their pathogenicity and immunity, respectively. however, a. flagellata and s. parasitica ... | 1995 | 7566059 |
| a fatal oomycotic disease of the fresh water fish aplocheilus panchax in india caused by aphanomyces laevis. | the fish, aplocheilus panchax (hamilton-buchanan, 1839), is recorded as a new host of aphanomyces laevis de bary, 1860. it is the first and only report of any oomycete causing disease on a. panchax. aphanomyces laevis was found to be a virulent parasite of a. panchax that caused cotton-wool disease involving the skin and fins. the hyphae also penetrated deep into the tissues of the infected fish and all of them ultimately died. | 2002 | 12041867 |
| distribution of zoosporic fungi in the mud of major egyptian lakes. | twenty-six identified and three unidentified species belonging to eight genera of zoosporic fungi were recovered from seventy-six mud samples of egyptian lakes using sesame seeds as baits. nineteen samples were collected along the borders of four major lakes. pythium, phytophthora and allomyces, yielded the highest spectra of zoosporic species, while aqualinderella, blastocladia and dictyuchus, had one species. pythium, aphanomyces, allomyces, aqualinderella, phytophthora and saprolegnia were th ... | 2003 | 12761768 |
| [water fungi occurence in the river supraśl-bath jurowce near białystok]. | studies on the occurrence of aquatic fungi in the bathing sites of the supraśl river in jurowce village were collected in years 2000-2003. hydrochemical analysis was performed using standard methods. bait method was used to isolate the fungi. in the supraśl river at jurowce village 36 fungi species were identified, among them fish pathogens achlya orion, aphanomyces laevis, dictyuchus monosporus, saprolegnia ferax, saprolegnia monoica, s. parasitica, human pathogens aspergillus flavus, candida a ... | 2004 | 16859017 |
| [water fungi occurence in the water reservoir in zarzeczany of podlasie province]. | studies on the occurrence of aquatic microorganisms in the newest water reservoir zarzeczany village were carried out in years 2001-2004. hydro chemical analysis was performed using standard methods. bait method was used to isolate the fungi. in the reservoir 52 fungi species were identified: fish pathogenic achlya debaryana, a. polyandra, aphanomyces laevis, dictyuchus monosporus, d. sterile, saprolegnia ferax, s. monoica, s. parasitica, human pathogenic candida albicans, c. tropicalis and tric ... | 2004 | 16865972 |
| larvicidal activity of the fungus aphanomyces (oomycetes : saprolegniales) against culex quinquefasciatus. | several species of fungi are currently being considered for operational use in the microbial control of mosquito larvae. the oomycetous fungi are the prominent ones amongst them because of their ability to complete life cycle in water. during our studies on zoosporic fungi from riverine waters of mula and mutha flowing through pune city, maharashtra, india, aphanomyces laevis de bary (oomycetes: saprolegniales) was isolated from polluted waters. after critical observations it was found to be mos ... | 2005 | 17278656 |
| genotoxicity of two pathogenic strains of zoosporic fungi (achlya klebsiana and aphanomyces laevis) on erythrocytes of nile tilapia oreochromis niloticus niloticus. | in the present work we have described the genotoxic potential of two pathogenic strains of zoosporic fungi (achlya klebsiana and aphanomyces laevis) on erythrocytes of nile tilapia oreochromis niloticus niloticus for the first time by three complementary tests: micronucleus test (mn), nuclear lesions (nl) and comet assay (ca). the groups exposed to the zoosporic fungi subjected to the mn and nl test showed statistically significant differences in mn and nl frequencies with respect to the control ... | 2010 | 19811832 |
| pathogenicity and oxidative stress in nile tilapia caused by aphanomyces laevis and phoma herbarum isolated from farmed fish. | identified (n = 17) and unidentified (n = 1) fish-pathogenic fungal species from 10 genera of oomycetes and soil fungi were isolated from 40 infected freshwater fish samples of the species oreochromis niloticus niloticus (nile tilapia) and clarias gariepinus (african catfish). samples were collected from various fish farms in the nile delta, egypt. nile tilapia were tested in aquaria for their susceptibility to the commonest oomycetes species, aphanomyces laevis and achlya klebsiana, and also ag ... | 2011 | 21553565 |
| Occurrence of fungi and fungus-like organisms in the Horodnianka River in the vicinity of Bialystok, Poland. | Studies of fungi and fungus- like organisms in the northeastern Poland have mainly concentrated on running waters in the vicinity of Bialystok, including the Horodnianka River. The main objective was to investigate biodiversity of fungi and fungus-like organisms which take part in decomposition of organic matter commonly found in inland waters. To obtain a complete picture of species composition of fungi and fungus-like organisms in running waters we decided to explore representative sites of th ... | 2011 | 22165737 |
