Pan‐Asian spread of single fungal clone results in large scale fish kills

Phylogenetic relationships among plant and animal parasites, and saprotrophs in Aphanomyces (Oomycetes)

“…The names thus far given to pathogenic Aphanomyces isolates obtained from diseased fish having epizootic ulcerative syndrome, EUS, i.e., A. piscicida (Hatai, 1980), A. invaderis , and, ultimately, A. invadans reflect individual author preferences, geographic location, and the evolved conclusion that these names actually describe the same organism based on phenotypic and biochemical characteristics, and finally, molecular genotype. The fact that Callinan et al (1995) and Lilley et al (1997) confirmed the same organism as the causative agent of EUS, redspot disease (RSD) in Australia, and mycotic granulomatosis (MG) in Japan, in a variety of fish species would appear to give the name selected by these authors, i.e., A. invadans, primacy. In the most recent World Organisation for Animal Health (Office International des Epizooties former) manual, the 'Case definition' section identifies both names (A. piscicida and A. invadans) as equivalent.…”

The immune response of rainbow trout (Oncorhynchus mykiss) againstAphanomyces invadans

“…The aetiological agent of EUS is Aphanomyces invadans (also called A. invaderis and A. piscicida), an oomycete fungus that has spread across Asia causing outbreaks of the disease in many areas from Japan and Australia, westwards to Pakistan (Lilley et al, 1997a). The disease a#ects fish from inland waterways and rice fields, as well as fish in culture ponds.…”

“…It has recently occurred in Pakistan (Lilley et al, 1997a). As a final note, the fact that rainbow trout are, to some extent, susceptible to the disease has significant implications for the fish farming industry in Europe, especially with regard to the rate at which the disease is spreading.…”

Isolation and characterization of virulent Aeromonas veronii from ascitic fluid of oscar Astronotus ocellatus showing signs of infectious dropsy

“…They are responsible for motile aeromonad septicaemia (MAS) and bacterial haemorrhagic septicaemia (BHS) and are associated with epizootic ulcerative syndrome in numerous freshwater (Rahman et al 2004, Shao et al 2004) and marine species (Lilley et al 1997).…”
