Differences in specificity, development time and virulence between two acanthocephalan parasites, infecting two cryptic species of Gammarus fossarum by Bauer, Alexandre, Develay Nguyen, Lucie, Motreuil, Sébastien, Teixeira, Maria, Debrosse, Nelly, Rigaud, Thierry

“…In this work, the respective roles of parasites species (P. laevis and, for the first time, P. tereticollis) and sympatric host cryptic species (the G. fossarum species complex) were studied experimentally on two traits: host susceptibility to infection and parasite virulence. Differences were found, both in terms of infectivity and virulence, between the cryptic hosts and between the two parasite species. …”

Bacterial Quality and Molecular Detection of Food Poisoning Virulence Genes Isolated from Nasser Lake Fish, Aswan, Egypt by Nady Khairy Elbarbary, Mohamed K. Dandrawy, Ghada Hadad, Maha Abdelhaseib, Amna A. A. Osman, Rawaf Alenazy, Ibrahim Elbagory, Neveen M. Abdelmotilib, Fagelnour Elnoamany, Ghada A. Ibrahim, Reda A. Gomaa

“…Two hundred and fifty fish samples, including 50 of each Oreochromis niloticus, Sander lucioperca, Lates niloticus, Clarias gariepinus, and Mormyrus kannume, from Nasser Lake, Aswan, Egypt, were collected to detect the bacterial load, isolation, and identification of Aeromonas hydrophila, Pseudomonas aeruginosa, and Vibrio parahaemolyticus and their virulence genes. The findings revealed that Oreochromis niloticus and Clarias gariepinus exhibited higher bacterial loads than other fish species. …”
