Prevalence and site preferences of heterophyid metacercariae in Tilapia zilli from Ismalia fresh water canal, Egypt.
Factors affecting prevalence and site preferences of heterophyid metacercariae (MC) were investigated in this study. A total of 173 specimens of a freshwater fish, Tilapia zilli were collected during autumn 2008, winter 2009 and summer 2009, from Ismailia fresh water canal, Egypt. Results showed that the total prevalence of heterophyid MC was 95.37%. The heterophyid MC consisted of Haplorchis y...
متن کاملTol2-mediated transgenesis in tilapia (Oreochromis niloticus).
The Nile tilapia (Oreochromis niloticus) is an important species in aquaculture and an excellent model system for laboratory studies. Functional genetic analysis using this species has been difficult because existing methods for producing transgenics are inefficient. Here we show that the Tol2 transposon system can be used to create transgenic tilapia with high efficiency. We constructed a line...
متن کاملInteraction of Francisella asiatica with tilapia (Oreochromis niloticus) innate immunity.
Members of the genus Francisella are facultative intracellular bacteria that cause important diseases in a wide variety of animals worldwide, including humans and fish. Several genes that are important for intramacrophage survival have been identified, including the iglC gene, which is found in the iglABCD operon in the Francisella sp. pathogenicity island (FPI). In the present study, we examin...
متن کاملParasites of the eyes of fresh and brackish water fishes in Iran
In the present investigation a total of six parasite species, some eye-specific and others non-organ specific parasites were found in the eyes of 48 examined fish species, collected from fresh and brackish waters of Iran during 2004-2006. Ichthyophthirius multifiliis was isolated from the external surface of the eyes of Oncorhynchus mykiss, Gyrodactylus stankovici from Cyprinus carpio and Lern...
متن کاملBehaviours Associated with Acoustic Communication in Nile Tilapia (Oreochromis niloticus)
BACKGROUND Sound production is widespread among fishes and accompanies many social interactions. The literature reports twenty-nine cichlid species known to produce sounds during aggressive and courtship displays, but the precise range in behavioural contexts is unclear. This study aims to describe the various Oreochromis niloticus behaviours that are associated with sound production in order t...
