Immune Response of Nile Tilapia (Oreochromis niloticus) Vaccinated With Diatom‐Based Oral Vaccines Against Piscine Francisellosis

Journal of Fish Diseases, EarlyView.
ABSTRACT Piscine francisellosis is a highly infectious and economically significant disease caused by Francisella orientalis in tilapia (Oreochromis spp.). There are currently no approved treatments or commercial vaccines for this disease in cultured fish.

Modulation of Sodium and Ammonia Transporters in the Context of Viral Gill Diseases in Common Carp (Cyprinus carpio)

Journal of Fish Diseases, EarlyView.
ABSTRACT Osmoregulation and ammonia removal are among key physiological processes that take place in gills and affect fish homeostasis and well‐being. These processes can be disrupted by numerous environmental factors, but also by viral infections, especially those leading to severe gill disorders.

Methylation pattern polymorphism of cyp19a in Nile tilapia and hybrids

Open Life Sciences, 2018
Skewed sex development is prevalent in fish hybrids. However, the histological observation and molecular mechanisms remain elusive. In this study, we showed that the interspecific hybrids of the two fish species, Oreochromis niloticus and Oreochromis ...

Investigating the behavioral responses of nektonic and benthic tadpoles elicited by the presence of a predatory nektonic fish

Journal of Zoology, EarlyView.
Different defensive strategies are used by tadpoles to avoid or escape from predators, and it is possible that differences in the microhabitat of prey and predators influence the defensive strategies used by tadpoles. Therefore, we experimentally tested whether the presence of a nektonic fish predator (Oreochromis niloticus) reduces the time of ...

A novel tilapia prolactin receptor is functionally distinct from its paralog [PDF]

, 2009
A novel tilapia prolactin (PRL) receptor (OmPRLR2) was identified based on its induction during hyperosmotic stress. OmPRLR2 protein shows 28% identity to tilapia OmPRLR1 and 26% identity to human PRLR.
