Concurrent infections of Streptococcus iniae and Aeromonas veronii in farmed Giant snakehead (Channa micropeltes).

The giant snakehead, Channa micropeltes, is an increasingly important economic freshwater fish in Thailand and other regions of Asia. Presently, giant snakehead are cultured under intensive aquaculture conditions, leading to high stress and conditions favouring disease. In this study, we reported a disease outbreak in farmed giant snakehead with a cumulative mortality of 52.

Pathological Manifestations of in the Green Texas Cichlid ().

() is considered to be one of the major pathogens of tilapia because of the high mortalities observed during outbreaks. Other cichlids belonging to the same family (Cichlidae) as tilapia are also quite susceptible to this pathogen. On various occasions, has also been isolated from other warm water fish, including three-line grunt, hybrid striped bass, French grunt, Caesar grunt, and Indo-Pacific reef fish.

Transcriptome analysis of immune- and iron-related genes after Francisella noatunensis subsp. orientalis infection in Nile tilapia (Oreochromis niloticus).

Francisella noatunensis subsp. orientalis (Fno) is a gram-negative intracellular bacterium identified in many fish species worldwide, including cultured Nile tilapia (Oreochromis niloticus) in Taiwan. To investigate the gene expression responses to Fno infection, we performed transcriptome analysis of the head kidney and spleen in Nile tilapia using RNA-seq.

Comparison of the pathogenicity of Francisella orientalis in Nile tilapia (Oreochromis niloticus), Asian seabass (Lates calcarifer) and largemouth bass (Micropterus salmoides) through experimental intraperitoneal infection.

Francisella orientalis is a highly virulent, emerging bacterium that causes mass mortalities in tilapia. This pathogen also affects numerous other warm-water fish species, including three-line grunt, hybrid striped bass and various ornamental fish. This study sheds light on two new species of fish that are susceptible to F.

Immune Responses and Protective Efficacy of a Formalin-Killed Subsp. Vaccine Evaluated through Intraperitoneal and Immersion Challenge Methods in .

subsp. (), an intracellular bacterium, causes systemic granulomatous diseases, resulting in high mortality and huge economic losses in Taiwanese tilapia farming. In this study, we tested the efficacy of a formalin-killed vaccine in cultured tilapia.

Molecular characterization and pathogenicity of Francisella noatunensis subsp. orientalis isolated from cultured tilapia (Oreochromis sp.) in Taiwan.

Francisella noatunensis subsp. orientalis is a causative agent of systemic granulomatous disease in tilapia. The present study was designed to understand the genetic and phenotypic diversities among Taiwanese Fno isolates obtained from tilapia (n = 17) and green Texas cichlid (Herichthys cyanoguttatus) (n = 1).
