Trojan horse effect: phagocyte-mediated Streptococcus iniae infection of fish.
The salmonid macrophage-like cell line RTS-11 and purified trout pronephros phagocytes were used to analyze in vitro entry and survival of two Streptococcus iniae serotypes. Efficient invasion by S. iniae occurred in both cells, but only the type II strain persisted in pronephros phagocytes for at least 48 h. Ex vivo models of opsonin-dependent phagocytosis by pronephros phagocytes demonstrated...
متن کاملRecovery of Streptococcus iniae from diseased fish previously vaccinated with a streptococcus vaccine.
Streptococcus iniae was recovered from diseased rainbow trout (Oncorhynchus mykiss, Walbaum) previously vaccinated against streptococcosis. PCR and serological methods indicate the presence of a new serotype in the diseased fish.
متن کاملRetroviruses of wild and cultured fish.
Retroviruses comprise a large group of enveloped RNA viruses which have been found in a wide range of vertebrate species including fish. To date a number of fish retrovirus genomes have been partially or completely sequenced. Phylogenetic analysis and genome organization indicate a high diversity of fish retroviruses as well as some unique structural features that have not been found in any oth...
متن کاملIsolation and molecular identification of Vibrio alginolyticus from cultured marine fish in farms located south provinces of Iran
Bacterial diseases are a major challenge and warning to the development of aquaculture industry. Vibriosis is caused by bacteria of the genus Vibrio, especially Vibrio alginolyticus, in warm and temperate regions, which cause severe damages to the marine fish production economy every year. The aim of the present study was to isolate and identify this bacterium from farmed marine fish with bacte...
متن کاملStreptococcus iniae capsule impairs phagocytic clearance and contributes to virulence in fish.
Surface capsular polysaccharides play a critical role in protecting several pathogenic microbes against innate host defenses during infection. Little is known about virulence mechanisms of the fish pathogen Streptococcus iniae, though indirect evidence suggests that capsule could represent an important factor. The putative S. iniae capsule operon contains a homologue of the cpsD gene, which is ...
