Human Streptococcus agalactiae Isolate in Nile Tilapia (Oreochromis niloticus)
Streptococcus agalactiae, the Lancefield group B streptococcus (GBS) long recognized as a mammalian pathogen, is an emerging concern with regard to fish. We show that a GBS serotype Ia multilocus sequence type ST-7 isolate from a clinical case of human neonatal meningitis caused disease and death in Nile tilapia (Oreochromis niloticus).
متن کاملEfficacy of a Streptococcus iniae modified bacterin delivered using OraljectTM technology in Nile tilapia (Oreochromis niloticus)
This study evaluated the potential to orally deliver a previously developed Streptococcus iniae vaccine in tilapia using OraljectTM technology. This technology was developed to administer bioactive compounds to monogastric animals, and has been shown to be effective for delivery of a variety of antigens in numerous fish species. Two different formulations containing two doses of vaccine (four t...
متن کاملStreptococcus iniae outbreaks in Brazilian Nile tilapia (Oreochromis niloticus L:) farms
This is the first report of outbreaks of Streptococcus iniae in Nile tilapia farms in South America. Seven isolates were identified by biochemical, serological and molecular tests. Their 16S rRNA gene sequences showed 100% similarity with S. iniae ATCC 29178 and two distinct PFGE patterns were observed for Brazilian isolates.
متن کاملDraft Genome Sequences of Streptococcus agalactiae Strains Isolated from Nile Tilapia (Oreochromis niloticus) Farms in Thailand
During 2009-2011, two clinical and one environmental strains of Streptococcus agalactiae were isolated from Nile tilapia (Oreochromis niloticus) farms in Thailand. Draft genome sequences of two clinical isolates comprise 2,048,343 and 2,105,006 bp, while environmental isolates comprise 2,097,115 bp, having 1,573 to 1,578 coding sequences, respectively.
متن کاملFecal Strings Associated with Streptococcus agalactiae Infection in Nile Tilapia, Oreochromis niloticus
This study provides the first description of long fecal strings in Streptococcus agalactiae-infected fish. Nile tilapia (Oreochromis niloticus) were administered an intraperitoneal injection with 0.1 mL solution containing a 10-fold dilution from 10 1 to 10 6 cfu S. agalactiae/fish. While infected fish developed clinical signs commonly associated with S. agalactiae infection, up to 40% of infec...
