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 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...
متن کاملA Microwave-Irradiated Streptococcus agalactiae Vaccine Provides Partial Protection against Experimental Challenge in Nile Tilapia, Oreochromis niloticus
Microwave irradiation, as opposed to formalin exposure, has not routinely been used in the preparation of killed vaccines despite the advantages of decreased chemical toxicity, ability to kill cells quickly, ease of completion requiring only a standard microwave, and potential increased protein conservation during irradiation. We evaluated the potential of microwave irradiation versus formalin ...
متن کاملWhole genome shotgun sequencing of Indian strains of Streptococcus agalactiae
Group B streptococcus is known as a leading cause of neonatal infections in developing countries. The present study describes the whole genome shotgun sequences of four Group B Streptococcus (GBS) isolates. Molecular data on clonality is lacking for GBS in India. The present genome report will add important information on the scarce genome data of GBS and will help in deriving comparative genom...
متن کاملAntigenicity of Streptococcus agalactiae extracellular products and vaccine efficacy.
Streptococcus agalactiae is a major bacterial pathogen that is the cause of serious economic losses in many species of freshwater, marine and estuarine fish worldwide. A highly efficacious S. agalactiae vaccine was developed using extracellular products (ECP) and formalin-killed whole cells of S. agalactiae. The vaccine efficacy following storage of S. agalactiae ECP and formalin-killed S. agal...
