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 کاملMetacercarial Infection of Wild Nile Tilapia (Oreochromis niloticus) from Brazil
Fingerlings of Oreochromis niloticus collected in an artificial urban lake from Belo Horizonte, Minas Gerais, Brazil, were evaluated for natural infection with trematodes. Morphological taxonomic identification of four fluke species was performed in O. niloticus examined, and the total prevalence of metacercariae was 60.7% (37/61). Centrocestus formosanus, a heterophyid found in the gills, was ...
متن کاملPassive immunization of Nile tilapia (Oreochromis niloticus) provides significant protection against Streptococcus agalactiae.
A study was conducted to determine the role of specific antibodies in immunity to Streptococcus agalactiae. Adult Nile tilapia (Oreochromis niloticus) were injected i.p. with tryptic soy broth as control or with S. agalactiae vaccine. Ninety days later, fish were challenged with 1.5x10(4)CFUS. agalactiae fish(-1). Blood was drawn from all fish 90d after vaccination and 25d after challenge, and ...
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 کاملVisual communication stimulates reproduction in Nile tilapia, Oreochromis niloticus (L.).
Reproductive fish behavior is affected by male-female interactions that stimulate physiological responses such as hormonal release and gonad development. During male-female interactions, visual and chemical communication can modulate fish reproduction. The aim of the present study was to test the effect of visual and chemical male-female interaction on the gonad development and reproductive beh...
