In 2016 and 2017, we characterized outbreaks caused by Streptococcus agalactiae serotype III sequence type (ST) 283 in Nile tilapia farms Brazil. Whole-genome multilocus typing clustered the fish isolates together with zoonotic ST283 other STs related to cases humans, frogs, dogs, cattle, dolphins.
Streptococcosis caused by Streptococcus agalactiae (S. agalactiae) is a major bacterial disease affecting the production of Nile tilapia (Oreochromis niloticus L.), causing significant economic losses due to mortality in growing phase. Vaccination most effective method for preventing streptococcosis on farms. In Brazil, tilapia-producing regions have long cycles (6–10 months) and harvest tilapias weighing over 900 g fillet production. Thus, data duration humoral immune response protection...
West Nile virus (WNV) is a neurovirulent mosquito-borne Flavivirus that maintained in nature by zoonotic transmissioncycle between avian hosts and ornithophilic mosquito vectors, mostly from the Culex genus. Until 1990s, WNV wasconsidered to be an old-world arbovirus, but 1999, emerged United States (US) spread rapidly, becoming amajor threat public health. adapted transmission cycle involving American mosquitoes birds reachedCentral South America subsequent years. In 2003, National Fever...
The infectious spleen and kidney necrosis virus (ISKNV) is one of the most important emerging viral pathogens for Nile tilapia (Oreochromis niloticus) farming. While prevalent worldwide, it has recently been detected in Brazil. However, despite importance affected fish species, there are no scientific data on effects water temperature disease pathogenesis tilapia. In present study, we conducted two trials using juvenile over a 15-day period. trial 1, an experimental infection model was...
Streptococcus agalactiae is an important pathogen responsible for cases of high mortality in farmed and wild fish worldwide. In Brazil, this bacterium has been commonly associated with outbreaks Nile tilapia farms, but other native species are also susceptible. Since floating cages one the most common culture systems used country, close contact between presents a risk concerning transmission pathogen. study, we characterized outbreak free-living trahira arapaima, as well genetic...
