The association of Lactococcus petauri with lactococcosis is older than expected

open access: yesAquaculture
Lactococcosis is a globally prevalent infectious disease that has a significant economic and sanitary impact on the rainbow trout industry. Lactococcus garvieae has traditionally been considered the only species implicated in the etiology of this disease, but Lactococcus petauri, a new species, has recently been implicated as another etiological agent.

Use of a probiotic to control lactococcosis and streptococcosis in rainbow trout, Oncorhynchus mykiss (Walbaum)

Journal of Fish Diseases, 2005
AbstractFrom a comparison of 125 bacterial isolates recovered from the digestive tract of rainbow trout, Oncorhynchus mykiss, and carp, Cyprinus sp., a culture was obtained which was effective at preventing clinical disease caused by Lactococcus garvieae and Streptococcus iniae when used as a feed additive.

Current knowledge of lactococcosis in rainbow trout: Pathogenesis, immune response and prevention tools

open access: yesAquaculture
La lactococcose causée par Lactococcus garvieae est devenue l'une des maladies bactériennes les plus dévastatrices affectant la truite arc-en-ciel (Oncorhynchus mykiss) dans le monde. Comprendre la réponse immunitaire à cet agent pathogène streptococcique est crucial pour diagnostiquer et gérer la maladie associée et pour développer des vaccins et des ...

Preliminary characterization of Lactococcus garvieae bacteriophage isolated from wastewater as a potential agent for biological control of lactococcosis in aquaculture

Aquaculture International, 2014
Lactococcosis, a significant emerging disease of fish caused by Lactococcus garvieae, has become one of the devastating problems due to its serious economic damage in aquaculture. The aim of this study was to isolate and characterize a lytic phage infecting L. garvieae as a potential bioagent for the treatment of lactococcosis.

Use of adjuvanted vaccines to lengthen the protection against lactococcosis in rainbow trout (Oncorhynchus mykiss)

Aquaculture, 2006
In this work, we evaluated the effect of the inclusion of different adjuvants in the vaccine formulation against Lactococcus garvieae in comparison with an aqueous bacterin. The aqueous and non mineral oil adjuvanted vaccines (Montanide-ISA-763-A and Aquamun) yielded a good protection 4 weeks after the immunization (RPS of 82.6, 84.8 and 86.9 ...

Immunomodulatory effects of orally administrated florfenicol in rainbow trout (Oncorhynchus mykiss) following experimental challenge with streptococcosis/lactococcosis

International Immunopharmacology, 2019
The purpose of the present work was to determine whether florfenicol (FFC) as the prominent broad-spectrum antibiotic could affect serum biochemical and immunological parameters, as well as immune-related genes expression in rainbow trout (55 ± 7.6 g) challenged with the Lactococcus garvieae and Streptococcus iniae. In the first trial, the doses of the

Lactococcus garvieae outbreaks in Brazilian farms Lactococcosis in Pseudoplatystoma sp. – development of an autogenous vaccine as a control strategy

Journal of Fish Diseases, 2016
AbstractThis study evaluated the control of streptococcosis outbreaks in Brazil, isolated from diseased sorubim and identified as Lactococcus garvieae by genetic sequencing. This report determined the potential for lactococcosis control in sorubim Pseudoplatystoma sp. with two vaccines: an aqueous‐based, whole‐cell inactivated vaccine (bacterin) and an
