“…However, L. lactis subsp. lactis has been responsible for a 100% loss of hybrid sturgeons (Huso huso × Acipenser ruthenus) in a fish farm in Taiwan, China [31]. In the present study, 31 Enterococcus strains were isolated from skin and kidney samples.…”

Intensive fish farming systems in Brazil have increased the disease incidence, mainly of bacterial origin, due to higher stocking density, high organic matter levels and poor quality of the aquatic environment that causes high mortality rates during outbreaks. The identification of pathogenic species using a fast and reliable method of diagnosis is essential for successful epidemiological studies and disease control. The present study evaluated the use of direct colony PCR in combination with 16S rRNA gene sequencing to diagnose fish bacterial diseases, with the goal of reducing the costs and time necessary for bacterial identification. The method was successful for all 178 isolates tested and produced bands with the same intensity as the standard PCR performed using pure DNA. In conclusion, the genetics methods allowed detecting the most common and important pathogens in Aquaculture, including 12 species of occurrence in Brazilian fish farms. The results of the present study constitute an advance in the available diagnostic methods for bacterial pathogens in fish farms.

“…Recently, Lc. lactis has been isolated from diseased fish (Wang et al, 2008;Chen et al, 2012;Pérez et al, 2011), bovine mastitis cases (Wyder et al, 2011;Romero et al, 2011, Plumed-Ferrer et al, 2013, Werner et al, 2014, bird infections (Goyache et al, 2001), and many human clinical infections (Mofredj et al, 2007;Uchida et al, 2011). Isolates from the genus Lactococcus are often misidentified as enterococci or streptococci, and the difficulties in correctly identifying them have probably hindered elucidation of their clinical significance (Goyache et al, 2001).…”

In total, 181 streptococci-like bacteria isolated from intramammary infections (IMI) were submitted by a veterinary clinic to Quality Milk Production Services (QMPS, Cornell University, Ithaca, NY). The isolates were characterized by sequence analysis, and 46 Lactococcus lactis ssp. lactis and 47 Lactococcus garvieae were tested for susceptibility to 17 antibiotics. No resistant strains were found for β-lactam antibiotics widely used in clinical practice (penicillin, ampicillin, and amoxicillin), and all minimum inhibitory concentrations (MIC) were far from the resistance breakpoints. Eight strains had MIC intermediate to cefazolin. The random amplification of polymorphic DNA (RAPD)-PCR fingerprint patterns showed a slightly higher heterogeneity for Lc. lactis ssp. lactis isolates than for Lc. garvieae isolates.

“…In the case of the endocarditis in allis shad and Lactococcus lactis, the implementation of the required experiments for this purpose was not possible as no specimens of this endangered species were available. Moreover, Lactococcus lactis has already been described as causative agent of infectious diseases of aquatic organisms (Chen et al., ; Wang et al., ) and of endocarditis in humans. Even though human infections with Lactococcus lactis are rare (Facklam & Elliott, ), an infection caused by Lactococcus lactis was first published in 1944 (Wagner, ), while the first report of an endocarditis caused by L. lactis was described in 1955 (Wood, Jacobs, & McCarty, ).…”

“…l actis has been found in the intestinal microbiota of numerous healthy fish (Han et al., ; Itoi et al., , ). Nevertheless, there are two previously published cases of L. lactis infections in aquatic animals, which involved an outbreak of white tail disease in cultured giant freshwater prawn ( Macrobrachium rosenbergii ; Wang, Lin, Liaw, Chern, & Chen, ) and a mass die‐off of Bester sturgeon, a cultured hybrid of Huso huso × Acipenser ruthenus , both in Taiwan (Chen et al., ). However, this is the first report of an endocarditis valvularis and parietalis thromboticans caused by Lactococcus lactis in fish.…”

Since the 1940s, the anadromous allis shad, Alosa alosa (L.), has suffered population declines throughout its distribution range in Europe. In context of EU-LIFE projects for the reintroduction of the allis shad in the Rhine system, a comprehensive study was started in 2012 to investigate infectious diseases occurring in allis shad. In course of the study, 217 mature and young-of-the-year allis shad originating from the wild population from the Gironde-Garonne-Dordogne system (GGD-system) and the Rhine system as well as 38 allis shad from the breeding population were examined by use of bacteriological and histological methods. In 2012 and 2014, an endocarditis valvularis thromboticans caused by a coccoid bacterium was detected in 16% and 25% of mature allis shad originating from the GGD-system. Results of microbiologic examinations, including biochemical characteristics, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and 16S rRNA gene sequence analysis, revealed Lactococcus lactis as causative agent of this infection. This is the first report of an endocarditis valvularis and parietalis thromboticans caused by Lactococcus lactis in fish. Possible sources of infection as well as the impact for the reintroduction programme are discussed.
