Enterococcus faecalis involved in streptococcosis like infection in silver barb (Barbonymus gonionotus)

Virulence and antibiotic-resistance genes in Enterococcus faecalis associated with streptococcosis disease in fish

“…Among these, streptococcosis is one of the vital diseases in tilapia caused by a complex group of bacteria including Streptococcus iniae, S. agalactiae , Lactococcus garviae , Vagococcus salmoninarum and Enterococcus spp. 5 , 8 , 9 . The first pathogenic Enterococcus sp.…”

“…Morita, et al 11 detected L. garvieae as the causal agent of septicemic fatal hemorrhagic disease in fish. Recently, pathogenic Enterococcus faecalis were diagnosed from streptococcosis like infection in Nile tilapia in Egypt, India and Bangladesh 12 – 14 and in silver barb ( Barbonymus gonionotus ) in Bangladesh 8 . Like Streptococcus, E. faecalis is a Gram-positive, cocci belong to the family Enterococcaceae that causes disease in animals, and humans.…”

“…E. faecalis (i.e. strains BFPS1, BFPS3, BFPS6 and BFPS13) were also identified from streptococcosis infected silver barb ( B. gonionotus ) fish 8 . Among the strains mentioned earlier, BFFF11, BFF1B1 and BFPS6 appears to be more pathogenic, hence, these three strains were focused in the current study.…”

Suppression of Streptococcosis and Modulation of the Gut Bacteriome in Nile Tilapia (Oreochromis niloticus) by the Marine Sediment Bacteria Bacillus haynesii and Advenella mimigardefordensis

“… Streptococcus iniae , S. agalactiae , S. parauberis , and S. dysgalactiae are recognized as the prominent causative agents of streptococcosis in different geographical regions ( 13 – 16 ). In addition, Lactococcus garvieae , Vagococcus sp., Enterococcus faecalis , E. faecium , and E. hirae have also been reported as notable causative agents of streptococcosis in Asian countries such as India ( 17 ), Bangladesh ( 10 , 11 , 18 ), Philippines ( 19 ), and Indonesia ( 20 ) as well as an African country, Egypt ( 21 , 22 ). Enterococci were previously classified as streptococci of Lancefield group D ( 23 ).…”

“…Enterococcus sp. has also been reported as a pathogen in many fish species such as Japanese yellow tail ( Seriola quinqueradiata ) ( 24 ), turbot ( Scophthalmus maximus ) ( 25 ), walking catfish ( Clarias batrachus ) ( 10 ), stinging catfish ( Heteropneustes fossilis ) ( 10 ), silver barb ( Barbonymus gonionotus ) ( 18 ), red tilapia ( Oreochromis hybrid) ( 20 ), and flathead gray mullet ( Mugil cephalus ) ( 26 ).…”
