“…All the test isolates and the enterococci control strains were negative when reacted with the A antiserum. This observation is in agreement with the report that Lancefield's groups D and G are specific for the genus Enterococcus while groups A, B, C, E and F belong to the genus Streptococcus (Facklam, 2002;Kohler, 2007).…”

In South Africa, individuals who reside in most rural areas do not have access to portable water and they rely on untreated water from boreholes. This exposes them to disease causing microorganisms. The aim of the study was to isolate and determine the antibiotic susceptibility profiles of enterococcus in ground water from three rural communities in the Mmabatho area, North-West Province of South Africa. Enterococcus selective agar (ESA) was used for selective isolation of Enterococci species. The identities of the isolates were determined using preliminary (Gram staining, catalase test, oxidase test) and confirmatory (API 20 Strep and the Prolex TM Streptococcal Grouping Rapid Latex Agglutination test kit) test. Two hundred and twenty five presumptive isolates were screened and 139 were positively identified. Three enterococcus species were identified; Enterococcus faecium (71.2%), Enterococcus faecalis (23.0%) and Enterococcus avium (5.8%). A large proportion of the isolates (73.4%) belonged to the Lands field group D serotype when compared to the G group (26.6%). A large proportion of the isolates (75 to 100%) from Ramosadi and Seweding were resistant to vancomycin, penicillin G, erythromycin, chloramphenicol, oxytetracycline, amoxycilin and sulphamethoxazole. Isolates from Mothlabeng showed little resistance against these drugs. The identification of vancomycin-resistant enterococci was a cause for concern since they pose a severe challenge to the medical profession. The natural hosts of E. faecium and E. faecalis are humans and animals. From these results, it is proposed that the isolates could have originated from contamination of these water sources with faeces since most of the boreholes are constructed near the pit toilets.

“…Die grampositiven, katalasenegativen Enterokokken wurden früher zu den fä-kalen Streptokokken gezählt, jedoch seit 1984 als eigene Gattung Enterococcus geführt [1,2]. Von den mittlerweile über 35 bekannten Enterokokkenspezies haben Enterococcus (E.) faecalis und E. faecium die größte klinische Bedeutung und gehören als Besiedler des Intestinaltraktes zur normalen Darmflora von Mensch und Tier.…”

“…In this study, the antimicrobials active isolates were obtained from traditional Egyptian food (Koskos) and were identified as Enterococcus hirae. Enterococcus a member of the lactic acid bacteria (LAB) that is found in various environments and are also found in vegetables, plant materials and fermented foods products (Giraffa, 2002;Koehler, 2007;Elsilk et al, 2015). MRS, pH 6.5, temperature 30 º C and incubation period of 20 hours were the optimum condition for the production of bacteriocin indicated that this medium was the most convenient and contains specific nutrients that are required for the production of a desired material (Ogunshe et al, 2007).…”

“…Enterococcus, a member genus of the lactic acid bacteria (LAB) is found in various environments, but more particularly in the intestines of humans and other animals, also it is found in vegetables like-plant materials and fermented foods products (Giraffa, 2002;Koehler, 2007;Helena et al, 2014). Bacteriocins are extremely heterogeneous group of antibacterial substances.…”

The isolated organisms are screened for their antimicrobial activities against different microbial indicators. These activities expressed in inhibition zones against all tested indicator organisms. PCR products used to assess the DNA similarities and multiple sequences showed 92% identity to Enterococcus hirae (accession no.HM584102). Further identification to species level, E. hirae was based on pigment and carbohydrate formation.
