“…In previous studies, E. faecalis and E. faecium have been reported as the most abundant enterococci isolated from human feces, with a trend of interindividual variation in other enterococci species [18,19,47]. However, in this study, while E. faecalis was detected in a large number of samples, E. faecium was present in only three samples and at a low frequency (4.5-9.1%).…”

Enterococcus spp. are common bacteria present in the intestinal tracts of animals and are used as fecal indicators in aquatic environments. On the other hand, enterococci are also known as opportunistic pathogens. Elucidating their composition in the intestinal tracts of domestic animals can assist in estimating the sources of fecal contamination in aquatic environments. However, information on the species and composition of enterococci in animal hosts (except humans) is still lacking. In this study, enterococci were isolated from the feces of cattle, pigs, birds, and humans using selective media. Enterococcal species were identified using mass spectrometry technology, and each host was characterized by diversity and cluster analysis. The most dominant species were E. hirae in cattle, E. faecium in birds, and E. faecalis in pigs and humans. Cattle had the highest alpha diversity, with high interindividual and livestock farm diversity. The dominant enterococcal species in pigs and humans were identical, and cluster analysis showed that the majority of the two hosts’ species clustered together.

“…Macrolides (tilmicosin and tylosin), tetracyclines (tetracycline), and fluoroquinolones (enrofloxacin) are widely used in pig production in China, which may result in the severe resistance condition for these drugs. Similar to the results of other large-scale investigations in European countries and the United States, rare resistance to tigecycline, linezolid and vancomycin were observed in this study [8,11]. Tigecycline, linezolid and vancomycin are critically important for the treatment of Enterococcus infections and not used in food-producing animals in China.…”

“…The rifampicin resistance phenotypes obtained from the cattle (75%) and sheep (83.3%) isolates were comparable with those found in Tanzanian livestock (63% and 72% rifampicin resistance, respectively) [37][38][39] and Nigeria (90% in horses) [40]. This observation was surprising because this broad spectrum antibiotic was not described in the farms we surveyed.…”

The Antibiotics Used in Livestock and Their Impact on Resistance in Enterococcus faecium and Enterococcus hirae on Farms in Gabon

The emergence of antibiotic resistance is a major concern around the world. The objective of this study was to investigate the antibiotics used in livestock and their impact on resistance in Enterococcus faecium and Enterococcus hirae on farms in Gabon. A structured questionnaire was used to collect information on the farms. Samples were collected from farms (n = 20) tested for Enterococcus by culture and isolation and were identified using a polymerase chain reaction (PCR) and sequencing. Antibiotic susceptibility was determined by the disc diffusion method on Mueller Hinton agar. The 20 farms included laying hens (6), swine (6), sheep (4) and cattle farms (4). Tetracycline was the most used antibiotic family (91%) and the most used prophylactic method (47%) for the treatment of animals. A total of 555 samples were collected and 515 (93%) Enterococcus spp. isolates of the genus were obtained. The prevalence of E. faecium and E. hirae were 10% and 8%, respectively. The isolates from E. faecium and E. hirae we found were related to clinical and human isolates in the NCBI database. E. faecium and E. hirae isolates showed a high resistance to tetracycline (69% and 65%) and rifampicin (39% and 56%). The tet(M) gene was detected in 65 tetracycline-resistant isolates with a large majority in hens (78% (21/27) and 86% (12/14) in E. faecium and E. hirae, respectively). The consumption of antibiotics favours the emergence of antibiotic resistance in animals in Gabon.

Isolation of vancomycin‐resistant Enterococcus from apparently healthy human animal attendants, cattle and cattle wastes in Tanzania

Abstract: The study provides information on the prevalence of VRE in human and nonhuman samples in Tanzania calling for further studies on the origin of VRE in such isolates, since no selection mechanism in Tanzania are known.
