ABSTRACT Concerns about antibiotic-resistant bacteria and their presence in animal products grow and thus alternatives to use of antibiotics in animal production are being investigated. Probiotics have gained increased focus due to improvements in performance, immune health and pathogen reduction when provided to poultry through feed. These traits may be further improved if probiotics can be provided to the embryo before hatch, before meeting environmental pathogens. The objective was to determine the faith of a probiotic Enterococcus faecium (M74) strain in the yolk sac and intestinal tract of broiler chickens after injection into hatching eggs. E. faecium M74 (1.4 × 107 CFU/egg) was applied in ovo at day 18 of incubation. From 1- and 7-day-old chickens, 20 samples from yolk sac, caecal tonsils and rest of the intestinal tract were subjected to CFU counting. Isolates from a sample subset were typed by pulsed-field gel electrophoresis (PFGE). Enterococci were found in varying numbers: 1.0 × 104–2.2 × 1010 CFU/g. The prevalence of M74 PFGE profiles was high in 1-day-old (88%) and 7-day-old chickens (67%). This demonstrates that the embryos ingested M74 before hatching, that M74 is viable for intestinal colonization through in ovo administration, and that the strain multiplies in the chickens gastrointestinal tract post hatching.

ABSTRACT Fecal samples from humans and food-producing animals were analyzed for the presence of vancomycin-resistant enterococci (VRE). The VRE carriage rate in humans was 6%, and there was a predominance of VanC-type resistance. Enterococcus faecium with vanA-mediated resistance was frequent in broiler chickens (42%) but rare in cattle and pig samples.

ABSTRACT The extent of transfer of antimicrobial resistance from agricultural environments to humans is controversial. To assess the potential hazard posed by streptogramin use in food animals, this study evaluated the effect of virginiamycin exposure on antimicrobial resistance in Enterococcus faecium recovered from treated broilers. Four consecutive broiler feeding trials were conducted using animals raised on common litter. In the first three trials, one group of birds was fed virginiamycin continuously in feed at 20 g/ton, and a second group served as the nontreated control. In the fourth trial, antimicrobial-free feed was given to both groups. Fecal samples were cultured 1 day after chickens hatched and then at 1, 3, 5, and 7 weeks of age. Isolates from each time point were tested for susceptibility to a panel of different antimicrobials. Quinupristin/dalfopristin-resistant E. faecium appeared after 5 weeks of treatment in trial 1 and within 7 days of trials 2 to 4. Following removal of virginiamycin in trial 4, no resistant isolates were detected after 5 weeks. PCR failed to detect vat, vgb, or erm(B) in any of the streptogramin-resistant E. faecium isolates, whereas the msr(C) gene was detected in 97% of resistant isolates. In an experimental setting using broiler chickens, continuous virginiamycin exposure was required to maintain a stable streptogramin-resistant population of E. faecium in the animals. The bases of resistance could not be explained by known genetic determinants.

AbstractIt was postulated that administration of a probiotic to chickens can stimulate their antioxidant status while at the same time inhibiting oxidation processes. The objective of the study was to determine whether and how different levels and durations of application of a probiotic preparation containing live cultures of Enterococcus faecium and enriched with cholecalciferol and ascorbic acid influences indicators of lipid status and the redox reaction in the blood of broiler chickens. Four hundred day-old Ross 308 chickens were raised until their 42nd day of age. The animals were assigned to five experimental groups of 80 broilers each: a control group that did not receive the probiotic, T1 groups, which received the probiotic at 0.25 (E-0.25) or 0.1 g/l (E-0.1) throughout the rearing period, and T2 groups, which received the probiotic at the same levels, but during days 1–7, 15–21 and 29–35 of life. The probiotic preparation reduced the level of peroxides (LOH), malondialdehyde (MDA), cholesterol (TC), low density (LDL) cholesterol, and non-esterified fatty acids (NEFA), and the activity of catalase (CAT), gamma-glutamyltransferase (GGT), acid phosphatase (AC), alkaline phosphatase (ALP) and 3-hydroxybutyrate dehydrogenase (HBDH), while ferric reducing ability of plasma (FRAP) and glutathione (GSH + GSSG) levels were increased in the blood plasma of the chickens. The results obtained indicate that administration of this probiotic to chickens, especially in the amount of 0.25 g/l for the entire rearing period, stimulates synthesis of low-molecular-weight antioxidants responsible for maintaining redox homeostasis, without exerting a negative effect on liver metabolism in chickens.
