“…In humans, Sullivan, Barkholt and Nord () demonstrated the capacity of dietary probiotic supplementation in preventing ecological disturbances during the antibiotic therapy. In the original definition as proposed by Fuller (), probiotics exerted their effect by improving the intestinal microbial balance of the host. The non‐pathogenic Bacillus species of Gram‐positive bacteria have been studied and used as additives for their capacity of sporulation in poultry rearing (Griggs & Jacob, ).…”

The purpose of this study was to verify the ability of a probiotic in the feed to maintain the stability of the gut microbiota in chickens after antibiotic therapy and its association with growth performance. One thousand six hundred twenty 1‐day‐old Cobb male were housed in floor pens (36 pens, 45 birds/pen) and were fed corn‐/soya bean meal‐based diets supplemented with or without probiotic (Bacillus subtilis) during the entire rearing phase. From 21 to 24 days of age (three consecutive days), the chickens were submitted to antibiotic therapy via drinking water (bacitracin and neomycin) in order to mimic a field treatment and induce dysbiosis. Growth performance was monitored until 42 days of age. At 2, 4 and 6 days after antibiotic therapy, three chickens from each pen were euthanized and the contents of the small intestine and caeca were collected and pooled. The trial was conducted with four treatments and nine replicates in a 2 × 2 factorial arrangement for performance characteristics (with and without probiotic × with and without antibiotic therapy); for the intestinal microbiota, it was in a 2 × 2 × 3 factorial arrangement (with and without probiotic × with and without antibiotic therapy × 2, 4 and 6 days after the antibiotic therapy) with three replicates per treatment. Terminal restriction length polymorphism (T‐RFLP) analysis showed that the structure of gut bacterial community was shaped by the intestinal segment and by the time after the antibiotic therapy. The number of 16S rDNAs copies in caecum contents decreased with time after the therapeutic treatment. The antibiotic therapy and dietary probiotic supplementation decreased richness and diversity indexes in the caecal contents. The improved performance observed in birds supplemented with probiotic may be related to changes promoted by the feed additive in the structure of the intestinal bacterial communities and phylogenetic groups. Antibiotic therapy modified the bacterial structure, but did not cause loss of broiler performance.

“…However, among these germs, the major agents of collective food poisoning such as Salmonella, etc can be noted (Messens et al, 2005). It should be noted that the presence of pathogenic materials on egg shell may be dangerous to the consumers because the egg contamination is reported to be either horizontal or vertical (Fuller, 1984;Bouedo et al, 1993;Gabriel et al, 2005). The different types of Table 5.…”

The aim of this study was to investigate the microbial quality of eggs produced by informal farms and sold in most Abidjan's markets. Thus, a preliminary investigation was conducted to evaluate the frequency of eggs consumption by the population of the study area (Abidjan). After this investigation, an analysis of the eggs microbiological quality was performed both on the shell and the eatable (egg yolk) part. The eggs were categorized into two groups: i-eggs with shell covered with droppings and iieggs with shell not covered with droppings. Four samples of eggs were randomly taken in the same batch collected from 10 districts of Abidjan. Therefore, a total of 90 samples of each category were taken for microbial analyses. The classical method of enumeration in food bacteriology was used for the research of total aerobic mesophilic flora, Enterococcus, total and fecal coliforms, Enterobacteriaceae, the golden Staphylococcus and sulphite-reducing anaerobic bacteria. The present study data show that the consummation of eggs varies according to the area. None of the eatable part contained the investigated bacteria. In general, bacterial counts were higher on shells covered with droppings. Total aerobic mesophilic counts of ~5x10 7 CFU/g vs. 10 5 CFU/g was observed on not covered samples. Similarly, Enterococci, Enterobacteriaceae and Staphylococcus reached ~10 4 CFU/g on shells covered with dropping, about 1 log higher than the values observed for non-covered shells. This study suggests that the contamination of the eggs by the investigated microbial parameter is mainly observed on the shell and not on the eatable part. Also, the highest contamination levels were observed in eggs with dropping on the shells.

“…Diet can alter the gut microflora (Adams, 1980;Hungate, 1984;Stutz and Lawton, 1984), whereas overgrowth of certain bacterial species has been implicated in growth depression in chickens (Fuller, 1984). Wagner and Thomas (1978) observed a significant increase in the intestinal (Key words: pentosans, arabinoxylan, chicken, necrotic enteritis, Clostridium perfringens) anaerobes when rye rather than corn was fed to chicks.…”

“…Microbial population fluctuations occur with age in chickens (Barnes et al, 1972;Fuller, 1984) and strict anaerobes predominate in the hindgut microflora of chickens (Salanitro et al, 1978). Diet can alter the gut microflora (Adams, 1980;Hungate, 1984;Stutz and Lawton, 1984), whereas overgrowth of certain bacterial species has been implicated in growth depression in chickens (Fuller, 1984).…”

The Effects of Nonautoclaved and Autoclaved Water-Soluble Wheat Extracts on the Growth of Clostridium perfringens

et al. 1996

Clostridium perfringens is the causative agent of necrotic enteritis, a commonly diagnosed disease in chickens that is also observed in turkeys and geese. Two trials were conducted to determine the in vitro effect of filter-sterilized, water-soluble wheat extracts on the growth of C. perfringens. The extracts were either nonautoclaved or autoclaved at 121 C for 40 min and were used to reconstitute thioglycolate broth media. Results of this study suggest that growth of C. perfringens is suppressed in vitro by inclusion of either extract. Glycosyl composition analysis revealed no significant differences in arabinose, xylose, or mannose content between the nonautoclaved and autoclaved extracts. Galactose, glucose, and total glycosyl content were significantly higher in the nonautoclaved extract.
