Background： Bacillus spp. seem to be an alternative to antimicrobial growth promoters for improving animals＇ health and performance. However, there is little information on the effect of Bacillus spp. in combination with different dietary crude protein（CP） levels on the ileal digestibility and microbiota composition. Therefore, the objective of this study was to determine the effect of Bacillus spp. supplementation to low-（LP） and high-protein diets（HP） on ileal CP and amino acid（AA） digestibility and intestinal microbiota ***： Eight ileally cannulated pigs with an initial body weight of 28.5 kg were randomly allocated to a rowcolumn design with 8 pigs and 3 periods of 16 d each. The assay diets were based on wheat-barley-soybean meal with two protein levels： LP（14% CP, as-fed） and HP diet（18% CP, as-fed）. The LP and HP diets were supplemented with or without Bacil us spp. at a level of 0.04%（as-fed）. The apparent ileal digestibility（AID） and standardized ileal digestibility（SID） of CP and AA was determined. Bacterial community composition from ileal digesta was analyzed by Illumina amplicon sequencing and quantitative real-time PCR. Data were analyzed as a 2 × 2 factorial design using the GLIMMIX procedures of ***： The supplementation with Bacillus spp. did not affect both AID and SID of CP and AA in growing ***, there was no difference in AID of CP and AA between HP and LP diets, but SID of cystine, glutamic acid,glycine, and proline was lower（P 〈 0.05） in pigs fed the HP diets. The HP diets increased abundance of Bifidobacterium spp. and Lactobacillus spp.,（P 〈 0.05） and by amplicon sequencing the latter was identified as predominant genus in microbiota from HP with Bacillus spp., whereas dietary supplementation of Bacillus spp. increased（P 〈 0.05） abundance of Roseburia ***： The HP diet increased abundance of Lactobacillus spp. and Bifidobacterium spp.. The supplementation of Bacil us spp. resulted in a higher abunda

To evaluate vital signs and body indices in Helicobacter pylori (H. pylori) positive and negative persons. A total of 22 centres entered the study. They were spread over the whole country, corresponding well to the geographical distribution of the Czech population. A total of 1818 subjects (aged 5-98 years) took part in the study, randomly selected out of 38147 subjects. H. pylori infection was investigated by means of a 13C-urea breath test. Data on height, weight, systolic and diastolic blood pressure and heart rate were collected at the clinics of general practitioners. The overall prevalence of H. pylori infection was 30.4% (402/1321) in adults (≥ 18 year-old) and 5.2% (26/497) in children and adolescents (≤ 17 year-old). Once adjusted for age and gender, only a difference in body mass index remained statistically significant with H. pylori positive adults showing an increase of 0.6 kg/m2 in body mass index. Once adjusted for age and gender, we found a difference in height between H. pylori positive and H. pylori negative children and adolescents. On further adjustment for place of residence, this difference became statistically significant, with H. pylori positive children and adolescents being on average 3.5 cm shorter. H. pylori positive adults were significantly older compared to H. pylori negative subjects. Once adjusted for age and gender, H. pylori infection had no impact on body weight, body mass index and vital signs either in adults or children and adolescents. Chronic H. pylori infection appeared to be associated with short stature in children. H. pylori infection did not influence blood pressure, body weight and body mass index either in adults or children and adolescents.
