The antibacterial effects of a combination of Coptidis rhizoma and Galla rhois extracts (CGE) were evaluated in piglets. The minimum bactericidal concentration of CGE was 2.0 mg/mL. Thirty 5-week-old piglets were challenged with Campylobacter (C.) coli after allocation to three different groups, a control and two treatment groups fed with CGE at 2.0 or 4.0 g/kg feed for 7 days. On day 7, C. coli in the feces of the CGE-treated groups were significantly lower than in the control (p < 0.01). These results suggest that CGE can be used to control C. coli in piglets.

Background: PCR technique combined with culture isolates is used commonly to detect bacteria that can cause diarrhea from clinical samples. Direct DNA extraction which is a simple, fast and effective method is very important in the rapid diagnosis of bacterial pathogens from fecal samples. Objective: Perfection of method for direct DNA extraction of Shigella and EIEC from fecal samples. Subjects and method: EIEC ATCC 43893, E. coli ATCC 11775 was used for positive and negative controls. Extracted DNA would be used for PCR. Results: The method for direct DNA extraction of Shigella and EIEC from fecal sample had been successfully developed. It was a simple, rapid, cheap and applicable method. Conclusion: The method for direct Shigella/EIEC DNA extraction had been successfully developed and it was very helpful in early detection of diarrheal-induced bacterial pathogens.

Of total 1125 diarrheal fecal samples examined. There were 163 specimens positive by using PRC (14.5%), and 67 Shigella found by culture (5.9%). The positive samples have been characterized by mucus, blood and leukocytes. The results showed that 49% of positive cases by PCR, and 61% of the positive cases by culture had mucus/blood or mucus or blood in the stool. Meanwhile, 18% positive cases by PCR, and 11.9% of positive cases by culture had no mucus, blood and leukocytes in the stool. Together with clinical signs, mucous, bloody and leukocyte characteristics in the stool was useful tools for clinicians in the diagnosis of shigellosis.

DNA pyrosequencing, one of the advanced methods for DNA sequencing, has been employed for phylogenetic analysis of bacterial communities using the conserved 16S rRNA gene. We performed a pilot study on a mother-neonate pair utilizing the DNA pyrosequencing assays to investigate the diversity of microbial communities in maternal amniotic fluid (AF), vagina, and rectum and newborn gastric fluid (GF) and stool. Phylum level analysis revealed that bacterial community was dominated by Firmicutes (63.2%) in maternal feces, and Actinobacteria (84.9%) in maternal vaginal swab. The bacterial communities in both the AF and GF were dominated by Proteobacteria (67.8%). Interestingly, the bacterial community in the newborn's meconium was quite similar to that in the AF. However, the composition of the bacterial community in newborn's feces was different on day 14 and dominated by Firmicutes (91.1%). Genus-level analysis revealed that the bacterial community in maternal feces was dominated by Anaerococcus (19.5%) and Prevotella (18.7%), whereas that in the maternal vaginal swab was dominated by Atopobium (83.6%). The bacterial communities in both the AF and GF were dominated by Sphingomonas (38.5%). The bacterial community in the newborn's meconium was quite similar to that in the AF, which was dominated by Sphingomonas (45.2%). However, the composition of bacterial community in the newborn's feces on day 14 was relatively different. Future studies with a large number of infants are needed to determine the factors involved in the changing profile of newborn's fecal bacterial communities.

This study was conducted to obtain accurate data on the intake, digestibility and nitrogen balance of protein in Korean college women. Subjects were 8 female college students, aged from 21 to 23, and maintained their menu and life patterns regular during a 4-week study. The same amount of diet that the subjects had consumed, and feces and urine were collected and measured to extract their nitrogen content by Kjeldahl method. From this data, apparent digestibility and the body nitrogen balance were estimated by determing daily protein intake and excretion. The daily protein intake was 56.9+/-1.4g and daily fecal protein loss was 6.3+/-0.2g. The apparent digestibility of protein was 89.6+/-0.7%. The daily nitrogen intake measured by Kjeldahl method was 9.43+/-0.2g. The urinary nitrogen excretion was 7.64+/-0.23g and fecal nitrogen excretion was 1.02+/-0.03g. The nitrogen balance indicated a positive balance of 0.45+/-0.18g.

In this study, the food intake, feces and urine of 14 primary school age boys and girls were collected and intake and excretion of iron and zinc were measured. The boys and girls were 8-12 years old and measurement continued for four weeks during which they maintained their normal living pattern. Each boy's and girl's daily intake and excretion of iron and zinc were measured and apparent digestibility and balance were also calculated. The results are as follows. Mean daily intake of iron was 14.9+/-0.6 mg for the boys and 12.4+/-0.5 mg for the girls. Mean daily intake of zinc was 11.8+/-1.2 mg for the boys and 11.5+/-0.4 mg for the girls. Mean daily fecal loss and apparent digestibility of iron was 6.1+/-0.3 mg and 58.8+/-2.0% for the boys and 6.8+/-0.1 mg and 44.1+/-2.0% for the girls. Mean daily fecal loss and apparent digestibility of zinc was 9.3+/-0.2 mg and 14.4+/-5.1% for the boys and 9.7+/-0.4 mg and 14.3+/-4.3% for the girls. Mean daily urinary loss of iron was 1.1+/-0.1 mg and showed the positive balance of 7.86+/-0.6 mg for the boys and 0.5+/-0.1 mg and showed the positive balance of 5.14+/-0.4 mg for the girls. Mean daily urinary loss of zinc was 0.5+/-0.1 mg and showed the positive balance of 1.03+/-0.6 mg for the girls.

Intestinal microbial ecosystem is the most complex and the largest micro-ecosystem of the mammals. The use of antibiotics can lead to a lot of major changes of the flora, making the intestinal flora damaged and impacted, even developing Clostridium difficile infection. Fecal microbiota transplantation (FMT) as a special organ transplant therapy, which can rebuild the intestinal flora, has raised the clinical concerns. It has been used in the refractory Clostridium difficile, inflammatory bowel disease, irritable bowel syndrome, chronic fatigue syndrome, and some non-intestinal diseases related to the metabolic disorders. But this method of treatment has not become a normal treatment, and many clinicians and patients can not accept it. This paper reviews relevant literature in terms of origin, indications, mechanism, production process, current situation and future research, and provide a reference for the clinical application of the treatment of fecal microbiota transplantation.

Eggerthella lenta is an anaerobic, non-spore-forming, non-motile, gram-positive bacillus that can be isolated from human feces and a few other clinical specimens. Bacteremia caused by the organism is rare but, when present, is always of clinical significance. E. lenta is an emerging pathogen that has been under-recognized because of difficulties with its laboratory identification. Few reports on E. lenta infections and the optimal treatment thereof are available. We describe a case of bacteremia caused by E. lenta in an elderly patient with an intra-abdominal abscess. We also review the current literature.

Colorectal fecaloma is a mass of accumulated feces that is much harder in consistency than a fecal impactation. The rectosigmoid area is the common site for fecalomas and the cecum is the most unusual site. Diagnosis is usually made by distinctive radiographic findings of a mobile intraluminal mass with a smooth outline and no mucosal attachment. Most of the fecalomas are successfully treated by conservative methods such as laxatives, enemas and rectal evacuation. When conservative treatments have failed, endoscopic procedures or a surgical intervention may be needed. We report here that a cecal fecaloma caused by intestinal tuberculosis scar was successfully removed by endoscopic procedures.
