  • Purpose: The aim of this study was to analyze the effects of probiotics and zinc supplements on the mean duration and frequency of acute diarrhea in children aged 6 months to 2 years. Methods: In this clinical trial of infants aged between 6 months and 2 years, eligible patients were divided into 3 groups: Zinc Receiving Group (ZRG), Probiotic Receiving Group (PRG), and a control group receiving supportive care alone. The frequency of diarrhea was evaluated in the test groups during the first 24 hours and 48-72 hours, along with the duration of hospitalization and diarrhea persistence for 3-7 days. Results: Diarrhea persisted for until the third day of admission in 100% of the infants in PRG compared with only 76.1% in ZRG. The relative risk of diarrhea persistence in the PRG was 1.31 times more than in ZRG until the third day. Also, 80% of diarrhea cases in the PRG persisted until the fourth day of admission, compared with 47.8% in the ZRG group, and this value was significant. The relative incidence of diarrhea persistence in the PRG was 36.4 times greater than in the ZRG until the day 4. Also, the percentage of post-treatment complications was 35.5% in the PRG and 2.6% in the ZRG, which was significant. Conclusion: In our study, the effectiveness of zinc at a dose of 20 mg was higher than that of probiotics. The complications associated with zinc supplementation were lower than those of probiotics.

  • Clostridium difficile-associated disease (CDAD) is an important nosocomial infectious diarrhea and is associated with antibiotic use. Recently, incidence of C. difficile has been increasing in hospitals. A total of 1,329 stool specimens were examined from January, 2005 to December, 2008. This study analyzed the incidence and clinical characteristics of C. difficile infections on them. Out of 1,329 stool specimens, 283 specimens showed toxin A/B positive, using EIA. The positive rate was 21.2%; with the highest incidence among and above the 70years old. On endoscopy, psedo membranous colitis was found in 57.7%, and 19.5% of patients were normal. Pathologic finding showed PMC in 26.8% of patients, AAC in 52.2%. C. difficile was associated with PMC, however, endoscopic and pathologic findings tests showed normal to PMC.

  • Clostridium difficile infection (CDI) is a rapidly emerging infection that may have devastating consequences. Prompt and accurate diagnosis is crucial for management and control. The aim of this study was to determine the incidence of C. difficile associated diarrhea among hospitalized patients, and to compare different diagnostic laboratory methods for detection of toxin producing strains in clinical specimens. The study was conducted at a university hospital in Cairo during the period from May 2013 till June 2015. Subjects were under antibiotic therapy and presented with hospital-acquired diarrhea. Four hundred and sixty-five stool specimens were processed by different microbiological methods. C. difficile was recovered in culture in 51 of stool specimens. Of these, 86.3% to 98% were positive for toxin production by 2 different methods. This study showed that antibiotic intake is the major risk factor for development of hospital-acquired diarrhea. We evaluated different microbiological methods for diagnosis of C. difficile. We recommend the use of toxigenic culture as a gold standard for microbiological diagnosis of C. difficile.

  • This study investigated the effects of tannic acid (TA) in the diets for weanling pigs prepared with/without supplemental Fe on performance, hematology, fecal microflora and diarrhea incidence. Limestone and calcium phosphate used in Experiment 1 and 2 were of semi-synthetic and feed-grade quality, respectively; while the trace-mineral premix used in both the experiments was prepared without any added Fe source. In Experiment 1, 108 weaned pigs (Landrace ${\times}$ Yorkshire ${\times}$ Duroc, initially 6.46 ${\pm}$ 1.04 kg BW) were allotted to 3 treatments including control (diet added with $FeSO_4$ and antibiotic), T1 (diet devoid of $FeSO_4$ and antibiotic) and T2 (T1 diet added with 125 mg/kg TA). Each treatment had 4 replicates with 9 pigs in each pen. Feeding of T1 diet had a negative effect on the performance and plasma Fe status of pigs, while addition of TA to T1 diet resulted in performance of pigs comparable to pigs fed the control diet, reduced diarrhea incidence but had a negative influence on the hematological and plasma Fe indices. Additionally, pigs fed T2 diet had fewer (p<0.05) total anaerobic bacteria, Clostridium spp. and coliforms than pigs fed T1 diet, and greater number of Bifidobacterium spp. and Lactobacillus spp. in feces when compared with pigs fed control and T1 diets. In Experiment 2, 144 weaned pigs (Landrace ${\times}$ Yorkshire ${\times}$ Duroc, initially 6.00 ${\pm}$ 1.07 kg BW) were allotted to 4 dietary treatments including control (diet added with $FeSO_4$ and antibiotic) and diets devoid of supplemental Fe added with antibiotic (An), TA and both (AnTA). Each treatment had 4 replicates with 9 pigs in each pen. Addition of An, TA or both to diets devoid of supplemental Fe did not have any effect on performance, blood hematology and plasma Fe but resulted in reduced (p<0.05) diarrhea incidence and lower (p<0.05) fecal coliform population than pigs fed the control diet. These results suggest that TA has a negative influence on blood hematology and plasma Fe status when diets are inadequate in Fe; however, TA reduced diarrhea incidence and might have antimicrobial activity.

  • The prevalence of diarrhea caused by enterotoxigenic Escherichia coli was surveyed on 445 calves in 6 farms which were located in the central part of Korea. The incidence of enterotoxigenic Escherichia coli in calves with diarrhea was investigated by detecting the K99 and F41 antigens from the isolated strains of Escherichia coli The incidence of colibacillosis in calves was 23.3%. Of 238 strains of Escherichia coli isolated from calves with diarrhea, 73 strains(30.6%) were proved possessing the K99 antigen by mannose-resistant hemagglutination(MRHA) using horse red blood cells and 79(33.1%) possessing F41 antigens by MRHA using guinea-pig red blood cells. The minca medium, nutrient broth, tryptic soy broth and brain heart infusion were tested for yield of K99 and F41 pili. The production of pili was greatest in minea medium. The best detachment method of the K99 and F41 pili from the cells was heat treatment for 20 minutes at $60^{\circ}C$ and concentration by precipitation with ammonium sulfate. The purified antigens of K99 and F41 were polypeptides with molecular weights of 18,500 and 29,500, respectively by sodium dodecyl sulfate-polyacrylamide gel electrophoresis.

  • A study investigated the effects of a mixture of Lactobacillus plantarum (L. plantarum) and Bacillus subtilis (B. subtilis) on diarrhea incidence, immune response, and fecal microflora counts in post-weaning piglets. One hundred 28-day-old piglets were randomly assigned to five treatment groups: negative control (NC), free of antibiotics; positive control (PC), 0.03% chlortetracycline; LB 1, a mixture of L. plantarum and B. subtilis (LB) 0.5 kg/ton feed; LB 2, LB 1.0 kg/ton feed; and LB 3, LB 2.0 kg/ton feed. Diarrhea scores for LB 2 and LB 3 from the 2nd week were significantly reduced compared to NC (P<0.05). In terms of the level of IgG and IFN-${\gamma}$, all treatment groups were significantly higher than NC (P<0.05), and the IgG level of LB 3 was significantly higher than that of PC (P<0.05). Furthermore, fecal lactic acid bacteria (LAB) counts for LB 2 and LB 3 were significantly higher than those of NC and PC (P<0.05). In addition, fecal Enterobacteriaceae (ENT) counts for PC, LB 2 and LB 3 were significantly lower than those of NC (P<0.05). Based on the results from this study, it was concluded that a combination of L. plantarum and B. subtilis strains could be used as potential alternatives to antibiotics to prevent diarrhea incidence in piglets.

  • In most cases, acute diarrhea in childhood heals spontaneously, but it may become the form of chronic diarrhea in immunodeficient children and then cause weight loss, dehydration, malabsorption and malnutrition. The immunodeficient diseases associated with chronic diarrhea include severe combined immunodeficiency syndrome, common variable immunodeficiency, acquired immunodeficiency syndrome, agammaglobulinemia or selective IgA deficiency. IgA deficiency is the most common primary immunodeficiency. Because many IgA deficient individuals seem to have compensated for their deficiency with increased IgM production and various nonimmunologic factors, the incidence of gastrointestinal involvement is not prominent. Some of those with IgA deficiency and recurrent infections have been found to also have IgG subclass deficiency. IgA deficiency with $IgG_2$ and $IgG_4$ subclass deficiency have high susceptability to infection and chronic diarrhea. IgG subclass deficiency, when present, is more likely to be found in association with a partial IgA deficiency rather than complete IgA deficiency. We report a 3-month-old male with intractable diarrhea accompanied by IgA, $IgG_2$, and $IgG_4$ deficiency.

  • The objective of this study was to determine the effect of feeding direct-fed microbials (DFM) on the growth performance and prophylaxis of calf diarrhea during the pre-weaning period as an alternative to antibiotics. A multi-species DFM was formulated including three lactic acid bacteria (Lactobacillus salivarius Ls29, Pediococcus acidilactia Pa175, and L. plantarum Lp177), three Bacillus strains (B. subtilis T4, B. polymyxa T1 and SM2), one yeast, Saccharomyces boulardii, and a nonpathogenic E. coli Nissle 1917. Lactic acid bacteria and Bacillus strains were selected based on the antibacterial activity against various animal pathogens, especially pathogenic E. coli using agar diffusion methods in vitro. Test and control groups were fed milk replacer and calf starter supplemented with DFM ($10^9$ cfu each of eight species/d/head, n = 29) or with antibiotics (0.1% neomycin sulfate in milk replacer and Colistin 0.08% and Oxyneo 110/110 0.1% in calf starter, n = 15), respectively. Overall fecal score and the incidence rate of diarrhea were reduced in the DFM group compared to the antibiotics one. About 40% of calves in antibiotic group suffered from diarrhea while in DFM group only 14% showed diarrhea. There was no difference in the average daily gain and feed efficiency of two groups. The hematological levels of calves were all within the normal range with no significant difference. In conclusion, the feeding of multispecies DFM during the pre-weaning period could reduce calf diarrhea and there was no difference in the growth performance between the groups, thus showing the potential as an alternative to antibiotics.

  • In this presented study, we established a method for diagnosis of porcine epidemic diarrhea(PED) by in situ hybridization(ISH), which made distinct progress in diagnostic pathology. We also carried out the retrospective diagnosis through ISH to assume the exact time of the first outbreak and incidence of PED in Korea. The outbreak of PED in Korea reported in 1992. However, since the end of 1980's, some researches of pig-industry have already suspected the outbreak of PED, not transmissible gastroenteritis(TGE). In this experiment, we performed the ISH using 80 formalin-fixed and paraffin-embedded tissues of porcine intestine which were requests for pathological diagnosis from 63 farms whose primary sign was diarrhea from 1984 to 1991. We prepared biotinylated cDNA probe(492base pairs) for ISH by nick translation method and carried out the ISH, using $Microprobe^{TM}$ capillary action system(Fisher $Biotech^R$). We detected PED virus in intestinal mucosa of 2 cases in 1992, 1 case in 1988, and 1 case in 1987. As a result, we assume that the outbreak of PED in Korea have already started since 1987.

  • Microorganisms causing bovine mastitis, swine diarrhea and swine pneumonia were isolated from farms in Chungbuk and Kyunggi Province and the isolates were identified using microbial identification system(MIS). The most common isolates from bovine mastitis were Staphylococcus sp.,Streptococcus sp., and Corynebacterium sp., those from swine diarrhea were Escherichia coli, Salmonella sp., and Clostridium perfringens, those from swine pneumonia were Bordetella bronchiseptica and Pasteurella multocida. Examination of 16 antibiotics against these pathogens revealed that the incidence of antibiotic-resistant microoganisms were very high and that many of these isolates had multiple resistance to various commercially available antibiotics such as penicillin, ampicillin, erythromycin, streptomycin, norfloxacin, and tetracycline. These results suggest that the use of antibiotics in a farm should be controlled in order to decrease the number of antibiotic-resistant microorganisms were very high and that many of these isolates had multiple resistance to various commercially available antibiotics such as penicillin, ampicillin, erythromycin, streptomycin, norfloxacin, and tetracycline. These results suggest that the use of antibiotics in a farm should be controlled in order to decrease the number of antibiotic-resistant microorganisms.
