Purpose: This study was done to examine incidence of diarrhea and explore factors influencing occurrence of diarrhea in patients admitted to intensive care units (ICU). Methods: For this retrospective research, data based on inclusion criteria were collected from the electronic medical records for 142 patients admitted to a university hospital ICU from September 2014 to August 2015. Statistical analysis was conducted using SPSS/WIN 22.0 program. Results: Incidence of diarrhea was 53.5% during the 12-month study period. Diarrhea occurred at 4.54 days and continued for 1.79 days on average. Average total frequency of diarrhea was 5.56 times. Increased ICU stay, enteral nutrition, and infection state were significant predictors of the occurrence of diarrhea. Infection increased risk of diarrhea 3.4 times and enteral nutrition increased risk of diarrhea to 2.2 times greater than patients not receivng enteral nutrition. Conclusion: Diarrhea in ICU patients is associated with multiple factors that should be considered to implement preventive strategies. Infection control should be emphasized, and close monitoring of diarrhea should be provided for those with enteral nutrition. Further studies are warranted to determine standardized clinical definition of diarrhea and diarrhea risk factors in ICU patients with different levels of severity and comorbidity.

Purpose: The purpose of this study was to investigate the difference in the incidence of diarrhea among the subjects given hypertonic and isotonic nutrients to the nasogastric tube feeding patients in the a critical care setting. Methods: This study is aquasi-experimental study with a pre & post-test design. The sample size of 40 was calculated based on Cohen's formula (1988). The total of 40 subjects who signed the informed consent were randomly selected and divided evenly into two groups, experimental and control group. Results: There are no significant differences between the two groups in homogeneity test (sex, age, albumin level, the use of antibiotics, antacid, and $H_2$ blocker). However, the frequencies of occurrence in diarrhea according to the density of nutrients formulation indicated a statistical difference at the level of .005 (p=.001): diarrhea occurred in four of 20 (20%) of the experiment group, but 14 (70%) of the control group. Also the onset date of diarrhea in the experiment group is later than that of the control group. Conclusion: The research findings suggest that we should begin with low density nutrients for nasogastric tube feeding, and increase its density gradually to decrease diarrhea incidence in the critical care setting.

This study was perfomed to examine the distribution of causative agent of piglets diarrhea in eastern Chonnam province from February 1994 to March 1995. The causative agents of diarrhea were examined by bacterial culture test, parasitological test and serological test against PED, TGE and Rota. The 35 isolated E. coli were tested for antibiotic sensitivity. The results obtained were as follows. 1. The incidence of 81 piglets with diarrhea was most prevalent as 39.5% in the age of 2 to 4 weeks, compare to 34.6% in the age of 5 to 8 weeks and 16.0% under 1 weeks and 9.9 % in the age of 9 to 11 weeks after birth. 2. The incidence of 81 piglets diarrhea showed bacterial diarrhea(75.3%), viral diarrhea (35.8%) and parasitological diarrhea(18.5%). When compared the isolation frequency of each etiological agent, enteropathogenic E. coli was most prevalent as 55.5% in bacterial diarrhea, rotavlrus enteritis as 18.5% in viral diarrhea and trichuriasis as 13.6% in parasitological diarrhea. 3. The complicated infection of piglets was most prevalent as 41.7% in rotavirus enteritis with enteropathogenic E coli in 24 complicated piglets diarrhea. 4. In antibiotic sensitivity test, isolates showed moderatly resistance to Tobramycin, Amikacin, Imipenem, Trimethoprim/Sulfamethoxazole, Gentamicin, Ampicillin but sensitivty to Ticarcillin/K. The 30 E. coli isolate showed multiple drug resistances in 3 different antibiotics.

Diarrhea is reported as one of the most common diseases in calves. It is thought to be a major cause of productivity and economic loss to cattle producers. The aim of this study is to provide a better understanding of well-known diarrheagenic pathogens and incidence of diarrhea in Korean calves. In this study, the relationship of calf diarrhea and pathogens were investigated from calves under 60 days of age in five areas of Korea from April to July, 2016. Of examined fecal samples, 38.3% was positive for any pathogens, and Giardia was the most common pathogen (25.5%). The incidence of diarrhea was 31% from pathogen-negative fecal samples whereas 61.1% from pathogen-positive fecal samples, suggesting high correlation between pathogenic factor and diarrhea. In addition, 80% of E. coli (K99) positive calves showed diarrhea, suggesting E. coli (K99) could be highly pathogenic. The incidence of diarrhea and infection rate increased with age. Rotavirus was revealed as a major pathogen in calves under 20 days of age, and the infection rate of Giardia increased rapidly in calves 20 to 39 days of age. The information on interconnections between clinical diarrhea and pathogens would contribute to developing strategies for treatment of calf diarrhea.

Purpose: The purpose of this study was to investigate incidence and factors related to diarrhea in an intensive care unit (ICU). Methods: Retrospective correlational design was used. Data were collected from reviewing medical records of 210 patients stayed at an ICU in one university hospital, Seoul. Patients were included in the study if they 1) had no gastrointestinal disorders or fecal incontinence before coming to the ICU, 2) stayed longer than 5 days at the ICU, 3) were not on stool softners, 4) were without abdominal surgery, and 5) were 20-year-old or older. Results: The incidence of diarrhea was 27.1%. Durations of ICU stay, antibiotics administration, and enteral feeding were found to be statistically significant factors correlated with diarrhea. The enteral feeding was the significant predictors of the diarrhea in ICU. Conclusion: Since characteristics of diarrhea in ICU patients is shown to be multifactorial, nursing strategies for evaluating and managing related factors are recommended.

This study was conducted to determine the effective environmental control measures in preventing calf diarrheal disease in farms. It was found that the high numbers of calves in a cow house was directly related with the high incidence rate of diarrheal diseases. When the number of calves was increased in a cow house, it was difficult to reduce the diarrheal diseases of calves. It was revealed that the incidence rates of calf diarrheal disease were dramatically reduced when the delivery house which faced south. The periodical changes of bedding materials seemed beneficial good to control the possible resident infectious agents, including pathogenic viruses and bacteria. The control of the delivery time was important for reduction of calf diarrhea. It was revealed that September and October were the best time as the delivery period. In order to use old cow house as a delivery house, it should be sterilized by the disinfectant and the flame. When the diarrheal feces were removed as soon as possible, the transmission of diarrheal diseases among calves In the same house was reduced. When the diarrheal feces were not disposed, the incidence rate of diarrhea reached up to 50%. When the morbid calves were not quarantined, the incidence rate of diarrhea was 100%. In contrast, when the diseased calves were quarantined from other calves, the incidence rate of diarrhea was reduced, remarkably. The mean recovery time from the diarrhea of the treated calves in the southern cow house was much faster than that in the north cow house. The treatment of calves in a clean and well-ventilated cow house with dry bedding was more effective than that in a cold, wet, and dark house. It could be postulated that the most important environmental factor in the reduction of diarrheal diseases of calves is the blocking of the entry of the infectious agents. The complete sanitation and control of the delivery house in the using farm is more important than building a new cow house, for prevention of calf diarrheal diseases.

This study was investigated the effects of feeding the combination with Lactobacillus plantarum and Bacillus subtilis on the diarrhea incidence and fecal microflora of weaned calves. A total of 12 newly weaned calves were allocated to two dietary treatments in a randomized design based on body weight. The dietary treatments included a commercial basal diet supplemented with: 1) no microbial inoculants (Control); 2) a mixture of Lactobacillus plantarum and Bacillus subtilis (LB). Calves were fed diets for a 4-week period. At the end of the experiment, the counts of fecal lactic acid bacteria and Enterobacteriaceae in LB were significantly improved compared to control (P<0.05). Over the 4-week period, fecal scores and duration of diarrhea in LB were significantly decreased compared with those in control (P<0.05). The present results suggest that LB is a potential feed additive which could be used for the balance of intestinal microflora and the prevention of diarrhea in Korean native calves.

An epidemiological study was conducted to investigate five diarrhea-causing pathogens (coronavirus, rotavirus, E. coli, Cryptosporidium, Giardia) using a rapid diagnostic kit in Hanwoo calves with diarrhea in Chungcheongbuk-do, Korea, from 2018 to 2021. A total of 22,417 fecal samples were collected from calves under 1 year of age; of those, 13,518 (60.3%) were positive for five bovine diarrhea antigens. The antigen positivity rates for rotavirus, coronavirus, E. coli, Giardia, and Cryptosporidium were 34.5%, 11.0%, 8.2%, 4.7%, and 2.0%, respectively. The prevalence of the five pathogens in calves was statistically higher in autumn and winter. The highest prevalence of the pathogens was observed in the under 1 month age group, and the incidence of diarrhea decreased with age. Rotavirus was a major pathogen in calves under 1 month of age, whereas the prevalence of E. coli increased with age. This study provides epidemiological evidence of the prevalence of calf diarrheal pathogens in Chungcheongbuk-do, Korea, which will facilitate early diagnosis and development of measures against calf diarrhea.

Reproductive performance of gilts and sows in ordinary piggeries was investigated with special reference to litter size, piglets weaned per litter, the cause of preweaning mortality and the incidence of diarrhea. Biochemical properties of Escherichia coli isolated from piglets with diarrhea were also determined. The results obtained are summarised as follows: 1. Of the 2,226 gilts and sows farrowed, average number of piglets born alived and weaned piglets per litter were 8.9 and 7.1, respectively, indicating that both gilts and sows lost more than 20% of all their piglets prior to weaning. 2. The causes of preweaning mortality in order of prevalence were diarrhea (39.3%), pneumonia (20.0%), crushing (13.8%), starvation (11.0%) and born weak (10.3%). 3. Incidence of 3 diarrheal syndromes of piglets, i.e. 1 week diarrhea, 3 week diarrhea and post-weaning diarrhea were 18.4%, 66.1% and 15.5%, respectively, showing that most farms were suffering from so called 'white scours' in piglets 14~28 days old. 4. Biochemical properties of 268 cultures of E. coli isolated from diarrheal piglets were tested and compared with those of standard strains of porcine origin. All those properties of isolates were matched to standard E. coli teated while variable results were obtained with haemolytic capabilities of cultures tested. 5. Of 147 isolates 16 cultures (10.9%) were identified as colicin producers.

A study investigated the effects of Galla Rhois (GR) on growth performance and diarrhea incidence of postweaning piglets. One hundred 28-day-old piglets were randomly assigned into five experimental groups, which were a basal diet alone (NC), chlortetracycline 0.3 g/kg feed (PC) and supplemented with GR 1.0 g/kg feed (GR 1), GR 2.0 g/kg feed (GR 2), and GR 4.0 g/kg feed (GR 3). After 28 days of administration, final body weight (BW) and feed conversion ratio of PC, GR 2 and GR 3 was significantly different compared to those of NC (p < 0.05). Additionally, the average daily gain (ADG) and average daily feed intake (ADFI) of PC and all groups treated with GR was significantly different compared to those of NC (p < 0.05). Especially, final BW, ADG, ADFI and feed conversion ratio (FCR) of GR 2 and GR 3 were not significant different compared to those of PC. In fecal scores and duration of diarrhea, PC and all groups treated with GR were significantly different compared to NC (p < 0.05). In hematogolical and serum biochemical analysis, there were no significant differences in any of the hematogolical and serum biochemical parameters examined in either NC or all groups treated with GR. The results of this study indicated that GR could be a potential candidate as feed additives for the improvement of growth performance and incidence of diarrhea in piglets.
