Bovine viral diarrhea virus (BVDV) is very important disease in domestic and wild ruminants and has a world wide distribution. Cattle persistently infected with BVDV (BVDV-PI) are the primary reservoir for BVDV infection in Korean native cattle herds. The prevalence of cattle persistently infected with BVDV (BVD-PI) was determined using 4,260 heads from 29 Korean native cattle farms at 8 districts from 2011 to 2012. The sera and ear nothches were collected for each sample. We surveyed BVD-PI cattle using antibody ELISA and antigen capture ELISA for detection of antibody and antigen respectively. Three thousand seventy-six cattle (72.2%) were positive for BVDV antibody and a total of 27 BVD-PI cattle were found in 12 farms. 11 cattle (40.7%) out of the total 27 BVDV-PI cattle were six months old or under. The positive rate of BVDV antibody (83.2%) from 12 farms with BVD-PI cattle was higher than the positive rate of BVDV antibody (63.6%) from 17 farms without BVD-PI cattle.

Escherichia coli (E. coli) and Salmonella enterica (SE) infections in pigs are major source associated with enteric disease such as post weaning diarrhea. The aim of this study was to investigate the effects of Pediococcus pentosaceus in weaned piglets challenged with pathogen bacteria. In Experiment.1 90 weaned piglets with initial body weights of 8.53 ± 0.34 kg were assigned to 15 treatments for 2 weeks. The experiments were conducted two trials in a 2 × 5 factorial arrangement of treatments consisting of two levels of challenge (challenge and non-challenge) with E. coli and SE, respectively and five levels of probiotics (Control, Lactobacillus plantarum [LA], Pediococcus pentosaceus SMFM2016-WK1 [38W], Pediococcus acidilactici K [PK], Lactobacillus reuteri PF30 [PF30]). In Experiment.2 a total of 30 weaned pigs (initial body weight of 9.84 ± 0.85 kg) were used in 4 weeks experiment. Pigs were allocated to 5 groups in a randomized complete way with 2 pens per group and 3 pigs per pen. Supplementation of LA and 38W improved (p < 0.05) growth performance, intestinal pathogen bacteria count, fecal noxious odor and diarrhea incidence. In conclusion, supplementation of 38W strains isolated from white kimchi can act as probiotics by inhibiting E. coli and SE.

Purpose: The gastrointestinal system is the most commonly affected organ, followed by the lungs, in patients with primary immunodeficiency disease (PID). Hence, it is common for children with PIDs to present with gastrointestinal symptoms. We aimed to analyze the clinical and histopathological findings of patients who were initially admitted to pediatric gastroenterology/hepatology clinics and subsequently diagnosed with PIDs to identify the clinical clues for PIDs. Methods: The demographic, laboratory, and histopathological findings, treatment modality, and outcomes of patients initially admitted to the pediatric gastroenterology/hepatology unit and subsequently diagnosed with PIDs were recorded. Results: The study included 24 patients (58.3% male; median age [range]: 29 [0.5-204] months). Common clinical presentations included chronic diarrhea (n=8), colitis (n=6), acute hepatitis (n=4), and acute liver failure (n=2). The association of autoimmune diseases, development of malignant diseases, and severe progression of viral diseases was observed in 20.8%, 8.3%, and 16.6% of the patients, respectively. Antibody deficiency was predominantly diagnosed in 29.2% of patients, combined immunodeficiency in 20.8%, immune dysregulation in 12.5%, defects in intrinsic and innate immunity in 4.2%, autoinflammatory disorders in 8.3%, and congenital defects of phagocytes in 4.2%. Five patients remained unclassified (20.8%). Conclusion: Patients with PIDs may initially experience gastrointestinal or liver problems. It is recommended that the association of autoimmune or malignant diseases or severe progression of viral diseases provide pediatric gastroenterologists some suspicion of PIDs. After screening using basic laboratory tests, genetic analysis is mandatory for a definitive diagnosis.

In the past, antibiotics and antimicrobial substances have been used for the purpose of promoting the growth of livestock or treating livestock, but various problems such as the presence of livestock products or resistant bacteria have emerged. Recently, regulations on the use of antibiotics have been strengthened worldwide, and probiotics are attracting attention as an alternative. Probiotic microorganisms have already been used for human use, such as intestinal abnormal fermentation, diarrhea, and indigestion. In livestock, beneficial microorganisms are increasing in use for the purpose of improving productivity, such as promoting livestock development and preventing diarrhea. Therefore, it is advisable to understand livestock probiotics in deeper and think about effective uses. The role of probiotics in the livestock sector is made with microorganisms themselves, so it is a substance that promotes livestock growth and improves feed efficiency by settling in the intestines of livestock, suppressing the growth of other harmful microorganisms, helping digestion and absorption of ingested feed, and helping to synthesize other nutrients. There is a need for a probiotic that suppresses intestinal bacteria by supplying probiotics used as a means to minimize the effects of stress in livestock management, thereby suppressing disease outbreaks by maintaining beneficial microorganisms and suppressing pathogenic microorganisms. The purpose of this paper is to develop a brand of feed additive probiotics to improve health conditions due to increased feed intake, improve the efficiency of use of feed nutrients, inhibit the decomposition and production of toxic substances, increase immunity, reduce odor in livestock, and improve the environment. We investigated and analyzed feed additive probiotics already on the market, and developed the naming and logo of suitable feed additive probiotic brands in livestock. We hoped that the newly developed product will be used in the field and help solve problems in the livestock field.

Chronic abdominal pain, defined as long-lasting intermittent or constant abdominal pain, is a common pediatric problem encountered by primary care physicians and medical subspecialists. Chronic abdominal pain in children is usually functional, i.e., without objective evidence of an underlying organic disorder. Functional abdominal pain is categorized as functional dyspepsia, irritable bowel syndrome, functional abdominal pain, abdominal migraine, and aerophagia according to the Rome II criteria for pediatric functional gastrointestinal disorders. There is insufficient evidence to state that the nature of abdominal pain or the presence of associated symptoms can discriminate between functional and organic disorders. The presence of alarming symptoms or signs, such as weight loss, gastrointestinal bleeding, persistent fever, and chronic severe diarrhea, is associated with a higher prevalence of organic disease. Most children with chronic abdominal pain are unlikely to require diagnostic testing; such children often need pharmacologic and behavioral therapy.

This is a case report about Dizziness patient classified into 'Yeolhoon(熱暈)' with 'Hyunghwangtang(荊黃湯)' prescription. Donguibogam(東醫寶鑑) says that taking a 'Hyunghwangtang' until one diarrhea, cures ‘Yeolhoon’ with flame and heat attacks a body, get thirsty. 'Hyunghwangtang' resulted from ‘Jangjahwabang(張子和方)’ is prescription that is based on ‘If disease is on the upper half of the body, treatment is done on the lower half of the body.’ We think that study and clinical examination about yeolhoon is considered, in the future.

As the cholera was spread over the Joseon dynasty at 1821, Hwang Doyeon investigated the symptoms like diarrhea, vomiting, muscle cramp and so on, and he presented the cause of cholera as the damage of Primordial-gi caused by abnormal climate and Damp-heat made by taking inadequate foods. He regarded as of great importance the ordinary health condition by guessing the prognosis of the disease, and proposed how to make a diagnosis of dehydration by observing nails and toenails. To treat cholera, he presented the methods of Sipseon-bloodletting and Singwol-moxacautery, and mentioned compound herb remedies and single herbs like garlic etc. He wrote down Mulberry leaves and Argyi wormwood leaves as the preventor of cholera to emphasize the importance of prevention, and mentioned food contraindication in addition to keep from getting worse.

Rotavirus infection is the leading cause of severe diarrhea disease in infants and young children worldwide. Rotavirus infects every child at least once by her/his $5^{th}$ birthday. It has been known that single episode of rotavirus infection can protect or alleviate subsequent illness caused by both homotypic and heterotypic rotaviruses. There are two currently licensed rotavirus vaccines. One is human-bovine rotavirus reassortant pentavalent vaccine ($RotaTeq^{TM}$), which contains five reassortant rotavirus (expressing protein G1, G2, G3, G4 and P[8]) and was licensed in Korea for use among infants in 2007. Another is live-attenuated human rotavirus vaccine ($Rotarix^{TM}$) derived from 89-12 strain which represents the most common of the human rotavirus VP7(G1) and VP4(P[8]) antigens. $Rotarix^{TM}$ was licensed in Korea in 2008. Both live oral rotavirus vaccines are efficacious in preventing severe rotavirus gastroenteritis.

Riemerella anatipestifer (RA) infection is a contagious disease of domestic ducks, turkey, and various other birds. In a flock of mallard ducklings, about 30% of the birds, 3 weeks old, showed lethergy, greenish diarrhea, tremor of head and neck, and died 2-3 days after signs appeared. Grossly, fibrinous exudates covered the heart and surface of the live. Microscopically, mononuclear cells and heterophils were primarily inflammatory cells in the exudate. These were also observed in the meninges in brain. Microbiologically, gram (-) short rod bipolar shaped bacteria were recovered on blood agar and agglutinated by antisera of R anatipestifer. Sulfamethoxasole/trimethoprim were administered and clinically effective. This case was a R anatipestifer infection caused fibrinous pericarditis, hepatitis and meningitis in mallards.
