A patient (Painter+Viszula mixed breed, 4 months old, male), with chief historic sign of acute vomiting, hemorrhagic diarrhea, anorexia and dyspnea during 4 days was admitted ta College of Veterinary Medicine, Kyungpook National University. Necropsy findings were revealed ulcer and hemorrhage contained hemorrhagic diarrhea in gastrointestinal tract, severe emphysema and hemorrhage in the lung and kidney and cardiac hypertropy. Histopathological changes showed emphysema, hyperemia and hemorrhage in the lung, severe hyperemia, hemorrhage, hepatic vacuolation and cellular necrosis in the liver, hyperemia, hemorrhage, necrosis of tubular epithelium in the kidney, hemorrhage in cardiac muscle and hyperemia, necrosis and sloughing of epithelium in the intestine. In this case, we diagnosed as a paraquat poisoning.

Congenital chloride diarrhea (CLD) is a rare inherited autosomal recessive disorder. Mutations of the solute carrier family 26 member 3 gene cause profuse, chloride ion rich diarrhea, which results in hypochloremia, hyponatremia and metabolic alkalosis with dehydration. If a fetal ultrasound shows bowel dilatation suggestive of bowel obstruction, or if a neonate shows persistent diarrhea and metabolic alkalosis, CLD should be considered in the differential diagnosis. The severity of CLD varies, but early detection and early therapy can prevent complications including growth failure. We report a case of dizygotic twins affected by CLD who had been born to non-consanguineous parents. Both of them showed growth failure, but one of the twins experienced worse clinical course. He showed developmental delay, along with dehydration and severe electrolyte imbalance. He was diagnosed with CLD first at 6-month age, and then the other one was also diagnosed with CLD.

Bovine coronavirus (BCoV) is associated with severe diarrhea, dehydration, and depression, which result in significant economic damages in the dairy and beef cattle industries worldwide. However, differences in the gut microbiota structure and their correlations with differing physiological parameters between BCoV-infected calves with diarrhea and recovered calves are not well understood. In this study, fecal specimens were collected from 10 post-weaned calves, before and after 2 months of fluid therapy, and the samples were used for microbiota analysis. Following recovery, the alpha-diversity profiles (observed operational taxonomic units [OTUs], and Chao1, Shannon, and Simpson indices) changed significantly when compared with those of calves with diarrhea. Beta-diversity analysis exhibited significant differences in gut microbiota compositions between calves with diarrhea and those in the recovered state. The abundances of eight phyla and thirteen genera in feces changed markedly after restoration of BCoV diarrhea. In addition, our correlation study clearly revealed that increased abundances of the genera Caproiciproducens, Pseudoflavonifractor, and Oscillibacter negatively correlated with serum glucose, and phosphorus levels, but positively correlated with serum chloride in calves with diarrhea, whereas increased abundances of the genera Peptostreptococcaceae;Clostridium (Clostridium cluster XI), Intestinibacter, Cellulosilyticum, Ruminococcus, Romboutsia, Paeniclostridium, Clostridiaceae;Clostridium and Turicibacter in recovered calves showed the opposite pattern. These results suggest that structural changes of the gut microbiota after recovery from BCoV infection correlate with changes in physiological parameters. In conclusion, our data provide evidence of gut microbiota-composition changes and their correlations with the physical profiles of post-weaned calves, before and after fluid therapy for BCoV-related diarrhea.

Porcine epidemic diarrhea (PED), transmissible gastroenteritis (TGE) are an acute viral enteritis. colibacillosis by E coli is a microbial enteritic disease in suckling piglets[1]. These infectious intestinal diarrheal diseases cause severe diarrhea to suckling piglets, so that lead to enormous economical loss in swine-product industries. Ig-Top (AD Biotech, Korea) is a immunomodulator with IgY the specific yolk-antibody for PED, TGE and E. coli and oligosaccharide. The purpose of this study was to investigate protective effects against PED virus, TGE virus E.coli and in suckling piglets by oral administration of the Ig-Top. (omitted)

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.

Nowadays, Klebsiella oxytoca is described as a causative organism for antibiotic-associated hemorrhagic colitis (AAHC). Here we report two cases of pediatric AAHC, from which K. oxytoca was cultured after starting amoxicillin-clavulanate or amoxicillin treatment. The patients developed severe abdominal pain and a large amount of bloody diarrhea. K. oxytoca was obtained in intestinal fluid culture of a boy through the colonoscopy. On the other hand, colonic tissue culture and intestinal fluid culture were negative of the other patient. K. oxytoca was detected in stool culture when he was admitted. These cases showed characteristic endoscopic findings of segmental hemorrhagic colitis, and both boys recovered spontaneously within 2-3 days after they stopped taking the antibiotics. Therefore, in children who develop relatively large amount of bloody diarrhea after antibiotic treatment, we should consider AAHC caused by K. oxytoca.

Bovine viral diarrhea viruses (BVDVs) were isolated from cattle with respiratory and diarrhea signs as well as persistently infected cattle. These isolates were analysed serologically to characterize serogroups and to compare serological relationship with reference viruses of type I and II. Most isolates from calf diarrheal cases and persistently infected individuals showed a significant difference in cross-neutralization test with the viruses isolated from nasal discharges showing severe respiratory signs. Serologically most of the commercial vaccine strains could be classified into classical BVDV (type I) such as NADL strain. This serological difference among BVDV isolates suggested the need for new vaccines to protect cattle from both respiratory and enteric BVDV infections in field. The immunogenicity of BVDVs which showed a good propagation capability in MDBK cells and high rates of neutralizing activity (isolate : KD26-1, PHG, B5 and 95002) against all viruses used in this study, was confirmed in guinea pig when treated as single or combined groups.

Phylogenetic and nucleotide analysis revealed that severe acute bovine viral diarrhea virus (BVDV) outbreaks from Korean indigenous calves belonged to BVDV-2a, and were identical to those of the highly pathogenic BVDV-2 strain 890, with identical virulence markers and classified as highly virulent. These outbreaks affected young calves (20 and 40 day-old) and were characterized by hemorrhagic diarrhea, depression, anorexia, and weakness. The identification of the highly virulent BVDV-2 isolates among Korean indigenous calves may have important implications for epidemiological studies, diagnostic and immunization strategies.
