A 120 kg, 3-year-old, male ostrich (Struthio camelus) was submitted to the veterinary teaching hospital, Chonbuk national university, for chronic weight loss, anorexia, small hard fecal pellets, and lethargy. Illness was first noticed approximately 2 weeks before submission. Although the bird was able to stand, he was extremely weak and cachectic. Blood examination indicated that the bird was dehydration (PCV: 55%). Fluoroscopic and lateral abdominal radio-graphic view indicated impaction of distended proventriculus with bigger rocks than normal. Anesthesia was induced with ketamine (10 mg/kg, IV)-xylazine (1 mg/kg, IV) combination and maintained with ketamine (10 mg/kg, IV) at intervals of 8 to 15 minutes during the entire procedure. After induction of general anesthesia, the bird was positioned in dorsal recumbency. The skin was incised approximately 15cm caudal to the caudal margin of the sternum and extended 20 to 25 cm caudally. After the proventriculotomy was peformed, the impacted material that weighed 3kg contained rocks in 4 to 6cm diameter was removed. The incision of proventriculus was closed in 2 layers. Cephalothin sodium (30 mg/kg, IV, q12hrs) and dexamethazone (2 mg/kg, IM, q24hrs) was administered before and after 5 days of the operation. The bird was eating well and defecating normal feces after 3 weeks of the surgery

A 1-year-old, female Bengal tiger (Panthera tigris tigris) presented signs of weight loss and dark browncolored diarrhea. On fecal examination, numerous intact and broken red blood cells were found, but both parasites and inflammatory signs were absent. No significant findings were seen in serum biochemistry profiles, including electrolytes, with negative feline pancreatic lipase immunoreactivity (fPLI). Diagnostic kits using feces or peripheral blood were negative for feline parvovirus, feline coronavirus, feline immunodeficiency virus, and feline leukemia virus. Based on the result of feline trypsin-like immunoreactivity (fTLI) concentration ($4.6{\mu}g/L$), the tiger was provisionally diagnosed to have exocrine pancreatic insufficiency (EPI). After this diagnosis, pancreatic enzymes were prescribed. The feces of the tiger returned to normal form and her weight was increasing. EPI is uncommon and not described extensively in Felidae, including domestic cats. Feline EPI is associated with a variety of non-specific signs and it should be considered in the differential diagnosis of cases presenting with weight loss, diarrhea, and other gastrointestinal signs. In this case, the patient was strongly suspected to have EPI based on the very low fTLI concentration, though the concentration of fTLI in tigers has not yet been determined. This is the first report to present a suspected EPI case in Bengal tigers.

Protozoan parasite, the genus Eimeria, causes an intestinal disease, coccidiosis, in young broilers. Coccidiosis induces significant economic loss in poultry production. This study was designed to identify the prevalence of Eimeria spp. in broilers in Gyeonggi province, Korea. Fecal samples from broilers at 94 farms were collected in two chicken slaughterhouses between March and June 2015. Eimeria infection was determined by microscopic examination and PCR using ITS-1 region. The prevalence of Eimeria was 58.5% (55 of 94). E. acervulina was identified in 96.4% of samples, E. tenella in 81.8%, E. maxima in 12.7%, E. praecox in 12.7%, E. brunetti in 5.5%, E. necatrix in 1.8%, and E. mitis in 1.8%. Body weight (BW) of broilers infected with both E. tenella and E. acervulina ($mean=1.53{\pm}0.19^Bkg$) was significantly lower than broilers with E. acervulina positive/E. tenalla negative ($mean=1.74{\pm}0.07^Akg$) or Eimeria negative ($mean=1.65{\pm}0.15^Akg$) (Duncan's multiple range test, P<0.01). High prevalence of Eimeria tenella and the impact on the broiler body weight shows the importance of this protozoa in broiler industry. Development of the periodic monitoring strategy and systemic management for the purpose of the prevention/eradication of Eimeria infection among broilers is required.

Infection cases of diphyllobothriid tapeworms are not much in the below teen-age group. We report a case of Diphyllobothrium nihonkaiense infection in a 13-year-old boy. He presented with severe fatigue, occasional abdominal pain at night time. He also had several episodes of tapeworm segment discharge in his stools. By his past history, he had frequently eaten raw fish including salmon and trout with his families. Numerous eggs of diphyllobothriid tapeworm were detected in the fecal examination. We introduced amidotrizoic acid as a cathartic agent through nasogastroduodenal tube and let nearly whole length (4.75 m) of D. nihonkaiense be excreted through his anus. After a single dose of praziquantel, the child's stool showed no further eggs, and his symptoms disappeared. The evacuated worm was identified as D. nihonkaiense by mitochondrial cox1 gene analysis. Here we report a successful extracorporeal worm extraction from an infection case of D. nihonkaiense by the injection of amidotrizoic acid.

Opisthorchis viverrini (OV) liver flukes are common parasites found in central and southern Laos and constitute a major public health problem in the country. Laos people continue to have the habit of extensively consuming raw or half-cooked fish which are intermediate hosts. This study aimed to determine the prevalence and factors associated with OV infection in the population of Thakek district, Khammouane Province. This cross-sectional analytic study covered 237 subjects who filled out structured questionnaires. Fecal examination for OV infection was performed by Kato's thick smear method. Data analysis was carried out using STATA Version 10.0. Multiple logistic regression was applied. The results showed that the infection rate of OV was 54.8%. Factors associated with OV infections were gender, a habit of defecation in fields and raw fish (goi bplaa dip) consumption. Opisthorchiasis and associated cholangiocarcinoma development thus appear to remain as important concerns in Laos.

A thirty-five week old elk was referred for Chronic Wasting Disease (CWD) confirmation from Chungnam province in Korea. Necropsy revealed much bloody contents in the lumen of small and large intestines, and reddening of its mucosa. Microscopically, few coccidia showing various developmental stages were infiltrated in lamina propria of small intestine with granulomatous inflammation and congestion. They were identified as Eimeria spp. according to their location and morphological characteristics. Because fecal examination and oocyst culture were not available, the species of the Eimeria could not be confirmed. There were no detection of pathogenic bacteria such as clostridia and virus in intestinal contents. CWD was shown to be negative in immunohistochemistry test. In conclusion, it was the first Eimeria case detected in small intestine of Korean domestic elk as far as we know although Eimeria spp. were not the main cause of death.

In the course of surveying the internal parasites of domestic animals, a large number of eggs and mites were detected in the feces and feeds of cattle, pigs, chickens and ducks. Three kinds of mites were identified in the present studies: Acarus siro (Linnaeus), Tyrophagus putrescentiae (Schrank) and Cheyletus malaccensis (Oudemans). The eggs of the mites were similar to those of flukes. In the fecal examination, therefore, it is necessary to differentiate the mite eggs from fluke eggs. The mites found in the present studies live by organic materials. Thus, they were found in the mixed commercial animal feeds. The spoiling of animal feeds by these mites remains to be verified. The damage of the gut epithelium of animals by these adult mites has to be examined more thoroughly, although macroscopic changes were not detected in the present studies. In the commercial animal feeds, the mites were largely found during the warm, humid seasons. As these mites can cause dermatitis in man, care should be taken not to contact continuously with the contaminated feeds.

A 35-year-old female patient was referred to our hospital with neurologic symptoms after continuous epidural block performed 2 days earlier. She die not have any prior no previous lumbar surgery or experience trauma, intraspinal hemorrhage, infections or other known causative factors to associate with neurologic symptoms. Continuous epidural block is widely used for postoperative pain control. Complications can occur with this block including postduralpuncture headache, epidural abscess and rare cases of arachnoiditis etc. We experienced such a case of spinal arachnoiditis after continuous epidural block. Neurologic examination revealed painful bilateral hypoesthesia below $S_2$ level dermatomes, urinary and fecal incontinence and various degrees of leg weakness. The following day, the patient was noted to have bilateral sacral radiculopathies and lesion on proximal portion of both tibial nerve. CSF study reported: protein 264 mg/dl, sugar 64 mg/dl, WBC $7/mm^3$. L-spine MyeloCTscan results were unremarkable. She was discharged after a month of hospitalization and has regular checkups but her neurologic symptoms show no signs of improvement.

Trichnuris suis does not excrete eggs during larval stage as well as in particular adult stage, It is impossible to diagnose by use of fecal examination method in those periods. Therefore, serological diagnostic method can be very useful for those stages. In order to produce monoclonal antibody, specific somatic and secretory-excretory (SE) antigens of T. suis were identified and analyzed by SDS-PAGE and Western blot. Monoclonal antibody-producing hybridoma cells were cloned, which were made of popliteal lymph node of BALB/c mice immunized with a 45 kDa somatic antigen of T. suis. Five clones (1B9, 2C4, n2C5, 2D7 and 2D8) showing strong responses to T. suis antigens were selected and the isotype identified. All monoclonal antibodies were IgG1 isotype and the light chains were k chain. Established monoclonal antibodies reacted specifically to somatic and SE antigens of T. suis and did not cross-reacted to antigens of ascaris suum, trichuris vulpis, or Trichinella spiralis. The sensitivity of somatic and SE antigens against these monoclonal antibodies were significant (p<0.01) associated with those of positive and negative sera.

This study examined complex infections with various enteropathogens and the genetic diversity of bovine norovirus (BNoV) in 932 fecal samples from diarrheic calves in South Korea. Overall, seventeen (1.8%) of the samples tested positive for BNoV following RT-PCR examination. All BNoV-positive samples were co-infected with other intestinal pathogens, including bovine Rotavirus, Giardia, Cryptosporidium, and Escherichia coli. The genetic diversity of the BNoVs shared high nucleotide identity (98.1-99.5%) and amino acid homology (93.5-98.1%) with genotype 2 BNoV (GIII.2) strains. In conclusion, BNoV infections with GIII genotypes were detected in complex infections of diarrheic calves in South Korea.
