The slaughter process for cattle will inevitably transfer some bacteria onto the carcasses. The goal of food safety programs is to minimize and effectively remove this contamination. This study was attempted by the Verif
machine-vision technology that might be useful for reducing microbial indicator counts and could reduce the contamination chance of E coli O157:H7 and Salmonella spp on beef carcasses. For the evaluation of the effectiveness of the Verif
technology, 80 samples were examined by the inspection device over 15 days. On an examination of FDS-positive samples compared to negative controls from the same carcasses, aerobic plate counts were bigger than the negative control samples (5.26 vs 4.60 log). Enterobacteriaceae counts were greater on the positive samples than the corresponding negative control samples (2.07 vs 1.17log). There was a consistent correlation between samples detected by the Verif
system with detectable counts. For example, 100% of positive samples had detectable APC and 91.2% of positive samples had detectable TCC. Therefore, if areas detected as positive for contamination by the Verif
system were removed from the carcasses, significant sources of microbial contamination will be reduced for objective compliance with HACCP. This results suggest that the use of Verif
machine-vision technology might be useful for reducing microbial indicator counts (APC, TCC) and could help reduce the risk of presence of E coJi O157:H7 and Salmonella spp on Beef carcasses.

A total of 501 serum samples were selected from blood samples that were submitted to Department of Veterinary Pathology, Kangwon National University from all provinces in Korea from September 2001 to August 2002. Their sera were examined for antibodies to swine influenza virus subtype H1N1 (SlV H1N1) and porcine repro-ductive and respiratory syndrome virus (PRRSV) according to the age of pig, season, and herd size using enzyme-linked immunosorbent assay. The seroprevalence of SIV H1N1, PRRSV, and dual infection were 39.12%, 61.48%, and 25.95%, respectively. The seroprevalence of SIV H1N1 according to herd size was not significant differences (p>0.05). The results showed that the PRRSV infection spread widely in swine herds throughout the country.

A protein chip based on surface plasmon resonance (SPR) imaging was developed for measuring classical swine fever virus (CSFV) antibody using a recombinant gp55 protein as an antigen. The diagnostic potential of SPR imaging for detecting antibodies to the CSFV gp55 protein was compared with that of a enzyme -linked immunosorbent assay (ELISA) using 70 pig sera. There was a strong positive correlation between the SPR imaging and ELISA (n=70, r=0.916, p<0.01). Therefore, the SPR imaging, which is a label-free and high-through put method, is expected to be a valuable tool in the serodiagnosis of CSFV.

In order to evaluation of prevalence of rotavirus and/or coronavirus, forty suckling Korean indigenous calves (between 2 and 98 days old) with acute diarrhea were investigated by the immunochromatographic rapid test in the field (veterinary practice) on October and on December 2006. Rotavirus and coronavirus were detected in 13 (32.5%) and 8 (20.0%) of the fecal samples from diarrheal calves, respectively. The highest mortality rate in diarrheal calves occurred in the neonatal period from 2 to 7 days old. Totally, 40.0% of diarrheal calves showing acute enteritis were not detected with rotavirus and/or coronavirus. The rotavirus infection rate was significantly difference (p<0.05) between October and December, and the detection rate of rotavirus was bigger than that of coronavirus. These results suggested that rotavirus can be frequently associated with acute diarrhea of suckling calves and affected with changes of temperature.

The effects of intraduodenal administration of Clostridium perfringens type D whole culture in goats were evaluated to develop a reliable experimental model of enterotoxemia in this species and the eventual evaluation of treatment with different drug preparations was also carried out. A total of 28 conventionally reared healthy unvaccinated black bangle goat kids of 6-12 months of age were dosed intraduodenally with whole cultures of C peliringens type D. Four kids were used as controls and received sterile, nontoxic culture medium intraduodenally. All animals received starch solution into the abomasum. The clinical signs developed within 12 hours of post inoculation that were similar to those observed in naturally occurring cases. Among the clinical signs, diarrhea was most common (96.43%) followed by dyspnea (53.57%) and central nervous system (CNS) signs (25.0%). The most striking postmortem findings consisted of necrotizing pseudomembranous colitis (100.0%), lung edema (69.23%) and fluid filled intestines (61.53%). The protocol thus provided a reasonable model of naturally occurring enterotoxemia in goats, producing a range of clinical signs and postmortem changes similar to those observed in the natural disease. Beside this, treatment trial with different drug preparations showed penicillin combined with antitoxin was most effective (100.0%), followed by combination of oxytetracyclin with antitoxin, and combined preparation of antitoxin and sulfur drugs both showed 75% recovery rate. On the other hand, treatment with antitoxin, penicillin and oxytetracycline singly could protect goat enterotoxaemia only 25.0%, 50.0% and 50.0%, respectively. Thus in the present study, it eas observed that antisera in combination of antibiotics gave better recovery rate than the antitoxin or antibiotics alone.

Tuberculin positive cattle without gross tubercle lesions should be confirmed by the bacteriological examination to determine the state of the infection. To overcome the time-consuming and laborious identification by culture and biochemical tests, polymerase chain reaction (PCR) has been used to identify Mycobacterium bovis. Due to various lipids in the cell wall of Mycobacterium spp, novel methods of DNA extraction from Mycobacterium spp have been developed. In this study, a newly developed guanidium isothiocyanate/silica DNA extraction method was directly applied to specimens from the tuberculin positive cattle. DNAs were directly extracted from the lymph nodes and the major polymorphic tandem repeat (MPTR) and mycobacterial protein of BCG 70 (MPB70) were amplified using PCR. The DNA extraction method using guanidium isothiocyanate/silica was efficient and safe, and the MPTR and MPB70 primers were specific to M bovis. Therefore, MPTR and MPB70 PCRs will be useful for the detection of M bovis in the lymph node from skin-test positive cattle.

The tube agglutination test has been used for bovine brucellosis diagnosis in Korea since middle 1950s. The reported high specificity was its value in eradication program. However, the reading of reaction mostly depends on personal experience, thus here we report a way to improve accuracy and uniformity of reading. The tube agglutination was conducted according to the protocol provided by Korean Ministry of Agriculture and Forestry. The intensity of reaction was measured by spectrophotometer. The relationship between turbidity and percentage clearing was generally in direct proportion and linear. The correspondent percent transmittance at 75, 50, and 25% clearing were 91, 82, and 73, respectively. Then, the degree of percentage of clearing at given international unit was measured. With about 1.5 unit of serum, the maximum percentage clearing was observed. The international unit showing 25, 50, and 75 percentage clearing were 0.61, 0.83 and 1.35, respectively. Based on the information obtained using international standard serum, the calculation of international unit of test serum was available. According to the protocol for bovine brucellosis diagnosis which provided by Korean Ministry of Agriculture and Forestry, the available range of detectable international unit was between 15 and 538. And the corresponding international units for suspicious case ranged between 42 and 127. Of the 35 sera from B abortus infected cattle, about half of them had more than 538 international units. Collectively, the reading of turbidity using spectrophotometer and application to international unit improved accuracy and uniformity of reading.

Bovine brucellosis has occurred for years in Gyeonggi province under the national test and slaughter scheme. The serum agglutination test (SAT) is a diagnostic tool to confirm the disease despite the argument on its specificity. We selected 8 farms where only one or two individuals were diagnosed as brucellosis through SAT at the primary regular herd check and isolated the causative organism and characterized the species by species-specific PCR. The pathogen isolation was successful in 6 farms out of 8 farms by microbiological culture, showing the successful rate of 75%. The isolation rate of the causative organism represents 70% from supra-mammary lymph node and 60% from uterine tissues. They were characterized as Brucella abortus biovar 1 after biotyping by PCR, showing the fragment of 498 bp. Five of 8 farms were diagnosed as brucellosis two to four times more over the intervals of two or three months. Here in this study we briefly showed the correlation of the sporadic outbreak of brucellosis tested by SAT and the isolation of the causative organism. Moreover one or two reactors against brucellosis among considerable size of herd may indicate that SAT failed to detect potentially infected individuals in the incubation stage or chronic phase of the disease.

A study on the relation between some husbandry practices and brucellosis in goats in Bangladesh was conducted at selected areas of Mymensingh and Dhaka district, Bangladesh, from March 2005 to May 2006. Sera from 300 goats were tested by Rose bengal test (RBT), plate agglutination test (PAT), tube agglutination test (TAT) and mercaptoethanol test (MET). Out of the 300 goats, 1.670% (n=5) were positive to RBT and PAT respectively, and 2.0% (n=6) were positive to TAT and 2.33% (n=7) were positive to MET. The prevalence of brucellosis was bigger in goats reared collectively (n=2, 4%) than reared individually (n=5, 2%), and bigger in goats housed with concrete floor (n=2, 4%) than that of bare floor (n=5, 2%). The rate of brucellosis was higher in goats keep separately (n=6, 2.61%) than that of kept with other animals (n=1, 1.43%) especially with cattle. Out of 290 goats from free grazing, 7 were positive but no positive reactor(n=10) was found in non grazing goats. In conclusion, however, seroprevalence of brucellosis had no statistically significant association with rearing type, housing type and grazing or not.

The aim of this study was to examine the epidemiological features of Eimeria in calves with acute diarrhea. Samples were collected from between 15 days and 90 days old calves (n=83) in Gimje area from March 2006 to March 2007. Feces of bloody diarrhea were examined for the presence of Eimeria oocysts using a sucrose flotation method. Out of 83 calves, 62 (74.6%) had Eimeria oocysts. In the results of monthly analysis, the highest prevalence (12.0%) of Eimeria oocysts was found on June. In the seasonal infection rate, spring was the highest prevalence (30.1%), followed by summer (24.0%). Furthermore, the highest prevalence (44.5%) was found in calves from between 31 - 60 days old in the analysis by ages. However, there was no significant differences between female and male sex even though the prevalence was slightly bigger in female than in male. The prevalence of the present study to detect Eimria oocysts for infection may have been affected by weather-conditions in the spring. Young calves should be separated to minimize the infection from cattle as much as possible. Additional studies are necessary to find other factors for infection and combining molecular methods with a highly sensitive system for Eimeria detection could be a reliable and economic way of Eimeria eradication.

Neospora caninum (N caninum) is an intracellular protozoa parasite, and its infection is one of the important diseases because it can cause abortion in cattle. This study was conduct to gain epidemiological data for more effective control of the disease. Bloods were collected from 2,162 cattle on 90 farms from February to September 2006. Serums were tested for antibodies to N caninum using ELISA CherdCheck, IDEXX). The dairy breed presented a higher proportion of seropositive results than that of Hanwoo. The estimated proportion of N caninum-positive dairy farms was 71.1 %, but the overall seroprevalence was estimated as 22.8%. The seroprevalence of dairy cattle and Hanwoo were 31.0% and 4.9%, respectively. There was no significant difference in the seroprevalence by age, but the not-intensive managed farms had a high seroprevalence (OR=1.91, p-value<0.01). The antibody rate of cattle with dog(s) was greater than that of those without dogs (OR=2.13, p-value<0.01). There was a significant difference in abortion rate between seropositive cattle and seronegative ones (OR=6.2, p-value<0.01).

Fungus generally doesn't produce toxic or harmful substances so it has low chances to cause food poisoning. However it leads to change appearance, odor and characteristics of the contaminated foods and result in sanitary risk problems. Therefore the contamination of fungi should be prevented since they are not proper for human consumption. Green fungi with white outline raised from the air cell of cooked eggs which were collected by Gyeongi Livestock Veterinary Service in August, 2006. The results came out after the cultivation using Sabouraud's Dextrose Agar(SDA). The conidium appeared white and monospore, the shape of colony was round and oval. Conidiophore was brown and granulated and wrinkles and formed. It was confirmed as Aspergillus nidulans based on the dying using Lactophenol cotton blue, the observation of septum and vesicle from the grown spores, and rDNA sequencing.

Uremia was diagnosed in a slaughtered 20-month old bull. It had no special clinical signs, but many lesions associated with uremia were observed at postmortem inspection. It had a lot of ascites. Kidney, urinary bladder and ureter were enlarged, congested and hemorrhagic, and the incised section of those slightly smelled nasty. However, the precise cause of uremia in this case could not be completely identified.
