Serological survey of the rabies virus in dogs reared in the area around the Pukhansan National Park
Korean Journal of Veterinary Service, volume 24, issue 2, 2001, Pages 109~116
This study was conducted to investigate the prevalence rate for rabies antibody (PRRA) of dogs near the Pukhansan National Park and in some other districts in Seoul Metropolitan city. From April to July 2000, a total of 414 serum samples were taken from dogs for breeding (92), pet dogs (162), and unclaimed/stray dogs (162). Rabies virus antibodies were detected by neutralizing peroxidase-linked assay (NPLA). Of 414 sera tested, 145 (35%) were positive to rabies virus antibody. PRRA in Pukhansan National Park area and in the other districts of Seoul city were 34.8% and 35.4%, respectively. There was no significant difference in the prevalence rate between these two districts. PRRA in pet dogs, unclaimed/stray dogs, and dogs for breeding were 39.5%, 35%, and 27.2% respectively. PRRA in dogs from residential areas, apartments, animal hospitals, and farms were 32.5%, 60%, 35.3%, and 26.7% respectively. Especially, the dogs reared in apartments had a significantly higher seroprevalence (60%) than those in residential or farm areas. PRRA in less than 1 year, 1~<2 years, 2~<3 years, and over 3 years old dogs were 14.7%, 40.4%, 38.4%, and 53% respectively, and overall 35% in the dog population. In addition, we found that dogs less than 1 year of age had lower antibody prevalence than those over 1 year of age. It was concluded that enhancement of vaccination is important in the prevention of the rabies, and that rabies vaccines should not be less supplied than the population of the dog.
A study on establishment of bio-hazard analysis and critical control point for pork slaughter house
Korean Journal of Veterinary Service, volume 24, issue 2, 2001, Pages 117~126
To ensure the safety of domestic livestock products, the government made it obligatory to enforce the hazard analysis critical control point(HACCP) in all domestic slaughterhouses. Under the HACCP, most of the hazards generated in slaughterhouses are bio-hazards, especially pathogenic bacteria. In order to reduce to the pathogenic bacteria, critical control point (CCP) is established and controled in the process of slaughter. A study was carried out to measure the level of bacterial contamination of swine carcass in 6 slaughterhouses selected. As a result, the aerobic plate counts(cfu/
) of all samples was
-10 in average, except slaughterhouse C. The level of the aerobic plate counts on the surface of lower loin in slaughterhouse C was
and it was considered that slaughterhouse C should set the process of manual transport of carcass as the CCP. Escherichia coli level was the highest in middle line cut surface. Especially, E coli level of slaughterhouses C and D were about 6.5- and 3.0-fold higher than that of other 4 slaughterhouses. Thus, it was considered that the slaughterhouses C and D should set the process of the entrails treatment as the CCP. The air contamination was measured at two point in a slaughterhouse. The air contamination level was 4-13 times higher than that of the standard Japanese slaughterhouses.
Porcine circovirus: detection of antibodies and virus antigen in Chungbdk area
Korean Journal of Veterinary Service, volume 24, issue 2, 2001, Pages 127~132
Porcine circoviruses(PCV) are the smallest nonenveloped DNA viruses containing a unique single-stranded circular genome. No recognized link was found between PCV infection of pig and disease. But the PCV consistently identified from postweaning multisystemic wasting syndrome(PMWS) and researches indicate that there are strong relationships between PCV and PMWS. Clinical signs were emaciation, dyspnea, high fever with normal appetite. Necropsy findings showed respiratory disease complex lesion and lymph node anomalities. An indirect-immunofluorescent antibody procedure was used to assay swine sera for the presence of PCV atibodies. Antibodies against PCV were found in an average of 20% of the samples tested. The PCV DNA was amplified from lymph nodes collected from pigs. PCV specific primers were successfully amplified PCV DNAs. Further studies are needed to determine the possible role this virus might have in disease.
Prevalence of Cryptosporidium sp among calves and pigs in Jeonbuk province
Korean Journal of Veterinary Service, volume 24, issue 2, 2001, Pages 133~138
Cryposporidium species have a wide host range. These coccidian parasites are found in close association with epithelial cells of many species of animals including mm. The gastrointestinal tract is most commonly affected in young ruminants and this parasite is thought to be considerable importance in calf diarrhea complex. Major outbreaks of cryptosporidiosis have been reported in calves, lambs, pigs and others including avian species. Cryptosporidiosis is transmitted by oocysts of Cryptosporidium species. Because cryptosporidiosis is common infection among animals, early literature considered it a zoonosis. Human infections contracted from calves, cats, and horse feces. However, the resrvoir host is longer considered the major source of infection. Mild cases of disease have been reported in farm workers. Immunosuppressed, very young and very old persons should avoid contact with this parasite because it may cause severe diarrhea. In order to detect of Crytosporidium sp infection from feces of cattle and pigs at Chonbuk Iksan and Kunsan area, sedimentation and modified acid fast stain were applied. The positive rate of Cryptosporidium sp infection from 1, 176 of cattle and 267 of pigs were 0.5 % and 16.8%, respectively. According to area in Iksan and Kunsan, the positive rates were 0.4% and 0.9% from cattle, and 18.9% and 12.1% from pigs, respectively. In cattle, positive detection rate was 0.6% in milking cows but not in Korean cattle.
Abattoir survey of kidney lesions in Korean cattle
Korean Journal of Veterinary Service, volume 24, issue 2, 2001, Pages 139~146
To examine the prevalence and types of kidney lesions in Korean cattle, a survey was carried out at a abattoir in september 2000 and January 2001. The collected kidneys were examined grossly and histopathologically and investigated for the patterns of renal diseases with considering season and sex. Of 735 cattle (99 bulls and 246 cows in September and 140 bulls, 3 steers, and 247 cows in January) surveyed, 301 (41%) cattle had various renal lesions. The most common prominent finding was focal or multiple interstitial nephritis (36.2%). Other lesions included focal or multiple renal cyst (9.1%), infarction (0.1%), hemorrhage (0.3%), and renal atrophy (0.3%). Microscopically, main pathological lesions were acute or chronic interstitial nephritis with moderate infiltration of neutrophil or lymphocyte, respectively. Finally, the kidney lesions are more or less correlated with the meat quality, especially in female Korean cattle.
Studies on the immunization against field strain after live Newcastle disease virus vaccination
Korean Journal of Veterinary Service, volume 24, issue 2, 2001, Pages 147~159
This Study was conducted to determine vaccination programs for the control of Newcastle Disease(ND) in chickens and investigate protective effect against Newcastle disease virus (NDV) after live ND vaccination. Maternal HI antibody titer level of chickens according to day(age) 1, 7, 14, 21, 28 and 35 were decreased gradually as 7.10
1.23 and 0.50
0.71. As a result of HI test and ELISA, both chickens vaccinated with VG/GA strain live vaccine at 1-day-old and chickens not vaccinated do not have antibody titer for protection against NDV at 14-day-old. Except for LaSota strain vaccine, in case of vaccination with VG/GA spray and VG/GA, B1 and LaSota strain drinking water at 14-day-old, the protective effect was 100% in chickens inoculated NDV(
, eye drop) at 21-day-old, but not 10～50% at 28-day-old. These data suggest that live NDV vaccination should be given at 10-day-old 20-25day-old for protect against NDV at periodic outbreaks of ND caused by velogenic viscerotropic NDV in the environment of a farm.
