  • One fungus was isolated from lesions on imported chinese cabbage leaves in process of quarantine inspection from China. The fungus was identified as Mycosphaerlla brassicicola, based on morphology of perithecia, asci, ascospore, and curtural characteristics. In Korea, this fungus has been quarantine fungus, and not yet report to occur. Perithecia of the fungus were globose, dark brown with apical papilate ostioles. The size was 90-100 ${\times}$ 130-135$\mu\textrm{m}$. Asci were bitunicate, 8-spored and 38-43 ${\times}$ 15-l9$\mu\textrm{m}$. Ascospore were irregularly biseriate, hyaline, cylindrical, 2-celled, and rounded at the ends. Optium growth temperature of the fungus was at 20$^{\circ}C$ on PDA but did rarely grow over 24$^{\circ}C$. Colony on PDA was of black aerial mycelia.

  • Thirteen species of mealybugs were intercepted in quarantine at Korean ports of entry on plant materials from China over the past 9 years (2000-2009). Of these, Phenacoccus madeirensis Green has been newly reported in China through this study. This list and key are provided to assist in identifying intercepted specimens of mealybugs from China.

  • Occurrence of the oak wilt disease (Raffaelea sp.) was confirmed in 2004 for the first time in Korea. By using pictorial keys, morphological characteristics of Platypus koryoensis (Murayama), a vector for this disease in Korea, was compared to Platypus quercivorus (Murayama), a vector of oak wilt in Japan. Additionally, suggestions were made for the future research of the vector of oak wilt disease in the northeastern Asia.

  • Clinically, three holstein dairy cattle showed the inappetence and decrease of milk production with severe lameness and pain. Grossly, strawberry-like proliferation of the skin between the heel bulbs were observed 4${\times}$5${\times}$1.5cm in size. Histopathologically, severe hyperplasia of epidermis, parakeratotic hyperkeratosis and multifocal ulceration of cornified cell layer, acanthosis, spongiosis of prickle cell layer and irregular arrangement of basal cell layer were seen. And focally observed the lesions of necrotic vasculitis, infiltration of inflammatory cells, congestion and hemorrhage. Spirochete bacteria were found in necrotic and outer proliferated epidermal cells by Levaditi's silver stain. Clinical and pathological findings were consistent with dermatitis verrucosa.

  • A species-specific 760 base pair(bp) BamHI to EcoRI DNA fragment(fMG-2) of lipoprotein gene was isolated from a Mycoplasma gallisepticum(M gallisepticum) genomic library. Based on the DNA sequence data of fMG-2, a pair of 25bp primers was synthesized. When used in the polymerase chain reaction(PCR), 732bp DNA products were amplified from 6 standard strains and 10 field isolates of M gallisepticum, but not from 2 Mycoplasma synoviae and 7 other Mycoplasma species. The lower detection limit was 100fg of the genomic DNA. Identity of the PCR products was confirmed by comparison of patterns of restriction endonuclease analysis with AseI, DraI, EcoRV and SspI.

  • Trichinellosis is a parasitic zoonosis of public health importance. It is caused by Trichinella spiralis which has a wide host range including humans. In the present communication, the ELISA technique was employed on a total of 803 blood samples from 7 selected pig breeding farms in 1996 for diagnosis and surveillance of trichinellosis. Out of the entire 803 samples, nine were found to be suspected while one was positive by ELISA. But western blot analyses employed for further confirmation have shown that all of 10 samples did not react to larval excretory-secretory product antigens. These results indicate that pig breeding farms included in the present study are free from trichinellosis . However, it does not mean Korea is free from trichinellosis since human trichinellosis has recently been reported. The necessity of continued surveillance for trichinellosis in both pigs and wild animals was discussed.

  • This study is concerning on the Space Modification and Facilities Characteristics of the Busan Exported-cow Quarantine Service Station(1909) before and afrter on the limits of 1945. For on this purpose, National Archives & Records Service(DJB0002115), field survey, documents records and modern aged map were analysised by each period phases, 1909, 1924, 1946, 1951 and now so on. At results on this study is the discovery on the meaning of this placeness, Space Modification and Facilities Characteristics till now before the 120 years ago. And this place has been comprehenive meaning unique dwelling form and almost rarely existing refuge village of Korea War in Korea.

  • Blindness was observed in five calves born from cattle fed only a commercial feed of growing stage and dried rice straws for about two years in a farm in Gyeongsangbuk-do province. Three of them died within a month after birth, and a body and sera of his mother and other 19 cattle were submitted for diagnosis. At necropsy, the calf was very weak and filled with cerebrospinal fluid in the cerebrum. Any histopathological lesion including atrophy of death of optic nerve cells was not observed, but the irregular proliferation such as lace pattern of choroidal cells and lymphocytic infiltration just below choroid was observed. No pathogen was detected as a result of the etiological tests on the internal organs of calves and bloods. In addition, the levels of serum vitamin A in different affected and his mother cattle were all lower than normal. Finally, we determined this case as an encephalopathy caused by maternal vitamin A deficiency in a calf. This report is an extreme example of how important it is to supply adequate s diets and a good quality of hay for each stage of growth in cattle.

  • Six to seven-month-old 10 beef calves in 140-head beef cattle farm in Gimpo-si, Gyeonggi-do were suffered from ataxia and astasia. Two of them were submitted to Animal and Plant Quarantine Agency for diagnosis in July 9, 2015. At necropsy, the radius and tibia of both calves showed irregular thickening and hemorrhage of the physis in addition to hemorrhage and disruption of trabeculae in metaphysis. Histopathologically the physis showed irregular tongues of cartilage remaining the metaphysis. Disorganization, hemorrhage and fibrosis were observed in metaphyseal and epiphyseal bones. The serum 25-hydroxyvitamin $D_3$ ($D_3$) and calcium levels were lower than normal range. In addition, the serum $D_3$ levels in the other 9 calves of the same farm were lower than normal levels. Based on the pathological examination and serum chemistry measurements, we diagnosed this case as rickets caused by vitamin D deficiency in calves.
