Cheong, K.S. (Yongdong Branch of Veterinary Research Inst., (Korea R.)) | Rim, B.M. (Chonbug National Univ., Chonju (Korea R.). Coll. of Veterinary Medicine)
The etiologic agents of mucormycosis are several nonpathogenic fungi of the order Mucorales and are ubiquitous. A total of 82 chickens were infected with the disease and developed anorexia, diarrhea, malnutrition, dyspnea, and paralysis in a chicken farm, Sokcho, Kwangwon. At necropsy there were multiple nodular lesions and hemorrhages in livers, spleens, kidneys, gastro intestinal track, and respiratory system. On histopathological examination it was found that the nodular lesions were consisted of granulomatous inflammation accompanying characteristic hyphae (4-24 micro wide) of the fungi

1989
Kim, D. | Han, H.R. (Seoul National Univ., Suwon (Korea R.). Coll. of Veterinary Medicine)
The effects of the serum total protein and immunoglobulin levels of the colostrum-conferred Korean native calves at 2 days of age on the disease incidence during the suckling period were studied. Serum total protein, total immunoglobulin, IgG, and IgM levels of 6 Korean native calves died from septicemia were lower than those of calves survived (p0.05). Korean native calves having low serum total protein and immunoglobulins were affected with diarrhea earlier in life, when compared with calves having high serum levels (P0.05). Korea native calves having low serum total protein were affected with bronchopneumonia earlier in life, when compared with calves having high serum levels (P0.05). Korean native calves having low serum neutralizing antibody titers to bovine viral diarrhea virus had high incidence rate of BVD, when compared with calves having having high serum neutralizing antibody titers (P0.05)
