A 2-year old female African hedgehog (Atelerix albiventris) weighing 645 grams was presented with a well circumscribed mass in the subcutaneous of the left shoulder. It measured $2{\times}2cm$ in size and had a hard texture. There were no clinical signs. In a fine-needle aspiration (FNA) cytological evaluation, mast cells were identified with Wright-Giemsa stain. Mast cell tumor was confirmed and characterized by surgical sampling and histopathological evaluation. Four stains (hematoxylin-eosin, toluidine blue, periodic acid-Schiff, and Safranin O) were examined in order to find an applicable stain for a mast cell tumor histopathological evaluation in hedgehog. This case showed that periodic acid-Schiff and toluidine blue staining were the most useful for assessment of a mast cell tumor in a hedgehog.

The cytological and ultrastructural findings of Pneumocystis carinii(PC) obtained from rats by bronchoalveolar lavage (BAL) are described. All developmental forms of the PC organisms were obtained in the lavage fluid. Papanicolaou stain revealed conglomeration of PC as a foamy cast. The cystic walls of PC were well identified on Gomori's methenamine silver stain. Trophozoites and intracystic bodies were stained by Giemsa and Diff-Quik techniques. Some PC organisms were seen within the alveolar macrophages. Ultrastructurally, the cysts were almost circular in shape, and were nearly devoid of surface tubular extensions. The wall of the cyst was composed of an unit membrane, an intermediate electron lucent layer and an external electron dense layer The cysts frequently contained intracystic bodies, so called sporozoites. Occasionally empty or collapsed cysts with no intracystic bodies, and precysts were found. Trophozoites were variable in size and shape with abundant tubular extensions along the single electron dense pellicle. BAL is a useful method for concentrating the various morphologic forms of PC organisms, and is a rapid diagnostic method for PC pneumonia.

The rate of 67 neonatal calves's infection of Theileria sergenti was investigated in random samples on the farms located in Kyeongki, Chonbuk and Jeju districts of Korea. The criteria used in verifying infection with T sergenti included the detection of parasites by giemsa's stain and acridine orange stain in the blood smear slides. Further evidence of current or previous exposure to T sergenti was based on the demonstration of T sergenti-specific antibody and antigen by the western immunoblot and the indirect immunofluorescence antibody test in the peripheral blood of the calves. The prevalence rates were 35%, 50% and 100% in Kyeongki, Chonbuk and Jeju provinces respectively and the overall prevalence in all the farms was 43.2% by means of acridine orange stain. The parasites that were observed in the peripheral blood of calves was shown surely by the western immunoblot to the characteristic 34KD antigen among the proteins of T sergenti (Korean Isolate). And the antibody of the neonatal calves reacted at the very highest titer(1 : >2,520). These data highlight the significance of T sergenti in the neonatal calf disease in Korea.

For the laboratory diagnosis of Sarcocystis infections especially in domesticated food animals, several antificial digestion techniques were applied for the musculature specimens and several staining techniques was applied for the bradyzoites of Sarcocystis species isolated. The digestion technique using trypsin(0.5%) and sodium chloride(0.85%) mixed solution was regarded as the most valuable for the detection of asexual stages of Sarcocystis in bovine musculature specimens. Optimal time for digestion was approximately one to four hours. The trypsion digestion technique with Giemsa's stain could be helpful for the detection of Sarcocystis prolferative forms and for the observation of the nucleus of the parasite. A systematic detection was also performed in an autopsy for a bovine carcass naturally infected with Sarcocystis species, and the asexual stages such as metrocytes and bradyzoites were observed in the specific organs, respectively.

Babesia gibsoni infection was diagnosed and treated in three hunting dogs which were hospitalized to the Veterinary Teaching Hospital, College of Veterinary Medicine, Seoul National University between April 4 and August 29, 1987. All three dogs revealed severe anemia, hemoglobinuria, splenomegaly and markedly decreased PCV, RBC count and hemoglobin. The anemia was regenerative, as characterized by increased numbers of nucleated erythrocytes, polychromasia, anisocytosis, reticulocytosis. B. gibsoni was identified by examination of blood smear stained with Giemsa stain. The forms of B. gibsoni identified in this report were pleomorphic such as singnet ring, oval, comma, dot and elongated forms. The maximal percentages of erythrocytes infected with one or more B. gibsoni organisms were 39%, 20% and 40%, respectively. The Tick, Haemophysalis longicornis was assumed to be the vector of babesiosis in these cases. Specific treatment consisted of diminazene aceturate and supportive treatment consisted of whole blood transfusion, lactated Ringer's solution, vitamin B complex and broad spectrum antibiotics. All three dogs had convalesced successfully after treatment.

1989년 6월 1일부터 8월 31일까지 안분비물을 주소로 본원 외래를 방문한 신생아 및 입원중인 신생아를 대상으로 Giemsa염색 및 Chlamydiazyme 검사, Gram염색 및 세균 배양검사를 실시하여 다음과 같은 결론을 얻었다. 1. Chlamydia성 결막염으로 진단된 환자는 전체 대상 환아의 34.6%였다. 2. Chlamydia성 결막염 발생시 일령 은 6일에서 15일사이가 가장 많았으며 남녀 성별차이는 없었다. 3. Chlamydia성 결막염으로 진단된 환아는 임상 증상 및 이학적 소견만으로 다른 세균성 결막염과 구분할 수 없었다. 4. 안분비물의 세균배양시 아무균도 자라지 않았던 경우가 61.5%였으며 균주가 자란 경우는 Pseudomonas aeruginosa가 19.2%로 가장 많았으며 Chlamydia성 결막염으로 진단된 경우도 1례에서도 S. aureus가 배양되었다. 5. Chlamydia성 결막염으로 진단된 환아 중 폐렴이 동반된 례는 없었다.

2-deoxy-D-glucose가 첨가된(25 pg/ml) 최소액체 배지에 8.5시간 전 배양하여 swelling 시킨 conidiospore에 2% driselase와 2% ${\beta}-glucuronidase$를 동량 혼합한 효소용액을 처리하여 반응시킨 결과 protoplast형성 시간 2시간이내로 단축 시킬 수 있었다. 5% Ficoll(m.w. 400,000)용액을 사용하여 conidial protoplast를 보다 순수하게 분리 벙제할 수 있었으며, protoplast를 Giemsa로 핵 염색한 결과, 대부분의 protoplast는 하나의 핵을 갖고 있었다. 또한 전자현미경으로 관찰한 결과 conidiospore에서 유래된 protoplast는 세포벽 성분이 남아 있지 아니한 완전한 protoplast인 것으로 판명되었다. 영양요구성 돌연변이주에서 유래된 conidial protoplast의 융합률은 $3.4{\times}10^{-1}$에서 $4.9{\times}10^{-1}$수준으로 이는 mycelial protoplast의 경우보다 5-28배 가량 높은 수준의 것이었다.

Giemsa solution 염색법에 의한 핵다각체병(N)의 다각체는 염색이 되지 않으나 중장형다각예병(C)의 다각체는 잘 염색되어 염색성에 의하여 구별할 수 있었다.

Following the death of more than 250 goats in one herd of 800 goats, imported from Australia, an epidemiological investigation was undertaken to determine the probable aetiology of this apprently mysterious disease. The syndrome was characterized by severe anemia(Hematocrit <20% ; normal range 24 to 48). All the affected animals were imported from Australia and all the motalities occurred during the period from September to November, 1992 Giemsa stain, acridine orange and indirect immunoflourescence tests were utilized in a survey involving 239 goats reared in Chonbuk Province. The positivity rates by acridine orange for anaplasmosis or piroplasmosis were 60.8% and 66.2% for imported and indigenous breeds respectively. It is tenatively concluded that the probable cause of death was anaplasmosis.

This report deals with a 9-year-old neutered male Yorkshire terrier that had been suffered from vomiting, bloody diarrhea, anorexia. On exploratory laparotomy, pale-pink $10{\times}6cm$ duodenal mass was found and submitted to the Department of Veterinary Pathology, College of Veterinary Medicine, Seoul National University. Histologically, the duodenal mass consisted of compact sheet of poorly demarcated, highly infiltrative neoplasm. The neoplastic cells were round to polygonal and contained scant to moderate amounts of granular basophilic cytoplasm and eccentrically located irregularly round nuclei with stippled chromatins. The neoplastic cells were positive to lamda light chain immunohistochemically but were uniformly negative for toluidine blue stain and giemsa stains. Based on these results, this case was diagnosed as primary extramedullary plasma cell tumor of duodenum.
