Mycoplasma pneumoniae produces illness in man ranging from mild upper respiratory tract infection to severe bronchitis and pneumonia. We experienced a case of mycoplasma pneumonia complicated with acute respiratory failure, cold agglutinin hemolytic anemia, pleural effusion, Raynaud's phenominon and hepatitis in 27-year-old female. She was diagnosed as having mycoplasma pneumonia by detecting mycoplasma antibody and cold agglutinin test and treated effectively with erythromycin.

Purpose: NTM (non tuberculous mycobacteria) is rare cause of surgical site infection after plastic surgery in immunocompetent patients. There are some reports about NTM infection after body contouring procedure from Latin America. But, there is no report in Korea. The purpose of this article is to report 2 patients with soft tissue infection caused by NTM after body contouring procedure. Methods: Two young female patients exhibited signs of inflammation and abscess after body contouring procedure. One patient underwent liposuction. The other underwent HPL (hypotonic pharmacologic lipo-dissolution) injection. Results: The result of tissue cultures were positive for NTM. All patients responded to the combined therapeutic approach. Conclusion: The goal of this article is to raise awareness among plastic surgeons who may encounter such patients in their practice. NTM should be included in the differential diagnosis of surgical site infection after body contouring surgery.

Poultry production in korea is a very complex situation. Large modernized farms and old styles of small farming coexist with one another. This gives rise to a tangled epidemiological situation in terms of infectious diseases. The main poultry diseases of economic importance are colibacillosis, pullorum diseases, Mycoplasma gallisepticum infection, infectious coryza, infectious synovitis, Newcasyle disease, fowl pox, Marek's disease, avian encephalomyelitis, infectious bursal disease, infectious laryngotracheitis, infectious bronchitis and coccidiosis. Avian influenza, fowl cholera and fowl typhoid have not been reported for a few decades, and these are rated as exotic diseases.

병원성 Mycoplasma hyopneumoniae strain 91-3, 비병원성 M. hyopneumoniae 그리고 M. flocculare를 돼지의 기관지섬모상피에 투여시 세포내 $Ca^{2+}$ 농도 [$Ca^{2+]}$$_{i}$ 의 변화를 본 연구에서 조사하였다. M. hyopneumoniae strain 91-3 (300-$\mu\textrm{g}$ml)를 투여시 기관지 섬모상피내의 $Ca^{2+}$가 투여전과 비교시 투여 후 250$\pm$19 nM (net increase)증가하였다 (10회 반복 47 cells). 이와는 대조적으로 비병원성 M. hyopneumoniae (300 $\mu\textrm{g}$ml) (6회 반복 18 cells)와 M. flocculare (300 $\mu\textrm{g}$ml) (8회 반복 24 cells)는 세포내 $Ca^{2+}$의 농도를 증가시키지 못하였다. 위의 결과로 병원성 M. hyopneumoniae 91-3 균주는 비병원성 mycoplasma와는 다르게 돼지의 섬모상피에서 [$Ca^{2+}$]$_{i}$ 을 유도하였으며 이러한 특성은 mycoplasma 감염증 치료에 중요한 단서를 제공할 뿐만 아니라 새로운 치료법의 개발에 유용한 스크리닝 기술에 응용될 것으로 기대된다.

This study was performed to evaluate the effect of commercial swine mycoplasma vaccine (M+$Pac^{(R)}$, Schering-Plough Animal HealthCo.) at different vaccination time points. Total 139 piglets were moved to experimental farm after weaning and were randomly allocated to 3 treatment groups and 1 control group. Piglets of 3 treatment groups (A, B and C) were vaccinated twice at 1 and 3 weeks (A group), 3 and 5 weeks (B), and 6 and 8 weeks (C), respectively. All vaccinates showed higher antibody titers compared with nonvaccinates, and maintained to finish (P<0.001). Performance and RBC/WBC count showed no significant difference between groups. Vaccinates at 6-8 weeks showed better effect on decrease of clinical sign compared with vaccinates at 1-3 weeks and 3-5 weeks and nonvaccinates. Also, lung lesion assessment showed significant difference between vaccinates at 3-5 weeks and 6-8 weeks, and nonvaccinates and vaccinates at 1-3 weeks (P<0.05). Vaccinates at 3-5 score in comparison with other groups. In conclusion, these results suggested that vaccination at 3-5 weeks or later may be more effective than earlier vaccination.

We report the seasonal prevalence of the mycoplasmal pneumoniae of swine (MPS) in slaughter pigs from July of 1999 to June of 2000. Gross finding of lung lesion observed and examined by dot-ELISA. In gross finding of lung lesion from 750 pig samples, 465 (62.0%) was MPS, and 129 (17.2%) was single or double infection with actinobacillosis and pasturellosis. However, 156 (20.8%) had no lesion. In seasonal detection, the prevalence was found to be winter (69.5%), autumn (63.5%), summer (60.0%) and spring (54.7%) in orderly frequency. In dot-ELISA, the result was showed the positive reaction (x16>titre) with 58.0% and negative (x4

Mycoplasma-like organisms (MLO) were identified from three plants. The disease symptoms show stunting, yellowing and witche's broom on Cnidium officinale Makino collected from Ulreung Island, Bupleurum falcatum L. collected from Jangsu, and Plantago asiatica L. collected from Daegwanreung. The particles of MLO were observed in the phloem tissues by a Hitachi Hu-11E electron microscope. C. officinale infected with MLO was frequently observed in Ulreung Island.

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, gastrointestinal track, and respiratory system. On histopathological examination it was found that the nodular lesions were consisted of granoulomatous inflammation accompanying characteristic hyphae ($4{\sim}24{\mu}$ wide) of the fungi.

Today swine respiratory disease is one of the most important diseases because of its economic losses and severe infection nationwide, and swine society as well as veterinary service are trying to prevent the diseases in Korea. This study would like to obtain some information useful for the control of the diseases. A total of 174 lung specimens with lesion consisted of 3 sorts; 60 were collected from nursey pigs requested for diagnostic service from March of 2006 to October of 2007, 58 finishing pigs and 56 sows were selected from slaughterhouse from September to November 2007. In the detection test of pathogens by PCR, porcine circovirus 2 (PCV2), porcine reproductive and respiratory syndrome virus (PRRSV) and Mycoplasma hyopneumoniae were positive in 95.4%, 31.6%, and 20.1%, respectively. Double infection rate with PCV2 and PRRS was 30.4%, PCV2 and M hyopneumoniae was 19.5%, triple infection with PCV2, PRRS and M hyopneumoniae was 5.7%, respectively.

Objectives: The objective of the present study was to identify mycobacterial infection in retired dusty workers who were ineligible for medical care benefits for work-related pneumoconiosis. Methods: Sputum samples were collected from 170 retired dusty workers living in Gangwon-do. The mycobacterial culture was grown in 2% Ogawa medium and Mycobacteria Growth Indicator Tube(MGIT). Mycobacterial species were identified using MolecuTech REBA Myco-ID^Ⓡ. Results: Thirty-one(18.2%) out of 170 sputum samples were identified as positive for culture. Among the positive culture samples, eleven(6.5%) were identified as mycobacterial species. The proportion of mycobacteria was M. avium 2.3%(4/170), M. fortuitum complex 1.2%(2/170), M. intracellulare 1.2%(2/170), M. abscessus 0.6%(1/170), M. tuberculosis(MTB) complex 0.6%(1/170), and MYC(NTM except 19 species) 0.6%(1/170). Conclusions: In comparison with previous studies, the incidence rate of tuberculosis(TB) in retired dusty workers who were ineligible for medical care benefits for work-related pneumoconiosis was higher than in close contact with TB patients, workers exposed to silica, and patients with silicosis. And the proportion of non-tuberculosis mycobacteria(NTM) was higher than that of MTB.
