Fowl cholera is an infectious disease caused by .Pasteurella multocida, affecting domesticated and wild birds. It usually appears as a septicemia of sudden onset with high morbidity and mortality, but chronic conditions that characterized by localized infections often occur. 13wks broiler breeders were submitted to the Kyung-pook national university for diagnosis. Clinical signs included approximately 1% mortality, severe lameness, ruffled feathers and swollen and/or cloudy eyes. At necropsy, the outstanding lesions were seen swollen hock joint, which were suppurative or caseous exudates, inflammation of conjunctiva, severe pneumonia and epicarditis. The causative agent was isolated from the hock joint, liver, sinus and sternum of the chickens, and performed physiological and biochemical test. To identify the serotype of P. multocida, capsular serotyping was conducted by multiplex polymerase chain reaction (PCR). In the antimicrobial susceptibility test, the isolates were resistance to the aminoglycosides. In this study, we confirmed chronic fowl cholera (FC) caused by P. multocida in broiler breeders in Korea.

Pulmonary paragonimiasis is the infectious disease of lung, due to 'Paragonimus westermani'. The clinical manifestations are various, and the main symptoms are chronic cough and persistent hemoptysis. Radiological findings mainly include thin walled cyst, migrating patch pulmonary infiltration, transient linear shadow, and hydropneumothorax, etc. The differential diagnosis should include pulmonary tuberculosis, pneumonia, other parasitic diseases, and rarely lung malignancy if the mass-like lesion is present. Recently, the incidence of paragonimiasis is very low. But the physicians should suspect paragonimus infection, if the patient has chronic respiratory symptom such as hemoptysis and lives in the endemic area such as Korea. A case of pulmonary paragonimiasis confirmed by histological basis of lung was presented with a review of the literature.

Cytomegalovirus (CMV) is currently the most common agent of congenital infection and the leading infectious cause of brain damage and hearing loss in children. Symptomatic congenital CMV infections usually result from maternal primary infection during early pregnancy. One half of symptomatic infants have cytomegalic inclusion disease (CID), which is characterized by involvement of multiple organs, in particular, the reticuloendothelial and central nervous system (CNS). Moreover, such involvement may or may not include ocular and auditory damage. Approximately 90% of infants with congenital infection are asymptomatic at birth. Preterm infants with perinatal CMV infection can have symptomatic diseases such as pneumonia, hepatitis, and thrombocytopenia. Microcephaly and abnormal neuroradiologic imaging are associated with a poor prognosis. Hearing loss may occur in both symptomatic and asymptomatic infants with congenital infection and may progress through childhood. Congenital infection is defined by the isolation of CMV from infants within the first 3 weeks of life. Ganciclovir therapy can be considered for infants with symptomatic congenital CMV infection involving the CNS. Pregnant women of seronegative state should be counseled on the importance of good hand washing and other control measures to prevent CMV infection. Heat treatment of infected breast milk at $72{^{\circ}C}$ for 5 seconds can eliminate CMV completely.

Streptococcal pneumoniae is the second most coomon cause of meningitis in infancy and a major respiratory pathogen. It is the one of the most common cause of acquired pneumonia and otitis media in childhood. Intracranial extesion of acute otitis media occur somewhat more often from poorly pneumatized than from well-pneumatized temporal bones and in ears with a history of previous attacks of otitis media. We experienced a case of pneumococcal meningitis with 3 time recurrences in a 6 year-old male patient who had hospitalized with high fever, headache, vomiting and stupor mental state. He was diagnosed as CSF study and brain CT. Brain CT showed poorly pneumatized right mastoid region of temporal bone at that time. We report a case of pneumococcal meningitis with 3 time recurrences due to poorly pnematized mastoid region of temporal bone. A review of literatures was also presented briefly.

장티푸스는 10-15%에서 수막염, 폐렴, 심근염, 간염, 골수염, 파종성 혈관내 응고병증등의 심각한 합병증을 유발할수 있다. 소아에서 장티푸스 병발 후 신장에 발생되는 합병증은 국내외 모두 매우 드물다. 우리는 장티푸스 병발후 단백뇨, 고혈압, 신기능 저하가 동반된 급성 사구체 신염 케이스를 경험후 보고하는 바이다. 이 케이스는 대변 배양검사에서 병원체를 확인할 수는 없었지만 상승하는 Widal 수치로 장티푸스를 진단할 수 있었다. 장티푸스는 유병률은 감소하였지만 고열이 있는 경우 여전히 고려해보아야 하는 중요한 질환이다.

Mycoplasma pneumoniae infection is usually confined to the respiratory tract but it can cause a variety of extrapulmonary manifestations such as rashes, myalgia, hemolytic anemia, cerebral infarction, transverse myelitis, cerebellar ataxia, Guillain-Barre syndrome and meningoencephalitis. Neurologic complications of Mycoplasma pneumonia have been rarely reported until now. Cerebral infarction as a complication of mycoplasma infection in children has been very rarely reported. In our case, in a young girl with M. pneumoniae infection, a cerebral infarct resulted in persistent and significant neurological dysfunction. We report a 11-year-old girl with cerebral infarction associated with clinical and serologic evidence of Mycoplasma infection.

Streptococcus pneumoniae, pneumococcus, is the most common cause of community-acquired pneumonia (CAP). CAP is an important infectious disease with high morbidity and mortality, and it is still one of the leading causes of death worldwide. Many genetic factors of the host and various environmental factors surrounding it have been studied as important determinants of the pathophysiology and outcomes of pneumococcal infections. Various cytokines, including transforming growth factor $(TGF)-{\beta}1$, are involved in different stages of the progression of pneumococcal infection. $TGF-{\beta}1$ is a cytokine that regulates a wide range of cellular and physiological functions, including immune and inflammatory responses. This cytokine has long been known as an anti-inflammatory cytokine that is critical to preventing the progression of an acute infection to a chronic condition. On the other hand, recent studies have unveiled the diverse roles of $TGF-{\beta}1$ on different stages of pneumococcal infections other than mitigating inflammation. This review summarizes the recent findings of the role of $TGF-{\beta}1$ on the pathophysiology of pneumococcal infections, which is fundamental to developing novel therapeutic strategies for such infections in immune-compromised patients.

A review team has been set up in Yong Nahm central Bureau Dong Bang Life Insurance Company to study on yearly treands and Mortalities of life insureds according to the causes of deaths. The subjects included in this study were the Life insureds in these area offices and one Who died within 2 years after the admission during 17 months period between 1984-4-1 and 1985-8-31. In cases of the insurance for educational fund, the subjects were the applicants who pay the dues of insurances instead of the insured youngsters. 1) The most frequent cause of death was malignant newgrowth, the next was heart disease, the third was central nervous vascular system diseases, and the fourth was Hepatitis and Liver cirrhosis. 2) The previous Leading cause of deaths were infectious diseases, Parasitic disease or Respiratory diseases, Such as Pneumonia bronchitis, Tuberculosis, Since remarkable prolongation of the longevity of Korean population in recent years, this has been showed marked changes after 1980, this phenomenon would be in accordance with Bogue's theory. 3) The authors hoped to extend this study to get more clear views, because it covered only a short period and very limitted areas of subjects to make a difinite conclusion on this time.

A 58-year-old man, incapable of maintaining oxygen saturation with mechanical ventilation, was admitted to our hospital for veno-venous extracorporeal membrane oxygenation (ECMO) treatment. He was diagnosed with acute respiratory distress syndrome (ARDS) due to influenza A pneumonia. His condition stabilized with antibiotics and steroid administration, but weaning from ECMO failed due to post-infectious pulmonary sequelae. On day 84 after admission, he underwent bilateral lung transplantation. In the postoperative phase, he did not regain consciousness even after discontinuation of sedatives for 3 days. However, spontaneous pupillary reflex and eye movements were preserved, while communication and upper and lower limb movements were affected. The nerve conduction study was diagnostic of Guillain-Barré syndrome. He was managed with intravenous immunoglobulins and plasmapheresis. Mild recovery of the facial muscles was seen, but he died 24 days post-surgery due to progressive ARDS and sepsis.

Rabbit infectious hemorrhagic fever has been reported in rabbits worldwide. The disease is also frequently reported on Korean rabbit farms, and the pathological study of 9 rabbits on such disease-occurring farms was attempted to identify the pathogen. Clinical signs were torticollis and ear ulceration. Most rabbit died with bloody nasal discharges. At necropsy, multiple hemorrhages and inflammation were observed in heart, lung, liver and uterus. The main histopathologic features were hemorrhagic suppurative meningoencephalitis, fibrinous bronchointerstitial pneumonia, bacteremia, liver cell necrosis, multifocal hemorrhages in kidney and disseminated intravascular coagulopathy. The viral VP60 gene of RHDV was identified by Reverse Transcriptase PCR. Pasteurella multocida organisms were cultured, identified by biochemical test and serotyped as A by multiplex capsular typing PCR. In conclusion, the fatal hemorrhagic disease was due to combined infection with both RHDV and P. multocida in rabbits. To our knowledge, this is the first case report about co-infection with both RHDV and P. multocida in rabbits in Korea.
