Myocardial abscess usually occurs as a complication of infective endocarditis or overwhelming septicemia. Coronary artery occlusion caused by myocardial abscess has been rarely reported. A 61-year-old man presented with fever and chill that developed 6 weeks prior to admission. He had a history of cardiopulmonary resuscitation for ventricular fibrillation and cardiac arrest 4 weeks prior to admission. Echocardiography showed a 3xfcm sized mass in the area of the right atrioventricular groove and coronary angiography showed complete occlusion of the proximal right coronary artery. Under the diagnosis of myocardial infarction complicating myocardial abscess, debridement of abscess and coronary artery bypass grafting with right internal mammary artery to distal right coronary artery was performed. Culture from the abscess cavity demonstrated Salmonella arizona.

Vibrio vulnificus is an organism capable of causing septicemia and wound infection in compromised patients. The source of infection is known to be raw oysters and others. The prevalence of the organism in Korean sea water and shellfish is not known. The authors surveyed shellfish and other specimens obtained mainly from a market in Seoul and from ones in Inchon. Five cultures of V. vulnificus were isolated from oyster and clam samples. Two isolates had typical characteristics of the strains isolated from patients, i.e., definite hemolysis and typical biochemical reactions. However, other 2 isolates were sucrose positive, although the identity were confirmed by Center for Disease Control. We do not know wether such strains are pathogenic or not. For the isolation of V. vulnificus from environmental samples, TCBS agar and VV agar were not very selective or differential. We isolated our strains with the use of OF-lactose agar and SPS agar. However OF-lactose agar did not support good growth of V. vulnificus, while SPS agar did not suppress other vibrios.

Improvements in various health indices have been ushered in, along with soaring economic growth in the last few decades in Korea. Life span of Koreans at present stands at somewhere around age of seventies. It seems of worth to elucidate some facets of health profile of historic Koreans during Yi dynasty encompassing about five hundreds years between the 14th and 19th century. Datas on health of historic Koreans are meager with exception for sovereigns for whom royal archives have been preserved intact through centuries. Though the health environments for monarchs are, no doubt, incomparable to that of the grassroot levels during the same period, health profile of monarchs would facilitate to assess health indices for historic Koreans during Yi dynasty. Arithmetic average of life span of 25 consecutive Kings(omitted the last two Kings under Japanese control) is 44.6 years of age 81 year old for King Yongjo and 16 year old for King Danjong, representing two extremes. The principal causes of death are septicemia, subsequent to infections of soft tissue and ether organs(8 in number, one-thirds of all). Secondly, both epidemic disease and vascular accidents caused deaths of three Kings each. Two kings succumbed to diabets and one suicide. The causes for the remainder, eight kings are hardly ciarified. The monarchs who contributed in establishment of new Yi dynasty with highspirited and disciplined survied beyond their fifties and sixties. In contrast, those who reigned during mid - era of the dynasty at its culmination succumbed to death in their young adulthood, most likely due to their indulgence in court life.

Haemophilus somnus, Mycoplasma bovis and Pasteurella multocida were responsible for respiratory diseases in bovine. Methods for identifying these bacteria had poor sensitivity and specificity. In this paper, PCR assays were applied for rapid identification of H. somnus, M. bovis, P. multocida B:2 and P. multocida capsular types. The specific PCR products were amplified from H. somnus, but not from other bacteria. Ten-fold diluted H. somnus were mixed with P. multocida and then the mixed cultures were inoculated on agar plates. After incubation, PCR was performed with harvest from agar plates and could detect as few as 3.4 CFU/ml of H. somnus. The primers MboF and MboR produced an amplification product unique to M. bovis and sensitivity of PCR was as low as 100 pg of DNA. Only serotype B:2 of P. multocida, the causal agent of haemorrhagic septicemia in bovine, was specifically amplified in PCR among the 16 reference serotypes. The multiplex capsular PCR typing for P. multocida was produced the P. multocida specific product as well as the capsular serogroup-specific product. The present PCR assays should be useful for the rapid identification of bacterial pathogens from bovine respiratory diseases.

The distribution of hemolytic Vibrio sp. from sea water of three main beaches located in Busan (Gwangan(G), Haeundae(H) and Songjeong(S) beaches) was investigated from June to September 2006 ; this is mid-summer and the main season for bathing. The monthly detection ratio from each beach was 29.2% (7 of 24 samples, G), 33.3% (8 of 24 samples, H), and 16.7% (4 of 24 samples, S). The most probable number(MPN) of strains detected ranged from 1.8-36(G), 1.8-180(H) and 1.8-18(S) MPN/100mL. Of the isolated strains, 24 strains showed definite hemolytic activity. These 24 strains were identified as Vibrio fluvialis, Vibrio vulnificus, Aeromonas hydrophila, Actinobacillus ureae and Eikenella corrodens. Vibrio fluvialis was detected from all three beaches investigated. Vibrio vulnificus was detected from Haeundae and Gwangan beaches. Gwangan beach had a higher detection ratio of Vibrio sp. than Haeundae and Songjeong beaches. These results suggest that seafood harvested from the vicinity of theses beaches may cause food poisoning and risk management to prevent Vibrio septicemia is required, especially for Haeundae and Gwangan beaches.

Neonatal infection caused by Cronobacter species can result in serious illnesses such as bacteremia, septicemia, meningitis, and death in at-risk infants who are orally fed contaminated reconstituted powdered infant formulas. The objective of this study was to compare the virulence among three Cronobacter species strains by using an animal model for human neonatal Cronobacter species infections. We acquired timed-pregnant ICR mice and all owed them to give birth naturally. On postnatal day 3, each pup was administered orally a total dose of $1{\times}10^7$ CFU Cronobacter species strain 3439, CDC 1123-79, and 3231. Mice were observed twice daily for morbidity and mortality. At postnatal day 10, the remaining pups were euthanized, and brain, liver, and cecum were excised and analyzed for the presence of Cronobacter species. Cronobacter species were isolated from cecum and other tissues in inoculated mice. In the tissues of Cronobacter species infected mice, meningitis and gliosis were detected in the brain. In this study, we identified the virulence among Cronobacter species strains by using a neonatal mice model which was a very effective animal model for human neonatal Cronobacter species infections.

Annular pancreas is a rare congenital anomaly with the descending duodenum encircled by a ring of pancreatic tissue, which may cause partial or complete obstruction of the duodenum. In newborn, the symptoms can be those of duodenal stasis resulting from partial intestinal obstruction secondary to some degree of duodenal stenosis. A male newborn weighing 2.0 Kg was born by C-section delivery at 37 weeks' gestation to a 27-year-old mother who had a hydramnios. He was in relatively good condition at birth except regurgitation of saliva and intermittent apnea. A plain film of the abdomen showed the double-bubble of gas filled stomach and proximal duodenum, and upper gastrointestinal series showed a dilated proximal duodenum, with a complete obstruction of the descending duodenum. Intraoperative finding revealed encirclement of the duodenal second portion by pancreatic tissue. Duodenojejunostomy was performed. After the operation, he had developed two serious complications, neonatal septicemia by Enterobacter cloacae on postoperative day 12 and systemic candidiasis on postoperative day 19, and been managed with ventilatory support, antibiotics, and antifungal agents with recovery.

The most common and the most serious complication of the burn is infection, which is to a certain extent inevitable in the light of present knowledge and experience. From the burn wound as a rule there may be cultured at any given time the prevailing flora of the individual patient and of the hospital attendants and ward environ ment. Even without contamination from outside sources, organisms embedded in hair follicles and sweat glands survive the sterilizing effects of heat and serve as potential sources of localized and systemic infection. With necrotic tissue serving as nutrient material for pathogens there may occur, in succession, cellulitis, extending necrosis, lymphangitis and final septicemia. This is to report a case of osteomyelitis due to facial burn of 32 year old Korean male. The authors treated the patient by curettage and thin split thickness skin graft. The post operative course was uncomplicated and result was excellent.

Aeromonas hydrophila is a pathogen to fish as well as human. It is a food-borne disease, and causes severe mortality in fish, and sometimes severe septicemia in human. In this study, a rapid detection method using latex agglutination has been developed for A. hydrophila. Polyclonal antibodies were raised against membrane and whole cells of three isolates from rainbow trout. Among these, latex particles coated with antibodies raised against whole cells of isolate No. 2 showed the best sensitivity. With latex particles coated with this antibody, we could detect $5{\times}10^4$ CFU of A. hydrophila in 5 min. The cross-reactivity with bacteria constituting the normal intestinal microflora and other pathogens for rainbow trout was insignificant. This latex agglutination assay method produced positive reaction with all clinical isolates of A. hydrophila which were identified by species-specific PCR for 16S rRNA in A. hydrophila.

A retrospective study of 17 dogs with hyperadrenocorticism (HAC) was performed to evaluate the clinical and clinicopathological outcomes in dogs with pituitary-dependent HAC or adrenal gland-dependent HAC. Sixteen dogs were monitored at day 10, 30 and 90 then every 3 month after first presentation. In each examination, physical examination and ACTH stimulation test and client questionnaire were performed. In 17 cases, eight dogs were successfully treated with mitotane therapy (median dose 16.7 mg/kg; range 5.3 to 50 mg/kg, SID); another one dog showed favorable response, but the clients declined to further treatment before the full control of the disease had been achieved; four dogs showed poor response to treatment. One dog was euthanized due to septicemia. These results showed canine HAC can be medically managed successfully without side effects at the doses used in this study.
