During The last 11 years from Jan. 1980 to Dec. 1990, 72 cases of salmonellosis has been admitted to the Department of Pediatrics of National Medical Center and evaluated clinical difference between typhoid fever and salmonella gastroenteritis. The results were as follows: 1) The annual incidence of salmonella gastroenteritis insalmonellosis was increased in the latter half of the eighties. 2) Both salmonellosis had its peak incidence in the summer. 3) Salmonella gastroenteritis was highest in the age of less than 5 year in contrast with the age of 6~9 year in typhoid fever. 4) The specimens isolated salmonellae were blood and stool in most cases, especially blood in typhoid fever and stool in gastroenteritis. 5) S.typhi was 16 cases, salmonella group A was 3 cases, group B was 16 cases and Group D and E were a case in each in isolated salmonellae. 6) On the antibiotic sensitivity test, S.typhi was sensitive to the most antibiotics. but the salmonella group B was relatively resisitant to Ampicillin, Carbenicillin, Tetracycline and Chloramphenicol.

One hundred and thirty-two cases(132 eyes) of corneal ulcer were analysed on the clinical and etiologic basis. The history of evident ocular trauma was found in 28.8% of the cases and ocular disease was found in 7.6% of the cases. Positive results were 16/55 in smear and 33/61 in culture, and the most common isolate was coagulase negative staphylococcus in bacteriologic studies. In fungal studies, positive results were 1/42 in smear and 5/42 in culture, and Aspergillus was the most common isolate. Cephalexin was the most sensitive antibiotics for Gram positive organism and carbenicillin and gentamicin were the most sensitive antibiotics for Gram negative orgamsm. These results indicate that gentamicin and cephalexin in combination would be recommended as the initial treatment of wide-spectrum antibiotics coverage for bacterial corneal ulcer until the final culture results and senitivity are available.

In clinical practice, we have occasionally experienced the difficulty to identify the pathologic changes of the non or faint-visualized kidney induced by ureteral stone on I.V.P. and especially to decide whether upper urinary tract infection of ipsilateral side was in accordance with lower urinary tract infection or not. We have checked routinely the bacteriological study of the urine collected from the ureterolithotomized site on operation during last two years. Following results were obtained: 1) Among the cultured urine of 42 patients, organism detected in 20 patients and no growth in remainder. Colifrom bacilli 11(26.2%) Staphylococci 5(11.9%) Streptococci 1(2.4%) Pseudomonas 1(2.4%) TB bacilli 2(4.7%) 2) Sensitive drug pattern of 18 patients, Coliform bacilli (11): Kanamycin, Streptomycin, Chloramphenicol Staphylococcus (5): Penicillin, Kanamycin Streptococcus (1): Penicillin Pseudomonas (1): Geopen From above results, some advantages has been provided in the post-operative management of upper urinary tract infection after removal of the ureteral stone.

Vibrio alginolyticus is a microorganism of marine environment that occasionally occurs as a human pathogen. We isolated V. alginolyticus from a patient with otitis media. A 37-year-old man had been exposed to seawater one month before admission. The isolate showed typical biochemical and characteristics of this organism such as positive Voges-Proskauer reaction, fermentation of sucrose, growth on 10% sodium chloride media. In vitro susceptibility test shows the isolate was resistant to ampicillin and carbenicillin, but was susceptible to other antimicrobial agents. The patient improved with ciprofloxacin and ofloxacin therapy.

Clinical and bacteriological studies were carried out on 74 cases of infants and children with Shigellosis who were cared from May 1972 to Sept. 1977 in our hospital. 1) The age distribution revealed the range between 6 months and 5 ysers (85% of all) with the sex ratio of 42(57%) of male and 32(43%) of female, 13:1,0. 2) The peak incidence was noted in summer, although there were occurrence throughout the year, even in winter. 3) On bacteriological studies, Shigella flexneri was isolated most frequently (73%) and shigella sonnei was the next(32%). Since 1977, however, the rate of isolation was reversed as the former 32% and the latter 62%. 4) Up to 1976, ampicillin was the most effective (in 93%) and carbenicillin the next (in 87%) on sensitivity test. But gentamicin became hightly sensitive in 88%, kanamycin in 81% and ampicillin in 13% since 1977. 70% to 95% of isolated Shigellae were resistant to Terramycin, Chloromycetin, streptomycin and Colimycin. 5) The average duration from the onset to the clinical improvement including stool character was that of 3.4 days. 6) The mortality rate was 2.7% (2 of 74 patients) and they all were under 2 years of age.

A) Bacteriological study and sensitivity test against antimicrobial agents were made on 126 cases of infantile and childhood shigellosis treated at pediatric epartment of St. Vincent hospital from April, 78 to September, 80. The results are follows: 1. Sh. flexneri was most frequently isolated(86.5%) and the next was Sh. sonnei(13.5%). 2. The percentage of resistant strains against antimicrobial agents. Ampicillin: 95.2% Carbenicillin : 90.5% Cephalothin: 78.6% Choloramphenicol: 95.2% Gentamicin: 20.6% Kanamycin: 23.8% Lincomycin: 100% Methicillin: 100% B) The effect of rifampin on bacteriological cure and clinical course in group B shigellosis of sixty-four hospitalized children from one year to five years old age were compared with other antibiotics. gentamicin, ampicillin and trimethoprim-sulfamethoxazole. Based on our study, rifampin was most effective drug in curing of clinical symptoms of shigellosis and eradicating the organisms from stool, and gentamicin was similar effect. Trimethoprim-sulfamethoxazole twas less effective than rifampin and gentamicin, but more effective than ampicillin which has no appreciable effect on the course of shigellosis.

Morganella morganii, a gram, negative rod is often regarded as an opportunistic, secondary invader rather than a primary pathogen on the skin. It has been isolated from blood, sputa, and pus from patients with respiratory tract and wound infections or with bacteremia. A 2-year-old boy presented with erythematous ulcerative lesions on the cheeks and left knee which had a tendency to superficial scarring. The organism isolated from the ulcer displayed a biochemical char acteristics typical of Morganella morganii. The lesions responded well to systemic antibiotic therapy with amikacin and carbenicillin, which were recognized as effective drugs in in vitro sensitivity testing.

OBJECTIVES: Aeromonas species is a gram-negative, facultative anaerobe of the family Vibrionaceae. The organism has been recognized as a pathogen associated with illness in human, such as acute gastroenteritis, cellulitis, septicemia, and other rare diseases. METHODS: To evaluate the clinical significance of Aeromonas bacteremia in Korea and it's susceptibility of antibiotics, we evaluated the 17patients with Aeromonas bacteremia. Identification was done by use of API 20E system and antibiotic susceptibility was tested with disk diffusion method. RESULTS: Male to female ratio was 11:6, and mean age was 54.1years(8-85years) old. Liver cirrhosis was the most common underlying disease(10cases of 17patients, 58.8%a). Other underlying diseases were as follows: gallstone in 2cases, cholangiocarcinoma in 2cases, and aplastic anemia in 1case, cerebral infarction in 1case. But one had no underlying disease. So Aeromonas bacteremia were occurred in 14immunocompromised patients(82.3%), and in 10patients with hepatobiliary diseases, A. hydrophila was most commonly isolated(13cases, 764%), and the A sobria(4cases, 23.5%) was infrequently isolated. The overall fatality was 47%, and there had no significant difference in fatality between A. hydrophila and A sobria All Aeromonas species had resistance to ampicillin and carbenicillin. CONCLUSION: Because Aeromonas bacteremia may occur through water-borne route, especially in immunocompromised host. We should pay attention to immunocompromised patients, espacially having hepatobiliary disease.

We have treated 4-year-old with amikacin and rifampin, who suffered from bacterial meningitis due to gentamicin-resistant Pseudomonas aeruginosa. There was no complication during treatment. Even though we didint check audiometry and BUN and/or creatinine, urinalysis was normal and physical examination revealed no abnormalities. He had been treated fora about 3 months with various antibiotics including gentamicin, intravascular and intrathecal, and carbenicillin. Fever, headache and meningeal irritation signs recurred intermittently in spite of continuous treatment. The culture of the CSF showed P. aeruginosa, which initially was sensitive to gentamicin but became resistant to it. The computed tomography of the brain showed diffuse ventricular dilatation with no abnormal shadow in the cerebral hemisphere and posterior fossa. So we decided to administer rifampin 300mg P.O. daily and amikacin 120mg I.M. daily. Faver became normalized after 14 days of treatment. Neurologic examination was normal. The culture of CSF at that time revealed no growth of P. areugicnosa. He was discharged after 40 days of treatment. As mentioned above, no problem due to amilacin alone or amikacin with refampin. Until now, relationship between amikacin and refampin was not clear. Amikacin alone may be efficient to gentamicin-resistant P. aeruginosa infection. But because amikacin was given through intramuscular route in stead of intrathecal route and daily dosage of amikacin was 8mg/kg in stead of 15mg/kg, which was permissible dosage, the role of rifampin might not be neglected as trivial, even though there was no proof that rifampin was effective against Pseudomonase areuginosa espercially which was gentamicin-resistrant.

BACKGROUND: The number of reported cases of contact lens related ulcerative keratitis has markedly increased. Pseudomonas aeruginosa is one of the most virulent pathogen in contact lens wearers with corneal ulcer. It causes a rapidly spreading ulcer with copious mucopurulent discharge and occasionally corneal perforation. We analyzed the clinical and microbiological findings of 20 cases of culture-proven pseudomonas keratitis in contact lens wearers with a brief review of literature. METHODS: Twenty cases of Pseudomonas keratitis in contact lens wearers were reviewed retrospectively. All patients were seen at the department of ophthalmology, Konyang Hospital during the period from April 1994 to September 1997. RESULTS: The male to female ratio was 9 to 11. The age distribution ranged from 16 to 64 years: 10 patients in their 20s, 7 in their 30s, and each in their 10s, 50s, and 60s, respectively. The duration of lens wear before developing keratitis was variable from 5 weeks to 12 years. Seven cases(35%) of them had a history of over night wearing of contact lens. The size of corneal ulcer varied from 1 to 8 mm in the longest diameter. Hypopyon was seen in 80% of patients. Almost all P. aeruginosa were resistant to ampicillin, cephalothin, chloramphenicol, and carbenicillin, but susceptible to imipenem, ciprofloxacin, and piperacillin. CONCLUSION: Pseudomonas keratitis is a rapidly spreading ulcer with various complications. It has markedly increased in contact lens wearers. To prevent further increase, education, early diagnosis, and treatment are important.
