The short time antibacterial effect of tetracaine hydrochloride was studied. S. aureus, Coagulase Negative Staphylococcus and P. aeruginosa were each incubated with tetracaine hydrochloride(preservative free) for 18 hours or for 2 minutes and then diluted and cultured on nutrient agar plate. Colony counts were done after 18 hours. In cases of 18 hours incubation, there was no growth of microbials in 0.5%, 0.1% tetracaine hydrochloride, but there was no inhibitory effect of 0.02% of tetracaine hydrochloride on growth of microbials, irrespective of inoculum amount. In cases of 2 minutes incubation with 0.5% tetracaine hydrochloride, there was no difference between the amount of microbial inoculum and colony count. Above in vitro study indicates that tetracaine hydrochloride has no inhibitory effect on bacterial growth in short time exposure less than 2 minutes.

The bacterial group which we usually consider as resident flora sometimes changes into opportuniistic pathogen which produces oppartunistic infection, so that attention to resident flora remarkably increased. The main topics of bacterioloical problems of skin flora are as follows: (1) selective localization of resident flora, (2) members of resident flora and their changes by age and area, (3) the role of action of resident flora, (4j the problems of Micrococcus, (5) coagulase negative Staphylococci, (6) coagulase positive Staphylococci, (7) the problerns of Propionilbacterium(P) acnes, (8) typing of propionibacteria existing on human skin, (9) antibiotic sensitivities of P. acnes, (10) effect of tetracycline on lipase productivity oi P. acnes.

BACKGROUND: Teicoplanin is a glycopeptide antimicrobial agent effective against methicillin-resistant staphylococci. Decreased susceptibility of staphylococci to glycopeptides has been increasing. Teicoplanin diffuses poorly in agar and therefore the correlation between the inhibition zone diameter and the minimal inhibitory concentration(MIC) is rather poor. The purpose of this study was to evaluate the prevalence of teicoplanin-resistant staphylococci and to assess the reliability of inhibition zone diameters for determining the susceptibility of staphylococci to teicoplanin by comparing the results of the agar dilution MICs. METHODS: From June to August 1997, 290 clinical isolates of staphylococci(77 coagulase negative staphylococci(CNS), 213 Staphylococcus aureus) were collected. The antimicrobial susceptibilities to teicoplanin were determined by inhibition zone diameter and the results were compared with the MICs determined by the agar dilution method. RESULTS: Among 77 CNS strains, 75(97.4%) were susceptible and 2(2.6%) were intermediate by agar dilution method and all 213 strains of S. aureus were susceptible to teicoplanin. There was a poor correlation(r=0.50) between the zone diameters of inhibition and agar dilution MICs. In comparison with the results of disk diffusion test and agar dilution MIC, eight (2.8%) out of 290 isolates showed discrepancies (major error rates : 0.3%, minor error rates: 2.4%). CONCLUSIONS: Two(2.6%) out of 77 strains of CNS and none of 213 S. aureus strains revealed decreased susceptibility to teicoplanin. And the inhibition zone diameter was less reliable in determining the susceptibility of staphylococci than MICs. Therefore, the more effective and convenient method is needed.

Sepsis is a significant cause of mortality and morbidity in the neonates. This article reviews the studies which analyzed the causative pathogens of neonatal sepsis in Korea. The changes of bacterial pathogens in other countries are reviewed. This review also introduces the recent updates of preventive and immunotherapy in neonatal sepsis. Coagulase negative staphylococci and Staphylococcus aureus were the most commonly isolated organisms in the early and late onset neonatal sepsis in Korea. Group B streptococcus was a rare cause of the early onset disease in Korea. To obtain a more accurate data, prospective nationwide surveillance will be warranted.

Conjunctival bacterial cultures for 113 neonates who were delivered by cesarean section or vaginal delivery were performed within 30 minutes after birth. These neonates were in the condition of no eye drops applied. The 43 newborns were delivered by cesarean section(CS group) and the 70 newborns were delivered vaginally(VD group). The 10 newborns(P1) (14 eyes(P2)) in the CS group and the 29 newborns(41 eyes) in the VD group showed culture positivity. These differences between two groups were statistically significant(p1, p2<0.05). The CS group had significantly fewer species and colony forming units cultured per subject (0.395 +/- 0.821(p3), 5.116 +/- 27.095(p4) than the VD group(0.971 +/- 1.393, 25.843 +/- 62.285) (p3,p4<0.05). Coagulase negative staphylococci were predominantly isolated in the CS group and coagulase negative staphylococci, gram positive bacilli, E. coli, nonfermenting bacilli, and S. aureus in the VD group. Therefore it was found that the conjunctiva of the newborns delivered by cesarean section bore significantly fewer bacteria and need less prophylactic measures than that of newborns delivered vaginally.

Bacteriological study, including antibiotic sensitivity tests, of 81 patients with pyodermas such as impetigo, folliculitis, furuncle, carbuncle, cellulitis and acuete infectious eczematoid dermatitis, was carried out during 4 months period from June, 1980 to September, 1980 at the department of dermatology, Han Il Hospital. The results were as follows: 1) The causative agents of impetigo in 42 patients, were coagulase positive Staphylacoccus aureus in 33, p-hemolytic Streptococcus in 6 and both organisms in R (S. aureus and 3-hemolytic Streptococcus). Coagulase negative Stgaphylococcus was not found. 2) The causative agents of superficial and deep follicultis in 23 cases, were coagulase positive S. aureus in 12, coaulase negative Staphylococcus in 5, p-hemolytic Streptococcus in 4 and S. aureus and p-hemolytic Streptococcus in 3. 3) The causative agents of cellulitis in 2 cases, were coagulase positive S. aureus in 1, and coagulase negative Staphylococcus in 1. 4) The causative agents of acute infectious eczematoid dermatitis in l4 cases, were coagulase positive S. aureus in 6, coagulase negative Staphylococcua in 1, p-hemolytic Streptococcus in 2, and two organisms in 5 (4 cases were mixed).

We reported a case of 22 years old male with perifolliculitis capitis abscedens et suffodiens. He had multiple fistular tracts, abscess, and cicatrized alopecia on the vertex and occiput. Compressing the abscess lesion, pus discharge was shown. Also he had acne conglobata and acne vulgaris on the face and nuchal area. On the bacterial culture, coagulase positive Staphylococcus aureus was isolated. These lesions were persistent in spite of frequent incision and drainage and antibiotic therapy. Considering it having a pathogenesis like acne conglobata, we tried him 13-cis-retinoic acid that had good effect in the treatment of cystic or conglobate acne. Three months after treatment, the lesions disappeared completely.

The hyperimmunoglobulin E syndrome is a primary immunodificiency disorder characterized by recurrent staphylococcal infections and markedly elevated serum IgE level. Clinical features are coarse face and severe infections of the skin-furunculosis or chronically pruritic dermatitis and sinopulmonary tract infection from infancy by coagulase positive Staphylococcus aureus, or Candida albicans etc. The patients's serum IgE level is elevated but the basic immunologic pathogenesis not fully understood. We have experienced a case of hyperimmunoglobulin E syndrome in a 26/12-year-old who had suffered from recurrent staphylococcal pneumonias and abscesses and chronically pruritic dermatitis from 1 month of age with elevated serum IgE level. A brief review of the related literature is presented.

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.
