Macrolide Resistance of Mycoplasma pneumoniae and Its Detection Rate by Real-Time PCR in Primary and Tertiary Care Hospitals

BACKGROUND: This study aimed to evaluate the prevalence of Mycoplasma pneumoniae in primary and tertiary care hospitals and its macrolide resistance rate. METHODS: Nasopharyngeal swabs were collected from 195 pediatric patients in primary and tertiary care hospitals from October to November 2010. The AccuPower MP real-time PCR kit (Bioneer, Korea) was used for the detection of M. pneumoniae. Direct amplicon sequencing was performed to detect point mutations conferring resistance to macrolides in the 23S rRNA gene. RESULTS: Among the 195 specimens, 17 (8.7%) were M. pneumoniae positive, and 3 of the strains (17.6%) obtained from these 17 specimens displayed the A2063G mutation in 23S rRNA. Three macrolide-resistant M. pneumoniae isolates were isolated from patients hospitalized at the primary care hospital. The positive rates of M. pneumoniae for the primary and tertiary care hospitals were 12.1% (15/124) and 2.8% (2/71), respectively (P=0.033). CONCLUSIONS: The positive rate of M. pneumoniae in the primary care hospital was higher than that in the tertiary care hospital. Simultaneous detection of M. pneumoniae and macrolide-resistant mutation genes in the 23S rRNA by real-time PCR is needed for rapid diagnosis and therapy of M. pneumoniae infections.

Colonization Rate, Serotypes, and Distributions of Macrolide-Lincosamide-Streptogramin(B) Resistant Types of Group B Streptococci in Pregnant Women / 대한임상미생물학회지

BACKGROUND: The prevalence of neonatal group B streptococcal infection depends mainly on the colonization rate of pregnant women by group B streptococci (GBS). Although the colonization rate of Korean women by GBS is considered lower than in other countries, recent data on the maternal colonization rate of GBS are sparse. METHODS: From August 2008 to June 2009, swab specimens from the anorectus, vagina, and urethral orifice of a sample of 234 pregnant Korean women were placed in new Granada medium (NGM-H), tube medium (NGM-T), commercial NGM (NGM-B), and selective Todd-Hewitt broth (S-THB) for 18~24 hours in 5% CO2 at 35degrees C. Agar dilutional antimicrobial susceptibility tests, serotyping, and PCR were performed for GBS isolates. RESULTS: The colonization rate of GBS in pregnant women was 11.5% (27/234). Of the specimen cultures, 9.8% of anorectal cultures were positive, 8.1% of urethral orifice cultures were positive, and 7.3% of vagina cultures were positive. The detection rate of GBS in the different culture media was S-THB (96.3%), NGM-B (92.6%), NGM-H (88.9%), and NGM-T (85.2%). The distribution of GBS serotypes was as follows: III (29.6%), V and VI (22.2%), Ib and II (11.1%), and Ia (3.7%). 33.3% of GBS isolates were resistant to erythromycin and 44.4% to clindamycin. Among the nine erythromycin-resistant isolates, eight were serotype V and VI, which are erm(B) positive serotypes. CONCLUSION: The colonization of pregnant women by GBS, and the incidence of resistance of the GBS isolates to erythromycin and clindamycin were higher than those previously reported. Serotypes V and VI, GBS serotypes that carry the erm(B), are novel serotypes that have not previously been identified in pregnant Korean women.

Macrolide Resistance Trends in beta-Hemolytic Streptococci in a Tertiary Korean Hospital

PURPOSE: Erythromycin-resistant beta-hemolytic streptococci (BHS) has recently emerged and quickly spread between and within countries throughout the world. In this study, we evaluate the antimicrobial susceptibility patterns and erythromycin resistance mechanisms of BHS during 2003-2004. MATERIALS AND METHODS: The MICs of seven antimicrobials were determined for 204 clinical isolates of BHS from 2003 to 2004. Resistance mechanisms of erythromycin-resistant BHS were studied by the double disk test as well as by polymerase chain reaction (PCR). RESULTS: Compared with our previous study, resistance among Streptococcus pyogenes isolates to a variety of drugs decreased strikingly: from 25.7% to 4.8% in erythromycin; 15.8% to 0% in clindamycin; and 47.1% to 19.0% in tetracycline. The prevalent phenotypes and genotypes of macrolide-lincosamide-streptograminB (MLSB) resistance in Streptococcus pyogenes isolates have been changed from the constitutive MLSB phenotype carrying erm(B) to the M phenotype with mef(A) gene. In contrast with Streptococcus pyogenes, resistance rates to erythromycin (36.7%), clindamycin (43.1%), and tetracycline (95.4%) in Streptococcus agalactiae isolates did not show decreasing trends. Among the Streptococcus dysgalactiae subsp. equisimilis isolates (Lancefield group C, G), resistance rates to erythromycin, clindamycin, tetracycline and chloramphenicol were observed to be 9.4%, 3.1%, 68.8%, and 9.4%, respectively. CONCLUSION: Continual monitoring of antimicrobial resistance among large-colony-forming BHS is needed to provide the medical community with current data regarding the resistance mechanisms that are most common to their local or regional environments.

The Effect of the Plasma Treatment on PLGA Scaffold for Adhesion and Chondrogenic Differentiation of Human Adipose-derived Stromal Cells

High-density micromass culture was needed to take three dimensions culture with ASCs(adipose derived stromal cells) and chondrogenesis. However, the synthetic polymer has hydrophobic character and low affinity to cells and other biomolecules. Therefore, the surface modification without changes of physical and chemical properties is necessary for more suitable condition to cells and biomolecules. This study was performed to investigate the effect of surface modification of poly (lactic-co-glycolic acid)(PLGA) scaffold by plasma treatment (P(+)) on the adhesion, proliferation and chondrogenesis of ASCs, and not plasma treatment (P(-)). ASCs were isolated from human subcutaneous adipose tissue obtained by lipectomy and liposuction. At 1 hour 30 minutes and 3days after cell seeding onto the P(-) group and the P(+) group, total DNA amount of attached and proliferated ASCs markedly increased in the P(+) group (p < 0.05). The changes of the actin under confocal microscope were done for evaluation of cellular affinity, at 1 hour 30 minutes, the shape of the cells was spherical form in all group. At 3rd day, the shape of the cells was fiber network form and finely arranged in P(+) group rather than in P(-) group. RT-PCR analysis of cartilage-specific type II collagen and link protein were expressed in 1, 2 weeks of induction. Amount of Glycoaminoglycan (GAG) markedly increased in P(+) group(p < 0.05). In a week, extracellular matrix was not observed in the Alcian blue and Safranin O staining. However in 2 weeks, it was observed that sulfated proteoglycan increased in P(+) group rather than in P(-) group. In conclusion, we recognized that plasma treatment of PLGA scaffold could increase the hydrophilic property of cells, and provide suitable environment for high-density micromass culture to chondrogenesis.

A Case of Cowden Disease Associated with Lhermitte-Duclos Disease / 대한소화기내시경학회지

Cowden disease (CD), also known as 'multiple hamartoma syndrome', is a rare autosomal dominant disorder with a high risk of breast, thyroid, or genitourinary malignancies. Lhermitte-Duclos Disease (LDD) is believed to be a hamartomatous overgrowth of cerebellar ganglion cells and currently is considered to be a part of CD. However, the report of the association between LDD and CD has been very unusual. We have recently experienced a 53-year-old man with LDD who had acral keratosis of extremities, gastrointestinal polyposis, and multinodular goiter. To our knowledge, it is the second case of CD associated with LDD in Korea. We report it with a review of the literatures.

A Case of Henoch-Schonlein Purpura Associated with Gastric Ulcer Bleeding / 대한소화기내시경학회지

Henoch-Schonlein purpura is a systemic leukoclastic vasculitis that predominantly affects small vessels. This results in purpura, abdominal pain, arthralgia and occasional sometimes nephritis. Gastrointestinal involvement occurs in 50~75% of the patients. The small bowel and colon are relatively commonly affected, but the gastric involvement is rare. Endoscopic findings include mucosal edema, hemorrhagic changes, erosions and superficial ulcers. However, deep gastric ulcers are rarely observed in Henoch-Schonlein purpura and have not been reported yet. We report a patient with typical Henoch-Schonlein purpura who presented with melena due to bleeding from multiple deep gastric ulcers and got improved with administration of high dose corticosteroid.

Preadipocyte Culture in Chitosan-Alginate Gel

Alginate gel is widely used as a scaffold in tissue engineering. Alginate solution has anionic properties, and calcium or magnesium cation has been used to crosslink alginate into a gel form. Chitosan not only has cationic properties but also is known to promote wound healing. Although there are some studies of chitosan- alginate gel use in drug delivery, reports of its application as a scaffold in tissue engineering are rare. The purpose of this study is to make chitosan-alginate gel and to investigate its biocompatibility as a scaffold for preadipocyte culture. 1, 2, 4, 6% chitosan solutions were mixed with 2% alginate solution to make various concentrations of chitosan-alginate gels. All of the gel which were made have been measured by Viscometer. Preadipocytes obtained from human breast fat tissue were seeded into each chitosan-alginate gel, and cell viability was measured by XTT colorimetric assay on the 2th, 4th, and 7th day of preadipocyte culture. The results of analysis were as follows. Each viscosity of 4% and 6% chitosan-alginate gels is similar to that of the calcium-alginate gel and 4% and 6% chitosan-alginate gels shows significantly higher cell viability than the calcium-alginate gel(p<0.05). In conclusion, chitosan-alginate gel is thought to be an appropriate scaffold for preadipocyte culture in tissue engineering.

Identification System of Nonfermentative Gram Negative Bacilli Using Microplate / 대한임상미생물학회지

BACKGROUND: The accurate and rapid identification (ID) of nonfermentative gram-negative bacilli (NFB) is essential for diagnostic and therapeutic purposes and for epidemiologic studies of hospital infections. Commercial identification systems of NFB are easy to use but too expensive. The aim of the study was to develop a simple system for the identification of NFB species which are frequently isolated from clinical specimens. METHODS: Eighteen biochemical tests used in NFB microplate ID system were pyocyanin in Tech media; pyoverdin in Flo media; glucose fermentation, acid formation from glucose, maltose, lactose, sucrose, and mannitol in oxidation-fermentation media; Nitrate and nitrite reduction in nitrate media; fornithine decarboxylase, lysine decarboxylase, and arginine dihydrolase in Moeller decarboxylase media; acetamide, urease, citrate, 42degrees C growth, and oxidase test. For the establishment of NFB's biochemical data in microplate ID system, 175 consecutive isolates of NFB from clinical specimens isolated during the period of April 2000 were simultaneously tested by microplate method and API 32GN. RESULTS: Ninety-two percent of clinical isolates of NFB were identified to the species level by NFB microplate ID system. CONCLUSIONS: The NFB microplate ID system is simple to use, rapid and economical. Further modification are needed to improve the accuracy and identification rate of NFB isolates.

Usefulness of a Disk Method for Detection of Hippurate Hydrolysis by Campylobacter jejuni / 대한임상미생물학회지

BACKGROUND: The test for hippurate hydrolysis is critical for differentiation of C. jejuni and other thermophilic Campylobacter species. So, we evaluated the disk method for detection of hippurate hydrolysis by C. jejuni. METHODS: Twenty-eight Campylobacter species isolated from stool culture were simultaneously tested with disk method for detection of hippurate hydrolysis and polymerase chain reaction (PCR) for hippuricase specific gene. Disk method was tested with difference in incubation time (2 hours vs. 4 hours), hippurate concentration (1%, 2%, and 4%), amount of ninhydrin (50 microliter vs. 100 microliter), and inoculation method (colony vs. suspension of organism adjusted by turbidity), finally, 24 types of disk methods were performed. RESULTS: By using hippuricase PCR method as the reference for the detection of hippurate hydrolysis, the disk method showed a sensitivity of 91.7% and a specificity of 100% when two kinds of disk methods were simultaneously performed. CONCLUSIONS: The disk method for detection of hippurate hydrolysis is simple to use and require fewer cells than the tube method do, and should be useful as a routine diagnostic test in clinical laboratory for rapid identification of C. jejuni.

A Case of Septicemia by Plesiomonas shigelloides / 대한임상미생물학회지

Plesiomonas shigelloides is an oxidase-positive, fermentative, gram-negative rod currently classified as a member of the family Vibrionaceae. P. shigelloides has been implicated as the causative agents of gastroenteritis as well as extraintestinal infections such as septicemia, neonatal meningitis, cellulitis, and cholecystitis. Septicemia due to P. shigelloides is very rare but is severe and has been associated with a high mortality rate. We report a case of septicemia caused by P. shigelloides in a 66-year-old male with diabetes mellitus who had diagnosed as liver cirrhosis 7 years before.

Identificatiion,Antimicrobial Susceptibility an Epidemiology of Klebsiella species Isolated from Clinical Specimen / 대한임상미생물학회지

BACKGROUND: In recent years, the incidence of extended-spectrum beta-lactamase (ESBL) producing Klebsiella has been steadily increased, and the newer species K. planticola and K terrigena, formerly regarded as nonpathogen, have been reported with astonishing frequency from human infectious processes by some investigators. The aim of this study is to elucidate the isolation rate and antimicrobial susceptibility of recent clinical Klebsiella isolates. METHOD: For the clinical Klebsiella isolates during the period of June 1999 to May 2000, isolation frequency of Klebsiella species by specimen, departments, age, and sex were analyzed. And antimicrobial susceptibilities were also analyzed. RESULT: Isolation rate of Klebsiella in order of decreasing frequency were K. pneumoniae (74:7%), K. oxytoca (12.1%), K. ozaenae(1.7%), K. planticola(1.0%), K. terngena(0.9%), and K, ornithinolytica (0.7%), respectively. K. rhinoscleromatis was not isolated. Compared with outpatients, increase of resistance rates of inpatients's Klebsiella isolates were 10% in ciprofloxacin, 15% in cefoperazone/sulbactam, and the others were ranged from 24% to 31%. Isolation rate of ESBL producing K. pneumoniae by double disk (DD) synergy test was 41%, and detection rates by antimicrobial agents were as follows: cefotaxime (95%), aztreonam (58%), and ceftriaxone (37%). Antimicrobial susceptibility rate with the exception of ampicillin and imipenem decreased from the range of 81%-96% on admission day to 29-62% after one week on admission. CONCLUSION: The isolation rates of K. planticola and K. terrigena were less than 1%. The proportion of ESBL producing K. pneumoniae was 41 %. And the vast majority of multidrug resistant Klebsiella including ESBL producing strains are acquired by hospitalization.

Rapid Detection of Mycobacteria usin Mycobacteria Growith Indicator tube(MGIT)and Ogawa Media / 대한임상미생물학회지

BACKGROUND: As many as several weeks of incubation may be necessary for the recovery of mycobacteria when conventional culture media are used. Previous studies evaluating Mycobacteria Growth Indicator Tube (MGIT) as a rapid for the growth and detection of mycobacteria from clinical specimens have been reported. We compared MGIT with Ogawa media for the recovery of mycobacteria from clinical specimens. METHODS: Ninety nine clinical specimens received in the laboratory of Wonju Christian Hospital from June to September 199 were used for this study. The specimens from nonsterile body sites were digested, decontaminated, and concentrated, for culture and Ziehl-Neelsen stain, and specimen were inoculated onto MGIT tube and 3% Ogawa egg medium, and cultured for 8 weeks. RESULTS: Of the 38 specimens culture-positive for mycobacteria, 3 grew isolates in MGIT medium only, 8 grew isolates in Ogawa media only, and 27 grew isolates in both media. Mean (median, range) times to detection of mycobacteria were 13.7 (5.5, 2-48) days with MGIT and 19.6 (18, 13-37) days with Ogawa (P>0.05). The number recovered with MGIT plus Ogawa media was 24 (63.2%) within 14 days of receipt of specimen, and 31 (81.6%) within 21 days. The contamination rates were 31 % for MGIT and 1 % for Ogawa media. CONCLUSIONS: MGIT appears useful to quickly detect and identify mycobacteria from clinical specimens. However, because the number of culture-positive specimen in MGIT was not greater than those recovered with Ogawa media, MGIT should be used in combination with solid media to reduce turnaround times and increase the isolation rate.

Anti-Cancer Efficacy of Anti-CEA IgG3 in a Syngeneic Carcinoembryonix Antigen Tumor Model / 대한면역학회지

Development of antibody-based cancer therapies will be greatly facilitated if antibodies are better standardized in two fundamental issues that are specificity analysis of antibody reactivity and the detailed biodistribution and pharmacokinetic profile of antibodies. In the current endeavor we attempted to use an antibody binding specificity to target the tumor in a syngeneic carcinoembryonic antigen (CEA) tumor model. CEA, a 180 kDa glycoprotein, expressed at high levels on the surface of nearly all tumors of the gastrointestinal tract was used a potential target for antibody immunotherapy of gastrointestinal carcinomas. Using the CEA model antibody-based cancer therapy directed against CEA has been evaluated in a syngeneic animal model of disseminated disease. We constructed mouse/human chimeric anti-CEA IgG3, which has been evaluated for the specificity for CEA and the detailed biodistribution and pharmacokinetic profiles. Anti-CEA IgG3 heavy chain was expressed with the expected 180kDa molecular weight, assembled as H2L2 forms with a co-expressed mouse/human chimeric anti-CEA light chain, and were secreted. On FACS the purified anti-CEA IgG3 specifically recognized the mouse colon adenocarcinoma cell line MC-38 transduced with CEA (MCA32a), but not MC 38 without expressing CEA. After subcutaneous injection in C57BL/6 mice the half- lives of anti-CEA IgG3 and an irrelevant anti-dansyl IgG3 showed the bi-phasic kinetic patterns, and their pharmacokinetics of the distribution and the elimination were similar in mice. However, the biodistribution patterns of anti-CEA IgG3 were very different from those of anti-dansyl IgG3. Anti-dansyl IgG3 was mainly distributed into kidney until 72 hours, but anti-CEA IgG3 was slowly rernoved from blood and distributed into liver, kidney, spleen, and tumor. It is note worthy that anti- CEA IgG3 increased in targeting MCA32a tumor expressing human CEA by time, but the targeting to MC38 tumor was negligible. Thus, the increased targeting of anti- CEA IgG3 made MCA32a tumor grow slowly

Affinity Improvement of Antibody-Avidin Fusion Proteins for Biotin / 대한면역학회지

To generate drug delivery vector to locales in the body, genetic engineering and expression techniques have been used to produce antibody avidin fusion proteins. Chicken avidin has been fused to mouse-human chimeric IgG3 immediately after the hinge with a flexible linker (H-Flex-Av) and at the end of CH2 (CH2-Av). Fusion heavy chains were expressed with the expected molecular weight, assembled as H2L2 forms with a co-expressed light chain, and were secreted. The expression level of H- Flex-Av was 1~10 ug/ml/10(8)/24 hrs, but that of C2-Av was a very little (0.08~0.9 ug/ ml/10(8)/24 hrs). The resulting H-Flex-Av and CH2-Av fusion proteins continued to bind antigen dansyl and also bound biotinylated bovine serum albumin; both H-Flex-Av and CH2-Av had shown to retain 3-4 times higher relative affinity than that of CH3-Av in ELISA. Importantly the fact that both avidin fusion proteins had a higher relative affinity suggests that these avidin fusion proteins can be effectively used to deliver biotinylated ligands such as drugs and peptides to a certain locale, such as the brain.

Endoscopically Removed Polypoid Esophageal Leiomyoma / 대한소화기내시경학회지

Leiomyoma is the most common benign tumor of the esophagus, but it still occurs rarely, as compared with the incidence of cacinoma. There are no geographic or racial differences and manifestations are unusual and inconsistent. About 97% of the esophageal leiomyoma may oecur in intramural type and 1 of the tumor may be polypoid type. Considerable diagnostic problems may arise as well as problems of proper surgical management. We experienced a case of a 47-year old female with esophageal leiomyoma in the mid- point of the esophagus. The patient complained of substernal discomfort for 1 month and routine examinatian and gastrofiberscope were performed. The gastrofiberscopic finding was asmoothly protruded, round bean-sized polypoid mass in the midpoint of the esophagus which was removed by polypectomy. There were no other complications. So we reported this case with review of literature.
