Abstract

ABSTRACTThe aim of this study was to get cytomegalovirus viruria prevalence data in healthy adultpopulation. Urine samples were obtained from healthy individuals. Preparation of sample and sera(polyclonal antibody) were performed by standard method., and detection of cytomegalovirusantigen in urine sediment were done by Indirect Immunofluorescence Antibodi Technique (IFAT).The results were analyzed with chi square pearson. From 341 healthy individuals (16 ♀ and 125 ♂)age between 18 to 61 years. Cytomegalovirys viruria were found in 5 (3, 55%) of subjects. In groupof subjects less than 30 years of age, cytomegalovirus viruria were found in 3,82% subject whereasin group of subjects more than 30 years of age, cytomegalovirus viruria was not found; chi squarepearson statistic analysis did not show significant difference between two groups (p = 0,529). Ingroup of women, cytomegalovirus viruria were found in 6,25% subjects whereas in group of men,cytomegalovirus viruria were found in 3,2% subjects; chi square pearson statistic analysis did notshow significant difference between two groups (p = 0,535). Cytomegalovirus viruria prevalenceamong healthy adult population studied was relatively low (3,55%).Key words: Cytomegalovirus, viruria, prevalence, latent infection, Indirect ImmunofluorescenceAntibodi Technique (IFAT)

Abstract

Background: Traditional medicine has been widely used in our community and many of them were found to be effective in the treatment of various diseases. Previous studies showed that Phyllanthus niruri L. has an effect as immunostimulator and antiviral activities.Objective: The aim of this study was to evaluate the efficacy of Phyllanthus niruri L. in the treatment of skin infection caused by Staphylococcus aureus.Materials and Methods: Thirty mice of Swiss strain were infected with 2x100 colony forming unit of S.aureus subcutaneously. The mice were then devided into 3 groups; Phyllanthus niruri L.-treated group, cotrimoxazole-treated group, and control group. Treatmen

Abstract

Traditional medication has been used by Indonesian people since long time ago and still continuing up to the present time. Many of them proved to be effective in curing various diseases. In this study an in vitro activity of Momordica charantia againts Herpes Simplex Virus type 2 has been evaluated by standard method of plaque reduction assay. The aim of this study is to determine whether traditional medicine we are searching has an antiviral activity. The results showed that total inhibition of plaque formation on HSV 2-infected Vero cell line was achieved at concentration of 8% v/v of crude extract, whereas the concentration of 1% v/v was capable of reducing the number of plaques by approximately 50% (inhibitory dose50= ID50). These results were very interesting as even with only small amount of crude extract we could get ID50. We expect that much lower concentration will be required to obtain ID50 if we use purified extract in the assay. Further studies are needed to elucidate other properties of the extract, including its in vivo antiviral activity, possible effect on other viruses, and mechanism of action.Key words: antiviral activity - herpes simplex virus - Momordica charantia - traditional medicine - plaque reduction assay

Abstract

Nontuberculous mycobacteria (NTM) adalah mikrorganisme yang banyak dijumpai di lingkungan, namun, baru-baru ini dianggap patogen karena kejadian infeksinya meningkat secara signifikan. Penelitian ini bertujuan untuk mengetahui kemampuan pembentukan biofilm isolat NTM, korelasinya dengan sifat motilitas geser, dan untuk menganalisis pola kepekaan antibiotik. Strain NTM yang dipakai dalam penelitian ini adalah 10 isolat klinis NTM yang diperoleh dari laboratorium TB, Departemen Mikrobiologi, Fakultas Kedokteran UGM Yogyakarta. Kemampuan pembentukan biofilm dideteksi dengan menggunakan uji mikrotiter dan pewarnaan dengan kristal violet 1%. Uji motilitas geser dilakukan pada medium motilitas, terdiri dari 0,3% Middlebrook 7H9-agar tanpa suplemen. Pola kepekaan antibiotik diteliti dengan teknik dilusi sesuai metode CLSI. Dari penelitian ini menunjukkan bahwa 7 dari 10 isolat NTM merupakan penghasil biofilm kuat, sementara 1 isolat sebagai strain penghasil biofilm moderat, dan 2 isolat tidak menghasilkan biofilm. Sementara itu, strain pembentuk biofilm mampu melakukan motilitas geser pada agar semisolid, dan 2 isolat NTM yang tidak memiliki kemampuan pembentukan biofilm tidak dapat melakukan motilitas geser. Sifat pembentukan biofilm berkorelasi dengan kemampuan isolat NTM untuk melakukan motilitas geser pada media agar semisolid. Klaritromisin merupakan antibiotik yang paling efektif terhadap isolat NTM yang diuji (poten terhadap 50% isolat uji), diikuti oleh gentamisin (40%), sedangkan kanamisin, levofloxacin, dan ofloxacin menunjukkan tingkat potensi yang sama (30%). Ceftriaxone hanya mampu menghambat pertumbuhan isolat NTM sekitar 20%. Selanjutnya, kotrimoksazol dan amoksisilin memiliki aktivitas in vitro yang buruk terhadap isolat NTM karena tidak ada isolat NTM yang sensitif terhadap kedua antibiotik ini. Nontuberculous mycobacteria (NTM) are ubiquitous organisms commonly found in the environment. However, recently it is considered as emerging global interest since the incidence increase significantly. This study aimed to investigate the biofilm forming ability of NTM isolates, correlated with the sliding motility properties, and to analyze their antibiotic susceptibility pattern. NTM strain included in this study were 10 NTM clinical isolates obtained from TB laboratory, Microbiology Departement, Faculty of Medicine UGM Yogyakarta. Biofilm forming capability was detected by using biofilm development assay in microtiter plate and staining with 1% crystal violet. Sliding motility assay was performed on motility medium, consisting of Middlebrook 7H9- 0.3% agar without supplements. Antibiotic susceptibility pattern was investigated by macrobroth dilution technique according to CLSI methods. Our study revealed that 7 out of 10 NTM isolates produced biofilm strongly, while 1 isolate demontrated as moderate biofilm former strain, and the remaining 2 isolates did not produce biofilm on polysterene substrate. Meanwhile, biofilm-former strain are able to slide on semisolid agar, and 2 non-adherent NTM isolates did not have ability to perform sliding motility. A good correlation was found between mycobacterial sliding and biofilm assembly of NTM isolates. Clarithromycin has been shown as the most effective antibiotic against NTM isolates tested, which was active against 50% of all isolates, followed by gentamycin (40%), while kanamycin, levofloxacin, and ofloxacin showed the same level of potency (30%). Ceftriaxone was only able to inhibit the growth of NTM isolates about 20%. Furthermore, cotrimoxazole and amoxicillin had poor in vitro activity against NTM species.
