Abstract

Pneumonia is one of the lower respiratory tract infection involving respiratory bronchioles and alveoli that mostly caused by Streptococcus pneumoniae.Clindamycin is one of the drug of choice for pneumoniae. This drugs inhibits the growth of S. pneumoniae by producing ROS (Reactive Oxygen Species). Recent study has shown that vitamin C could generate ROS leading to DNA-damage on bacteria. The aims of this study was to know the possible benefit effect of adding vitamin C towards clindamycin inhibition activity against the growth of S. pneumoniae in vitro. This research was conducted by using 7 groups which consist of negative control (aquades), positive control (clindamycin), and test group 1 until 5 that given the combination of clindamycin and vitamin C as follows 2,5 mg/ml; 5 mg/ml; 10 mg/ml; 20 mg/ml; and 40 mg/ml. The inhibition effect of growing S. pneumoniae shown by the inhibition zone diameter. The average of inhibition zone on negative control, positive control, and test group were 5; 24,12; 24,62; 26,08; 27,58; 28,74; and 29,76 mm. These result show a significant correlation based on Pearson test (the coefficient correlation’s result is +0,910). The logarithmic regression revealed the minimal concentration of vitamin C was 1,767 mg/ml. It can be concluded that vitamin C increased the activity of clindamycin by inhibiting the growth of S.pneumoniae in vitro. Keywords: Streptococcus pneumoniae, ROS, Clindamycin, Vitamin C

Abstract

Pneumonia is the main common cause of children death in the world. Microbiological studies found the major causes of pneumonia is Streptococcus pneumoniae. Infection of S.pneumoniae influenced by several virulence factors, one of which is surface protein. The purpose of this study was to determine the immunogenicity of 19 kDa S.pneumoniae surface protein through hemagglutination inhibition and adhesion inhibition test. Adhesion inhibition test used antibodies that is formed from surface protein, to inhibit bacterial adhesion to the enterocytes. Hemagglutination inhibition test also used antibodies that formed from surface protein, to inhibit the agglutination of erythrocytes caused by S.pneumoniae. The results showed that antibodies, which was formed from 19 kDa S.pneumoniae surface protein, were able to inhibit hemagglutination process up to 1X dilution. Adhesion inhibition test showed that the higher antibody dilution, the greater the adhesion index. Pearson correlation analysis of the adhesion test showed that there was a significant correlation between antibody dilution with bacterial adhesion index (R= -0,787; p=0,036). It can be concluded that the 19 kDa surface protein of S.pneumoniae was immunogenic.   Keywords: Streptococcus pneumoniae, surface protein, antibody

Abstract

Nephrotoxicity due to prolonged use of vancomycin becomes a big issue in patients with MRSA infections and the use of vitamin C has been proved to decrease this side effect. Vitamin C with its combination with antibiotic will halt MRSA growth by forming Reactive Oxygen Species (ROS). This study aimed to determine the effect of vancomycin and vitamin C combination in order to halt the MRSA growth and the minimum concentration of vitamin C which can decrease the Minimum Inhibitory Concentration (MIC) of vancomycin. This study used a quasi experimental design with 7 groups, 1 as negative control which only given vancomycin and 6 other groups which given vancomycin and vitamin C with following concentration 0,4; 0,8; 1,6; 3,2; 6,4; and 12,8 mg/mL. We used microdilution method with 4 repetitions to measure the MIC value. This study revealed that there were no difference between control and other groups, the MIC of vancomycin is 1 µg/mL. Combination effect was measured by Fractional Inhibitory Concentration Index (FICI) calculation which showed indifferent effect to all groups. This study concluded that combination of vancomycin and vitamin C effect has no difference with control group and by adding vitamin C until 12,8 mg/mL did not decrease MRSA growth. Keywords: MRSA, vancomycin, vitamin C, Minimum Inhibitory Concentration (MIC)

Abstract

yphoid fever is an acute infectious disease in the intestinal tract caused by Salmonella typhi. The prevalence of typhoid fever in Indonesia in 2013 was 81% per 100,000 population. Ciprofloxacin is a large-spectrum antibiotics, but in some countries ciprofloxacin has been known to be resistant to S. typhi. Therefore, other methods are needed to improve the effectiveness of ciprofloxacin by combining with chitosan. Chitosan is a polysaccharide which known to be effective in some positive and negative Gram bacteria and able to overcome the resistance of some antibiotics. The research objective was to determine the effect of antibacterial and Minimum Inhibitory Concentration (MIC) of the combination of Litopenaeus vannamei chitosan and ciprofloxacin against S. typhi. The method used to obtain the value of the MIC was microdilution method with quasy-experimental research design and posttest only control group design. MIC which already been obtained then used to find the Fractional Inhibitory Concentration Index (FICI) using a checkerboard test to interpret the effect of the combination. The MIC combination showed different results in each repetition that chitosan: 15.63 to 62.5 µg/mL and ciprofloxacin from 0.03 to 0.5 µg/mL and known to have a smaller value than the MIC single. While the value of FICI from 5 repetitions was 0.476. So, it could be concluded that the combination of chitosan and ciprofloxacin has an antibacterial effect on S. typhi and have a synergistic combination effect. Keywords: Salmonella typhi, chitosan, ciprofloxacin, microdilution method, checkerboard test.

Abstract

Tuberculosis (TB) and soil-transmitted helminth (STH) infections are infectious diseases with a high prevalence in Indonesia. STH co-infection in TB patients can worsen the prognosis of TB disease due to the dysregulation of the immune response. The high prevalence of STH infections in Indonesia is caused by environmental factors such as poor personal hygiene habits. Jenggawah Subdistrict is an area with a high number of TB cases in Jember Regency and most of the area is in the form of agricultural fields and plantations that have a suitable humidity and temperature for the development of STH. The purpose of this study was to determine the relationship of personal hygiene risk factors with the risk of STH co-infection in TB patients in the work area of the Jenggawah Health Center in Jember Regency. This study used an observational analytic design with a cross sectional method and was conducted from September to December 2019. The research was conducted at the TB Polyclinic in Jenggawah Health Center in Jember Regency with a total sample of 26 respondents who were given a personal hygiene questionnaire. Stool examination was conducted at the Laboratory of Parasitology FK UNEJ using sedimentation and flotation methods. The results showed the incidence of STH co-infections was 15.3%, good personal hygiene was 57.7%, and bad personal hygiene was 42.3%. Fisher exact test results showed that there was no significant relationship between personal hygiene risk factors and the risk of the occurrence of STH co-infection in TB patients in the working area of the Jenggawah Health Center in Jember Regency (p = 1,000).

Abstract

Streptococcus pneumoniae is one of the bacterial pathogens that cause pneumonia. Pneumonia is the biggest cause of infant mortality in Indonesia around 23%. The main therapy pneumonia is antibiotics, but in some cases combined with ascorbic acid or N-acetylcysteine, which serves as a complementary therapy. The purpose of this study was to determine the effect of adding ascorbic acid or N-acetylcysteine ​​on antibiotics towards the growth of S. pneumoniae in vitro. The method used in this research is the method of germ-disc diffusion susceptibility test with S. pneumoniae growth inhibition is indicated by the formation of inhibition zone. Positive controls used clindamycin and erythromycin. The average diameter of inhibition zone on the negative control, positive control, and treatment of 1 to 5 on the addition of clindamycin with ascorbic acid are respectively 5; 24.12; 24.62; 26.08; 27.58; 28.74; and 29.76 mm. The data has a strong correlation to the Pearson test (R=+0,910). On a logarithmic regression analysis found minimal concentration of ascorbic acid can inhibit is 1.767 mg/ml. While the addition of erythromycin with N-acetylcysteine ​​are respectively 28.02; 25.62; 23.46; 22.42; and 21.68 mm. Pearson correlation test results of these data are the opposite relationship between the diameter of inhibition zone and the concentration of N-acetylcysteine ​​with a very strong correlation coefficient. Logarithmic regression of the minimum concentration of N-acetylcysteine ​​which may decrease the antibacterial activity of erythromycin inhibit the growth of Sreptococcus pneumoniae amounted 1,66mg/ml. It is concluded that ascorbic acid increases the activity of clindamycin in inhibiting the growth of S. pneumoniae in vitro and N-acetylcysteine ​​may decrease the antibacterial activity of erythromycin in inhibiting the growth of S. pneumoniae in vitro. Keywords: S. Pneumoniae, ascorbic acid, N-asetilsitein, inhibition zone
