Abstract

Role of Pili Protein 11 kDa of Streptococcus pneumoniae as Hemagglutinin and Adhesin Protein Streptococcus pneumoniae has pili which play roles in adhesion, colonization of nasopharyngeal epithelial cells, and phagocytic inhibition of immune cells. This study aimed to determine the characteristics of the 11 kDa pili protein as hemagglutinin and adhesin, as well as their immune responses. The 11 kDa pili protein from S. pneumoniae was isolated by SDS-PAGE, purified by electroelution and dialysis. Hemagglutination and adhesion tests were carried out on the protein, and western blotting of the polyclonal antibody immune responses were evaluated. Hemagglutination test showed that the 11 kDa pili protein played a role in the hemagglutination process up to 2-time dilution. Adhesion test showed there was a correlation between the dose of the protein and the bacteria attached to the epithelial cells. The Pearson correlation test showed a P value of 0.010 and a correlation coefficient of R = -90.919. Quadratic regression test produced R2 = 0.974. Western blotting test showed that 11 kDa pili protein polyclonal antibodies recognized 67 kDa and 11 kDa pili proteins. The study concluded that the 11 kDa S. pneumoniae pili protein acted as hemagglutinin and adhesin, and the polyclonal antibody protein responded to 67 pDa and 11 kDa BM pili proteins.Keywords: adhesin, hemagglutinin, pili, protein 11 kDa, Streptococcus pneumoniae ABSTRAKStreptococcus pneumoniae memiliki pili yang berperan dalam adhesi, kolonisasi sel epitel nasofaring, serta sebagai inhibitor fagositosis sel imun.

Abstract

Klebsiella pneumoniae as one of the most common cause of VAP is also the second most common cause of community- and hospital-acquired gram negative bloodstream infection. The process of infection caused by direct contact with infectious agents begins with the host cell adhesion process either by pili or by afimbria adhesin (AFA). There were no reported researches on the hemagglutinin pili protein of K.pneumoniae as adhesion factors.This study was conducted in order to determine the hemagglutinin pili protein of K.pneumoniae, polyclonal antibody produced from pili protein immunization, and its ability to inhibit K.pneumoniae adhesion in mice enterocytes. Adhesion inhibition test used HA antibody with the implementation of dose dilutions of 1/100, 1/200, 1/400, 1/800, 1/1600, 1/3200 and 0 (control). While immunocytochemistry test used HA pili protein with the implementation of dose dilutions of 1/10000, 1/20000, 1/40000, 1/80000, 1/160000, 1/320000 and 0 (control). Hemagglutinin pili protein found in K.pneumoniae had MW 12.8 kDa. Pearson correlation analysis of adhesion test showed there were significant correlation between antibody dilution titer with bacterial adhesion (p = 0.032, R = -0.797). Furthermore, Anova analysis of IT showed that there were significant differences between the various dilution titer with antigen-antibody reaction (p=0.000). Antibody of hemagglutinin pili protein with MW 12.8 kDa of K.pneumoniae can inhibit the adhesion of K.pneumoniae to the enterocytes of mice.

Abstract

Pseudomonas aeruginosa merupakan salah satu bakteri penyebab infeksi yang sulit diobati dengan terapi obat tunggal karena tingkat keberhasilan yang rendah serta kecenderungan menjadi resisten selama pemberian obat tunggal. Salah satu antibiotik yang digunakan adalah ciprofloxacin. Untuk meningkatkan sensitivitas P. aeruginosa terhadap ciprofloxacin, kombinasi N-asetilsistein atau vitamin C mungkin diperlukan. Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi antara N- asetilsistein dan ciprofloxacin serta antara vitamin C dan ciprofloxacin terhadap pertumbuhan P. aeruginosa. Penelitian ini menggunakan uji difusi cakram yang berisi kombinasi konsentrasi ciprofloxacin konstan 1mg/ml dengan N-asetilsistein dalam berbagai konsentrasi 1,25mg/ml, 2,5mg/ml, 5mg/ml, 10mg/ml, dan 20mg/ml dan vitamin C dengan 2,5 mg/ml; 5 mg/ml; 10 mg/ml; 20 mg/ml; dan konsentrasi 40 mg/ml. Dalam kombinasi antara N-asetilsistein dan ciprofloxacin, peningkatan sensitivitas P. aeruginosa terjadi pada konsentrasi 10ml/mg pada kombinasi obat, dan dalam kombinasi antara vitamin C dan ciprofloxacin, peningkatan sensitivitas P. aeruginosa terjadi pada konsentrasi 2, 5 ml/mg pada kombinasi obat di atas kontrol positif. Regresi logaritmik mengungkapkan konsentrasi minimal N- asetilsistein dan vitamin C masing-masing adalah 9,593 mg/ml dan 1,9 mg/ml dapat meningkatkan sensitivitas P. aeruginosa pada ciprofloxacin. Dapat disimpulkan bahwa N-asetilsistein dan vitamin C meningkatkan aktivitas ciprofloxacin untuk menghambat pertumbuhan P. aeruginosa in vitro.

Abstract

Tuberculosis (TB) and intestinal worms are infectious diseases with a large number of sufferers in Indonesia. The high prevalence of intestinal worms in Indonesia allows the occurrence of STH coinfection in pulmonary TB patients which causes anti M. tuberculosis immunity to decrease so that the response to tuberculosis treatment is not optimal. One of the risk factors of STH infection is personal hygiene. The purpose of this study was to analyze the relationship between individual hygiene and the incidence of STH coinfection in TB patients in Tempurejo Sub-District, Jember District. This type of research is observational research with cross sectional analytic design. The population used was TB patients in Tempurejo Sub-District in the period September - October 2019. The data used in this study were primary data in the form of interviews and results of stool examination. Stool examination is carried out using the sedimentation and floatation methods. Data analysis was performed using Fisher's exact test. The results of this study indicate that the incidence of STH co-infection in TB patients in Tempurejo Subdistrict is 9.67% and is caused by two STH species, A. lumbricoides (66.7%) and Hookworm (33.3%). Respondents' personal hygiene consisted of good hygiene (64.5%) and bad hygiene (35.5%), where 66.7% of cases of STH coinfection occurred in respondents with poor personal hygiene. Fisher's test results showed that there was no significant relationship between personal hygiene with the incidence of STH coinfection in TB patients in Tempurejo Sub-District, Jember District (p-value of 0.281).

Abstract

Globally, helminthiasis is one of the infectious diseases that are often associated with the incidence of tuberculosis. Helminth co-infection modulates the immune system of TB patients by reducing Th-1 response that functions as protector against Mycobacterium tuberculosis. This condition disrupts the process of eliminating bacteria so that its development becomes more progressive. The impact is the activation of latent TB and the success of TB treatment. A Soil-transmitted Helminth (STH) is a group of intestinal worms that often infect humans. Previous studies prove that environmental sanitation and personal hygiene are risk factors associated with STH infection. The study to determine the relationship of environmental sanitation and personal hygiene with the incidence of STH co-infection in TB patients at Puskesmas Puger, Jember in September until December 2019. This study uses a cross-sectional design. The sampling technique uses total sampling. A total of 32 TB patients met the criteria as study sample. The data analysis uses Fisher Test. Results showed the prevalence of STH co-infection was relatively low (18.8%); most of the respondents had good environmental sanitation and personal hygiene conditions. Bivariate analysis showed p-value (0,476) for environmental sanitation and p-value (1,000) for personal hygiene. This study concludes that there is no correlation between environmental sanitation, personal hygiene, and STH co-infection in TB patients at Public health center in Puger.

Abstract

BackgroundStreptococcus pneumoniae causes pneumococcal disease, which is responsible for millions of deaths worldwide. Various pneumococcal vaccine candidates have been developed to prevent S. pneumoniae infection, one of which is an epitope-based vaccine. This study aimed to prove that intranasal immunization with each of the five S. pneumoniae RrgB epitopes can induce a mucosal immune response by increasing the β-defensin-2 concentration through upregulation of interleukin (IL)-22 expression. MethodsAn experimental laboratory study was conducted using 28 male Wistar rats aged 3-4 months, that were randomly divided into 7 groups containing four rats each. Group 1 was given 40 mL of phosphate-buffered saline (PBS) only (control group). Group 2 was the adjuvant group that received 40 mL PBS containing 2 ìg cholera toxin B (CTB), and groups 3-7 were immunized with 40 mL PBS containing a combination of adjuvant and one of the five different S. pneumoniae RrgB epitopes. The concentrations of IL-22 and β-defensin-2 from nasal rinse examination were measured by means of ELISA. The Kruskal-Wallis test, followed by the Mann-Whitney post-hoc test were used for statistical analysis. ResultsRats immunized with the adjuvant-epitope combination had significantly higher β-defensin-2 and IL-22 levels than the control group (p=0.030; p=0.018, respectively), according to the Kruskal-Wallis test. And the Mann-Whitney statistical test, showed there was a significant increase in β-defensin-2 and IL-22 levels. ConclusionsIntranasal immunization with epitope 1 of the S. pneumoniae RrgB can increase β-defensin-2 expression significantly and has a greater potential to be developed into a pneumococcal vaccine.

Abstract

Nearly 35 million cases and one million deaths over the nine months of the COVID-19 pandemic have been reported worldwide. Africa and some countries with endemic parasitic infections had a low incidence of COVID-19. By contrast, the United States and several European countries, having a non-endemicity of parasitic infections, recorded a high incidence of COVID-19. Some parasites have an immunomodulatory mechanism that can induce an immune tolerance state in the infected persons by balancing pro-inflammatory and anti-inflammatory responses. Emerging reports also stated that COVID-19 and helminth co-infections may have more hidden outcomes than predictable ones. Hence, the aim of this literature review is to show and identify that an increase in the number of regulatory immune cells due to the immunomodulatory role of a pre-existing parasitic infection could reduce the risk of COVID-19. This study explored the existing literature to determine the role of parasitic infections in modulating the immune response and possibly reduce the risk of COVID-19 infection in endemic countries. The mechanism of immunomodulation by parasites is the increased numbers of Treg cells, M2 macrophages, eosinophils, the Th2 cytokines IL-4 and IL-5, and the pro-inflammatory downregulation of IFN λ, TNF α, and IL-6, which play an essential role in inducing cytokine storms in COVID-19 infection. This condition will probably occur in an individual with parasitic infection in a community with limited facilities and infrastructure to treat parasitic infections, particularly in developing countries. To conclude, in endemic areas, the immunomodulatory effect of parasitic infection to reduce the risk of COVID-19 cases/deaths is a possibility if the host is immunocompetent. Herein, the current knowledge on the immunomodulatory role of COVID-19 and helminth co-infections will be discussed.
