Abstract

Syphilis, a common sexually transmitted disease, is caused by Treponema pallidum subsp. pallidum. Owing to the chameleonic behavior of syphilis, ocular involvement still presents a therapeutic problem. Direct detection of Treponema pallidum in the vitreous offers a potential diagnostic method because serodiagnosis has considerable limitations. The worldwide identification of T. pallidum substypes has occurred since the advent of molecular typing approaches. The purpose of this article is to provide more information on the development of a molecular approach for Treponema pallidum detection. A body of literature was gathered using automated database searches in Google Scholar, PubMed, and ScienceDirect. Although prior studies have focused on other genes, such as polA, 16S RNA, and the whole genome, there are still some that use the study of the arp and T. pallidum repeat (tpr) genes to subtype. Whole blood, vaginal ulcers, skin biopsies, and other samples can be used in molecular methods. Comparing quantitative reverse trascription-polymerase chain reaction (qRT-PCR) to traditional methods, such as reverse transcription-polymerase chain reaction (RT-PCR), enzyme-linked immunosorbent assay (ELISA), indirect fluorescent antibody (IFA) assay, and virus isolation, qRT-PCR has the advantage of being faster and more sensitive. Quick molecular methods, particularly polymerase chain reaction (PCR) results, will enable early detection of primary, secondary, and latent syphilis, which will lead to prompt treatment and prevention of disease progression as well as a reduction in the amount of time that the patient's sexual partners are exposed to the illness.

Abstract

Single black garlic (SBG) is a product of processing garlic (Allium sativum L.) by heating it for several days. SBG has antibacterial activity due to the presence of organosulfur, phenolic and flavonoid compounds. This research aims to determine the antibacterial potential of SBG extract on Staphylococcus aureus and determine its chemical compound content based on Liquid Chromatography-Mass Spectrometer (LC-MS) analysis. The extract was obtained from the maceration method combined with a magnetic stirrer using 0, 30, 60 and 90% ethanol solvent. The antibacterial test used the disc diffusion method with a positive control of ciprofloxacin and a negative control of distilled water. LC-MS analysis of SBG extract with the best antibacterial activity. The results of the antibacterial activity test showed that the SBG extract had antibacterial activity based on the presence of an inhibition zone. The largest zone of inhibition in the 90% ethanol solvent SBG extract was 27.71 mm, and the positive control was 22.58 mm. The SBG extract with the most optimal antibacterial activity was analyzed using LC-MS to produce 109 compounds which were divided into 15 different compound groups, some of which were allicin (5.900%) which was the compound with the most composition and innulotetraose (0.065%) which was the compound with the smallest composition in the SBG extract. Data from the antibacterial test results were processed using the IBM statistical program SPSS 25, a One-way ANOVA test, which aims to determine the effect of antibacterial activity on Staphylococcus aureus bacteria, and data on the chemical compound content of the SBG extract were analyzed descriptively. SBG extract has the potential as an antibacterial which is classified as very strong in-vitro, so further in-vivo research is needed to apply the extract as an economical product that can treat skin infections and there are several compounds that dominate SBG extract with the highest antibacterial activity, such as organosulfur compounds, amino acids, flavonoids and phenolics based on LC-MS analysis.

Abstract

Sambal is often found in various menu variants served in the Indonesian food industry; this is a supporting factor for creating bottled chili sauce. In this research, fermented black garlic chili sauce was made with black garlic as raw material to provide added value in the form of antibacterial and antioxidant compounds, as well as giving a novelty value to the product as well as a differentiator in the elements of color, aroma, consistency, and taste of the product. The final product consumers receive is compared to "Cahyo" garlic chili sauce produced by PT. Deltasari Indah Restaurant. Sambal contains oil/fat, which is quickly rancid, thus affecting the element of consumer acceptance. Therefore, it is necessary to predict the shelf life of bottled chili products. This research aims to predict the shelf life of the black garlic chili sauce and “Cahyo” garlic chili sauce products in bottles produced by PT. Deltasari Indah Restaurant with the ASLT method, the Arrhenius model approach; Knowing the difference in the shelf life of bottled chili products stored at different temperature conditions; and determining the proper temperature and storage conditions to get the maximum shelf life for packaged chili products. This study uses the Accelerated Shelf-Life Testing method with the Arrhenius model. Based on the pH value parameter, the shelf life of black garlic chili sauce was 33 days, and “Cahyo” garlic chili sauce was 45 days. These two results are the results of the shelf life obtained from calculations at 20?C and 25?C then the average value is taken.

Abstract

Staphylococcus aureus (S. aureus) is the most common pathogen in humans that causes various infections. Variations in infections due to S. aureus are related to the presence of virulence factors, one of which is Toxic Shock Syndrome Toxin-1 (TSST-1) which is the main cause of Toxic Shock Syndrome (TSS). This study aimed to explore the genetic pattern of the tsst-1 genes among MSSA and MRSA from clinical isolates of patients at Dr. Soetomo Academic Hospital, Surabaya-Indonesia. PCR examination was performed on 106 clinical samples of S. aureus isolates to determine the presence of the tsst-1 genes; subsequently, phylogenetic analysis was performed. The positive tsst-1 genes were found in 3 (5.7%) MSSA isolates and 2 (3.8%) MRSA isolates from 106 samples, of which were divided into 53 MSSA isolates and 53 MRSA isolates. No significant difference was noticed between the tsst-1 genes on both the MSSA and MRSA bacteria (p = 0.648). The positive tsst-1 genes were found in 1 (4.5%) of pus specimens and 2 (16.7%) of blood specimens from MSSA isolates. However, the positive tsst-1 genes were found in neither sputum nor urine specimens. The genes were found in 2 (16.7%) of blood specimens from MRSA isolates. Based on the phylogenetic tree, Indonesian tsst-1 isolates belonged to the same clade as Japan, Iran, Iraq, India, Egypt and the United Kingdom isolates. The prevalence of tsst-1 genes of both MSSA and MRSA from clinical isolates in Dr. Soetomo Academic Hospital Surabaya are 5.7% and 3.8%, respectively. The tsst-1 genes of Surabaya-Indonesia, Japan, Iran, Iraq, India, Egypt and the United Kingdom belonged to the same clade.

Abstract

This study aimed to explore the phylogenetic pattern of Extended-spectrum β-lactamase-producing Escherichia coli in the gut flora of neonatal into groups A, B1, B2, D and tracing the presence of spreading among the age group of neonatal. Multiplex PCR was conducted to classify the phylogenetic group of ESBL producing E. coli into groups of commensals (A, B1) and pathogen (B2, D). The spread of bacterial agents among the host (neonatal) was conducted by the RAPD-PCR method with two random primers. Among 34 bacterial isolates were identified among early neonatal group A (22,2%), B1 (11,1%), B2 (22,2%) D (33,3%) and postneonatal groups A (8%), B1 (4%), B2 (36%) D (40%). It was not a statistically significant difference (p=0.388). The dominance of pathogenic groups B2 and D as many as 70,6%. From 34 samples was found 34 types of RAPD indicated there were not any bacterial spread among neonatal. The ESBL producing E. coli among early neonatal and postneonatal were dominated by the pathogenic group of B2 and D (total=70,6%), but they were not statistically significant. There was not any spreading of bacterial agents among individual gut flora of neonatal.
