Abstract

In early life, Bifidobacteria are reported as dominant bacteria in the human digestive tract. Bifidobacterium is potential as a probiotic. The probiotic property of Bifidobacterium is strain-specific. This study aimed to identify the Bifidobacterium (isolated from less than one-month-old healthy infant stool that potentially used as probiotic) based on the 16S rRNA gene and determining their similarities among Bifidobacteria. The probiotic-potentially Bifidobacterium was re-characterized by performing a Gram’s staining and catalase test. The DNA extraction process was followed by the 16S rRNA amplification using 27F-1492R primers. Sequence similarity was checked by using the BLAST program in the GenBank. The phylogenetic tree was constructed by using a neighbor-joining (NJ) method within the MEGA version 7.0 package. The 16S rRNA gene was presented at 1,500 bp length. Bifidobacterium strains have a 91.14-94.26 % sequence similarity to B. longum subsp. longum strain CCUG30698 which is considered as insufficient for species and genus identifications. However, those isolates could be assigned in a phylogenetic position. This present study suggested the B. longum as the dominant strain of Bifidobacterium in the gut of early-life infants which has potential as a probiotic and is considered as an ideal probiotic for human consumption. This study is useful as basic information for other related research, as well as its application in industrial or community service fields.

Abstract

Dengue prevention efforts are limited to the control strategies of its vector and the management of breeding sites. New alternatives for dengue vector control that are sustainable and more environmentally friendly are needed to complement the government's current efforts. Research on Wolbachia-infected Aedes aegypti Linnaeus mosquitoes as an alternative biocontrol strategy has been performed in Yogyakarta City. However, one of the concerns of the community members and stakeholders about this technology is the safety aspect regarding the transmission of Wolbachia to other species and the possibility that humans will contract Wolbachia. This study aimed to address these concerns, namely to find out whether horizontal transmission of Wolbachia occurred from A. aegypti that were released to other species and whether residents living in the released areas were infected with Wolbachia. The research was conducted in Dusun Nogotirto and Dusun Kronggahan (Sleman Regency), as well as in Dusun Jomblangan and Dusun Singosaren (Bantul Regency), Yogyakarta Special Province. Wolbachia qPCR screening using the target gene WD0513 was performed on 922 Culex quinquefasciatus Say and 331 Aedes albopictus (Skuse). ELISA test was carried out on 190 pairs of plasma samples, namely the sample before the Wolbachia frequency was established (still <80%) and the sample after it was established (>80%). The results showed no evidence of Wolbachia transfer from Wolbachia-infected A. aegypti to other mosquito species coexisting in the same habitat or to humans. This study corroborates the safety evidence of Wolbachia-infected A. aegypti technology as an alternative to control dengue virus transmission

Abstract

Breast cancer is the most common type of cancer worldwide. One of the most widely used chemotherapeutic agents in the treatment of breast cancer is doxorubicin. However, doxorubicin has been reported to cause side effects. Suruhan (Peperomia pellucida) contains bioactive compounds that might protect against breast cancer cells. This study aims to analyze the bioactive compound activity of Suruhan leaves in triple-negative breast cancer in silico. The study was conducted by reviewing published literature on bioactive compounds in Suruhan leaves, predicting the protein target, analyzing the gene expression in triple-negative breast cancer (TNBC) patients, analyzing the protein interactions, and examining patient survival. There are five common bioactive compounds in Suruhan leaves, including peperomin A; 6,8-dihydroxy kaempferol 3,6,7,4'-tetramethyl ether 8-neohesperidoside; dillapiole; carotol; and pellucidin A. AURKA is a target protein for bioactive compounds that are also overexpressed in TNBC patients. AURKA has strong interactions with many proteins, including TPX2, NEDD9, CCNB2, CDC20, PLK1, BIRC5, INCENP, TACC3, TP53, and MYCN. The AURKA has emerged as a promising target for TNBC therapy.

Abstract

Tuberculosis is a significant global infectious disease cause of mortality, with 25% of the world's population caused by Mycobacterium tuberculosis (Mtb). The highest case recorded was 821,200 cases in 2023 over one decade. Drug resistance significantly impacts tuberculosis treatment and has been observed since the first drug discovery, streptomycin. In Indonesia, drug-resistant tuberculosis (DR-TB) is a significant public health issue, with an estimated 24,666 cases recorded in 2022. A comparative literature search was conducted using various articles, including research studies, guidelines, narrative reviews, reports, and meta-analyses, with the inclusion criteria for reference sources including ten years of published articles. Drug resistance in TB can reduce treatment success rate and increase therapy duration. In the result, several general mechanisms proposed for drug resistance in Mtb include efflux pump, enzyme inactivation, permeability barrier, mutations in drug-target genes, and epigenetics. Currently, TB treatment in Indonesia involves combination therapy using three or more types of drugs, such as rifampicin and isoniazid. The International Standard for TB Care (ISTC) serves as the basis for TB diagnosis in Indonesia, which involves a combination of clinical and laboratory tests. Early diagnosis and universal access to the Drug Susceptibility Test (DST) are crucial for TB resistance. In Indonesia, several diagnostic methods, such as sequencing, PCR testing, Gene Xpert, and culture, can be used to identify TB resistance. Understanding the mechanisms of drug resistance and developing effective diagnosis strategies for TB resistance is crucial for managing global infection.

Abstract

Most of the microbes inhabiting the oral cavities are harmless but can cause disturbance and discomfort if the microbial population increases significantly. One of the oral disorders that is often experienced by children, is dental caries. Dental caries is causedby various factors, including eating and brushing habits. The people of Central Kalimantan who live in the watershed use peat water in their daily activities, including for gargling and brushing their teeth. The acidic characteristics of peat water and the high content of organic substances trigger the development of microbes that cause dental caries.This study used dental caries swab samples of patients who rinsed their mouths with peat water. Bacteria were identified molecularly with 16SrRNA markers with primers 63F and 1387R. The similarity of nucleotide sequences was analyzed with BLAST on GeneBank. A phylogenetic tree was built with Maximum Likelihood. Both isolates have a fairly high level of similarity to Klebsiella pneumoniae, namely 91% and 93%. Both isolates are in the same clade, Klebsiella spp., and are close to various commonly found bacteria in the oral cavity, such as Streptococcus mutans and Lactobacillus salivarius.

Abstract

Scientists are performing various measurements to overcome the COVID-19 pandemic. The genomic mutations of SARS-CoV-2 can change their pathogenicity, infectivity, transmission, and antigenicity. This present study aimed to know a) the genetic variation of structural and functional genes of SARS-CoV-2 circulating in Banyumas and b) the potential of the Cilacap’s Harbour as a human mobility portal on the genetic variations of SARS-CoV-2 circulating in Banyumas, Central Java (Indonesia). Genomic sequence of SARS-CoV-2 isolates were taken from the Global Initiative on Sharing All Influenza Data (GISAID) and the National Center for Biotechnology Information (NCBI) online platforms. A gene cut was carried out from Wuhan reference isolate, fifteen isolates from Banyumas, and two isolates from Cilacap (Central Java) using Unipro UGENE v. 33.0 software, considering the annotation of the Wuhan-1 isolate. Genetic variations were detected among SARS-CoV-2 isolates circulating in Banyumas. The structural protein (envelope, membrane, nucleocapsid) encoding gene and the RdRp gene were highly conserved to Wuhan reference genome (Wuhan-Hu-1). Meanwhile, the ORF and the spike-encoding genes were less identical to the Wuhan reference genome. This study also proposed that human mobility from outside Central Java through Cilacap’s Harbour did not affect the genetic variation of SARS-CoV-2 isolates circulating in Banyumas (Central Java).

Abstract

Wolbachia are the most prevalent and successful endosymbiont in invertebrates and are categorized into 21 supergroups based on genetic phylogeny. The filamenting temperature-sensitive Z (FtsZ) protein is essential for bacterial cell division and is hypothesized to play a role in Wolbachia's control of host reproduction. However, despite FtsZ's importance, little is known about its diversity and function within Wolbachia. This study investigated the variability of the FtsZ-encoding gene among Wolbachia strains and their hosts. FtsZ gene sequences were retrieved from the National Center for Biotechnology Information database, and representative sequences were randomly selected from each host species and analyzed for phylogenetic relationships. A total of 1–10 sequences for each of the Wolbachia strains infecting the various hosts were included in the analysis. The ftsZ gene sequences ranged from 450 to 970 base pairs, with a consensus sequence of 520 base pairs. Phylogenetic analysis revealed substantial genetic divergence in the ftsZ gene among Wolbachia strains from different host species. In contrast, Wolbachia strains within the same host species exhibited a lower level of genetic variation, which indicates that the gene pool within populations is relatively homogeneous.

Abstract

Infectious diseases are still a global problem, for example, acute respiratory infections (SARI). Resistance in pneumonia involving Gram-negative bacterial infection reduces the effectiveness of antibiotic use and increases the length of hospital stay. This study examines the potential of antimicrobial compounds from basil plants against isolates of Gram-negative bacteria involved in pneumonia infection. This research is an experimental study through several stages: basil extraction, initial screening of bioactive compounds, isolation and identification of bacteria from sputum, and testing for antimicrobial activity of basil extracts. Sputum samples were collected from 43 pneumonia patients (male and female) involving Klebsiella pneumoniae, Acinetobacter baumannii, Enterobacter aerogenes, Pseudomonas aeruginosa, Serratia marcescens, Proteus mirabilis, and Escherichia coli. The inhibitory activity against pathogenic bacteria was directly proportional to the basil extract concentration. Initial screening for phytochemical compounds showed that the extracts of basil leaves and stems contained active compounds of tannins and flavonoids. The 25% concentration of basil extract was the minimum inhibitory concentration (MIC) against the test bacteria. The 100% basil extract concentration produced the largest inhibition zone i.e., 10.93 mm. The overall findings of this study provide baseline information for the possible use of the Ocimum basilicum extract in the treatment of pneumonia involving Gram-negative bacteria.

Abstract

Purpose: To discuss the current condition of food estate in Kalimantan Tengah, the environmental and social costs, and how to balance the competing interests. Results: Food security is a global concern. The food estates in Central Kalimantan represent a strategic initiative of the Indonesian government aimed at bolstering national food security through the establishment of extensive, integrated agricultural zones. However, they also come with significant environmental and social costs. Large-scale deforestation and habitat disruption associated with food estates can force wildlife closer to human populations and livestock. Excessive use of pesticides and fertilizers in food estates can contaminate water sources, impacting aquatic life and harming human health. The relationship is complex and often fraught with tension. Balancing these competing interests requires a multi-pronged approach. The policy should be applied in the open-participatory concept, where all parties involved are involved in formulating, implementing, and evaluating the policy. Thus, the policy becomes the fruit of collective thinking, and there is a sense of ownership of each party to the policy. Not only from the implementation side but also from the evaluation process. In food estates, the use of resources is tied to the emergence of clientelism practices, where social, economic, and political ties form a very hierarchical network in the implementation of food estates. The lack of alignment and sustainable planning in implementing the food estate has also led to failure in maintaining the desired power through the program. Conclusion: Sustainable public policies, community engagement, and a shift towards environmentally friendly agricultural practices are crucial for ensuring food security for the future without compromising public and environmental health.

Abstract

AbstractBifidobacteria have beneficial health effects for their hosts. However, they may acquire antibiotic-resistance genes. They may transfer antibiotic-resistance genes to pathogenic microbes found in the human intestine resulting in the emergence of antibiotic-resistant pathogens. This study aimed to predict their resistance to antibiotics by analyzing the whole genome sequence. The entire genome data of Bifidobacterium spp. were obtained from the National Center for Biotechnology Information (NCBI). This study included five Bifidobacterium strains of human origin, five strains of animal origin, and three strains isolated from the environment. The genomic sequences were analyzed using ResFinder and CARD web service. Antibiotic-resistance genes were detected in Bifidobacterium spp. from all sample sources. Bifidobacteria were potentially resistant to various antibiotics, such as tetracycline, rifamycin, chloramphenicol, macrolide, lincosamide, streptogramin, and mupirocin-like antibiotics. This study suggests the safety aspect consideration of applying Bifidobacterium spp. as a potential probiotic.AbstrakBifidobacteria memiliki efek kesehatan yang menguntungkan bagi inangnya.
