Abstract

Due to their high mortality and morbidity rates, E. coli infections are a serious issue. Antimicrobial Resistance (AMR) is a result of this indiscriminate antibiotic use. One approach to address this issue is to utilize natural antimicrobials such as Sumbawa white honey. Sumbawa white honey contains antibacterial components like glucose and fructose (80%), water (17%), polyphenols, and hydrogen peroxide. This study aimed to analyze the antibacterial activity of white honey from Sumbawa against E. coli ATCC 25922. The research method employed was a laboratory experiment using a post test only control group design. Antibacterial testing was conducted using disc diffusion at concentrations of 25%, 75%, and 100%, with chloramphenicol as positive control and DMSO as negative control, and honey processing involved dilution. Antibacterial tests were repeated five times  and antibacterial activity was observed based on the diameter of inhibition zones around the disc. The outcomes showed that there was a restraint zone at 100 percent grouping of honey, to be specific 0.90 mm, while at 25% and 75% fixations there were no hindrance zones. According to the findings of this study, white honey from Sumbawa has a low antibacterial activity (0.90 mm), but this activity is ineffective against E. coli ATCC 25922. Further identification of the chemical components in Sumbawa white honey that are primarily responsible its antibacterial effect.

Abstract

A health problem associated with increasing antibiotic resistance, the silent pandemic kills 700,000 people a year, mostly in Asia and Africa. In the case of probiotic or lactic acid bacteria, antibiotic resistance can enhance nutrient absorption in the host and prevent the colonization of pathogenic bacteria. To address this, the WHO has suggested using the One Health Tricycle strategy, which entails monitoring people, the environment, and animals. One facet of this investigation is animals, specifically chickens. This study aims to identify the antibiotic resistance and profile of cefotaxime-resistant lactic acid bacteria (LAB) from broiler chicken cecum. Isolating LAB from the chicken's cecum is one of the techniques employed. After calculating the prevalence of resistant bacteria, the bacteria were characterized as macroscopic, microscopic, and biochemically. Testing the antibiotics against LAB was the next stage. According to the study's findings, the bacterial colonies were tiny to medium-sized, white, spherical, and convex, with complete margins. Gram-positive bacilli were identified by Gram staining. The findings of the biochemical tests were negative for oxidative and catalase, positive for glucose, and negative for other biochemical tests. According to antibiotic sensitivity testing, LAB was 90.9% resistant to Vancomycin, 63.63% to Chloramphenicol, and 100% to Erythromycin, Aztreonam, and Ceftriaxone. According to these findings, LAB in the chicken caecum has become resistant to several antibiotics. To give a better picture of the balance between pathogenic and helpful bacteria in the chicken cecum, more LAB testing against pathogenic bacteria is required.

Abstract

The subtherapeutic use of antibiotics as Antimicrobial Growth Promoters (AGPs) in broilers has accelerated Antimicrobial Drug Resistance (AMR) in gut microbiota, posing a global threat. This study aimed to analyze the population, morphology, catalase test results, and antibiotic sensitivity of erythromycin and vancomycin to cefotaxime-resistant Gram-positive bacteria in the caecum of broilers from Mataram City slaughterhouses. Using exploratory descriptive method, five caecum samples were analyzed by Total Plate Count (TPC) on Man Rogosa Sharpe Agar (MRSA) media with and without cefotaxime, and incubated on Mannitol Salt Agar (MSA). Results revealed uniform bacterial morphology on MRSA (small, round, convex, entire edge, white, Gram-positive colonies) but varied morphologies on MSA. Catalase tests were negative on MRSA but mixed on MSA. Resistance to erythromycin and vancomycin was 80% on MRSA, while on MSA, erythromycin resistance reached 62.5% with variable vancomycin inhibition zones. The prevalence of cefotaxime-resistant bacteria was 5.24%. This study highlights diverse morphological, catalase, and antibiotic sensitivity profiles in cefotaxime-resistant bacteria, particularly on MSA. These findings underscore the need for stricter antibiotic use regulations and further research to mitigate AMR spread in poultry production.

Abstract

Bacterial infections caused by pathogenic microorganisms remain a serious global health issue, exacerbated by the increasing incidence of antimicrobial resistance. Although synthetic antibacterial agents are effective, concerns have arisen regarding their long-term toxicity, bioaccumulation, and environmental impact. Consequently, the exploration of natural, safe, and eco-friendly antibacterial sources has gained significant attention. Tropical fruit peels, which are abundant agro-industrial by-products, contain diverse bioactive compounds such as flavonoids, tannins, saponins, and alkaloids that exhibit strong antibacterial potential. This literature review systematically evaluates the potential of tropical fruit peel extracts as active ingredients in antibacterial product formulations. Using a systematic review method, articles were collected from databases such as PubMed and Google Scholar, focusing on studies published between 2015–2025 that assessed the antibacterial activity of ethanol extracts from tropical fruit peels against bacteria including Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Streptococcus mutans, and Klebsiella pneumoniae. The findings indicate that peels of pineapple (Ananas comosus), banana (Musa spp.), mango (Mangifera indica), papaya (Carica papaya), pomelo (Citrus maxima), mangosteen (Garcinia mangostana), and durian (Durio zibethinus) show significant antibacterial activity. These extracts have been successfully formulated into antiseptic soaps, hand sanitizers, nanoemulgels, and herbal mouthwashes, offering effective and sustainable alternatives to synthetic antibacterial agents.

Abstract

Songgak is a concoction of the Sasak tribe of Lombok in West Nusa Tenggara. It consists of coffee mixed with groundwood, cloves, black pepper, coriander, and nutmeg. The original recipe involves roasting the spices before mixing them with coffee, namely using a frying pan over a stove. The roasting process is carried out without controlling the temperature and roasting time, so the roasted ingredients need to be standardized(Dewi et  al., 2021). GCMS is a tool used to analyze compounds in samples using chemical separation methods, mainly chromatography. The compounds in the mixture are separated in a chromatographic column. The separation mechanism between several compounds occurs due to differences in the solubility values of each in the moving solvent and differences in the absorption of each of the competing compounds into the stationary phase (Gross, 2017). In this research, variations will be carried out on spices, namely T1 original treatment of roasting spices over fire for 8 minutes, T2 drying spices in sunlight, T3 oven for 5 minutes, T5 oven for 5 minutes, T4 oven for 15 minutes and T5 oven for 15 minutes. In the T4 treatment, namely oven for 10 minutes, the results of the analysis of the substance content with the most types, namely 20 types, were obtained. The active anti-microbial compound found in all treatments was Hexadecanoic acid, 2-hydroxy-1-(h)(C19 H38 O4) BM:330, which helps inhibit the growth of cancer cells. (National Library Medicine, n.d.). Octadecanoic acid (CAS) Stear (C18 H34 O2) BM:282 Anti-inflammatory, Antiandrogenic Cancer prevention, Hypocholesterolemia Dermatigenic, 5-Alpha reductase inhibitor, Anemiagenic, Insecticide (Natarajan et al., 2019) and Tetradecanoic acid (CAS) Myris (C14 H28 O2) BM:228 as anti-inflammatory and anti-nociceptive.

Abstract

Klebsiella pneumoniae is an opportunistic bacterium often associated with antibiotic resistance, necessitating the investigation of natural antibacterial alternatives. Honey is recognized for its bioactive ingredients that possess antibacterial properties. This research sought to assess the antibacterial efficacy of Sumbawa forest honey (Apis dorsata) against K. pneumoniae ATCC BA1705 by inhibition zone test. A laboratory experiment was performed using the well diffusion technique. K. pneumoniae suspensions (McFarland 0.5) were injected onto Mueller Hinton Agar. Wells (Ø 6 mm) were filled with 100 µL of honey at concentrations of 25%, 50%, 75%, and 100%. Tetracycline (1 µg/µL) acted as the positive control, while distilled water functioned as the negative control. Plates were incubated at 35±2°C for a duration of 18 to 24 hours. Inhibition zones were quantified using a caliper, and each experiment was conducted in sextuplicate. Data were expressed as mean ± standard deviation. No inhibitory zones were found at 25% and 50% concentrations (0 mm). Antibacterial activity was seen at 75% concentration, yielding a mean diameter of 10.33±SD mm, and raised to 100% concentration, resulting in a mean diameter of 11.33±SD mm. Tetracycline generated a 26 mm inhibitory zone, while distilled water exhibited none (0 mm). The conclusion is Sumbawa forest honey exhibits concentration-dependent antibacterial activity against K. pneumoniae, with moderate inhibition at concentrations ≥75%. Although less effective than tetracycline, these findings support the potential role of honey as a complementary antibacterial agent.
