Abstract

Background: Caulerpa lentillifera is a species of green algae that has been cultivated widely in Indonesia for its nutritional contents and health benefit. This seaweed builds a strong association with bacterial community which play an important role in synthesizing various secondary metabolites including antibacterial activity. Aims:The research aim to explore the symbiotic relationship between C. lentillifera and its associated bacterial community, focusing on the potential of these bacteria to produce antibacterial metabolites.Methods:Bacterial cultivation was performed on three different media namely nutrient agar, plate count agar, and zobell marine agar. The obtained bacterial isolates were identified morphologically and subsequently were screened for their antibacterial activity based on perpendicular cross streak method against Staphylococcus aureus ATCC 25923, Streptococcus mutans FNCC 0405, Escherichia coli ATCC 25922, and Klebsiella pneumoniae ATCC 700603. Results: 20 out of 28 bacterial isolates inhibited against at least one of the bacterial targets. Bacterial isolate encoded as NAR9 showed as the most promising bacterial isolates with length inhibition of 19 mm against S. mutans FNCC 0405. Amplification of 16S rRNA gene fragment of the NAR9 bacterial isolate followed by Sanger sequencing showed that the isolate NAR9 has been phylogenetically related to Marinobacter hydrocarbonoclasticus. Conclusion: Overall, this research provides a preliminary result of the untapped potential of bacteria associated with C. lentillifera as the source of antibacterial activity.

Abstract

Highlights: • Eschericia colli was the most contaminant bacteria among food samples from Warmadewa Cafeterias • Further suggestions to increase the hygiene in food processing must be offered. Abstract : Foodborne diseases still remain a problem especially in public areas. This study aimed to identify pathogenic bacteria in foods sold at the cafeterias of Universitas Warmadewa, Denpasar, Indonesia. The presence of pathogenic bacteria in the food samples was identified using the brain heart infusion (BHI) agar for the growth of Escherichia coli and Streptococcus aureus, selenite for Shigella and Salmonella, and alkaline peptone for Vibrio cholerae, then bacterial culture was conducted to identify the species. The results showed that Escherichia coli were found in two food samples, kangkong and jinggo rice, with the colony counts of 50-118. Escherichia coli was the most commonly found contaminant in food samples from the Warmadewa Cafeterias. Further suggestions must be offered to increase hygiene in the food processing by advising the stalls' owners to serve good foods and conducting regular inspections to assess the food quality.

Abstract

Background: Pulmonary tuberculosis (TB) remains among the top ten leading causes of death globally. Sociodemographic factors, comorbidities, TB type, and history of contact with TB patients are established risk factors for TB incidence. Purpose: The objective of this study was to identify the characteristics of pulmonary TB patients at Wangaya Regional General Hospital in 2023. Methods: A total sampling approach was utilized. Inclusion criteria comprised patients aged 15 years or older diagnosed with pulmonary tuberculosis at Wangaya Regional General Hospital in 2023. Patients with damaged or unreadable medical records were excluded. Results: Among 133 TB patients, drug-sensitive tuberculosis (DS-TB) was identified in 117 patients (88%), while drug-resistant tuberculosis (DR-TB) was found in 16 patients (12%). The majority of DS-TB cases occurred in individuals of productive age (60.2%), male (66.9%), employed in the private sector (76.7%), with low educational attainment (96.6%), a history of contact with TB patients (37.6%), newly diagnosed cases (34.6%), and HIV as the most common comorbidity (14.3%). Among DR-TB cases, most patients were in the productive age group (81.3%), male (75%), private sector workers (75%), with low educational attainment (100%), a history of contact (43.8%), newly diagnosed cases (62.5%), and type 2 diabetes mellitus as the most common comorbidity (31.3%). Conclusion: In 2023, the majority of drug-sensitive and drug-resistant pulmonary TB cases at Wangaya Regional General Hospital occurred in productive-age patients, predominantly male, employed in the private sector, with low educational attainment, positive contact history, and classified as new cases.

Abstract

Infeksi dengue masih menjadi masalah kesehatan yang menguakitrkan baik pada masyarakat escara umum maupun wisatawan yang berlibur di Bali secara khusus. Mitra adalah pekerja peertamanan di kawasan hotel di Nusa Dua yang memiliki permasalahan berupa kurangnya pemahaman tentang penyakit demam dengue, identifikasi tempat perindukan nyamuk serta pemanfaatan tanaman pengusir nyamuk Kegiatan pengabdian ini dilaksanakan untuk meningkatkan pengetahuan dan keterampilan pekerja pertamanan hotel dalam pencegahan dengue melalui pendekatan edukasi berbasis lingkungan. Metode kegiatan meliputi penyuluhan interaktif, pelatihan budidaya tanaman pengusir nyamuk, serta pemberian bibit dan suplemen kesehatan. Evaluasi dilakukan melalui pre-test dan post-test. Hasil menunjukkan peningkatan pengetahuan dan kemampuan peserta dalam menerapkan pencegahan dengue secara praktis di area kerja. Kegiatan ini menyimpulkan bahwa edukasi terpadu dan budidaya tanaman pengusir nyamuk efektif dalam meningkatkan kesadaran mitra serta mendorong keberlanjutan upaya pengendalian dengue berbasis lingkungan.
