“…Besar kecilnya zona hambat yang terbentuk dipengaruhi oleh berbagai faktor: (1) konsentrasi zat, semakin tinggi konsentrasi zat antibakteri maka diameter zona hambat yang terbentuk semakin besar (Waluyo, 2007); (2) pengorganisasian dinding sel bakteri juga merupakan faktor penting yang dapat mempengaruhi tingkat efisiensi antibakteri. Bakteri gram negatif biasanya memiliki membran luar terorganisir dan lebih kompleks daripada bakteri gram positif, dan kehadiran membran luar yang tersusun atas lipopolisakarida yang padat membuat bakteri gram negatif lebih tahan terhadap desinfektan daripada bakteri gram positif (Wang et al, 2015).…”

Marine invertebrates are the most productive source of bioactive compounds. However, most of the compounds originally produced by the microorganisms living associated with the invertebrates. Barnacle is an invertebrate that has a unique interaction with bacteria. Escherichia coli and Bacillus cereus are the cause of the foodborne disease that causes of remarkedly losses in the food industry. The barnacle was collected from Panjang Island, Jepara. The bacterial isolates were obtained by serial dilution followed by isolation based on morphological characteristics. The antagonistic assay to E. coli dan B. cereus was utilized for screened the isolates. Then, the active isolates were cultured for the further test with the disc diffusion agar method of the supernatant followed by the extracts. The most active isolates were identified based on molecular method. A total of 14 isolates were obtained from the Balanus sp., which six of them have activity against the E. coli and B. cereus. The isolates TJ 5.4 and TJ 5.5 have the strongest activity the bacteria. Base on the analyses of the BLAST and phylogenetic tree the isolates showed 99% homology the Bacillus wiedmannii (TJ 5.4) and Lysinibacillus macroides (TJ 5.5). Invertebrata laut merupakan salah satu sumber bahan bioaktif yang paling produktif. Sebagian senyawa yang terdapat dalam biota laut, sejatinya diproduksi oleh mikroorganisme yang hidup berasosiasi dengan biota laut tersebut. Teritip merupakan salah satu hewan invertebrata yang memiliki berbagai interaksi unik dengan bakteri. Bakteri Escherichia coli dan Bacillus cereus merupakan dua dari beberapa bakteri patogen yang sering menjadi agen penyebab foodborne disease. Teritip dikoleksi dari Pulau Panjang, Jepara. Isolat bakteri diperoleh dengan metoda pengenceran bertingkat dan dilanjutkan isolasi berdasarkan karakteristik morfologis. Uji antagonis terhadap E. coli dan B. cereus digunakan untuk menskrining bioaktivitas isolat. Isolat yang aktif dikultur untuk uji lanjut yaitu supernatant dan dilanjutkan ekstraknya dengan metoda disc diffusion agar. Bakteri yang paling aktif diidentifikasi secara molekuler untuk mengetahui spesiesnya. Sebanyak 14 isolat bakteri diperoleh dari Balanus sp. dimana enam diantaranya memiliki aktivitas terhadap bakteri uji. Isolat TJ 5.4 dan TJ 5.5 memiliki aktivitas paling kuat terhadap E. coli dan B. cereus. Berdasarkan pengolahan sekuen dan analisis pohon filogenetik, dua isolat bakteri tersebut memiliki homologi 99% terhadap bakteri Bacillus wiedmannii (TJ 5.4) dan Lysinibacillus macroides (TJ 5.5).

Objectives: The purpose of our research was to examine the effects of Minocycline combined hyaluronic acid (HA)-mediated Ultrasound therapy of infected wound in wister rats .Methods: 40 female wister rats were made wound on the two side of the backbone, then infected in Staphylococcus aureus at the comic for three times. then ,they are divided into four groups: control group, minocycline combined HA alone, ultasound alone , minocycline combined HA-mediated ultasound group ,respective. After 3 times of treatments, the rats were killed and made into specimens.Assessments consisted of visual inspection in the change of the skin, scar formation pathological morphology by hematoxylin and eosin(HE) stain with optical microscopy,IL-1B assaying and TNF-a were performed. Result: Compared with control group, minocycline combined HA alone, ultasound alone, minocycline combined HA-mediated ultasound group all have effect for wound healing, there was a obvious improvement in all parameters over the duration of the experiment(P<0.05). Compared with the control group, minocycline combined HA-mediated ultasound group indicated less inflammation cells (P<0.001) and the reduce of and IL-1B and TNF-a (P<0.001) .Conclusion: Minocycline combined HA-mediated ultrasound can accelerate tissue regrowth ,which exert significant benefits in healing the wounds.

“…The antibacterial activity of curcumin is due to its action against the bacterial membrane [94]. Curcumin inhibited the growth of periodontopathic bacteria P. gingivalis, Prevotella intermedia, Fusobacterium nucleatum, Treponema denticola [95], foodborne bacteria Bacillus cereus and Escherichia coli [96], methicillin-resistant Staphylococcus aureus (MRSA) [97], Enterococcus faecalis, Bacillus subtilis, Streptococcus mutants, and Pseudomonas aeruginosa [94].…”

Worldwide Wound Healing - Innovation in Natural and Conventional Methods

Many plants or plant-derived compounds with high levels of antioxidants and antiinflammatory, immunomodulatory, and antimicrobial properties could be of great benefit for wound healing. Several studies have documented the use of plant extracts for the development of bioactive wound dressings. The purpose of this chapter is to give an update about the vegetal and bee products, which can be used as bioactive substances in wound dressings or in other formulations for wound healing. The adverse effects of plant and bee extracts, such as contact allergies, are also presented. In order to better exploit the huge reservoir of pharmacologically active plant-derived compounds and extracts, standardized methodology and clinical trials are necessary to give more concrete evidence supporting the use of traditional medicine in wound management.
