Methicillin-resistant Staphylococcus aureus (MRSA) merupakan salah satu strain bakteri Staphylococcus aureus yang sudah mengalami resistensi terhadap antibiotika. MRSA merupakan penyebab utama infeksi nosokomial dan berbagai sindrom klinik. Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri teh kombucha dan mengetahui perbedaan daya antibakteri teh hitam kombucha dan teh hijau kombucha dalam menghambat MRSA.  Kombucha teh hitam dan kombucha teh hijau dibuat dengan fermentasi cair. Uji antibakteri teh kombucha pada MRSA dilakukan dengan metode difusi sumuran. Perbedaan antibakteri teh hitam kombucha dan teh hijau kombucha dianalisis menggunakan uji-t.  Teh hijau kombucha memiliki kadar asam total yang lebih tinggi dengan pH yang lebih rendah dibandingkan teh hitam kombucha. Teh hitam kombucha dan teh hijau kombucha mempunyai aktivitas antibakteri pada MRSA yang ditunjukkan dengan terbentuknya zona irradikal dengan diameter 14 ±  0,85 mm dan 17,1 ± 0,93 mm. Zona irradikal menunjukkan aktivitas teh hitam kombucha dan teh hijau kombucha dikategorikan lemah.  Oleh karena itu, teh kombucha belum efektif sebagai antibakteri terhadap MRSA.  Hasil uji-t menunjukkan terdapat perbedaan aktivitas antibakteri antara teh hitam kombucha dan teh hijau kombucha pada Methicillin-resistant Staphylococcus aureus (MRSA).","PeriodicalId":53348,"journal":{"name":"Jurnal Biologi Udayana","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43011909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Penggunaan CCl4 secara terus menerus dapat memicu terbentuknya radikal bebas sehingga berpotensi merusak organ hati dan ginjal. Tanaman sirsak (Annona muricata L.) salah satu tanaman yang dapat digunakan sebagai obat alternatif karena mengandung senyawa antioksidan yang dapat mencegah pembentukan radikal bebas. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak daun sirsak terhadap gambaran histologi hati dan ginjal mencit (Mus musculus L.) yang diinduksi karbon tetraklorida. Penelitian ini menggunakan Rancangan Acak Lengkap dengan 24 ekor mencit jantan yang dikelompokkan menjadi 4 perlakuan yaitu kontrol negatif (K-) diberi larutan Na-CMC 0,5%, kontrol positif (K+) diinduksi CCl4 0,007 mL/20g BB yang dilarutkan dalam minyak kelapa 0,1 mL, dan dua perlakuan yang diinduksi CCl4 0,007 mL/20g BB serta diberi ekstrak daun sirsak dosis 100 mg/kg BB (P1) dan 200 mg/kg BB (P2). Parameter yang diamati pada histologi hati yaitu degenerasi melemak, degenerasi hidropik, nekrosis, kongesti, serta infiltrasi sel radang. Parameter yang diamati pada histologi ginjal yaitu degenerasi melemak, nekrosis, infiltrasi sel radang, dan pembengkakan glomerulus. Hasil penelitian menunjukkan terjadi penurunan kerusakan yang berbeda nyata (p<0,05) pada P1 dan P2 dibandingkan dengan kontrol positif (K+) pada sayatan histologi hati dan ginjal, sehingga dapat disimpulkan bahwa pemberian ekstrak daun sirsak mampu memperbaiki kerusakan hati dan ginjal setelah diinduksi karbon tetraklorida.","PeriodicalId":53348,"journal":{"name":"Jurnal Biologi Udayana","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41349907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kerusakan pada produk daging olahan diakibatkan karena adanya pertumbuhan mikroorganisme. Menanggulangi hal tersebut, perusahaan pengolahan daging banyak menambahkan bahan tambahan pangan (BTP) yaitu natrium nitrit (NaNO2). Akumulasi nitrit yang berlebih dalam tubuh dapat menimbulkan efek yang merugikan pada sistem reproduksi. Penelitian oleh Pavlova et al. (2017) menemukan terjadi penurunan berat epididimis dan pengurangan jumlah spermatoa tikus yang diberi paparan NaNO2 tinggi. Rumput laut Eucheuma cottoni mengandung antioksidan yang dapat menetralkan sifat oksidatif yang ditimbulkan oleh NaNO2. Penelitian ini dilakukan untuk mengetahui pengaruh ekstrak rumput laut Eucheuma cottoni terhadap kadar Malondialdehid (MDA) dan spermatozoa pada tikus putih (Rattus norvegicus L.) jantan yang diinduksi NaNO2. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari kontrol negatif (K-), kontrol positif (K+), perlakuan dosis 1 (P1), perlakuan dosis 2 (P2) dan perlakuan 3 (P3).  Kontrol negatif (K-) diberikan aquades sedangkan kontrol positif diberikan natrium nitrit dosis 22,5 mg/kg BB. Perlakuan dosis 1,2 dan 3 diberikan metode kombinasi natrium nitrit dan ekstrak rumput laut dosis 150 mg/kgBB/hari (P1), 300 mg/kgBB/hari (P2), dan 450 mg/kgBB/hari (P3). Pemberian perlakuan dilakukan selama 45 hari. Adapun variabel penelitian terdiri dari kadar MDA (Malondialdehid) pada serum dan kualitas spermatozoa meliputi integritas membran, viabilitas, motilitas dan morfologi spermatozoa dari tikus putih jantan. Analisis data dilakukan melalui uji statistik One Way Anova dan dilanjutkan dengan uji Duncan. .
