Abstract

Abstract. The purposes of this research are for molecular characterization and hemagglutination activity test of flagellinprotein of Salmonella typhi. The research samples consist of 7 strains of S. typhi isolates from Central Java (5 strains from Semarang city, 1 strain from Salatiga and 1 strain from Magelang) and 2 strains of S. typhi from Yogyakarta (Doctor Sardjito Hospital and Bethesda Hospital). The undertaking procedures are: 1) PCR and sequencing of fliC genes using primer LPW 1856 and LPW 1857.2) Isolation and separation of flagellin protein using SDS-PAGE. 3) Hemagglutination Activity Test upon human erythrocytes of blood group A, B, AB and O.The results show that 8 strains of S. typhi have a fliC gene size of 1452 to 1488 bp including serovar H1-d, and 1 strain with the size of 1267 bp including serovar H1-J. Flagella protein resulted from SDS-PAGE protein consists of 1-2 major proteins and 1-3 minor proteins with a molecular weight of 16-116 kDa. The results of hemagglutination activity test of flagellin protein show that there are 3 strains of S. typhi (MG-1, SA02.2 and BET) which are able to agglutinate human erythrocytes of bloodgroup A, B, AB and O (2-64HA), 6 other strains show various hemagglutination activities varied

Abstract

This study aimed to analyze the antibacterial activity of Palm oil Honey against Multi  Drug  Resistant  Salmonella  typhi  and  Methicillin-Resistant Staphylococcus aureus by concentration 50%, 60%, 70%, 80%, 90% and 100%. This  research  was  an  experimental  test  with  Posttest  Only  Control  Group Design in an in vitro manner using well diffusion method techniques. The well diffusion method used MHA which made by the well of 5 mm diameter and inserted 200 µ L sample then incubated 35 ± 20C for 24 hours. The results of the study showed the antibacterial activity of Palm oil Honey with zone inhibition against MDR S.typhi 11.4 mm (concentration 90%), 13.4 mm (concentration 100%) and against MRSA 11.7 mm (concentration 100%). The results of zone inhibition of Palm oil honey with concentration 100% against MDR S.typhi was larger than the  zone inhibition  against MRSA. The palm oil honey inhibition zone  against  S.typhi  MDR  bacteria  compared  with  sulfamethoxazole  (SXT) antibiotics with 25 mm inhibition zones was included in the intermediate category and the palm oil honey inhibition zone against MRSA bacteria compared with Tetracycline (TE) antibiotics with 23 mm inhibition zone was included in resistant category. Keywords: Antibacterial Activity, MDR S. typhi, MRSA, Honey, Inhibition Zone

Abstract

Tujuan penelitian ini untuk mendeteksi gen Coa pada S. aureus yang diisolasi dari susu sapi murni di Kelurahan Gedawang. Jenis penelitian ini adalah penelitian deskriptif. Bakteri S. aureus di isolasi dari 15 sampel susu sapi murni. Deteksi gen Coa S. aureus menggunakan primer spesifik  Forward (5´-ATAGAGATGCTGGTACAGG-´3) dan primer Coa Reverse (5´GCTTCCGATTGTTCGATGC-3´).Jumlah isolat S. aureus yang didapatkan dari Isolasi Bakteri sebanyak 3 sampel positif yang memiliki gen Coa dengan hasil produk 756 bp. Hasil pada penelitian ini menunjukkan hasil positif gen Coa sebesar 100%.   Keywords: Staphylococcus aureus, Susu, gen Coa

Abstract

Sepsis atau Systemic Inflammatory Response Syndrome (SIRS) adalah kondisi klinis akut dan serius yang muncul akibat adanya infeksi bakteri di dalam darah. Penelitian ini bertujuan untuk mengetahui keanekaragaman bakteri dan pola resistensi terhadap antibiotik pada sampel darah pasien yang terdiagnosa sepsis  di Laboratorium Klinik Swasta di Semarang pada bulan Mei-Juni tahun 2018. Metode penelitian ini yaitu deskriptif. Hasil penelitian didapatkan sebanyak 42 sampel darah yang ditanam pada media Bact Alert, 12 sampel dinyatakan positif tumbuh. Dari ke 12 sampel tersebut didapatkan 6 jenis bakteri penyebab sepsis yaitu Staphylococcus haemolitycus (25%), Staphylococcus aureus (16,66), Staphylococcus hominis (16,66%), Staphylococcus epidermidis (16,66%), Staphylococcus saprophyticus (8,33%),  Pantoea sp (8,33%), dan Bordetella hinzii (8,33%). Bakteri gram positif resisten terhadap antibiotik Benzylpenicillin, Oxacillin, Penicyline, dan antibiotik betalaktam lainnya. Sedangkan bakteri Pantoea sp resisten terhadap antibiotik Pipericillin/Tazobactam dan Bordetella hinzii resisten terhadap antibiotik Pipericillin/Tazobactam dan Nitrofurantoin
