Escherichia coli O157:H7 is one of the pathogenic bacteria causing foodborne disease. The use of lytic bacteriophages can be a good solution to overcome the disease. This study is aimed at isolating lytic bacteriophages from environmental sewage with E. coli O157:H7 bacterial cells. The sample used in this study was eight bacteriophages, and the technique used in identifying E. coli O157:H7 carriers of the stx1 and stx2 genes was PCR. The double layer plaque technique was used to classify bacteriophages. Plaque morphology, host specificity, and electron micrograph were used to identify the bacteriophages. The result obtained plaque morphology as a clear zone with the largest diameter size of 3.5 mm. Lytic bacteriophage could infect E. coli O157:H7 at the highest titer of 10 × 10 8   PFU / mL . Bacteriophages have been identified as Siphoviridae and Myoviridae. Phage 3, phage 4, and phage 8 could infect Atypical Diarrheagenic E. coli 1 (aDEC1) due to their host specificity. The Friedman statistical tests indicate that lytic bacteriophage can significantly lyse E. coli O157:H7 ( p = 0.012 ). The lysis of E. coli O157:H7 by phage 1, phage 2, phage 3, and phage 5 bacteriophages was statistically significant, according to Conover’s posthoc test ( p < 0.05 ). The conclusion obtained from this study is that lytic bacteriophages from environmental sewage could lyse E. coli O157:H7. Therefore, it could be an alternative biocontrol agent against E. coli O157:H7 that contaminates food causing foodborne disease.

A good strategy to conquer the Escherichia coli-cause food-borne disease could be bacteriophages. Porins are a type of β-barrel proteins with diffuse channels and OmpA, which has a role in hydrophilic transport, is the most frequent porin in E. coli; it was also chosen as the potential receptor of the phage. And the Rz/Rz1 was engaged in the breakup of the host bacterial external membrane. This study aimed to analyze the amino acid of OmpA and Rz/Rz1 of lytic bacteriophage from Surabaya, Indonesia. This study employed a sample of 8 bacteriophages from the previous study. The OmpA analysis method was mass spectrometry. Rz/Rz1 was analyzed using PCR, DNA sequencing, Expasy Translation, and Expasy ProtParam. The result obtained 10% to 29% sequence coverage of OmpA, carrying the ligand-binding site. The Rz/Rz1 gene shares a high percentage of 97.04% to 98.89% identities with the Siphoviridae isolate ctTwQ4, partial genome, and Myoviridae isolate cthRA4, partial genome. The Mann–Whitney statistical tests indicate the significant differences between Alanine, Aspartate, Glycine, Proline, Serine ( p = 0.011 ), Asparagine, Cysteine ( p = 0.009 ), Isoleucine ( p = 0.043 ), Lysine ( p = 0.034 ), Methionine ( p = 0.001 ), Threonine ( p = 0.018 ), and Tryptophan ( p = 0.007 ) of OmpA and Rz/Rz1. The conclusion obtained from this study is the fact that OmpA acts as Phage 1, Phage 2, Phage 3, Phage 5, and Phage 6 receptors for its peptide composition comprising the ligand binding site, and Rz/Rz1 participates in host bacteria lysis.

Salmonella enterica merupakan salah satu bakteri patogen penyebab gastroenteritis yang ditransmisikan melalui air dan makanan terkontaminasi yang sering terjadi pada negara berkembang. Beberapa strain Salmonella enterica multi-resisten terhadap berbagai antibiotika. Bakteriofag litik pada famili Siphoviridae dapat menjadi solusi alternatif dalam mengurangi kejadian gastroenteritis oleh Salmonella enterica. Tujuan penelitian ini adalah untuk mengisolasi, mengetahui kemampuan bakteriofag litik Lytic Bacteriophage 1 (LB1) dalam melisis inangnya yaitu Salmonella enterica penyebab gastroenteritis, serta mengetahui karakterisasi bakteriofag litik LB 1 sebagai biokontrol penyakit gastroenteritis. Bakteriofag litik diisolasi dari pembuangan limbah domestik menggunakan teknik double layer plaque. Bakteriofag litik diidentifikasi berdasarkan morfologi plak, struktur litik, inang, aktivitas lisis sel bakteri Salmonella enterica, stabilitas dalam kondisi buffer yang berbeda dan karakterisasi protein. Bakteriofag litik LB1 hanya menginfeksi sel Salmonella enterica. Hasil pemeriksaan dengan menggunakan Transmission Electron Microscope (TEM), bakteriofag litik LB1 termasuk ke dalam famili Siphoviridae. Morfologi kepala hexagonal-icosahedral berdiameter 72.7 nm, dengan ekor non-kontraktil berdiameter 17.3 nm dan panjang 100 nm. Bakteriofag litik LB1 memiliki stabilitas terbaik dalam buffer Ringers suhu 4 oC yang ditunjukkan dengan penurunan plak sebesar 28% setelah 3 minggu penyimpanan. Hasil pengujian efektivitas menunjukkan bahwa bakteriofag litik LB1 dapat mengurangi populasi sel Salmonella sebanyak 67,12% setelah 8 jam inkubasi. Bakteriofag litik LB1 memiliki 8 protein yang berbeda dengan berat molekul yang beragam 11.4 kDa, 19.6 kDa, 23 kDa, 33 kDa, 58.3 kDa, 77 kDa, 94.5 kDa, 133 kDa. Studi ini menunjukkan bahwa bakteriofag litik LB1 yang diisolasi pembuangan limbah domestik dapat secara efektif mengurangi Salmonella enterica dengan cara melisis sel bakteri. Bakteriofag litik LB1 berpeluang dapat digunakan sebagai biokontrol penyakit gastroenteritis yang disebabkan oleh Salmonella enterica. Stabilitas terbaik bakteriofag litik LB1 pada penyimpanan dalam buffer Ringer di suhu dingin (4oC), memiliki karakterisasi famili Siphoviridae, dapat mengurangi Salmonella enterica sebanyak 67.12% setelah 8 jam inkubasi, dan memiliki berat molekul 11.4-133 kDa.     Salmonella enterica is one of pathogenic bacteria causing gastroenteritis transmitted by water and food contamination which commonly occur in developing country.  Some study reported that Salmonella serovar enterica strains were multi-resistant to various of antibiotics. Lytic bacteriophage in Siphoviridae family offered a good solution to reduce gastroenterytis disease caused by Salmonella enterica. This  reseach aim was to isolate, effectivity test of LB 1 and to characterize lytic bacteriophage as biocontrol of gastroenterytis. Methodology and results were LB1 lytic bacteriophage was isolated from domestic waste using double layer plaque technique, was determined by the plaque morphology, the structure, the host range, the activity to lyse bacterial host cells, the stability of phage on different buffer conditions, and the protein characterization. The results showed that LB1 only infects Salmonella enterica. Based on Electron Microscope Observation showed that LB1 is grouped into Siphoviridae. It has hexagonal-icosahedral head with 72.7 nm in diameter and long-non contractile tail with 100 nm in diameter. LB1 had a good storage stability in Ringers buffer at low temperature (40C), with viability of bacteriophage decreased by 28% after 3 weeks of storage. The effectiveness showed that LB1 could reduce Salmonella enterica by 67.12% after 8 hours of incubation. LB 1 has different proteins with molecular weights: 11.4 kDa, 19.6 kDa, 23 kDa, 33 kDa, 58.3 kDa, 77 kDa, 94.5 kDa, and 133 kDa. The conclusion was LB1 was isolated from sewage water were identified to reduces Salmonella enterica effectively with concentration of 8.2x108 CFU/mL. LB 1 can be used as a biocontrol of gastroenterytis caused by Salmonella enterica, LB 1 has the best stability in buffer ringers in cold temperatures (4oC) and proven as Siphoviridae family, reduced Salmonella enterica by 67.12% after 8 hours of incubation, and has protein molecule with molecular weight 11.4 to 133 kDa.
