Abstract: Surgical site infection (SSI) is the main surgery complication which can increase morbidity, mortality, as well as the hospital cost. The prevalence of SSIs at a health care reflects its sevice quality. This study was aimed to obtain the bacterial profile of SSIs among multitraumatic patients at Prof. Dr. R. D. Kandou Hospital from June through December 2016. This was a descriptive study with a cross sectional design. Pus was obtained from SSIs of laparotomy and ORIF operation wounds, and was further examined with PCR. The results showed that of 16 samples, 3 samples were negative (18.75%) and 13 samples were positive (81.25 %). The PCR test showed that the highest percentage of bacteria was Pseudomonas aeruginosa (6 samples; 46.1%), followed by Escherichia coli (2 samples; 15.4%), and Enterobacter hormaechei, Alcaligenes faecalis, Enterobacter cloacae, Bacteroides fragilis as well as Proteus mirabilis (each of 1 sample; 7.7%). Conclusion: Based on the PCR test, there were 7 types of bacteria at the SSIs of multitraumatic patients at Prof. Dr. R. D. Kandou Hospital Manado, all of them were Gram negative, and the most common type was Pseudomonas aeruginosa.Keywords: bacterial profile, PCR, SSIs, multitraumatic patientsAbstrak: Infeksi luka operasi merupakan salah satu komplikasi utama operasi yang dapat meningkatkan morbiditas, mortalitas, dan biaya perawatan penderita di rumah sakit. Angka kejadian infeksi luka operasi pada suatu institusi penyedia pelayanan kesehatan mencerminkan kualitas pelayanan pada institusi tersebut. Penelitian ini bertujuan untuk mendapatkan pola kuman infeksi luka operasi pada pasien multitrauma di ruang perawatan bedah RSUP Prof. Dr. R. D. Kandou selama bulan Juni-Desember 2016. Jenis penelitian ialah deskriptif dengan desain potong lintang. Apusan pus diambil dari luka operasi terinfeksi pada tindakan laparotomi dan ORIF kemudian diperiksa dengan PCR. Hasil penelitian memperlihatkan dari 16 sampel yang diteliti ditemukan 3 sampel negatif (18,75%) dan 13 sampel positif (81,25 %). Berdasarkan hasil PCR ditemukan pertumbuhan kuman terbanyak ialah Pseudomonas aeruginosa sejumlah 6 sampel (46,1%), diikuti Escherichia coli sejumlah 2 sampel (15,4%), serta Enterobacter hormaechei, Alkaligenes faecalis, Enterobacter cloacae, Bacteroides fragilis, dan Proteus mirabilis, masing-masing sejumlah 1 sampel (7,7%). Simpulan: Berdasarkan hasil PCR didapatkan 7 jenis kuman pada infeksi luka operasi dari pasien multitrauma di RSUP Prof. Dr. R. D. Kandou Manado, kesemuanya tergolong bakteri Gram negatif, dan yang tersering ialah Pseudomonas aeruginosa.Kata kunci: pola kuman, PCR, infeksi luka operasi, pasien multitrauma

ABSTRACT Many studies have evaluated the antimicrobial activity of natural products against various microorganisms, but to our knowledge there have been no studies of the possible use of natural products for their antimicrobial activity against Enterobacter hormaechei. In this study, we investigated vanillic acid (VA) for its antimicrobial activities and its modes of action against carbapenem-resistant E. hormaechei (CREH). The MIC of VA against CREH was determined by the agar diffusion method. The antibacterial action of VA against CREH was elucidated by measuring variations in intracellular ATP concentration, intracellular pH, membrane potential, and cell morphology. Moreover, the efficacy of VA against biofilm formation and VA damage to CREH cells embedded in biofilms were further explored. Our results show that VA was effective against CREH with a MIC of 0.8 mg/mL. VA could rupture the cell membrane integrity of CREH, as measured by a decrease of intracellular ATP, pH, and membrane potential, along with distinctive alternations in cell morphology. In addition, VA exerted a remarkable inhibitory effect on the biofilm formation of CREH and also killed CREH cells within biofilms. These findings show that VA has a potent antibacterial and antibiofilm activity against CREH and, hence, has the potential to be used clinically as a novel candidate agent to treat CREH infections and in the food industry as a food preservative and surface disinfectant.
