Pemanfaatan Tanaman Obat Keluarga di Kelurahan Tanah 600, Medan
In February to March 2008, Bali was shocked by the outbreak of diarrhea in Karangasem District, BaiL It was recorded that 600 people were having diarrhea and 5 people were died due to the disease. This outbreak was the first time happened in Bali and the causing pathogen was not yet identified. The aim of this study was to identify the causing pathogen of diarrhea in the outbreak case in Karangasem, as well as to identify the possible transmitting pathway. The trac¬king of outbreak cause was carried out by analyzing water sample taken from communal clean water source, private clean water reservoir, food sample, as well as rectal swab of the patient with the combination of pathogen enrichmenllechnique and specific PCR with Escherichia coli as the target of toxin forming agent. Based on the culture growth from food samples, it was found that 11 from 21 samples were E. coli positive. From samples that E. coli positive, 2 sam. pies that were taken from patient's house were detected a shiga like toxic forming gene, type I and lion the E. coli. The similar shiga like toxin forming gene type I was also detected on samples from patient and samples from water of private family cubang. This shows that E. coli that forms shiga like toxin type I was the dlarrhea causing pathogen in this particular outbreak in Karangasem. Furthermore, it was found out that the ribbon formed by shiga like toxin type I and H differ from the strain of EHEC. Thus, it is 'possible that the strain found in Karangasem was a new strain of E. coli pathogen due to genetic transtorrna. tion on shiga like toxin forming E. coli that was found in Bali.
