The process of testing specimens with the culture method by isolation and inoculation of samples for further biochemical tests including Triple Sugar Iron Agar (TSIA), Indole Motility Sulfite (SIM), Methyl Red (MR), Vogas Proskauer (VP), and carbohydrates tests were carried out at the Microbiology Laboratory of Hasanuddin University Hospital. The results showed that the Escherichia coli bacteria were 15 (30%), Klebsiella sp as many as 14 (28%), Enterobacter sp as many as 12 (24%), Proteus mirabilis as much as 4 (8%), Proteus vulgaris as much as 4 (8%), and the bacteria Alcaligenes faecalis only 1 (2%).
