Abstract :
Bacterial culture is a method of multiplying bacteria on culture media by
culturing in an aseptically controlled laboratory, to determine the type of
bacteria. However, in the STIKES Nasional bacteriology laboratory, there are 8
specises of gram-negative bacterial culture samples such as Escherichia coli,
Klebsiella pneumoniae, Klebsiella oxytoca, Serratia marcescens, Salmonella
typhosae, Proteus mirabilis, Providencia rettgeri and Pseudomonas aeruginosa.
Where the bacterial culture is used periodically as a sample for bacterial
examination in the bacteriological laboratory practicum at STIKES Nasional
where the sampel has never been monitored for resistance to the antibiotic
Cefotaxime. The purpose of this study was to determine the gram-negative
bacteria Escherichia coli, Klebsiella pneumoniae, Klebsiella oxytoca, Serratia
marcescens, Salmonella typhosae, Proteus mirabilis, Providencia rettgeri and
Pseudomonas aeruginosa bacteriology laboratory culture samples from National
STIKES that are resistant to Cefotaxime antibiotics.
This study uses a descriptive design. This research was conducted at the
Bacteriology Laboratory of the National College of Health Sciences and the time
of this research was carried out on March 22-16 April 2021. The samples of this
study were 8 species of gram-negative bacteria using the antibiotic Cefotaxime
30?g. Disc diffusion method (Kirby Bouer test) and the sampling technique used
is purposive sampling.
The results of this study showed that the bacteria Klebsiella pneumoniae,
Klebsiella oxytoca and Pseudomonas aeruginosa were resistant to the antibiotic
Cefotaxime 30 g with the resulting radical zones of 6 mm, 22 mm and 19 mm,
respectively. For bacteria Serratia marcescens, Salmonella typhosae, Proteus
mirabilis and Providencia rettgeri were still sensitive to the antibiotic Cefotaxime
30 g with the results of radical zones 31 mm, 33 mm, 28 mm and 54 mm,
respectively. While Escherichia coli bacteria intermediate to Cefotaxime 30 g
radical zone formed by 24 mm.
Bacteria Klebsiella pneumoniae, Klebsiella oxytoca and Pseudomonas
aeruginosa aeruginosa were resistant to the antibiotic Cefotaxime 30 g. The
bacteria Serratia marcescens, Salmonella typhosae, Proteus mirabilis and
Providencia rettgeri were still sensitive to the antibiotic Cefotaxime 30 antibiotikg
and the intermediate Escherichia coli bacteria to Cefotaxime 30 g.
