Abstract:
In medical analysis laboratories, techniques for identifying bacteria are currently becoming more and more numerous. The objective of this study is to compare the 2 bacterial identification systems Bis NEG-D and Api 20E for the identification of gram-negative bacilli. This is a qualitative evaluation of the Bis NEG-D compared to the gold standard Api 20E. During the study period, 32 Gram-negative bacilli isolates were identified simultaneously using Api 20E and Bis NEG-D. The samples are represented by 12 (37.5%) blood samples for blood culture, 12 (37.5%) urine samples for cytobacteriological examination of the urine, 06 (18.8%) pus samples for bacteriological examination of pus, a sample of the cerebrospinal fluid (3.1%) and a vaginal sample (3.1%).The bacteria identified were represented by Enterobacter spp, Escherichia col,i Klebsiella pneumonia, Shigella spp, Salmonella typhi, Acinetobacter baumannii, Pseudomonas spp, Proteus mirabilis, Raoultella ornithinolytica and Bukholderia cepacia. This study showed a concordance of 90.6% (29/32) and a discordance of 9.4% (3/32) between the results of Api 20E and Bis NEG-D. Concerning the probability scores, they vary between 95% to 100% for Api 20E and between 79.3% to 100% for Bis NEG-D. This study also compared the pros and cons of using Api 20 E and Bis NEG-D. The Bis-NEG-D is valid and can be used by medical analysis laboratories like the Api 20E, especially if these laboratories do not need to perform a lot of bacterial identification tests.
