Diagnostic des infections bactériennes provoquées par Brucella spp, Staphylococcus aureus et Escherichia coli

Abstract

Diagnostic averages for different human infections play an important role in infectious pathology due to their frequency and severity, both in hospitals and populations. Microbiological diagnosis and treatment of these infections requires the correct identification of the etiologic agent for a good therapeutic management. It is in this perspective that we have undertaken to develop an approach to better know the mean of diagnostics and to laboratory of health and to follow a simple, coherent and reliable procedure for a good identification of these different aggressive species, Staphylococcus aureus and Gram-negative bacilli (E. coli and Brucella). In our manuscript, several phases in the identification can be distinguished from the isolation agar until the results are printed. Indeed, it allowed us to make an identification at two levels: - bacteriological study (isolation and biochemical identification of bacteria). - serological study (Rose Bengal test and Wright test for Brucella).
