Zoonoses bactériennes émergentes

Improved epidemiological surveillance and use of new diagnostic techniques has enabled the recent discovery or provided improved information on existing infections of numerous zoonoses of bacterial origin. The main factors causing emergence or re-emergence include changes to the environment, intensive production of food products and growth of international transport of these products, human demography and behaviour, as well as bacterial adaptation to a new environment. An emergence or re-emergence of bacterial zoonoses originating from food (salmonellosis, Escherichia coli infections, etc.). resulting from pets (salmonellosis, plague, Q fever), associated with immunodepression (Rhodococcus equi infection, Bartonella henselae infection, etc.) or due to vectoral transmission (Lyme disease, ehrlichiosis, etc.) has been observed (4 figures, 1 table, 1 box, 43 references).
