Update on Mycobacterium bovis infections in France: 4 cases reports]

Mycobacterium bovis (M. bovis) is a cause of zoonosis. It is rare in developed countries since cattle control. We report four cases of M. bovis infection in people aged more 60 years. They were probably infected during infancy, consuming unpasteurized milk. It is the main transmission mode in developing countries where veterinary controls aren't made. M. bovis infections clinical aspects are varied and treatment is complicated by natural pyrazinamide resistance. Recent diagnostic methods using molecular biology are quick and specific and facilitate identification.
