title: Monitoring of pigeon paramyxovirus type-1 in organs of pigeons naturally infected with Salmonella Typhimurium.
abstract: An experimental pigeon paramyxovirus (pPMV-1) infection was followed by reverse transcription-nested polymerase chain reaction for 31 days after infection, in 16 organs of inoculated or contact pigeons naturally infected with Salmonella Typhimurium. With two exceptions, both groups presented similar results. Typical nervous signs and a green diarrhoea were observed. The spread of pPMV-1 was relatively quick, all organs being largely positive at 4 days after inoculation or contact. The lung, spleen, caecal tonsils, kidneys and brain, for which almost all tested samples remained positive during most of the experiment, seemed to be the principal targets for virus persistence. However, the virus was significantly recovered later in the brain parts and for longer in the trachea of the contact pigeons than of the inoculated ones.
