title: [Follow-up of occurrence of protozoa in the nasal cavity of pigs in relation to atrophic rhinitis].
abstract: Ninety-five pigs, twelve suffering from atrophic rhinitis, were examined for the presence of protozoans in their nasal cavity. Tritrichomonas suis was isolated only in a single case in a diseased boar representing 1.09% of the set. Amoebae of the Vahlkampfia genus were detected in two pigs (2.1%). The axenic cultures of the two protozoans isolated from the pigs were not pathogenic to laboratory animals. No etiological relation of Tritochomonas suis to atrophic rhinitis was demonstrated.
