[Rhinopneumonia and equine viral arteritis: seroepidemiological study in the northeast of Tunisia]. / La rhinopneumonie et l'artérite à virus du cheval: etude séro-épidémiologique dans le Nord-Est de la Tunisie.

A seroepidemiological survey was realized in the Nord-Est Tunisia to study the prevalence of complement fixing and neutralizing antibodies to equine rhinopneumonitis and viral arteritis of horse, respectively. Four hundred sera were tested, using complement fixation reaction and seroneutralization test. The results show that 8.75% of sera have antibodies to viral arteritis and only 1.25% are positive for equine rhinopneumonitis.

[Seroepidemiological survey of influenza and infectious anemia in Equidae in northeastern Tunisia]. / Enquête séroépidémiologique sur la grippe et l'anémie infectieuse des equidés dans le nord-est tunisien.

Using the haemagglutination inhibition and immunodiffusion tests, a national serological survey was carried out to detect antibodies to equine influenza (EI) (A/equi/1/Prague 56 and A/equi/2/Miami 63) and equine infectious anaemia (EIA) in horse sera collected in northeastern Tunisia. 533 samples were analysed for EIA antibodies. All were negative. 13.6% of 433 equine sera tested for EI antibodies were positive. These results are discussed and compared with others obtained in Tunisia and bordering countries.
