New Outbreaks of Salmonellosis in Pig Farms

Salmonellosis is an infection wideley spread in both intensive management and back yard pig farms in Albania. The pathogen agent of this infection is S. cholerasuisi var. Kunzerdof. This patogen was isolated from untreated piglets with antibacterial drugs during septicemic form of infection from several organs and tissues of aborted fetuses, such as: spleen, lungs, mesenteric lymph nodes, liver, and from jejunum, ileum and stomach content. Biochemical confirmation was conducted by using the commercial kit test API 20E, while biovar typisation was realised using the agglutination test with specific sera of S. cholerasuis var. Kunzendorf. Despite the level of the serum titer in aborted sows and survival piglets was at low levels, it represents a determinative diagnostic test. Use of antibacterial prophylaxis in feed or drinking water may reduce the incidence of the disease, but does not prevent infection and/or elimination of S.choleraesuis. This practice is expensive, increases the antimicrobial resistance, and generally is the less acceptable option for the prevention and control of disease. Using specific preventative vaccine produced with the S.cholerasuis var. Kunzerdof C-500 strains, showed effectiveness in both farms. Thus today, we can still say that farms are free from Salmonella infection.
