Salmonella enterica subspecies enterica serovar Choleraesuis is rarely
detected in Europe, but the clinical disease in pigs, was reported in
wild boars. Salmonellosis caused by S. Choleraesuis has never been
confirmed in Serbia, as in many other countries in Europe. In April
2019, on one large farrow-to-finish pig farm, an increase in mortality
in weaned piglets with lethargy, anorexia, pyrexia and respiratory
distress was reported. Gross pathology revealed dermal cyanosis,
mesenteric lymphadenopathy, splenomegaly, hepatomegaly, interstitial
pneumonia and colitis. By direct culturing of lung, liver, spleen and
lymph nodes S. Choleraesuis variant Kunzendorf was isolated. This is the
first report on the detection of S. Choleraesuis in domestic pigs in
Serbia and re-appearance of salmonellosis due to S. Choleraesuis after
decades of absence of disease on pig farms in Europe, which provides
useful information about the epidemiology of this agent on the European
continent. However, the definitive source for this outbreak and origin
of infection still have to be elucidated.
