RESUMO:

Salmonella spp. is an important bacterial pathogen of poultry and is responsible for significant economic losses of poultry in many parts of the world. Salmonella Gallinarum (SG) is a specific serovar of birds that causes great damages to cause the Fowl Typhoid (FT), a notifiable disease that can manifest of acute or chronic form and determine septicemia in birds. In the State of Santa Catarina, as of 2012, there were 96 notifications to the Official Veterinary Service (OVS) of FT in Santa Catarina. The characterization of these strains is of great importance for evaluations of epidemiology and association of risk factors. The objective of this study was to study the genetic diversity of SG from TA cases in Santa Catarina, seeking to identify similarity or dissimilarity between strains isolated from foci. For this study, 56 SG strains from the National Agricultural and Livestock Laboratory (LANAGRO) - Campinas, which at Embrapa Pigs and Poultry were submitted to PFGE analysis according to the protocol standardized by the Pulsenet CDC (Centers for Disease Control and Prevention). A questionnaire was developed to identify predisposing factors for entry and dissemination of SG in farms. The questionnaire consisted of eighteen closed binary questions (yes or no) and was referred to the veterinary surgeons of the SVO responsible for the care of the properties, where there were outbreaks of SG. Through the PFGE technique and subsequent elaboration of a dendrogram, a prevalent genotypic profile (57.1%) of SG was identified in the samples analyzed. This result suggests that in the state of SC, an endemic clone occurs, the dissemination of which is possibly conveyed to the transport of infected birds between regions, and it has not been possible to identify and associate predisposing factors analyzed in the questionnaires to the occurrence of SG outbreaks.
