1. Salmonella Gallinarum strains isolated from a southern Brazil fowl typhoid outbreak were subjected to phenotypic and genotypic analyses to identify genetic elements that could improve prevention and control strategies. 2. Whole-genome sequencing revealed the presence of the aac(6')-Iaa gene, conferring aminoglycoside resistance, along with novel chromosomal point mutations, including the first detection of parE p.S451F in Salmonella Gallinarum. 3. Additionally, IncFII(S) plasmid replicons, Salmonella pathogenicity islands and 105 virulence genes associated with cell adhesion, invasion and antimicrobial peptide resistance were identified. 4. These findings shed light on the molecular mechanisms of fowl typhoid and provide crucial insights into emerging antimicrobial resistance and virulence factors. [ABSTRACT FROM AUTHOR] more...

Choledochal cyst or biliary tract cyst is a pathological condition characterized by abnormal dilation of the hepatobiliary system. In veterinary medicine, case descriptions and histological characterizations of this biliary malformation are scarce, requiring reliance on data from human medicine. A presumptive diagnosis typically involves imaging studies, with histopathological examination required for confirmation. Treatment often involves surgical intervention to remove the cyst and restore normal biliary function. A 15-year-old mixed-breed domestic female cat presented with vomiting and anorexia. Ultrasonographic examination revealed a dilation adjacent to the caudal aspect of the gallbladder. The patient underwent surgical intervention, during which a sacculation in the cystic duct region was identified and completely excised. Histopathological analysis confirmed the diagnostic suspicion of a biliary tract cyst. Despite the limited veterinary literature, the success of the surgical intervention, involving complete cyst removal, was evident. The patient remains stable and fully recovered twelve months post-surgery., Competing Interests: Declarations. Ethical approval: The work described in this manuscript involved the use of a non-experimental (owned) animal. High, internationally recognized standards (“best practices”) of veterinary clinical care for patients were always followed. Consent to participate: Informed consent was obtained from the owner or legal custodian of the animal described in this work for all procedures undertaken. No animals or people are identifiable within this publication, and therefore additional informed consent for publication was not required.
