Resistance phenotypes and genotypes among multiple-antimicrobial-resistant Salmonella enterica subspecies enterica serovar Choleraesuis strains isolated between 2008 and 2012 from slaughter pigs in Okinawa Prefecture, Japan.

A total of 349 Salmonella enterica subspecies enterica serovar Choleraesuis (S. Choleraesuis) strains, which were isolated between 2008 and 2012 from 349 pigs at two slaughterhouses in Okinawa Prefecture, Japan, were investigated for antimicrobial susceptibility and the presence of antimicrobial resistance genes. All isolates were resistant to at least four antimicrobial agents.

Occurrence of cerebrocortical necrosis in a goat in Okinawa prefecture, Japan.

A 6-month-old male Nubian goat suddenly showed dullness, tachypnea, recumbency and opisthotonus in August 2011 in Okinawa, Japan. The goat was consequently necropsied: gross lesions in the brain included slightly swollen foci of yellowish discoloration on the cerebral hemisphere. Histopathologically, necrosis of the cortex with ischemic changes of neuronal cells was present, and swelling of the vascular endothelium, thickening of the basement membrane and diffuse infiltration of macrophages were observed in the cerebral lesion.
