First report of biliary tract infection caused by multidrug-resistant Serratia fonticola.

Serratia fonticola is widely distributed in nature and a rare human pathogen. We report the first Case of biliary tract infection due to multidrug-resistant Serratia fonticola in a 78-year-old woman in Vietnam. Bile culture grew S. fonticola. Based on the antibiogram, S. fonticola is resistant to all antibiotic classes. The patient developed septic shock and died.

First report of infective endocarditis caused by Streptococcus pseudoporcinus in Vietnam.

We report a first case of Streptococcus pseudoporcinus bacteraemia causing infective endocarditis in a 40-year-old man in Vietnam. This is the second case of Streptococcus pseudoporcinus infective endocarditis in the literature. The patient was successfully treated by antibiotics, combined with aortic valve replacement.
