Serratia marcescens septicemia associated with infusion of an amino acid solution in two horses.

The study investigates the occurrence of a bacterial infection in two horses after they were given an intravenous infusion of an amino acid solution. It is discovered that identical strains of a bacteria known as Serratia marcescens were responsible for the infection, and that the horses recovered following treatment.

Introduction and Objective of the Study

• The objective of the research was to explore and understand the connection between the administration of an intravenous amino acid solution and subsequent development of septicemia, a severe bacterial blood infection, in two clinically normal horses.

Findings and Evidence

• The researchers identified Serratia marcescens, a type of bacteria, in the blood samples from both horses. The presence of this bacteria indicated infection, implicating septicemia.
• From the identical antibiograms and plasmid biochemistry of the bacterial isolates, it was inferred that both the horses were infected by the same strain of bacteria.
• The findings strongly suggested that the intravenous amino acid solution administered to the horses served as the source of the bacterial infection, leading to the development of septicemia.

Treatment and Recovery

• The horses received both supportive care and antimicrobial treatment to combat the bacterial infection.
• Following the treatment prescribed by the researchers, both horses were seen to recover from the infection, demonstrating the effectiveness of the chosen therapeutic measures.

Conclusion and Implication

• The study highlights the possibility of bacterial contamination in intravenous solutions like the amino acid infusion used, which can lead to severe outcomes like septicemia.
• It underscores the importance of taking preventive measures to avert such infections. Additionally, it emphasizes the need for intensive care and prompt treatment in case such a bacterial infection does occur.
