Alberto Barton

Alberto Leonardo Barton Thompson (1870–1950) was a Peruvian microbiologist known for his discovery of the bacterium Bartonella bacilliformis, the causative agent of Carrion's disease. His work laid the foundation for understanding this infectious disease, which is endemic to certain regions of Peru.

Early Life and Education

Alberto Barton was born in Lima, Peru in 1870. He pursued his medical studies at the National University of San Marcos, where he developed an interest in microbiology and infectious diseases. After completing his medical degree, Barton continued his studies in Europe, where he gained further expertise in bacteriology.

Discovery of Bartonella bacilliformis

In the early 20th century, Barton returned to Peru and began working at the Guadalupe Hospital in Lima. It was here that he conducted his groundbreaking research on the disease known as Oroya fever, a severe febrile illness that was affecting workers constructing the Central Railway of Peru.

Barton meticulously examined blood samples from patients and identified a previously unknown bacterium, which he named Bartonella bacilliformis. His discovery was crucial in understanding the etiology of Carrion's disease, which manifests in two distinct phases: Oroya fever and Verruga peruana.

Contributions to Medicine

Barton's identification of Bartonella bacilliformis was a significant advancement in tropical medicine. His work not only helped in diagnosing and treating Carrion's disease but also contributed to the broader field of bacteriology.

In addition to his research, Barton was a dedicated educator, teaching at the National University of San Marcos and mentoring future generations of Peruvian physicians and scientists.

Legacy

Alberto Barton's contributions to medical science have been recognized both in Peru and internationally. The genus Bartonella, which includes several species of bacteria that cause disease in humans and animals, was named in his honor.

Barton passed away in 1950, but his legacy continues through ongoing research into Bartonella infections and their impact on public health.
