History of Microbiology in Turkey

1. Ottoman Period: Foundations of Microbiology (1800–1900)

1838–1867: Beginning of Quarantine Practices

· Quarantine systems were established in the Ottoman Empire due to cholera and plague outbreaks.

· In 1839, the first official quarantine organization was established.

· This marks the beginning of infection control before the concept of microorganisms was known.

1867: Modern Medical Education at Mekteb-i Tıbbiye

· Established in 1827 (during the reign of Mahmud II); the spread of germ theory to the Ottoman Empire occurred after 1880.

· The influence of Pasteur and Koch in Europe reached the Ottoman Empire.

· Germ theory began to be learned by Ottoman physicians.

1885: Ottoman Delegation Sent to the Pasteur Institute

1887: First Bacteriology Laboratory

· Established in Istanbul.

· This laboratory is considered the true beginning of microbiology in the Ottoman Empire.

2. Pasteur Influence and Institutionalization (1890–1923)

1893: Establishment of Bakteriyolojihane-i Şahane

· Established in Istanbul.

· It is the first official microbiology institute of the Ottoman Empire.

· Vaccine production and infection research were conducted.

Important figure: Dr. Hüseyin Remzi is one of the pioneers who initiated bacteriology studies in Turkey.

Important figure: Dr. Maurice Nicolle, originally from the Pasteur Institute, established the Bakteriyolojihane in 1893.

1890s: Implementation of the Rabies Vaccine

· Pasteur methods began to be applied in the Ottoman Empire.

1914 – Beginning of Microbiology Education at Darülfünun

· It marks the beginning of academic microbiology.

3. Early Republican Period – Birth of Modern Microbiology (1923–1950)

1927: Establishment of the Refik Saydam Institute of Public Health

· It is the most important turning point in Turkish microbiology.

· Vaccine production began: smallpox vaccine, rabies vaccine, typhoid vaccine, BCG (tuberculosis) vaccine

· Contribution of Refik Saydam: He is considered the founder of public health microbiology in Turkey.

1930s–40s: Establishment of Microbiology Departments at Universities

· Istanbul University

· Ankara University

1931: Turkey’s Vaccine Export

· Smallpox

· BCG

· Rabies vaccines were exported, making Turkey one of the world leaders.

4. Development of Academic Microbiology (1950–1980)

This period marks the increase in scientific production.

Important Developments:

· Clinical microbiology departments were established.

· Microbiology laboratories became widespread in hospitals.

· Antibiotic use and bacterial infection research began.

1960s:

· Studies were conducted on Tuberculosis, Brucella, and Salmonella.

1963: Establishment of TÜBİTAK

· With this step, microbiology studies accelerated directly.

· Academic research funding began.

· Microbiology laboratories increased.

5. Modern Molecular Microbiology Period (1980–2000)

This period marks a technological transformation.

1990–1995: Introduction of PCR Technology to Turkey

· DNA-based microbiology began.

· Molecular diagnosis of viruses became possible.

Increase in Research at Universities:

· Hacettepe University

· Ege University

· Istanbul University

6. Biotechnology and Genomics Era (2000–Present)

This period marks the integration of microbiology with biotechnology.

Developments After 2000

· Genome analyses began to be conducted.

· Microbiome research started.

· Antibiotic resistance research accelerated.

After 2010:

· Industrial microbiology developed.

· Probiotic research increased.

· Biotechnology companies began to be established.

7. COVID-19 Period (2020–2022) – Turning Point of the Modern Era

This period became a critical test for Turkish microbiology.

Actions Taken:

· PCR diagnostic systems were established nationwide.

· Domestic diagnostic kits were developed.

· Viral genome sequencing was performed.

· Domestic vaccine studies were initiated. (TURKOVAC)

8. Post-2022 Period: Acceleration of Microbiome Research

Areas of Study:

· Gut microbiota

· Probiotic bacteria

· Disease–microbiota relationship

· Gut health

Especially, studies on obesity and autoimmune diseases have increased.

9. Post-2023 Period: Synthetic Biology and Advanced Biotechnology

Emerging Areas:

· Gene editing (CRISPR-based studies)

· Microbial production platforms

· Biomaterial production

· Sustainable biotechnology

10. 2024–2026 – Current Period: Translational Microbiology

· Clinical diagnostic technologies

· Personalized microbiome analyses

· Biotechnological product development

· Microbial-based health solutions

Microbiology has now become not only a diagnostic science but also a product development science.

SUMMARY: Microbiology in Turkey evolved in three stages:

1. Epidemic control period (1838–1928)

2. Vaccine production and public health period (1928–1980)

3. Molecular and biotechnology period (1980–present)

Currently, Turkey is rapidly growing especially in the fields of industrial biotechnology, biotechnology, and microbiome research.
