San Lazaro Hospital – Nagasaki University (SLH-NU) Collaborative Research Office and Laboratory


The San Lazaro Hospital – Nagasaki University (SLH-NU) Collaborative Research Office and Laboratory was established in 2015 between San Lazaro Hospital (Manila, Philippines) and the School of Tropical Medicine and Global Health (Nagasaki, Japan).

We aim to conduct impactful research in infectious and tropical diseases as well as supporting the training and education of clinicians and researchers from the Philippines, Japan, and beyond.

We welcome external collaborations. Please reach out to us via the contact details below.

About San Lazaro Hospital

Founded in 1577 in Manila, the Philippines, San Lazaro Hospital is a 500-bed capacity dedicated special National Medical Center for Infectious Diseases. It is involved in healthcare service delivery for underprivileged groups suffering from infectious and tropical diseases.

San Lazaro Hospital hosts the National Reference Laboratory – STD AIDS Cooperative Central Laboratory, an animal bite treatment center, a facility for the programmatic management of drug resistant tuberculosis, and a HIV screening and testing hub, in addition to its inpatient services. SLH is also a Philippine Society for Microbiology and Infectious Diseases-accredited training center for adult infectious diseases.


Our team includes research nurses, medical technologists, a secretary, a data manager, a research clinician, and an office manager. A dedicated SLH-NU coordinator, under the SLH administration, liaises the activities between SLH and NU. The laboratory is able to conduct various serological and molecular tests, MALDI-ToF, genetic sequencing, and store samples for future analyses.

Research themes have included etiology of fever, and diseases such as leptospirosis, diphtheria, measles, HIV, tuberculosis, rabies, dengue, and typhoid. We have experience of conducting prospective observational studies among patients presenting with fever or respiratory tract infections. Examples of projects include:

  1. Community Acquired Bacteremia (CAB) study: launched in 2015, the CAB study aims to characterize the etiology of fever (particularly bacterial bloodstream infection) and antimicrobial resistance patterns in admitted patients
  2. Acute Respiratory Infection study: launched in 2020, the ARI study aims to describe the epidemiology and clinical features of acute respiratory infection (including COVID-19) among patients, healthcare workers, and household contacts in SLH.
  3. Central Nervous System Infection study: the CNSi study is being developed to characterize the clinical, microbiological, and molecular epidemiology of community acquired central nervous system infections.

In addition, we support the conduct of research and case reports by SLH fellows and consultants and affiliated graduate students and academics from NU.

Education and training

We organize the Philippine Tropical Medicine Course; a two-week practical clinical and public health course that consists of bedside teaching, lectures and discussion, and fieldwork in the communities. Further information is available here.
