03-24-23  WORLD TB DAY commemorates the announcement in 1882 when Dr. Robert Koch discovered the Mycobacterium tuberculosis, the bacilli that causes tuberculosis (TB). This date is an opportunity to highlight research on TB prevention and control and educate the public about the worldwide impact of TB. In 2021, an estimated 10.6 million people fell ill with tuberculosis (TB) worldwide. Six million men, 3.4 million women and 1.2 million children – progress against TB was lost during the Covid-19 epidemic, with TB control worsening in many countries impact by Covid-19 (WHO, Oct 2022). TB is present in all countries and age groups. But TB is curable and preventable.

On this occasion we announce the ongoing efforts of the TB Regional Prospective Observational Research Tuberculosis (TB-RePORT) Consortium, supported by the US National Institute of Allergy and Infectious Diseases (NIAID) and bilateral funding from host countries – some supported since 2013. This consortium across 8 countries (Brazil, China, India, Indonesia, Philippines, S Africa, S Korea and Uganda), representing approximately 70% of the world’s TB epidemic, establishes a platform for future combined or comparative studies between bench science and clinical research that has been highly productive in national and international research aims helping with control and prevention.

Rutgers University is the ongoing Coordinating Center for this Consortium, having this central coordination effort since 2020, now ongoing till 2028. Please visit for detailed information about these ongoing efforts to better control and eradicate tuberculosis worldwide.

02-05-23  Ranjeet Kumar, Afsal Kolloli and colleagues describe their single-molecule FISH approach for imaging the architecture of tuberculosis granulomas in rabbits and macaques ( Granulomas are created by immune cells around mycobacteria to limit both bacterial dissemination and inflammation in the lung.  The scientists classified immune cells based on mRNA expressions and mapped their distributions.  This approach paves the way for more comprehensive spatial transcriptomic studies that will produce better understanding of the Tuberculosis disease.

11-17-21  Fred Russell Kramer and Diana Vargas published a research article in Nature’s Scientific Reports.  Their study shows that SuperSelective primer pairs enhance the sensitivity of multiplex PCR assays that identify and quantitate somatic mutations in liquid biopsies obtained from patients with cancer, thereby enabling the choice of a targeted therapy, the determination of its effectiveness over time, and the substitution of a more appropriate therapy as new mutations arise. To access the article, please visit:

10-08-21  LaTasha Fraser, Ryan Dikdan and Sanjay Tyagi have a new paper just published in PNAS.  Here they explored the molecular origins of the enigmatic “noise” in gene expression.  The paper shows that mammalian genes are not expressed in a steady and continuous manner, but are expressed in episodic bursts, because the regulatory regions of genes are normally hidden in impervious chromatin.  Random breathing events in chromatin provide intermittent access to factors that turn the genes on and thereby render the gene expression intermittent.  To access the paper, please visit:

04-05-19   Dr. Xilin Zhao’s group published a paper in the Proceedings of National Academy of Sciences USA that revealed a fundamental aspect of antibiotic action: the reactive oxygen species (ROS) produced by bacteria in response to severe stress is self-amplifying. Once a threshold is passed, the damage caused by ROS stimulates the production of more ROS; death is inevitable. The work also showed unequivocally that ROS arising from antimicrobial treatment causes death rather than being an incidental side-product. The conclusions emerged from the popular misconception that bacteria are thought to be dead at the time they are plated on agar to measure survival following antibiotic treatment: they can actually still be alive, dying on the drug-free agar plates due to self-amplifying ROS accumulation. This work should have a major impact on our understanding of how bacteria die in response to diverse types of lethal insult. The paper can be accessed at:

02-13-19  Dr. Chaoyang Xue received an award from the New Jersey Health Foundation, which will aid in studies to better understand the mechanism of lipid flippase-mediated antifungal drug resistance.  The ultimate aim is to identify novel drug targets and to expand the use of existing drugs against currently resistant fungal infections.
