Our ‘killer’ cells’ role in life-long flu vaccine
Dr Nerissa Hannink
In the battle against the flu, our ‘killer’ immune cells are like the body’s border control. These microscopic killers are white blood cells that can maintain a memory of previous exposure to a flu strain. And if they recognise an invader, these cells start an immune response to target and kill off the virus – stopping the infection. But the problem is that there are three types of influenza virus that can infect humans – strains A, B and C. They circulate in the human population globally, and mutate every flu season.
Bacteria develop tougher membranes to resist antibiotics, report into superbugs finds
Scientists have identified how deadly bacteria resist antibiotics at a molecular level for the first time, in a discovery that could have significant implications for the development of much-needed new drugs. According to a report published in Nature Scientific Communications this week, bacteria develop stronger cell membranes as they become resistant, repelling antibiotics and preventing effective treatment.
Philippines revokes Sanofi's product licence for dengue vaccine
The Philippines has permanently halted the sale, distribution and marketing of Sanofi’s dengue vaccine in the country after the French drug maker failed to meet the directives of regulators. Food and Drug Administration (FDA) Director General Nela Charade Puno said on Tuesday registration certificates for Dengvaxia products have been revoked because of Sanofi’s “brazen defiance” of the agency’s directives.

A rise in dengue cases among children in the wake of a measles outbreak in Central Visayas was reported by the Department of Health (DoH) on Sunday. Validated data from the DoH Epidemiology Bureau showed that dengue cases in the region from January 1 to 26 reached 1,657, higher than the 643 recorded in the same period in 2018 — a 158-percent increase.
Novel tools may help prevent tuberculosis reactivation
New diagnostic tools such as machine learning and precision medicine may help identify tuberculosis patients with the highest risk of reactivation of the disease, a study has found. Researchers from University of Michigan in the US showed that identifying multiple biomarkers can provide a more accurate diagnosis for patients.
Hyderabad: No H5N1 detected in humans in last 2 years
No new cases of the deadly H5N1 human infection have been detected in the world since February 2017, though a few new cases of the virus in birds were detected last week. Though cases of virus in poultry have dropped significantly, doctors warned that there is no room for complacency.
Novel tools such as Machine Learning and precision medicine could help treat patients with tuberculosis
New diagnostic tools such as Machine Learning and precision medicine could help identify tuberculosis patients with the highest risk of reactivation of the disease, say researchers. Researchers from the University of Michigan in the US have shown that identifying multiple biomarkers can provide a more accurate diagnosis for patients with Latent Tuberculosis Infection (LTBI).
Health Dept confirms dengue outbreak in Kuching

Persistence of antibiotic resistance genes in beef cattle backgrounding environment over two years after cessation of operation
Getahun E. Agga et al.,
Confined animal feeding operations can facilitate the spread of genes associated with antibiotic resistance. It is not known how cattle removal from beef cattle backgrounding operation affects the persistence of antibiotic resistance genes (ARGs) in the environment. We investigated the effect of cessation of beef cattle backgrounding operation on the persistence and distribution of ARGs in the beef cattle backgrounding environment.
