Having been involved in microbiology for so long it’s sometimes difficult to see the progress we are making. When I started out as a microbiologist in the 1970s the impact of molecular biology on microbiology was overwhelming, even if it took … Continue reading
The first available dengue vaccine, CYD-TDV (Dengvaxia), is estimated to reduce the burden of dengue and be potentially cost effective in settings where infections with dengue are common. The Long-Term Safety, Public Health Impact, and Cost- Effectiveness of Routine … Continue reading
New research from my colleagues at the University of Leicester shows that “salad juice” from damaged leaved in bagged salads can stimulate the growth of Salmonella, even at refrigerator temperatures. Although this research did not look for evidence of Salmonella … Continue reading
Some mutations that enable drug resistance in the malaria-causing parasite Plasmodium falciparum may also help it grow. Plasmodium falciparum is a single-celled parasite that infects the human bloodstream and causes the most severe form of malaria. Some strains of P. … Continue reading
Bacteria behave differently in space, as indicated by reports of reduced lag phase, higher final cell counts, enhanced biofilm formation, increased virulence, and reduced susceptibility to antibiotics. These phenomena are theorized, at least in part, to result from reduced mass … Continue reading
This week I’ve been talking to first year students about cell biology, discussing how much the environment of the cell varies from one site to another within the cell. Viruses “know” this and much virus replication is localized at particular … Continue reading
Every year more than 350 million people in over 120 countries contact dengue fever, which can cause symptoms ranging from aching muscles and a skin rash to life-threatening haemorrhagic fever. Researchers have struggled to create effective vaccines against dengue virus, … Continue reading
Human African trypanosomiasis – sleeping sickness – is a potentially fatal disease, which currently affects ~3,500 people in sub-Saharan Africa. The disease is caused by parasites called African trypanosomes and is spread by tsetse flies. Controlling these biting insects, combined … Continue reading
