1. Bacteria that escape predation : waterborne pathogens and their relatives
Abstract : The hidden presence of opportunistic bacterial pathogens in the environment evokes concerns about emerging diseases, especially in the light of climate change. The co-evolution of bacteria and their predators (protozoa) has led to bacterial defence strategies of which some contribute to the ability of bacteria to cause disease. READ MORE

2. Leukocyte responses to pathogens : integrins, membrane rafts and nitric oxide
Abstract : During microbial invasion, leukocytes of the innate immunity are rapidly recruited to the site of infection where they internalize (phagocytose), kill and digest the invaders. To aid this process, leukocytes express surface receptors such as Toll-like receptors, β2-integrins and Fc-receptors. READ MORE

3. Mucosal immunity in the respiratory tract : The role of IgA in protection against intracellular pathogens
Abstract : The lungs and upper airways are mucosal surfaces that are common site for infection with an enormous variety of inhaled pathogens. Therefore, induction of immune responses in the respiratory tract is crucial for protection against respiratory diseases. One of the pathogens infecting the host via the respiratory tract is Mycobacterium Tuberculosis. READ MORE

4. Pathogen entry mechanisms and endocytic responses to plasma membrane damage
Abstract : Endocytosis is a fundamental cellular process by which cells transport material from the outside to the inside of the cell through the formation of membrane invaginations that bud off from the plasma membrane. This process is important for nutrient uptake, regulating cell surface receptors and the overall plasma membrane composition. READ MORE

5. Microbial risk assessment and its implications for risk management in urban water systems
Abstract : Infectious disease can be transmitted via various environmental pathways, many of which are incorporated into our water and wastewater systems. Quantitative microbial risk assessment (QMRA) can be a valuable tool in identifying hazard exposure pathways and estimating their associated health impacts. READ MORE
