Using biologics during pregnancy may not raise infant's risk for opportunistic infections

Using a biologic therapy to manage rheumatoid arthritis may not significantly increase an infant's risk for developing opportunistic infections like pneumonia, meningitis, and tuberculosis, according to new research findings presented this week at the 2017 ACR/ARHP Annual Meeting in San Diego.

Study sheds light on virulence strategy of intracellular bacteria that cause legionellosis

Intracellular pathogens adopt various strategies to circumvent the defences of the host cell and to proliferate intracellularly. One specific strategy is to target host organelles like the mitochondria. Mitochondria are well-defined cytoplasmic organelles, which take part in a variety of cellular metabolic functions.

Case of Legionnaires’ disease in the city sparks alerts

A New York Police Department officer has contracted Legionnaires’ disease leading to a spate of investigations by the health officials as to its source and potential capacity for spread. The officer however is at present on their way to recovery at a hospital located outside the city said health officials. Legionnaire’s disease is a form of pneumonia that can become life threatening.

New biophotonic light sensor can detect Legionella bacteria in minutes

Outbreaks of Legionnaire’s Disease, a respiratory infection that can cause pneumonia, and in severe cases organ failure or septic shock, are more common than we might think. With anyone being susceptible, more than 100 cases are reported each week both in America and in Europe, with a fatality rate of around 10%.

Bacteria lurking in dental water lines

Bacteria lurking in the water lines at the dentist's office are tougher than we thought, according to a new paper published in Water Research. The study reveals that the disinfectants recommended by companies that manufacture the water lines don't actually shift all the bacteria in the lines, which means they're never completely clean.
