Study provides new insights into how the human immune system protects against Ebola infections

Two types of human antibodies that target different parts of the Ebola virus synergize their antiviral effects by inhibiting different steps of infection, according to a study published August 23 in the open-access journal PLOS Pathogens by Philipp Ilinykh and colleagues from the University of Texas Medical Branch, Vanderbilt University, and Ragon Institute.

			Rapid urbanization makes Central Africa more vulnerable to infectious disease outbreaks The Central Africa region is experiencing rapid urbanization and economic growth, and infrastructure development. These changes, while generally positive and welcome, also make the region more vulnerable to explosive infectious disease outbreaks, according to an international group of scientists.

			Study sheds light on how cholera became a human pathogen Scientists think they may have discovered how V. cholerae became a human pathogen, through its ability to interact with amoebae in aquatic environments.

	Most parents aren't able to recognize meningitis until it's too late New research commissioned by GSK has shown that the majority of parents incorrectly think that a rash or stiff neck are the first signs of meningitis.

	Researchers gain new insight into how malaria parasites hijack human red blood cells Researchers at Iowa State University have gained new insight into how the parasitic protozoa that cause malaria hijack human red blood cells, a development with the potential to lead to new ways to treat the disease.

	Loss of treated bed nets between campaigns may have greater impact on malaria transmission A new study published in the Lancet journal EClinicalMedicine suggests that more mosquito nets are likely needed between mass campaigns to keep malaria cases in check.

	Researchers report how Zika proteins hijack host cells Most people infected with Zika never show symptoms. But the virus sometimes causes severe disability -- from microcephaly in babies to weakness or partial paralysis in adults -- and there is no treatment.

	Researchers identify Zika virus proteins with potential to affect brain development In healthy individuals, the Zika virus causes flu-like symptoms. If a pregnant woman becomes infected, the unborn child can suffer from severe brain abnormalities as a result of mechanisms that have not yet been explained.

	Grim updates on Ebola outbreak in Congo According to the health ministry, there have been five new cases of Ebola and five deaths from haemmorhagic fever. Ebola cases now sum up at 96 (5 new cases) from the town of Mabalako-Mangina. A total of 69 are confirmed. 55 people have died.

	Effective vaccines for world's most prevalent infectious diseases are missing from pipeline Many of the vaccines critically needed to fight some of the world's most prevalent infectious diseases are not likely to be developed, a new analysis of current candidates in the research and development pipeline has found.

	Researchers unravel how Zika virus manipulates the human immune system Macrophages are immune cells that are supposed to protect the body from infection by viruses and bacteria. Yet Zika virus preferentially infects these cells. Researchers at University of California San Diego School of Medicine have now unraveled how the virus shuts down the genes that make macrophages function as immune cells.

	Hepatitis B and Hepatitis D Hepatitis B is a life-threatening liver infection that is caused by the hepatitis B virus, whereas, hepatitis D infection only occurs in people who are infected with the hepatitis B virus. It replicates autonomously within hepatocytes, but requires hepatitis B surface antigen for proliferation.
