An international team of scientists, led by researchers at University of California, San Diego School of Medicine and the J. Craig Venter Institute (JCVI), have created the first comprehensive, cross-species genomic comparison of all 20 known species of Leptospira, a bacterial genus that can cause disease and death in livestock and other domesticated mammals, wildlife and humans.

A three-dimensional 'map' of a critical protein that malaria parasites use to invade human red blood cells could lead to a vaccine countering the most widespread species of the parasite. The discovery also raises the prospect of a vaccine that could target both the most prevalent and the most deadly malaria parasites that infect humans, a significant development for the future of malaria prevention.

With the outbreak of viruses like Zika, chikungunya, and dengue on the rise, public health officials are desperate to stop transmission. Virginia Tech experts explore one way -- through the genetic engineering of mosquitoes to maleness -- in the Feb. 17 issue of the journal Trends in Parasitology.

At the two hospitals where I work, the sterile processing departments (SPDs) are located in the basement and near the morgue. To think that people are literally dying to be closer to the SPD is a unique feature that not just any hospital department can claim!

Q: Are we allowed to use latex gloves in the decontamination area?  Is there any documentation in AAMI or OSHA that dictates the use of latex gloves in the decontamination area? Secondly, are we allowed to wear gloves in the sterile prep area while putting together trays?A:  According to the Occupational Safety & Health Administrations’ Blood Borne Pathogen Ruling (2001), “Personal protective equipment (i) Provision. When there is occupational exposure, the employer shall provide, at no cost to the employee, appropriate personal protective equipment such as, but not limited to, gloves, gowns, laboratory coats, face shields or masks and eye protection, and mouthpieces, resuscitation bags, pocket masks, or other ventilation devices. Personal protective equipment will be considered “appropriate” only if it does not permit blood or other potentially infectious materials to pass through or reach the employee’s work clothes, street clothes, undergarments, skin, eyes, mouth, or other mucous membranes under normal conditions of use and for the duration of time that the protective equipment will be used. Accessibility. The employer shall ensure that appropriate personal protective equipment in the appropriate sizes is readily accessible at the work site or is issued to employees. Hypoallergenic gloves, glove liners, powderless gloves, or other similar alternatives shall be readily accessible to those employees who are allergic to the gloves normally provided.”

Bacteria have evolved thousands of clever tactics for invading our bodies while evading our natural defenses. Now, UNC School of Medicine scientists studying one of the world’s most virulent pathogens and a separate very common bacterium have discovered a new way that some bacteria can spread rapidly throughout the body – by hitchhiking on our own immune cells.
