Bacon introduces bill to improve U.S. military biodefense readiness

H.R. 5482 would require the plan be submitted to Congress addressing specific steps that the U.S. Department of Defense (DOD) would take to improve detection, diagnostics and patient care; to expedite research into military medical countermeasures; and to establish military infectious disease response teams, according to a summary provided by Rep. Bacon’s staff, which added that current geopolitical risks call for DOD to have a comprehensive “all-hazards” approach to biodefense. Ripon Advance

The race to find the next pandemic—before it finds us

The mystery epidemic had spread to four farms and was killing the piglets, almost 25,000 of them. By the time the outbreak burned out in May, it seemed to be something no one had seen before. They were right: The cause of the piglets’ illness, identified by the US-based EcoHealth Alliance and published in Nature last week, was a totally new virus. Wired

The plague: An overview and hot topics

Plague is one of the re-emerging diseases according to the WHO and Madagascar suffered in 2017 the most important plague epidemic of the 21st century with more than 2000 cases and 200 deaths. Peru and the Democratic Republic of Congo are also considered endemic areas. PubMed

Utilization of Francisella tularensis LVS to generate a plague/ tularemia vaccine

Researchers generated a construct in which the coding region for Tul4 (an immunodominant protein of F. tularensis) is linked to OmpA (a protective antigen of Y. pestis) under the control of a robust F. tularensis promoter.  This construct was constructed in E. coli and was subsequently mobilized to F. tularensis LVS (Live Vaccine Strain).

Novel immunotherapy of Brucellosis in cows monitored non-invasively through a specific biomarker

Brucellosis is an important zoonotic disease causing huge economic losses worldwide. This is the first report on minimally invasive monitoring of the efficacy of antibacterial therapy employing plasma RNA specific for live bacteria as a biomarker as well as on the use of RB51 phage lysate for successful immunotherapy of Brucellosis in cattle.PLOS Neglected Tropical Diseases

Immunogenicity and safety of production lots of the non-replicating smallpox vaccine MVA

Modified Vaccinia Ankara (MVA) is a live, viral vaccine under advanced development as a non-replicating smallpox vaccine. A randomized, double-blind, placebo-controlled phase III clinical trial was conducted to demonstrate the humoral immunogenic equivalence of three consecutively manufactured MVA production lots, and to confirm the safety and tolerability of MVA focusing on cardiac readouts. PLOS One

Anthrax: A disease of herbivores (and a dangerous bioweapon)

For the most part, anthrax is a zoonotic infection, and humans are incidental hosts. Human infection is typically linked to infection of herbivores (eg, cattle, horses, sheep) from the soil where they graze. Spores of Bacillus anthracis are prevalent throughout the world and, depending on environmental conditions, can survive in soil for months to years. Healio


FDA investigating multistate outbreak of E. coli O157:H7 linked to chopped romaine

Illnesses likely linked to chopped romaine lettuce sourced from the winter growing areas in Yuma, Arizona. 35 people in 11 states have become ill. Most people reported eating a salad at a restaurant, and romaine lettuce was the only common ingredient identified among the salads eaten. FDA

Doctors battle drug-resistant typhoid outbreak

The first known epidemic of extensively drug-resistant typhoid is spreading through Pakistan, infecting at least 850 people in 14 districts since 2016, according to the National Institute of Health Islamabad. The typhoid strain, resistant to five types of antibiotics, is expected to disseminate globally, replacing weaker strains where they are endemic. NY Times

Flesh-eating ulcer spreading rapidly in Australia

A severe tissue-destroying ulcer once rare in Australia is rapidly spreading and is now at epidemic proportions in regions of Victoria, prompting infectious diseases experts to call for urgent research into how it is contracted and spread. Guardian

‘Mad camel’ disease? New prion infection causes alarm
