Prevention of inhalational anthrax after Bacillus anthracis spore exposure requires a prolonged course of antibiotic prophylaxis. In response to the 2001 anthrax attack in the United States, approximately 10,000 people were offered 60 days of antibiotic prophylaxis to prevent inhalational anthrax, but adherence to this regimen was poor. We sought to determine whether a short course of antibioti...

24 Scavenging of anthrax carcasses has long been hypothesized to play a critical role 25 in the production of the infectious spore-stage of Bacillus anthracis after host death, 26 though empirical studies assessing this are lacking. We compared B. anthracis spore 27 production, distribution and survival at naturally occurring anthrax herbivore carcasses 28 that were either experimentally caged ...

Anthrax is a worldwide zoonosis of herbivores, which is caused by the spore-forming bacteria Bacillus anthracis, and humans become infected when they are exposed to infected animals and their tissues or the organism directly. In this report, we present a 13-year-old boy who developed eyelid anthrax after contact with a sheep carcass during his summer holiday that resulted in eyelid anthrax and ...

Sera from Hartley guinea pigs vaccinated with a veterinary live spore anthrax vaccine were compared with sera from guinea pigs vaccinated with the human anthrax vaccine, which consists of aluminum hydroxide-adsorbed culture proteins of Bacillus anthracis V770-NP-1R. Sera from animals vaccinated with the spore vaccine recognized two major B. anthracis vegetative cell-associated proteins that wer...

We determined the genotypes of seven Bacillus anthracis strains that were recovered from nine anthrax outbreaks in North-East China from 2010 to 2014, and two approved vaccine strains that are currently in use in China. The causes of these cases were partly due to local farmers being unaware of the presence of anthrax, and butchers with open wounds having direct contact with anthrax-contaminate...

The significance of Bacillus anthracis as an agent of bioterrorism has been well established. An understanding of both the pathogenesis and the host response is required to elucidate approaches to more rapidly detect and effectively prevent or treat anthrax. Current vaccine strategies are focused primarily on production of antibodies against the protective antigen components of the anthrax toxi...

Anthrax is a severe, although rather rare, infectious disease that is caused by the Gram-positive, spore-forming bacterium Bacillus anthracis. The infectious form is the spore and the major virulence factors of the bacterium are its poly-γ-D-glutamic acid capsule and the tripartite anthrax toxin. The discovery of the anthrax toxin receptors in the early 2000s has allowed in-depth studies on the...

INTRODUCTION Anthrax is a febrile soil-born infectious disease that can affect all warm-blooded animals including man. Outbreaks of anthrax have been reported in northern region of Ghana but no concerted effort has been made to implement risk-based surveillance systems to document outbreaks so as to implement policies to address the disease. We generated predictive maps using soil pH, temperatu...

  Protection of animals immunized against Bacillus anthracis is usually demonstrated by challenging with an appropriate dose of a strain of Bacillus anthracis that is lethal to unvaccinated animals inoculated at the same time. In this study the protective efficacy in anthrax vaccine (34F2 sterne strain spore) was evaluated in sheep, goats and guinea pigs challenged with subcutaneous inoculation...

Unresolved scientific questions, remaining ten years after the anthrax attacks, three years after the FBI accused a dead man of perpetrating the 2001 anthrax attacks singlehandedly, and more than a year since they closed the case without further investigation, indictment or trial, are perpetuating serious concerns that the FBI may have accused the wrong person of carrying out the anthrax attack...
