Investigation of Anthrax Associated with Intentional Exposure
October 19, 2001 / Vol. 50 / No. 41 889 Update: Investigation of Anthrax Associated with Intentional Exposure and Interim Public Health Guidelines, October 2001 893 Recognition of Illness Associated with the Intentional Release of a Biologic Agent 897 Weekly Update: West Nile Virus Activity — United States, October 10–16, 2001 Update: Investigation of Anthrax Associated with Intentional Exposure and Interim Public Health Guidelines, October 2001 On October 4, 2001, CDC and state and local public health authorities reported a case of inhalational anthrax in Florida (1 ). Additional cases of anthrax subsequently have been reported from Florida and New York City. This report updates the findings of these case investigations, which indicate that infections were caused by the intentional release of Bacillus anthracis. This report also includes interim guidelines for postexposure pro- phylaxis for prevention of inhalational anthrax and other information to assist epidemi- ologists, clinicians, and laboratorians responding to intentional anthrax exposures. For these investigations, a confirmed case of anthrax was defined as 1) a clinically compatible case of cutaneous, inhalational, or gastrointestinal illness* that is laboratory confirmed by isolation of B. anthracis from an affected tissue or site or 2) other labora- tory evidence of B. anthracis infection based on at least two supportive laboratory tests. A suspected case was defined as 1) a clinically compatible case of illness without isola- tion of B. anthracis and no alternative diagnosis, but with laboratory evidence of B. anthracis by one supportive laboratory test or 2) a clinically compatible case of an- thrax epidemiologically linked to a confirmed environmental exposure, but without cor- roborative laboratory evidence of B. -
Comparative Genome Analysis of 19 Ureaplasma Urealyticum and Ureaplasma Parvum Strains
Paralanov et al. BMC Microbiology 2012, 12:88 http://www.biomedcentral.com/1471-2180/12/88 RESEARCH ARTICLE Open Access Comparative genome analysis of 19 Ureaplasma urealyticum and Ureaplasma parvum strains Vanya Paralanov1, Jin Lu2, Lynn B Duffy2, Donna M Crabb2, Susmita Shrivastava1, Barbara A Methé1, Jason Inman1, Shibu Yooseph1, Li Xiao2, Gail H Cassell2, Ken B Waites2 and John I Glass1* Abstract Background: Ureaplasma urealyticum (UUR) and Ureaplasma parvum (UPA) are sexually transmitted bacteria among humans implicated in a variety of disease states including but not limited to: nongonococcal urethritis, infertility, adverse pregnancy outcomes, chorioamnionitis, and bronchopulmonary dysplasia in neonates. There are 10 distinct serotypes of UUR and 4 of UPA. Efforts to determine whether difference in pathogenic potential exists at the ureaplasma serovar level have been hampered by limitations of antibody-based typing methods, multiple cross-reactions and poor discriminating capacity in clinical samples containing two or more serovars. Results: We determined the genome sequences of the American Type Culture Collection (ATCC) type strains of all UUR and UPA serovars as well as four clinical isolates of UUR for which we were not able to determine serovar designation. UPA serovars had 0.75−0.78 Mbp genomes and UUR serovars were 0.84−0.95 Mbp. The original classification of ureaplasma isolates into distinct serovars was largely based on differences in the major ureaplasma surface antigen called the multiple banded antigen (MBA) and reactions of human and animal sera to the organisms. Whole genome analysis of the 14 serovars and the 4 clinical isolates showed the mba gene was part of a large superfamily, which is a phase variable gene system, and that some serovars have identical sets of mba genes. -
2001 Anthrax Letters
Chapter Five: 2001 Anthrax Letters Author’s Note: The analysis and comments regarding the communication efforts described in this case study are solely those of the authors; this analysis does not represent the official position of the FDA. This case was selected because it is one of the few major federal efforts to distribute medical countermeasures in response to an acute biological incident. These events occurred more than a decade ago and represent the early stages of US biosecurity preparedness and response; however, this incident serves as an excellent illustration of the types of communication challenges expected in these scenarios. Due in part to the extended time since these events and the limited accessibility of individual communications and messages, this case study does not provide a comprehensive assessment of all communication efforts. In contrast to the previous case studies in this casebook, the FDA’s role in the 2001 anthrax response was relatively small, and as such, this analysis focuses principally on the communication efforts of the CDC and state and local public health agencies. The 2001 anthrax attacks have been studied extensively, and the myriad of internal and external assessments led to numerous changes to response and communications policies and protocols. The authors intend to use this case study as a means of highlighting communication challenges strictly within the context of this incident, not to evaluate the success or merit of changes made as a result of these events. Abstract The dissemination of Bacillus anthracis via the US Postal Service (USPS) in 2001 represented a new public health threat, the first intentional exposure to anthrax in the United States. -

Periodontal diseases, some of the most common infectious diseases seen in humans, are characterized by gingival inflammation, as well as loss of connective tissue and bone from around the roots of the teeth, which leads to eventual tooth exfoliation. In the past decade, the as- sociation of periodontal diseases with the development of systemic diseases has received increas- ing attention. Although a number of studies have presented evidence of close relationships between periodontal and systemic diseases, the majority of findings are limited to epidemiological studies, while the etiological details remain unclear. Nevertheless, a variety of recent hypothesis driven investigations have compiled various results showing that periodontal infection and subsequent direct oral-hematogenous spread of bacteria are implicated inPROOF the development of various systemic diseases. Herein, we present current understanding in regard to the relationship between periodon- tal and systemic diseases, including cardiovascular diseases, preterm delivery of low birth weight, diabetes mellitus, respiratory diseases, and osteoporosis. Keywords: periodontal disease, diabetes mellitus, cardiovascular disease, preterm delivery, Porphyromonas gingivalis, oral bacteria 1. Introduction detected in heart valve lesions and atheromatous plaque (5, 6), amniotic fluid of pregnant women with threatened Epidemiological and interventional studies of humans premature labor (11), and placentas from cases of preterm have revealed close associations between periodontal delivery (12, 13). -

Bioterrorism, Biological Weapons and Anthrax
Bioterrorism, Biological Weapons and Anthrax Part IV Written by Arthur H. Garrison Criminal Justice Planning Coordinator Delaware Criminal Justice Council Bioterrorism and biological weapons The use of bio-terrorism and bio-warfare dates back to 6th century when the Assyrians poisoned the well water of their enemies. The goal of using biological weapons is to cause massive sickness or death in the intended target. Bioterrorism and biological weapons The U.S. took the threat of biological weapons attack seriously after Gulf War. Anthrax vaccinations of U.S. troops Investigating Iraq and its biological weapons capacity The Soviet Union manufactured various types of biological weapons during the 1980’s • To be used after a nuclear exchange • Manufacturing new biological weapons – Gene engineering – creating new types of viruses/bacteria • Contagious viruses – Ebola, Marburg (Filoviruses) - Hemorrhagic fever diseases (vascular system dissolves) – Smallpox The spread of biological weapons after the fall of the Soviet Union •Material • Knowledge and expertise •Equipment Bioterrorism and biological weapons There are two basic categories of biological warfare agents. Microorganisms • living organic germs, such as anthrax (bacillus anthrax). –Bacteria –Viruses Toxins • By-products of living organisms (natural poisons) such as botulism (botulinum toxin) which is a by- product of growing the microorganism clostridium botulinum Bioterrorism and biological weapons The U.S. was a leader in the early research on biological weapons Research on making -

However, GAO was identified as the Ames strain. found that the FBI lacked a comprehensive approach—or framework—that could Subsequently, FBI contractors have ensured standardization of the testing process. As a result, each of the developed and validated several contractors developed their tests differently, and one contractor did not conduct genetic tests to analyze B. anthracis verification testing, a key step in determining whether a test will meet a user’s samples for the presence of certain requirements, such as for sensitivity or accuracy. Also, GAO found that the genetic mutations. The FBI had contractors did not develop the level of statistical confidence for interpreting the previously collected and maintained testing results for the validation tests they performed.
