C AUSES Bacteria Bacillus anthracis

S CIENTIFIC CLASSIFICATION Kingdom: Bacteria Bacteria Phylum: Firmicutes Firmicutes Class: Bacilli Bacilli Order: Bacillales Bacillales Family: Bacillaceae Bacillaceae Genus: Bacillus Bacillus Species: B. anthracis

S TRAINS ( TYPES ) Cutaneous (skin) Inhalation (lungs) Gastrointestinal (digestive)

Anthrax toxin is made up of three proteins: protective antigen (PA), edema factor (EF), and lethal factor (LF). PA binds to specific cell receptors, and following proteolytic activation it forms a membrane channel that mediates entry of EF and LF into the cell. EF is an adenylyl cyclase; with PA it forms a toxin known as edema toxin. LF plus PA form lethal toxin, which is a major virulence factor and cause of death in infected animals. ANTHRAX TOXIN

Center for Food Security and Public Health, Iowa State University, 2008 H UMAN T RANSMISSION Industry Tanneries Textile mills Wool sorters Bone processors Slaughterhouses
11
Center for Food Security and Public Health, Iowa State University, 2008 H UMAN T RANSMISSION Cutaneous Contact with infected tissues, wool, hide, soil Biting flies Inhalational Tanning hides, processing wool or bone Gastrointestinal Undercooked meat
12
T HROUGH A NIMALS Humans can become infected after handling infected animals Breathing anthrax spores from infected products (like wool) Eating undercooked meat from infected animals (Undercooked meat)
13
H OW IS IT TRANSMUTABLE ? A S A BIOLOGICAL WEAPON Anthrax spores can be distributed Ex. USA 2001, anthrax spores spread through postal system via letters containing spores
14
A NTHRAX SPORES
15
W HO GETS IT ? Animals primarily Common in… South & Central America Southern/Eastern Europe Asia Africa Middle East
17
I NCUBATION P ERIOD symptoms appear within 7 days of initial contact For inhalation anthrax, anywhere from a week to 60 days
18
S TRAINS ( TYPES ) Cutaneous (skin) Inhalation (lungs) Gastrointestinal (digestive)
19
CUTANEOUS ANTHRAX Raised itchy bump (resembles incest bite) 1-2 days, develops into a vesicle (cyst) Develops into painless ulcer (1-3 cm diameter) Ulcer has black center Swelling of surrounding tissues Swelling of adjacent lymph glands
21
G ASTROINTESTINAL A NTHRAX Initial signs: nausea Loss of appetite Vomiting blood Sever diarrhea Lesions & soreness in throat Difficulty swallowing Swelling of neck &lymph glands 50% of all patients develop meningitis
23
I NHALATION ANTHRAX Flu/cold like symptoms Cough Chest discomfort Shortness of breath Tiredness & muscle aches
24
Meditational widening with inhalation anthrax
25
D IAGNOSIS Bacterial cultures Measuring specific antibodies in blood Positive cultures are unlikely after antibiotic treatment has been started
26
Anthrax is acute (of abrupt onset, of short duration, rapidly progressing & in need of urgent care) People can’t become immune to anthrax Can get anthrax multiple times
27
W HAT PARTS OF THE BODY ARE AFFECTED ? In cutaneous anthrax: Skin, surrounding tissues & lymph glands In gastrointestinal anthrax: Digestive system, neck & lymph glands In inhalation anthrax: Respiratory & immune system
28
T REATMENST Anthrax vaccine Avoiding contact w/ animals Don’t eat improperly slaughtered/cooked meat
29
F URTHER TREATMENT Prevention after exposure: Antibiotic & vaccine combo Treatment after infection: 60 day course of antibiotics Success depends on type of anthrax & how soon treatment was started Anthrax is terminal if left untreated
