Bioterrorism agents
Four pathogens that are potential biowarfare and bioterrorism agents
B. Anthracis
C. Botulinum
V. Major
Y. Pestis
It is caused by B. Anthracis
Anthrax
A spore forming, gram positive bacillus
B. Anthracis
Three forms of anthrax

Bubonic plague
What category are the etiologic agents of anthrax, botulism, small pox, and plague
Category A
Pose the greatest possible threat for a bad effect on public health
Category A agents
May spread acrooss a large area and need great deal of planning
Category A agents
A moderate to high protential for large scale dessimination
Category B agents
Currently not believed to present a high bioterrorism risk to, future threats
Category C
Sanitation Code of the Phillipines
PD 856
The Philippine Act of 2004
Republic Act No. 9275
Aims to protect the country’s water bodies from pollution from land-based sources
RA 9275
Water is considered potable (safe to drink) of it contains
1 coliforms or less 100 ml of water
It contains mainly water, faecal materials, garbage and bacteria from the drains of houses and other buildings
Raw sewage
In the sewage disposal plant, large debris is first filtered out, skimmers remove floating grease and oil
Primary sewage treatment
The liquid then undergoes second treatment, which includes aeration or trickling filtration
Secondary sewage treatment
In some desert cities, where water is short supply, the effluent water from the sewage disposal plant is further treated
Tertiary sewage treatment
