AP Biology- Bacteria (pathogens)

W/ Pathogens

Pathogen: Bacillus Anthracis

Effects: Animals, including processed skins

Epidemiology: Bacterial infection, transmitted through contact or ingestion, rare, may be fatal

Anthrax

Pathogen: Clostridium Botulinum

Effects: Improperly prepared food

Epidemiology: Contracted through ingestion or contact with wound, produces toxic poison, can be fatal

Botulism

Pathogen: Chlamydia Trachomatis

Effects: Humans, STD

Epidemiology: Urogenital infections with possible spread to eyes and respiratory tract, increasingly more common

Chlamydia

Pathogen: Vibrio Cholerea

Effects: Human feces, plankton

Epidemiology: Severe diarrhea that can lead to death by dehydration, 50% mortality rate, major killer in places with poor sanitation, after earthquake 180,000 people were effected in 7 days

Cholera

Pathogen: Streptococcus mutans/sobrinus

Effects: Humans

Epidemiology: A dense collection of this bacteria on the teeth leads to secretion of acids that destroy tooth enamal

Dental Caries

Pathogen: Corynebacterium Diphtheriae

Effects: Humans

Epidemiology: inflammation and lesions of respiratory mucous membranes, spreads through respiratory droplets, vaccine available

Diphtheria

Pathogen: Neisseria Gonnorrhoeae

Effects: Humans only

Epidemiology: STD, increasing worldwide, usually not fatal

Gonorrhea

Pathogen: Mycobacterium Leprae

Effects: Humans, feral armodillos

Epidemiology: Infection of the skin; 10-12 million affected, especially in southeast asia, spread through contact with affected individuals

Hansen Disease (leprosy)

Pathogen: Borrellia Burgdorferi

Effects: Ticks, deer, small rodents

Epidemiology: Spreads through bite of infected tick, lesions is followed by malaise, fever, fatigue, pain, stiff neck, and headache

Lyme Disease

Pathogen: Heliobacter Pylori

Effects: Humans

Epidemiology: Originally thought to be caused by stress or diet, now found to be caused by this bacterium, can be treated by antibiotics

Peptic Ulcers

Pathogen: Yersinia Pestis

Effects: Fleas of wild rodents (rats and squirrels)

Epidemiology: Killed ¼ of the population of Europe in the 14th century, is now an edenmic in wild rodents In western U.S. today

Plague

Pathogen: Streptococcus, Mycoplasma, Chlamydia, Haemophilus

Effects: Humans

Epidemiology: Infection of the lungs, often fatal without treatment, vaccine available

Pnuemonia

Pathogen: Mycobacterium Tuberculosis

Effects: Humans

Epidemiology: Bacterial infection of the lungs, lymph, and meninges

Tuberculosis

Pathogen: Salmonella Typhi

Effects: Humans

Epidemiology: Bacterial disease worldwide, spreads through contaminated water or foods, vaccines available for travelers

Typhoid Fever

Pathogen: Rickettsia Typhi

Effects: Lice, rat fleas, humans

Epidemiology: Historically a major killer, transmitted human to human through the bite of infected lice and fleas, mortality rate of 80%

Typhus
