S. Enterotoxicosis methodology

Binds to host receptor cells

S. Enterotoxicosis transmission

People are carriers contaminate foods, like potato salad

S. Enterotoxicosis treatment/prevention

It's self-limiting, symptoms resolve on their own after 24hrs

Maintain food at proper temperatures and keep good kitchen hygiene

Botulism treatment /prevention

Supportive therapy to allow nerve endings to regenerate

Cook foods in a pressure cooker and never eat from damaged cans

Heliobacter causative bacteria

Heliobacter pylori

Heliobacter symptoms

Peptic ulcers, nausea, abdominal pain increase on an empty stomach, burping

Heliobacter methodology

Destroys the mucosal surface of the stomach and its cells

Unknown, although maybe direct transmission of saliva

Heliobacter treatment /prevention

Antimicrobial therapy and acid blockers

No effective method of prevention

Salmonellosis causative bacteria

Salmonella enterica enteritidis

Salmonella symptoms

Mild diarrhea, fever, nausea, abdominal cramps

Salmonella methodology

Binds to M cells and enters them to get to the blood and then colonize in the liver and spleen

Salmonella transmission

From contaminated meats, cross contamination, pets, fruits or vegetables

Salmonella treatment /prevention

Oral or IV rehydration

Fully cook your meat, wash hands often, prevent cross contamination

Typhoid fever causative bacteria

S. Typhi

Good hygiene, getting tested, avoiding sick individuals

Cholera causative bacteria

Vibrio cholera

Cholera symptoms

Dry mucous membrane, low blood pressure, muscle cramps, death

Cholera methodology

In the small intestine they secrete cholera toxin, which bind and enter host cells and force chloride ions out if the cell, flooding the intestine with water

Campylobacter methodology

Infects macrophages and goes to other areas of the body

Campylobacter symptoms

temporary bilateral paralysis, severe abdominal cramping, dysentery like symptoms

Campylobacter transmission

Primarily lives in chickens, food borne illness

Campylobacter treatment /prevention

Self limiting, antibiotics can be administered

C. Difficile symptoms

toxic megacolon, colon rupture, horrible smell, swollen abdomen

C. Difficile methodology

Produces Cytotoxin, CDT, and kills cells for new areas to colonize

C. Difficile transmission

Spores usually from a medical setting

C. Difficile treatment /prevention

Remove patient from the first antibiotic and put them on one that targets the organism, fecal transplant

Don't overuse antibiotics, isolate patients
