How does Shigella grow?
Shigella sonnei is the major cause of shigellosis from food. Virulent Shigella organisms attach to and penetrate the epithelial cells of the intestine. After invasion, they multiply and spread to the epithelial cells.

How is shigella treated?
Shigella can be resistant to some antibiotics, so a doctor will perform a stool test to see which antibiotics may help. Antibiotics commonly used to treat Shigella are ampicillin, trimethoprim/sulfamethoxazole (Bactrim, Septra), ceftriaxone (Rocephin), or ciprofloxacin. Precautions can prevent the spread of Shigella.

CHARACTERISTICS: Shigella spp., of the Enterobacteriaceae family, are gram-negative rod-shaped pathogenic bacteria (1). They are non-motile, non-encapsulated, and facultative anaerobes that do not ferment lactose, or do so slowly.
Why do I need two doses of Shingrix?
Two doses of Shingrix provides strong protection against shingles and postherpetic neuralgia (PHN), the most common complication of shingles. In adults 50 to 69 years old who got two doses, Shingrix was 97% effective in preventing shingles; among adults 70 years and older, Shingrix was 91% effective.
Are both doses of Shingrix the same?
Shingrix is given as an injection into the muscle (intramuscular), typically in your upper arm. You’ll receive two separate doses of the vaccine. Each dose contains 0.5 mL of vaccine solution.
