In diarrhea caused by invasive pathogens such as Salmonella, Shigella, and Campylobacter, the use of such agents has generally been strongly discouraged, though evidence is lacking that they are harmful when administered in combination with antibiotics in Clostridium difficile cases.
Hektoen enteric agar (also abbreviated as HE) is a selective agar used in microbiology, commonly used to recover Salmonella and Shigella species
Her work has investigated bacterial infections, such as Shigella, and Listeria.
Mark Frederick Boyd (May 21, 1889-Michigan, USA-1968) was an American bacteriologist who discovered a shigella species known as shigella boydii.
The most commonly observed signs associated with Shigella dysentery include colitis, malnutrition, rectal prolapse, tenesmus, reactive arthritis, and CNS problems.
If diarrhea is present, cultures of stool should be examined for enteropathogens (i.e., Salmonella, Shigella, Campylobacter, and Yersinia).
