Veterinary assistants and laboratory animal caretakers look after animals in laboratories, animal hospitals, and clinics. They care for the animals by performing routine tasks under the supervision of scientists, veterinarians, and veterinary technologists and technicians.
Dysentery is an inflammation of the intestine causing diarrhea with blood. Other symptoms may include fever, abdominal pain, and rectal tenesmus (a feeling of incomplete defecation).
There are two main types of dysentery: bacillary and amoebic. Of the two, bacillary is more common, and it involves bacteria from the Shigella genus entering through the mouth and multiplying in the bowel.
