What is salmonella typhosn

Typhoid is  an enteric fever, which relates  to acute infection of  short duration. It is   caused by bacteria called Salmonella typhosn about which you may recall studying  ' in the Food Microbiology and Safety Course. The mode of  spread  of  this infection is through the fecal-oral route. The source of infection  is  the drinking water, milk and  food contaminated  by  intestinal contents (through feces and urine) of the patients or "carriers" or by  flies which transmit the disease.  It may affect  all  age groups  but  is  commonly observed  in children.  The incidence and magnitude of  typhoid fever has greatly reduced  in the present context due to improved sanitation and vaccines and effective drugs available.
