Some of the more common nontyphoidal species are: Worldwide over 20 million cases of typhoid fever occur each year, mostly in the developing world, Approximately 1800 cases of typhoid fever occur in the United States annually, mostly in travelers, From 1.0 to 1.2 million cases of nontyphoidal illness occur in the United States each year, causing about 19,000 hospitalizations and 450 deaths, Tens of millions of nontyphoidal illness occur worldwide, causing over 100,000 deaths each year, Disease occurs from ingestion of bacteria, usually in food or water, eggs, milk, meat, poultry, Vegetables contaminated with animal feces are commonly implicated, Food borne outbreaks, often associated with less than sanitary conditions, are common sources of disease, However, in the United States approximately 60% of cases occur sporadically, Fecal oral transmission may occur; disease after contact with infected animals is another source, Salmonellosis is a common cause of traveler diarrhea, All serotypes at least in theory may cause human disease, Serotypes may or may not be host specific, When serotypes specific to other species infect humans.

Author summary With an estimated 20 million typhoid cases and an even higher number of non-typhoid cases the health burden caused by salmonellosis is huge. together with secondary bacteremia and peritonitis (, Perforation is four times more common in males than females (, Nontyphoidal salmonellosis traditionally has been diagnosed by stool culture although many patients do not seek medical attention, Recently a PCR based assay has been introduced that, in addition to, Serotyping is done to characterize disease outbreaks, Typhoid fever is diagnosed by blood or stool culture, In the developing world where laboratory facilities may not be readily available, disease may be treated empirically, Bone marrow culture is the most sensitive test available, as it remains positive even after 5 days of antibiotic therapy (, CBC shows leukopenia and thrombocytopenia, Cultures can be from blood, stool, urine, rose spots, the blood mononuclear cell platelet fraction, bone marrow, gastric or intestinal secretions, Children also have a higher incidence of positive stool cultures than adults (60% versus 27%), The duodenal string test is useful for sampling the upper GI tract (, Most common colonoscopic finding is multiple variably sized punched out ulcers with slightly elevated margins, Also edematous hyperemic mucosal patches with hemorrhagic spots or shallow erosions, Antibiotic therapy is usually efficacious in these patients, although antibiotic resistance is a growing problem, Prompt initiation of antibiotic therapy greatly improves patient outcome; although again, antibiotic resistance is a growing problem, Infant with large bowel obstruction as presentation of salmonella enterocolitis (, 57 year old man with endovascular infection with, 62 year old man with toxic megacolon due to, Family outbreaks of nontyphoidal salmonellosis (, 18 year old man with acute scrotal ulcers in typhoid fever (, 30 year old man with gastrointestinal bleeding from paratyphoid A fever (, Only requires supportive care, particularly hydration, Antibiotics are indicated for severe disease and vulnerable patients, Ceftriaxone and ciprofloxacin are currently recommended by the CDC, Antibiotic resistance is a growing problem, Prolonged course of antimicrobials and supportive care with transfusions, Antibiotic therapy for typhoid fever is obligatory and should not be delayed for confirmatory laboratory testing, Ceftriaxone and ciprofloxacin are currently recommended by the CDC (, Third generation fluoroquinolones are also recommended but resistance has been reported, In the past, chloramphenicol, trimethoprim-sulfamethoxazole, cephalosporins and first generation fluoroquinolones were used but antibiotic resistance developed, Surgery may be necessary for intestinal perforation or gallbladder disease, Selective angiography and platinum coil embolization is used for severe, life threatening lower gastrointestinal hemorrhage, Ensure food is properly cooked and hot when served, Avoid raw milk and products made from raw milk, Use disinfecting tablets for water unless its purity is certain, Wash hands thoroughly with soap and water after contact with pets or farm animals and after using the toilet, Wash fruits and vegetables thoroughly and if possible, peel fruits and vegetables unless optimal sanitary practices are known to have taken place, Do not work if have fever, diarrhea, vomiting or infected skin lesions, Colonoscopy in patients with mild nontyphoidal salmonellosis shows nonspecific findings including edema and petechial hemorrhage; more severe disease is associated with friability and ulceration, Typhoid fever causes marked enlargement of Peyer patches and lymphoid tissue in the appendix and ascending colon leading to mucosal elevation along the axis of the ileum, Small gray, soft nodules (typhoid nodules) may be present in the liver, There is splenomegaly and lymphadenopathy, Nontyphoidal salmonellosis is rarely biopsied, The findings are a non-specific acute self limited colitis, The crypt architecture is maintained, there are increased mixed inflammatory cells within the lamina propria in a patchy distribution with foci of cryptitis and possible crypt abscesses, Long standing cases may demonstrate architectural distortion raising the spectre of idiopathic inflammatory bowel disease, Knowledge of culture results is necessary to render a specific diagnosis, The spleen and lymph nodes show sinus histiocytosis that distorts the normal architecture, Typhoid nodules in the liver show aggregates of histiocytes with necrotic debris, Typhoid nodules may also be found in bone marrow and lymph nodes, The differential diagnosis of nontyphoidal salmonellosis includes other enteric pathogens that cause acute self limited colitis including, Long standing cases may mimic idiopathic inflammatory bowel disease.
