We developed a model that enabled a back-calculation of the annual salmonellosis seroincidence from measurements of Salmonella antibodies and applied this model to 9677 serum samples collected from populations in 13 European countries. We found a 10-fold difference in the seroincidence, which was lowest in Sweden (0.06 infections per person-year), Finland (0.07), and Denmark (0.08) and highest ...

associated with excess mortality in the 243 patients included in the analysis, and the measured effect of ACSSuT was achieved by the inclusion of the nalidixic acid–resistant strains in this group. However, all deaths associated with nalidixic acid–resistant strains occurred in the 40 patients with Rtype ACSSuTNx (being DT104s), whereas none of the 43 patients infected with non-ACSSuT strains r...

Salmonella infection may be increased by alterations in the gastrointestinal tract, including decreased gastric acidity and chronic gastrointestinal disease. Leukocytosis was noted in 25% of patients. In fact, two thirds of the patients had a normal leukocyte count with immature leukocytes, which may be attributable to their relatively impaired cell-mediated immunity. The predominant organism i...

Foodborne bacterial diarrhea is an emerging health threat that is attributable to the increased consumption of fresh vegetables and fruits, the challenges associated with producing large quantities of inexpensive foods, the increasing importation of foods from developing regions, and the growing pattern of consumption of foods in public restaurants.1 Of the more than 5.2 million cases of bacter...

Special Issue Opportunistic infections occur with greater frequency or severity in patients with impaired host defenses. Growing numbers of HIV-infected persons, transplant recipients, and elderly persons are at increased risk. Alison Grant, London School of Hygiene and Tropical Medicine, discussed opportunistic infections due to HIV. In 1997, more than 30 million HIV-infected persons lived in ...

To the Editor: Human salmonellosis is a major public health problem of global concern. Salmonella enterica serotype Choleraesuis is a nontyphoid serotype; it has a narrow host range and is associated with a high proportion of invasive infections (50%–90% of isolates are from sterile sites [(1)]). In 2000, emergence of fluoroquinolone resistance in S. enterica ser. Choleraesuis was reported from...

Bael tree, (Aegle marmelos, FamilyRutaceae), is a sacred tree used for medicinal purpose. Some of the medicinal properties are astringent, antidiarreal, antidystentric, demulcent, stromachic, fever curing, insulin-promoter, antiinflammatory, cardio tonic and cures ophthalmic, urinary trouble, palpitation and many more. Most of these properties are believed to be due to presence of bioactive alk...

Typhoid fever is still an important public health problem in many developing countries especially in tropical parts of the world, as in Indonesia. This problem opens the way for a further study with the aim of finding an alternative serological test with a high degree of reliability for the detection of typhoid fever. Given the above mentioned purpose, a study on the reliability of a laboratory...

To the Editor: The clinical presentations of nontyphoidal Salmonella infection are protean, including gastroenteritis (most common), bacteremia, septic arthritis, osteomyelitis, and endovascular infection. (1). Despite the growing number of patients with invasive infection due to nontyphoid Salmonella, reports of thoracic empyema due to these organisms remain rare (2–6). We searched the compute...
