Four strains of Salmonella typhimurium avirulent for mice were found to be capable of acting as gene acceptors in transduction experiments. An attempt was made to transduce virulence to three strains, using a typical mouse-virulent strain of S. typhimurium as donor. Two of the strains which are adenine-dependent were successfully made virulent by transduction and simultaneously became adeninein...

About 600 compounds were screened as possible carbon or nitrogen sources for Salmonella typhimurium LT-2. About 100 utilizable compounds were found.

Murine monoclonal antibodies to target Salmonella typhimurium flagellin and lipopolysaccharide (LPS) were prepared and characterized. For the immunological detection of S. typhimurium, different pairs of monoclonal antibodies (MAbs) were tested in a sandwich enzyme linked immunosorbent assay (ELISA) format. After comparison, a sandwich ELISA and immunochromatographic strip based on LPS MAbs was...

Peritoneal cells obtained from mice immunized 15 or 30 days previously with (i) 0.1 LD(50) of attenuated Salmonella typhimurium (RIA), (ii) 20 mug (dry weight) of heat-killed Salmonella (SR-11), (iii) 20 mug (dry weight) of immunogenic ribosomal subfractions, or (iv) 20 mug of ribonucleic acid (RNA) subfractions were passively transferred to normal unimmunized mice. The ability of the recipient...

While serotyping and phage typing have been used widely to characterize Salmonella isolates, sensitive subtyping methods that allow for evolutionary analyses are essential for examining Salmonella transmission, ecology, and evolution. A set of 25 Salmonella enterica isolates, representing five clinically relevant serotypes (serotypes Agona, Heidelberg, Schwarzengrund, Typhimurium, and Typhimuri...

AIM This study was carried out to determine the prevalence, distribution, and identification of Salmonella serotypes in diarrheagenic infants and young animals, including sewage waste and fresh vegetables. MATERIALS AND METHODS A total of 550 samples were processed for the isolation of Salmonella spp., using standard microbiological and biochemical tests. Further polymerase chain reaction (PC...

Introduction: In Iran, invasive nontyphoidal Salmonella (iNTS) disease causes severe bacteremic illness among children <5 years old. The global yearly incidence of iNTS disease in children was reported to be in the 3.4 (range&nbsp; 2.1-6.5) million cases,&nbsp; (overall incidence 49 cases (range 30-94) per 100,000 population), the iNTS case-fatality ratio (CFR) of 20% yielded 681,316&nbsp; deat...
