1. Earlier this month traces of Salmonella typhimurium were found in swabs taken from the hen house.

2. It can inhibit the mutagenic effects of Salmonella typhimurium.

3. Using attenuated Salmonella typhimurium as vectors to deliver DNA vaccines is a novel promising method to control avian influenza.

4. A titration assay for ornithine decarboxylase induced in Salmonella typhimurium is reported in this paper.

5. The transformed Salmonella typhimurium was administrated to mice by oral or abdominal injection,() HAVIgG antibody was found in the mice sera.

6. Methods The Salmonella typhimurium reverse mutation assay was used to study menadiol sodium diphosphate induced mutation. The strains of TA97, TA98, TA100, TA102 were used in this experiment.

7. Methods: Phage sensitivity of 3 strains of Salmonella typhimurium Lforms induced in vitro and their parents were tested by 12 strains of typing bacteriophages of Salmonella typhimurium.

8. Conclusion Hepatitis A vaccine with attenuated Salmonella typhimurium as vector can induce immune response.

9. And then Salmonella Typhimurium were applied to study the problems of human typhoid fever since it could lead to the same disease in murine.

10. It is alleged that the flock is infected with Salmonella typhimurium.

11. It was test on petri plates with two mutants of Salmonella typhimurium—TA98 and TA100.

12. The gastrointestinal tract (55.07%) followed by the lower respiratory tract(22.7%) was the most infected site. The salmonella typhimurium was the most bacterial pathogen.

13. Aim:To investigate the influence of the L-forms variation of Salmonella typhimurium on their plasmids and outer membrane proteins.

14. Similarly, the type of diet did not appear to influence host resistance to Salmonella typhimurium.

15. This paper presents a clinical analysis of 176 cases of salmonella typhimurium enteritis admitted to the hospital.

16. Considering its tumor targeting, replication in tumor tissues and anti-tumor effects, attenuated Salmonella typhimurium has offered a new approach to tumor therapy.

17. This study should encourage further work towards the development of recombined attenuated Salmonella typhimurium vaccine against IBV.

18. Objective To confirm AcrAB - TolC system mediated the multiple antimicrobial resistance in Salmonella typhimurium.

19. Objective To construct hepatitis A virus vaccine with attenuated Salmonella typhimurium as vector, and study its immune response.

20. Objective To study the factors of affecting the efficacy of Salmonella Typhimurium (ST) enteritis.

21. In order to establish a rapid and accurate detection method of Salmonella typhimurium contamination in duck-slaughtering chain, PCR was used to monitor duck-slaughtering chain in real time.

22. Objective: To investigated the effect on phage sensitivity resulting from the Lforms variation of Salmonella typhimurium.
