What Is Salmonella Typhi?

Salmonella typhimurium is spore-free (0.6-0.9) × (1-3) micrometers without spores, and generally has no capsules. Except for Salmonella gallisepticum and Salmonella typhimurium, most of them have flagella around them, causing Salmonella bacteria that cause typhoid fever.

Salmonella typhi

Right!

Salmonella typhimurium is spore-free (0.6-0.9) × (1-3) micrometers without spores, and generally has no capsules. Except for Salmonella gallisepticum and Salmonella typhimurium, most of them have flagella around them and cause Salmonella bacteria.

Salmonella bacteria that cause typhoid fever. Bacteria rod-shaped, flagella around the body, can produce endotoxin. Endotoxin injection into rabbit veins can cause human-like lesions, such as fever, leukopenia, etc., and large injections can cause death.

Surveillance of resistance to 591 Salmonella typhi isolates from Suzhou from 1987 to 1992 found that 4 years after the epidemic of resistant strains from 1987 to 1988, typhoid had recovered sensitivity to most antibiotics. The plasmid detection of drug-resistant strains, and the results of transfer, transformation, and removal tests proved that the multi-drug resistance of the trauma rods was mediated by a plasmid with a molecular weight of 98.6 Mdal. ^[1]
