typhi on nutrient agar. Gentamicin (10 mg/L) was included in each well except for the control wells, in order to prevent growth of extracellular S. typhi . Both antibiotics showed good in vitro antibacterial effects against S. typhi strains. There were no statistically significant differences ...
Typhi andS.Paratyphi A being strictly restricted to growth in humans, andS.Paratyphi C being able to establish infections in experimental animals quite easily (at moderate infection doses); the host-restriction status ofd-tartrate-negativeS.Paratyphi B is so far unclear. Representing an update on ...
from a calf-virulent strain of the bovine-pathogenic species, Salmonella dublin, has been shown to be non-virulent for mice; and aroA::Tn10 derivatives, presumably non-virulent, have been made by transduction from several recently isolated strains of the human pathogen, Salmonella typhi. ...
typhi are prone to disrupt the intestinal epithelial barrier and spread over the whole body. Interestingly, the invasive Salmonella serovars evolutionally adapted for extraintestinal life are defective in anaerobic metabolic networks54.

typhi is believed to translocate rapidly and efficiently from the lumen of the human intestine through the mucosa to eventually reach the reticuloendothelial system and gall bladder, where, following a relatively long incubation, they precipitate a systemic febrile illness accompanied by a low-level ...

Similarly,S. Salamae could not replicate inside macrophages. Moreover, intracellular replication inS.Way...
