| SALMONELLA TYPHI |
The Salmonella genus is characterized by Gram-negative bacterium, asporigens and facultative anaerobes. They ferment glucose, produce gases, degrade sulfurized proteins by producing H 2 S, reduce nitrates and do not produce cytochrome oxidase
. Most are non-fermentative lactose. Possessing peritrichous flagella, they are all moveable except S. Gallinarum-Pullorum.
Salmonella bacterium are present in the environment, in soil and in water, and can be found as parasites in the intestines of animals and humans (eg Salmonella typhimurium ) or exclusively of man (es. Salmonella typhi e Salmonella paratyphi A e C).
In humans, these various serotypes cause different groups of infectious diseases:
- Salmonellosis is the most common form of salmonella disease and manifests itself as localized bowel infections (food toxins) and is caused by minor salmonellas, namely Salmonella typhimurium and < em> Salmonella enteritidis .
Enteric fever: Typhoid and parathyroid fever, systemic manifestations, respectively caused by Salmonella typhi serotypes and Salmonella paratyphi.
Sepsis: infection associated with the serum Salmonella cholaeresuis and whose risk of onset is higher in geriatric, pediatric and immunocompromised patients.
