Salmonella species are intracellular pathogens:[4] certain serotypes cause illness. Nontyphoidal serotypes can be transferred from animal-to-human and from human-to-human. They usually invade only the gastrointestinal tract and cause Salmonella food poisoning; symptoms resolve without antibiotics. However, in sub-Saharan Africa they can be invasive and cause paratyphoid fever, which requires immediate treatment with antibiotics.
