Salmonellosis is a symptomatic infection caused by bacteria of the Salmonella type. [1] It is the most common disease to be known as food poisoning (though the name refers to food-borne illness in general), these are defined as diseases, usually either infectious or toxic in nature, caused by agents that enter the body through the ingestion of food.
Humans are the only animals infected. [1] Diagnosis may be based on symptoms and confirmed by either culturing the bacteria or detecting the bacterial DNA in the blood, stool, or bone marrow. [1] [3] Culturing the bacteria can be difficult. [3] Bone-marrow testing is the most accurate. [4] Symptoms are similar to those of many other infectious ...
Salmonella species can be found in the digestive tracts of humans and animals, especially reptiles. Salmonella on the skin of reptiles or amphibians can be passed to people who handle the animals. [39] Food and water can also be contaminated with the bacteria if they come in contact with the feces of infected people or animals. [40]
Without treatment, symptoms may last weeks or months. [5] Diarrhea may be severe, but is uncommon. [7] Other people may carry it without being affected, but are still contagious. [8] Typhoid fever is a type of enteric fever, along with paratyphoid fever. [2] Salmonella enterica Typhi is believed to infect and replicate only within humans. [9]
Color-enhanced scanning electron micrograph showing Salmonella Typhimurium (red) invading cultured human cells. Salmonella is a bacterium that produces the symptoms of diarrhoea, fever and abdominal cramps in infected individuals 12-72 hours after exposure. Most people recover without treatment and the illness usually lasts for 4-7 days. [11]
Salmonella bongori was previously considered a subspecies of S. enterica, but it is now the other species in the genus Salmonella. Most of the human pathogenic Salmonella serovars belong to the enterica subspecies. These serogroups include S. Typhi, S. Enteritidis, S. Paratyphi, S. Typhimurium, and S. Choleraesuis.
The various outbreaks of Salmonella serotypes in the U.S. and abroad began at different points either in late 2011 or early 2012; however, all cases were concluded at the end of 2012. Those who were infected either persisted through the symptoms or expired from Salmonella ' s destruction to their immune system. [3]
Salmonella bongori is a pathogenic bacterium belonging to the genus Salmonella, and was earlier known as Salmonella subspecies V or S. enterica subsp. bongori or S. choleraesuis subsp. bongori. It is a gram-negative , rod-shaped bacterium (bacillus) , which causes a gastrointestinal disease called salmonellosis , characterized by cramping and ...
