In 2008-2009, a nationwide outbreak of S typhimurium was traced to peanut products and frozen chicken products. Because the contaminated peanuts were used to make a variety of products that were distributed across the country, this outbreak highlighted how difficult it can be to trace the source of an outbreak.

Risk factors for Salmonella infections include a variety of foods. Meats such as chicken and pork have the possibility to be contaminated. A variety of vegetables and sprouts may also have salmonella. Lastly, a variety of processed foods such as chicken nuggets and pot pies may also contain this bacteria.[54] An uncommon complication called reactive arthritis involves the development of joint pains, irritation of the eyes, and pain on urination. Reactive arthritis may persist for months to years and can lead to chronic arthritis.About 2,000 serotypes of nontyphoidal Salmonella are known, which may be responsible for as many as 1.4 million illnesses in the United States each year. People who are at risk for severe illness include infants, elderly, organ-transplant recipients, and the immunocompromised.[37] Linam WM, Gerber MA.

Preventing the spread of infection

Salmonella is a genus of rod-shaped (bacillus) Gram-negative bacteria of the family Enterobacteriaceae. The two species of Salmonella are Salmonella enterica and Salmonella bongori. S. enterica is the type species and is further divided into six subspecies[2] that include over 2,600 serotypes.[3] Salmonella was named after Daniel Elmer Salmon (1850–1914), an American veterinary surgeon.[4] WGS showed that Salmonella bacteria isolated from sick people and the cereal were closely related genetically.

The AvrA toxin injected by the SPI1 type III secretion system of S. Typhimurium works to inhibit the innate immune system by virtue of its serine/threonine acetyltransferase activity, and requires binding to eukaryotic target cell phytic acid (IP6).[64] This leaves the host more susceptible to infection. Eggs are one of the world's healthiest foods, but is it safe to eat them raw? Learn about the health benefits and risks of eating raw eggs.

WGS showed that Salmonella bacteria isolated from sick people and the cereal were closely related genetically. This result provides more evidence that people in this outbreak got sick from eating.. Children, especially those under 5, are more likely than adults to get sick from salmonella. Older adults and people with weak immune systems are also more likely to be infected. Other risk factors include: Salmonella-Shigella (SS) Agar: Used for selective recovery of Salmonella from stool culture (contains five times the concentration of bile salts compared with MacConeky Agar) NTS infection usually manifests as self-limited acute gastroenteritis but may also cause severe invasive infections (almost exclusively among children or immunosuppressed individuals). The incidence of salmonellosis in the United States is greatest among children younger than 5 years (61.8 per 100,000 people), with a peak among those younger than 1 year.

Nontyphoidal serotypes are more common, and usually cause self-limiting gastrointestinal disease. They can infect a range of animals, and are zoonotic, meaning they can be transferred between humans and other animals. Typhoidal serotypes include Salmonella Typhi and Salmonella Paratyphi A, which are adapted to humans and do not occur in other animals.

  6. Mechanisms of infection differ between typhoidal and nontyphoidal serotypes, owing to their different targets in the body and the different symptoms that they cause. Both groups must enter by crossing the barrier created by the intestinal cell wall, but once they have passed this barrier, they use different strategies to cause infection.

Alena Klochko, MD Infectious Disease Physician, Orlando Health, FloridaDisclosure: Nothing to disclose. Salmonella (plural salmonellae, salmonellas, or salmonella) are any of the various rod-shaped, gram-negative bacteria that comprise the genus Salmonella (family Enterobacteriaceae), some of which are pathogenic The incidence of Salmonella infections in the United States has been stable since 2004 but has decreased approximately 8% from 1996-1998 levels. [18] In 2007, the reported annual incidence of salmonellosis was 14.9 cases per 100,000 population. [18] The true annual burden of NTS infection in the United States is calculated to be 520 cases per 100,000 population, compared with 13.4 laboratory-confirmed cases per 100,000 population per year. This reflects an estimate of approximately 38.6 cases of NTS infection for each culture-confirmed case. [19] Eating contaminated food can lead to diarrhea, nausea, vomiting, and abdominal pain. It can also cause inflammation and develop into stomach flu. The…Virulence factors of salmonellae are complex and encoded both on the organism's chromosome and on large (34-120 kd) plasmids. Some areas of active investigation include the means by which salmonellae attach to and invade the intestine, survive within phagosomes, effect a massive efflux of electrolytes and water into the intestinal lumen, and develop drug resistance. Several Salmonella pathogenicity islands have been identified that mediate uptake of the bacteria into epithelial cells (type III secretion system [TTSS]), nonphagocytic cell invasion (Salmonella pathogenicity-island 1 [SPI-1]), and survival and replication within macrophages (Salmonella pathogenicity-island 2 [SPI-2], phoP/phoQ).

If they have a high fever, you may want to give acetaminophen. As with adults, they should drink lots of water.Much of the success of Salmonella in causing infection is attributed to two type III secretion systems (T3SS) which are expressed at different times during the infection. The T3SS-1 enables the injection of bacterial effectors within the host cytosol. These T3SS-1 effectors stimulate the formation of membrane ruffles allowing the uptake of Salmonella by nonphagocytic cells. Salmonella further resides within a membrane-bound compartment called the Salmonella-Containing Vacuole (SCV). The acidification of the SCV leads to the expression of the T3SS-2. The secretion of T3SS-2 effectors by Salmonella is required for its efficient survival in the host cytosol and establishment of systemic disease.[62] In addition, both T3SS are involved in the colonization of the intestine, induction of intestinal inflammatory responses and diarrhea. These systems contain many genes which must work co-operatively to achieve infection.

Health officials in several states collected Kellogg’s Honey Smacks cereal from retail locations and ill people’s homes for testing. Laboratory testing identified the outbreak strain of Salmonella Mbandaka in a sample of unopened Kellogg’s Honey Smacks cereal collected from a retail location in California. Laboratory testing also identified the outbreak strain in samples of leftover Kellogg’s Honey Smacks cereal collected from the homes of ill people in Montana, New York, and Utah.State and local health officials continue to interview ill people and ask questions about the foods they ate and other exposures in the week before they became ill. Fifty-five (85%) of 65 people interviewed reported eating cold cereal. In interviews, 43 people specifically reported eating Kellogg’s Honey Smacks cereal. Ill people in this outbreak reported this cereal more often than any other cereals or food items.Some foods contain toxins that are harmful to pregnant women and their developing baby. Read more about these toxins and how to avoid them.

There are over 2,500 subtypes, including animal and human strains. Some are present in animals but can also affect humans. Fewer than 100 strains of Salmonella bacteria are likely to infect people.Public health investigators used the PulseNet system to identify illnesses that were part of this outbreak. PulseNet is the national subtyping network of public health and food regulatory agency laboratories coordinated by CDC. DNA fingerprinting is performed on Salmonella bacteria isolated from ill people by using techniques called pulsed-field gel electrophoresis (PFGE) and whole genome sequencing (WGS). CDC PulseNet manages a national database of these DNA fingerprints to identify possible outbreaks. WGS gives a more detailed DNA fingerprint than PFGE. WGS performed on bacteria from ill people in this outbreak showed that they were closely related genetically. This means they were more likely to share a common source of infection.Lack of hygieneContamination and infection can occur if people do not keep kitchen surfaces clean and do not wash their hands during food preparation, after using the bathroom, and after changing a baby’s diapers. When a person has the bacteria on their hands, they can spread it by touching other people or by touching frequently used objects and surfaces.A hallmark of Salmonella pathogenesis is the ability of the bacterium to survive and proliferate within phagocytes. Phagocytes produce DNA-damaging agents such as nitric oxide and oxygen radicals as a defense against pathogens. Thus, Salmonella species must face attack by molecules that challenge genome integrity. Buchmeier et al.[67], showed that mutants of S. enterica lacking RecA or RecBC protein function are highly sensitive to oxidative compounds synthesized by macrophages, and furthermore these findings indicate that successful systemic infection by S. enterica requires RecA- and RecBC-mediated recombinational repair of DNA damage.[67][68]

In the salmonella Typhi and enteric diseases, a distinction is. Cause of Typhi salmonellosis (Typhi fever, paraTyphi A, B and C), Salmonella enterica serotype typhi or paratyphi A.. Small rodents such as hamsters, as well as baby chicks and ducklings, may also carry the bacteria, and contamination of food after handling these animals may also result in salmonellosis. Reptiles may also harbor Salmonella bacteria. In the 1970s, outbreaks were associated with baby turtles kept as pets. Further, the infection may be spread by contaminated surfaces (such as cutting boards) that have had contact with contaminated foods.Due to being considered sporadic, between 60% to 80% of salmonella infections cases go undiagnosed.[50]In March 2010, data analysis was completed to estimate an incidence rate of 1140 per 100,000 person-years. In the same analysis, 93.8 million cases of gastroenteritis were due to salmonella infections. At the 5th percentile the estimated amount was 61.8 million cases and at the 95th percentile the estimated amount was 131.6 million cases. The estimated number of deaths due to salmonella was approximately 155,000 deaths.[51] In 2014, in countries such as Bulgaria and Portugal, children under 4 were 32 and 82 times more likely, respecively, to have a salmonella infection.[52] Those who are most susceptible to infection are: children, pregnant women, elderly people, and those with deficient immune systems.[53] Currently, Salmonella species have the serologically defined names appended as serovars or serotypes. For instance, the current nomenclature of Salmonella typhi is S enterica serovar Typhi. S enterica is preferred over confusing name S choleraesuis, which is also the name of a commonly isolated serotype. [4] To date, more than 2500 serovars of S enterica have been described. Certain serovars are host-restricted, while others have a broad host range. [5] Kurtz JR, Goggins JA, McLachlan JB. Salmonella infection: Interplay between the bacteria and host immune system. Immunol Lett. 2017 Oct. 190:42-50. [Medline]. [Full Text].

S. enterica genomes have been reconstructed from up 6,500 year old human remains across Western Eurasia, which provides evidence for geographic widespread infections with systemic S. enterica during prehistory, and a possible role of the Neolithization process in the evolution of host adaptation.[78] [79] Additional reconstructed genomes from colonial Mexico suggest S. enterica as the cause of cocoliztli, an epidemic in 16th-century New Spain.[80] Salmonella species lead predominantly host-associated lifestyles, but the bacteria were found to be able to persist in a bathroom setting for weeks following contamination, and are frequently isolated from water sources, which act as bacterial reservoirs and may help to facilitate transmission between hosts.[29] Salmonella is notorious for its ability to survive desiccation and can persist for years in dry environments and foods.[30] Salmonella enfeksiyonu (salmonelloz) bağırsak sistemini etkileyen yaygın bir bakteriyel hastalıktır.

Illness from these bacteria is officially called salmonellosis. It can cause an upset stomach, diarrhea, fever, and pain and cramping in your belly. Most people get better on their own at home within 4 to 7 days.

Typhimurium, S. Enterica, typhoid fever, enteric fever, salmonellosis Salmonella and Salmonellosis (page 3). (This chapter has 5 pages) The Vi antigen of S typhi is important in preventing antibody-mediated opsonization and complement-mediated lysis. Through the induction of cytokine release and via mononuclear cell migration, S typhi organisms spread through the reticuloendothelial system, mainly to the liver, spleen, and bone marrow. Within 14 days, the bacteria appear in the bloodstream, facilitating secondary metastatic foci (eg, splenic abscess, endocarditis). In some patients, gallbladder infection leads to long-term carriage of S typhi or S paratyphi in bile and secretion to the stool. [17] As a rule, infection with nontyphoidal salmonellae generally precipitates a localized response, while S typhi and other especially virulent strains invade deeper tissues via lymphatics and capillaries and elicit a major immune response.

People and animals can carry salmonella in their intestines and their feces. The bacteria often spread through contaminated foods. Common food sources of salmonella infection include:Salmonella species are facultative intracellular pathogens.[7] Salmonella can invade different cell types, including epithelial cells, M cells, macrophages, and dendritic cells.[47] As facultative anaerobic organism, Salmonella uses oxygen to make ATP in aerobic environment (i.e., when oxygen is available). However, in anaerobic environment (i.e., when oxygen is not available) Salmonella produces ATP by fermentation; by substituting one or more of four less efficient electron acceptors than oxygen at the end of the electron transport chain: sulfate, nitrate, sulfur, or fumarate.

Some of the microorganisms are killed in the stomach, while the surviving ones enter the small intestine and multiply in tissues. Gastric acidity is responsible for the destruction of the majority of ingested bacteria, but Salmonella has evolved a degree of tolerance to acidic environments that allows a subset of ingested bacteria to survive.[48] Bacterial colonies may also become trapped in mucus produced in the esophagus. By the end of the incubation period, the nearby host cells are poisoned by endotoxins released from the dead salmonellae. The local response to the endotoxins is enteritis and gastrointestinal disorder.

Successful forms of prevention come from existing entities such as: the FDA, United States Department of Agriculture, and the Food Safety and Inspection Service. All of these organizations create standards and inspections to ensure public safety in the U.S. For example, the FSIS agency working with the USDA has a Salmonella Action Plan in place. Recently, it received a two-year plan update in February 2016. Their accomplishments and strategies to reduce Salmonella infection are presented in the plans.[55] The Centers for Disease Control and Prevention also provides valuable information on preventative care, such has how to safely handle raw foods, and the correct way to store these products. In the European Union, the European Food Safety Authority created preventative measures through risk management and risk assessment. From 2005 to 2009, the EFSA placed an approach to reduce the exposure of salmonella. Their approach included risk assessment and risk management of poultry, which resulted in a reduction of infection cases by one half.[56] In Latin America an orally administered vaccine for Salmonella in poultry developed by Dr. Sherry Layton has been introduced which prevents the bacteria from contaminating the birds.[57] Illnesses that occurred after May 22, 2018, might not yet be reported due to the time it takes between when a person becomes ill and when the illness is reported. This takes an average of 2 to 4 weeks. Please see the Timeline for Reporting Cases of Salmonella Infection for more details.Freeman R, Dabrera G, Lane C, Adams N, Browning L, Fowler T, et al.
