(�� Serotypes Salmonella Typhimurium, Salmonella enteritidis, Salmonella newport, and Salmonella heidelberg are most often responsible for food poisoning; Salmonella Cholerasuis and Salmonella Dublin also cause diarrheic diseases.

Salmonella bacteraemia is a condition whereby the bacteria enter the bloodstream after invading the intestinal barrier. Invasive NTS is endemic in underdeveloped countries, especially in sub-Saharan Africa, with high occurrence rates in children below 3 years old and human immunodeficiency virus (HIV)-infected patients, and these invasive strains confer a mortality rate up to 25% (Gordon et al. 1-8. J Infect. �*Jl��N�N [QxMD MEDLINE Link]. [26] By other estimates, a total of 26.9 million typhoid fever episodes occurred in 2010. Prabha A, Mohanan, Pereira P, Raghuveer CV. The emergence of antibiotic-resistant foodborne pathogens has raised the concern of the public as these pathogens are more virulent, causing an increase in the mortality rate of infected patients (Chiu et al. Si el proveedor de atención médica sospecha . The emergence of Salmonella with antimicrobial resistance is mainly promoted by the use of antibiotics in animal feed to promote the growth of food animals, and in veterinary medicine to treat bacterial infections in those animals (Hyeon et al.

Based on data from 2005 to 2006 presented by the National Antimicrobial Resistance Monitoring System (NARMS), 84% of clinical isolates of NTS displayed MDR phenotype and 4.1% of the isolates had reduced susceptibility to cephalosporins in the USA. 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).

The emergence of multi-drug-resistant (MDR) Salmonella serotypes is having a great impact on the efficacy of antibiotic treatment, and an increasing prevalence of MDR strains may lead to an increase in mortality rates of Salmonella infections. Francisco Talavera, PharmD, PhD Adjunct Assistant Professor, University of Nebraska Medical Center College of Pharmacy; Editor-in-Chief, Medscape Drug ReferenceDisclosure: Received salary from Medscape for employment. Almost all strains of Salmonella are pathogenic as they have the ability to invade, replicate and survive in human host cells, resulting in potentially fatal disease. Since humans are the only reservoir of typhoid Salmonella, carriers of S. Typhi and S. Paratyphi are responsible for the spreading of enteric fever in endemic regions, as the common transmission route is the ingestion of water or food contaminated with the faeces of chronic carriers (Bhan et al. Intern Med. Kurtz JR, Goggins JA, McLachlan JB. Compared to typhoid infections, NTS infections have a shorter incubation period (6–12 h) and the symptoms are usually self-limiting and last only for 10 days or less (Crump et al. enterica subtyping: gold standards and alternatives.

(�� Under normal circumstances, the presence of the bacterial foreign body would activate the host cell immune response, resulting in the fusion of the lysosomes and the secretion of digesting enzymes to degrade the intracellular bacteria. Through the stomach, the bacteria reach the small intestine. [22] 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. Data show that patients infected with MDR Salmonella strains are more ill and septic at the onset of the disease, and the illness is typically accompanied by high fever, enlargement of the spleen and liver, and abdominal swelling (Buch et al. 0000011762 00000 n Salmonella was first discovered and isolated from the intestines of pigs infected with classical swine fever, by Theobald Smith in 1855. 2006). 2000 Jul.

N Engl J Med. NTS infections are characterized by gastroenteritis or ‘stomach flu’, an inflammatory condition of the gastrointestinal tract which is accompanied by symptoms such as non-bloody diarrhoea, vomiting, nausea, headache, abdominal cramps and myalgias. As for NTS, the number of strains developing MDR phenotype has increased in many countries since the first emergence of MDR S. Typhimurium DT104 strains in 1990 (Helms et al. 0000000016 00000 n Virulence (Vi) antigens, a special subtype of K antigen, are found only in three pathogenic serotypes: Paratyphi C, Dublin and Typhi. 153:517-25.

Currently, the Centers for Disease Control and Prevention (CDC) uses the nomenclatural system of Salmonella recommended by the World Health Organization (WHO) Collaborating Centre (Popoff et al.

Infection with nontyphoidal salmonellae typically produces a self-limiting gastroenteritis, and dehydrated patients occasionally require hospitalization.

Avian salmonellosis (sal-moh-neh-loh-sis) refers to the infection of birds with a bacterium called Salmonella typhimurium, which is a specific type of Salmonella of which there are more than 2,500 . [13] Powdered infant formula has been implicated in two consecutive large outbreaks of S enterica serotype Agona among infants in France. Gastrointestinal complications of NTS infections include cholecystitis, pancreatitis and appendicitis, while the perforation of the terminal ileum has no association with NTS infections (Hohmann 2001).

[2], Multidrug-resistant typhoid fever in childhood is associated with increased risk of mortality, especially in infancy, Some serotypes of Salmonella have begun to develop resistance towards broad-spectrum cephalosporins as a result of mutated genes that encode for extended-spectrum β-lactamases, hydrolysing antibiotics with β-lactam rings such as cephalosporin and cephamycins (Carattoli et al.

Traditionally, Salmonella species were named in accordance with the Kaufmann-White typing system, defined by different combinations of somatic O, surface Vi, and flagellar H antigens. Mortality rates associated with typhoid fever are similarly low in the United States (< 1%), but mortality rates of 10-30% have been reported in some Asian and African countries. 3:CD001261.

For instance, the current nomenclature of Salmonella typhi is S enterica serovar Typhi. Similar to enteric fever, high fever is the characteristic symptom of bacteraemia, but without the formation of rose spots as observed in patients with enteric fever. [QxMD MEDLINE Link]. In contrast, the invasive disease caused by NTS is less frequently reported in Asia (Khan et al. 0000323098 00000 n Salmonella infections. GBA-808138 and GBA-808813) awarded to L-HL. Diarrhoea is more commonly observed in children, whereas patients with immunosuppression are more likely to develop constipation (Thielman & Guerrant 2004). The difference in the clinical manifestation is believed to be associated with the presence of the spv (Salmonella plasmid virulence) gene in NTS which causes non-typhoidal bacteraemia, based on genetic analysis (Guiney & Fierer 2011). Gastroenteritis is the most common Salmonella infection worldwide, accounting for 93.8 million cases which result in 155,000 deaths per year (Majowicz et al. 5th ed. trailer Cochrane Database Syst Rev.

A surveillance study on 135,000 clinical isolates of NTS was conducted in Europe from 2000 to 2004, and the data showed that 15% of the isolates displayed MDR phenotype and 20% of the isolates were resistant to nalidixic acid (Meakins et al.

In spite of improvements in hygiene and sanitation, the incidence of NTS infections continues to increase, creating a burden in both industrialized and underdeveloped countries (Majowicz et al.
