[77][78], S. enterica, through some of its serotypes such as Typhimurium and Enteritidis, shows signs of the ability to infect several different mammalian host species, while other serotypes such as Typhi seem to be restricted to only a few hosts. “Existen más de 2 mil 500 serotipos de Salmonella con diferentes grados de adaptación y patogenicidad. Newport persistence in tomatoes have been reported to be similar to those selected for in sv. Some pet foods may be contaminated with salmonella and can infect animals. Características generales del organismo Salmonella spp. [51], Most infections are due to ingestion of food contaminated by animal feces, or by human feces, such as by a food-service worker at a commercial eatery. Las bacterias de la salmonella están presentes en el tracto intestinal de personas y animales sanos, principalmente en ganado vacuno, porcino, aves de corral y domésticos. [70], The switch to virulence gives access to a replication niche inside the host (such as humans), and can be summarised into several stages:[citation needed], Nontyphoidal serotypes preferentially enter M cells on the intestinal wall by bacterial-mediated endocytosis, a process associated with intestinal inflammation and diarrhoea. [18], Looking at the comparison of xMAP Salmonella Serotyping Assay With Traditional Serotyping and Discordance Resolution by Whole Genome Sequencing, study showed that molecular serotyping is promising as a rapid method for Salmonella serotyping. Febre tifoide é uma doença causada por uma enterobactéria e pode causar a morte. Dentro de esta última se sitúan los dos serotipos más significativos para la Seguridad Alimentaria, la salmonella typhi y la salmonella enteritis, por ser los predominantes en Europa y los más destacados a nivel mundial en casos de salmonella transmitida de animales a humanos. Thus, Salmonella species must face attack by molecules that challenge genome integrity. Por lo tanto, la cocción adecuada y la higiene durante la manipulación de los alimentos puede prevenir en una gran medida las infecciones causadas por la Salmonella.

La septicemia causada por Salmonella se ha asociado con una subsecuente infección de casi todos los órganos del sistema. Historically, salmonellae have been clinically categorized as invasive (typhoidal) or noninvasive (nontyphoidal salmonellae) based on host preference and disease manifestations in humans. Después de una infección, muchos individuos siguen albergando las bacterias y eliminándolas, algunos en forma permanente. This microorganism is able to adapt to temperature, pH, and water .

Salmonella bacteria live in the intestines of people, animals and birds. As Baumler et al. Son las enterobacterias más complejas, con más de 2.400 serotipos. Life-threatening complications also may develop if the infection spreads beyond the intestines. Buchmeier et al.,[77] 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. [15], Serotyping is done by mixing cells with antibodies for a particular antigen. ¡Gracias! Posteriormente, las muestras deben cultivarse en agar sangre o chocolate y MacConkey (AMC). Salmonella spp. [55] Bacterial colonies may also become trapped in mucus produced in the esophagus. Salmonella can also be detected and subtyped using multiplex[24] or real-time polymerase chain reaction (qPCR)[25] from extracted Salmonella DNA. While the infection can last a few days and pass without any treatment, some instances, particularly severe diarrhea, require treatment.

[65], Typhoid fever is caused by Salmonella serotypes which are strictly adapted to humans or higher primates—these include Salmonella Typhi, Paratyphi A, Paratyphi B, and Paratyphi C. In the systemic form of the disease, salmonellae pass through the lymphatic system of the intestine into the blood of the patients (typhoid form) and are carried to various organs (liver, spleen, kidneys) to form secondary foci (septic form). Salmonella. Their accomplishments and strategies to reduce Salmonella infection are presented in the plans.
