How can salmonella typhimurium be prevented

Young children children in diapers that are experiencing diarrhea should not be allowed to go swimming or attend daycare. Preventing Salmonellosis Minimizing Your Risk Wash your hands Wash hands after using the bathroom and changing diapers, and before handling or eating any food. Make sure that persons with diarrhea, especially children, wash their hands carefully and frequently with soap to reduce the risk of spreading the infection. Always wash hands after contact with farm animals, pets, animal feces, and animal environments.

Hand Hygiene Wash Your Hands! Keep your food preparation areas clean Keep raw meat and poultry separate from produce and other foods when shopping for and storing groceries. Children, especially infants, are most likely to get sick from it.

People at risk for more serious complications from a Salmonella infection include those who:. In these higher-risk groups, most doctors will treat an infection with antibiotics to prevent it from spreading to other parts of the body.

Antibiotics do not appear to help a healthy person whose infection is not severe — and may actually lengthen the amount of time the person will carry the bacteria. Because many different illnesses can cause similar symptoms such as nausea, fever, cramping, and diarrhea , doctors may send a stool poop sample to the lab for testing.

A severe Salmonella infection will require more testing to see which specific germ is causing the illness and which antibiotics can be used to treat it. If you have salmonellosis and a healthy immune system, your doctor may let the infection pass without giving any medicines. If you have a fever, you may want to take acetaminophen to lower the temperature and relieve cramping. As with any infection that causes diarrhea, it's important to drink plenty of liquids to avoid dehydration.

Salmonellosis symptoms can take from 6 to 72 hours to start after someone ingests the bacteria. In most people, the illness lasts for 4 to 7 days after symptoms begin. Hand washing is a powerful way to guard against Salmonella infections.

So wash your hands well and often, particularly after trips to the bathroom and before handling food. Follow Salmonella. Links with this icon indicate that you are leaving the CDC website.

To compare the amount of the feed intake before and after the Salmonella-infected diarrhea, the feed amount was restricted to g a day. Also the water amount was restricted to ml a day, too. Live Salmonella bacteria counts. To confirm the proliferation of the pathogenic bacteria, the feces of the experimental animals were aseptically collected at metabolic cage for 24 hr.

One gram of the feces of each group of rats was homogenized in 9 ml of a saline solution and serial-diluted 10 times with PBS. Morphology of Salmonella colony in pure culture and infected feces were similar Cytokine assay. Three hours after the oral administration of the pathogenic bacterium S.

Microscopic observation. Statistical analysis. The data were processed with Graphpad Prism TM 5. Comparison of the coaggregation and adhesion abilities of the probiotics. To confirm the coaggregation abilities of the Salmonella and LAB, the differences in the natural sedimentation of the LAB live bacteria, hk bacteria and Salmonella were investigated.

The LAB live bacteria showed As such, hk better than live bacteria have higher coaggregation with Salmonella typhimurium Fig. After treat the S. In much of the microscopic field, the hk probiotics showed better adhesion ability than the live probiotics Fig. Comparison of the body temperature and the body weight.

After the Salmonella infection, the changes in the body temperature were monitored for 0, 1, 3, 6, 9, 12 and 24 hr through a rectal investigation.

In the negative control NC group to which Salmonella was not administered, the body temperature was consistently maintained, whereas in the S.

Nine hours later, the body temperature abruptly increased by 2. In comparison, the LAB group showed a decrease in body temperature from 0 hr to 6 hr, and the decrease was significantly less than that in the SA body temperature.

Particularly, the 10 10 of the hk bacteria treatment group showed the least difference in the body temperature decrease. Since then, no abrupt increase in the body temperature caused by immune responses was observed Fig.

In terms of the change in the body weight after the Salmonella infection, the NC group that did not receive Salmonella treatment showed an increased body weight, whereas the other groups that received Salmonella treatments showed a decreased body weight.

Particularly, the SA group to which Salmonella was administered showed a Measurement of the feed intake and the water consumption. In terms of the daily amount of the feed intake, the NC group showed In comparison, the live or hk LAB group reported a 24 hr intake of In terms of the amount of purified water intake, the NC group reported The hk bacteria and live bacteria groups showed a Salmonella cell count in the feces.

To investigate the Salmonella changes in the feces of the experimental animals, the total number of fecal bacteria was confirmed using a plate. The total numbers of bacteria in 1 g of feces were: NC, 1. These results confirmed that the Salmonella infection group showed a statistically significant increase in the total number of bacteria compared with the non-infection group.

These results suggest that the live probiotics act to inhibit the growth of S. Pro-inflammatory cytokine in serum. In the serum analysis to confirm the effects of intestinal protection and diarrhea prevention after the infection, the levels of the proinflammatory cytokine TNF-alpha and IL-1 beta in all the LAB groups were lower than in the SA group. Considering that the expression level was lower in the live bacteria than in the hk bacteria, the LAB administration was confirmed to have reduced the development of intestinal mucosal inflammation caused by Salmonella.

Bacterial detection in the colon. To confirm the presence of LAB and Salmonella in the intestinal tissues of the rats that were sacrificed after the experiments, micro-sectioning and gram staining were conducted. The presence of Salmonella was confirmed only in the SA group. In live probiotics group, the adhesion to the intestine was confirmed. Whereas, in hk Probiotics groups, the adhesion to the intestine was not confirmed as expected Fig. The most serious problem in antibiotics treatment to Salmonellosis is the secondary damage caused by the dead Salmonella Antibiotics-resistant Salmonella poses another problem To overcome these problems, antibiotics should be used discreetly, and the secondary damage from the dead Salmonella should be overcome, in addition to the removal of the Salmonella.
