Salmonella-Induced Mycotic Aneurysm: A Rare Cause of Vascular Emergency | Chapter 4 |An Overview of Disease and Health Research Vol. 2

 Mycotic aneurysm is a rare but life-threatening vascular complication of systemic infections. Salmonella species commonly cause gastrointestinal infections in humans, but in rare instances, they lead to serious complications, such as mycotic aneurysms, which are potentially fatal. The mortality rates are high due to the risk of rupture without timely intervention. The clinical presentation is often variable, and an early diagnosis requires a high index of clinical alertness. We report a case of a mycotic aneurysm secondary to Salmonella enteritidis infection in an elderly man, which resulted in a rapid clinical deterioration and fatal outcome. This case highlights the need for early evaluation and prompt intervention in elderly patients with non-typhoidal Salmonella bacteremia for possible endovascular infections.

Essential Oils against Salmonella Spp. in the Food | Book Publisher International

The primary objective of the study was to ascertain the antimicrobial effect of various concentrations of basil and thyme essential oils (1. 2.5 and 5%) on growth of two strains of bacteria from the genus Salmonella: Salmonella enteritidis (group D) - epidemic strain and Salmonella enteritidis (subsp. enterica subsp. ebterica serovar Enteritidis (D) ATCC 13076 - reference strain (S. enteritidis ES). The bacteria were introduced into the flour and chicken eggs used to make the pasta with eggs, under laboratory circumstances and in a mimicked industrial manufacturing process. used as ingredients to make the dough for pasta that uses eggs (the samples were exposed at 370C and 460C: the temperature of 370C was chosen because according to the literature data the ideal temperature for growth of bacterial cells of the genus Salmonella is 35 - 370C and 460C was pasta drying temperature applied in the industrial production of pasta and applied in the first phase of research in conditions of simulated production process).

In spite of the samples' enhanced basil and thyme essential oil concentrations. From the control to the target samples, the quantity of S. enteritidis RS and S. enteritidis ES bacterial cells steadily reduced at each subsequent stage of the manufacturing process. On the number of S. enteritidis RS and S. enteritidis ES bacterial cells in the pasta, the effect of the added concentrations of basil and thyme essential oils and the simulated process of pasta production demonstrated a high statistical significance at level p 0.001, while their interaction demonstrated a statistically significant influence at level p 0.01. The number of S. eteritidis RS and S. enteritidis ES bacteria in basic solution (physiological solution plus various concentrations of basil and thyme essential oils) in flour and eggs with micellar solution was statistically significantly impacted by the concentrations of basil and thyme essential oils, according to statistical models.

A Review on the Role of Poultry in Food Borne Salmonellosis and Its Public Health Importance | Chapter 4 | Research Aspects in Agriculture and Veterinary Sciences Vol. 1

 Foodborne disease outbreaks caused by Salmonella germs are a major public health problem. Salmonella is isolated from chicken more frequently than from other livestock animals. Salmonella organisms can damage all aspects of chicken production, including hatcheries, incubators, breeding facilities, commercial layer and broiler raising operations, feed preparation units and factories, transportation networks, commercialization facilities, and slaughterhouses. Because of globalisation, a tainted meal might damage the health of people in multiple nations at the same time. Foodborne salmonellosis caused by poultry products has been observed in several countries around the world, including India. Salmonella enteritidis and S. typhimurium are the most common serovars with public health implications. Antibiotic-resistant serotypes in chicken are on the rise at an alarming rate. Multiple risk variables influence the safety of poultry food. There should be programmes to raise consumer awareness about food safety and to guide food handlers and animal breeders, particularly of poultry, in the safe production of food from farm to table, in order to effectively prevent and manage foodborne salmonellosis.

Occurrence of Typhoidal and Non-typhoidal Salmonellae among Poultry Workers in the Southern, Nigeria: A Recent Study | Chapter 6 | Recent Progress in Microbiology and Biotechnology Vol. 6

 Most developing countries still have endemic typhoid fever and non-typhoidal salmonellosis, which are spread on a large scale through contaminated food and water. Poultry has also been identified as a common food source for Salmonella enteritidis infections since the early 2000s. In Akwa Ibom State, 500 blood, stool, cloaca swab, and egg shell swab specimens were collected from poultry, non-poultry workers, and birds and tested for Salmonella species using standard cultural and serological techniques. Overall, the prevalence rate was 117. (23.4 percent ). Salmonella species were found in all three senatorial districts of the state, in varying percentages. Salmonella isolates were found in 42 (25%) of Uyo senatorial districts, 35 (20.8%) of Eket senatorial districts, and 40 (23.8%) of Ikot Ekpene senatorial districts. Out of 372 human subjects screened, 77 (20.7%) were positive, with 38 (20.4%) isolated from non-poultry workers and 39 (21.0%) isolated from poultry workers in the three senatorial districts. 40 (31.3 percent) of the 128 poultry product samples tested were isolated. 23 (18%) were isolated from cloaca swabs, and 17 (13.3%) were isolated from egg shell swabs. All of the serologically significant Typhoid fever cases in this study were confirmed by blood culture. According to sero-grouping and sample collection source, 23.9 percent S. typhi was isolated. S. gallinarum, S. enteritidis, S. pullorum, S. paratyphi A, and S. typhimurium were isolated from bird Cloaca swab and Egg shell swab among poultry products. Salmonella pullorum and Salmonella typhi were not isolated from humans or poultry. Salmonella serovars such as S. gallinarium, S. typhi, S. typhimurium, and S. enteritidis are prevalent in Akwa Ibom State, and regular consumption of poultry and eggs without proper disinfection and boiling poses a serious public health risk. According to the demographic data obtained in this study, the majority of poultry workers in the Three senatorial districts' residents were between the ages of 21 and 30 (34 percent), 39 percent were non-graduates, and 30.4 percent were secondary school dropouts. Amoxacillin-Clavulanic acid was found to be 100 percent susceptible to S. gallinarum, S. paratyphi A, 93 percent susceptible to S. typhi, and 80 percent susceptible to S. typhimurium, S. enteritidis, and Spullorum. Salmonella gallinarum was completely sensitive to Ciprofloxacin, whereas all isolates were completely resistant to the antibacterial agents Oxacillin and Tylosin. The emergence of multiple drug-resistant Salmonella from humans and poultry suggests that the continued use of drugs as growth promoters in poultry should be reconsidered. Salmonella can also be sourced from other sources.

Immunodominant Epitopes Identified on the LPS from Different Enterobacteria Using Phage Display | Chapter 9 | Recent Progress in Microbiology and Biotechnology Vol. 3

 Context: The etiological agents of intestinal infection are Escherichia coli and Salmonella. The existence of mutual epitopes between lipopolysaccharides (LPSs) of E. was shown by a previous study. O157 coli and Salmonella. Goal: The aim of this research was to identify mimotopes of shared epitopes in various enterobacterial LPSs using phage displays. Methods: We are using IgG anti-LPS from E. Coli O157 and Salmonella for the selection of M13 phage peptide mimotopes. The amino acid sequence of the mimotopes was used to synthesise peptides that were used for rabbit immunisation in turn. ELISA and Western blot assays analysed the antibody reaction of the resulting sera against the LPSs and synthetic peptides (SPs), showing that the same antibody recognised LPS sites. The reactions of human serum samples collected from the general population against the SPs and LPSs were also analysed in a complementary test. 

Results: Sixty phagotopes have been selected from the last biopanning phase. The peptide mimotope amino acid sequence review showed that the S / N / A / PF motif was a typical sequence in 4 of them. SP287/3, SP459/1, SP308/3, and SP073/14 immunised rabbit serum antibodies respond against both their own peptides and separate LPSs. The Western blot test suggests a reaction of sera against both the lateral chains and the LPS cores. The human serum analysis indicates a response to the SPs and LPSs. Conclusion: The conclusion of the study is the antibody responses to S. Typhus, S. S., Urbana. Arizonae, E. Coli O157 LPS obtained from immunised rabbits with SP287/3, SP459/1, SP308/3, and SP073/14 confirms that synthetic peptides are immunogenic mimotopes of the LPSs evaluated and that they can be considered as an alternative mechanism for defence against infections caused by LPSs. E. and Salmonella. However, previous studies with animal models of coli O157 are required to confirm their protective ability. Mimotopes of LPS epitopes of Salmonella and E are the synthetic peptides designed. Coli with immunogenic capabilities. In the design of vaccines against both enterobacteria, these mimotopes may be considered for use.
