A 55-year-old man with an abdominal aortic aneurysm presented with fever and
abdominal pain
3 weeks after an episode of
Salmonella gastroenteritis
. His symptoms persisted despite antimicrobial therapy. Two abdominal computed tomography (CT) scans showed no evidence of aortitis. His
abdominal pain
worsened and further investigation including a third CT scan demonstrated a leaking aortic aneurysm. The wall of the aorta was shown to contain Gram-negative bacilli. This case illustrates the difficulty in diagnosing bacterial aortitis.

We experienced a hospital outbreak of
salmonella food poisoning
after ingestion of omelet which was the hospital evening meal on August 8, 1999. Total number of patients was sixty-two (Male 25: female 37) and the mean age was 52.1 years old. Salmonella Enteritidis was isolated from the stool in 59 cases. Twenty-one of them were associated with the immunosuppression (12 with malignancy, 6 with DM, one with nephrotic syndrome, one with chronic nephritis and one with allergic purpura). Clinical symptoms of the patients were composed of watery diarrhea (100%), fever (88.7%),
abdominal pain
(82.3%), nausea (45.2%) and vomiting (25.8%). The laboratory data revealed leukocytosis (15/47 = 31.9%), increased CRP (44/46 = 95.7%), elevated creatinin (1/37 = 2.7%) and hypokalemia (5/42 = 11.9%). MICs of 20 strains isolated in our laboratory almost coincided with each other indicating that the source of bacteria was probably the same. In vitro, S. Enteritidis were sensitive to OFLX, TFLX, FOM, most of PCs, CEPs, AGs but resistant to MPIPC, CAM, CLDM, VCM. Therefore we administered LVFX to 59 cases (alone in 45cases, combination with FOM in 6 cases), NFLX to two children and FMOX to one pregnant woman. Lactobacillus was administered to 28 cases (45.2%) and antidiarrhetics were given to 6 cases (9.7%). Finally all patients improved within two weeks. We suspect that the
salmonella food poisoning
was due to infected egg. The partially cooked omelet would permit the growth of a sufficient inoculum to cause disease. To prevent food poisoning, we have to be consistent in cooking the food well (at 75 degrees C, for more than 1 minute) and should not have omelets during the hot summer season.

Salmonellosis
is ubiquitous and is a world-wide public health concern. Liver abscesses are occasionally reported in Salmonella typhi infections, they are a very rare complication of Salmonella paratyphi infections. A 28 year old male patient without any prior medical history presented with fever,
abdominal pain
and a tender hepatomegaly. The imaging studies revealed multiple liver abscesses and an ultrasound (US) guided aspiration of the abscess yielded heavy growth of Salmonella paratyphi A. He was treated successfully by percutaneous drainage of the abscesses and appropriate antibiotics.

Salmonellosis
is a worldwide health problem; Salmonella infections are the second leading cause of bacterial foodborne illness in the United States. Approximately 95% of cases of human salmonellosis are associated with the consumption of contaminated products such as meat, poultry, eggs, milk, seafood, and fresh produce. Salmonella can cause a number of different disease syndromes including gastroenteritis, bacteremia, and typhoid fever, with the most common being gastroenteritis, which is often characterized by
abdominal pain
, nausea, vomiting, diarrhea, and headache. Typically the disease is self-limiting; however, with more severe manifestations such as bacteremia, antimicrobial therapy is often administered to treat the infection. Currently, there are over 2,500 identified serotypes of Salmonella. A smaller number of these serotypes are significantly associated with animal and human disease including Typhimurium, Enteritidis, Newport, Heidelberg, and Montevideo. Increasingly, isolates from these serotypes are being detected that demonstrate resistance to multiple antimicrobial agents, including third-generation cephalosporins, which are recommended for the treatment of severe infections. Many of the genes that encode resistance are located on transmissible elements such as plasmids that allow for potential transfer of resistance among strains. Plasmids are also known to harbor virulence factors that contribute to Salmonella pathogenicity. Several serotypes of medical importance, including Typhimurium, Enteritidis, Newport, Dublin, and Choleraesuis, are known to harbor virulence plasmids containing genes that code for fimbriae, serum resistance, and other factors. Additionally, many Salmonella contain pathogenicity islands scattered throughout their genomes that encode factors essential for bacterial adhesion, invasion, and infection. Salmonella have evolved several virulence and antimicrobial resistance mechanisms that allow for continued challenges to our public health infrastructure.

Salmonellosis
is a bacterial disease that causes acute gastroenteritis, with sudden onset of headache,
abdominal pain
, diarrhoea, nausea and sometimes vomiting. Infection is often associated with the consumption of foods prepared using raw eggs. During July to August 2008 an outbreak at an aged care facility (ACF) in New South Wales was confirmed as Salmonella Typhimurium phage type 44 (Stm 44) in eight of 45 residents. Two additional probable cases also occurred. Cases were located in each unit of the ACF and for 5 cases, onset of diarrhoea was between 45 to 64 hours (median of 46 hours) after consumption of a dessert containing raw eggs. Onset for 5 further cases occurred up to 9 days after this meal. Eggs were supplied to the ACF from a local farm. Stm 44 was detected on an egg in an unopened box at the ACF from this supplier. The raw-egg dessert was epidemiologically implicated as the likely source of the Salmonella and delayed onset cases may have resulted from ingestion of a smaller dose of Salmonella, or ongoing transmission through cross-contamination of kitchen machinery or surfaces. This outbreak demonstrates that inadequate cooking of eggs continues to pose a risk for Salmonella infection in settings with vulnerable populations. The findings of the investigation provide support for the importance of food safety regulations and demand further advocacy for measures to reduce the risks associated with the distribution, storage and preparation of shell eggs.

Although salmonellosis is a common endemo-epidemic disease in Benin, there is a paucity of data about it. The purpose of this cross-sectional study was to determine the incidence of major salmonellosis requiring hospitalizaton and to describe its epidemiological, clinical, and serologic features as well as treatment and outcome. Consecutive cases observed at the Medical Department of Parakou University Hospital in Benin between January 1, 2005 and December 31 2007 were included.
Salmonellosis
was defined on the basis of clinical and serological criteria. Among the 2,520 patients hospitalized during the study period, salmonellosis was diagnosed in 135 (5.4% [95% CI 4.5%-6.3%]). Highest incidences were observed in January, July, October and November. The main symptoms were headache, fever, fatigue and
abdominal pain
. The Salmonella typhi serotype was identified in 94.8% of patients. Two patients presented co-infection, i.e., Salmonella typhi with paratyphi A in one case and Salmonella typhi with paratyphi B in the other. Fluoroquinolones were used for treatment in 79.3% of patients. Outcome was favorable in 62.2%. The main complications were,typhoid digestive perforation in 11.1%, and gastrointestinal bleeding in 8.1%. The mortality rate was 4.4% (n=6). These data are consistent with previous reports in the literature and confirm the frequency and severity of salmonellosis in Benin.

Salmonella
are Gram-negative rod-shaped facultative anaerobic bacteria that are comprised of over 2,000 serovars. They cause gastroenteritis (salmonellosis) with headache,
abdominal pain
and diarrhea clinical symptoms.
Salmonellosis
brings a heavy burden for the public health in both developing and developed countries. Antibiotics are usually effective in treating the infected patients with severe gastroenteritis, although antibiotic resistance is on the rise. Understanding the molecular mechanisms of
Salmonella
infection is vital to combat the disease.
In vitro
immortalized 2-D cell lines,
ex vivo
tissues/organs and several animal models have been successfully utilized to study
Salmonella
infections. Although these infection models have contributed to uncovering the molecular virulence mechanisms, some intrinsic shortcomings have limited their wider applications. Notably, cell lines only contain a single cell type, which cannot reproduce some of the hallmarks of natural infections. While
ex vivo
tissues/organs alleviate some of these concerns, they are more difficult to maintain, in particular for long term experiments. In addition, non-human animal models are known to reflect only part of the human disease process. Enteroids and induced intestinal organoids are emerging as effective infection models due to their closeness in mimicking the infected tissues/organs. Induced intestinal organoids are derived from iPSCs and contain mesenchymal cells whereas enteroids are derive from intestinal stem cells and are comprised of epithelial cells only. Both enteroids and induced intestinal organoids mimic the villus and crypt domains comparable to the architectures of the
in vivo
intestine. We review here that enteroids and induced intestinal organoids are emerging as desired infection models to study bacterial-host interactions of
Salmonella
.

Salmonella
spp. are among the most important foodborne pathogens and the third leading cause of human death among diarrheal diseases worldwide. Animals are the primary source of this pathogen, and animal-based foods are the main transmission route to humans. Thus, understanding the global epidemiology of
Salmonella
serovars is key to controlling and monitoring this bacterium. In this context, this study aimed to evaluate the prevalence and diversity of
Salmonella enterica
serovars in animal-based foods (beef, pork, poultry, and seafood) throughout the five continents (Africa, the Americas [North and Latin America], Asia, Europe, and Oceania). The meta-analysis consisted of a chemometric assessment (hierarchical cluster analysis and principal component analysis) to identify the main epidemiological findings, including the prevalence and diversity of the
Salmonella
serovars in each matrix. Regarding the serovar distribution,
S
Typhimurium presented a cosmopolitan distribution, reported in all four assessed matrices and continents; poultry continues to play a central role in the dissemination of the Enteritidis serovar to humans, and Anatum and Weltevreden were the most frequently found in beef and seafood, respectively. Additionally, we recommended careful monitoring of certain serovars, such as Derby, Agona, Infantis, and Kentucky. Finally, given the scientific data regarding the most frequently reported serovars and which matrices constitute the main vehicles for the transmission of this pathogen, control programs may be improved, and specific interventions may be implemented in an attempt to reduce the risk of this pathogen reaching humans.
IMPORTANCE
Salmonellosis
is caused by
Salmonella
spp. and is the third leading cause of death among food-transmitted diseases. This pathogen is commonly disseminated in domestic and wild animals, and the infection's symptoms are characterized by acute fever, nausea,
abdominal pain
, and diarrhea. The animals are the primary source of salmonellae, and animal-based foods are the main transmission route to humans. Therefore, data collected from these sources could contribute to future global interventions for effective control and surveillance of
Salmonella
along the food chain. In light of this, the importance of our research is in identifying the prevalence of
Salmonella
serovars in four animal-based food matrices (pork, poultry, beef, and seafood) and to evaluate the importance that each matrix has as the primary source of this pathogen to humans.

Salmonellosis
as a zoonotic disease in dogs is not fully understood, and various reports have pointed to the transmission of antibiotic-resistant salmonella from dogs to humans. The current study aimed to evaluate the serologic and bacteriologic prevalence of Salmonella spp. in stray dogs placed in animal shelters around Tehran, compare the results to those of asymptomatic dogs, and determine the serotype of isolated species, as well as their antibiotic susceptibility pattern. A total of 100 fecal swab and blood samples were obtained from symptomatic and apparently healthy dogs (clinically) placed in four animal shelters around Tehran, Iran. Fecal and blood culture, as well as dog food culture, tube agglutination test, serotyping, and antibiotic susceptibility testing were performed on the samples. Fever, lethargy, diarrhea, and
abdominal pain
were observed in all the dogs in the case group, and bloody diarrhea was the least commonly detected symptom in clinical examination. A number of 11 and 4 collected fecal swabs from the case and control groups were positive for Salmonella spp., respectively. The polymerase chain reaction (PCR) also confirmed the laboratory tests results. Blood culture on the selective medium was negative for all the cases. Moreover, 60% and 100% of dogs in the case and control groups showed inflammatory markers in their blood test. The tube agglutination test was positive for 12% of the samples from the case group, while it was positive only for 5% of cases in the control group. The highest and lowest antibiotic resistance was observed against gentamicin and ciprofloxacin from the case group, respectively. Salmonella spp. infection in stray dogs placed in animal shelters is a great public health concern. In this regard, it is recommended that these animals be regularly monitored since they serve as Salmonella carriers.

Salmonellosis
remains an important public health problem worldwide, particularly in the developing countries such as Ethiopia. A cross-sectional study was conducted to determine the prevalence, antibiotic susceptibility profile, and associated risk factors of
Salmonella
isolate among diarrheal patients who were visiting Dessie Referral Hospital, Dessie, Northeast Ethiopia, from November 2016 to January 2017. 384 stool samples were collected using sterile stool cups. Out of these, 20 (5.21%) were found to be positive for
Salmonella
species. The distribution of positive samples among the three age groups indicated that
Salmonella
species were predominantly prevalent in the age group of three months (0.25 years) to 4 years old patients.
Abdominal pain
, vomiting, watery consistency of stool, and 1-5 days of diarrhea were the clinical features that were significantly associated with salmonellosis. Eating raw vegetables and fruits, consumption of street-vended foods, cohabitation of animals, using water from the unprotected source, absence of latrine, and consumption of raw products of animals such as eggs and raw milk were the risk factors that were significantly associated with the prevalence of
Salmonella
species. The antibiotic sensitivity test was performed for the isolated
Salmonella
species against 5 currently recommended antibiotics. The antimicrobial sensitivity study carried out using the Kirby-Bauer disk diffusion method showed that 100% of
Salmonella
isolates were sensitive to ciprofloxacin and 80% sensitive to nalidixic acid, respectively. Among them, twenty isolated
Salmonella
species resistant to ampicillin, tetracycline, and trimethoprim-sulfamethoxazole were 100%, 85%, and 80%, respectively. This study revealed that
Salmonella
species were prevalent among diarrheal patients who were visiting Dessie Referral Hospital, and therefore, routine diagnosis of patients with diarrhea cases is required, and drugs must be prescribed after performing the sensitivity test, or checking the updated information on the local antibiotics pattern is always necessary.
