A case of Arizona osteomyelitis of the spine which occurred 11 months after an episode of gastroenteritis and enteric fever is presented. As close biochemical and antigenic relative of Salmonella, Arizona infection produces a similar clinical course with gastrointestinal manifestations frequently preceding localized infections by several months. The boney lesion in the present case and in three of the four other cases of Arizona osteomyelitis described in the literature was a chronic inflammation which may have a xanthomatous component. The bone destruction caused by Arizona infection is less severe than that of tuberculosis or pyogenic osteomyelitis. Proposed treatment of Arizona osteomyelitis consists of debridement of the localized infection and long term antimicrobial therapy.

Edwardsiella tarda, a member of the family Enterobacteriaceae, has recently become recognized as pathogenic, especially in patients with an underlying illness. In the present report, a patient had sickle cell hemoglobinopathy and E tarda bacteremia. Other cases of serious infection with Edwardsiella are reported in the literature. Edwardsiella infection may present as bacteremia, enteric fever, gastroenteritis, localized infection, and an asymptomatic carrier state. On the basis of this review, bacteremia with E tarda often has been associated with septic shock and has a high mortality, but this may be related to the usual presence of a serious underlying illness in these patients.

Provided here are the descriptions of 18 patients with focal infections caused by Salmonella spp no-typhi occurring in a period of seven years at the Puerta de Hierro Clinic. In all cases, there was at least one local factor, treatment, or underlying illness associated with decreased resistance to infection. Antecedents of severe gastroenteritis were found in seven cases (38 percent). Eighty-three percent had previous or concomitant bacteremia caused by the same serotype of Salmonella isolated in the focal infection. S. enteritidis was the most prevalent serotype (66 percent). The most common localizations were plueropulmonary (5), osteoarticular (5), and intravascular (3). Relapsing infection was demonstrated in five cases. There was 28 percent mortality. Statistically, age greater than 65 years and the absence of surgical intervention were associated with a worse prognosis.

Fever is one of the most frequent signs seen in children at consultation. In infants under the age of 3 months, fever is nonspecific and is often the only sign of a potentially severe infection. It has been estimated that two-thirds of the children hospitalized have a viral infection and 10% a bacterial infection with risks of complications including meningitis. It must be recalled that 5% of the infants with septicaemia due to Haemophilus influenzae b who does not receive an appropriate treatment will develop meningitis or another focal infection. There is agreement on the definition of potentially severe infections: meningitis, osteoarthritis, cellulitis or cellulodermitis, urinary infection, lung infection and gastroenteritis. Certain authors also include inner ear infections. In suspected cases, the need for hospitalization can be based on signs of impaired consciousness and/or muscle tone, abnormal heart rate, blood pressure or recoloration time, paleness, cyanosis, respiratory distress, signs of dehydration, or abnormal behaviour. In order to identify infants at low risk, in addition to the physical examination, the clinician can rely on essential laboratory tests: white cell count with differential count, blood culture, C-reactive protein and/or sedimentation rate with fibrinogen and an urinanalysis. A chest X-ray is required in case of respiratory signs and a culture of the fecal matter is needed in case of diarrhoea. On the basis of these findings and the clinical picture, if the criteria of low risk of bacterial infection are fulfilled in an infant under 3 months of age with fever, most authors agree that a spinal tap must nevertheless be performed. When these tests lead to the conclusion of low risk, close surveillance at home is appropriate. If the clinical picture worsens within 24h hospitalization is required.

Non-typhoid Salmonella infection in man has been divided into five clinical groups: gastroenteritis, enteric fever, bacteraemia, chronic carrier state and localized infection. This classification has neither pathogenic nor prognostic significance. We retrospectively reviewed the charts of 183 patients with extraintestinal salmonellosis who presented to our institution during a period of 32 years. Patients were classified into four groups: primary bacteraemia (PB), enteritis-associated bacteraemia (secondary bacteraemia) (SB), digestive focal infection (DI) and non-digestive focal infection (NDI). Sex, age, acquisition, underlying disease and outcome were compared between patients with bacteraemia and diseases with focal infection. The differences found between PB and SB were: community acquisition (66% in PB and 85% in SB, p = 0.06) severe immunosuppression (53% in PB and 15% in SB, p < 0.001) and mortality (37% in PB and 3% in SB, p < 0.001). The differences found between NDI and DI were: age over 60 years (45% in NDI and 18% in DI, p < 0.05), severe immunosuppression (51% in NDI and 12% DI, p < 0.001) and associated bacteraemia (38% in NDI and 6% in DI, p < 0.001). This classification of extraintestinal salmonellosis may have pathogenic and prognostic implications, and could help us to understand the clinical significance of this disease.

A total of 134 cases of salmonella infections have been noted during the past 10 years in our hospital. Cases of non-typhoidal salmonellosis increased gradually but infections due to Salmonella typhi did not show the same trend. Gastroenteritis was the most prevalent diagnosis in patients below 1 year of age and non-typhoidal bacteraemia and localized infections were the most prevalent in patients over 50 years. Diabetes mellitus was an important underlying disease especially in patients with localized infections (86%). Travelling history played an important role in cases of enteric fever. The susceptibility pattern in non-typhoidal salmonella changed markedly over the study period; multiple drug resistance was noted. The susceptibility pattern of S. typhi showed no significant change. Seven deaths due to salmonella infections were noted (5.2%); all due to non-typhoidal salmonellosis, especially serogroup B. Age above 50 years, localized infection, infection with serogroup B and diabetes were poor prognostic factors.

Salmonella has three clinical presentations: self-limiting gastroenteritis, a systemic syndrome (enteric or typhoid fever), and bacteremia with focal infection. Hematogenous infections can cause focal lesions, but unusual manifestations occur more often when predisposing factors such as T cell defect, hemolytic disorders (sickle cell disease, malaria) or trauma are present. Salmonella tend to invade bones and joints. There is no mention of acute idiopathic (immune) thrombocytopenic purpura as a predisposing factor for salmonella septic arthritis; however there are reports about the importance of platelets for the immune response. Here we present a case of Salmonella enteritidis septic arthritis following acute idiopathic (immune) thrombocytopenic purpura in a 15-year-old female patient who has been on steroid therapy for the last two weeks.

Nontyphoidal Salmonella are important foodborne pathogens that cause gastroenteritis, bacteremia, and subsequent focal infection. These hardy bacteria are especially problematic in a wide variety of immunocompromised individuals, including (but not limited to) patients with malignancy, human immunodeficiency virus, or diabetes, and those receiving corticosteroid therapy or treatment with other immunotherapy agents. Endovascular infection and deep bone or visceral abscesses are important complications that may be difficult to treat. The site of infection and the individual's immune status influence treatment choices. The harbingers of resistance of nontyphoidal Salmonella to both fluoroquinolones and third-generation cephalosporins have been reported recently, and such resistance is likely to be a therapeutic problem in the future. The current report presents a brief overview of the problems and trends associated with salmonellosis that are of interest to the infectious diseases clinician.

Salmonellosis is a common infection estimated to affect 3 billion people and to cause 200,000 deaths every year. Infections can appear as enteric fever, gastroenteritis, bacteremia, or extraintestinal focal infection. The course of the disease depends on a variety of factors, including infective dose, immune status of the host, and the genetic background of both the host and the pathogen. It has been recognized that certain Salmonella types play a major role in the epidemiology of Salmonella. Here we describe a DNA microarray comprised of 282 sixty-mer oligonucleotide probes to study the epidemiology of Salmonella enterica subsp. enterica isolates at the genotypic level. The probes detect targets encoding genes associated with pathogenicity, antibiotic resistance, fimbriae, prophages, flagella (H antigens), lipopolysaccharides (O antigens), plasmids, insertion sequence elements, and metabolism. The probes are printed on glass slides, and whole-genomic fluorescence-labeled Salmonella DNA is hybridized to the substrate. For quality assurance, a number of controls are included on the microarray.

Salmonella serotypes most often produce gastroenteritis, enteric fever, bacteremia, vascular infection and chronic carrier state. Localized infection may occur at any site after Salmonella bacteremia. Pulmonary involvement due to Salmonella infection is rare. Empyema occurs usually in elderly patients or in patients with underlying diseases such as diabetes mellitus, malignancy, or pulmonary disease. We report the case of an 83-year-old male diabetic patient who presented with fever, productive cough, and difficulty in swallowing. The chest radiographs revealed soft shadowing mild atelactasis and pulmonary abscess on left side. CT-guided aspiration of pus was done. Salmonella enterica serotype typhi was isolated from pus sample. Pleural empyema or abscess usually requires surgical drainage in addition to antimicrobial therapy. After complete course of antimicrobial therapy, the patient improved.
